Description:
Performance requirements:
1 opening and closing torque, under the nominal pressure, the valve opening and closing the
required maximum torque should not exceed 6Nm
2 air tightness, under the nominal pressure of 1.1 times, the valve is closed and any open state
should be no leakage.
3 vibration resistance, under the nominal pressure, the valve should be able to withstand the
amplitude of 2mm, frequency of 33 Hz 1/3 vibration, the valve on the threaded connection should
not loose, there is no leakage.
4 temperature resistance, under the nominal pressure, the use of the area of the valve temperature
is divided into: general area of -20~60 degrees Celsius. In the allowable temperature range,
should not leak.
5 pressure resistance, in 1.6 times the nominal pressure line, the valve should be no leakage
and other anomalies.
6 durability, under the nominal pressure, the valve structure for the diaphragm structure, the
whole trip open and close 1000 times, the other structure of the valve full stroke open and close
4000 times, there should be no leakage and other anomalies.
7.safety device action, the safety device should be in the range of 1.2-1.5 times the nominal
pressure action.
