Abstract

The utility model provides an automatic switch for a pipeline pump, which comprises a hinged door which is arranged in a pipeline and driven by water stream, and a spring which is arranged at the back side of the hinged door and drives the hinged door to be reset, wherein a door shaft of the hinged door is provided with a magnetic plate which follows the door shaft to rotate, and a permanent magnet is arranged in the magnetic plate; an isolation plate is arranged between the hinged door and the magnetic plate; an isolation chamber which is arranged in a reed pipe is arranged above the magnetic plate, and the magnetic plate controls the isolation chamber to be opened and closed. When a valve is opened, the magnetic plate follows the hinged door pushed by the water flow to rotate and be close to the reed pipe to make the reed pipe conduct a circuit of a motor in a closed way. When the valve is closed, the magnetic plate moves away from the reed pipe to cut off the circuit of the motor. Thus, the utility model can be linked with the valve.

Description

The pipeline mounted pump recloser

The utility model relates to a kind of pipeline mounted pump recloser.

Under-voltage pipeline will be provided with pipeline mounted pump and come the convection cell supercharging, during use, generally when will opening, ducted valve or tap start the pipeline mounted pump running, when throttle down or tap, pipeline mounted pump then will shut down, and the controlling plumbing fixtures pump work is hand switch, obviously, in the under-voltage pipeline of pipeline mounted pump has been installed, so use pipeline mounted pump not only cumbersome, and cause the situation of having closed valve but not closed pump easily.

The purpose of this utility model provides a kind of pipeline mounted pump recloser.

This pipeline mounted pump recloser has to be arranged on the ducted hinge door that is promoted by current and to be arranged on the hinge door rear side and promotes the spring that hinge door resets, the magnetic sheet of the interior dress permanent magnet that rotates with door-hinge also is housed on the door-hinge of hinge door, and hinge door is with being provided with isolating plate between the magnetic sheet, dress was controlled the isolation ward of the dry reed-pipe of its folding in the top of magnetic sheet was provided with by magnetic sheet.

Dry reed-pipe is added in the motor circuit that quenching resistor is series at pipeline mounted pump, when valve in the opening conduits or tap, the water that flows promptly promotes hinge door and rotates, magnetic sheet is also thereupon near dry reed-pipe, and making the closed conducting motor circuit of dry reed-pipe, pipeline mounted pump starts, when throttle down or tap, water stops to flow, hinge door promptly resets under the effect of spring, and magnetic sheet also leaves dry reed-pipe thereupon, and the reed in the dry reed-pipe promptly flicks the cut-out motor circuit, the pipeline mounted pump stall, this shows that the utility model can realize that pipeline mounted pump links with valve, by opening or closing of valve, automatically the work of controlling plumbing fixtures pump is easy to use.

Illustrate detailed content of the present utility model below in conjunction with drawings and Examples.

Fig. 1: structural drawing of the present utility model;

Fig. 2: A-A sectional view;

Fig. 3: door-hinge component drawings.

As shown in the figure, pipeline mounted pump recloser described in the utility model has to be arranged on the hinge door 2 that is promoted by current in the pipeline 1 and to be arranged on hinge door 2 rear sides and promotes the spring 3 that hinge door resets, the magnetic sheet 6 of the interior dress permanent magnet 5 that rotates with door-hinge 4 also is housed on the door-hinge 4 of hinge door 2, and hinge door 2 is with being provided with isolating plate 7 between the magnetic sheet 6, dress was by the isolation ward 9 of the dry reed-pipe 8 of magnetic sheet 6 its foldings of control in the top of magnetic sheet 7 was provided with.The spring 3 of present embodiment adopts pressure spring, again hinge door 2, door-hinge 4 and magnetic sheet 6 are designed to one, and it is assembled in the housing 10 of a left and right opening together with spring 3, be set in pipeline 1 by housing 10 then, hinge door 2, door-hinge 4 and spring 3 are positioned among the pipeline 1.The isolation ward 9 that this enforcement will be held the cavity 11 of magnetic sheet 6 and hold dry reed-pipe 8 is designed to one and seals housing 12, after it is closed up with pipeline 1, by sealing housing 12 isolating plate 7 and housing 10 are pressed in the pipeline 1, sealing the upper cover upper cover 13 of housing 12, dry reed-pipe 8 promptly is closed in the isolation ward 9, and two leads of dry reed-pipe 8 then stretch out from isolation ward 9.In addition, at the two ends of pipeline 1 connecting thread is set with the linkage structure of pipe by pipe.Seal ring 14 to be set sealing the connection mouth of housing 12 with pipeline 1.

Claims

1, a kind of pipeline mounted pump recloser, it is characterized in that: have and be arranged on the hinge door (2) that promotes by current in the pipeline (1) and be arranged on the spring (3) that hinge door (2) rear side promotion hinge door resets, the magnetic sheet (6) of the interior dress permanent magnet (5) that rotates with door-hinge (4) also is housed on the door-hinge (4) of hinge door (2), and be provided with isolating plate (7) between the same magnetic sheet of hinge door (2) (6), dress was controlled the isolation ward in reed pipe (8) (9) of its folding in the top of magnetic sheet (7) was provided with by magnetic sheet (6).
