Description

The automatic miniature suction booster

The utility model relates to a kind of automatic miniature suction booster.

Along with improving constantly of living standards of the people, various household water heaters enter huge numbers of families, but owing to present China part town dweller especially building top layer resident family exists water supply pressure on the low side, solar water heater occurs and can not go up water, gas water-heater ignition difficulties, phenomenon that the electric water heater water-outlet quantity is little, the automatic miniature suction booster can solve this class problem.When automatic pressure pump is installed and used, only need open the supercharging of promptly turning round of water valve water pump, close the water valve water pump and quit work, especially when taking a shower, need not the switch pump power, easy to operate, time saving and energy saving.Existing automatic pressure pump, major part are to connect an automated sensor at common suction booster water intake or water outlet, make installation dimension long and complicated; In addition, the magnetic valve original paper of general automatic pressure pump directly places runner, and iron rust impurity in the pipeline is adsorbed in unshielded measure easily, and make that valve is stuck and lose automatic function, thereby the rate of fault height, maintenance difficult; Moreover, because the water pump intake-outlet is offset to the pump housing, be difficult to adopt " water meter formula " directly to be installed in the pipeline.

The purpose of this utility model is exactly for addressing the above problem, and provides a kind of and has anti-iron rust impurity function, the intake-outlet line is positioned at the miniature vortex suction booster of automatic integration on the symmetry plane of water pump center.

Technical solution of the present utility model:

A kind of automatic miniature suction booster adopts the peripheral pump working principle, and its intake-outlet center line is on same straight line, and by water pump center symmetry plane; Water inlet flow channel is guided the water pump bottom by water intake into through a chute, bottom flow passage strides across water pump center to water outlet one side and leads to water pump inside, this bottom flow passage is made of one section cylindrical hole and a cylindrical hole and a rectangular groove combination inner chamber, the cylindrical hole right-hand member has a tapped hole, and the water control spool member is installed in this tapped hole; Spool member is made up of sleeve valve, spring, sealing bolt, seal ring, bolt bottom, rubber guard shield and ring magnet.Guiding valve left end big column places in the pump housing cylindrical hole runner, and a cylindrical spring is housed on the mediate cylindrical, and this cylindrical spring left end withstands on guiding valve big column inner side surface, and right-hand member withstands on the bolt bottom; Guiding valve right-hand member one round bar center hole on the bolt bottom stretches into the sealing bolt inner chamber, and round bar tightens an annular magnetic patch is installed in this chamber; Annular magnetic patch and guiding valve are formed slide valve assembly, slide valve assembly can be in pump housing runner and bolt inner chamber move left and right, its position that moves to left is determined that by guiding valve big column outer side surface and the pump housing cylindrical hole runner left side position that moves to right is determined by raised head face in the middle of cylinder step in the guiding valve and the bolt bottom.On the boss rubber guard shield is housed in the middle of the bolt bottom, to prevent that iron rust impurity from entering that the sealing bolt inner chamber is adsorbed on the magnet and stuck guiding valve.Design has a rectangular slot on the pump housing of the spool member outside, and the dry reed-pipe seat is installed in the groove, is equipped with dry reed-pipe and another magnetic patch on the seat; Dry reed-pipe is on this magnetic patch and the guiding valve between the annular magnetic patch, its axis and slide valve spindle line parallel; Drawing two guide lines from the dry reed-pipe two ends receives on the control circuit board in the suction booster electrical equipment box.

The utility model constitutes the integral type automatic pump with like product ratio, automatic control original paper design and installation on the pump housing; The intake-outlet center line makes that on the same straight line and on the water pump symmetry plane installation is simple and convenient, and sealing is reliable; Magnet left and right sides translation in the sealing bolt inner chamber of sealing is not subjected to iron rust impurity effect in the water, and rate of fault is little, and is highly sensitive, and Installation and Debugging are convenient; Turn sealing bolt, can pull down spool member separately, be convenient to maintaining; Adopt the peripheral pump working principle, the utility model compact structure, volume is little, the lift height.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model spool member, dry reed-pipe, magnet relative position schematic representation;

As figure, the utility model includes the pump housing 3, guiding valve 9, ring magnet 15, sealing bolt 19, bolt bottom 15, rubber guard shield 12, cylindrical spring 8, dry reed-pipe seat 17, dry reed-pipe 13, magnetic patch 14, draws two guide lines 2 from the dry reed-pipe two ends and receives on the control circuit board in the electrical equipment box 1.Structural feature of the present utility model is: guide pump housing bottom flow passage from water intake into by a chute 4, this runner left end is a cylindrical hole, the centre is a cylindrical hole and a rectangular recess 5 combination inner chambers, this combination inner chamber strides across the water pump center to the water pump opposite side, has a passage at the rectangular recess end face and leads to water pump inside; At the bottom flow passage right-hand member is an interior threaded hole, installing and fixing sealing bolt and spool member, and by seal ring 18 sealings.Guiding valve 9 left ends are a big column, and the centre is a small column and round bar, and the round bar left end passes bolt bottom center hole and stretches in the sealing bolt inner chamber 19, and it tightens an intrinsic ring magnet 15, and this ring magnet can be with the guiding valve move left and right; Its axially locating determines that by guiding valve big column exterior edge face and pump housing runner cylindrical hole left side 10 its location is determined by small column step 11 in the middle of the guiding valve and bolt bottom boss left side when moving to right when moving to left.Cylindrical spring 8 was compressed between guiding valve big column right side and the bolt bottom left side when slide valve assembly moved to right.

Working principle of the present utility model is as follows: the current of lower pressure are arranged through water inlet chute 4 when opening water valve, when promoting on the guiding valve 9 big column and overcoming spring force slide valve assembly is moved right, dry reed-pipe 13 surrounding magnetic field intensity change, the dry reed-pipe intermediate contact is connected, the control electric current enters control circuit board through guide line, make that controllable silicon touches the three-way motor main circuit on the circuit board, pump motor starts, current enter the water pump internal pressurization from water inlet chute 4 through pump housing bottom flow passage cylindrical hole to rectangular recess 5, the current that are pressurized extrude from water outlet 6, and water pump promptly 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 dry reed-pipe surrounding magnetic field recovers former state, and reed switch contact separates, no current enters control circuit, the outage of motor main circuit, suction booster quits work, and controls the suction booster running supercharging or the purpose that quits work automatically thereby reach by current.
