Abstract

The invention relates to pipeline valves, and discloses a magnetic power flexible membrane starting pipeline switching valve. The magnetic power flexible membrane starting pipeline switching valve is provided with a valve body and a gland, wherein a medium inlet channel and a medium outlet channel are formed in the valve body, and a transition cavity is formed in the gland and communicates the inlet channel with the outlet channel. The magnetic power flexible membrane starting pipeline switching valve is characterized in that a flexible membrane is pressed and installed between the gland and the valve body, is located in the transition cavity and can connect or disconnect the outlet end of the inlet channel and the inlet end of the outlet channel; a pressure balancing hole is formed in the flexible membrane and communicates the inlet channel and the transition cavity; a magnetic valve set is installed on one side, close to the outlet channel, of the valve body and the gland, a rotary knob is installed on the gland and is provided with a cantilever, the cantilever is located at the top of a cylinder sleeve of a magnetic power valve set and is provided with a magnetic block, and the magnetic block and a magnetic column inside a slide sleeve in the magnetic power valve set are arranged in an opposite heteropole mode. The magnetic power flexible membrane starting pipeline switching valve solves the problems that an existing switching valve is difficult to seal, inconvenient to operate and short in service life, and leakage is easy to cause; and the magnetic power flexible membrane starting pipeline switching valve is widely used in various water supply pipelines and gas supply pipelines.

Description

The agile diaphragm of magnetomotive starts the pipe switch valve

Technical field

The present invention relates to the pipeline valve series products, the agile diaphragm of especially a kind of magnetomotive starts the pipe switch valve.

Background technique

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 reliably is that ordinary ball valve is difficult to be competent at.

Summary of the invention

Purpose of the present invention 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 the pipe switch valve.

Concrete scheme of the present invention is: the agile diaphragm of magnetomotive starts the pipe switch valve, have valve body and gland, in valve body, offer medium inlet/outlet passage, on gland, be provided with adapter cavity and be communicated with the 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, being connected between the outlet end that can be communicated with or disconnect 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, the 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 the sliding sleeve lower end is provided with outer step seam, and the sliding sleeve outer cover is equipped with Returnning spring, the sliding sleeve internal upper part is equipped with the magnetic post, bottom is equipped with plug and is arranged over against the boss of core print seat, and the magnetic post is connected with plug, on the cylinder sleeve sidewall, has flowing hole and is communicated with adapter cavity; Knob is housed on gland, on knob, is designed with cantilever, 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 present invention, on gland, over against the pressure compensation opening on agile diaphragm, an anti-silting pin is being housed, anti-silting pin passes pressure compensation opening and arranges.

In the present invention, between knob and gland, be designed with two position-limit mechanisms of open and close.

working principle of the present invention 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 the magnetic post directly over, the magnetic post is picked up, driving simultaneously plug lifts, can open the pressure relief vent on core print seat, thereby the pressure medium in the release adapter cavity, agile diaphragm is entering the import of upwards opening outlet passage under the pressure medium effect and with inlet passage, is being communicated with (referring to Fig. 3), it is valve opening, when the needs throttle down, the rotation knob, make magnet ring leave magnetic post top, spacing position is closed in arrival, Returnning spring top sliding sleeve drive plug moves 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 present invention is isolated action fully, 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 present invention and conventional ball valve class valve structurally with on control mode, be all a kind of upgrading regeneration product.
