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

Automatically control water valve

(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.

The technical solution of the utility model is such: control water valve automatically and be made up of motor, deceleration system, driving lever and water valve, utilize the motor forward or reverse to drive driving lever and open or close water valve, the motor forward or reverse is then realized by relay and switch Switching power both positive and negative polarity.The rotatingshaft of motor is made worm screw and is meshed with worm gear, small gear is installed on the worm-wheel shaft and is meshed with gearwheel, Large Gear Shaft During is made screw rod, is enclosed within to be fixed with driving lever on the nut on the screw rod and to live with the water valve handle to be connected, and the range of movement of driving lever is limited between two position limiting piles.The reverse touch switch S of duplex is housed respectively on two position limiting piles ₁And S ₂Switch S ₁Normally closed interlock as a contact of being touched district A, another normally closed interlock and two normally open contacts respectively with switch S ₂A normally closed interlock, normally open contact and relay J ₂Coil connectors connect.Switch S ₂Another normally closed interlock and relay J ₁On coil connectors connect, another normally open contact is as a contact of being touched district B.Relay J ₁And J ₂Another joint on the coil is connected with dc power cathode simultaneously.Relay J ₁Two groups of normally open contacts are arranged, and wherein two of an end contacts are connected with the DC electrical source both positive and negative polarity respectively.Relay J ₂3 groups of normally closed interlocks and 3 groups of normally open contacts are arranged, 3 normally open contacts respectively with switch S ₁On a normally open contact (connect S simultaneously ₂On a normally open contact), power cathode is connected with anodal; Contact is connected with positive source and motor the two poles of the earth respectively in the middle of 3; With connect corresponding two normally closed interlocks of power positive cathode then respectively with relay J ₁Two contact (J of the other end ₁Positive contact meets J ₂The normally closed interlock of negative pole correspondence) connects.Switch S ₁And S ₂The connecting line of normally closed interlock and relay J ₂Connecing anodal normally closed interlock connects.Being touched district A all is connected with positive source with another contact on the B.

Working principle of the present utility model is such: driving lever is in switch S ₁In the time of on the position, the water valve handle is in the closed position.Deliver to when activation signal and to be touched the district during A, two make contact on it, electric current passes through switch S ₁And S ₂Normally closed interlock arrives relay J ₁Coil, J ₁Action normally open contact closure is again through relay J ₂Normally closed interlock arrive motor, the motor forward rotation, by worm and worm gear and gear graduation, driving lever just with certain speed from switch S ₁To switch S ₂Move, stir the handle rotation, water valve begins to be opened.Touched district A this moment and lose to touch and make two contacts separately, driving lever leaves switch S simultaneously ₁After, S ₁Wraparound immediately: normally closed interlock disconnects, the normally open contact closure, but motor passes through switch S ₂Normally closed interlock and relay J ₁Self-locking action still be rotated further, move to switch S up to driving lever ₂, water valve is opened fully.Driving lever is parked in switch S ₂Place, S at this moment ₂Wraparound: normally closed interlock disconnects, normally open contact closure, relay J ₁Recover normally open, the motor stall, water valve is in opening state.Deliver to when activation signal and to be touched the district during B, two make contact on it, electric current passes through switch S ₂And S ₁(Bi He normally open contact) arrives relay J ₂Coil, J ₂Action: normally closed interlock disconnects, the normally open contact closure, and power positive cathode just is added on the motor in the opposite direction, and motor counter-rotating driving lever is from S ₂To S ₁Motion, water valve begins to cut out.Driving lever leaves S ₂After, S ₂Recover normal state, touched district B and also lose shake-up and make its two contact separation, motor passes through switch S ₁And relay J ₂Self-locking action continue counter-rotating, move to switch S up to driving lever ₁, water valve promptly is fully closed.Driving lever is parked in switch S ₁The place, S ₁Recover normal state, cut off motor power, water valve is in closed condition.So far, water valve unlatching, a pass closed procedure are finished.

The utlity model has simple in structurely, make easilier, cost is low, action accurately and reliably, little power consumption, purposes are wide, safety durable can be made advantages such as distant control.Water valve adopts porcelain heart valve, globe valve etc., available ball float control, and also available light-operated, time control or temperature control also can be adopted remote manual control.Be applicable to water inlets such as water tower, water tank, pond, be particularly suitable for using on washing machine and the solar water heater, also can be used for automatic irrigation and work such as water.
