Description

Technical Field

[0001] This utility model relates to the field of control valve technology, and more specifically, to a multi-way valve. Background Technology

[0002] Currently, multi-way valves typically consist of a valve body and a valve core. The valve body has multiple flow ports on its side wall, and the valve core is rotatably mounted inside the valve body to connect with different flow ports, thereby enabling the switching of the multi-way valve.

[0003] In existing technologies, to ensure the clearance between the valve core and the valve body, a sealing element is typically fitted at the port where the valve core mates with the flow port. This sealing element seals against the inner wall of the valve body to prevent the high-pressure fluid inside the valve body from mixing with the low-pressure fluid inside the valve core. However, due to the design of existing four-way valves, the valve body maintains high pressure while the valve core maintains low pressure. As the valve core rotates through the flow port, the low-pressure flow port connects with the inner cavity of the valve body. Due to the pressure difference between the valve core and the valve body, the sealing element experiences an axial deflection force, causing it to tilt towards the flow port. As the valve core continues to rotate, the sealing element may be bent or even broken, damaging the multi-way valve. Utility Model Content

[0004] This invention provides a multi-way valve to solve the problem that the internal seals of existing multi-way valves are prone to breakage.

[0005] This utility model provides a multi-way valve, which includes: a valve body having a valve cavity and multiple flow ports; a valve core having a communication port at one end, the valve core being rotatably disposed within the valve cavity so that the communication port can selectively communicate with the flow ports; and a sealing assembly sleeved on the end of the valve core having the communication port to seal the gap between the flow ports and the communication port. The sealing assembly includes an annular seal and a reinforcing member, the reinforcing member being annularly disposed on the annular seal and fixedly connected to the annular seal to improve the structural strength of the sealing assembly.

[0006] Furthermore, the annular seal is sealed to the outer wall of the valve core, and the reinforcing member is fitted around the outer circumference of the annular seal. The structural strength of the reinforcing member is greater than that of the annular seal.

[0007] Furthermore, the sealing assembly also includes a sealing ring, which is disposed between the valve core and the annular seal. The inner ring of the sealing ring is fitted with the outer wall of the valve core, and the outer ring of the sealing ring is fitted with the inner wall of the annular seal.

[0008] Furthermore, the annular seal has an abutment protrusion on the side facing the flow port, the abutment protrusion abuts against the inner wall surface of the valve body with the flow port, and the sealing ring and the abutment protrusion are spaced apart along the axial direction of the annular seal.

[0009] Furthermore, the annular seal has a first receiving groove at one end along the axial direction, and the sealing ring is fixedly disposed in the first receiving groove.

[0010] Furthermore, the inner wall of the reinforcing member has a second receiving groove arranged in an annular shape, and a portion of the annular seal is disposed within the second receiving groove.

[0011] Furthermore, the reinforcing member includes a first body and a second body, which are separately arranged along the axial direction of the reinforcing member. The first body has a first slot on the side facing the second body, and the second body has a second slot on the side facing the first body. The first slot and the second slot cooperate to form a second receiving groove, and the first body and the second body are fixedly connected.

[0012] Furthermore, the first body and the second body are fixedly connected by fasteners, and multiple fasteners are provided, which are arranged in a ring at intervals.

[0013] Furthermore, the reinforcing member includes a side wall portion and a limiting portion and a bending portion disposed opposite to each other along the axial direction of the reinforcing member. The side wall portion, the limiting portion and the bending portion cooperate to form a second receiving groove. The limiting portion and the side wall portion are integrally formed. The side wall portion is bent towards the valve core to form the bending portion.

[0014] Furthermore, the sidewall portion includes an extension section and a bent section that are connected to each other. The end of the extension section away from the bent section is connected to the sidewall portion, and the thickness of the bent section is less than the thickness of the extension section.

[0015] Furthermore, the multiple connecting ports include a first flow port, a second flow port, a third flow port, and a fourth flow port. The valve core has a valve core cavity, one end of which is connected to the second flow port, and the other end of which is connected to either the third or fourth flow port. When the valve core cavity is connected to the third flow port, the valve core cavity, the second flow port, and the third flow port form a first flow channel. The valve cavity, the first flow port, and the fourth flow port are connected and form a second flow channel spaced apart from the first flow channel. When the valve core cavity is connected to the fourth flow port, the valve core cavity, the second flow port, and the fourth flow port form the first flow channel. The valve cavity, the first flow port, and the third flow port are connected and form a second flow channel spaced apart from the first flow channel. The first flow channel is used for flowing low-pressure fluid, and the second flow channel is used for flowing high-pressure fluid.

[0016] Furthermore, the sealing assembly also includes an elastic structure disposed between the connection port and the flow port, the elastic structure being used to provide an elastic force to the annular seal in the direction of the flow port.

[0017] By applying the technical solution of this application, the sealing assembly has an annular seal and a reinforcing member. The annular seal seals the connection port and the flow port, preventing internal leakage in the multi-way valve caused by the connection between the high-pressure chamber and the low-pressure chamber, thus ensuring the sealing performance inside the multi-way valve. The reinforcing member is annularly arranged on the annular seal, which can enhance the structural strength of the annular seal. By placing the reinforcing member externally on the annular seal, it prevents the annular seal from flipping inward into the flow port and breaking when it rotates with the valve core, thereby ensuring the structural strength of the overall sealing assembly, improving the performance of the multi-way valve, and reducing the maintenance burden of the multi-way valve.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0040] like Figures 1 to 10As shown, this embodiment of the utility model provides a multi-way valve, which includes a valve body 100, a valve core 200, and a sealing assembly 300. The valve body 100 includes a housing 110 and an end cap 120, which together form a valve cavity 101. Both the housing 110 and the end cap 120 have multiple flow ports 102. The valve core 200 has a connecting port 201 at its end, and the valve core 200 is rotatably disposed within the valve cavity 101 so that the connecting port 201 can selectively communicate with the flow port 102. The sealing assembly 300 is sleeved on the end of the valve core 200 with the connecting port 201 to seal the gap between the flow port 102 and the connecting port 201. The sealing assembly 300 includes an annular seal 310 and a reinforcing member 320. The reinforcing member 320 is annularly disposed on the annular seal 310 and fixedly connected to the annular seal 310 to improve the structural strength of the sealing assembly 300.

[0041] Specifically, such as Figure 2 and Figure 3 As shown, the plurality of flow ports 102 include a first flow port 102D, a second flow port 102S, a third flow port 102E, and a fourth flow port 102C. The valve core 200 has a valve core cavity. One end of the valve core cavity is connected to the second flow port 102S, and the other end of the valve core cavity is connected to either the third flow port 102E or the fourth flow port 102C. When the valve core cavity is connected to the third flow port 102E, the valve core cavity, the second flow port 102S, and the third flow port 102E form a first flow channel. The valve core cavity, the first flow port 102D, and the fourth flow port 102C are connected and form a second flow channel spaced apart from the first flow channel. When the valve core cavity is connected to the fourth flow port 102C, the valve core cavity, the second flow port 102S, and the fourth flow port 102C form the first flow channel. The valve core cavity, the first flow port 102D, and the third flow port 102E are connected and form a second flow channel spaced apart from the first flow channel. The first flow channel is used for flowing low-pressure fluid, and the second flow channel is used for flowing high-pressure fluid. During the rotation of the valve core 200, the fluid inside the valve core 200 is always low-pressure, while the fluid inside the valve cavity 101 is always high-pressure. The annular seal 310 is subjected to the pressure of the high-pressure fluid and will abut against the end cover 120 to achieve a seal and prevent internal leakage between the valve core 200 and the valve cavity.

[0042] However, during the rotation of the valve core 200, the third flow port 102E or the fourth flow port 102C will partially connect with the valve cavity. Before the switching process is complete, the third flow port 102E or the fourth flow port 102C is the low-pressure section, and the valve cavity is the high-pressure section. (Refer to...) Figure 4As shown, the support point formed by the edge of the annular seal 310 and the third flow port 102E or the fourth flow port 102C forms a fulcrum shaft 01. The annular seal 310 on one side of the fulcrum shaft 01 is located in the high-low pressure connection section, while the sealing assembly on the other side is located in the high pressure section. The different forces acting on the annular seal 310 on both sides of the fulcrum shaft 01 will exert a deflection torque on the annular seal 310. Because the annular seal 310 located in the high-low pressure connection section is subjected to high pressure on one side and low pressure on the other, the annular seal 310 here will be subjected to a resultant force towards the low pressure section. This resultant force is greater than the force acting on the annular seal 310 located entirely in the high pressure section. That is, the annular seal 310 will generate a force that flips towards the third flow port 102E or the fourth flow port 102C, causing it to flip inwards. Currently, PTFE material is usually used to make the annular seal 310, which reduces the impact on the rotation of the valve core 200 while ensuring sealing performance.

[0043] By applying the technical solution of this application, the sealing assembly 300 has an annular seal 310 and a reinforcing member 320. The annular seal 310 seals the connecting port 201 and the flow port 102, preventing internal leakage in the multi-way valve caused by the connection between the high-pressure chamber and the low-pressure chamber, thus ensuring the sealing performance inside the multi-way valve. The reinforcing member 320 is annularly disposed on the annular seal 310, which can strengthen the structural strength of the annular seal 310. By placing the reinforcing member 320 externally on the annular seal 310, it prevents the annular seal 310 from flipping inward into the flow port 102 and breaking when it rotates with the valve core 200, thereby ensuring the structural strength of the overall sealing assembly 300, improving the performance of the multi-way valve, and reducing the maintenance frequency of the multi-way valve.

[0044] Specifically, the annular seal 310 is sealed to the outer wall of the valve core 200 to achieve a seal between the annular seal 310 and the valve core 200. The reinforcing member 320 is sleeved on the outer periphery of the annular seal 310. The structural strength of the reinforcing member 320 is greater than that of the annular seal 310, so as to provide support and protection for the annular seal 310, improve the impact resistance and deformation resistance of the annular seal 310, prevent the annular seal 310 from breaking due to the action of the flow port 102 after deflection, and improve the stability of the sealing assembly 300.

[0045] Reference Figures 5 to 10As shown, the sealing assembly 300 also includes a sealing ring 330, which is disposed between the valve core 200 and the annular seal 310 to achieve a seal between the valve core 200 and the annular seal 310. The inner ring of the sealing ring 330 fits against the outer wall of the valve core 200 to form a sealing point, and the outer ring of the sealing ring 330 fits against the inner wall of the annular seal 310 to form another sealing point. The two sealing points formed can seal the gap between the annular seal 310 and the valve core 200, preventing high-pressure gas from entering the valve cavity through the gap between the annular seal 310 and the valve core 200, thereby reducing the internal leakage of the multi-way valve.

[0046] Specifically, the sealing ring 330 can be made of soft rubber material, which can deform to a certain extent after assembly to provide a larger sealing area and ensure the sealing performance of the sealing ring 330.

[0047] Specifically, the reinforcing member 320 can be made of metal, such as steel or copper, to ensure that the reinforcing member 320 strengthens the structural strength of the sealing assembly 300.

[0048] Furthermore, the annular seal 310 has an abutment protrusion 311 on the side facing the flow port 102. The abutment protrusion 311 abuts against the inner wall surface of the valve body 100 with the flow port 102. In this embodiment, by abutting against the inner wall surface of the valve body 100, the contact area between the annular seal 310 and the inner wall surface of the valve body 100 can be reduced, thereby helping to reduce the friction force that needs to be overcome when driving the valve core 200 to rotate and improving the switching speed of the multi-way valve. The sealing ring 330 and the abutment protrusion 311 are spaced apart along the axial direction of the annular seal 310. In this way, the annular seal 310 can form a third sealing point with the valve body 100. Through this sealing point, the gap between the valve core 200 and the valve cavity 101 is sealed, thereby achieving the sealing effect of the sealing assembly 300.

[0049] Specifically, in this application, the sealing point formed between the sealing ring 330 and the annular seal 310, and the sealing point formed between the abutting protrusion 311 and the end cap 120, can seal the gap between the side wall of the valve core 200 and the sealing assembly 300, as well as the gap between the valve core 200 and the end cap 120, preventing fluid in the valve cavity 101 from entering the valve core 200, thus forming a comprehensive seal for the first flow channel and the second flow channel. Applying the technical solution provided in this application, there is no need to consider the sealing effect between the reinforcing member 320 and the annular seal 310; therefore, only the assembly effect between the reinforcing member 320 and the annular seal 310 needs to be considered, eliminating the need for additional sealing points, reducing the structural complexity between the reinforcing member 320 and the annular seal 310, and facilitating the design and processing of the sealing assembly 300.

[0050] In some feasible embodiments of this application, the annular seal 310 has a first receiving groove 312 at one end along the axial direction, and the sealing ring 330 is fixedly disposed in the first receiving groove 312 to limit the displacement of the sealing ring and prevent the sealing ring from falling off.

[0051] In some feasible embodiments of this application, the first receiving groove 312 may also be provided on the side wall of the valve core 200, or a groove-shaped receiving structure may be provided on both the side wall of the valve core 200 and the side wall of the annular seal 310.

[0052] Specifically, the inner wall of the reinforcing member 320 has a second receiving groove arranged in an annular shape, and a portion of the annular seal 310 is disposed in the second receiving groove so as to improve the stability of the connection between the annular seal 310 and the reinforcing member 320 and limit the relative displacement between the reinforcing member 320 and the annular seal 310 by making the annular seal 310 cooperate with the reinforcing member 320 to form an interlocking structure.

[0053] Furthermore, the annular seal 310 can be interference-fitted with the reinforcing member 320 to ensure the stability of the connection between the annular seal 310 and the reinforcing member 320.

[0054] In this application, the reinforcing member 320 can cover the outer side of the annular seal 310 along the side wall away from the valve core direction, without interfering with the sealing ring 330. Thus, there is no need to seal the gap between the reinforcing member 320 and the valve core 200, reducing the sealing performance requirements.

[0055] Furthermore, the abutment protrusion 311 needs to protrude from the end face of the reinforcing member 320 facing the corresponding flow port 102, so as to ensure that only the abutment protrusion 311 seals with the valve body 100 and prevents the reinforcing member 320 from being worn.

[0056] In some feasible embodiments of this application, a groove-shaped structure or a hole-shaped structure may be provided inside the annular seal 310, and a reinforcing member 320 may be provided inside the annular seal 310 to form a reinforcing rib structure, so as to improve the structural strength of the annular seal 310.

[0057] Please refer to Figures 5 to 7As shown, in the first embodiment of this application, the reinforcing member 320 includes a first body 321 and a second body 322. The first body 321 and the second body 322 are separately disposed along the axial direction of the reinforcing member 320. The first body 321 has a first groove on the side facing the second body 322, and the second body 322 has a second groove on the side facing the first body 321. The first groove and the second groove cooperate to form a second receiving groove. The first body 321 and the second body 322 are fixedly connected. With this configuration, the reinforcing member 320 has a separate structure, which facilitates the clamping of the annular seal 310 between the first body 321 and the second body 322 during the assembly of the reinforcing member 320 and the annular seal 310, thereby improving the stability of the assembly.

[0058] Specifically, the first body 321 and the second body 322 are fixedly connected by fasteners. Multiple fasteners are provided and are arranged in a ring with intervals. The fasteners can be screws or rivets, etc., to ensure a stable connection between the first body 321 and the second body 322.

[0059] Alternatively, the first body 321 and the second body 322 can also be connected via a snap-fit ​​connector.

[0060] Please refer to Figures 8 to 10 As shown, in the second embodiment of this application, the reinforcing member 320 includes a sidewall portion 323 and a limiting portion 324 and a bending portion disposed opposite to each other along the axial direction of the reinforcing member 320. The sidewall portion 323, the limiting portion 324 and the bending portion cooperate to form a second receiving groove. The limiting portion 324 and the sidewall portion 323 are integrally formed. The sidewall portion 323 is bent towards the valve core 200 to form the bending portion. With this configuration, compared with the first embodiment of this application, the reinforcing member 320 is an integrally formed structure. The annular seal 310 is clamped by the bending portion and the limiting portion 324. While meeting the requirements of the annular seal 310, the assembly efficiency of the sealing assembly 300 can be improved, saving the cost of fasteners and separate metal processing.

[0061] Specifically, the sidewall portion 323 includes an extension section 3231 and a bent section 3232 connected to each other. The end of the extension section 3231 facing away from the bent section 3232 is connected to the sidewall portion 323. The thickness of the bent section 3232 is less than the thickness of the extension section 3231. This arrangement facilitates bending of the bent section 3232, prevents the bent section 3232 from breaking during bending due to excessive thickness, and improves processing convenience.

[0062] Furthermore, the thickness of the bending segment 3232 can be gradually reduced in the direction away from the limiting part 324, so that the structural strength of the bending segment 3232 can be improved while facilitating bending.

[0063] Furthermore, the sealing assembly 300 also includes an elastic structure 340, which is disposed between the connecting port 201 and the flow port 102. The elastic structure 340 provides an elastic force to the annular seal 310 in the direction of the flow port 102. The elastic structure 340 includes a mounting seat sleeved on the valve core 200 and multiple springs. The mounting seat is used to mount the springs, and the springs abut against the reinforcing member 320. With this configuration, the elastic force provided by the elastic structure 340 to the annular seal 310 ensures a good seal between the annular seal 310 and the end cap 120. At the same time, when the annular seal 310 wears, the elastic structure 340 can compensate for the wear, ensuring that the annular seal 310 always maintains contact with the end cap 120, reducing the risk of internal leakage in the multi-way valve.
