Description

Technical Field

[0001] The present application relates to the technical field of air-conditioning stop valves, and in particular to an air-conditioning stop valve that is easy to install. Background Art

[0002] The air conditioning stop valve is a device that controls the flow of refrigerant in the air conditioning system. It is usually installed on the connection port of the gas pipe and liquid pipe of the outdoor unit of the split-type household air conditioner. Its working principle is to control the passage and cutoff of the refrigerant by manually controlling the opening and closing of the valve core. When the air conditioning system is running, the refrigerant is compressed into high-temperature and high-pressure gas by the compressor, and then dissipated and cooled by the condenser to become a high-pressure liquid. The high-pressure liquid enters the stop valve through the pipeline. When the refrigerant enters the valve, the pressure difference will cause the valve to close, preventing the refrigerant from continuing to flow, thereby stopping the circulation of the refrigerant.

[0003] The existing Chinese patent with publication number CN216479229U discloses a closed air-conditioning stop valve, including a stop valve body, a copper tube fixedly connected to the bottom of the stop valve body, and pipes fixedly connected to both sides of the stop valve body, a handwheel disk fixedly connected to one end of the pipe, a reinforcement mechanism connected between the stop valve body and the pipe, four limit grooves are provided on the outer annular surface of the handwheel disk, and an anti-slip mechanism is provided on the outer sleeve of the handwheel disk, the anti-slip mechanism includes an anti-slip strip, a second bolt, a grip ring and a limit block, eight anti-slip strips are fixedly connected to the outer annular surface of the grip ring, a second bolt is connected between the grip ring and the handwheel disk, and four limit blocks are fixedly connected to the inner wall of the grip ring at equal distances.

[0004] The above-mentioned closed air conditioning stop valve can increase the connection stability between the stop valve body and the pipeline through the reinforcement mechanism, prevent the two from breaking and being damaged after being stressed, ensure the normal use of the two, and extend the service life of the two. However, the above-mentioned closed air conditioning stop valve still has some disadvantages, such as: the copper pipe is fixedly connected to the stop valve body, when the copper pipe is damaged, it is not easy to remove the copper pipe from the stop valve body, and it is not convenient to reinstall a new copper pipe on the stop valve body, which needs to be improved. Utility Model Content

In this way, the rotating plate and the clamping block are moved into the first boss, providing space for the threaded connection of the connecting pipe.

[0014] Optionally, the valve body is provided with a thread groove for cooperating with the connecting pipe thread, and when the connecting pipe abuts against the inner wall of the thread groove, the first rotation groove corresponds to the second rotation groove, and the first yield groove corresponds to the second yield groove.
