Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an automotive air conditioning anti-leakage valve body. Background Technology

[0002] The high-pressure relief valve of an automotive air conditioning system is a protective device that is usually installed near the high-pressure pipe of the compressor. Its main function is to regulate the pressure in the air conditioning system to protect the normal operation of the air conditioning system.

[0003] When the car condenser fails to dissipate heat properly, it can cause the compressor pressure to become too high. In this case, the pressure relief valve opens under the pressure to release the pressure. However, during this process, some refrigerant is easily discharged. After the pressure drops, the reduction in refrigerant may cause the compressor to operate under high load for a long time, affecting the compressor's lifespan. In addition, excessive discharge of refrigerant can also affect the air conditioning's cooling effect, making it impossible for the car interior to reach the ideal cool temperature. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-leakage valve body for automotive air conditioning to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive air conditioning leak-proof valve body, comprising a pressure relief valve body, and further comprising: A separation section is installed on the top of the pressure relief valve body and separates gas and liquid during pressure relief. The separation section includes a hollow part fused to the top of the pressure relief valve body, a cover assembly installed on the top of the hollow part, and a through groove and a storage groove opened inside the hollow part. The through groove and the storage groove are connected. The cover assembly seals the top of the hollow part when no gas is discharged. A sealing part is installed inside a hollow component and rises and falls with pressure. The sealing part includes a lifting component and an extension fused to the bottom of the lifting component. The lifting component moves up and down inside the hollow component and can block the through groove. A spring is fixedly connected between the lifting component and the hollow component. A blocking component that seals the top of the pressure relief valve body is fused to the bottom of the extension component.

[0006] Preferably, the covering group includes: The support component is welded inside the hollow component; Moving parts, sliding through support parts; The counterweight and the sealing element are designed in a ring shape and are respectively fused to both ends of the moving part.

[0007] Preferably, the top of the storage tank is fixedly connected to a partition that changes the airflow direction, and the bottom of the partition is arc-shaped.

[0008] Preferably, the hollow component has sliding grooves on both sides of its inner wall, and the lifting component has sliding components fixedly connected to both sides of its surface, with the surface of the sliding components slidably connected to the inner wall of the sliding grooves.

[0009] Preferably, the sealing part further includes a bracket, which is fixedly sleeved on the surface of the extension member, and a sealing member is sleeved on the surface of the bracket. The sealing member controls the airflow after being raised inside the hollow member.

[0010] Preferably, a limiting member is fixedly sleeved on the surface of the closure member, and a groove and a slot are formed on the inner wall of the hollow member. The surface of the limiting member is slidably connected to the inner wall of the groove, and the surface of the closure member is in contact with the inner wall of the slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention separates the refrigerant during pressure relief, allowing gas to escape and achieving the pressure relief effect. The refrigerant remains in the lower part of the storage tank. When the pressure decreases, the sealing part descends, releasing the obstruction of the refrigerant. The refrigerant then flows back through the drain hole at the top of the sealing part, thereby reducing refrigerant leakage. This solves the problem that in some current automotive air conditioning compressors, the refrigerant easily leaks out along with the air when the pressure relief valve is venting, which can affect the normal operation of the compressor.

Detailed Implementation

[0014] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6As shown, an automotive air conditioning anti-leakage valve body includes a pressure relief valve body 100. A vent hole is penetrating the top of the pressure relief valve body 100. The pressure relief valve body 100 is installed on the automotive air conditioning compressor. When the internal pressure of the compressor is high, excess gas can be discharged through the vent hole. A separation part 200 is installed on the top of the pressure relief valve body 100. The separation part 200 includes a hollow component 210 fused to the pressure relief valve body 100. A through groove 220 and a storage groove 230 are formed inside the hollow component 210. The storage groove 230 communicates with the interior of the hollow component 210 through the through groove 220. Gas discharged from the exhaust pipe can be discharged into the storage groove 230 through the through groove 220. When the pressure is too high, some refrigerant is discharged into the storage groove 230 along with the gas. Separated from the refrigerant, the refrigerant flows back into the hollow component 210 through the lower part of the storage tank 230 and is discharged back into the pressure relief valve body 100. The gas is discharged through the hollow component 210. A cover assembly 240 is installed on the top of the hollow component 210. The cover assembly 240 can seal the top of the hollow component 210 when there is no fusion discharge. The cover assembly 240 includes a support member 241 fused inside the hollow component 210. A movable member 242 slides through the top of the support member 241. A counterweight 244 is fused to the bottom of the movable member 242. A sealing member 243 is fused to the top of the movable member 242. The sealing member 243 has a ring structure. When the gas needs to be discharged, the sealing member 243 is lifted by force and drives the counterweight 244 to be lifted through the movable member 242. After that, under gravity... Under the action of the counterweight 244, the moving part 242 pulls the sealing part 243 down, and the sealing part 243 re-seals the top of the hollow part 210. The top of the storage tank 230 is fixedly connected to the partition 300. The bottom of the partition 300 is arc-shaped. When the airflow passes through the storage tank 230 and is discharged into the storage tank 230, it first flows downward with the partition 300. At this time, the refrigerant can flow downward at an angle, and the gas flows upward and lifts the sealing part 243 to be discharged to the outside. The bottom of the inner wall of the storage tank 230 is inclined so that the refrigerant can flow downward at an angle. The hollow part 210 is equipped with a sealing part 400 that rises with the increase of pressure. The sealing part 400 includes a lifting part 410 that moves up and down above the inner wall of the hollow part 210. A spring 420 is fixedly connected to the top of component 410. One end of the spring 420 is fixedly connected to the top of the inner wall of hollow component 210. An extension 430 is fused to the bottom of lifting component 410, and a blocking component 440 is fused to the bottom of extension 430. Under normal conditions, the blocking component 440 can block the top of the exhaust port of the pressure relief valve body 100. At the same time, lifting component 410 blocks through groove 220. Sliding grooves are provided on both sides of the inner wall of hollow component 210. Sliding components 450 are fixedly connected to both sides of the surface of lifting component 410. The surface of sliding component 450 is slidably connected to the inner wall of the sliding groove, thereby limiting the lifting height of lifting component 410. A bracket 460 is fixedly sleeved on the surface of extension 430, and a closing component 470 is sleeved on the surface of bracket 460.The closure 470, raised inside the hollow component 210, can block the lower opening of the storage slot 230, controlling the gas flow direction. A limiting member 500 is fixedly fitted onto the surface of the closure 470. The inner wall of the hollow component 210 has a groove 480 and a slot 490. The surface of the limiting member 500 slides against the inner wall of the groove 480. The limiting member 500, in conjunction with the groove 480, restricts the movement range of the closure 470. The top of the inner wall of the closure 470 is designed to be higher around the edges and lower in the middle. After the closure 470 is raised, its surface fits against the inner wall of the slot 490, ensuring a sealing effect and a proper gas flow path.

[0016] Working principle: When the internal pressure of the air compressor is too high, the gas is discharged into the hollow component 210 through the exhaust port. The gas first pushes open the blocking component 440, and the extension component 430 then drives the lifting component 410 and the sealing component 470 to rise. The sealing component 470 seals the opening at the bottom of the storage tank 230, and the lifting component 410 releases the blockage of the through channel 220. The air flows upward and is discharged into the storage tank 230 through the through channel 220. The separator 300 obstructs the airflow and guides the air to flow downward first. At this time, the refrigerant discharged with the air separates from the gas and remains in the storage tank 230. Inside, the upward flow of gas causes the seal 243 to rise, and the gas is then discharged, thus achieving the pressure reduction effect. After the gas is discharged, the internal pressure of the hollow part 210 decreases. Under the action of gravity, the seal 243 re-seals the top of the pressure relief valve body 100. Under the action of the spring 420, the lifting part 410 drives the blocking part 440 and the sealing part 470 to descend through the extension part 430. The refrigerant inside the storage tank 230 flows into the hollow part 210. The top of the blocking part 440 has a drain hole, through which the refrigerant flows back into the pressure relief valve body 100.
