Abstract
The utility model discloses a diaphragm stop valve started and stopped by magnetic force which is characterized in that the armature starts and stops the drainage hole on a diaphragm is a permanent magnet. The magnetic force starting appliance is provided with a permanent magnet with a convertible magnetic field direction. The conversion mode can be operated by hand and by arranging a coil at the outside of the permanent magnet which is powered on momentary electric current to convert the direction of the electric current. Therefore, the utility model does not use electricity or uses less electricity, and the problems of burnout of a heating coil and buzzing noise of electromagnetism can not occur. Furthermore, the valve can be designed into a stop valve being able to adjusting flow rate.
Description
The utility model relates to a kind of diaphragm type stop valve of magnetic force open/close.
A kind of known membrane valve, barrier film is separated into two-part And with valve pocket and links up two valve pockets by the aperture on the barrier film, conduction hole on the barrier film, the one end leads to media outlet, the other end is sealed by armature, when the electromagnet energising ， And attraction armature that places the valve body outside, during away from conduction hole as magnetic starter, conduction hole is opened, medium in the valve pocket flows out from media outlet through conduction hole, and at this moment, the pressure difference that acts on the barrier film disappears, barrier film is lifted off a seat under the pressure medium effect, and the medium import promptly directly communicates with media outlet.The membrane valve of this structure, when valve was in opening state, electromagnet must be switched on, and so just brought following problem: the one, electromagnetic coil is switched on for a long time, and power consumption is big; The 2nd, electromagnetic coil continuous operation, overheated burning out easily; The 3rd, there is the electromagnetism buzzing noise that is difficult to overcome, interference environment.
The purpose of this utility model is the diaphragm type stop valve of the magnetic force open/close of a kind of not power consumption of design or little power consumption.
Solving scheme of the present utility model is: armature adopts permanent magnet, and magnetic starter is the permanent magnet that magnetic direction can be changed.The conversion of magnetic direction can realize by manual and automatically controlled dual mode.
This specification provides the following drawings:
Fig. 1: manual mode magnetic force barrier film stop valve structure schematic representation;
Fig. 2: manual flow adjustable magnetic barrier film stop valve structure schematic representation;
Fig. 3: the structural representation of electric-controlled type magnetic force barrier film stop valve magnetic starter part.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Example one: diaphragm type stop valve shown in Figure 1 is assembled by valve body (1), barrier film (6), armature (7), valve gap (8) and permanent magnet (11).Valve seat (2), valve pocket (3), medium import (4) and media outlet (5) are arranged in the valve body (1); Aperture (9) and conduction hole (10) are arranged on the barrier film (6), and aperture (9) is linked up and is separated into two-part valve pocket (3) by barrier film (6), and conduction hole (10) is then linked up valve pocket (3) and media outlet (5); Permanent magnet (11) is installed on the valve gap (8) by supporting axle (12), constitutes magnetic starter; Armature (7) is permanent magnet; When rotating permanent magnet (11), armature (7) is when being subjected to repulsion, and armature (7) is pressed on the barrier film (6), and conduction hole (10) is closed, and armature (7) is when being subjected to gravitation, and armature (7) leaves barrier film (6), and conduction hole (10) is opened.
Example two: diaphragm type stop valve shown in Figure 2 is on the basis of diaphragm type stop valve shown in Figure 1, in valve pocket (3), set up bowl-type spring (13) and cover seat (14), bowl-type spring (13) is pressed on the barrier film (6), armature (7) is enclosed within the cover seat (14), and bowl-type spring (13) and cover seat (14) are equipped with through hole (15,16).When armature (7) externally left barrier film (6) under the action of a magnetic field and promotes (14) displacement of cover seat, bowl-type spring (13) was out of shape the aperture that ， And can limit barrier film (6) thereupon.If permanent magnet (11) is swung in certain scope, the suffered magnetic force of armature (7) changes, and the aperture of barrier film (6) is also changing, and has so just reached the purpose of Flow-rate adjustment.
Example three: electric-controlled type magnetic force barrier film stop valve.This valve is the magnetic starter difference with the difference of manual mode magnetic force barrier film stop valve, the magnetic starter of this valve as shown in Figure 3, permanent magnet (17) is fixed on the valve gap (8), its material is a same sex permanent magnet, one coil (18) is arranged in its outside, series connection one instantaneous current direction change-over circuit (19) on the energising circuit of coil (18), this circuit can be two groups of parallel circuits of being made up of switch and rectifier.By control, realize the conversion of instantaneous energising and current direction to two switch on and off.
Aforesaid manual mode magnetic force diaphragm shutoff valve, not power consumption, electric-controlled type magnetic force diaphragm shutoff valve also only needs instantaneous energising, the power consumptive province, and do not exist coil heating to burn and electromagnetism buzzing noise problem. The stop valve that can be designed to adjustable-flow of manual mode, if electric-controlled type set up control circuit, also can realize far distance controlled, therefore, this magnetic force diaphragm shutoff valve all has broad application prospects civilian, industrial.
