Stainless steel pneumatic three-way ball valve characteristics and development

stainless steel pneumatic three-way ball valve with its small fluid resistance, simple structure, small volume, light weight, the advantages of wide scope of application and loved by consumers. Stainless steel tee ball pneumatic valve and pneumatic valve flange gate is belong to the same type of pneumatic valves, the difference in its closure is a ball, the ball goes around the center line of the pneumatic valve body for a pneumatic valves to open and close. Pneumatic ball valve in the line is mainly used to do cutting, distribution, and change the flow direction of medium. Today, small make up take you to understand the pneumatic valve industry of stainless steel tee ball some performance characteristics and working principle of pneumatic valve.
stainless steel tee ball working principle of pneumatic valve:
love is to rely on rotating pneumatic valve to pneumatic valve open or occlusion. Pneumatic ball valve switch lightweight, small size, can make a large caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries. A, open process:

A, in the closed position, sphere subjected to mechanical pressure pneumatic valve stem, press on the pneumatic valve seat;
B, when counterclockwise rotation handwheel, pneumatic valve stem is reverse movement, the Angle at the bottom of the flat sphere release pneumatic seat;
C, pneumatic valve stem continue to ascend, and with the pneumatic valve rod guide pin of interaction in the spiral groove, sphere began without some friction spinning;
D, until to the fully open position, pneumatic valve stem ascending to limit position, sphere rotation to the full open position.
2, close the process:
A, closing, rotating the handwheel clockwise, pneumatic stem began to drop and the ball left pneumatic seat begin to spin;
B, continue to rotate handwheel, pneumatic valve stem is embedded in the spiral groove on the role of the guide pin, pneumatic valve stem and sphere ° rotating at the same time;
C, is close to closing, sphere has been in contact with the pneumatic valve seat without rotating under the condition of the °;
D, the hand wheel rotation of the last few laps, pneumatic valve stem mechanically wedge Angle at the bottom of the plane to the oppression of a sphere, make its strong pressure on the pneumatic valve seat, achieve completely sealed
stainless steel pneumatic three-way ball valve structure features:
jacket structure: the valve can be directly mounted on the pipeline pneumatic online inspection and maintenance, can effectively reduce the parking device, reduce the cost. This kind of pneumatic valves shall generally be installed in the pipeline;
open-close friction-free, completely solve the traditional pneumatic valves for sealing surface friction each other and affect the sealing problem;
low torque design. Special structure design of the pneumatic valve stem, only with a small hand could easily open/close the pneumatic valve;
wedge seal structure. Pneumatic valve by pneumatic valve stem provides mechanical force, wedge pressure the ball into the pneumatic seat and seal, pneumatic valve's sealing is not affected by changes in the pipeline pressure difference, under various conditions has a reliable guarantee for sealing;
single pneumatic seat design. Eliminates the pneumatic valve lumen medium because of abnormal pressure and problems affecting the safety of use;
the self-cleaning structure of sealing surface. When the ball tilting away from the pneumatic valve seat, fluid in the pipeline along the sphere uniform sealing surface into ° through, not only eliminates the high velocity of pneumatic seat local scour, also washed away by the accumulated on the surface of the sealing material, achieve the goal of the clean.
stainless steel pneumatic three-way ball valve has the following advantages:
. Fluid resistance is small, the resistance coefficient and with the length of the section is equal;
。 Simple structure, small volume, light weight;
。 Close and reliable, the pneumatic ball valve sealing surface of materials widely used plastic, sealing good, also has been widely used in vacuum system;
。 Easy to operate, open and close quickly, from open to close as long as the rotating °, is advantageous for the remote control;
。 Pneumatic valve has simple structure, convenient maintenance, the ball sealing ring are generally activities, remove the replacement is convenient;
。 In full open or full close, the sphere and the pneumatic valve seat sealing surface and the dielectric isolation, medium through the pneumatic valve sealing surface does not cause erosion;
。 Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
pneumatic three-way ball valve only need to use pneumatic operation USES air rotation operation and small rotational torque can be closed tightly. Full equality of the pneumatic valve body cavity for medium resistance is very small, straight flow channel. Generally think of pneumatic ball valve is suitable for direct to do the most open and close. Pneumatic ball valve itself is the main characteristics of compact structure, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene.
