Abstract
The utility model relates to a water control type stop valve. A valve body at the inner side of a valve cap is provided with a piston cylinder, a piston is connected with the head part of a valve rod positioned in an outlet pipe diameter, and the tail part of the valve rod is fixed with a valve clack positioned at the outlet side of a valve seat. An offsetting spring used for causing valve clack to always have the trend of closing the valve seat is arranged between the valve cap and the piston, and the valve cap is provided with through holes respectively communicated with a piston cavity and an inlet pipe diameter. The lower end of a control rod is fixed with a control valve clack used for opening and closing the through holes, and a pressure relief passage is arranged between the control valve clack and the outlet pipe diameter. Since the inlet pipe diameter is communicated with an inner cavity of the piston, the offsetting spring is arranged between the valve cap and the piston, water and gas can not be supplied for the inlet pipe diameter, and the valve seat is always closed by the valve clack due to the function of the offsetting spring. Therefore, the utility model has the advantage of reliable and steady operation, and simultaneously, the valve clack fixed on the valve rod at the outlet side of the valve seat is formed with linkage with the valve rod and the piston. Due to favorable axiality, the valve clack can be lifted stably, sealed parts are steady, sealing performance is good, and the water control type stop valve can be opened and closed flexibly.
Description
Technical field
The utility model relates to the valve in a kind of fluid delivery pipeline, especially refers to a kind of stop valve that fluid-transporting tubings such as water, gas are used that is suitable for.
Background technique
At present, stop valve is in transporting water, indispensable equipment in the delivery lines such as gas, be to be used for the opening and closing of controlling plumbing fixtures media flow, and the existing multiple pattern of existing stop valve, is exactly wherein a kind of pattern as the utility model patent of China number for ZL99206135.0 " a kind of stop valve ", the main valve stem of its disclosed stop valve is connected with spool is vertical, the two places in the valve body altogether, and main valve stem is hollow valve rod, the lower end communicates with valve pocket, has the relief hole that communicates with valve chamber on the main valve stem wall, suit auxiliary valve rod in the main valve stem, the two is coaxial, the inwall of auxiliary valve rod outer wall and main valve stem matches, and the upper end of auxiliary valve rod is provided with the keying knob, serves as that axle rotates in main valve stem at auxiliary valve rod with its center, by the revolute valve rod, the pressure release passage upper end is connected with relief hole, because said structure, so this stop valve has been avoided leakage problem, and simple in structure, flexible operation.But its shortcoming is the coaxial of main valve stem and auxiliary valve rod, thereby difficulty of processing is big, the cost height, and when pipeline occur cutting off the water, when stopping the supple of gas or steam, spool is fallen and be in opening state, the result then when in the pipeline again Lai Shui, the resource phenomenon can appear when coming gas wasting, as if be provided with locking mechanism on major and minor valve rod, then operation inconvenience, structure also become complicated.In addition, the sealing surface of spool and valve body is taper, not only requires the machining accuracy height, and after repeatedly using, owing to factors such as friction have influenced the sealing of its conical contact face, thereby has shortened the working life of this stop valve.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, and a kind of reliable operation is provided, the water control type stop valve of good seal performance and long service life.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this water control type stop valve comprises valve body, be positioned at that valve body is enterprising, the valve seat of outlet caliber jointing place, flap and take off the knob that closes the valve gap that is connected and be positioned at the controlling rod upper end with valve body, the valve body that it is characterized in that described valve gap inboard is provided with piston cylinder, described piston links to each other with the valve rod head that is positioned at the outlet caliber, and described valve rod afterbody is fixed with the flap that is positioned at the valve seat outlet side; Between described valve gap and piston, be provided with the multiple resilience spring that makes flap have closed valve seat trend all the time; Described valve gap is provided with the penetration hole that communicates with piston cavity, import caliber respectively; The lower end of described controlling rod is fixed with the control flap that can open and close above-mentioned penetration hole, also is provided with pressure release passage between described control flap and outlet caliber.
Be respectively equipped with the first passage and the third channel of mutual perforation on valve body between described penetration hole and the import caliber and the valve gap.
Described pressure release passage is made up of the four-way that is positioned at the second channel on the valve body and is positioned on the valve gap of mutual perforation.
Be provided with the lobe frame of fixing control flap between described control flap and the controlling rod.
Be provided with the fixedly valve petal shelf of flap between described flap and the valve rod.
Be connected by the valve rod setting sleeve between described valve petal shelf and the valve rod.
The described valve gap outside is fixed with valve bonnet, described controlling rod be threaded with swivel nut between the valve gap at valve bonnet, described swivel nut is fixed on the valve bonnet by positioning seat again.
Also be provided with the Pointing sign board of indication valve opening size on the described valve bonnet.
Compared with prior art, advantage of the present utility model is: because the import caliber communicates with the inner chamber of piston, valve gap and piston space are provided with Returnning spring, even thereby cut off the water, stop the supple of gas or steam in the import caliber, because the effect of Returnning spring, flap is closed valve seat all the time, so reliable operation, steady; Flap is fixed on the valve rod of valve seat outlet side simultaneously, itself and valve rod, piston constitute interlock, because coaxality is good, so the flap lifting is steady, the sealing position is stable, good seal performance, and sealing force can be as required, and the ratio of appropriate design piston and the sectional area of flap is avoided because of the excessive valve that damages of exerting oneself, thereby long service life, open and close flexible, convenient.
