Description

Technical Field

[0001] The invention relates to the technical field of compressors, in particular to a gas valve thrust stop device equipped with an ultrasonic probe. Background Art

[0002] The gas valve is a component used in the compressor to control the flow of gas into and out of the cylinder. It is mainly composed of a valve seat, a valve plate, a spring and a lift limiter. The lift height or closure between the valve plate and the valve seat determines the size and tightness of the gas channel. The spring is mainly used to push the valve plate to close, and can also reduce the impact of the valve plate and the lift limiter when the valve plate is opened. The lift limiter can limit the lift of the valve plate and support the spring; the opening and closing of the valve plate of the gas valve is controlled by the pressure difference between the gas inside and outside the cylinder and the spring force, and no other driving mechanism is required, so it is called an automatic valve.

[0003] However, during daily use, the internal connectors of the gas valve will wear out over time. However, the interior of the gas valve is not easy to observe, so it is impossible to accurately know the internal wear and tear, and thus it is impossible to maintain and replace it in time, resulting in damage and scrapping, which in turn has a certain impact on other equipment, which is very troublesome.
