Abstract
The utility model relates to an automatic shutoff device for a valve, which is composed of a power supply, a direct current motor, a control circuit, a motor switch, a retarding mechanism and a wire spool. A direct current motor shaft is connected with the retarding mechanism, the wire spool is arranged on the output shaft of the retarding mechanism, and a cable on the wire spool is connected with the valve rod of the valve through a connecting rod; a normally closed spring leaf and a signal socket are arranged on the control circuit, one sheet of the normally closed spring leaf is extended to the motion track of the cable, and a device for driving the operation of the spring leaf is arranged at the corresponding position between the cable and the shutoff position of the valve. The utility model which provides convenience to users, can shut off a valve automatically and can save water.
Description
The utility model relates to a kind of valve automatic controller, especially with the self-closing device of the valve of valve rod.
Solar water heater has been widely used in enterprises and institutions and family now.Establish intake pipe and on domestic solar water heater's water tank and cause indoor spill pipe, during water inlet, people can't know when water tank advances full water.There are flowing out in spill pipe, people just know and have advanced full water in the water tank, thereby close inlet valve.In the said process, people can not leave spill pipe, because do not note slightly, and will be because of in time not closing the waste that inlet valve causes water.
The purpose of this utility model is exactly at the problems referred to above, designs a kind of valve self-closing device, and when water tank advanced full water, this device energy automatic-closing valve had made things convenient for the user, and saved water.
The purpose of this utility model is realized by following technical proposals:
Form by circuit, motor switch, reducing gear, wire spool that power supply, direct current generator, control direct current generator rotate, the direct current arbor links to each other with reducing gear, hawser on the wire spool links to each other with the spanner of valve, establish a normally closed reed and signal socket on the circuit that the control direct current generator rotates, a slice in the normally closed reed extends on the movement locus of hawser, establishes the device that drives the reed action corresponding to the valve closing position on the hawser.Driving component in the reducing gear is a gear.The device that drives the reed action is along hawser protrusion radially.The signal socket inserts 1 signaling line, and two line end heads that the end of signaling line is exposed are located at the water tank inner top.
Working principle of the present utility model is such:
When intaking to solar water heater water tank, the user opens inlet valve with hand.When advancing full water in the water tank, the line end head of signaling line immerses in the water, circuit turn-on, and motor rotates, and rotates by reducing gear driving wire spool, and hawser toward reclaiming, is moved to the direction of throttle down thereby drive valve key.Behind valve closing, the protrusion of the driving reed action on the hawser forces normally closed reed separately, and circuit disconnects, the motor stall, and valve closing finishes.Thereby realization automatic-closing valve.
Technical characteristics of the present utility model and good effect:
The utility model is simple in structure, is easy to make.Not only can be automatically throttle down fully, and can pass through switch manual-lock valve.Because the driving component in the reducing gear is a gear, so this device does not influence manually opened valve.This device is not only convenient and practical, and has saved water.If the opposite side at valve key is installed a same controller, can realize the electronic valve of opening.
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is done further narration:
Accompanying drawing is a structural representation of the present utility model.
1 is power supply, the 2nd among the figure, control circuit, the 3rd, and direct current generator, the 4th, reducing gear, the 5th, wire spool, the 6th, hawser, the 7th, casing, the 8th drives the spheroid, the 9th that reed moves, connecting rod, the 10th, normally closed reed the 1, the 11st, signal socket, the 12nd, motor switch.As shown in the figure, the utility model is made up of power supply, control circuit 2, direct current generator 3, motor switch 12, reducing gear 4, wire spool 5, the axle of direct current generator 3 links to each other with reducing gear 4, and the hawser 6 on the wire spool 5 links to each other with connecting rod 9, and connecting rod 9 links to each other with the valve rod of valve.Establish a normally closed reed 10 and a signal socket 11 on the control circuit 2.A slice in the reed 9 extends on hawser 6 movement locus, establishes the spheroid 8 that drives the reed action corresponding to the valve closing position on the hawser 6.
Claims (3)
1, a kind of valve automatic controller, it is characterized in that it is made up of circuit, motor switch, reducing gear, wire spool that power supply, direct current generator, control direct current generator rotate, the direct current arbor links to each other with reducing gear, wire spool is located on the output shaft of reducing gear, hawser on the wire spool links to each other with the spanner of valve by connecting rod, establish a normally closed reed and signal socket on the circuit that the control direct current generator rotates, a slice in the normally closed reed extends on the movement locus of hawser, establishes the device that drives the reed action corresponding to the valve closing position on the hawser.
2, a kind of valve automatic controller of narrating according to claim 1 is characterized in that the driving component in the reducing gear is a gear.
3, a kind of valve automatic controller of narrating according to claim 1, the device that it is characterized in that driving the reed action is along hawser protrusion radially.
