Description

Valve automatic opening-closing controller

Technical field

The utility model belongs to the operation equipment of valve in the engineering element, a kind of specifically valve water-saving controller that the switching of water valve in the water supply line is controlled automatically.

Background technique

Valve all is manually operated by the user in the water supply line of present many occasions, the user is often taken place because of a variety of causes throttle down situation not.For example, the manually-operated gate of the general user's control of the shower head in the shower house in the bathing pool is though have advantage of simple structure, troublesome poeration.In some common plunge baths for money, customers of a bathhouse are in normally open for the valve that just keeps easy to use after entering shower house in the time of many, not in shower head following time also flowing water in vain, cause the very big waste of hot water the people.According to statistics, people are after entering shower house, and the time that 40%--50% is arranged will be caused the waste of half nearly so not under shower head.Be head it off, the someone has invented a kind of pedal-type valve water-saving control gear, adopts perception shower head downforce to change and makes valve opening and closing, and its spoilage is higher, and human body feels more uncomfortable during use.The non-washed situation of user also often takes place in the flushing valve that also has communal bathroom to use, and has a strong impact on public health.

Summary of the invention

The present invention is intended to utilize human body to a kind of valve opening and closing automatic controller of infrared reflection principle design.Specifically, a kind of valve opening and closing automatic controller, it comprises the infrared inductor (21) of responding to human infrared signal, the infrared induction signal processing is converted into the drive circuit (15), drive motor (2) of motor (2) clockwise and anticlockwise signal and action and drive the shift fork (4) of valve handle (5) rotation under motor driving; Shift fork (4) links to each other with the output shaft (25) of motor (2), inductor (21) be contained in controlled valve after driving circuit board (15) links to each other near; One side of taking turns (12) at the motor of motor (2) is equipped with limit switch (24).

For the bigger valve of volume, its opening device changes gear into, for its coupling, can change shift fork (4) into be contained in motor output shaft (25) end gear.

Described drive circuit (15) comprises bridge rectifier, filter capacitor C, relay J 1, J2, the J3 that transformer B, D1-D4 form; The output terminal of bridge rectifier inserts the power input 1 of infrared inductor G, the power supply ground end 2 of infrared inductor G is cut-in relay J1, J2, J3 and motor M two ends respectively, infrared inductor signal output part 3 cut-in relay J1, connect with limit switch K1, K2 between three relays, indication light emitting diode D5, D6 and current-limiting resistance R1, R2 are connected on the motor two ends.

Described drive circuit (15) also has a delay circuit, meets adjustable resistance W on its 2 pin by IC, connects capacitor C 2 on 6 pin; And the point of the d in this circuit links to each other with G3 pin in the Drive and Control Circuit; The e point links to each other with the C point of J1 in the drive circuit.Install the valve opening and closing controller of delay circuit additional, be suitable for use in the control of urinal flushing valve.

The utility model is to utilize human body a kind of automatic type of infrared reflection principle design " people leak water pass, outage automatically " to be had the device of energy-saving and water-saving control.Only according to adding up in fountain, its water-saving rate can reach 44%.Power consumption only is 0.5 watt.

Working principle of the present utility model, utilize the reflected signal of human body to pass to receiving circuit, by control circuit VDC 24V is exported to synchronous machine, because motor rotates, convert electrical energy into mechanical energy and stir valve handle control valve realization pass water automatically with shift fork, the people walks automatically to cut off the water, and reaches the purpose of water saving.

Embodiment

Describe in detail according to the details and the working condition that the utility model proposes concrete device below in conjunction with Fig. 1-Fig. 3.

This infrared rays water saving controller comprises: socket piece (1), synchronous machine (2), stop screw (3), shift fork (4), water valve handle (5), shell (6), water intake (7), waterpipe jointing (8), water valve body (9), water outlet (10), motor runner (12), set screw (13), electric machine support (13), driving circuit board (15), infrared induction tutorial light (16), one-way valve (17), Cold water tap (18), hot-water valve (19), induction window (20), infrared inductor (21), incoming line (22), limit switch bracket (23), limit switch (24), motor shaft (25), touching screw (26) forms.

Among Fig. 4 and Fig. 5, J1, J2, J3 represent relay, and B indication transformer, BX are safety fuse cutout, D1-D4 forms bridge rectifier, C is a filter capacitor, and 1 is the infrared inductor power input, and 2 is the power supply ground end of infrared inductor, 3 is the infrared inductor signal output part, R1, R2 are respectively indication light emitting diode D5, D6 current-limiting resistance, and M is a motor, and K1, K2 are limit switch.

The 220V Ac is through the interchange 20V voltage of transformer B output, exchange 20V voltage through bridge rectifier D1～～D4 becomes the 24V VDC, gives infrared inductor and control relay J1 power supply respectively.

When the people enters induction region, infrared senor 3 pin output high level signal, the J1 adhesive of often making war, make the normal battle of J3 closed through the coil that limit switch K2 delivers to J3 high level, make motor b termination power high level, at this moment normally closed some adhesive of J2, a point connect the power supply negative terminal motor M and rotate, by the shift fork valve of fetching boiling water.
