Technical Field

[0001] This invention relates to the field of fluid regulation, and in particular to a control component. Background Technology

[0002] Control components are widely used in production and daily life. They are devices that use a moving part to open, close, or partially block one or more openings or channels, allowing liquid flow, air flow, or other airflow or a large amount of loose material to flow out, be blocked, or be regulated.

[0003] A control component in a related technology includes a valve body and a valve seat. When assembling the valve body and valve seat, at least a portion of the valve body needs to be inserted into the valve seat first. Then, a pin connection is used to achieve a limiting connection between the valve body and the valve seat. During the assembly process, the valve body and valve seat need to be pre-fitted and stabilized with external force to prevent relative displacement between them. Then, the pin is inserted to achieve a limiting connection between the valve body and the valve seat, thus completing the assembly between the valve body and the valve seat. The assembly process is relatively complex. Summary of the Invention

The valve seat includes a receiving cavity, and at least a portion of the valve body is located in the receiving cavity. The valve seat includes a first wall portion, and a mounting opening corresponding to the receiving cavity is located in the first wall portion. The valve body includes an ear portion extending radially away from the valve core portion and abutting against the first wall portion. The control assembly includes a first mating portion and a second mating portion. The first mating portion is located in one of the first wall portion and the ear portion, and the second mating portion is located in the other of the first wall portion and the ear portion. The second mating portion includes a first hole, and at least a portion of the first mating portion is confined in the first hole.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0044] The technical solution of the specific embodiments is described below with reference to the accompanying drawings:

[0045] In one embodiment, reference is made to... Figures 1-9 The control assembly includes a valve core 1, a valve body 2, and a valve seat 3. At least a portion of the valve core 1 is located in the valve body 2. The valve seat 3 includes a receiving cavity 31, and at least a portion of the valve body 2 is located in the receiving cavity 31. The valve seat 3 includes a first wall 33, and a mounting port 32 corresponding to the receiving cavity 31 is located in the first wall 33. The valve body 2 includes an ear 21, at least a portion of which extends radially away from the valve core 1 along the valve core 1 and abuts against the first wall 33. That is, during assembly, at least a portion of the valve body 2 extends into the receiving cavity 31 from the mounting port 32 until the ear 21 abuts against the first wall 33, i.e., the valve body 2 and the valve seat 3 abut against each other. More specifically, the extension direction of the valve core 1 is the depth direction of the receiving cavity 31, i.e., during assembly, at least a portion of the valve body 2 extends into the receiving cavity 31 from the mounting port 32 along the extension direction of the valve core 1 until the ear 21 abuts against the first wall 33.

[0046] The control component includes a first mating part 4 and a second mating part 5. The first mating part 4 is located in one of the first wall part 33 and the ear part 21, and the second mating part 5 is located in the other of the first wall part 33 and the ear part 21. The second mating part 5 includes a first hole 51, at least a portion of the first mating part 4 is confined in the first hole 51, and the first mating part 4 includes a resilient mating head 41, which is engaged with the second mating part 5.

[0047] Such a control component is configured to engage with the second mating part 5 through a flexible mating head 41, with at least a portion of the first mating part 4 confined within the first hole 51, thereby limiting the valve body 2 and valve seat 3 and making installation more convenient.

[0048] Specifically, refer to Figures 1-9 The first mating part 4 is located on the first wall part 33, and the second mating part 5 is located on the ear part 21. The first mating part 4 includes an extension part 42, and the first hole 51 includes a first segment 511. The size of the hole corresponding to the first segment 511 is adapted to the outer diameter size corresponding to the extension part 42. At least a portion of the extension part 42 is located in the first segment 511. The extension direction of the extension part 42 is opposite to the extension direction of the valve core part 1, that is, during the installation of the valve body part 2 and the valve seat 3, at least a portion of the extension part 42 is inserted into the first segment 511. Along the extension direction of the extension part 42, at least a portion of the mating head 41 is located at one end of the extension part 42, that is, the mating head 41 is located at one end of the extension part 42, and the other end of the extension part 42 is limited or fixedly connected to the valve seat 3. A first plane 6 is defined, which is perpendicular to the extension direction of the extension part 42. The projection of the extension part 42 onto the first plane 6 is shown. The extension part 42 is located on the inner circumferential side of the first mating wall 52. The second mating part 5 includes the first mating wall 52, and the first mating wall 52 abuts against the mating head 41. That is, refer to Figure 2 and Figure 4 In the projection of the first plane 6, the outer diameter L2 of the mating head 41 is greater than the outer diameter L1 of the extension 42. The first mating wall 52 abuts against the mating head 41. That is, along the extension direction of the extension 42, at least part of the wall corresponding to the first segment 511 is limited between the mating head 41 and the valve seat 3, thereby realizing the limiting setting of the valve body 2 and the valve seat 3.

[0049] Of course, there are several ways to connect the first mating part 4 and the valve seat 3:

[0050] For example, refer to Figure 3 , Figure 4 , Figure 8 and Figure 9 The first mating part 4 is made of metal, the valve seat 3 is made of metal, and the first mating part 4 and the valve seat 3 are welded together.

[0051] For example, refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 The first mating part 4 includes a metal part 47 made of metal and a connector made of plastic. The valve seat 3 is made of metal. The first mating part 4 and the valve seat 3 are connected by an insert. That is, the metal part 47 and the valve seat 3 are placed in the mold of the connector. After the connector is produced, the first mating part 4 and the valve seat 3 are connected by an insert.

[0052] More specifically, the first mating part 4 includes at least two elastic folds 43, each elastic fold 43 including at least a portion of the mating head 41 and at least a portion of the extension 42, the at least two elastic folds 43 being distributed circumferentially along the wall portion corresponding to the first segment 511, and there being a gap between the unit elastic folds 43. During the installation of the valve body 2 and the valve seat 3, at least a portion of the mating head 41 corresponding to the elastic folded wall 43 abuts against the wall corresponding to the first section 511. The elastic folded wall 43 is subjected to force and elastically deforms along the thickness direction of the elastic folded wall 43, that is, the elastic folded wall 43 converges radially. The first mating part 4 continues to move along the extension direction of the extension part 42. When the valve body 2 and the valve seat 3 abut against each other, that is, when the ear 21 abuts against the first wall 33, the extension part 42 enters the first section 511. The force corresponding to the first section 511 on at least a portion of the mating head 41 corresponding to the elastic folded wall 43 disappears, and the elastic folded wall 43 rebounds, causing the mating head 41 to abut against the first mating wall 52, thereby achieving the limiting setting of the valve body 2 and the valve seat 3. Compared to other implementation methods, this installation method involves elastic deformation of the elastic folding wall 43 during the insertion of the valve body 2 into the receiving cavity 31. This deformation ensures the engagement of the first mating part 4 and the second mating part 5 at the corresponding position of the valve body 2 within the receiving cavity 31, making installation more convenient. For example, after the valve body 2 is inserted into the receiving cavity 31 along the extension direction of the valve core 1 to the corresponding position, additional force needs to be applied to stabilize the valve body 2 and the valve seat 3. Then, a pin is inserted perpendicular to the extension direction of the valve core 1 to limit the movement of the valve body 2 and the valve seat 3, which is more cumbersome.

[0053] Specifically, the first hole 51 is a through hole, and the first hole 51 includes a second segment 512. The first segment 511 and the second segment 512 are connected and extend along the extension direction of the extension portion 42. The first mating wall 52 is located between the wall corresponding to the first segment 511 and the wall corresponding to the second segment 512. The hole diameter corresponding to the second segment 512 is larger than the hole diameter corresponding to the first segment 511. At least a portion of the mating head 41 is located in the second segment 512. That is, during the assembly of the valve body 2 and the valve seat 3, the portion of the mating head 41 corresponding to the elastic folding wall 43 is first located in the first segment 511. At this time, the portion of the mating head 41 corresponding to the elastic folding wall 43 is squeezed by the wall corresponding to the first segment 511 and undergoes elastic deformation along the thickness direction of the elastic folding wall 43. The elastic fold wall 43 deforms radially. As the valve body 2 and valve seat 3 move relative to each other, the part of the mating head 41 corresponding to the elastic fold wall 43 enters the second section 512. The aperture size of the second section 512 is larger than that of the first section 511, and the elastic fold wall 43 rebounds. In addition, the first hole 51 is a through hole, which facilitates the disassembly of the valve body and valve seat 3. From the side of the ear 21 opposite to the valve body 2, the elastic fold wall 43 is applied in the thickness direction, so that the elastic fold wall 43 is radially converged, causing the elastic fold wall 43 to deform. The outer diameter of the mating head 41 is reduced to the size that can enter the first section 511. The valve body 2 and valve seat 3 move relative to each other, so the valve seat 3 and valve body 2 can be disassembled.

[0054] More specifically, the wedge-shaped fit between the head 41 and the first mating wall 52 makes it easier for the first mating part 4 to bear force compared to other embodiments, avoiding excessive force that could damage the head 41. For example, if the first mating wall 52 is perpendicular to the wall corresponding to the first segment 511, or even if the clockwise angle between the first mating wall 52 and the wall corresponding to the first segment 511 is less than 90 degrees, the connection between the first mating wall 52 and the wall corresponding to the first segment 511 will exert a large force on the first mating part 4, which could easily cause the first mating part 4 to break or be damaged.

[0055] More specifically, the mating head 41 includes a receiving area 44 located on one side of the elastic folded wall 43 in the thickness direction. The control component includes a plug portion 7, at least a portion of which is located in the receiving area 44. The elastic folded wall 43 is located on the outer periphery of the plug portion 7, and the plug portion 7 and the elastic folded wall 43 abut against each other. More specifically, the plug portion 7 and the portion of the mating head 41 corresponding to the elastic folded wall 43 abut against each other. The elastic folded wall 43 is abutted against by the plug portion 7 and the wall portion corresponding to the second segment 512 on both sides in the thickness direction, which increases the mating strength and prevents the elastic folded wall 43 from deforming and falling off after long-term use. More specifically, the first hole 51 is a through hole. When at least a portion of the mating head 41 corresponding to the elastic folded wall 43 is located in the second segment 512, the plug portion 7 can be installed into the receiving area 44 from the side opposite to the valve seat 3 through the first hole 51.

[0056] More specifically, to facilitate the mating of the first mating part 4 and the second mating part 5, the valve body part 2 and the valve seat 3 are installed, refer to... Figure 2 , Figure 4 , Figure 7 and Figure 9 Along the extending direction of the extension 42, the first mating part 4 includes a first end 45 and a second end 46. The first end 45 is located at the mating head 41. Along the direction from the first end 45 to the second end 46, the outer diameter of at least a portion of the outer edge of the first end 45 gradually increases. And / or, the first hole 51 has a third segment 513, which communicates with the first segment 511. The third segment 513 is a variable diameter segment, and the hole diameter corresponding to the third segment 513 gradually decreases toward the first segment 511. Along the extending direction of the extension 42, the first segment 511 is closer to the mating head 41 than the third segment 513. One port corresponding to the third segment 513 is the port corresponding to the first hole 51. More specifically, along the extending direction of the extension 42, the first mating part 4 includes a first end 45 and a second end 46. The first end 45 is located at the mating head 41. Along the direction from the first end 45 to the second end 46, the outer diameter of at least a portion of the first end 45 gradually increases. The first hole 51 has a third segment 513, which communicates with the first segment 511. The third segment 513 is a variable diameter segment, and the hole diameter corresponding to the third segment 513 gradually decreases towards the first segment 511. Along the extending direction of the extension 42, the first segment 511 is closer to the mating head 41 than the third segment 513. One port corresponding to the third segment 513 is the port corresponding to the first hole 51. That is, during the process of at least a portion of the valve body 2 being inserted into the receiving cavity 31 along the extending direction of the valve core 1, the first end 45 first abuts against the wall corresponding to the third segment 513, and the first end 45 and the wall corresponding to the third segment 513 are wedge-shaped engaged. Compared with other embodiments, this makes it easier for the first end 45 to be subjected to force and undergo elastic deformation. For example, the first hole 51 includes a first section 511, that is, during the process of inserting at least a portion of the valve body 2 into the receiving cavity 31 along the extension direction of the valve core 1, before the extension 42 enters the first section 511, the mating head 41 mates with the wall corresponding to the port of the first section 511. The mating surface is small, or even a line mating, which makes it inconvenient for the mating head 41 to bear force.

[0057] More specifically, see reference Figure 7 and Figure 9 The extension 42 includes a main body 421 and an extension arm 422. The extension arm 422 is located on the elastic fold wall 43, and the thickness of the extension arm 422 is greater than at least a portion of the thickness of the main body 421. This increases the strength of the extension arm 422, thereby enhancing the service life of the first mating part 4.

[0058] In one embodiment, reference is made to... Figures 6-14 The control assembly includes a valve core 1, a valve body 2, and a valve seat 3. At least a portion of the valve core 1 is located in the valve body 2. The valve seat 3 includes a receiving cavity 31, and at least a portion of the valve body 2 is located in the receiving cavity 31. The valve seat 3 includes a first wall 33, and a mounting port 32 corresponding to the receiving cavity 31 is located in the first wall 33. The valve body 2 includes an ear 21, at least a portion of which extends radially away from the valve core 1 along the valve core 1 and abuts against the first wall 33. That is, during assembly, at least a portion of the valve body 2 extends into the receiving cavity 31 from the mounting port 32 until the ear 21 abuts against the first wall 33, i.e., the valve body 2 and the valve seat 3 abut against each other. More specifically, the extension direction of the valve core 1 is the depth direction of the receiving cavity 31, i.e., during assembly, at least a portion of the valve body 2 extends into the receiving cavity 31 from the mounting port 32 along the extension direction of the valve core 1 until the ear 21 abuts against the first wall 33.

[0059] The control component includes a first mating part 4 and a second mating part 5. The first mating part 4 is located in one of the first wall part 33 and the ear part 21, and the second mating part 5 is located in the other of the first wall part 33 and the ear part 21. The second mating part 5 includes a first hole 51, at least a portion of the first mating part 4 is confined in the first hole 51, and the first mating part 4 includes a resilient mating head 41, which is engaged with the second mating part 5.

[0060] Such a control component is configured to engage with the second mating part 5 through a flexible mating head 41, with at least a portion of the first mating part 4 confined within the first hole 51, thereby limiting the valve body 2 and valve seat 3 and making installation more convenient.

[0061] Specifically, refer to Figures 6-14 The first mating part 4 is located on the first wall part 33, and the second mating part 5 is located on the ear part 21. The first mating part 4 includes an extension part 42, and the first hole 51 includes a first segment 511. The size of the hole corresponding to the first segment 511 is adapted to the radial size corresponding to the extension part 42. At least a portion of the extension part 42 is located on the first segment 511. The extension direction of the extension part 42 is opposite to the extension direction of the valve core part 1, that is, during the installation of the valve body part 2 and the valve seat 3, at least a portion of the extension part 42 is inserted into the first segment 511. Along the extension direction of the extension part 42, at least a portion of the mating head 41 is located at one end of the extension part 42, that is, the mating head 41 is located at one end of the extension part 42, and the other end of the extension part 42 is limited or fixedly connected to the valve seat 3. A first plane 6 is defined, which is perpendicular to the extension direction of the extension part 42. The projection of the extension part 42 onto the first plane 6 is shown. The extension part 42 is located on the inner circumferential side of the first mating wall 52. The second mating part 5 includes the first mating wall 52, and the first mating wall 52 abuts against the mating head 41. That is, refer to Figure 11 and Figure 13In the projection of the first plane 6, the outer diameter L2 of the mating head 41 is greater than the radial dimension L1 of the extension 42. The first mating wall 52 abuts against the mating head 41. That is, along the extension direction of the extension 42, at least part of the wall corresponding to the first segment 511 is limited between the mating head 41 and the valve seat 3, thereby realizing the limiting setting of the valve body 2 and the valve seat 3.

[0062] Of course, there are several ways to connect the first mating part 4 and the valve seat 3:

[0063] For example, refer to Figure 8 , Figure 9 , Figure 12 and Figure 13 The first mating part 4 is made of metal, the valve seat 3 is made of metal, and the first mating part 4 and the valve seat 3 are welded together.

[0064] For example, refer to Figure 6 , Figure 7 , Figure 10 and Figure 11 The first mating part 4 includes a metal part 47 made of metal and a connector made of plastic. The valve seat 3 is made of metal. The first mating part 4 and the valve seat 3 are connected by an insert. That is, the metal part 47 and the valve seat 3 are placed in the mold of the connector. After the connector is produced, the first mating part 4 and the valve seat 3 are connected by an insert.

[0065] More specifically, the first mating part 4 includes at least two elastic folds 43, each elastic fold 43 including at least a portion of the mating head 41 and at least a portion of the extension 42, the at least two elastic folds 43 being distributed circumferentially along the wall portion corresponding to the first segment 511, and there being a gap between the unit elastic folds 43. During the installation of the valve body 2 and valve seat 3, at least a portion of the mating head 41 corresponding to the elastic folded wall 43 abuts against the wall corresponding to the first segment 511. The elastic folded wall 43 is subjected to a force along the thickness direction of the elastic folded wall 43, causing the elastic folded wall 43 to converge radially. The elastic folded wall 43 deforms and converges radially. The first mating part 4 continues to move along the extension direction of the extension part 42. When the valve body 2 and valve seat 3 abut against each other, that is, when the ear 21 abuts against the first wall 33, the extension part 42 enters the first segment 511. The force corresponding to the first segment 511 on at least a portion of the mating head 41 corresponding to the elastic folded wall 43 disappears, and the elastic folded wall 43 rebounds, causing the mating head 41 to abut against the first mating wall 52, thereby achieving the limiting setting of the valve body 2 and valve seat 3. Compared to other implementation methods, this installation method involves elastic deformation of the elastic folding wall 43 during the insertion of the valve body 2 into the receiving cavity 31. This deformation ensures the engagement of the first mating part 4 and the second mating part 5 at the corresponding position of the valve body 2 within the receiving cavity 31, making installation more convenient. For example, after the valve body 2 is inserted into the receiving cavity 31 along the extension direction of the valve core 1 to the corresponding position, additional force needs to be applied to stabilize the valve body 2 and the valve seat 3. Then, a pin is inserted perpendicular to the extension direction of the valve core 1 to limit the movement of the valve body 2 and the valve seat 3, which is more cumbersome.

[0066] Specifically, the first hole 51 is a through hole. Along the extension direction of the extension 42, the ear 21 includes a first end wall 211 and a second end wall 212. The first end wall 211 abuts against the first wall portion 33, and the second end wall 212 is located on the opposite side of the first end wall 211 to the ear 21. The first mating wall 52 is connected to the wall portion corresponding to the first segment 511, and the first mating wall 52 is connected to the second end wall 212. That is, during the assembly of the valve body 2 and the valve seat 3, the part of the mating head 41 corresponding to the elastic folding wall 43 is initially located in the first segment 511. At this time, the part of the mating head 41 corresponding to the elastic folding wall 43 is squeezed by the wall portion corresponding to the first segment 511, deforms along the thickness direction of the elastic folding wall 43, and the mating head converges radially. With the relative movement of the valve body 2 and the valve seat 3, the part of the mating head 41 corresponding to the elastic folding wall 43 moves out of the first segment 511. At the same time, the extension 42 enters the first segment 511, and the elastic folding wall 43 springs back. In addition, the first hole 51 is a through hole, which facilitates the disassembly of the valve body and the valve seat 3. From the side opposite to the valve body 2 on the ear 21, a force is applied to the elastic fold wall 43 in the thickness direction of the elastic fold wall 43, causing the elastic fold wall 43 to deform and converge radially. When the outer diameter of the head 41 is reduced to the size that can enter the first section 511, the valve body 2 and the valve seat 3 move relative to each other, and the valve seat 3 and the valve body 2 can be disassembled.

[0067] More specifically, the wedge-shaped fit between the head 41 and the first mating wall 52 makes it easier for the first mating part 4 to bear force compared to other embodiments, avoiding excessive force that could damage the head 41. For example, if the first mating wall 52 is perpendicular to the wall corresponding to the first segment 511, or even if the clockwise angle between the first mating wall 52 and the wall corresponding to the first segment 511 is less than 90 degrees, the connection between the first mating wall 52 and the wall corresponding to the first segment 511 will exert a large force on the first mating part 4, which could easily cause the first mating part 4 to break or be damaged.

[0068] More specifically, the mating head 41 includes a receiving area 4 located on one side of the elastic folded wall 43 in the thickness direction. The control component includes a plug portion 7, at least a portion of which is located in the receiving area 44. The elastic folded wall 43 is located on the outer periphery of the plug portion 7, and the plug portion 7 and the elastic folded wall 43 abut against each other. More specifically, the plug portion 7 and the portion of the mating head 41 corresponding to the elastic folded wall 43 abut against each other, increasing the mating strength and preventing the elastic folded wall 43 from deforming and falling off after long-term use. More specifically, the first hole 51 is a through hole. After at least a portion of the mating head 41 corresponding to the elastic folded wall 43 is removed from the first section 511, the plug portion 7 can be installed into the receiving area 44 on the side of the second end wall 212 where the ear portion 21 is located.

[0069] More specifically, to facilitate the mating of the first mating part 4 and the second mating part 5, the valve body part 2 and the valve seat 3 are installed, refer to... Figure 7 , Figure 9 , Figure 11 and Figure 13 Along the extending direction of the extension 42, the first mating part 4 includes a first end 45 and a second end 46. The first end 45 is located at the mating head 41. Along the direction from the first end 45 to the second end 46, the outer diameter of at least a portion of the outer edge of the first end 45 gradually increases. And / or, the first hole 51 has a third segment 513, which communicates with the first segment 511. The third segment 513 is a variable diameter segment, and the hole diameter corresponding to the third segment 513 gradually decreases toward the first segment 511. Along the extending direction of the extension 42, the first segment 511 is closer to the mating head 41 than the third segment 513. One port corresponding to the third segment 513 is the port corresponding to the first hole 51. More specifically, along the extending direction of the extension 42, the first mating part 4 includes a first end 45 and a second end 46. The first end 45 is located at the mating head 41. Along the direction from the first end 45 to the second end 46, the outer diameter of at least a portion of the first end 45 gradually increases. The first hole 51 has a third segment 513, which communicates with the first segment 511. The third segment 513 is a variable diameter segment, and the hole diameter corresponding to the third segment 513 gradually decreases towards the first segment 511. Along the extending direction of the extension 42, the first segment 511 is closer to the mating head 41 than the third segment 513. One port corresponding to the third segment 513 is the port corresponding to the first hole 51. That is, during the process of at least a portion of the valve body 2 being inserted into the receiving cavity 31 along the extending direction of the valve core 1, the first end 45 first abuts against the wall corresponding to the third segment 513, and the first end 45 and the wall corresponding to the third segment 513 are wedge-shaped engaged. Compared with other embodiments, this makes it easier for the first end 45 to be subjected to force and undergo elastic deformation. For example, the first hole 51 includes a first section 511, that is, during the process of inserting at least a portion of the valve body 2 into the receiving cavity 31 along the extension direction of the valve core 1, before the extension 42 enters the first section 511, the mating head 41 mates with the wall corresponding to the port of the first section 511. The mating surface is small, or even a line mating, which makes it inconvenient for the mating head 41 to bear force.

[0070] More specifically, see reference Figure 7 and Figure 9 The extension 42 includes a main body 421 and an extension arm 422. The extension arm 422 is located on the elastic fold wall 43, and the thickness of the extension arm 422 is greater than at least a portion of the thickness of the main body 421. This increases the strength of the extension arm 422, thereby enhancing the service life of the first mating part 4.

[0071] In one embodiment, reference is made to... Figures 15-23The control assembly includes a valve core 1, a valve body 2, and a valve seat 3. At least a portion of the valve core 1 is located in the valve body 2. The valve seat 3 includes a receiving cavity 31, and at least a portion of the valve body 2 is located in the receiving cavity 31. The valve seat 3 includes a first wall 33, and a mounting port 32 corresponding to the receiving cavity 31 is located in the first wall 33. The valve body 2 includes an ear 21, at least a portion of which extends radially away from the valve core 1 along the valve core 1 and abuts against the first wall 33. That is, during assembly, at least a portion of the valve body 2 extends into the receiving cavity 31 from the mounting port 32 until the ear 21 abuts against the first wall 33, i.e., the valve body 2 and the valve seat 3 abut against each other. More specifically, the extension direction of the valve core 1 is the depth direction of the receiving cavity 31, i.e., during assembly, at least a portion of the valve body 2 extends into the receiving cavity 31 from the mounting port 32 along the extension direction of the valve core 1 until the ear 21 abuts against the first wall 33.

[0072] The control component includes a first mating part 4 and a second mating part 5. The first mating part 4 is located in one of the first wall part 33 and the ear part 21, and the second mating part 5 is located in the other of the first wall part 33 and the ear part 21. The second mating part 5 includes a first hole 51, at least a portion of the first mating part 4 is confined in the first hole 51, and the first mating part 4 includes a resilient mating head 41, which is engaged with the second mating part 5.

[0073] Such a control component is configured to engage with the second mating part 5 through a flexible mating head 41, with at least a portion of the first mating part 4 confined within the first hole 51, thereby limiting the valve body 2 and valve seat 3 and making installation more convenient.

[0074] Specifically, refer to Figures 15-23 The first mating part 4 is located at the ear 21, and the second mating part 5 is located at the valve seat 3. The first mating part 4 includes an extension 42, and the first hole 51 includes a first segment 511. The size of the hole corresponding to the first segment 511 is adapted to the radial size corresponding to the extension 42. At least a portion of the extension 42 is located at the first segment 511, and the extension direction of the extension 42 is the same as the extension direction of the valve core 1. That is, during the installation of the valve body 2 and the valve seat 3, at least a portion of the extension 42 is inserted into the first segment 511. Along the extension direction of the extension 42, at least a portion of the mating head 41 is located at one end of the extension 42. That is, the mating head 41 is located at one end of the extension 42, and the other end of the extension 42 is limited or fixedly connected to the ear 21. The second mating part 5 includes a first mating wall 52, defining a first plane 6. The first plane 6 is perpendicular to the extension direction of the extension 42. The projection of the extension 42 onto the first plane 6 is perpendicular to the projection of the extension 42 onto the first plane 6. The extension 42 is located on the inner circumferential side of the first mating wall 52, and the first mating wall 52 abuts against the mating head 41. That is, refer to Figure 16 and Figure 18In the projection of the first plane 6, the outer diameter L2 of the mating head 41 is greater than the radial dimension L1 of the extension 42. The first mating wall 52 abuts against the mating head 41. That is, along the extension direction of the extension 42, at least part of the wall corresponding to the first segment 511 is limited between the mating head 41 and the ear 21, thereby realizing the limiting setting of the valve body 2 and the valve seat 3.

[0075] Of course, there are several ways to connect the first mating part 4 and the valve seat 3:

[0076] For example, refer to Figure 17 , Figure 18 , Figure 20 and Figure 21 The first mating part 4 is made of metal, the valve body part 2 is made of metal, and the first mating part 4 and the valve body part 2 are welded together.

[0077] For example, refer to the diagram. Figure 15 , Figure 16 , Figure 22 and Figure 23 The first mating part 4 includes a metal part 47 made of metal and a connector made of plastic. The valve body part 2 is made of metal. The first mating part 4 and the valve body part 2 are connected by an insert. That is, the metal part 47 and the valve body part 2 are placed in the mold of the connector. After the connector is produced, the first mating part 4 and the valve seat 3 are connected by an insert.

[0078] More specifically, the first mating part 4 includes at least two elastic folded walls 43. Each elastic folded wall 43 includes at least a portion of a mating head 41 and at least a portion of an extension 42. The at least two elastic folded walls 43 are distributed circumferentially along the wall portion corresponding to the first segment 511, and there is a gap between each unit elastic folded wall 43. That is, during the installation of the valve body 2 and the valve seat 3, at least a portion of the mating head 41 corresponding to the elastic folded wall 43 abuts against the wall portion corresponding to the first segment 511. The elastic folded wall 43 is subjected to force and deforms and converges along the thickness direction of the elastic folded wall 43. The first mating part 4 continues to move along the extension direction of the extension 42. When the valve body 2 and the valve seat 3 abut against each other, that is, when the ear 21 abuts against the first wall portion 33, the extension 42 enters the first segment 511. The force corresponding to the first segment 511 on at least a portion of the mating head 41 corresponding to the elastic folded wall 43 disappears, and the elastic folded wall 43 rebounds, causing the mating head 41 to abut against the first mating wall 52, thereby achieving the limiting setting of the valve body 2 and the valve seat 3. Compared to other implementation methods, in this installation method, the elastic folding wall 43 undergoes elastic deformation during the insertion of the valve body 2 into the receiving cavity 31. When the valve body 2 is inserted into the corresponding position in the receiving cavity 31, the first mating part 4 and the second mating part 5 are engaged, making installation more convenient. Other installation methods, for example, require additional force to stabilize the valve body 2 and valve seat 3 after the valve body 2 is inserted into the receiving cavity 31 along the extension direction of the valve core 1. Then, a pin is inserted perpendicular to the extension direction of the valve core 1 to limit the movement of the valve body 2 and valve seat 3, which is more cumbersome.

[0079] Specifically, the first hole 51 is a through hole, and the first hole 51 includes a second section 512. The first section 511 and the second section 512 are connected and extend along the extension direction of the extension 42. The first mating wall 52 is located between the wall corresponding to the first section 511 and the wall corresponding to the second section 512. The hole diameter corresponding to the second section 512 is larger than the hole diameter corresponding to the first section 511. At least a portion of the mating head 41 is located in the second section 512. That is, during the assembly of the valve body 2 and the valve seat 3, the portion of the mating head 41 corresponding to the elastic folding wall 43 is first located in the first section 511. At this time, the portion of the mating head 41 corresponding to the elastic folding wall 43 is squeezed by the wall corresponding to the first section 511 and deforms along the thickness direction of the elastic folding wall 43. That is, the elastic folding wall 43 converges radially. With the relative movement of the valve body 2 and the valve seat 3, the portion of the mating head 41 corresponding to the elastic folding wall 43 enters the second section 512. The hole diameter corresponding to the second section 512 is larger than the hole diameter corresponding to the first section 511, and the elastic folding wall 43 rebounds. In addition, the first hole 51 is a through hole, which facilitates the disassembly of the valve body and the valve seat 3. From the side of the valve body 2 opposite to the first wall 33, a force is applied to the elastic fold wall 43 in the thickness direction of the elastic fold wall 43 to make the elastic fold wall 43 converge radially, causing the elastic fold wall 43 to deform, that is, the elastic fold wall 43 converges radially. When the outer diameter of the head 41 is reduced to the point that it can enter the first section 511, the valve body 2 and the valve seat 3 move relative to each other, and the valve seat 3 and the valve body 2 can be disassembled.

[0080] More specifically, the wedge-shaped fit between the head 41 and the first mating wall 52 makes it easier for the first mating part 4 to bear force compared to other embodiments, avoiding excessive force that could damage the head 41. For example, if the first mating wall 52 is perpendicular to the wall corresponding to the first segment 511, or even if the counterclockwise angle between the first mating wall 52 and the wall corresponding to the first segment 511 is less than 90 degrees, the connection between the first mating wall 52 and the wall corresponding to the first segment 511 will exert a large force on the first mating part 4, which could easily cause the first mating part 4 to break or be damaged.

[0081] More specifically, the mating head 41 includes a receiving area 4 located on one side of the elastic folded wall 43 in the thickness direction. The control component includes a plug portion 7, at least a portion of which is located in the receiving area 44. The elastic folded wall 43 is located on the outer periphery of the plug portion 7, and the plug portion 7 and the elastic folded wall 43 abut against each other. More specifically, the plug portion 7 and the portion of the mating head 41 corresponding to the elastic folded wall 43 abut against each other. The elastic folded wall 43 is abutted against by the plug portion 7 and the wall portion corresponding to the second segment 512 on both sides in the thickness direction, which increases the mating strength and prevents the elastic folded wall 43 from deforming and falling off after long-term use. More specifically, the first hole 51 is a through hole. When at least a portion of the mating head 41 corresponding to the elastic folded wall 43 is located in the second segment 512, the plug portion 7 can be installed into the receiving area 44 from the side opposite to the ear portion 21 through the first hole 51.

[0082] More specifically, to facilitate the mating of the first mating part 4 and the second mating part 5, the valve body part 2 and the valve seat 3 are installed, refer to... Figure 16 , Figure 17 , Figure 19 , Figure 23 and Figure 25Along the extending direction of the extension 42, the first mating part 4 includes a first end 45 and a second end 46. The first end 45 is located at the mating head 41. Along the direction from the first end 45 to the second end 46, the outer diameter of at least a portion of the outer edge of the first end 45 gradually increases. And / or, the first hole 51 has a third segment 513, which communicates with the first segment 511. The third segment 513 is a variable diameter segment, and the hole diameter corresponding to the third segment 513 gradually decreases toward the first segment 511. Along the extending direction of the extension 42, the first segment 511 is closer to the mating head 41 than the third segment 513. One port corresponding to the third segment 513 is the port corresponding to the first hole 51. More specifically, along the extending direction of the extension 42, the first mating part 4 includes a first end 45 and a second end 46. The first end 45 is located at the mating head 41. Along the direction from the first end 45 to the second end 46, the outer diameter of at least a portion of the first end 45 gradually increases. The first hole 51 has a third segment 513, which communicates with the first segment 511. The third segment 513 is a variable diameter segment, and the hole diameter corresponding to the third segment 513 gradually decreases towards the first segment 511. Along the extending direction of the extension 42, the first segment 511 is closer to the mating head 41 than the third segment 513. One port corresponding to the third segment 513 is the port corresponding to the first hole 51. That is, during the process of at least a portion of the valve body 2 being inserted into the receiving cavity 31 along the extending direction of the valve core 1, the first end 45 first abuts against the wall corresponding to the third segment 513, and the first end 45 and the wall corresponding to the third segment 513 are wedge-shaped engaged. Compared with other embodiments, this makes it easier for the first end 45 to be subjected to force and undergo elastic deformation. For example, the first hole 51 includes a first section 511, that is, during the process of inserting at least a portion of the valve body 2 into the receiving cavity 31 along the extension direction of the valve core 1, before the extension 42 enters the first section 511, the mating head 41 mates with the wall corresponding to the port of the first section 511. The mating surface is small, or even a line mating, which makes it inconvenient for the mating head 41 to bear force.

[0083] More specifically, see reference Figure 21 and Figure 23 The extension 42 includes a main body 421 and an extension arm 422. The extension arm 422 is located on the elastic fold wall 43, and the thickness of the extension arm 422 is greater than at least a portion of the thickness of the main body 421. This increases the strength of the extension arm 422, thereby enhancing the service life of the first mating part 4.

[0084] In one embodiment, reference is made to... Figures 20-28The control assembly includes a valve core 1, a valve body 2, and a valve seat 3. At least a portion of the valve core 1 is located in the valve body 2. The valve seat 3 includes a receiving cavity 31, and at least a portion of the valve body 2 is located in the receiving cavity 31. The valve seat 3 includes a first wall 33, and a mounting port 32 corresponding to the receiving cavity 31 is located in the first wall 33. The valve body 2 includes an ear 21, at least a portion of which extends radially away from the valve core 1 along the valve core 1 and abuts against the first wall 33. That is, during assembly, at least a portion of the valve body 2 extends into the receiving cavity 31 from the mounting port 32 until the ear 21 abuts against the first wall 33, i.e., the valve body 2 and the valve seat 3 abut against each other. More specifically, the extension direction of the valve core 1 is the depth direction of the receiving cavity 31, i.e., during assembly, at least a portion of the valve body 2 extends into the receiving cavity 31 from the mounting port 32 along the extension direction of the valve core 1 until the ear 21 abuts against the first wall 33.

[0085] The control component includes a first mating part 4 and a second mating part 5. The first mating part 4 is located in one of the first wall part 33 and the ear part 21, and the second mating part 5 is located in the other of the first wall part 33 and the ear part 21. The second mating part 5 includes a first hole 51, at least a portion of the first mating part 4 is confined in the first hole 51, and the first mating part 4 includes a resilient mating head 41, which is engaged with the second mating part 5.

[0086] Such a control component is configured to engage with the second mating part 5 through a flexible mating head 41, with at least a portion of the first mating part 4 confined within the first hole 51, thereby limiting the valve body 2 and valve seat 3 and making installation more convenient.

[0087] Specifically, refer to Figures 20-28 The first mating part 4 is located at the ear 21, and the second mating part 5 is located at the valve seat 3. The first mating part 4 includes an extension 42, and the first hole 51 includes a first segment 511. The size of the hole corresponding to the first segment 511 is adapted to the radial size corresponding to the extension 42. At least a portion of the extension 42 is located at the first segment 511, and the extension direction of the extension 42 is the same as the extension direction of the valve core 1. That is, during the installation of the valve body 2 and the valve seat 3, at least a portion of the extension 42 is inserted into the first segment 511. Along the extension direction of the extension 42, at least a portion of the mating head 41 is located at one end of the extension 42. That is, the mating head 41 is located at one end of the extension 42, and the other end of the extension 42 is limited or fixedly connected to the ear 21. The second mating part 5 includes a first mating wall 52, defining a first plane 6. The first plane 6 is perpendicular to the extension direction of the extension 42. The projection of the extension 42 onto the first plane 6 is perpendicular to the projection of the extension 42 onto the first plane 6. The extension 42 is located on the inner circumferential side of the first mating wall 52, and the first mating wall 52 abuts against the mating head 41. That is, refer to Figure 25 and Figure 27In the projection of the first plane 6, the outer diameter of the outer edge of the mating head 41 is greater than the radial dimension of the extension 42. The first mating wall 52 abuts against the mating head 41. That is, along the extension direction of the extension 42, at least part of the wall corresponding to the first segment 511 is limited between the mating head 41 and the ear 21, thereby realizing the limiting setting of the valve body 2 and the valve seat 3.

[0088] Of course, there are several ways to connect the first mating part 4 and the valve seat 3:

[0089] For example, refer to the figure Figure 20 , Figure 21 , Figure 26 and Figure 27 The first mating part 4 is made of metal, the valve body part 2 is made of metal, and the first mating part 4 and the valve body part 2 are welded together.

[0090] For example, refer to Figure 22 , Figure 23 , Figure 23 and Figure 25 The first mating part 4 includes a metal part 47 made of metal and a connector made of plastic. The valve body part 2 is made of metal. The first mating part 4 and the valve body part 2 are connected by an insert. That is, the metal part 47 and the valve body part 2 are placed in the mold of the connector. After the connector is produced, the first mating part 4 and the valve seat 3 are connected by an insert.

[0091] More specifically, the first mating part 4 includes at least two elastic folds 43, each elastic fold 43 including at least a portion of the mating head 41 and at least a portion of the extension 42, the at least two elastic folds 43 being distributed circumferentially along the wall portion corresponding to the first segment 511, and there being a gap between the unit elastic folds 43. During the installation of the valve body 2 and the valve seat 3, at least a portion of the mating head 41 corresponding to the elastic folded wall 43 abuts against the wall corresponding to the first section 511. The elastic folded wall 43 deforms under force along the thickness direction of the elastic folded wall 43 and converges radially. The first mating part 4 continues to move along the extension direction of the extension part 42. When the valve body 2 and the valve seat 3 abut against each other, that is, when the ear 21 abuts against the first wall 33, the extension part 42 enters the first section 511. The force corresponding to the first section 511 on at least a portion of the mating head 41 corresponding to the elastic folded wall 43 disappears, and the elastic folded wall 43 rebounds, causing the mating head 41 to abut against the first mating wall 52, thereby achieving the limiting setting of the valve body 2 and the valve seat 3. Compared to other implementation methods, in this installation method, during the insertion of the valve body 2 into the receiving cavity 31, the elastic folding wall 43 undergoes elastic deformation. When the valve body 2 is inserted into the corresponding position in the receiving cavity 31, the first mating part 4 and the second mating part 5 are engaged, making installation more convenient. In other installation methods, for example, after the valve body 2 is inserted into the receiving cavity 31 to the corresponding position along the extension direction of the valve core 1, an additional force needs to be applied to stabilize the valve body 2 and the valve seat 3, and then a pin is inserted in the direction perpendicular to the extension direction of the valve core 1 to limit the valve body 2 and the valve seat 3, which is more cumbersome.

[0092] Specifically, the first hole 51 is a through hole extending along the extension 42. The valve seat 3 includes a second wall 34 located on the extension 42, opposite to the first wall 33, on the valve body 2. The first wall 33 abuts against the ear 21. The first mating wall 52 is connected to the wall corresponding to the first segment 511, and the first mating wall 52 is connected to the second wall 34. That is, during the assembly of the valve body 2 and the valve seat 3, the part of the mating head 41 corresponding to the elastic folding wall 43 is initially located in the first segment 511. At this time, the part of the mating head 41 corresponding to the elastic folding wall 43 is squeezed by the wall corresponding to the first segment 511, and changes phase along the thickness direction of the elastic folding wall 43, that is, the elastic folding wall converges radially. With the relative movement of the valve body 2 and the valve seat 3, the part of the mating head 41 corresponding to the elastic folding wall 43 moves out of the first segment 511, while the extension 42 enters the first segment 511, and the elastic folding wall 43 springs back. In addition, the first hole 51 is a through hole, which facilitates the disassembly of the valve body and the valve seat 3. From the side where the second wall 34 of the valve body 2 is located, a force is applied to the elastic fold wall 43 in the thickness direction of the elastic fold wall 43 to make the elastic fold wall converge radially, causing the elastic fold wall 43 to deform. When the outer diameter of the head 41 is reduced to the point where it can enter the first section 511, the valve body 2 and the valve seat 3 move relative to each other, and the valve seat 3 and the valve body 2 can be disassembled.

[0093] More specifically, the wedge-shaped fit between the head 41 and the first mating wall 52 makes it easier for the first mating part 4 to bear force compared to other embodiments, avoiding excessive force that could damage the head 41. For example, if the first mating wall 52 is perpendicular to the wall corresponding to the first segment 511, or even if the counterclockwise angle between the first mating wall 52 and the wall corresponding to the first segment 511 is less than 90 degrees, the connection between the first mating wall 52 and the wall corresponding to the first segment 511 will exert a large force on the first mating part 4, which could easily cause the first mating part 4 to break or be damaged.

[0094] More specifically, the mating head includes a receiving area located on one side of the elastic fold wall in the thickness direction. The control component includes a plug portion 7, at least a portion of which is located in the receiving area 44. At least a portion of the elastic fold wall surrounds the outer periphery of the plug portion 7, and the plug portion 7 abuts against the elastic fold wall 43. More specifically, the plug portion 7 abuts against a portion of the mating head 41 corresponding to the elastic fold wall 43 to increase the mating strength and prevent the elastic fold wall 43 from deforming and falling off after prolonged use. More specifically, the first hole 51 is a through hole. After at least a portion of the mating head 41 corresponding to the elastic fold wall 43 is removed from the first segment 511, the plug portion 7 can be installed into the receiving area 44 from the side opposite to the ear portion 21 through the first hole 51.

[0095] More specifically, to facilitate the engagement of the first mating part 4 and the second mating part 5, and the installation of the valve body part 2 and the valve seat 3, along the extending direction of the extension part 42, the first mating part 4 includes a first end 45 and a second end 46. The first end 45 is located at the mating head 41. Along the direction from the first end 45 to the second end 46, the outer diameter of at least a portion of the outer edge of the first end 45 gradually increases; and / or, the first hole 51 has a third segment 513, which communicates with the first segment 511. The third segment 513 is a variable diameter segment, and the hole diameter corresponding to the third segment 513 gradually decreases towards the first segment 511. Along the extending direction of the extension part 42, the first segment 511 is closer to the mating head 41 than the third segment 513. One port corresponding to the third segment 513 is the port corresponding to the first hole 51. More specifically, along the extending direction of the extension 42, the first mating portion 4 includes a first end portion 45 and a second end portion 46. The first end portion 45 is located at the mating head 41. Along the direction from the first end portion 45 to the second end portion 46, the outer diameter of at least a portion of the outer edge of the first end portion 45 gradually increases. The first hole 51 has a third section 513, which communicates with the first section 511. The third section 513 is a variable diameter section, and the hole diameter corresponding to the third section 513 gradually decreases towards the first section 511. Along the extending direction of the extension 42... The first segment 511 is closer to the mating head 41 than the third segment 513. One port of the third segment 513 is the port corresponding to the first hole 51. That is, during the process of at least a portion of the valve body 2 being inserted into the receiving cavity 31 along the extending direction of the valve core 1, before the extension 42 enters the first segment 511, the first end 45 first abuts against the wall corresponding to the third segment 513, and the first end 45 and the wall corresponding to the third segment 513 are wedge-shaped. Compared with other embodiments, this makes it easier for the first end 45 to be stressed and undergo elastic deformation. For example, the first hole 51 includes the first segment 511. That is, during the process of at least a portion of the valve body 2 being inserted into the receiving cavity 31 along the extending direction of the valve core 1, before the extension 42 enters the first segment 511, the mating head 41 is mated with the wall corresponding to the port of the first segment 511. The mating surface is small, or even a line mating, which makes it difficult for the mating head 41 to be stressed.

[0096] More specifically, see reference Figure 21 and Figure 23 The extension 42 includes a main body 421 and an extension arm 422. The extension arm 422 is located on the elastic fold wall 43, and the thickness of the extension arm 422 is greater than at least a portion of the thickness of the main body 421. This increases the strength of the extension arm 422, thereby enhancing the service life of the first mating part 4.

[0097] It should be noted that although this specification has described the present invention in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify, combine or make equivalent substitutions to the present invention, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
