Orbit Plug Valve Wikipedia, the working principle, product characteristics and structural features

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.

This product is close to the gate, and the flange connection, the Orbit Plug Valve body adopts the principle of rotation to achieve open and close. Reasonable design, simple and beautiful, to meet the market demand. Suitable for pressure level 150~900Lb (1.6~32.0MPa), pipeline various working temperature of -29~150 ℃ petroleum, chemical, pharmaceutical, chemical, electric power industry and so on, cut off or connected to the pipeline medium.

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.

Structural characteristics:

Valves in the switch process, the sealing surface of the 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 Connection Lift Plug Valve 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 valve chamber 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.

Working principle.

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
