oxygen valve air nitrogen cylinder valveProduct Information:1. In
order to ensure the safety of use, it is stipulated that the outlet
spiral direction of gas cylinder valve should use left screw thread
for combustible gas and right screw thread for non-combustible
gas.2. Cylinder valves of different media are generally used in
different structures. Their common characteristics are mostly
manual, simple structure, small size, high strength,3, 200bar
cylinder valve: working pressure: 200bar; Test pressure: 300bar,
working temperature in -40~60ºC, material can adapt to the physical
and chemical characteristics of the medium and commonly used
copper, some with safety discharge device.4, cylinder valve
according to the structure is divided into axial type, flap type,
needle form, rubber connection type and diaphragm type. Their range
of action is the pressure range for compressed gas and the
temperature range for liquefied gas.5, oxygen and strong oxidation
gas cylinder valve sealing materials, liquefied petroleum cylinder
valve handwheel must be used flame retardant materials. The main
performance test items before delivery are air tightness test,
safety device action test;6, in the shape and identification before
the valve body strength test and opening torque, opening range,
vibration resistance, resistance to humidity, high temperature (or
low temperature) and vacuum test.7, 200bar common valve models:
