Valve气阀
Reciprocating compressors generally use one of three types of valve configurations:
Tangent Ring切线环
The tangent ring is cut into three segments so that each cut lies on the side of an
equilateral triangle. The cuts of this ring maintain sealing contact regardless of
variations of the ring’s inside diameter. If wear occurs in the tangent ring, the
garter spring will tighten the ring segments to compensate for the wear.
The connecting rod is made up of forged steel for 150 kW (200 hp) reciprocating
compressor. For compressor less than or equal to 150kW, ductile iron material is
used.
Rod Packing活塞杆填料
Rod packing is required to prevent the gas leakage along the piston rod where it
passes through the crank end cylinder closure.
Cross Head十字头
All industrial compressors are equipped with crosshead. The crosshead is used to
guide the piston in the cylinder bore. The following are the advantage of the crosshead.
Compartments in the distance piece collect and control packing leakage when the gas is toxic or flammable. The leakage can be direct to a flare or buffer inert gas is used to prevent the toxic gas leakage to the atmosphere.
