1. Appearance pneumatic actuator check. The valve surface should be free of defects and cracks, and the valve body has no bursting phenomenon;
2. Valve tightness test. In the case of the valve closed, the level gauge does not leak under the test pressure of 1.1 MPa, and the pressure gauge has no pressure drop. It is required that the two sides of the valve are under pressure and separately tested, and the same effect is achieved by multiple opening and closing; 3. The operation flexibility of the valve. In the case of a single person opening and closing the valve multiple times, the flame arrester is still flexible and light. Detection medium: characteristics of equipment such as water, air, nitrogen, etc. 1. It is equipped with automatic gas booster pump for imported gas, which can easily realize adjustable and controllable output pressure. 2. Advanced technology and reasonable structural design. It has the characteristics of small size, light weight and beautiful appearance.
3. All pressure-bearing parts adopt standard parts of international famous brands, without any welding connection, easy to disassemble, high safety factor, long service life and easy maintenance.
