What are the working principles of stainless steel eccentric semi-ball valves?
stainless steel eccentric semi-ball valve relies on rotating valve chain to make the valve unblocked or blocked. Ball Valve switch is light, small in volume, can be made into large caliber, reliable in sealing, simple in structure, convenient in maintenance, sealing surface and spherical surface are often closed, and are not easy to be eroded by medium, it is widely used in various industries. Eccentric semi-ball valve is mainly used to cut off distribution and change the flow direction of medium in pipelines. Ball Valve is a new type of valve widely used in recent years. It has the following advantages:
The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length. Simple structure, small volume and light weight. Tight and reliable, the sealing surface material of ball valve is widely used in plastic and has good sealing performance, and has also been widely used in vacuum systems. Easy to operate, quick to open and close, from full open to full off as long as the rotation of 90 °, easy to remote control. Maintenance is convenient, Ball Valve structure is simple, sealing ring is generally movable, disassembly and replacement are more convenient. When fully open or closed, the sealing surface of the ball and valve seat is isolated from the medium, and when the medium passes through, it will not cause erosion of the sealing surface of the valve.
stainless steel hemisphere has a wide range of applications, ranging from small to several millimeters and large to several meters, from high vacuum to high pressure. When the ball rotates 90 degrees, it should all appear spherical at the inlet and outlet, thus cutting off the flow. Eccentric semi-ball valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as no friction on the switch, no wear on the seal and small opening and closing torque. This reduces the specifications of the actuator. Equipped with a multi-rotation electric actuator, the medium can be adjusted and tightly cut off. Stainless steel hemisphere is widely used in petroleum, chemical industry, urban water supply and drainage and other conditions requiring strict cutting.
