Abstract
The utility model relates to a bidirectional diaphragm type electromagnetic valve, which is mainly composed of a valve body, a valve nozzle, a plunger, a spring, coils, a skeleton, a ring magnet, a flanged disk, a pure iron gasket, a pure iron stopping seat, a cyathiform diaphragm, a metal inner lining, a valve cover, a valve cap, a plug cock, screws and screw bolts. The cyathiform diaphragm is supported by the metal inner lining, thereby, all the structural members, particularly the moving components (the plunger and the spring) in the valve cover are isolated from fluid media. The contamination of impurities in fluid is avoided so that the bidirectional diaphragm type electromagnetic valve has enhanced self working reliability and extended service life.
Description
The utility model belongs to a kind of solenoid valve, particularly relates to a kind of fluid break-make bidirectional electromagnetic valve of control automatically that is used for.
Existing known solenoid valve is unidirectional to be many, promptly automatically shut down by electrical pulse, and armrest is moving open-minded.Idol has bidirectional electromagnetic valve, also can't avoid contacting with flowing medium because of the particularly reciprocating component of inner structural members, stain by its objectionable impurities, resistance to motion increases gradually, and can't guarantee under constant electrical pulse the reliability of solenoid valve break-make and long lifetime.
The purpose of this utility model is that a kind of improved diaphragm-type electromagnetic valve will be provided, in its structure, adopted a cup-shaped barrier film, it is contacting of the particularly reciprocating component of buffer fluid and solenoid valve inner structural members effectively, thereby guaranteed the reliability and the long lifetime of solenoid valve break-make.
The purpose of this utility model is achieved in that the normally used circular flat flashboard of a solenoid valve changes into a cup-shaped barrier film, flat shape plane, the old-fashioned garden flashboard that plays a part of its thick garden shape, its uncovered annular webbing then compresses in the circular groove that is sealed in valve body by flange plate, the cylindrical sidewall of cup-shaped barrier film supports thin and high resilience by metal inner lining, so, cup-shaped diaphragm seals contacting of solenoid valve all structural members except that valve body, valve nozzle and flowing medium, avoided in the fluid impurity to the particularly contamination of motion component of electromagnetic valve structure spare.When plunger in the enclosed cavity of cup-shaped barrier film and valve bonnet during to-and-fro motion, the circular flat bottom of cup-shaped barrier film is affected by plunger, leaves or seal valve nozzle, the sidewall of cup-shaped barrier film is folding thereupon or stretch, thereby has formed opening or turn-offing of solenoid valve.
Owing to adopted such scheme, the inner structural members that makes solenoid valve particularly motion component is not subjected to the contamination of objectionable impurities in the fluid, thereby has guaranteed reliability and long lifetime that solenoid valve is worked under constant electrical pulse.It is cup-shaped barrier film that the core of architecture advances only is normally used circular flat flashboard is changed, so be easy to realize.
Concrete structure of the present utility model is provided by following examples and accompanying drawing:
Accompanying drawing is the sectional drawing of the two-way diaphragm-type electromagnetic valve structure that the utility model proposes.
In the accompanying drawing, 1 flange plate; 2 valve bodies; 3 cup-shaped barrier films; 3-1 shape webbing; The 3-2 circular flat bottom; 4 metal inner linings; 5 bonnets; 6 cocks; 7 valve nozzles; 8 screws; 9 plungers; 10 ring magnets; 11 coils; 12 skeletons; 13 guide rods; 14 pure iron end seat; 15 valve bonnets; 16 springs; 17 pure iron packing rings; 18 bolts.
In the accompanying drawing, the uncovered annular webbing (3-1) of cup-shaped barrier film (3) is compressed in the circular groove that is sealed in valve body (2) by flange plate (1).Its circular flat bottom (3-2) plays flashboard, has sealed the valve nozzle of being located in the valve body (2) (7), and (A) chamber in the valve body (2) is cut off with (B) chamber, and solenoid valve is in off state.Cup-shaped barrier film (3) is set in the outside of metal inner lining (4), and is screwed tight up and down by bonnet (5) and cock (6) and to be sealed into one.Plunger (9) becomes loosening by screw (8) and bonnet (5) and is connected, when plunger (9) is subjected to the action of a magnetic field upstream or downstream, just drive cup-shaped barrier film (3) and be synchronized with the movement, make the up valve nozzle (7) that leaves of its circular flat bottom (3-2)---(A), (B) chamber communicates, valve is open-minded; Or the descending sealing valve nozzle (7) that compresses---(A), (B) chamber is cut off, valve turn-offs.In this process, folding or extending movement are made in the high resilience owing to approach of the sidewall of cup-shaped barrier film (3) synchronously.Coil (11) is wound in the enameled cable rule in the upper cavity of skeleton (12), and the annular magnetic iron rule is set in the bottom of skeleton (12), and its integral body is packed in the valve bonnet (15).Pure iron ends seat (14) riveted fixing and goes up in the top intracardiac in valve bonnet (15).Guide rod (13) upper end screws tight the central position of ending seat (14) at pure iron, in the cavity of lower end fixing spring (16) and the plunger of packing into (9).Pure iron packing ring (17) places between ring magnet (10) and the flange plate (1), with three bolts valve bonnet (15), flange plate (1) and valve body (2) is fixed together at last.
Claims (3)
1, the two-way diaphragm-type electromagnetic valve of a kind of fluid is characterized in that replacing the normally used circular flat flashboard of solenoid valve with a cup-shaped barrier film (3), is sleeved on the outside of metal inner lining (4), and screws tight by bonnet (5) and cock (6) and to be sealed into one.Plunger (9) then becomes loosening by screw (8) and bonnet (5) and is connected.The annular webbing (3-1) of cup-shaped barrier film (3) is compressed in the circular groove that is sealed in valve body (2) by flange plate (1), and its circular flat bottom (3-2) plays flashboard, directly contacts with valve nozzle (7), cuts off (A), (B) chamber of valve body (2).The cylindrical sidewall of cup-shaped barrier film (3) approaches and high resilience.
2,, it is characterized in that cup-shaped barrier film (3) has an annular webbing (3-1) and the circular groove of valve body (2) directly to seal according to the said two-way diaphragm-type electromagnetic valve of claim 1.
3, according to the said two-way diaphragm-type electromagnetic valve of claim 1, it is characterized in that the circular flat bottom (3-2) of cup-shaped barrier film (3) plays flashboard, directly contact with valve nozzle (7), can cut off (A), (B) chamber of valve body (2).
