Stainless Steel Ball Valve Suppliers share with you.
1. Frictionless opening and closing: completely solves the problem of traditional valves due to the sealing surfaces rubbing against each other and affecting the seal;
2. Top-mounted structure: the valve installed on the pipeline can be directly inspected and maintained online, which can effectively reduce device parking and cost reduction, this valve should usually be installed horizontally in the pipeline;
3. Single seat design: eliminates the problem of abnormal pressure rise in the valve cavity due to the media and affect the safety of use;
4. Low torque design: special structure design of the valve stem can be easily opened and closed with only a small handle;
5. Wedge seal structure: the valve relies on the mechanical force provided by the stem to press the ball wedge on the valve seat for sealing, so the sealing performance of the valve is not affected by changes in line pressure, and the sealing performance is reliably guaranteed under various working conditions;
6. Self-cleaning structure of the sealing surface: When the ball is tilted away from the seat, the fluid in the pipeline will pass through the sealing surface of the ball evenly in 360°, which not only eliminates the local flushing of the seat by the high-speed fluid, but also flushes away the buildup on the sealing surface to achieve the purpose of self-cleaning.
Stainless Steel Three-Way Ball Valve
1、Low fluid resistance. Its resistance coefficient is equal to the resistance coefficient of the same length of pipe section ;
2, simple structure, small volume, light weight, tight and reliable, at present, the sealing surface material of the ball valve has been widely used in plastic, with good sealing performance, has also been widely used in the vacuum system;
3, easy to operate, open and close quickly, from fully open to fully closed only need to rotate 90 °, convenient remote control; easy maintenance, ball valve structure is simple, the seal ring is generally movable, easy to disassemble;
4, when fully open or fully closed, the ball and seat sealing surface is isolated from the medium. When the medium passes, the medium will not cause corrosion of the valve sealing surface;
5, it has a wide range of applications, the diameter range from a few millimeters to several meters, from high vacuum to high pressure can be applied.
Installation and maintenance precautions.
To leave the position of the valve handle rotation; can not be used for throttling; ball valve with transmission mechanism should be installed vertically.
Stainless Steel Three-Way Ball Valve is dependent on the rotation of the valve to make the valve open or closed, the ball valve switch is light weight, small volume, can be made into a large caliber. Reliable sealing, simple structure, easy maintenance, sealing surface and spherical surface is often airtight, not easy to be eroded by the medium, in various industries have been widely used.
I. Opening process.
In the closing position, the ball is pressed against the seat by the mechanical pressure of the stem, when the handwheel rotates counterclockwise, the stem moves in the opposite direction, the angular plane at the bottom separates the ball from the seat, the stem continues to be elevated and interacts with the guide pin inside the spiral groove of the stem, so that the ball begins to rotate without friction until it reaches the fully open position, the stem is elevated to the limit position and the ball rotates to the fully open position.
II. Closing process.
When closing, rotate the handwheel clockwise, the stem starts to fall, so that the ball leaves the seat and starts to rotate, continue to rotate the handwheel, the stem is subject to the action of the guide pin embedded in the spiral groove on it, so that the stem and the ball rotate 90° at the same time, about to close, the ball has rotated 90° without contact with the seat, the last few turns of the handwheel rotation, the angular plane at the bottom of the stem mechanically wedge to press the ball, so that it is closely pressed on the seat to achieve a complete seal.
