What is the concept and specifications of stainless steel spheres?
Concept of stainless steel sphere
The ball of a ball valve is floating, and under the pressure of the medium, the stainless steel ball can produce a certain displacement and press tightly against the sealing surface at the outlet end, ensuring the sealing of the outlet end. The floating ball valve has a simple structure and good sealing performance, but the ball bears all the load of the working medium and is transmitted to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. When subjected to high pressure impact, the ball may deviate.
This structure is generally used for medium and low pressure ball valves. The main characteristics of ball valves are compact structure, reliable sealing, simple structure, easy maintenance, and the sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium. They are easy to operate and maintain and are suitable for general working media such as water, solvents, acids, and natural gas, as well as for media with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. They are widely used in various industries. The valve body of a ball valve can be integral or modular.
The specifications of stainless steel spheres include: two-way ball (straight ball), three-way ball, four-way ball, L-shaped ball (curved ball), ball with handle, fixed ball, hollow ball, curved ball, floating ball, three-way ball, straight ball steel plate ball, etc. And can design and develop various non-standard and required spheres according to customer requirements.
The blank of the sphere is made by welding, casting, and forging steel plates. The materials include cast steel, forged steel, 201, 304, 304L, 316, 316L and other materials.
