The structure characteristics of stainless steel tee ball pneumatic valve

stainless steel tee ball the closing of the pneumatic valve is a ball, the ball goes around the center line of the pneumatic valve body for a pneumatic valves to open and close.
the structure characteristics of stainless steel tee ball pneumatic valve:
. Open-close friction-free, completely solve the traditional pneumatic valves for sealing surface friction each other and affect the sealing problem;
　　. 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;
　　. Single pneumatic seat design. Eliminates the pneumatic valve lumen medium because of abnormal pressure and problems affecting the safety of use;
　　. Low torque design. Special structure design of the pneumatic valve stem, only with a small hand could easily open/close the pneumatic valve;
　　. The structure of sealing wedge. 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;
　　. Since the clean structure of the 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.
stainless steel pneumatic three-way ball valve installation and maintenance should be paid attention to the following:
. To leave the position of the pneumatic valve handle rotation;
　　. Cannot be used for throttling;
　　. The pneumatic ball valve with the actuator shall be installed upright.
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 the process:
A. Sphere by the pneumatic valve in the closed position of the rod mechanical pressure, press on the pneumatic valve seat;
　　B. When turn the handwheel counterclockwise, 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 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 the limit position, sphere rotation to the full open position.
2. Closing 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 closed, a sphere has been in contact with the pneumatic valve seat without rotating under the condition of the °;
　　D. 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, completely sealed
