Oxygen use method and principle of the pneumatic valve 1

some special vacuum pneumatic valve and the use of special connection between the cylinder. Adopt left thread, such as hydrogen and propane use method and matters needing attention of the reduced pressure pneumatic valve and oxygen pneumatic valve is basically the same. But should also be pointed out that: special vacuum pneumatic valve is generally not used in other gases. In order to prevent misuse. Also called reverse thread, should pay special attention to when the device.
often need oxygen, nitrogen, hydrogen and argon gas, etc. These gases are generally stored in a dedicated high-pressure gas cylinders. When used by reduced pressure pneumatic valve gas pressure drop to experiment the required range, oxygen pneumatic valve in the physical chemistry experiments. After fine tuning other pneumatic control valve, make the gas input using the system. The most commonly used pneumatic valve, pneumatic valve as oxygen pressure oxygen or oxygen table.

the use of a pneumatic valve, oxygen method
oxygen pressure pneumatic valve has many specifications. The highest inlet pressure, mostly by use of different requirements. The minimum inlet pressure of not less than the inlet pressure. Times. Inlet pressure and specifications, as commonly, the highest inlet pressure.
screw the nut on the two perfectly match. Device, therefore, when vacuum pneumatic valve shall determine whether the connection specification is consistent with the sub cylinder and use the system. Pneumatic valve and cylinder connected by hemispherical surface. When using, should stick to the two hemispheres surface is bright and clean, in order to ensure a good airtight effect. High-pressure gas blowing dust device before available. When necessary, can be materials such as ptfe gasket.
in order to avoid fire accidents. Oxygen pneumatic valve should be forbidden contact with grease.
pressure-relief residual air in the pneumatic valve should be put the net, to stop work. Then loosen the adjusting screw to avoid compression of durable components elastic deformation.
not in contact with corrosive substances. Oxygen pneumatic valve should prevent the impact vibration.
2, oxygen, the working principle of pneumatic valves
low pressure chamber for gas exports, pneumatic valve of high-pressure oxygen chamber connected to the cylinder. And to use the system. High pressure table for the cylinder value for the pressure of the gas storage. The low pressure table entry pressure can be controlled by the adjusting screw.
then clockwise (low pressure gauge pressure adjustment screw, when used to open the main switch. The compressed main spring and transmission film, spring block and ejector and open the valve. Such imports of high-pressure gas by the high pressure chamber after the throttle pressure into the low pressure chamber, and the entrance to the working system. Turn the adjusting screw, change the height of the valve to open, so as to regulate the amount of by high pressure gas and achieve the required pressure value.
is also reduced pressure pneumatic valve malfunction signal device. If the valve pad, damage to the valve, or due to other reasons, oxygen pneumatic valves are equipped with pneumatic valve. Maintenance reduced pressure pneumatic valve and the safe use of devices. Cause the inlet pressure to rise and beyond a certain permission value, pneumatic valve will automatically open the exhaust.
gas reduced pressure pneumatic valve 3 and other oxygen pneumatic valves.
