Description

The timing controlled irrigation valve

Technical field

The present invention relates to a kind of timing controlled irrigation valve, be specifically related to a kind ofly can set the operating time, the irrigation valve of regularly closing.

Background technique

Agricultural irrigation water meter in the market divides two types of common water meter and IC-card intellectual water meters: IC-card intellectual water meter or IC-card charging water meter mainly are made up of valve, flow transducer, microprocessor, IC-card read/write device, display device and power supply etc.The IC-card sheet that will contain the amount of money injects the IC-card read write line in the water meter, after computer module identification and downloading the amount of money, and valve opening, the user is water normally.When user's water, water yield collecting device begins water consumption is gathered, and converts required electronic signal to and supply with computer module and measure, and on the LCD display modular, shows.When user's the water amount of money dropped to certain numerical value, computer module carried out sound alarm, and the prompting user should go that holding pays dues purchases water.As surpassing the water amount of money, then computer module can be closed electric control valve automatically, cuts off and supplies water.Inserting the IC-card sheet paid dues until the user restarts Open valve and supplies water.Though the IC-card intellectual water meter can reach the target of quantitative control water, the market price is too high, and peasant household does not generally afford to do; And common water meter is made up of watchcase, adapter, collection gear, pressure cover, watch crystal.The water impact impeller, thus the pointer that impeller driven gear unit drives on the dial plate rotates, to show Total Water.But only can not possess quantitatively or the timing irrigation function as the water consumption measurement instrument, wherein also there are a large amount of wastes of human resources in controlling unit.

Summary of the invention

But the timing controlled irrigation valve of the purpose of this invention is to provide a kind of set time, regularly closing.

A kind of timing controlled irrigation valve provided by the invention comprises sealed cavity, timing control apparatus and water outlet controller for opening and closing;

The sidewall of said sealed cavity is provided with water intake and water outlet;

Said timing control apparatus comprises gear assembly and the rotary switch that is connected with this gear assembly, and said rotary switch is provided with the time dial plate; Said timing control apparatus is located on the top of said sealed cavity;

Said water outlet controller for opening and closing comprises linkage part, push rod and spring; Said linkage part comprises round Short Item, sector ele-ment and torsion spring; Said round Short Item is for to cut the element with arc orbit that a cattle horn shape partly obtains by circular element from its edge, and the radius of said circular element equates with the radius of said sector ele-ment; Said sector ele-ment is located on the said round Short Item and the center of circle overlaps; One end of said torsion spring is fixed on the said sector ele-ment, and the other end is fixed on the said round Short Item; One end of said push rod is connected with said spring through a plug, and said spring and plug are located at outside the said water outlet, and said plug can be sealed and matched with said water outlet; The other end of said push rod can match with the breach that forms between said round Short Item and the sector ele-ment;

Said gear assembly is connected through connecting rod with said round Short Item.

When using above-mentioned timing controlled irrigation valve to carry out timing, the user can according to the time scale on the said time dial plate, rotate said rotary switch to respective value as required, and said rotary switch can drive said gear assembly, tightens clockwork spring; Then, said rotary switch begins slow revolution under the drive of gear assembly, promptly carries out countdown.

In the above-mentioned timing controlled irrigation valve, can be provided with rubber cushion between said gear assembly and the said connecting rod, can prevent that current from getting into the inside of said gear assembly; Can be provided with rubber cushion on said plug and the face that said water outlet matches, can make the closure effect between said plug and the water outlet better.

In the above-mentioned timing controlled irrigation valve, said torsion spring can be fixed on said round Short Item and the sector ele-ment through set screw.

The present invention has the following advantages owing to take above technological scheme: 1, timing control apparatus, linkage part, push rod and the spring through pure machinery waits the purpose that reaches the timing controlled irrigation, and whole process does not have other resource consumption, clean and effective; 2, with the electronic control system of the former moving system of simple spring, the complex and expensive of gear assembly replacement cleverly, with low cost, easy and simple to handle, easy to maintenance; 3, the operator can give crop with pouring regularly with reference to the scientific experiment data according to weather condition, the crop growth period on the same day, makes management accurately, is guaranteeing to make the water resources utilization more efficient under the situation that crop needs water to satisfy; 4, the operator just can leave after having set the time, closes irrigation valve and has stopped the unnecessary waste of human resources thereby need not painstakingly keep at water meter other or time of pinching.
