Soft sealed ball valve is a commonly used control valve, which consists of a ball body, valve body, valve stem, soft seal, handwheel, etc. The sphere is fixed by the valve body and valve stem, and a handwheel is installed on the valve stem. The handwheel drives the sphere to rotate through the valve stem, thereby controlling the opening and closing of the valve. The soft seal is composed of the space between the valve body and the valve stem. When the valve stem rotates, the soft seal will change shape, thus playing a sealing role.
The advantages of soft sealed ball valves are: they have good sealing performance and can effectively prevent liquid leakage; Its structure is simple and easy to install and maintain; Its operation is flexible and can achieve remote control; Its traffic loss is small, which can effectively improve the efficiency of the system.
Characteristics of Soft Seal Ball Valve:
1. It has good sealing performance and can effectively prevent liquid leakage;
2. It has good corrosion resistance and can effectively prevent corrosion;
3. It has good operational performance and can effectively improve work efficiency;
4. It has good maintainability and can effectively reduce maintenance costs.
Structure of soft sealed ball valve:
A soft sealed ball valve consists of a ball body, valve body, valve stem, soft seal, handwheel, and other components. The sphere is fixed by the valve body and valve stem, and a handwheel is installed on the valve stem. The handwheel drives the sphere to rotate through the valve stem, thereby controlling the opening and closing of the valve. The soft seal is composed of the space between the valve body and the valve stem. When the valve stem rotates, the soft seal will change shape, thus playing a sealing role.
The principle of soft sealed ball valve:
The working principle of a soft sealed ball valve is that when the valve stem rotates, the ball also rotates, thereby changing the opening and closing state of the valve. When the valve stem rotates, the soft seal will also change shape, thus playing a sealing role.
The standard for soft seal ball valves:
The standards for soft sealed ball valves mainly include GB/T 12237-2005 “Ball Valves for Petroleum and Chemical Industry”, GB/T 12238-2005 “Butterfly Valves for Petroleum and Chemical Industry”, GB/T 12239-2005 “Check Valves for Petroleum and Chemical Industry”, GB/T 12240-2005 “Globe Valves for Petroleum and Chemical Industry”, etc.
Soft sealed ball valves have a wide range of applications and can be used in industries such as petroleum, chemical, thermal, power, metallurgy, mining, environmental protection, and water treatment to control parameters such as flow rate, pressure, and temperature of various media.
In short, soft sealed ball valves are efficient, reliable, and structurally simple control valves. They have a wide range of applications and can meet the needs of various industries. They are a very useful control valve.
