Online Inquirybrief introduction
One piece ball valve and flange gate valve belong to the same type of valve, the difference is that its closing part is a ball, and the ball rotates around the center line of the valve body to open and close a valve. Ball valve is mainly used to cut off, distribute and change the flow direction of medium in pipeline. Wide ball valve is a new type of valve widely used
Advantage
1. The fluid resistance is small, and its resistance coefficient is equal to that of the same length of pipe section.
2. Simple structure, small volume and light weight.
3. It is tight and reliable. At present, the sealing surface material of ball valve is widely used in plastic, with good sealing performance, and also widely used in vacuum system.
4. It is easy to operate and fast to open and close. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control.
5. The maintenance is convenient, the ball valve structure is simple, the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.
6. When the valve is fully open or closed, the sealing surface of the ball and the valve seat shall be isolated from the medium. When the medium passes through, the corrosion of the valve sealing surface will not be caused.
7. It has a wide range of applications, ranging from small diameter to several millimeters and large diameter to several meters, from high vacuum to high pressure. When the ball rotates 90 degrees, it should be spherical at the inlet and outlet, so as to cut off the flow.
application
One piece ball valve is a relatively new type of ball valve, which has some unique advantages of its own structure, such as no friction switch, seal is not easy to wear, opening and closing torque is small. This reduces the size of the actuator. Equipped with multi rotation electric actuator, the medium can be adjusted and cut off tightly. It is widely used in petrochemical city water supply and drainage and other conditions requiring strict cut-off.
Working principle
The working principle of wide ball valve is to make the valve unblocked or blocked by rotating valve. The ball valve has the advantages of light switch, small volume, large caliber, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are always in closed state and are not easy to be eroded by medium, so it is widely used in various industries
