Abstract
The utility model discloses an automatic switch contact device which utilizes water flows and water pressure to push a push rod to a drive magnetic block to suck a dry reed pipe for connection. The distance between the magnetic block and a water flow passage is increased to reduce the action of magnetic force, so that the blocking problem which is caused by rust stain and is easy to occur in work is solved. In a non-working state, a spring is utilized to ensure that the magnetic block is disengaged from the dry reed pipe to cut off the power. The utility model for pipe pumps is used in pressure automatic electric switches, particularly in the automatic switches of booster pumps which are domestic water pumps, and the using stability is favorable.
Description
The utility model relates to the mechanical type recloser, specifically a kind of automatic contact device of magnetic that utilizes current to promote.
In the prior art, be used for the recloser of hydraulic pressure suction booster, be designed to that the fire hose is first to be opened, when water flows, utilize hydraulic pressure that the electric path of water pump is connected.In its water stream tube door-revolving structure is set, drives magnetic patch when door-hinge rotates, make control contact adhesive, control of pump machine operation near dry reed-pipe.Shortcoming is: 1, the magnetic patch position is near water pipe, and attraction is gathered irony and caused that revolving door is stuck out of control easily; 2, door-hinge is tiny, easy deformation and cause malfunctioning.
The purpose of this utility model is that a kind of improved pipeline mounted pump recloser will be provided, and it can solve the fault of dirty obstruction of rust and door-hinge distortion well.
Said improved pipeline mounted pump recloser comprises valve body, magnetic patch and dry reed-pipe, it is characterized in that valve body is a three-port structure, and sealing is connected to cylindrical shell on the middle port, and the top, outside of cylindrical shell is provided with the dry reed-pipe that the control of pump circuit is used.Push rod is housed in the cylindrical shell uses pressure spring, under the effect of pipeline hydraulic pressure, move on the push rod with isolating, the top of push rod is embedded with magnetic patch, corresponding with the position at dry reed-pipe place, magnetic patch moves near the dry reed-pipe position with push rod and makes contacting in the pipe, makes pump working.The other end of push rod is away from magnetic patch, towards the flow channel of valve body.
In being provided with also in the said three-port structure form valve body that unsteady flow uses every, in every being provided with the variable flow channel hole of linking up A, two part tube chambers of B.
The utility model utilizes current hydraulic pressure to make on the push rod and moves, drive magnetic patch near dry reed-pipe, by magnetic force adhesive contact, thereby removed door-hinge, push rod length makes magnetic patch leave distance enough far away of current tube chamber, magnetic force is reduced to negligible degree to the effect of current, thereby has overcome the defect that contains the dirty blocking pipeline of iron rust that exists in the prior art effectively, has also therefore improved working stability and operating life.This apparatus structure is simple, rationally, pipeline mounted pump easy for installation, as to be equally applicable to other liquid streams.
Below be illustrated further combined with embodiment and accompanying drawing:
Accompanying drawing is the utility model embodiment's a structural representation.
Referring to accompanying drawing, the pipeline mounted pump recloser is made up of valve body 1 and the cylindrical shell 2 that is tightly connected with it.Cylindrical shell 2 is connected on the middle port of three-port structure.The dry reed-pipe 6 that the top of cylindrical shell 2 outsides is provided with, its lead-in wire is access to controller, in order to the power path of control of pump motor.Be provided with cylinder cover 7 above it.Push rod 3 and pressure spring 5 are arranged in cylindrical shell 2 tube chambers, and the push rod top is embedded with magnetic patch 4, and the position is corresponding with dry reed-pipe 6.Also be provided with in the tube chamber of valve body 1 a band flow channel hole 9 in every, in every playing directed unsteady flow usefulness, its flow velocity is suitably accelerated, in be divided into two parts of A, B every tube chamber with valve body, communicate through variable flow channel hole 9 therebetween.Establishing cavity in the push rod 3 is for economical with materials, the 8th, and the accent capping.
During work, open water tap, current enter A, and with push rod 3 jack-up upwards, spring 5 is compressed under water pressure pushing, and magnetic patch 4 makes its normally open contact closure near dry reed-pipes 6, external control loop is connected pump motor energising work.Water passes through from A to B, and the water pump that is connected in the path just can go the water pump extrusion.After water tap is closed, A part decompression, push rod 3 is withdrawing from back seat to variable flow channel hole 9 under the effect of spring 5, and magnetic patch 4 leaves dry reed-pipe 6 with push rod 3, and its normally opened contact restores to the original state, and the control access cuts off, the pump motor dead electricity, water pump quits work.Realize the recloser operation of water pump through said process.
Claims (2)
1, a kind of pipeline mounted pump recloser, comprise valve body (1), magnetic patch (4) and dry reed-pipe (6), it is characterized in that valve body (1) is a three-port structure, sealing is connected to cylindrical shell (2) on the middle port, the outside top end of cylindrical shell (2) is provided with dry reed-pipe (6), and push rod (3) and isolation pressure spring (5) are housed in the cylindrical shell (2), and magnetic patch (4) is located at the top of push rod (3), corresponding with the position of dry reed-pipe (6), the other end of push rod (3) is away from the flow channel of magnetic patch (4) towards valve body (1).
2, pipeline mounted pump recloser as claimed in claim 1, it is characterized in that also being provided with in the valve body (1) of said three-port structure form unsteady flow with in every, in every being provided with the variable flow channel hole of linking up A, two part tube chambers of B.
