Abstract
The utility model provides a plunger valve whose sealing is formed by a sealing ring is deformed under the action of external force, and thus a tight matching layer is formed between the sealing ring and the plunger with reliable sealing performance. The plunger valve is provided with a pressure balancing mechanism whose starting and stopping are very flexible. When the valve is completely started or throttled, the sealing face is free from the scouring of medium; the sealing surface obtains protection; the utility model can be stopped and can carry out the flow regulation; the advantage of the utility model is particularly favorable under the condition of high voltage Thus, the plunger valve is widely suitable for the starting, the stopping and the flow regulation of the pipelines, of industry such as petroleum, chemical engineering, etc., which are used for conveying the medium.
Description
The utility model is a kind of plunger valve, is applicable to oil, on the pipeline of chemical industry and other industry fed sheet of a media.
Have stop valve and throttle valve now when opening, medium bump sealing surface, particularly under the situation of high pressure, sealing surface is very easily washed away damage by medium, and working life is short, the switch difficulty.
Task of the present utility model is, makes a kind ofly can overcome above-mentioned shortcoming, and good seal performance, long service life, a kind of flexibly plunger valve of switch is specially adapted to work under the high pressure operating mode.
The technical solution of above-mentioned task is that described plunger valve is made up of the counter balance pocket of handle, transmission nut, valve rod, valve body, plunger and plunger upper end.The seal ring and the gland that compresses seal ring that deformable also are housed outside plunger and have certain intensity, gland forces in seal ring, makes sealing ring deformation also and between the plunger form sealing layer.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a kind of longitudinal sectional drawing of plunger valve.
With reference to Fig. 1, sealing mechanism of the present utility model is made up of gland 3, plunger 2, seal ring 1, and seal ring 1 is out of shape under the pressure of gland 3, makes to form the layer that closely cooperates between seal ring 1 and the plunger 2, thereby stops flowing of medium, forms sealing.
When if seal ring 1 wearing and tearing appearance is poorly sealed, but tightening nut 5, nut 5 compresses valve gap 9, and valve gap 9 forces in gland 3 and is transmitted to seal ring 1, and seal ring 1 further distortion closely cooperates again with plunger 2.Therefore, this plunger valve, sealability is reliable, and the life-span is long, and debugging is convenient.
The utility model balanced controls are, the medium that comes from pipeline is through the plunger 2 inner counter balance pocket A that arrive, make plunger about in the of 2 pressure at two ends be in state of equilibrium substantially.Therefore, opening/shutting valve is very flexible.
Throttle mechanism of the present utility model is, medium flows into from the bottom intermediate hole C of plunger 2, flow out through plunger 2 bottom throttle orifice B, the big I that throttle orifice B flows out medium drives plunger 2 up-down adjustment by valve rod 6, i.e. the size of the arrival of the throttle orifice B on the plunger 2 valve pocket realizes.
When regulating flow, remain between seal ring 1 and the plunger 2 and closely cooperate, medium can not pass through from sealing surface, so sealing surface can be protected, and has prolonged working life.
Of the present utility modelly by sealing be, the throttle orifice B of plunger 2 bottoms arrives the lower end of seal ring 1, and medium can not arrive valve pocket D, and valve is in closed condition.If during full open all-pass flow, the throttle orifice B of plunger 2 bottoms all arrives valve pocket D, and medium arrives valve pocket D by the piston intermediate hole C throttle orifice B that flows through, and flows out delivery outlet.
The working procedure of plunger valve described in the utility model is, when throttle down, handle 8,7 rotations of drive transmission nut turn clockwise, force valve rod 6 to move down, plunger 2 moves down synchronously, when the throttle orifice B of plunger 2 bottoms arrived the lower end of seal ring 1 through seal ring 1, valve was in closed condition.During Open valve, counterclockwise rotation active handle 8 moves up plunger 2, valve opening when moving on to valve pocket D on the throttle orifice B of plunger 2 bottoms, and can regulate flow this moment, and when the throttle orifice B of plunger 2 bottoms all was in valve pocket D, valve was all opened.
Characteristics of the present utility model are, sealing is good, long service life, and switch is flexible. Not only can end but also capable of regulating flow quantity.
