Soft seal gate valve, industrial valve, the opening and closing part of soft seal gate valve is the gate, the movement direction of the gate is perpendicular to the fluid direction, the 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 model gate valve form a wedge. The wedge angle varies with the valve parameters. The nominal diameter is DN50~DN1200, and the operating temperature: ≤200℃
After the sealing surface of the valve seat and the valve plate is corroded or deformed, the valve plate can automatically compensate for the pressure tight cover and the automatic pressure balance between the valve and the valve plate. Solve the problem that the soft sealing material is rubbed and the sealing surface is damaged. The sealing sleeve of the gate valve can be replaced, which greatly increases the use of the valve.
