Abstract
The utility model provides a balanced multifunctional valve; the utility model is a combination valve with the functions of cutoff, regulation and back stop. The utility model is characterized in that a balancing chamber is arranged on the upper end of a plunger piston, a valve is flexible to operate, and an intermediate hole and a throttling hole are arranged on the lower end of the plunger piston; when the valve is fully opened and carries out throttling operation, a medium does not erode a sealing ring, a sealing surface can be protected, sealing performance is favorable, and the regulation of flow rate is accurate. A back stop column installed in the middle position of a plunger piston hole enables the valve to have the functions of cutoff, regulation and back stop, the effect that the valve can be triple-purpose is realized, and engineering cost is saved. The utility model is widely suitable for applying to medium conveying pipelines of a petroleum industry, a chemical engineering industry and other industries to use for opening, closing, back stop and the regulation of flow rate.
Description
The utility model is a kind of balanced type multifunction valve, is applicable on the pipeline of oil field, chemical industry and other industry fed sheet of a media.
Now domestic also the existence by, adjusting, three kinds of functions of non-return gathered the multi-functional valve in one, and every deck valve door generally only has simple function, causes that the kind of process pipelines valve and quantity are many, expense is high.And valve sealing face is washed away by medium often, and the life-span is short.
Task of the present utility model is, makes a kind ofly can overcome above-mentioned shortcoming, reach good seal performance, switch flexibly, long service life, it is accurate to regulate flow, non-return is multifunction valve rapidly.
The technical solution of above-mentioned task is: described balanced type multifunction valve is made up of handle, valve rod, valve body, plunger, the plunger upper end is provided with counter balance pocket, the plunger bottom is provided with intermediate hole and throttle orifice, and the non-return post is housed in intermediate hole, and the upper end of non-return post is provided with spring.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a kind of longitudinal sectional drawing of balanced type multifunction valve.
With reference to Fig. 1, the utility model balanced controls are, medium arrives counter balance pocket A by the equalizing orifice on the valve body 3, and plunger is two ends pressure medium self balance about in the of 4, and operated valve is very flexible.
The utility model sealing is that seal ring 6 compresses distortion by gland 5, make it with plunger 4 between form and cooperate layer closely, thereby stop the mobile formation of medium to seal.During throttle down, the throttle orifice B of plunger 4 bottoms is in the lower end of seal ring 6, and seal ring tightly encases the upper end of throttle orifice B, and medium can not reach valve pocket D, and valve is in closed condition.During as full open all-pass flow, the throttle orifice B of plunger 4 bottoms all arrives valve pocket D, and seal ring tightly encases the lower end of throttle orifice B, and medium is arrived valve pocket D and flowed out delivery outlet by the middle C of the plunger throttle orifice B that flows through.
Throttle mechanism of the present utility model is, medium flows into from the intermediate hole C of plunger 4 bottoms, flows into valve pocket D through throttle orifice B, and the big or small rotatable handles 1 that throttle orifice B flows out medium is regulated, and promptly the throttle orifice B size that is in valve pocket D realizes.When regulating flow, seal ring 6 still closely cooperates with throttle orifice B lower end on the plunger 4, the medium sealing surface of not flowing through, so sealing surface is protected, and prolonged working life.
The utility model non-return mechanism is, when valve is under the opening state, quits work as equipment, and when medium flow backwards, non-return post 7 was under the effect of spring 8 and reflux medium, and contacting with the inclined-plane of plunger intermediate hole forms sealing, cuts off flowing of medium.
Working principle of the present utility model is to rotate counterclockwise handle 1 valve rod 2 drive plungers 4 and move up valve opening, and can regulate flow.Clockwise rotate handle 1, valve rod 2 forces plunger 4 to move down, throttle down, and can carry out Flow-rate adjustment.
Characteristics of the present utility model are: switch is flexible, favorable sealing property, life-span Long, adjust flux is accurate, and non-return is rapid, and a valve can replace three valves to use, and falls Low cost reduces flow resistance coefficient, improves water filling and puts rate.
