Abstract
The utility model relates to a domestic automatic pipeline pressurizing pump. The utility model is formed by the common pressurizing pump provided with an automatic control structure. When the utility model is arrangedand used, a water valve is opened, an electric motor of the water pump runs, and the water pressure in the pipeline is increased. When the water valve is closed, the electric motor of a water pump stops working, the time is saved, the labor is saved, and the use is convenient. The utility model is integrated by the water pump and the automatic control sensor, and the utility model has the advantages of simple structure, sensitive control, reliable work and good sealing performance.
Description
The utility model relates to a kind of family expenses automatic pipeline booster pump.
Because there is the problem of subregion hydraulic pressure deficiency in China's urban water supply at present, especially building top layer hydraulic pressure is on the low side, make the resident who lives in this zone or floor water difficulties such as geyser occur normally to use, booster pump can solve this type of problem, but when using common booster pump, because the special circumstances of transience water (as shower etc.), can not open or close booster pump easily, therefore, automatic pressure pump is that people are required just.When automatic pressure pump uses, can reach with opening water valve and start the pump operation supercharging, close the purpose that water valve then switches off the pump.The control section of existing automatic pressure pump is made up of irregular magnetic valve, tongue tube, magnet etc. usually, moves because magnetic valve is done rotation, and changes of magnetic field is not obvious, influence control sensitivity, and its complex structure, and the assembling and setting difficulty is difficult to maintenance.
The purpose of this utility model is exactly in order to address the above problem, and a kind of advantages of simple, highly sensitive, reliable operation, good airproof performance, family expenses automatic pipeline booster pump easy to maintenance tied is provided.
Technical solution of the present utility model:
A kind of automatic pipeline booster pump, it is that water inlet flow channel corner bearing of trend design on common pipe booster pump water pump body has sliding valve structure.Sliding valve hole and water inlet flow channel, inlet opening, water pump center are three-way shape, their axis at grade, and this sliding valve hole and water inlet flow channel have a superposition section.Guiding valve is installed in the sliding valve hole, the sealing of one end, and inner chamber is installed with a magnetic patch, and a spring is installed, and the spring other end withstands on sealing screw inner chamber bottom surface.Between guiding valve and sliding valve hole certain interval is arranged, guiding valve can left and right sides translation in sliding valve hole, when right translation with the inner chamber of length of spring compressed at guiding valve and sealing screw.On the pump housing of the inlet channel outside, a rectangular slot is arranged, lay tongue tube seat and tongue tube and another magnetic patch in the groove, tongue tube is between two magnetic patch, and its axis is parallel with the sliding valve hole axis, draws two control lines from the tongue tube two ends and receives on the control circuit board in the water pump electrical equipment box.
The utility model and like product ratio, it is simple and compact for structure, owing to adopt the translational motion of magnetic guiding valve, add that its magnetic patch with the tongue tube opposite side cooperates, the tongue tube surrounding magnetic field is changed greatly and regular, be easy to debug the optimum position during assembling, make the tongue tube closure, disconnect the reflection sensitivity; Simultaneously,, during unlatching, have only after the enough distances of guiding valve translation and just open inlet channel, closed connection of tongue tube this moment because sliding valve hole has one section to overlap with water inlet flow channel; Equally, guiding valve return when closing, tongue tube disconnect the back guiding valve and also have return-stroke, guarantee that tongue tube disconnects, so control is reliable.Moreover the sliding valve hole source is by the sealing of sealing screw and plain cushion, makes this place good airproof performance and be convenient to keep in repair.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model guiding valve and tongue tube, magnetic patch relative position generalized section;
As figure, the utility model includes that water pump body 3, guiding valve 9, magnet 8, spring 15, sealing screw 16, sealing plain cushion pay 14, tongue tube seat 10, tongue tube 13, magnetic patch 12, draws two control lines 11 by the tongue tube two ends and is connected on the control circuit board in the water pump electrical equipment box 1.Characteristics of the present utility model are: at water pump body water inlet flow channel 4 corner bearing of trends one sliding valve hole 5 is arranged, this sliding valve hole inner cavity size has one section to overlap greater than the water inlet flow channel inner chamber and with it, sliding valve hole and water inlet flow channel, the 6 one-tenth three-way shape in inlet opening, water pump center.Guiding valve 9 is housed in the sliding valve hole, an end is installed magnet 8 in the guiding valve, the other end is equipped with spring 15, guiding valve can be in sliding valve hole move left and right, its axial location determines that by guiding valve left and right sides end face and sliding valve hole base frame rank and sealing screw left side spring was compressed in the inner chamber of guiding valve and sealing screw when guiding valve moved to right when mobile.
Operating principle of the present utility model is as follows: when the elastic force that promotes guiding valve 9 and magnet 8 by water inlet flow channel 4 and overcome spring 15 when the current of opening water valve lower pressure being arranged moves right slide valve assembly, tongue tube 13 surrounding magnetic fields change, tongue tube two contactings, the control electric current enters control circuit board by control line, pump motor is started, current enter in the pump through inlet opening, water pump center from inlet channel, and water pump begins supercharging work; When closing water valve, anhydrous flowing in the runner, under the spring force effect, the slide valve assembly return that moves to left, the tongue tube surrounding magnetic field recovers former state, and tongue tube two contact separation do not have the control electric current and enter control circuit, and pump motor is shut down, and water pump then quits work.
Claims (3)
1, a kind of family expenses automatic pipeline booster pump, guiding valve, tongue tube, magnet are installed on the pump housing, extend to design one sliding valve hole in water pump body water inlet flow channel corner, water inlet flow channel, inlet opening, water pump center are three-way shape on this sliding valve hole and the water pump body, and have one section to overlap with water inlet flow channel.Guiding valve can move back and forth in sliding valve hole, the sealing of guiding valve one end, and interior dress magnet, spring, the spring other end are against the sealing screw inner chamber bottom surface in sliding valve hole exit; After being compressed, spring contracts in the inner chamber of guiding valve and sealing screw composition.
2, family expenses automatic pipeline booster pump according to claim 1, thus the reciprocal translational motion of magnetic slide valve assembly in the pump housing is installed of its feature reaches tongue tube joint and disconnection control of pump is started and shutdown; Its radial location was definite by guiding valve outer wall and sliding valve hole inwall when guiding valve moved back and forth, and its axial location is limited by guiding valve both ends of the surface and sliding valve hole base frame rank and sliding valve hole exit sealing screw bottom face.
3, according to the described family expenses automatic pipeline of claim 1 booster pump, sliding valve hole, guiding valve, magnet can be circular, oval, square or other polygonal shape on its pump housing.
