Karakteristik struktural sakakatup gerbang

Katup gerbang has the characteristics of small fluid resistance, applicable pressure and temperature range, etc. It is one of the most commonly used cut-off valves, used to cut off or connect the medium in the pipeline. The shrinkage of the diameter can reduce the size of the parts, reduce the force required for opening and closing, and expand the application range of the parts. But after the diameter shrinks. The fluid resistance loss increases. Low-pressure katup gerbangs in China generally use cast iron materials. Cast iron katup gerbangs often have serious problems such as freezing and cracking of the valve body and falling off of the gate. The carbon steel stem of the cast iron katup gerbanggampang dikaratake, kualitas gasket pengepakan kurang, lan kebocoran internal lan eksternal serius.

1. Enkapsulasi karet sakabèhé: Gerbang nganggo karet berkualitas tinggi kanggo karet njero lan njaba umume. Teknologi vulkanisasi karet nggawe gerbang tervulkanisasi kanggo mesthekake dimensi geometris sing akurat, lan karet lan gerbang cor ductile disambungake kanthi kuat, ora gampang tiba lan elastis memori Apik.

2. Kursi gerbang dhasar ngisor: tradisionalkatup gerbang often silt in the groove at the bottom of the valve due to foreign objects such as stones, wood, cement, iron filings, sundries, etc. after the pipe is flushed with water, which can easily cause water leakage due to inability to close tightly. Phenomenon, the bottom of the elastic seat seal katup gerbang adopts the same flat-bottom design as the water pipe machine, which is not easy to cause debris siltation and makes the fluid flow unimpeded.

3. Awak katup casting presisi: Awak katup nggunakake casting presisi, lan dimensi geometris sing tepat nggawe bagian njero awak katup tanpa proses sing apik kanggo mesthekake tutup saka tutup kasebut.
