As follows: pneumatic ball valve is a ball valve with a pneumatic actuator, the execution speed of the pneumatic actuator is relatively fast, and the fast switching speed is seconds, so it is usually called pneumatic quick shut-off ball valve. Pneumatic ball valves are usually equipped with a variety of accessories, such as solenoid valves, air source treatment triplets, limit switches, controllers, control boxes, etc., to achieve local control and remote centralized control, and the valve can be controlled in the control room, without running to the scene to manually control, which saves human resources and time and safety to a large extent.

The aspects that need to be paid attention to in the selection of pneumatic ball valves are:

1. The working principle of pneumatic ball valve is to rotate the valve core to make the valve unblocked or occluded. The ball valve switch is lightweight, small in size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, the sealing surface and the spherical surface are often in a closed state, not easy to be eroded by the medium, and have been widely used in various industries.

2. Pneumatic ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium.

3. Pneumatic ball valve is a relatively new type of ball valve, which has some advantages unique to its own structure, such as frictionless switch, sealing is not easy to wear, and the opening and closing torque is small. This reduces the size of the actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and strict cutting of the medium.

Pneumatic ball valve model representation method:

Additional code for ball valves: V means the valve core has a V-shaped structure, D means low temperature, B means heat preservation, P means eccentric structure, U and S and DY mostly represent top-mounted type;

Ball valve name code: Q means ball valve;

Ball valve drive code: 6 means pneumatic;

Connection code: 1 means internal thread, 4 means flange type, 6 means welding, 7 means clamp type.

Foreign manufacturers of ball valves are as follows:

Nico Nico of the United States, Nook Nook of Germany, Norton of the United States, Bon of the United States, Michelle Michelle of the United States, Hitachi Hitachi Valve of Japan.

First, the structure of the imported ball valve

Ball valves are mainly composed of valve body, valve, valve stem, sealing ring and other parts. Among them, the valve body is the main part of the ball valve, which is usually manufactured by casting or forging process virtual key, and its internal cavity is spherical, and there are two channels on the ball, which are the inlet and the outlet.

The valve is the key part of the ball valve, usually using a ball structure, the ball has a circular channel, and the flow of the medium is controlled by rotating the valve. The stem is the part that connects the valve to the handle, and the valve is controlled by rotating the stem. The sealing ring is a key part of the ball valve, which is used to ensure the sealing performance of the valve.

Second, the characteristics of imported ball valves

1.Simple structure and easy operation: The ball valve has a simple structure, easy to operate, can be quickly opened and closed, and is suitable for various industrial fields.

2.Good sealing performance: The ball valve adopts a ball structure, which has good sealing performance, which can effectively prevent the leakage of the medium.

3.Good corrosion resistance: Ball valves are usually made of stainless steel, copper, aluminum and other materials, which have good corrosion resistance.

4.Wide range of application: Ball valves are suitable for various media, including water, gas, oil, steam, etc.

5.High temperature and high pressure resistance: The ball valve can withstand high temperature and high pressure media, and is suitable for various high temperature and high pressure industrial fields.

3. The principle of imported ball valve

The principle of the inlet ball valve is to control the flow of the medium by rotating the valve. When the valve is rotated to the open state, the medium can flow through the channel of the valve; When the valve is rotated to a closed state, the medium cannot flow through the channeling of the valve. The valve usually has a rotation angle of 90 degrees, which allows for fast opening and closing.

The sealing performance of the imported ball valve mainly depends on the sealing ring to achieve. When the valve is rotated to the closed state, the sealing ring can fit tightly to the sealing surface of the valve and the valve body, so as to achieve the sealing performance of the valve.
