Abstract
The utility model provides an electromagnetic valve, which comprises a valve body provided with a fluid passageway, a valve core arranged in the valve body and a coil arranged at the upper part of the valve core. The utility model is characterized in that an air inlet is arranged above a fluid outlet of the valve body, and a groove is arranged on the valve core corresponding to the air inlet. When electromagnetic valve is closed, air can enter the valve, remained water in a pipe can be pressed out. When the electromagnetic valve is opened again, solar hot water can be used as opened. The operation of discharging cold water first and discharging hot water then is not needed, and the phenomenon that the solar hot water remains in a pipeline is avoided. Water resources are saved, and simultaneously, the phenomenon that the pipeline expands to be cracked by frost due to the freezing of water in winter. The service life of the pipeline is extended, and the utility model also has the characteristics of simple structure, low cost, high work efficiency, etc. and is an ideal electromagnetic valve which can lead remained water not to exist in the pipeline.
Description
Technical field
The utility model relates to a kind of solenoid valve, belongs to the design and the manufacturing technology field of electromechanical valve.
Background technique
At present, the solar water heater that is widely used is installed in the roof or is higher than the place in room, introduces hot water indoor and is controlled with hot-water valve by pipeline.Because hot-water valve all is contained in indoor place easy to use, thereby make solar energy hot water tank in this section aqueduct, leave Yu Shui with water spot, when causing opening the valve water at every turn, all to will just there be hot water to flow out after the surplus water of empty calory has been put in the pipeline, thereby causes the waste of valuable water resources.If use closing of general solenoid valve control hot water instead, then will allow the atmospheric pressure that conduit pipe bears to be increased with hydraulic pressure value, and this pressure can only lean on the reverse air of hot water outlet to reduce pressure, this is very unfavorable.So, be necessary existing solenoid valve is improved.
Summary of the invention
For the surplus water in the solar water heater delivery pipeline can all be flowed out, to avoid causing the waste of water resources, and after opening hot water is flowed out immediately, the utility model provides a kind of water-saving solenoid valve.
The utility model is finished by following technical proposal: a kind of solenoid valve, comprise the valve body of being with stream socket, place the spool in the valve body, place the coil on spool top, the fluid output top that it is characterized in that valve body is provided with suction port, and the spool corresponding with this suction port is provided with groove.So that when valve opening, be communicated with water intake with water outlet and suction port is closed in entry simultaneously, otherwise when valve closing, open suction port, suction port is communicated with water outlet, all extrude thereby will manage interior surplus water.
Groove groove footpath on the described spool so that behind the valve closing, can make air enter in the pipe greater than valve body suction port bore.
The utility model compared with prior art has the following advantages: adopt such scheme, can air be entered in the valve, thereby the surplus hydraulic pressure in will managing goes out, when opens solenoid valve once more, can make the solar water plug and play, need not to put earlier cold water reusable heat water, avoided remaining solar water in the pipeline, both saved water resources, and can effectively prevent that winter, pipeline expanded by bursting by freezing the working life of prolongation pipeline because of water freezing simultaneously again, the utility model also has simple in structure, cost is low, and characteristics such as working efficiency height in fact are the solenoid valve of a desirable pipeline nothing left water.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, is not limited in this but hold within the utility model.
As shown in Figure 1, spool 2 is installed in the electromagnetic valve body 1, spool 2 tops are passed valve body and are placed in the electromagnetic coil 4, and coil 4 links to each other with power supply by lead-in wire 5, switch 6, is provided with spring 3 between spool 2 tops and the valve body 1, spool 2 bottoms are provided with groove 8, on the valve body 1 corresponding, be provided with suction port 7, when closing valve, promptly form gas-entered passageway between suction port 7, groove 8, the water outlet 9 with groove 8, enter in the valve in the pipe so that air enters, 10 is the water intake on the valve body again.Closed power switch 6, electromagnetic coil 4 produce magnetic field and drive spool 2 risings, and close suction port 7 this moment, opens valve, and water enters from water intake 1, flow out through water outlet 2.Disconnecting power switch 6, electromagnetic coil 4 magnetic fields disappear, and spool 2 moves down and closes in spring 3 effects, opens suction port 7 simultaneously air is entered, thereby the hydraulic pressure in water outlet 9 and the pipe is gone out.
Claims (2)
1, a kind of solenoid valve comprises the valve body of being with stream socket, places the spool in the valve body, places the coil on spool top, it is characterized in that the fluid output top of valve body is provided with suction port, and the spool corresponding with this suction port is provided with groove.
2, solenoid valve according to claim 1 is characterized in that groove groove footpath on the described spool is greater than valve body suction port bore.
