Soft-sealed gate valve is a common type of valve, characterized by the use of soft sealing materials (such as rubber, polytetrafluoroethylene, etc.) for the valve seat or valve plate, which can achieve better sealing effect, especially suitable for the control of media such as water and gas. Soft-sealed gate valves are widely used in water supply and drainage, fire protection, HVAC, chemical industry and other industries.
Main features of soft-sealed gate valve
1. Good sealing performance:
- Soft sealing materials (such as rubber) have good elasticity and can fit the valve seat tightly to ensure that the valve does not leak when closed.
- Suitable for low or medium pressure occasions, the sealing effect is better than that of metal-sealed gate valves.
2. Low flow resistance:
- When the valve is fully open, the flow channel is unobstructed and the fluid resistance is small, which is suitable for large flow occasions.
3. Strong corrosion resistance:
- Soft sealing materials usually have good corrosion resistance and are suitable for media such as water, sewage, weak acids and weak alkalis.
4. Easy to operate:
- As the sealing material is soft, the friction force is small when the valve is opened and closed, and the operating torque is small, which is suitable for manual or electric operation.
5. Long service life:
- The soft sealing material has good wear resistance and can effectively extend the service life of the valve.
6. Wide application range:
- Suitable for medium such as clean water, sewage, air at normal temperature and low pressure, widely used in municipal, construction, industry and other fields.
Structure of soft sealing gate valve
1. Valve body: Usually made of cast iron, cast steel, stainless steel and other materials, with high strength and corrosion resistance.
2. Valve wedge: The surface of the valve wedge is covered with soft sealing material (such as rubber), which fits tightly with the valve seat to achieve sealing.
3. Valve stem: Used to connect the valve plate and the operating mechanism to transmit the opening and closing force.
4. Sealing materials: Commonly used soft sealing materials include:
- Rubber: Such as EPDM (ethylene propylene diene monomer rubber), NBR (nitrile rubber), suitable for water and general media.
- Polytetrafluoroethylene (PTFE): Suitable for corrosive media or high temperature occasions.
Application scenarios of soft sealing gate valves
1.Water supply and drainage system: Used in tap water, sewage treatment and other occasions.
2. Fire protection system: Used for the control of fire protection pipes.
3. HVAC system: Used for the control of hot water, cold water, steam and other media.
4. Chemical industry: Used for the control of corrosive media such as weak acids and weak alkalis.
5. Construction industry: Used in building water supply and drainage systems.
