Fig. 2 is plan view of the present utility model;
Fig. 3 is left view of the present utility model.
Embodiment:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
See shown in Fig. 1-3, with the Electromagnetic water pump of self-priming valve and Decompression valves, comprising: Electromagnetic water pump body 1, Electromagnetic water pump body 1 is provided with intake pipe 11 and an outlet pipe 12, on outlet pipe 12, is provided with self-priming valve 2 and Decompression valves 3.
Specifically, form a valve pocket in Electromagnetic water pump body 1, Electromagnetic water pump also comprises: movable plunger assembly 4, iron core 5, yoke ring 6, enameled cable 7 and coil case 8; Movable plunger assembly 4 is installed in the valve pocket of Electromagnetic water pump body 1, and iron core 5 is connected with movable plunger assembly 4, and yoke ring 6 is set around outside Electromagnetic water pump body 1, and enameled cable 7 is located at outside yoke ring 6; Coil case 8 covers at outside enameled cable 7.
The water outlet of outlet pipe 12 is also provided with safety check 4, and outlet pipe 12 and outside equipment connection, for the water supply to external equipment, the water in valve pocket flows to external equipment after safety check 4.
Described self-priming valve 2 comprises: body 21, be installed on piston 22, first Returnning spring 23 in body 21 and the first lid 24, the first groove 101 is formed between described body 21 and outlet pipe 12, the first described lid 24 offers the first air drain 241, and piston 22 is airtight to the first air drain 241 under the first Returnning spring 23 pressure.
Described Decompression valves 3 comprises: main body 31, be installed on glue head 32, second Returnning spring 33 in main body 31 and the second lid 34, the second groove 102 is formed between described main body 31 and outlet pipe 12, second lid offers the second air drain 341, glue head 32 is airtight to the second groove 102 under the effect of the second Returnning spring 33.
The first lid 24 in self-priming valve 2 is installed on the opening end of body 21, offers the first air drain 241, first air drain 241 and be communicated with the inside and outside air of body 21 on the first lid 24; First Returnning spring 23 is installed between piston 22 and the first lid 24, when original state, does not also inject water in outlet pipe 12, and piston 22 carries out airtight to the first groove 101 under the elastic force effect of the first Returnning spring 23.When the utility model is started working, in outlet pipe 12 after water filling, piston 22 overcomes the elastic force of the first Returnning spring 23 by airtight for the first air drain 241 under the effect of inside water pressure, due to the tapered design in one end that piston 22 is connected with the first air drain 241, the cone point of piston 22, by blocking first air drain 241, prevents the water in outlet pipe 12 from being sprayed by self-priming valve 2.In addition, a recess equal with the first groove 101 cross-section area is offered, so that the circulation of gas in piston 22 and the first groove 101 connecting part.
The utility model sets up a self-priming valve 2 on Electromagnetic water pump, and its effect is: when Electromagnetic water pump just starts, and owing to not having water in valve pocket, and there is air, causes the air pressure inside and outside valve pocket suitable, so, be now difficult to water pump to go out.Being difficult to draw water when just starting to draw water as suction pump, only having and just can draw water smoothly after being full of water in water pump.And the utility model to carry out pouring water operation as suction pump, so the utility model have employed a self-priming valve 2, this self-priming valve 2 is got involved when the utility model is just started working, by the first air drain 241, the gas in outlet pipe 12 is discharged, the air pressure in valve pocket and outlet pipe 12 is made to remain on negative pressure state, thus be beneficial to the filling of water, so that water can be full of in valve pocket and outlet pipe 12 by Electromagnetic water pump fast, make Electromagnetic water pump work fast.Meanwhile, when the utility model is started working, in outlet pipe 12 after water filling, piston 22 overcomes the elastic force of the first Returnning spring 23 by airtight for the first air drain 241 under the effect of inside water pressure, so just guarantees that the water in outlet pipe 12 can not flow out from self-priming valve 2.
In Decompression valves 3, the second lid 34 is installed on the opening end of main body 31, offers the second air drain 341 on the first lid; Second Returnning spring 33 is installed between glue head 32 and the second lid 34, glue head 32 due to the elastic force effect of the second Returnning spring 33 airtight to the second groove 102, second its inwall of groove 102 protrudes formation one protuberance 311 to main body 31 inside, glue head 32 is close to this protuberance 311, makes to form a gap 312 between the diapire of glue head 32 and main body 31.
The utility model sets up a Decompression valves 3 on Electromagnetic water pump, during use, if outlet pipe 12 produces high pressure, and such as outlet conduit blocking, or water outlet is connected with high-tension apparatus, causes forming high-pressure area in outlet pipe 12.Safety check 9 glue head make outlet pipe 12 airtight due to external high pressure effect, if now Electromagnetic water pump continues pump water, current can be collected in valve pocket and outlet pipe 12, and cannot get rid of.When the pressure in outlet pipe 12 is enough large, working on of movable plunger assembly 4 can be hindered, cannot continue to pump into water from intake pipe 11.If now released by the pressure in valve pocket not in time, will directly cause the damage of Electromagnetic water pump.The utility model is owing to have employed Decompression valves 3, when the air pressure in outlet pipe 12 or hydraulic pressure are when increasing to a certain degree, glue head 32 will be pushed open, high-pressure air or water is made to discharge from the second air drain 341, along with the discharge of pressurized gas or water, Electromagnetic water pump just can pump water smoothly, can not cause the damage of Electromagnetic water pump.Simultaneously after the air pressure in outlet pipe 12 or hydraulic pressure reduce, under the second spring action, the second groove 102 blocks by glue head 32 again, prevents water from flowing out, and like this, Electromagnetic water pump is normally worked.
Certainly, the foregoing is only specific embodiment of the utility model, be not limit the utility model practical range, all equivalences done according to structure, feature and principle described in the utility model claim change or modify, and all should be included in the utility model claim.
