Classification Of Stainless Steel Ball Valve

Dec. 24, 2019

Stainless steel ball valves are a branch of stainless steel valves because they are made of stainless steel. Duplex Stainless Steel Ball Valve Manufacturer has many years of experience in selling stainless steel valves to understand the market situation of stainless steel ball valves. Share it with everyone!

Let's first explain why stainless steel ball valves are so popular in the market, mainly because it is a cost-effective. Because there are many ball valves in the manufacturing industry, the consideration is nothing more than applicability and practicability. Satisfaction of the two means high cost performance. So stainless steel ball valves are such products.

Stainless steel ball valve has many functions, wide application range and strong adaptability. Because stainless steel is corrosion-resistant and wear-resistant, it is very popular. And because the classification of stainless steel ball valves is more detailed, it is not difficult for many manufacturers to choose the stainless steel ball valve that suits them, so the efficiency is a big step forward.

Next, let's talk about the classification of stainless steel ball valves for everyone:

Stainless steel ball valve is divided into floating ball valve, fixed ball valve and elastic ball valve according to the structure. There are certain differences between these three stainless steel ball valves. For details, please refer to the corresponding concepts for analysis.

The ball of the floating ball valve is floating. Under the action of the medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface at the outlet end to ensure the outlet end is sealed. The structure of the floating ball valve is simple and the sealing is good, but the load of the ball bearing the working medium is transmitted to the outlet seal ring, so it is necessary to consider whether the material of the ring ring can withstand the working load of the ball medium. This structure is widely used in medium and low pressure ball valves.

Ball Valve is fixed and does not move when pressed. Fixed ball valves are equipped with floating valve seats. After the pressure of the medium, the valve seat moves, so that the sealing ring is tightly pressed on the ball to ensure the seal. Bearings are usually mounted on the upper and lower shafts of the ball, and the operating torque is small, which is 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, an oil-sealed ball valve has appeared. It not only injects special lubricating oil between the sealing surfaces to form a layer of oil film, which enhances the tightness and reduces the operating torque, which is more applicable. High pressure large diameter ball valve.

The ball of the ball valve is elastic. Both the ball and the valve seat seal ring are made of metal materials. The specific pressure of the seal is very large. The pressure of the medium itself has not reached the requirements of the seal, and external force must be applied. This valve is suitable for high temperature and high pressure media. The elastic sphere is provided with 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 ball and press the valve seat to achieve a seal. Before turning the ball, loosen the wedge-shaped head, and the ball will then return to its original shape, so that there is a small gap between the ball and the valve seat, which can reduce the friction on the sealing surface and the operating torque.

Stainless steel ball valve can be divided into straight type, three type and right angle type according to its channel position. Among them, the famous three-way stainless steel ball valve is divided into T type and L type. The stainless steel three-way ball valve adopts an integrated structure in the structure, less flange connection, high reliability, long service life, large flow capacity, small resistance ball valve is divided into single-acting and double-acting types according to the function, and the characteristics of the single-acting type When the power source fails, the ball valve will be in the state required by the control system.

The above is an explanation of the classification of stainless steel ball valves as a Handwheel Forged Steel Gate Valve Manufacturer, I hope to help everyone.
