Stainless Steel Knife Gate Valve By Tianjin Tanghai Valve Manufacturing Co., Ltd
Product Overview
Key Features
Knife Gate valve (TH-PZV)
The opening and closing part of the knife gate valve is the knife /gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The manual knife gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces, The two sealing surfaces of the most commonly used mode gate valve form a wedge, and the wedge angle varies with valve parameters, usually 50. The gate of the wedge knife gate valve can be made into a whole, called a rigid gate; it can also be made A gate that can produce a small amount of deformation to improve its process characteristics and make up for the deviation of the angle of the sealing surface during the processing.This kind of gate is called an elastic gate.
When the knife gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, rely on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. The gate valve adopts forced sealing, that is, when the valve is closed, the gate must be forced to press against the valve seat by external force to ensure the sealing performance of the sealing surface
Area of application
Knife gate valve is suitable for viscous particles, often used in beverage, paper-making, pulp industry, industrial sewage, urban sewage treatment, chemical plants, bulk material transportation, fly ash treatment industries;
