Like this, the utility model is significantly swung along the dry reed-pipe direction by magnet, has increased displacement, and dry reed-pipe is disconnected and the adhesive sensitivity, has improved the working sensitivity of The whole control switch and pipeline mounted pump.Actuating member and the magnet of being made up of support, blade, link fuses in addition, is convenient to install and change.

Below, given in conjunction with the accompanying drawings embodiment does detailed explanation to the utility model:

Fig. 1 is a kind of embodiment's of the utility model a sectional view;

Fig. 2 is the schematic sectional view along the A-A direction of Fig. 1.

As Fig. 1, shown in Figure 2, pipeline mounted pump recloser of the present utility model, comprise the passage component 1 that links to each other with pipeline, actuating member 2 and switch controlling component 3, be provided with liquid chunnel in the passage component 1, switch controlling component 3 comprises magnet 4 and magnet controlled electronic switch 5, magnet controlled electronic switch one end is connected with power supply 6, the other end is connected with pump motor 7, switch controlling component 3 is contained in the switch capsule 8, switch capsule 8 is contained in outside the passage component 1, it is characterized in that: actuating member 2 comprises the support 21 that has a through flow hole 211, place the blade 22 of this through flow hole, the link 23 that connects blade 22 and described magnet 4, this link passes the dividing plate 212 that is located in the support and is supported on rotationally on the described support 21, actuating member 2 one ends link to each other with switch capsule 8, and the other end stretches in the liquid chunnel of described passage component 1.

Described support 21 is cylindrical substantially (also can to adopt other shapes as required, for example square), the part that stretches in described passage component 1 liquid chunnel has a Closed End, an end that links to each other with switch capsule 8 and described through flow hole 211 perpendicular directions are formed with two axis holes 213, be formed with two gudgeons 231 on the described link 23, this two gudgeon 231 cuts with scissors by (also can adopt other modes that link and support are hinged as required) mutually with described two axis holes 213.The W of Fig. 1 is to being water (flow) direction, when the current in the passage component 8 produce specific flow differential pressure, the pipeline valve (not drawing among the figure) that for example will be contained in the left side of passage component 1 shown in Figure 1 is when opening, blade 22 is under the impact of current, produce an active force, make blade drive link 23 and rotate that rotation amplitude is shown in the double dot dash line of Fig. 1 around the gudgeon in its rack shaft hole 213 231.

The position of the contiguous described dividing plate 212 lip ring mounting groove 214 that is shaped is equipped with a close annex 24 of rubber on the support 21 in the sealing part mounting groove, and described link 23 passes this close annex center through hole 241.The sealing groove can be taked different sectional shapes as required, and present embodiment adopts circular.This close annex can prevent that impurity enters in the magnetic control chamber 82 that links to each other with support 21 in the sealing from the through hole 215 of dividing plate central authorities.

In the through flow hole 211 on the described support 21 without leave water intake increase the sectional shape of this through hole and described blade 22 shape broadly similars, and guarantee to have enough big gap between blade 22 and the through flow hole 211 gradually to the water outlet direction.This structure can make blade sensing differential pressure sensitivity on the one hand, and current are unobstructed in the time of can making the pump working supercharging on the other hand, the position in the time of also can limiting blade and reset.

Switch capsule 8 is divided into an electronic switch chamber 81 and a magnetic control chamber 82 by an isolating plate 812, and described magnet controlled electronic switch 5 is contained in that this electronic switch is indoor, and it is indoor that described magnet 4 is contained in this magnetic control, and magnetic control chamber and described support 21 are tightly connected.Can make electrical equipment original paper in the magnet controlled electronic switch 5 avoid the erosion of water like this, also because the effect of above-mentioned dividing plate 212 and Sealing 24 is arranged, it is more abundant that magnetic control chamber and current are isolated, and the absorption of stopping the magnetic substance in 4 pairs of current of magnetic control chamber 82 inner magnets substantially guarantees the switch proper functioning.

Be formed with a flange 83 on the switch capsule 8, passage component 1 is provided with corresponding flange 11, two flanges and is inter-connected via a bolt joint together, is convenient to install.

Described magnetic control chamber 82 is inlaid with a magnetic metal sheet or the small magnet 41 inhaled mutually with described magnet 4 in the end wall of water outlet direction one end.When the current in the passage component 1 remain static, when the blade both sides do not have pressure reduction, make link 23 drive blades 22 under the magnetic force of 41 of magnet 4 and magnetic metal or small magnets and be returned to original position (position shown in Figure 1).

Described electronic switch chamber 81 is one can draw the enclosed cavity of lead, is full of insulating medium in this cavity, can select for use different medium, the utility model to select economic waste or used plastics for use as required.Can play insulating effect, also can support each electrical equipment original paper of magnet controlled recloser.

Magnet controlled electronic switch 5 comprises dry reed-pipe 51, controllable silicon 52 and resistance 53, dry reed-pipe, controllable silicon and resistance link together by lead, magnet 4 is adjacent with dry reed-pipe 51, when link 23 when its gudgeon 231 rotates, driving magnet 4 moves along dry reed-pipe 51 directions, this magnet controlled ON-OFF control circuit and principle thereof are that those of ordinary skill in the art is known, are not giving unnecessary details herein.

Described support 21, blade 22, link 23 and switch capsule 8 are made of plastic, and be light and be convenient to make.

As seen, the utility model pipeline mounted pump recloser, under the effect of particular water amount or differential water pressures, blade 22 drives link 23 and rotates around gudgeon 231, promptly the axis that winds perpendicular to paper of link that solid line is drawn 23 goes to position shown in the dot and dash line clockwise as shown in Figure 1, drives the magnet 4 that connects together with link 23 simultaneously and moves along dry reed-pipe 51 directions, thereby trigger dry reed-pipe 51 adhesives, make controllable silicon 52 conductings, connect pump power; After the water flow differential pressure is reduced to setting value, under the tinsel or the suction between small magnet in magnet 4 and switch capsule 8 walls, make link 23 drive blade and return back to position shown in the solid line from dot and dash line inverse position hour hands shown in Figure 1, dry reed-pipe is disconnected, cut off pump power, water pump quits work, thereby utilizes the automatic control of the flow differential pressure realization of current to water pump.

The foregoing description is the usefulness of explanation the utility model only, and is not to be to restriction of the present utility model, and the those of ordinary skill in relevant field can also be made various variations or modification on this basis, and protection domain of the present utility model should be as the criterion with claim.
