Today we are going to explain to you the structure characteristics and working principle of the stainless steel gate Industrial Valves of stainless steel gate valve used in our normal life what is the specific structure. 1, well-selected materials, in line with the relevant standards at home and abroad, the materials of high quality in an all-round way. 2, conform to the requirements of domestic and international advanced standard, reliable sealing, excellent performance, beautiful appearance. 3, seal pair of advanced and reasonable, the disc and seat sealing surface with different hardness of too stand ( Stellite) Cobalt-based hard alloy surfacing and become, reliable sealing, high hardness, wear resistance, high temperature resistance, good corrosion resistance, abrasion resistance, long service life. 4, the valve stem through surface nitriding treatment and conditioning, with good corrosion resistance, abrasion resistance and abrasion resistance. 5, adopting the wedge gate structure, large diameter setting thrust bearing, friction small, and is equipped with impact handwheel, easy opening and closing. Next is the stainless steel gate get working principle: the gate valve gate, linear motion, with the stem called lifting lever gate ( Also called rising stem gate valves) 。 Usually in lifting lever on the trapezoidal thread, through the valve at the top of the nut and guide groove on the valve body, the rotation movement into linear motion, which is the operating torque thrust into operation. Sealing surface can only rely on medium pressure to seal, that is, to rely on medium pressure to press the sealing face of gate to the other side of the seat to ensure sealing face seal, this is the seal. Most is adopt compulsory seal gate Industrial Valves, the Industrial Valves is closed, to rely on outside force forced the ram pressure to the seat, to ensure the sealing surface sealing.
