Orbit plug valve is also called the bevel gear drive the warlords, suitable for aviation kerosene, crude oil, light oil, natural gas, liquefied gas, gas pipelines, chemical medium pipeline, as an ideal device for truncated medium. Double double off and working principle of key drainage function of the valve is two pieces of sealing slide action is installed in the plug.
The scope of application:
Bevel gear drive full size will warlords for aviation kerosene, crude oil, light oil, natural gas, liquefied gas, gas pipelines, chemical medium pipeline, as an ideal device for truncated medium.
Valves in the switch process, the sealing surface of the Orbit Plug Valve body and the slide sealing surface without any contact, therefore, the sealing surface friction, no wear, long service life of the valve, the switching torque is small;
The valve in the repair, no need to remove the valve from the pipeline, the valve bottom cover open, change a pair of slide sheet can be very convenient repair;
The valve body and a cock as full size, medium without flow resistance in through the valve, and can pass the ball to clean pipe, overcomes the reducing valve disadvantages;
The full size body cavity warlords plated with hard chrome, sealing area of strong smooth;
The slide of the elastic sealing by fluorine rubber, and moulded in slide surface groove. With fire protection function of metal on metal seal backing as elastic seal;
The valve has an automatic discharge device (Bei Xuan), in the valve is completely closed, to prevent the abnormal pressure of the Inverted Pressure Balance Lubricated Plug Valve and check valve effect;
The valve switch indicator and the switch position synchronization, can accurately display the gear drive full size will switch state warlords
State orbit plug valve fully open, the valve plug aligned channel, the minimum pressure drop can guarantee the ideal. Turn the handwheel to plug in valve direction, at the same time to drive the valve plate to rotate 90 degrees, when to turn the hand wheel, the plug will be under pressure, the valve opening to both sides, the valve will be tightly pressed on the seat, the valve closed; when the hand wheel to rotate in the opposite direction, first of all to make the plug upward movement, so that the valve on the seat out, to turn the hand wheel, driven to plug valve rotated 90 degrees, channel alignment in the body end plug channel, so that the valve is fully open state.
