Blocking valve structure Description:
1, the valve is welded, straight channel without shrinking, single
plane seal, valve sealing surface heap austenitic stainless steel, block
plate with O-shaped rubber seal.
2, the use of self-tight cavity pressure seal structure, hydraulic
test or operation, can be sealed by the medium pressure to achieve a
reliable seal, and the higher the pressure, the more reliable the seal.
3, the valve body is made of high quality cast steel, both ends
processed into U-groove and pipe directly butt welding, chemical
composition and properties of the two materials are similar, excellent
welding performance, without intermediate welding transition section;
four open-loop 38CrMoAlA corrosion Nitriding, to ensure that its
heat-resistant, and wear-resistant, corrosion-resistant,
scratch-resistant, easy disassembly; cavity self-sealing gaskets, high
temperature steam corrugated asbestos gaskets, 18-8 wire braided
internal enhancements to ensure that the seal, Extend the service life;
sealing surface surfacing 1Cr18Ni9Ti, rust, erosion, repeated tests can
still guarantee the seal.
