The gas valve is a novel safety matching device for gas pipeline engineering. The valve is used for cutting off, connecting and regulating the gas in the pipeline, and has good control characteristics and closing sealing performance. It is suitable for various gas medium pipelines such as city gas, liquefied petroleum gas, natural gas, oxygen, etc.
The gas valve has wide application and various classification methods. The general categories can be divided into two broad categories:

Second type of driving valve: the valve is operated by manual, electric or pneumatic operation. Such as gate valves, shut-off valves, throttle valves, butterfly valves, ball valves, plug valves, etc.
Triangle valve
At present, two methods for detecting the air tightness of a motor valve of a gas meter producer are mainly adopted, a first air pressure difference detection method is mainly characterized in that a standard part and a detection part are selected and fixed, air is simultaneously introduced into the standard part and the detection part, and whether the air tightness of the detection part is qualified is judged through the change of the air pressure difference between the standard part and the detection part; the second hydraulic bubble leaching method is mainly to seal two ends of a detection piece, place the detection piece in water and observe whether bubbles emerge.
The traditional valve air tightness detection mode is not strict, the detection error is larger, the motor valve air tightness can not be visually displayed and detected, the product quality is difficult to accurately judge, and the reliability of the obtained conclusion is low. The second hydraulic bubble leaching method also needs to clean the valve after detection, has complex working procedures and is unfavorable for quick development. The two-way airtight detection equipment is common, and the three-way right-angle valve airtight detection machine is difficult to realize the function of automatically ejecting qualified products.
On the basis, we design an automatic detection device which can automatically clamp a triangular valve, automatically charge and detect, and can display the pressure of the charging gas, but the gas which is used for detecting the air tightness by pouring in is used for ejecting qualified products so as to distinguish the leakage products, so that how to save energy is the design cost, and how to facilitate operation, reduce working procedures and the like is the initial aim of research and development.

The valve table 61 can be replaced generally, and because the triangular valves with different specifications are different in positioning points, the diameters of the positioning rings are different, and the valve table 61 needs to be replaced conveniently when detecting the triangular valves with the same specification, so that the efficiency is better, and the sealing performance of the two ends of the valve table can be ensured after the valve table is positioned accurately.
The automatic push-out mechanism 7 is arranged on the vertical surface of the operation table 2, is positioned between the valve seat 6 and the inflating head 5 in the vertical direction, and after the triangular valve is placed on the valve seat 6 through the positioning ring 60, the inflating hole of the triangular valve is opposite to one valve port of the triangular valve, and the automatic push-out mechanism 7 faces to the other valve port of the triangular valve.
