Stainless steel three way ball valve and flange gate valve belong to the same type of valve, different in its closing parts is a sphere, the ball revolves around the center line of the valve to achieve a valve opening and closing. Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow.
One Stainless steelTeeGlobe valve Has the following advantages:
1., the fluid resistance is small, and the resistance coefficient is equal to the pipe length of the same length.
2. simple structure, small size, light weight.
3., close and reliable, the ball valve sealing surface materials widely used in plastic, good sealing, vacuum system has been widely used.
4. operation sideThen, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.
5. convenient maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
6. in the full open or full closed, the ball and seat sealing surface and media isolation, the media through, will not cause the valve sealing surface erosion.
7., a wide range of applications, diameter from a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
Gaoping billiards valve can be divided into straight, three and right angles according to its channel position. The latter two ball valves are used to distribute the medium and change the flow direction of the medium. Three pieces of ball valve installation and maintenance should pay attention to the following matters:
1. keep the rotating position of the valve handle.
2. can not be used as throttling.
The ball valve of 3 belt drive mechanism should be installed upright.
Two,The working principle of stainless steel three way ball valve is to make the valve unblocked or blocked by rotary valve. Ball valve switch light, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and sphere often closed state, not easy to be medium erosion, widely used in various industries.
Three,Stainless steel three way ball valve is mainly used in the pipeline to do cutting, distribution and change the flow direction of the medium. Ball valve is widely used in recent years, a new type of valve, it has the following advantages:
1., the fluid resistance is small, and the resistance coefficient is equal to the pipe length of the same length.
2. simple structure, small size, light weight.
3., close and reliable, the ball valve sealing surface materials widely used in plastic, good sealing, vacuum system has been widely used.
4. easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.
5. convenient maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
6. in the full open or full closed, the ball and seat sealing surface and media isolation, the media through, will not cause the valve sealing surface erosion.
7., a wide range of applications, diameter from a few millimeters, large to several meters, from high vacuum, high pressure can be applied. When the ball rotates 90 degrees, the spherical surface should be presented at the inlet and outlet so as to cut off the flow.
Stainless steel three way ball valve is a relatively new type of ball valve, it has its own unique advantages, such as the switch without friction, sealing is not easy to wear, small open and close torque. This reduces the size of the actuator to be executed. With multi rotary electric actuator, medium adjustment and close cutting can be realized. Widely used in [wiki] petroleum [/wiki], [wiki] chemical [/wiki], urban water supply and drainage and other strictly cut off working conditions.
Four, it works as follows
A、 openprocess
1 in the closed position, the ball is pressed by the [wiki] mechanical [/wiki] of the valve stem, tightly pressed on the valve seat.
2 when the handwheel is rotated counterclockwise, the valve stem moves backward and the angular plane at the bottom causes the ball to disengage from the valve seat.
3 the stem continues to ascend, and interacts with the guide pin in the stem spiral groove, so that the ball begins to rotate without friction.
4 until the full open position, the valve stem reaches the limit position, and the ball rotates to the full open position.
B, closing process
1 turn clockwise, turn the handwheel, the stem begins to drop and the ball begins to rotate away from the seat.
2 continue to rotate the handwheel, the stem is embedded in the spiral groove in the guide pin role, so that the stem and sphere at the same time rotate 90 degrees.
When the 3 is closed, the ball has rotated 90 degrees without contact with the valve seat.
4 in the last few turns of the handwheel, the angle plane at the bottom of the valve shaft mechanically wedged against the ball and pressed it tightly against the valve seat to achieve full seal.
Five,Structural features of stainless steel three way ball valve:
1, opening and closing without friction. This function completely solves the traditional [wiki] valve [/wiki] because of the friction between the sealing surface and affect the sealing problem.
2, jacket type structure. The valve installed on the pipeline can be directly checked and maintained on the line, which can effectively reduce the device parking and reduce the cost. This type of valve should be installed horizontally in the pipeline.
3, single seat design. The problem that the medium in the valve is affected by abnormal pressure rise is eliminated.
4 、 low torque design. Special structural design of the valve stem, only with a small hand, the valve can easily open and close.
5, wedge seal structure. The valve is provided by the mechanical force of the valve stem, the ball wedge to the seat and seal, so that the sealing of the valve is not affected by changes in the pressure difference in the pipeline, under various conditions, sealing performance is reliableensure
6. Self cleaning structure of sealing surface. When the ball leans out of the valve seat, the fluid in the pipeline passes evenly through the sphere cover to 360 degrees, which not only eliminates the local erosion of the high speed fluid on the valve seat, but also washes away the accumulation on the sealing surface, so as to achieve the purpose of self-cleaning.
