Briefly describes the guide type safety performance of the pneumatic valve

the guide type safety pneumatic valve is a safety protection with pneumatic valve, under the action of the open-close part affected by external forces in a normally closed state, when the equipment or piping within the medium pressure increases, more than a specified value automatically when open, through a discharge medium system to prevent the pipeline or equipment within the medium pressure in excess of the prescribed value.
the guide type safety pneumatic valve, the form of the structure is divided into vertical hammer, lever, spring type and leading type ( Pulse type; According to the pneumatic valve body structure, can be divided into two kinds of, closed and not closed. Closed-end security pneumatic valve is not leaking out medium, all along the discharge to the designated location, commonly used in toxic and corrosive medium. For air and steam safety pneumatic valve, pneumatic valve use not enclosed more safety. For the selection of safe pneumatic valve products, should according to the actual seal pressure to determine. Pneumatic valve for spring type safety, in a nominal pressure ( PN range, has several work stress level of spring, when placing order, in addition to indicate safety pneumatic valve model, name, medium and temperature, still should indicate the pneumatic valve sealing pressure, or else the maximum sealing pressure supply.
