Abstract

The utility model relates to an electromagnetic valve, composed of a valve body, a casing, a coil, a stop sheet, a movable iron core, a pressure spring, a pressure block, a guide sleeve, a sealing plug, a block, a film, a sealing pad, a hollow rivet, screws, a pad and an O-shaped ring. The utility model has reasonable and reliable design; the utility model can be used in water and other liquids, and the power utilization safety does not to be worried. As the utility model uses the bistable structure design, the electricity can be saved by about one time, and the disadvantages of electric shock operation and device electricity leakage are prevented; as the ultrathin film is used, the valve reaches to the ultra low voltage state. When the valve is used for a solar energy water heater, a water pipe can be prevented from being frozen in winter, and an actual all-weather product is realized.

Description

Electromagnetic valve

This use is novel to belong to the parts of opening or closing on the pipeline, particularly be the electromagnetic valve of installing on the pipeline.

Now no matter be industrial oil pipe commonly used, tracheae, or life in water pipe commonly used or the like all need valve; Manually-operated gate is arranged, and pneumatic valve also has electric valve; Can be divided into normal open type valve and normal close type valve, for example 96228272.3 in the patent documentation " pipeline gas safety valve " is exactly the electromagnetic valve of single type; The solenoid valve of using on " round-the-clock " solar water heater partly, being normal open type or normal close type electromagnetic valve, all is monistic electromagnetic valve also, must switch on during the closure or openness, not only electricity consumption is many, brings a series of problems such as operation inconvenience and Electrical Safety again.

The purpose of this utility model provides a kind of bistable super-low voltage electromagnetic valve that normal close type can be made the dual-purpose of normal open type, power saving, safety again that promptly can be used as.

The novel purpose of this use is achieved in that accompanying drawings is as follows:

A kind of electromagnetic valve, its structural feature is:

1. valve body 1 upper opening and housing 3 shell of turriform electromagnetic valve that is composed of a fixed connection;

2. in the inner chamber of housing 3, be provided with stifled 15, the hollow rivet 21 of moving iron core 8, ratchet 10, stage clip 11, sealing from top to bottom successively; Hollow rivet 21 be positioned at sealing stifled 15 below, be set with catch 18, diaphragm 19, sealing gasket 20 on the hollow rivet 21; The border, outer of diaphragm 19 is sealed between housing 3 and the valve body 1; Briquetting 13 is between sealing stifled 15 and housing 3; Guide pin bushing 14 tops are between briquetting 13 and housing 3, and its underpart is between valve body 1 and housing 3; In the cavity of stage clip 12 between guide pin bushing 14 upper ends, briquetting 13, housing 3;

3. coil 4 is fixed on housing 3 shaft shoulders by locking plate 5; Be provided with screw 6 in the housing 3 top center holes.

Accompanying drawing 1 is the electromagnetic valve cross-sectional view

Accompanying drawing 2 is electromagnetic valve Application Example schematic representation on solar water heater

Description of drawings and embodiment:

By accompanying drawing 1 as can be known, the two ends of valve body 1 are connection road to be taken over, and valve body 1 is linked together as the turriform shell of solenoid valve by screw 16 and packing ring 17 with housing 3; Electromagnetic coil 4 is purchased part for finished product, is fixed on by locking plate 5 on the top shaft shoulder in housing 3 outsides, and its position should be lower than moving iron core 8, and coil 4 should attract to press down with moving iron core 8 during energising; Moving iron core 8, a support spring 9, ratchet 10, stage clip 11, sealing stifled 15 and hollow rivet 21 are housed in the inner chamber of housing 3 from top to bottom; Be with catch 18, diaphragm 19, sealing gasket 20 on the hollow rivet 21 successively; The cylindrical border of diaphragm 19 is sealed between valve body 1 upper shed plane and housing 3 bottom planes; Be provided with stage clip 12 in the cavity between stifled 15 outer walls of sealing and housing 3 inwalls, stage clip 12 lower ends are pressed in the upper end of guide pin bushing 14, the lower end of guide pin bushing 14 to level to abduction, and between housing 3 and valve body 1; Ratchet 10 is an outsourcing piece, and its characteristic is for when pushing for the first time, and last ratchet 10-1 rotates with following ratchet 10-2 and makes ratchet 10 elongated, when push for the second time ratchet 10-2 rotation at present revert to again about ratchet 10-1 intersect with 10-2 and shorten.

In housing 3 upper end center holes, be provided with screw 6,, divide into O type circle 7 at screw 6 in order to strengthen the sealability of solenoid valve; Between guide pin bushing 14 bottom abduction ends, housing 3, valve body 1, be provided with O type circle 2.

The working condition brief introduction is as follows: start electric switch, coil 4, produce magnetic force, attract moving iron core 8 to press down, promote a support spring 9 and ratchet 10 and move down same 10 transpositions of ratchet at present that move down, make the ratchet total length elongated until last ratchet 10-1 with following ratchet 10-2 engagement, promote sealing stifled 15 and move down, promote hollow rivet 21 again and move down, and be on the valve port in the upper shed of valve body 1 sealing gasket 20 press seals.Fluid cutout in the valve body 1 at this moment; Because ratchet is elongated, outage also can keep cutout; When the needs fluid flow, as long as again by an electric switch, moving magnet 8 presses down a support spring 9 and a ratchet 10, ratchet 10-2 rotates, and ratchet 10 shortens, and rises in the effect lower lock block 13 rising drive sealings stifled 15 of stage clip 12, hollow rivet 21 also rises, and valve port is opened, the fluid flow in the valve body 1.

By accompanying drawing 2 as can be known, this solenoid valve is installed on 23 places, upper end of solar water heater inlet pipe 22; During last water, throttle down 25 and 26 is opened valve 24, clicks the solenoid valve electric switch, makes it be in opening state, and tap water promptly injects water tank 27, treat shower nozzle 28 water outlets after, throttle down 24; Press electromagnetic valve switch once more, make it be in closed condition, open valve 25 immediately, the pipe inner cold water is emitted immediately, and winter, water pipe can prevent bursting by freezing, and this is the distinctive feature of this valve.

Advantage of the present utility model is a lot; At first this electromagnetic valve adopts injection molding type coil, direct lead wire formula Wiring is used also to protect in water and other liquid and has been levied Electrical Safety; Use ratchet and bistable structural design But the disadvantage that operates electric shock, equipment leakage has been exempted in nearly one times of power saving; Use ultra-thin diaphragm, make valve Reach the ultralow pressure state; This valve applications on solar water heater, can be prevented the water pipe from freezing crack in winter, Realize round-the-clock product truly.
