Wellhead throttle valve is the new generation of throttle and cut-off valve improved and developed by our company on the basis of gaining the national patent in 1992 and for the needs of oil and gas industry. The valve is a kind of multistage pressure reduction and high-pressure difference regulating valve and can be applied to control the high temperature, high pressure and high pressure difference as well as the flow and pressure of fluid containing solid particles. It adopts nozzle, labyrinth throttle to form the front and back multistage throttle; the valve spool and valve seat adopt hard and soft seal pairs to separate the sealing face and the throttling face, which has improved the throttling ability and sealing reliability of the valve and has the merits of reliable sealing, low noise, little vibration, throttle and cut-off pressure reduction, portable and flexible on and off, etc. The valve is especially suitable for the throttle and cut-off under high pressure. On the condition of high pressure, it possesses the function of pressure reduction and had a long service life. This series of product gains the national patent again after the secondary development .

The wellhead throttle valve is made up of nozzle, plunger-shaped spool, throttle value, valve body and valve rod, etc. It adopts valve seat nozzle, clathrate valve bush throttle structure and has the function of multistage throttle. The throttle pressure difference is big. The nozzle equipment is at the bottom of the valve seat; the valve spool has a balancing hole; the valve spool bush has an orifice. The valve spool and valve seat adopt hard and soft seal pairs to separate the sealing face and the throttling face and form the front and back three-state throttle, which has improved the throttling ability and sealing reliability
