Abstract

A non-pressure three-way electromagnetic valve comprises a valve bushing, and an inlet pipe orifice and two outlet pipe orifices on the bushing; the two outlet pipe orifices inside the bushing are respectively provided with a check valve. The utility model is characterized in that a movable permanent magnet is arranged between the two check valves; the outside of the valve bushing on the two ends of the inlet pipe orifice are respectively wound with a group of loop. The utility model is in particular applicable to a water supply system of a solar water heater in rural low water pressure zone, has simple structure, convenient installation and low cost.

Description

There is not the Three way type of pressure solenoid valve

(1) technical field:

The utility model belongs to a kind of solenoid valve, is specifically related to specialize in the rural area or is in a kind of nothing of using in the solar water heater water system in low hydraulic pressure area press three-way magnetic valve.

(2) background technique:

Mainly adopt the last water of single-pass electromagnetic valve controlling system at present in its water system of employed solar water heater of rural area, the single-pass solenoid valve mainly is made of valve component and coil block, spool one side in its valve component is provided with a returning spring, under of the effect of valve no electric circuit state lower valve core, be in position fixed ends, and be in the spool closed condition this moment at returning spring.The elastic force that the electromagnetic force that produces under the energising situation overcomes returning spring makes spool move to the other end fixed position, and that end of originally closing is in opening state, realizes the purpose of water on the control system thus.But in use find to exist following problems: because the no water service in most of area, rural area, general by digging well to get water, and the solenoid valve that this kind structure is installed needs just can to devote oneself to work under water-head is installed the condition of compression pump more greatly or in addition, therefore, use is restricted, and the manufacture cost height is installed.

(3) summary of the invention:

The purpose of this utility model just provides a kind of low to the requirement of water system pressure reduction, and last water speed is fast, the nothing simple, that cost is low is installed presses the Three way type solenoid valve.

There is not the Three way type of pressure solenoid valve, comprise a water inlet pipe mouth and two effluent pipe mouths on valve sleeve and the sleeve pipe, a safety check respectively is equipped with at two effluent pipe mouth places in sleeve pipe, it is characterized in that: between described two safety check, be provided with a removable permanent magnet, outside the valve sleeve of water inlet pipe mouth both sides, respectively be wound with one group of coil.

Characteristics of the present utility model are to need not to making bigger pressure difference rising water tower, and are easy to install, simple in structure, and low cost of manufacture is particularly suitable for using when solar water heater is installed in the low area of rural area or hydraulic pressure.

(4) description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model workflow schematic representation.

Among the figure: 1-valve sleeve, 2-water inlet pipe mouth, 3, the 4-effluent pipe mouth, 5, the 6-safety check, 7-permanent magnet, 8-coil, 9-water tower, 10-solar water container, 11-detecting head, 12-instrument, 13-solenoid valve, 14-water pump, 15-well, 16-safety check.

(5) embodiment:

Referring to Fig. 1, the utility model comprises valve sleeve 1, sleeve pipe is provided with Three way type water inlet pipe mouth 2 and

effluent pipe mouth

3,4, the water inlet and outlet mouth of pipe is the Three way type setting on valve sleeve, a

safety check

5,6 respectively is equipped with at two effluent pipe mouth places at sleeve pipe, be provided with a removable permanent magnet 7 between two safety check, outside the valve sleeve of water inlet pipe mouth both sides, respectively be wound with one group of coil 8.Working procedure of the present utility model is referring to Fig. 2, and when the drawdown in water tower 9 or the solar water container 10 need supply water, detecting head 11 separately can be to instrument 12 output water supply signals, and appliance circuit is respectively to solenoid valve 13 and water pump 14 input currents; The safety check 16 that is arranged on simultaneously between water pump and the well 15 is also opened, and water pump is started working.Meanwhile, the electromagnetic force that electromagnetic valve coil produces make in the valve sleeve permanent magnet to the left or the right side move, the direction that permanent magnet moves is by the current direction control of gauge internal circuit.If need to water tower water-feeding, the water tower probe output is given appliance circuit, and permanent magnet is moved to the right, and the electromagnetic force of its generation makes safety check 6 closures, and safety check 5 is opened, and water pump is to water tower water-feeding.After water supply finished, detecting head outputed signal to appliance circuit, and water pump and solenoid valve quit work, and at this moment, safety check 5 cuts out under the acting in opposition of current voluntarily, and safety check 16 also cuts out, and the water in the water tower can't flow backwards, and was anhydrous pressure condition in the solenoid valve valve pocket.If need to supply water in solar water container, detecting head outputs signal to appliance circuit, and permanent magnet is moved to the left, safety check 5 closures, and safety check 6 is opened, and water pump then supplies water in solar water container.So circulation, when water tower or solar water container water level equate or situation about not waiting under can both conveniently supply water.The utility model really can reach described technique effect through on probation.

Claims

1. there is not the Three way type of pressure solenoid valve, comprise a water inlet pipe mouth and two effluent pipe mouths on valve sleeve and the sleeve pipe, a safety check respectively is equipped with at two effluent pipe mouth places in sleeve pipe, it is characterized in that: between described two safety check, be provided with a removable permanent magnet, outside the valve sleeve of water inlet pipe mouth both sides, respectively be wound with one group of coil.
