Abstract
The utility model discloses an automatic control water valve, consisting of a motor, a deceleration system, a setting lever and a water valve; wherein the rotational axis of the motor(1) is made as the joggling of a worm(2) and a worm wheel(3), the worm wheel axis is provided with a small gear(4) which is joggled with a big gear(5); and the axis of the big gear is made into a screw(6), the setting lever(8) is fixed at a nut(70 which is coated with the screw; and the setting lever is movably connected with the handle of the water valve; the motion range of the setting lever is limited between two limited cylinder, the run forwards and the run backward of the motor is utilized to drive the setting lever to open and close the water valve; and the run forwards and the run backward of the motor is realized by a relay and the switch which switch the anode and the cathode of the power supply. Thereby the utility model has the advantages of simple structure, easy making, low cost, exact and reliable action, energy saving and wide use, in addition, safe and durable, etc; moreover, the utility model is capable of using a floating ball as the touching source, and adopting light control, time control, temperature control or remote manual control; thereby the automatic control water valve is suitable for being used in water tower, water pot and water tank, etc., in particular to be used in washer and solar energy water heater.
Description
(1) technical field
The utility model belongs to valve type, particularly a kind of automatic control water valve.
(2) background technique
The water valve that often uses has manually operated valve, float valve and solenoid valve etc. now.Manually operated valve is that people use water valve the earliest, this water valve operate the effort time-consuming.The float valve manufacturing process is simple, and cost is low, is usually used among pond, the water tower, thereby is to rely on the buoyancy of ball float to reach the purpose of closing or discharging water through shouldering bar and sheet rubber being compressed or unclamp.The sheet rubber of float valve utmost point and damaging under constantly collision and asymmetric extruding need the buoyancy of big (greater than hydraulic pressure from the beginning) just can compress sheet rubber simultaneously, so turn-off capacity is poor.Solenoid valve is a cone pin water valve, cone is pulled out the water valve breakdown after the electromagnet energising; Discharge cone after the electromagnet dead electricity, the pressured spring effect of cone compresses water outlet, and water valve cuts out.This water valve is strong by ability, and switching speed is fast, but needs to use the 220V civil power, and the continuous energising of electromagnet palpus could keep the opening state of water valve, therefore power consumption is big, and the easy burn-out coil of switching on for a long time, accuracy of manufacturing requires high simultaneously, cost is big, is easily stopped up by foreign material, can't generally use.
(3) summary of the invention
At the shortcoming of above-mentioned water valve, the purpose of this utility model is to develop the new type auto control water valve that a kind of cost is low, power consumption is little, purposes is wide, safe and reliable.
