As an industrial power in China, the traditional industry of valves has been constantly evolving and the type of valve is complicated. Stainless steel three-way ball valve with its small fluid resistance, simple structure, small size, light weight, wide range of applications and other advantages by consumers. Today, Xiao Bian will take you to understand the valve industry in the stainless steel tee ball valve some of the performance characteristics and working principle.
Stainless steel three-way ball valve structure Features:
Top-loading structure: installed in the pipeline on the valve can be directly online inspection and maintenance, can effectively reduce the device parking and reduce costs. This type of valve in the pipeline should be generally horizontal installation;
Open and close frictionless: completely solve the traditional valve seal surface friction between the impact of sealing problems;
Low torque design. Special structure design of the stem, just with a small handle valve can easily open and close;
Wedge seal structure. Valve is provided by the valve stem mechanical force, the ball wedge pressed to the valve seat and sealed, so that the valve seal from the impact of pressure changes in the pipeline under various conditions, the sealing performance has a reliable guarantee;
Single seat design. Eliminating the valve cavity medium due to abnormal pressure and affect the use of safety issues;
Sealing surface of the self-cleaning structure. When the ball is away from the valve seat, the fluid in the pipeline passes through the sealing surface of the ball evenly, which not only eliminates the local erosion of the valve seat by the high-speed fluid, but also rushes away the accumulations on the sealing surface to achieve the purpose of self-cleaning .
Stainless steel ball valve has the following advantages:
1. Fluid resistance is small, the resistance coefficient of the same length of the pipe section;
2. Simple structure, small size, light weight;
3. Tight and reliable, the current ball valve sealing surface material widely used plastic, good sealing, vacuum system has also been widely used;
4. Easy to operate, quick opening and closing, as long as the full turn to the full turn 90 °, easy to remote control;
5. Easy maintenance, ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient;
6. In the fully open or fully closed, the ball and valve seat sealing surface and media isolation, the media will not cause erosion of the valve sealing surface;
7. Wide range of applications, the path from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.
working principle:
In the process of opening
1 In the closed position, the ball is pressurized by the valve stem and pressed against the seat.
2 When turning the handwheel counterclockwise, the stem moves backwards and the bottom angled plane disengages the ball from the seat.
3 The stem continues to lift and interact with the guide pin in the helical groove of the stem to allow the ball to start spinning without friction. 4 until it reaches the fully open position, the stem lifted to the limit position, the ball rotates to the fully open position.
When closed
1 When closed, turn the handwheel clockwise and the stem starts to descend and the ball leaves the seat to start rotating.
2 Continue to rotate the handwheel. The stem is guided by the guide pin embedded in the spiral groove on it, causing the stem and sphere to rotate 90 ° at a time.
3 When it is about to close, the ball has rotated 90 ° without contact with the seat.
4 In the last few turns of the handwheel, the angular plane at the bottom of the stem mechanically wedges the ball to press it tightly against the valve seat to achieve a complete seal.
