Abstract
The utility model relates to an automatic switch for pipe pumps. A housing in which a water conveying channel and an isolating box are arranged is provided; a control circuit is arranged in the isolating box; the light transmitting pipe and the light receiving pipe devices of the control circuit are installed on both corresponding sides on the inner wall of the water conveying channel of the housing; a nonmetallic elastic valve sheet used for light shield is arranged between the two pipes. The pressure of water flows passing through the water conveying channel is utilized to tilt the elastic valve sheet, and a light path is opened to seizure signals to trigger bidirectional controlled silicon to control a pipe pump to work. The utility model with the advantages of no mechanical failure, favorable reliability and small size can be matched with various pipe pumps.
Description
The utility model relates to a kind of automatic pipeline pump switch, is various pipeline mounted pump adapteds.
The pipeline mounted pump that has earlier generally all adopts common electric switch to control, thereby to be used for family's shower supporting obviously be very inconvenient.For addressing this problem, a kind of spring pipeline mounted pump switch that in recent years manufacturer production arranged, it relies on the pressure-driven sensitive switch contact power contact of current in the water pipe, come the controlling plumbing fixtures pump work, but this kind structural type exists spring fatigue and mechanical wear, singe easily in the contact, thereby fault is more, poor reliability.
The purpose of this utility model is that a kind of pipeline mounted pump recloser will be provided, and it can reduce rate of fault effectively, improves reliability.
The utility model comprises housing and control circuit, it is characterized in that control circuit is made up of power circuit, photoelectric sensing circuit, bidirectional triode thyristor; Be provided with the cell of aqueduct and device circuit board in the described housing, the light-emitting tube of photoelectric sensing circuit and light receiving tube device are in the corresponding both sides of housing aqueduct inwall, the nonmetal valve block of one light blocking is arranged, with the light path between shading light emission tube and light receiving tube between two pipes.This recloser is fitted on the pipeline mounted pump, directly be connected during use with water pipe, after inserting power supply, when opening the valve block of water pipe, the water flow pressure in the water pipe is toppled over the spring valve plate Parallel to the flow direction, and promptly the light path between two pipes is by open-minded, the optical signal of light-emitting tube is searched by light receiving tube, the signal of searching triggers the bidirectional triode thyristor conducting after amplifying, pipeline mounted pump is worked because of connecting power supply.Otherwise, turn off the pipeline water valve, the water pipe current stop, and elastic valve plate resets, and light path is cut off and makes the bidirectional triode thyristor Triggerless and end, and pipeline mounted pump quits work because of dead electricity, thereby realizes the purpose of control automatically.
Therefore the utility model can not produce the mechanicalness fault owing to adopted photoelectric control circuit and nonmetal elastic valve plate, good reliability, and volume is little, can directly be fitted on the various pipeline mounted pumps, and easy to use with the pump integrator, practicability is good.
Fig. 1 is that the master that the utility model cooperates with pipeline mounted pump looks sectional view.
Fig. 2 is the utility model internal structure schematic representation (planimetric map).
Fig. 3 is a control circuit schematic diagram of the present utility model.
Do further describing of embodiment below in conjunction with accompanying drawing.The utility model has a housing (3), establish an aqueduct (1) and cell (5) in the housing, described control circuit is by power circuit (7), photoelectric sensing circuit (9), bidirectional triode thyristor (10) is formed, device is in the cell (5) of housing after being made into circuit board, light-emitting tube of photoelectric sensing circuit (9-1) and light receiving tube (9-2) (preferably adopt model BI-33, PP-EC301) device is in the corresponding both sides of housing aqueduct (1) inwall, the optical signal energy direct projection that guarantees emission tube is to receiving tube, establish the nonmetal elastic valve plate of a light blocking (2) between two pipes, can adopt a sheet rubber, a shading arm can be established in the top, its side plane area should can be isolated the emission tube light beam irradiates to receiving tube effectively greater than the beam diameter of emission tube ejaculation.
This recloser should be assembled into one with pipeline mounted pump (4), one power supply lead wire of electric motor for pump (8) is connected with the A end of 220V power supply and control circuit, another lead-in wire is connected with the B end of bidirectional triode thyristor (10), and the C of bidirectional triode thyristor holds the wherein line of direct 220V.For the utility model can be controlled automatically, can manually control again, between control circuit and 220V power supply, can insert a manual automatic selector switch (6), can realize simultaneously automatically and manually control.
Claims (3)
1, a kind of pipeline mounted pump recloser comprises housing and control circuit, it is characterized in that control circuit is made up of power circuit (7), photoelectric sensing circuit (9), bidirectional triode thyristor (10); Be provided with the cell (5) of aqueduct (1) and device circuit board in the described housing (3), light-emitting tube of photoelectric sensing circuit (9-1) and light receiving tube (9-2) device have the nonmetal elastic valve plate of a light blocking (2) in the corresponding both sides of housing aqueduct inwall between two pipes.
2, recloser as claimed in claim 1 is characterized in that nonmetal elastic valve plate (2) is a sheet rubber, and a shading arm is arranged at its top.
3, recloser as claimed in claim 1 or 2 is characterized in that going back and connecing on the described control circuit selector switch (6).
