1-PC ball valve has the following advantages
A, a one-piece ball valve has the following advantages:
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.
2. The structure is simple, small in size and light in weight.
3. It is close and reliable. At present, the sealing surface material of the ball valve is widely used in plastic and has good sealing performance. It has also been widely used in vacuum systems.
4. The operation is convenient, the opening and closing is rapid, and the rotation is 90° from full opening to full closing, which is convenient for long-distance control.
5. The maintenance is convenient, the ball valve has a simple structure, and the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium does not cause erosion of the sealing surface of the valve.
7. Wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.
B, one-piece ball valve can be divided into straight-through type, three-piece ball valve and right angle according to its channel position. The latter two ball valves are used to distribute the medium and change the direction of the medium. The following items should be noted for the installation and maintenance of wide-type ball valves:
1. Leave the position where the valve handle rotates.
2. Cannot be used for throttling.
The ball valve with 3 transmission mechanism should be installed upright.
C, the working principle of the wide-type ball valve is to make the valve unblocked or blocked by rotating the valve. The ball valve switch is light in weight, small in size, can be made into a large diameter, reliable in sealing, simple in structure, convenient in maintenance, and the sealing surface and the spherical surface are often closed, and is not easily eroded by the medium, and is widely used in various industries.
D, a one-piece ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. Ball valve is a new type of valve widely used in recent years, which has the following advantages:
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.
2. The structure is simple, small in size and light in weight.
3. It is close and reliable. At present, the sealing surface material of the ball valve is widely used in plastic and has good sealing performance. It has also been widely used in vacuum systems.
4. The operation is convenient, the opening and closing is rapid, and the rotation is 90° from full opening to full closing, which is convenient for long-distance control.
5. The maintenance is convenient, the ball valve has a simple structure, and the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium does not cause erosion of the sealing surface of the valve.
7. Wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, all the spheres should appear at the entrance and exit, thus cutting off the flow.
One-piece ball valve is a relatively new type of ball valve. It has some unique features unique to its structure. For example, the switch has no friction, the seal is not easy to wear, and the opening and closing torque is small. This reduces the size of the actuators that are supplied. With multi-turn electric actuators, the medium can be adjusted and tightly closed. It is widely used in the conditions of strict cutting off of water supply and drainage in petroleum and chemical cities.
