What is a soft seal ball valve? Working principle of soft seal ball valve

Soft seal ball valve is a commonly used control valve, which consists of a ball, valve body, valve stem, soft seal, handwheel, etc. The ball is fixed by the valve body and the valve stem. A handwheel is installed on the valve stem. The handwheel drives the ball to rotate through the valve stem, thereby controlling the opening and closing of the valve. The soft seal consists of the space between the valve body and the valve stem. When the valve stem rotates, the soft seal changes shape and thus acts as a seal. The advantages of the soft seal ball valve are: it has 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 be controlled remotely; its flow loss is small, which can effectively improve the efficiency of the system. efficiency.

Features of soft sealing 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 operating performance and can effectively improve work efficiency;

4. It has good maintainability and can effectively reduce maintenance costs.

The structure of soft sealing ball valve:

Soft seal ball valve consists of ball, valve body, valve stem, soft seal, handwheel, etc. The ball is fixed by the valve body and the valve stem. A handwheel is installed on the valve stem. The handwheel drives the ball to rotate through the valve stem, thereby controlling the opening and closing of the valve. The soft seal consists of the space between the valve body and the valve stem. When the valve stem rotates, the soft seal changes shape and thus acts as a seal.

Principle of soft seal ball valve:

The working principle of the soft seal ball valve is: when the valve stem rotates, the ball will also rotate accordingly, thus changing the opening and closing state of the valve. When the valve stem rotates, the soft seal will also change its shape, thus playing a sealing role.

Standards for soft sealing ball valves:

The main standards for soft-sealing ball valves are: GB/T 12237-2005 "Ball valves for petroleum and chemical industries", GB/T 12238-2005 "Butterfly valves for petroleum and chemical industries", GB/T 12239-2005 "Check valves for petroleum and chemical industries" 》, GB/T 12240-2005 "Stop valves for petroleum and chemical industry", etc.

Soft-sealed ball valves have a wide range of applications. They can be used in petroleum, chemical, thermal, electric power, metallurgy, mining, environmental protection, water treatment and other industries to control the flow, pressure, temperature and other parameters of various media.

In short, the soft sealing ball valve is an efficient, reliable, simple structure control valve. It has a wide range of applications and can meet the needs of various industries. It is a very useful control valve.
