Vacuum pressure relief working principle of the pneumatic valve 2

pneumatic vacuum safety valve spring and the two kinds big. Also has the impulse safety pneumatic valve, pneumatic valve, pilot operated safety security pneumatic valve switch, safe release of the pneumatic valve, pneumatic valve and other static weight safely. Spring type pneumatic valve spring force and safety rely mainly on work, in a closed pneumatic valve spring type safety, rather than closed, generally inflammable, explosive or toxic medium should choose enclosed, steam or inert gas, can choose not closed type, pneumatic valve with a wrench and a security not to bring a wrench spring. Wrench the flexibility of the key is to check the CD, sometimes can also be used for emergency relief for the manual.
security work safety system of pneumatic valve. When the system pressure exceeds the set value, pneumatic valve open part of d. gases into the atmosphere system, the system pressure shall not exceed the allowable values, so as to ensure that the system is accidentally due to excessive stress. Safety pneumatic valve is also called the overflow valve. Pneumatic valve icon of some typical structure safety. The figure for a pneumatic piston type safety valve, pneumatic valve core is a unit. Air pressure on the piston. A, when pressure exceeds the TVC of the spring force to determine the piston open A is compressed air, the part of the atmosphere through the pneumatic valve port, when air pressure below the TVC, spring driving the piston down, close the pneumatic valve.
