Introduction: In the field of marine work and ships in our country, ball valves are inseparable from these work. Ball valves can be used to control the control of the fluid. In the 50s of the 20th century, the emergence of ball valves promoted the development of industry. Take you into the world of ball valves.

In China, in some fields, such as: petroleum industry, chemical manufacturing, pharmaceutical engineering, water conservancy engineering, iron and steel industry, power industry ......Ball valves are widely used and play a vital role in China's national economy.

The function of the ball valve is mainly to cut off the flow, distribute the flow rate and change the flow direction, it can rotate ninety degrees. The ball valve has many functions and can also be used as a switch.

Next, I will introduce the characteristics of the ball valve: first, it has good wear resistance, and the reason why it has wear resistance is that the valve core is welded with alloy steel when it is sealed, and its sealing ring is also welded with alloy steel. Second, it has good sealing performance, and the reliability of the sealing of the ball valve is extremely high, because its sealing is manual running-in, when the valve core and the sealing ring are completely fitted.

Third, the switch of the ball valve is lightweight, and the bottom of its sealing ring has a spring between the valve core and the sealing ring. Fourth, the ball valve has a long service life, and it is mostly used in the petroleum industry, chemical manufacturing industry, power plants, paper mills and other places.

There are many types of ball valves, and a common ball valve in Jieqian Zhongshao is pneumatic ball valve. Pneumatic ball valve has many advantages: 1. It can be anti-static, because there are springs in many places in the ball valve, which can allow the static electricity generated in it to be exported during use.

2. Long service life, because it uses a lubricant with better performance, which greatly reduces the loss of the ball due to friction. 3. The resistance of the airflow gate valve is the smallest among all the gate valves. 4. The tightness of the ball valve seat is excellent.

Classification of Ball Valves::

According to the function classification of ball valves: 1. Bypass valve, which is generally used to switch for static water. 2. Air valve, which is to remove the air when filling the container with water; When the water in the container is emptied, the pontoon inside slowly descends.

3. The pressure relief valve can remove the pressure when it is opened or closed, so as to avoid wear. Fourth, the sewage valve can discharge the sewage from the lower part of the ball.

Precautions: First, before disassembling the dismantling ball valve, check whether the upper and lower pipes of the ball valve have been relieved. Second, some non-metallic parts in the ball valve should not be soaked in the detergent for too long when cleaning.

Third, when installing, the screws should be tightened gradually and evenly, and the ability to be too large should not be too large. Fourth, some non-metallic parts should be cleaned with pure water or alcohol. Fifth, the parts of the disassembled individual ball valve can be soaked, and some stains can be wiped off with a silk cloth to clean all the stains as much as possible.

A ball valve is a common fluid control valve that uses a rotating ball to control the opening and closing of the fluid. Ball valves have the following main functions:

1.Opening and closing the fluid channel: The main function of the ball valve is to control the flow of fluid, and by rotating the sphere, the channel can be completely opened or closed, so as to control the passage or blocking of the fluid.

2.Quick shut-off fluid: The ball valve has the ability to quickly cut off the fluid, when the ball rotates to the closed position, the valve will quickly block the flow of the fluid, thus effectively cutting off the passage of the medium.

3.Flow regulation: Ball valves usually have a hole in the ball, and the size of the opening of the hole can be adjusted by rotating the ball, so as to control the flow of fluid. Ball valves have a smaller flow adjustment range than other valve types and are typically used in applications that require higher flow rates.

4.Reliability & Tightness: The ball valve is simple in design, reliable in operation, and has good sealing performance. Ball valves usually use sealing rings, sealing surfaces and other structures to ensure the tightness of the valve, which can effectively prevent fluid leakage.

5.Corrosion resistance: Ball valves are often used in occasions with high requirements for media, such as chemical, oil, natural gas and other industries. Ball valves are typically made of corrosion-resistant materials and are able to operate stably in corrosive media for long periods of time.

It should be noted that the ball valve can not only be closed and closed to achieve two-way on-off control, but also can realize multi-channel control through special structures, such as three-way and four-way ball valves. In addition, the ball valve can also be equipped with electric, pneumatic and hydraulic actuators as needed to achieve remote control and automatic operation. <>

<> ball valve is an evolution of the plug valve. It has the same rotational 90-degree lifting action, except that the body is a sphere with a circular through hole or channel through its axis. The ratio of the spherical surface to the channel mouth should be such that when the ball is rotated 90 degrees, the sphere should be fully presented at the inlet and exit, thus cutting off the flow.

The ball valve only needs to be rotated 90 degrees and the torque is very small to close tightly. The fully equal cavity of the valve body provides a straight-through flow path with minimal resistance to the medium. Ball valves are generally considered to be most suitable for direct opening and closing, but recent developments have designed ball valves to allow them to throttle and control flow.

The main feature of the ball valve is that it is compact, easy to operate and maintain, and is 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. The ball valve body can be monolithic or combined.

The working principle of the ball valve is that the closure (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control.

In China, ball valves are widely used in petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries, and occupy a pivotal position in the national economy. It has a motion of 90 degrees of rotation, and the body is a sphere, with circular through-holes or channels through its axis.

The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium, it only needs to rotate 90 degrees of operation and a small torque to close tightly. Ball valves are most suitable for switching, shut-off valves, V-type ball valves. In addition to the parameters of the pipeline, special attention should be paid to the environmental conditions of its use, because the electric device in the electric valve is an electromechanical equipment, and its use state is greatly affected by its use environment.

Under normal conditions, special attention should be paid to the use of electric ball valves and butterfly valves in the following environments.
