I believe everyone is familiar with stainless steel ball valves.Stainless steel bulk ultrasonic watermeter body welding versioncan be seen in every corner of the city. They are loved and sought after by people in the industry because of their easy installation and long life. There are many kinds ofStainless steel bulk ultrasonic watermeter body welding versionon the market, how should we distinguish them? Now let Hengke stainless steel ball valve manufacturers take you to understand the classification of stainless steel ball valves!

What are the classifications of Stainless steel bulk ultrasonic watermeter body welding version?

1.Stainless steel bulk ultrasonic watermeter body welding version can be divided into structures

Floating ball valve: The ball of the ball valve is floating. The sphere will produce a certain displacement under the action of the medium pressure, and it will be pressed tightly on the sealing surface of the outlet end to ensure the sealing of the outlet end. The floating ball valve has a simple structure and good sealing performance, but the load of the sphere carrying the working medium is all transmitted to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can bear the working load of the sphere. Spherical medium. This structure is widely used in medium and low pressure ball valves.

Fixed ball valve: The ball of the ball valve is fixed and does not move after being pressed. The fixed ball valve is equipped with a floating seat. After the medium is pressurized, the valve seat moves to make the sealing ring tightly press on the sphere to ensure sealing. Bearings are usually installed on the upper and lower shafts of the ball, with low operating torque, and are suitable for high pressure and large diameter valves. In order to reduce the operating torque of the ball valve and increase the reliability of the seal, the oil-sealed ball valve has appeared. It not only injects a special lubricant between the sealing surfaces, but also forms an oil film, enhances the sealing performance, reduces the operating torque, and is more suitable for high pressure. Large diameter ball valve.

Elastic ball valve: The ball of the ball valve is elastic. Both the ball and the valve seat sealing ring are made of metal materials, and the sealing specific pressure is very large. The pressure of the medium itself cannot meet the sealing requirements, and external force must be applied. The valve is suitable for high temperature and high pressure media. The elastic sphere is an elastic groove at the lower end of the inner wall of the sphere to obtain elasticity. When the passage is closed, the wedge-shaped head of the valve stem is used to expand the sphere and compress the valve seat to seal. Loosen the wedge-shaped head before rotating the ball, the ball will return to its original shape, leaving a small gap between the ball and the valve seat, which can reduce the friction of the sealing surface and the operating torque.

2. The ball valve can be divided into

Straight type, three-way type and right angle type. Three-way ball valve has T type and L type. The T type can connect three orthogonal pipes to each other and cut off the third channel, which can be split and combined. The L-shape can only connect two orthogonal pipes, and cannot keep the third pipe connected to each other at the same time. It only plays a role of distribution. The three-way ball valve adopts an integrated structure in structure, with a four-sided valve seat sealed, less flange connections, high reliability, and lightweight design. The three-way ball core is divided into T type and L type, with long service life, large flow capacity and low resistance.

3. Ball valves are divided by function

There are two kinds of single-acting and double-acting. The feature of the single-acting type is that once the power source fails, the ball valve will be in the state required by the control system.

4. Ball valves can be divided into

One-piece, two-piece, and three-piece.

5. Ball valves can be divided into materials

Stainless steel ball valves (201, 301, 304, 304L, 316L), cast steel ball valves WCB, carbon steel ball valves, ductile iron ball valves, etc.

Well, that’s all about the classification of stainless steel ball valves. I hope that after reading it, I can correctly distinguish and choose the stainless steel ball valve products that suit me. If you still don’t understand, you can also call our company!
