Knife gate valve
- Product Introduction: A gapless gate valve (also known as knife gate valve) with a valve core made of wear-resistant rubber.
- Capacity: 1.6MPa/cm2
- Applications: Huston knife-type gate valve is a large-opening and large-closing type. It is mainly used for abrasive and corrosive slurry media under working conditions that require full opening and full closing, such as cyclone feeding, double-circuit pipelines, etc.
- Product Improvements: The knife gate valve uses special liquid rubber technology to develop wear-resistant rubber as the valve lining. Its elasticity exceeds 80%, ensuring a tight fit between the gap-free gate valve and the gate plate without leakage.
Advantages and Features
- Huston Knife Gate Valve has a long service life, and its lining adopts wear-resistant rubber developed with unique nano-formula technology, with a wear-resistant index of more than 128%, which can extend the service life 2-4 times compared to other rubbers
- It has strong sealing performance, and the wear-resistant rubber elasticity of the lining is greater than 80%, ensuring that the seal does not leak and is not prone to water hammer impact
- the flow port is not easy to block, because the wear-resistant rubber valve lining has a smooth and neat surface, and the blocking situation is almost zero
- the structure is simple, easy to operate and easy to maintain
- No pressure loss.
Working Principle
Huston knife gate valve is mainly composed of valve seat, valve lining, gate plate, bracket and driving device. Under the action of assembly pre-tightening force, the two valve seats make the valve linings fit tightly to form a short butt pipe. The valve is closed and the gate is wedged between the covers of the two valve seats to cut off the fluid. In addition, Huston knife gate valves are manual knife gate valves. They can be made into electric knife gate valves and pneumatic knife gate valves according to user needs. They can be operated on site or remotely controlled. The structural length and flange size of electric gapless gate valves and pneumatic gapless gate valves are generally manufactured in accordance with national standards, and can also be made according to user needs.
