Abstract
The utility model discloses a hydraulic power assisted stop valve. The hydraulic power assisted stop valve comprises a valve body (1), a valve cover (5) is arranged at the top of the valve body (1), a valve base (4) is arranged in the valve body (1), the valve base (4) and the valve body (1) are of an integral structure, the valve base (4) is provided with a valve clack (2) which is in thread connection with a valve rod (3), the top end of the valve rod (3) is connected with the lower end portion of a piston rod of a power assisted oil cylinder (6), a hand wheel (7) is arranged on the upper end portion of the piston rod, and the power assisted oil cylinder (6) is provided with an oil way connected with an external electric oil pump; both an oil outlet of the power assisted oil cylinder (6) and an oil inlet of the oil pump are connected with an oil tank, and the contact surface of the valve base (4) and the valve clack (2) is provided with a babbitt metal coating. The hydraulic power assisted stop valve has the advantages that the valve rod rapidly ascends and descends through a hydraulic power assisted device, labor is saved during operation, and work efficiency is high; the seal surface is coated by abrasion-resistant alloy, and therefore service life is long.
Description
Technical field
The utility model relates to valve, relates in particular to a kind of hydraulic booster stop valve.
Background technique
,, due to by rotating handwheel band ovable valve stem lifting campaign, there is the excessive problem of friction pair resistance in traditional hand stop valve, brings difficulty for the unlatching of valve, especially in occasions such as high pressure, large scales, even single can't Open valve.In addition, in the process of throttle down, because resistance is larger, often valve rod is declined by less than position, easily causes leakage; In the opening-closing process of valve, rotary type valve and valve seat rub, and also can damage the sealing surface of valve, have reduced the normal service life of valve.
Summary of the invention
For the shortcoming of existing stop valve, the utility model provides a kind of novel hydraulic booster stop valve.
To achieve these goals, the measure taked of the utility model:
A kind of hydraulic booster stop valve, comprise valve body, the valve body top is provided with valve gap, valve inner is provided with and is integrally-built valve seat with it, valve seat is provided with the flap that is spirally connected with valve rod, valve stem tip is connected with the piston-rod lower end section of power-assisted oil cylinder, and the piston rod upper end portion is provided with handwheel, and the power-assisted oil cylinder is provided with the oil circuit that is connected with outside electric oil pump.
The oil outlet of power-assisted oil cylinder is connected filler opening and all with fuel tank, is connected with oil pump.
The surface of contact place of valve seat and flap is provided with the Babbitt coating.
The beneficial effects of the utility model: utilize hydraulic servo to realize the fast lifting of valve rod, rapid operation, high working efficiency, sealing surface applies abrasion resistance alloy, long service life.
