Working Principle And Precautions Of Stainless Steel Ball Valve

The working principle of Sanitary Ball Valve is to make the valve unblocked or blocked by rotating the valve core. The ball valve body can be integral or combined. Here is some knowledge about stainless steel ball valves.

Brief introduction of ball valve:

Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Ball valve is a new type of valve that is widely used. Its working principle is to make the valve unblocked or blocked by rotating the valve core. The ball valve is light and small in size. It can be made into a large caliber. It has reliable sealing, simple structure, and convenient maintenance. The sealing surface and the spherical surface are often in a closed state and are not easily eroded by the medium. It is widely used in various industries.

Features of ball valve:

Stainless steel ball valves can be closed tightly with only a 90-degree rotation and a very small torque. *The equal inner cavity of the valve body provides a very small resistance and straight flow channel for the medium. The main features of the ball valve are its compact structure, easy operation and maintenance. Stainless steel ball valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.
The ball valve body can be integral or combined. This type of valve should generally be installed horizontally in the pipeline. Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. Stainless steel ball valve materials are divided into 304, 316, 321 stainless steel ball valves.
Precautions for ball valve operation:
1. Stainless steel valves should avoid contact with other metals, be careful not to allow foreign matter such as garbage to enter the interior, and be stored in a well-ventilated environment.
2. In order to protect the gasket inside the ball valve, the ball valve should be in a fully open state, and the gate valve, stop valve, and check valve should be stored in a fully closed state.
3. Before piping construction, confirm the state of the interface, whether there is oil stains, etc., and if so, remove the attached foreign matter.
4. The flow direction is specified on the valve body. During piping construction, the flow direction shown on the valve body should be confirmed. During installation, the fluid direction should be consistent with the arrow on the valve body.

5. When connecting the pipe to the valve, first fix the valve end close to the pipe with a wrench, and then tighten the steel pipe with a pipe clamp. If the thread is over-tightened, the end of the steel pipe will damage the inside of the ball valve.

6. When tightening the bolts, do not tighten only one side, but tighten the bolts on the corresponding diagonal line.

7. For valves using sealing rings, due to the characteristics of the sealing ring, the pressure of the sealing parts will drop during storage, resulting in leakage. Be sure to tighten the loose screws before use. Loose screws should also be checked regularly during normal use.
