stainless steel gate is one of the most widely used gate valve, due to its characteristics of small resistance, simple appearance, deeply society from all walks of life love, so how does it work? Let's have a look. Stainless steel gate valve working principle: gate valve disc and stem in a straight line movement, known as lifting lever gate ( Was also known as gate valves) 。 Usually on the lifting rod has a trapezoidal thread, through the valve at the top of the nut and the guide groove on the valve body, converting rotary motion to linear motion, the operating torque thrust into operation. Sealing surface can only rely on medium pressure seal, that depend on medium pressure, the gate will be to the other side of the valve seat sealing surface pressure, to ensure the sealing surface of the seal, the sealing automatically. Most of the gate was forced to seal, that is, when the valve is closed, must rely on outside force to press the valve to the seat, to ensure that the seal on the surface of the seal. Stainless steel gate valve features: 1. Material selection elegant, in line with the relevant standards at home and abroad, the material total quality is higher. 2. In line with the domestic and foreign advanced standards, reliable sealing, good performance, beautiful appearance. 3. Seal of advanced and reasonable, the disc and seat sealing surface with different hardness of cobalt-based hard alloy, reliable sealing, high hardness, wear resistance, high temperature resistance, good corrosion resistance, scratch resistance, long service life. 4. Stem after surface nitriding treatment has a good corrosion resistance, scratch resistance and abrasion resistance. 5. USES elastic wedge gate structure, thrust bearing used in medium and large diameter, friction, impact is equipped with manual, easy to open and close.
