Abstract

The utility model discloses an electromagnetic valve. The electromagnetic valve comprises a valve body, a valve cover, a water inlet chamber and a water outlet chamber, wherein a water inlet is positioned in front of the water inlet chamber, a spring and an iron core are arranged in the valve core from the top down in sequence, the lower end of the iron core is in contact with a rubber stopper, the rubber stopper is arranged in a sealing chamber in the valve body, a film assembly arranged in the sealing chamber, the film assembly comprises two sealing films and a pressure relief piece, the two sealing films are positioned at two sides of the rubber stopper, the pressure relief piece is positioned at the middle position below the two sealing films, the water inlet chamber and the water outlet chamber are provided with sewage draining pipes, sewage draining outlets of the sewage draining pipes are communicated with a sewage collection purifying pond, and the sewage collection purifying pond is communicated with the water inlet. According to the electromagnetic valve disclosed by the utility model, the water inlet chamber and the water outlet chamber are provided with the sewage draining pipes, thus sundries in a liquid passageway can be filtered, and a pressure relief hole can not be blocked; and the sewage draining outlets of the sewage draining pipes are communicated with the sewage collection purifying pond, and thus purified water can enter into the water inlet again for cyclic utilization.

Description

A kind of solenoid valve

Technical field

The utility model relates to a kind of solenoid valve.

Background technique

Be used for the end solenoid valve with conducting controlled of metallic conduit to the liquid road at present, its structure comprises coil block, valve body, is connected water supply connector and water output connector on the valve body, in water supply connector, is provided with drain pipe; So that filter out foreign material; Be unlikely to stop up relief hole, but this structure can only filter out a part of foreign material, what metallic conduit was inner wears out; The iron filings that produce can only be deposited in the valve body, cause whole solenoid valve malfunctioning.Therefore, need provide a kind of new technological scheme to solve the problems referred to above.

The model utility content

The purpose of the utility model provides that a kind of strainability is good, the solenoid valve of liquid road reusable edible.

The technological scheme that the utility model adopts is:

A kind of solenoid valve comprises valve body, valve gap, intake chamber and water-supplying chamber, is provided with water intake before the said intake chamber; Be provided with water outlet after the said water-supplying chamber, be provided with spring and iron core in the said valve gap from top to bottom successively, said iron core lower end contacts with rubber stopper; Said rubber stopper places in the closed chamber in the valve body; Be provided with membrane module in the said closed chamber, said membrane module comprises two sealing films and pressure release part, and two sealing films are positioned at the both sides of rubber stopper; Said pressure release part is positioned at the neutral position of two sealing film belows; Be equipped with drain pipe in said intake chamber and the water-supplying chamber, the sewage draining exit of said drain pipe all is communicated with the dirty clarifier-tank of collection, and the dirty clarifier-tank of said collection is communicated with water intake again.

Said drain pipe is provided with filter screen.

Have relief hole on the said pressure release part.

The beneficial effect of the utility model: be equipped with drain pipe in intake chamber and the water-supplying chamber; Can filter out the foreign material in the liquid road; Be unlikely to stop up relief hole, the sewage draining exit of drain pipe all is communicated with the dirty clarifier-tank of collection, and the water after the purification can get into the water intake recycle again.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Wherein: 1, valve body, 2, valve gap, 3, intake chamber, 4, water-supplying chamber, 5, water intake, 6, water outlet; 7, spring, 8, iron core, 9, rubber stopper, 10, closed chamber, 11, sealing film, 12, the pressure release part; 13, relief hole, 14, drain pipe, 15, filter screen, 16, sewage draining exit, 17, collect dirty clarifier-tank.

Embodiment

As shown in Figure 1, a kind of solenoid valve of the utility model comprises valve body 1, valve gap 2, intake chamber 3 and water-supplying chamber 4; Be provided with water intake 5 before the intake chamber 3, be provided with water outlet 6 after the water-supplying chamber 4, be provided with spring 7 and iron core 8 in the valve gap 2 from top to bottom successively; Iron core 8 lower ends contact with rubber stopper 9, and rubber stopper 9 places in the closed chamber 10 in the valve body 1, is provided with membrane module in the closed chamber 10; Membrane module comprises two sealing films 11 and pressure release part 12, has the both sides that 13, two sealing films 11 of relief hole are positioned at rubber stopper 9 on the pressure release part 12; Pressure release part 12 is positioned at the neutral position of two sealing film 11 belows, is equipped with drain pipe 14 in intake chamber 3 and the water-supplying chamber 4, and drain pipe 14 is provided with filter screen 15; The sewage draining exit 16 of drain pipe 14 all is communicated with the dirty clarifier-tank 17 of collection, collects dirty clarifier-tank 17 and is communicated with water intake 5 again.

Working principle: during the solenoid valve outage; Iron core 8 drives rubber stopper 9 and is displaced downwardly to the relief hole 13 that clogs in the pressure release part 12 under the effect of the restoring force of spring 7; Promptly close relief hole 13; Make sealing film 11 seal the water-supplying chamber 4 of valve body 1, intake chamber 3 no longer communicates with water-supplying chamber 4, thereby makes the liquid road interrupt; When solenoid valve was switched on, iron core 8 received the attraction of field coil and drives rubber stopper 9 and upwards remove from relief hole 13, no longer seals the water-supplying chamber 4 of valve body 1, promptly opens this relief hole 13, thereby made intake chamber 3 and water-supplying chamber 4 communicate, and made that the liquid road is unimpeded.

Be equipped with drain pipe 14 in intake chamber 3 and the water-supplying chamber 4, can filter out the foreign material in the liquid road, be unlikely to stop up relief hole 13, the sewage draining exit 16 of drain pipe 14 all is communicated with the dirty clarifier-tank 17 of collection, and the water after the purification can get into water intake 5 recycles again.
