Cock and working principle of the pneumatic valve USES

how it works:
with hole plug body as a pneumatic valve opening and closing. Plug with pneumatic valve rod rotation, in order to realize the opening and closing action. Small cock without packing pneumatic valve is also known as ''. More than cock pneumatic valve plug body for cone ( There are also the cylinder) , cooperate with pneumatic valve cone hole surface of sealing pair. Cock pneumatic valve is to use one of the first pneumatic valve, simple structure, switch quickly, fluid resistance is small. Ordinary cock pneumatic valve on finishing the metal plug body and direct contact between the pneumatic valve to seal, so the sealing is poorer, opening and closing force is big, easy to wear and tear, usually can only be used for low ( Is not higher than mpa) And small diameter ( Less than mm) The occasion.
application:
cock pneumatic valve widely used in oil field exploitation, transportation and refining equipment, but also widely used in petrochemical industry, chemical industry, coal gas, natural gas, liquefied petroleum gas, hvac industry and general industry.
