Description

Technical Field

[0001] This invention relates to the field of flow path control technology for refrigeration systems, and in particular to an electric valve. Background Technology

[0002] Electric valves are generally controlled by actuators. When the actuator is connected to the valve body, a bracket assembly is often installed in the middle. When the bracket assembly is positioned on the valve body, it needs to be circumferentially anti-rotated and axially fixed to prevent the bracket assembly supporting the actuator from moving or deflecting due to the rotation of the valve core. Summary of the Invention

[0003] To address the problems in the background art, this invention discloses an electric valve, comprising a valve body component, a valve core component, a bracket, and a valve cover. The valve body component includes a valve body and a mounting seat. The valve core component is at least partially located in a valve cavity inside the valve body. The mounting seat is located on one side of the valve body and protrudes outward relative to the valve body. The bracket abuts against the mounting seat, and the valve cover is sleeved on the bracket. The valve cover and the mounting seat are detachably connected, and the abutment between the valve cover and the bracket restricts the axial displacement of the bracket. The mounting seat includes a positioning surface and a positioning structure, and the bracket includes a mating surface and a mating structure. The mounting surface abuts against the mating surface, and the positioning structure is inserted into the mating structure to restrict the circumferential rotation of the bracket relative to the mounting seat. There are two positioning structures, spaced apart along the circumference of the positioning surface.

[0004] This invention improves the circumferential fit between the positioning structure and the mating structure by setting a plug-in positioning structure and a mating structure between the bracket and the mounting seat of the electric valve, and by setting two positioning structures spaced apart. At the same time, the valve cover is used to limit the axial displacement of the bracket, thereby improving the stability of the bracket and preventing the bracket from being displaced or deflected due to the rotation of the valve core during the operation of the solenoid valve.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other technical solutions obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the accompanying drawings, shapes and dimensions may be enlarged for clarity, and the same reference numerals will be used in all figures to indicate the same or similar parts.

[0033] In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, and lower are defined relative to the structure shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other orientations should not be interpreted as restrictive terms.

[0034] Terms involving attachment, connection, etc., refer to the relationship in which these structures are fixed or restrained by direct connection to each other or by indirect connection through intermediate structures, as well as movable or rigid attachment, unless otherwise clearly stated.

[0035] 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.

[0036] To achieve the above-mentioned objectives and other advantages of the present invention, the present invention provides the following technical solutions:

[0037] This invention provides an electric valve, such as Figures 1 to 11As shown, the electric valve includes a valve body component 1, a bracket 2, a valve cover 4, a valve core component 5, and a drive assembly 6.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, valve body component 1 includes a valve body 10 and a mounting base 11. The mounting base 11 is located on one side of the valve body 10 and protrudes outward relative to the valve body 10. The interior of the valve body 10 includes a valve cavity 100. The mounting base 11 includes a mounting port 111, which communicates with the valve cavity 100. A bracket 2 abuts against the mounting base 11, and a valve cover 4 is sleeved on the bracket 2 and abuts against the bracket 2. Simultaneously, the valve cover 4 is detachably connected to the mounting base 11 to limit and fix the bracket 2 to the mounting base 11, preventing the bracket 2 from detaching from the mounting base 11. Further, the mounting base 11 includes a positioning surface 110 and a positioning structure 12. The bracket 2 includes a mating surface 222 and a mating structure 23. The positioning structure 12 and the mating structure 23 are inserted into each other. When inserted into place, the positioning surface 110 abuts against the mating surface 222 to restrict the circumferential rotation of the bracket 2 relative to the mounting base 11.

[0039] Furthermore, two positioning structures 12 are provided, spaced circumferentially apart on the positioning surface 110. The spacing mentioned herein refers to the absence of direct contact. Furthermore, the two positioning structures 12 are located on opposite sides of the mounting port 111. Figure 2 As shown, when the mounting port 111 is circular, the two positioning structures 12 are located on both sides of the radial direction of the mounting port 111. The mating structure 23 is correspondingly set with the positioning structure 12. Compared with a single or unilateral positioning structure 12, the dual positioning structure 12 located on both sides can improve the uniformity of force distribution and increase the mating strength and reliability of the positioning structure 12 and the mating structure 23.

[0040] Furthermore, such as Figure 2 , Figure 4 As shown, the bracket 2 includes a base portion 21 and a crimping portion 22. The crimping portion 22 is located on the side of the base portion 21 facing the mounting base 11 and protrudes outward perpendicular to the outer wall surface of the base portion 21, forming an annular boss. The crimping portion 22 includes a mating surface 222 on one side facing the mounting base 11 and a crimping surface 221 on the other side. Specifically, as shown... Figure 4As shown, the mating surface 222 and the pressing surface 221 are located on the upper and lower surfaces of the annular boss, respectively. The valve cover 4 is cap-shaped and includes a stepped portion 42 with a downward-facing stepped surface abutting against the pressing surface 221. The side wall of the mounting base 11 is provided with a threaded portion 13, and the side wall of the stepped portion 42 is provided with a threaded mating portion 41. After the valve cover 4 is fitted onto the bracket 2, the mating structure 23 and the positioning structure 12 are inserted into place, and the mating surface 222 abuts against the positioning surface 110. Rotating the valve cover 4 causes the threaded portion 13 and the threaded mating portion 41 to engage. Compared with other connection methods, the connection between the valve cover 4 and the mounting base 11 using a threaded connection facilitates disassembly and assembly.

[0041] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the valve core component 5 and the drive assembly 6 are at least partially located within the valve cavity 100. Specifically, the valve core component 5 includes a ball valve core 52 and a valve stem 51, and the drive assembly 6 includes an actuator 60, an output shaft 61, and an adapter 62. The bracket 2 includes a mounting channel 210 along the longitudinal direction of the electric valve, and the actuator 60 is mounted on top of the bracket 2. Further, the drive assembly 6 includes a base 63, to which the bracket 2 is fixedly connected, and the actuator 60 is mounted on top of the base 63.

[0042] The output end of the actuator 60 is connected to the output shaft 61. The output shaft 61 extends at least partially into the mounting hole 210 and is connected to one side of the adapter 62. The other side of the adapter 62 is connected to the valve stem 51, which is fixedly connected to the ball valve core 52, which is located within the valve cavity 100. When the actuator 60 is energized, it drives the output shaft 61 to rotate, thereby causing the ball valve core 52 to rotate. When the output shaft 61, adapter 62, and valve stem 51 rotate, friction will occur at the contact points with the bracket 2. Therefore, in order to prevent the bracket 2 from shifting due to the influence of the drive assembly 6 and the valve core during the operation of the electric valve, which would cause the actuator 60 to deflect and the ball valve core 52 to misalign, the present invention employs the aforementioned positioning structure 12 and mating structure 23 to prevent the bracket 2 from rotating.

[0043] Furthermore, the output shaft 61 and valve stem 51 are respectively inserted and fixed to the adapter 62. The adapter 62 includes an upper groove 621 and a lower groove 622. Correspondingly, the end of the output shaft 61 near the adapter 62 includes a shaft mating section 611, and the end of the valve stem 51 near the adapter 62 includes a valve stem mating section 511. Furthermore, the sidewalls of the upper groove 621 and the lower groove 622 include straight wall portions. The shaft mating section 611 and the valve stem mating section 511 are formed by cutting or grinding into straight sections that mate with the straight wall portions. During insertion and mating, the straight sections abut against the straight wall portions to prevent slippage, while also better transmitting power. On the other hand, the adapter 62 is injection molded, which makes it easier for the upper groove 621 and the lower groove 622 to be better molded to fit the size of the output shaft 61 and the valve stem 51. This allows for differentiated design of the length and diameter of the output shaft 61 and the valve stem 51, ensuring the miniaturization of the valve body. Compared with the long shaft design where the output shaft 61 and the valve stem 51 are integrated, the split structure is easier to process and manufacture. Compared with the split structure where the output shaft 61 and the valve stem 51 are connected by a sleeve, adding a connector and using a plug-in fixing can effectively reduce the diameter of the valve stem 51 while ensuring transmission efficiency and connection strength.

[0044] Furthermore, such as Figure 3 , Figure 4 As shown, the electric valve of the present invention also includes a first seal 71 and a second seal 72. The outer wall 623 of the adapter 62 includes an annular groove, and the second seal 72 is fitted into the annular groove. The second seal 72 is clearance-fitted with the mounting channel 210, and the second seal 72 may be an O-ring. Installing an O-ring on the adapter 62 can effectively prevent leakage from the valve body, which would cause fluid to enter the actuator 60 through the mounting channel 210. The first seal 71 is located between the valve cover 4 and the bracket 2, and the second seal 72 is a metal gasket to prevent fluid inside the valve body from seeping into the inside of the valve cover 4 through the gap between the positioning surface 110 and the mating surface 222 and leaking out from the valve cover 4.

[0045] In one embodiment, the positioning structure 12 and the mating structure 23 employ a concave-convex fit. Specifically, as shown... Figure 8 As shown, the positioning structure 12 is a positioning boss 121 protruding relative to the positioning surface 110. The positioning boss 121 includes a first boss top 1211 and a first boss sidewall 1212, and the first boss sidewall 1212 is perpendicular to the positioning surface 110. The mating structure 23 is a mating groove 231 recessed relative to the mating surface 222. The mating groove 231 includes a first groove bottom 2311 and a first groove sidewall 2312, and the first groove sidewall 2312 is perpendicular to the mating surface 222. The first boss top 1211 abuts against the first groove bottom 2311, and the first boss sidewall 1212 and the first groove sidewall 2312 are in clearance fit. Further, the positioning boss 121 on the mounting base 11 is double-crescent-shaped, and the mating structure 23 on the bracket 2 is a groove with an arc edge that is adapted to the positioning boss 121.

[0046] Or, such as Figure 9 As shown, the mating structure 23 is a mating boss 232 protruding from the mating surface 222. The mating boss 232 includes a second boss top 2321 and a second boss sidewall 2322, which is perpendicular to the mating surface 222. The positioning structure 12 is a positioning groove 122 recessed from the end face of the mounting base 11. The positioning groove 122 includes a second groove bottom 1221 and a second groove sidewall 1222, which is perpendicular to the end face of the mounting base 11. The second boss top 2321 abuts against the second groove sidewall 1222, and the second boss sidewall 2322 and the second groove sidewall 1222 are in clearance fit. Further, the positioning structure 12 is a groove radially arranged along the positioning surface 110 and passing through the mounting port 111. The groove can be machined by milling. Correspondingly, the mating structure 23 on the bracket 2 is a double boss that can be inserted into the groove.

[0047] In one embodiment, such as Figure 10 As shown, the bracket 2 includes a mating structure 23, which is hole-shaped and recessed relative to the end face of the bracket 2 facing the mounting base 11; the mounting base 11 includes a positioning structure 12, which is hole-shaped and recessed relative to the end face of the mounting base 11 facing the bracket 2.

[0048] The electric valve also includes a positioning pin 3. When the bracket 2 is in contact with the mounting base 11, the positioning structure 12 and the mating structure 23 are positioned opposite each other. One part of the positioning pin 3 is inserted into the positioning structure 12, and the other part of the positioning pin 3 is inserted into the mating structure 23 to restrict the circumferential rotation of the bracket 2 relative to the mounting base 11. Specifically, a countersunk hole is provided on the positioning surface 110, and a through hole is provided on the pressing part 22 of the bracket 2 to connect the pressing surface 221 and the mating surface 222. The position and diameter of the through hole and the countersunk hole correspond. The positioning pin 3 can pass through the through hole and the countersunk hole to limit the circumferential positioning of the bracket 2 and the mounting base 11. Then, the bracket 2 is fixed on the mounting base 11 by the valve cover 4 to ensure that the mounting hole 210 on the bracket 2 and the mounting port 111 on the mounting base 11 are coaxial.

[0049] In one embodiment, such as Figure 11 As shown, the bracket 2 includes a mating structure 23, which is groove-shaped and recessed inward relative to the outer wall surface of the bracket 2 facing the mounting base 11.

[0050] Mounting base 11 includes positioning structure 12, which is groove-shaped and recessed inward relative to the outer wall surface of the mounting base 11 facing the bracket 2.

[0051] The electric valve also includes a positioning pin 3. When the bracket 2 is in contact with the mounting base 11, the positioning structure 12 and the mating structure 23 are positioned opposite each other. One part of the positioning pin 3 is engaged with the positioning structure 12, and the other part of the positioning pin 3 is engaged with the mating structure 23 to restrict the circumferential rotation of the bracket 2 relative to the mounting base 11. Specifically, the mating structure 23 is a square through groove that is recessed from the side wall of the pressing part 22 and penetrates the pressing surface 221 and the mating surface 222. Correspondingly, the positioning structure 12 is a square groove that is recessed relative to the side wall of the mounting base 11. The positioning pin 3 is a square pin. When the through groove and the groove are positioned opposite each other, the square pin is engaged with the square through groove and the square groove, so that the bracket 2 and the mounting base 11 are circumferentially limited. Then, the bracket 2 is fixed on the mounting base 11 by the valve cover 4, ensuring that the mounting hole 210 on the bracket 2 and the mounting port 111 on the mounting base 11 are coaxial. Furthermore, when the square pin is engaged in the square through slot and the square recess, along the radial direction of the mounting base 11, the position of the side of the square pin opposite to the threaded engagement portion 41 of the valve cover 4 is lower than the lowest position of the threaded portion 13 on the mounting base 11, so as to avoid interference between the positioning pin 3 and the threaded portion 13, which would cause the thread engagement to fail.

[0052] In one embodiment, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the electric valve in this invention is a three-way ball valve. Specifically, the valve core component 5 includes a valve stem 51 and a spherical valve core 52. The spherical valve core 52 includes a valve core flow channel 521, which has three openings. The valve stem 51 and the spherical valve core 52 mate at an arc-shaped engagement protrusion, and the top of the spherical valve core 52 has an arc-shaped engagement groove. The arc-shaped engagement protrusion and the arc-shaped engagement groove are connected so that the valve stem 51 drives the spherical valve core 52 to rotate.

[0053] The valve body 10 includes an inlet 101, a first outlet 102, and a second outlet 103 communicating with the valve cavity 100. The electric valve also includes connecting pipes 8, which include an inlet connecting pipe 81 communicating with the inlet 101, a first outlet connecting pipe 82 communicating with the first outlet 102, and a second outlet connecting pipe 83 communicating with the second outlet 103. Further, the inlet 101 is located at the bottom end of the valve cavity 100, and its position is opposite to the valve stem 51. The opening at the inlet position in the valve core flow channel 521 corresponds to the position of the inlet 101. The first outlet 102 and the second outlet 103 are located on opposite sides of the valve body 10, and the two outlet openings in the valve core flow channel 521 corresponding to the outlets are set at 90° to allow selective communication between the valve core flow channel 521 and either the first outlet 102 or the second outlet 103. When one of the outlet openings is connected to the first outlet 102, the other outlet opening is opposite to the inner wall of the valve body 10, and the second outlet 103 is blocked by the ball valve core 52. Furthermore, the first outlet 102 and the second outlet 103 are equipped with seals that can cooperate with the outer wall of the ball valve core 52 to block the first outlet 102 or the second outlet 103.

[0054] Through the above structural design, the electric valve of this invention can ensure the stable position of the bracket 2 when the actuator 60 drives the valve core assembly to rotate, and is not affected by the reaction force of the valve core assembly rotation. The rotation angle of the valve core assembly is controlled by the actuator 60. With the bracket 2 structure stable and the output of the actuator 60 unchanged, there is no need to add other limiting structures to restrict the rotation angle of the valve core assembly 5, simplifying the transmission control structure of the electric valve and improving the stability of the electric valve port switching action.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above examples illustrate the principles and implementation methods of the present invention. The descriptions of these embodiments are merely illustrative and are intended to aid in understanding the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the present invention.
