Stainless steel tee ball pneumatic valve working principle and characteristics of the analysis

as China's industrial powerhouse, pneumatic valve the traditional industry has been growing and pneumatic valve type. Stainless steel pneumatic three-way ball valve with its fluid resistance small, simple structure, small volume, light weight, wide applicable scope, etc, loved by consumers. 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 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.
how it works:

in the process of opening in the closed position, sphere subjected to mechanical pressure pneumatic valve stem, press on the pneumatic valve seat.
when counterclockwise rotation handwheel, pneumatic valve stem is reverse movement, the Angle at the bottom of the plane made a sphere release pneumatic valve seat.
pneumatic valve stem continue to ascend, and pneumatic valve rod guide pin of interaction in the spiral groove, the sphere began to rotate without some friction. Until to the fully open position, pneumatic valve stem ascending to the limit position, sphere rotation to the full open position.
when
in the process of closing off, by rotating the handwheel clockwise, pneumatic stem began to drop and the ball left pneumatic seat begin to spin.
to rotate handwheel, pneumatic valve stem is embedded in the spiral groove on the role of the guide pin, pneumatic stem and ball ° rotating at the same time.
almost closed, sphere has been in contact with the pneumatic valve seat without rotating under the condition of the °.
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, completely sealed.
