Middle control valve in water supply, steam line is mostly ball valve at present, ball valve is motive sealing contact class valve, its requirement on machining accuracy is high, and manipulation great efforts, working life is short, easily produce wearing and tearing, cause pipeline internal medium to leak, particularly for high pressure air, water lines, needing permanent sealing is reliably that ordinary ball valve is difficult to be competent at.
Summary of the invention
The purpose of this utility model will solve exactly in existing pipeline and adopt ball valve to control, and handles great efforts, and working life is short, and dielectric leakage easily occurs, and brings the problems such as potential safety hazard, provides the agile diaphragm of a kind of leak free magnetomotive to start pipe switch valve.
Concrete scheme of the present utility model is: the agile diaphragm of magnetomotive starts pipe switch valve, there is valve body and gland, in valve body, offer medium inlet/outlet passage, on gland, be provided with adapter cavity and be communicated with inlet/outlet passage, it is characterized in that: between gland and valve body, be pressed with agile diaphragm, agile diaphragm is arranged in adapter cavity, can be communicated with or disconnect being connected between the outlet end of inlet passage and the entrance point of outlet passage; And on agile diaphragm, have pressure compensation opening and be communicated with inlet passage and adapter cavity; At valve body and gland, lean on outlet passage one side, the moving valve group of magnetic is installed, and the moving valve group of this magnetic has cylinder sleeve, and the core print seat with central boss is equipped with in the bottom of cylinder sleeve, core print seat center has pressure relief vent and is communicated with the outlet passage on valve body, sliding sleeve is housed in cylinder sleeve, and sliding sleeve lower end is provided with outer step seam, and sliding sleeve outer cover is equipped with Returnning spring, sliding sleeve internal upper part is equipped with magnetic post, bottom is equipped with plug and is arranged over against the boss of core print seat, and magnetic post is connected with plug, has flowing hole and be communicated with adapter cavity on cylinder sleeve sidewall; Knob is housed on gland, is designed with cantilever on knob, cantilever is positioned at the top of magnetomotive valve group cylinder sleeve and magnetic patch is housed, the magnetic post heteropole positioned opposite in this magnetic patch and sliding sleeve.
In the utility model, on gland, over against the pressure compensation opening on agile diaphragm, an anti-silting pin is housed, anti-silting pin is arranged through pressure compensation opening.
In the utility model, between knob and gland, be designed with two position-limit mechanisms of open and close.
Working principle of the present utility model is: initial closed state is referring to Fig. 2, open valve, turning knob, arrive and open spacing position, make magnetic patch on knob be positioned at magnetic post directly over, magnetic post is picked up, drive plug to lift simultaneously, can open the pressure relief vent on core print seat, thereby the pressure medium in release adapter cavity, agile diaphragm is upwards opened the import of outlet passage and is communicated with (referring to Fig. 3) with inlet passage entering under pressure medium effect, it is valve opening, when needs throttle down, rotation knob, make magnet ring leave magnetic post top, spacing position is closed in arrival, Returnning spring top sliding sleeve drives plug to move down, close the pressure relief vent on core print seat, pressure medium in adapter cavity raises rapidly, thereby compress agile diaphragm throttle down (referring to Fig. 2).
Opening/closing mechanism in the utility model is isolated action completely, thoroughly stopped to leak outside, and without friction, sealability is high, operation is flexibly light and handy, convenient processing and manufacture, and required precision is not high, valve long service life, the utility model and conventional ball valve class valve structurally with in control mode, be all a kind of upgrading regeneration product.
