Description
Technical Field
[0001] The utility model relates to the technical field of internal components of air-conditioning equipment, and more specifically, to an integrated quick-connect stop valve. Background Art
[0002] When connecting the indoor and outdoor units of conventional commercial or residential air conditioners and heat pump air conditioners, a shutoff valve is typically installed on the main unit, which is then connected to a flared copper tube nut. Alternatively, the shutoff valve is connected to a male quick connector, which is then connected to a female quick connector copper tube. During the installation or use of the air conditioner, such as during installation operations, calibration, maintenance, cleaning, and refrigerant or heating agent refilling, a large amount of refrigerant or heating agent may leak from the main unit. This can also cause air to enter the main unit, necessitating secondary vacuuming and refilling. This cumbersome and labor-intensive operation requires specialized technicians and specialized equipment and tools. Repeated disassembly and assembly can also damage seals and sealing openings, leading to seal failure, excessive leakage, and explosion hazards. Utility Model Content

[0039] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the orientation or positional relationship indicated by the terms is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0040] like Figures 1 to 4 As shown, the utility model provides an integrated quick connector stop valve, comprising:
[0041] Stop valve body 100;
[0042] The male connector body 200 has one end connected to the interface of the stop valve body 100. A first annular boss 21 is provided on the inner side wall of the male connector body 200 toward the center. The interface of the stop valve body 100 can be connected by flange, welding, or threaded connection. During design, the male connector body 200 is pre-connected and fixed to the stop valve body 100 to form an integral body.
[0043] The slide 300 is located in the male connector body 200. An annular protrusion 31 is radially protruded outward on the outer wall of the slide 300. The protrusion 31 is axially slidable along the male connector body 200. A plurality of first through holes 32 are axially penetrated on the protrusion 31. When the protrusion 31 abuts against the first boss 21, one end of the slide 300 is sealed and penetrated in the first boss 21. The first through hole 32 is used for the passage of gas or liquid. The slide 300 can slide within the male connector body 200 in a limited manner, and its stop position can determine the connection and closure between the male connector body 200 and the outside.
[0044] The first spring 22 has two ends respectively abutting against the port of the male connector body 200 and the protrusion 31; the first spring 22 is compressed and disposed within the male connector body 200 to push the slide 300 so that the slide 300 can be stably positioned in two positions: connecting the male connector body 200 with the outside and closing it;
[0045] The female connector body 400 has one end detachably fixed to the other end of the male connector body 200 via a connecting piece. An annular second boss 41 is radially inwardly projecting from the inner sidewall of the female connector body 400. A plurality of second through-holes 42 are axially formed through the second boss 41. The second through-holes 42 are used for the passage of gas or liquid. The overall axial length of the male connector body 200 and the female connector body 400 can be varied by adjusting the connection position of the connecting piece.
[0046] A sliding sleeve 500 is axially and sealingly slidably disposed within the female connector body 400 . One end of the sliding sleeve 500 abuts against the first boss 21 . The sliding sleeve 500 can slide relative to the female connector body 400 to adjust its position.
[0047] The shaft core 600 is slidably inserted into the sliding sleeve 500. One end of the shaft core 600 is fixed to the second boss 41, and the other end is provided with a clamping head 61. The clamping head 61 abuts against the sliding seat 300. When one end of the sliding seat 300 is sealingly inserted into the first boss 21, the clamping head 61 is sealingly clamped to the sliding sleeve 500. When the sliding seat 300 is separated from the first boss 21, the clamping head 61 is separated from the sliding sleeve 500 and extends into the male connector body 200, and the male connector body 200 is connected to the sliding sleeve 500.
[0048] The second spring 43 has two ends respectively abutting against the other end of the sliding sleeve 500 and the second boss 41;
[0049] The welding pipe nut 700 has one end which is detachably connected to the other end of the female connector body 400 , and the other end which is used for welding pipe connection with the pipeline 71 .
[0050] Specifically, when the distance between the male connector body 200 (first boss 21) and the female connector body 400 (second boss 41) is a first distance value, the slide 300 is sealed and penetrated in the first boss 21, and the clamp 61 is sealed and clamped on the sleeve 500. At this time, the male connector body 200 and the female connector body 400 are closed and not connected; when the distance between the male connector body 200 (first boss 21) and the female connector body 400 (second boss 41) is a second distance value (the second distance value is less than the first distance value), the female connector body 400 continues to receive a section of the sleeve 500 into its interior, and the shaft core 600 moves a certain distance relative to the sleeve 500 toward the male connector body 200, thereby pushing the slide 300 to move a certain distance away from the first boss 21. At this time, the slide 300 disengages from the first boss 21, the clamp 61 disengages from the sleeve 500 and extends into the male connector body 200, and the male connector body 200 is connected with the female connector body 400.
[0051] In the above technical solution, before the female connector body 400 is connected to the male connector body 200 by using the connecting piece, the initial position of the slide 300 in the male connector body 200 is: under the thrust of the first spring 22, it is sealed and penetrated into the first boss 21, and the male connector body 200 is in a sealed state; the initial position of the sliding sleeve 500 in the female connector body 400 is: under the thrust of the second spring 43, the sliding sleeve 500 slides away from the second boss 41 until its end is in sealing contact with the clamping head 61 on the shaft core 600, and the female connector body 400 is also in a sealed state;
[0052] Then, when the female connector body 400 and the male connector body 200 are connected by the connecting piece, the connecting piece drives the female connector body 400 to move a certain distance toward the male connector body 200. At this time, the clamping head 61 contacts the sliding seat 300, and the sliding sleeve 500 contacts the first boss 21. The distance between the male connector body 200 (first boss 21) and the female connector body 400 (second boss 41) is the first distance value, and the male connector body 200 and the female connector body 400 still maintain their respective sealing states.
[0053] After the connecting piece drives the female connector body 400 to continue moving toward the male connector body 200 for a certain distance, at this time, the sleeve 500 slides and extends into the female connector body 400 for a certain distance, the clamping head 61 completely disengages from the sleeve 500 interface and extends into the male connector body 200 for a certain distance, and the sliding seat 300 compresses the first spring 22 under the pushing action of the clamping head 61 to completely disengage from the first boss 21. The distance between the male connector body 200 (first boss 21) and the female connector body 400 (second boss 41) is the second distance value, and the male connector body 200 is connected to the female connector body 400.
[0054] The male connector body 200 is pre-fixed to one end of the shutoff valve body 100. The other end of the shutoff valve body 100 is welded and secured to the main unit pipeline. The weld nut 700 on the female connector body 400 is welded to the indoor unit. The female connector body 400 is connected to the male connector body 200 via a connector. When the distance between the male connector body 200 (first boss 21) and the female connector body 400 (second boss 41) reaches the second distance value, the male connector body 200 and the female connector body 400 are connected, and the indoor and outdoor / machine pipe cavities are connected. When disassembled, they are self-sealed. The integrated quick-connect shutoff valve retains the original shutoff valve structure and function, adding a self-sealing structure and a connection locking mechanism to the female connector body 400. The first spring 22 (stainless steel spring) internally presses against the slide 300. During the entire process of installing and removing the female connector body 400, the refrigerant or heating agent is in a completely sealed state inside, with no leakage possible; the integrated quick connector stop valve makes installation and use safe and maintenance convenient, without the need for professional technicians and professional tools.
[0055] In another technical solution, an annular first groove is defined on the outer wall of the interface of the stop valve body 100. A first sealing ring 11 is tightened onto the first groove. Threads are provided on the outer wall of the interface of the stop valve body 100, adjacent to the first groove. The inner wall of the port of the male connector body 200 is threaded. This port of the male connector body 200 is threadedly sleeved onto the interface of the stop valve body 100, with the inner wall pressing against the first sealing ring 11. Through the threaded connection, the first sealing ring 11, and the first groove, the male connector body 200 can be quickly connected to the stop valve body 100, creating a good seal at the connection, preventing leakage of refrigerant or heating agent.
[0056] In another technical solution, the spring wire diameter of the first spring 22 is smaller than the wall thickness of the interface of the stop valve body 100, and the inner diameter of the first spring 22 is larger than the inner diameter of the interface of the stop valve body 100;
[0057] The sidewall of the slide 300, the end wall of the protrusion 31 facing one end of the first spring 22, and the inner sidewall of the male connector body 200 form an annular first retaining groove 33. One end of the first spring 22 is retained in the first retaining groove 33. This allows the first spring 22 to be stably retained in the male connector body 200, providing a stable thrust for the slide 300, thereby maintaining the slide 300 in a desired position.
[0058] In another technical solution, a second groove is radially defined on the sidewall of the slider 300 at the end facing the first boss 21. A second sealing ring 34 is tightly fitted over the second groove. When the end wall of the projection 31 abuts the end wall of the first boss 21, the outer wall of the second sealing ring 34 abuts the inner wall of the first boss 21. In a self-sealing state, the second groove and second sealing ring 34 ensure a stable seal between the slider 300 and the first boss 21, preventing leakage of refrigerant or heating agent.
[0059] In another technical solution, the connecting member is a sliding nut 800, and a thread is provided on the outer wall of the interface at the other end of the male connector body 200, and a thread is provided on the inner wall of one end of the sliding nut 800, and the sliding nut 800 is screwed onto the interface at the other end of the male connector body 200; by controlling the number of overlapping threads between the sliding nut 800 and the male connector body 200 when screwed together, the distance between the male connector body 200 (first boss 21) and the female connector body 400 (second boss 41) is controlled, thereby accurately controlling the closed and connected states between the male connector body 200 and the female connector body 400.
[0060] The port at the other end of the sliding nut 800 is provided with a first annular retaining ring 81 protruding radially inward, and the port at one end of the female connector body 400 is provided with a second annular retaining ring 44 protruding radially outward. The first retaining ring 81 is slidably sleeved on the outer wall of the sliding nut 800 and is tightened and abutted against the second retaining ring 44. When the sliding nut 800 is rotated, the female connector body 400 will not rotate but will only move radially, thereby not affecting the pipe 71 connected to the weld pipe nut 700. Through the arrangement of the first retaining ring 81, the second retaining ring 44 and the second spring 43, the first retaining ring 81 and the second retaining ring 44 can be tightened and abutted against each other, so that the female connector body 400 can move axially synchronously with the sliding nut 800.
[0061] An annular retaining ring 45 is protruding outward from the outer wall of the female connector body 400. The outer diameter of the retaining ring 45 is larger than the inner diameter of the sliding nut 800. The retaining ring 45 prevents the sliding nut 800 from being separated from the female connector body 400 when not connected to the male connector body 200, thus preventing it from being lost.
[0062] In the above technical solution, the male connector body 200 and the female quick-connect body are locked together using a flexible joint with internal and external threads. This allows users to install, repair, and add refrigerant or heating agent using a common open-end wrench, without the need for specialized technicians or tools. The integrated quick-connect shut-off valve of the present invention is safe, convenient, and easy to install and repair.
[0063] In another technical solution, an annular third groove is provided on the inner side wall of the other end of the male connector body 200, and a third sealing ring 23 is clamped on the third groove. The outer side wall of the sleeve 500 facing one end of the male connector body 200 abuts against the inner side wall of the third sealing ring 23. The setting of the third groove and the third sealing ring 23 can ensure a stable seal at the connection between the sleeve 500 and the male connector body 200 to prevent leakage of refrigerant or heating agent.
[0064] The outer wall of the sliding sleeve 500 is provided with a plurality of annular fourth grooves at intervals. A fourth sealing ring 51 is provided to compress the fourth grooves. The outer wall of the fourth sealing ring 51 abuts against the inner wall of the female connector body 400. The provision of the plurality of fourth grooves and the fourth sealing ring 51 ensures a sealed sliding connection between the sliding sleeve 500 and the female connector body 400, preventing leakage of refrigerant or heating agent.
[0065] In another technical solution, the chuck 61 is truncated cone-shaped, and the end of the chuck 61 facing the slide 300 is larger than the end facing the sleeve 500. An annular fifth groove is provided on the outer wall of the chuck 61, and a fifth sealing ring 62 is provided on the tightening sleeve of the fifth groove. The port of the sleeve 500 facing the male connector body 200 is truncated cone-shaped, and the end facing the male connector body 200 is larger than the end facing the second spring 43. When one end of the slide 300 is sealed in the first boss 21, the chuck 61 is clamped on the interface of the sleeve 500, and the outer wall of the fifth sealing ring 62 abuts against the inner wall of the sleeve 500. The setting of the fifth groove and the fifth sealing ring 62 can ensure a stable seal between the clamp head 61 and the port of the sleeve 500, thereby preventing leakage of refrigerant or heating agent; the truncated cone-shaped setting of the clamp head 61 and the port of the sleeve 500 can prevent the sleeve 500 from being separated from the female connector body 400 and the shaft core 600 and lost after the female connector is removed.
[0066] In another technical solution, an annular notch is formed on the end wall of the sliding sleeve 500 facing one end of the second spring 43. This notch and the inner sidewall of the female connector body 400 form an annular second retaining groove 52, and one end of the second spring 43 is retained in the second retaining groove 52. This allows the second spring 43 to be stably retained between the sliding sleeve 500 and the second boss 41, providing a stable thrust force for the sliding sleeve 500, thereby maintaining the sliding sleeve 500 in a desired position.
[0067] In another technical solution, an annular third groove is provided on the outer side wall of the other end of the shaft core 600, and the third groove is engaged with the second boss 41;
[0068] An annular rubber pad 63 is tightened against the third slot. The end wall of the rubber pad 63 abuts the end wall of the second boss 41 facing away from the second spring 43. The axial projection of the rubber pad 63 does not overlap with the axial projection of the second through hole 42. This ensures a stable fixation between the second boss 41 and the shaft core 600, preventing any shaking and preventing fluid from being affected by the fluid passing through the second through hole 42.
[0069] In another technical solution, a threaded hole is provided on the outer side wall of the port at the other end of the female connector body 400, and an annular sixth groove is provided on the outer side wall adjacent to the outermost threaded hole. An annular sixth sealing ring 46 is pressed and sleeved on the sixth groove.
[0070] The inner sidewall of the port at one end of the pipe nut 700 is threaded, and an annular third boss 72 is radially inwardly projecting near the innermost thread. The pipe nut 700 is threadedly connected to the other end of the female connector body 400. The outer sidewall of the sixth sealing ring 46 abuts the inner sidewall of the pipe nut 700, and the end wall of the port of the female connector body 400 abuts the end wall of the third boss 72. The provision of the sixth groove, the sixth sealing ring 46, and the third boss 72 ensures a stable seal at the connection between the female connector body 400 and the pipe nut 700, preventing leakage of refrigerant or heating agent.
