First, the main performance specifications of SCZ series plug-in valve
Note: The rubber grade depends on the nature of the medium and the use temperature.
The material grade of the ram depends on the nature of the medium.
Second, SCZ series plug-in valve housing test and seal test
1. The shell test and sealing test medium of the plug-in valve is water (containing preservatives), kerosene or other suitable liquids with a viscosity not greater than water.
2. The sealing pair is a non-metal sealed plug-in valve. The test and requirements of the sealed housing are in accordance with GB / T13927-92 Class D regulations.
3. The sealing pair is a metal-sealed plug-in valve. For those with sealing performance requirements, the leakage of the sealing test is calculated according to 1 ¡Á DNmm3 / s.
4. The plug-in valve driven by electric, hydraulic and pneumatic devices, after the closed position is adjusted, close 3 times and carry out the shell and seal test according to the requirements of 1 and 3.
5. The cleanliness requirements of the plug-in valve are in accordance with the provisions of JB / T7748.
6. Static pressure life test.
7. The number of static pressure life tests of the plug-in valve is in accordance with regulations, and other technologies shall be in accordance with the regulations in JB / Z 234.
Note: 1. Metal sealing means that the sealing sub-material is metal-metal
2. Non-metallic sealing means that the sealing sub-material is metal-nonmetal or nonmetal-nonmetal.
