Abstract

The utility model relates to a water controlling water valve, which is composed of a water inlet chamber, a water outlet chamber, a control chamber, a rubber piece and a one-way channel. The utility model adjusts the water pressure of the control chamber through the one-way channel while completes the on-off of the water controlling water valve through the on-off of the rubber piece; the water pressure of the control chamber reversely controls the on-off of the rubber piece, in the process of circulation and reciprocation, the purpose of spraying without intermission is achieved. The utility model can be used for sprinkling irrigation and fog fertilization. The water controlling water valve has the effects of power saving and water saving.

Description

Water-controlled hydrovalve

The utility model relates to a kind of plant rainer.

When most plant cuttage breeding or seedling culture, need a kind of intermittent spraying equipment, improve air humidity.Adopt the keying of Electronic Control water valve at present.As " timing automatic the water flowers control device " of notification number for " CN2217872Y ", this device need have power supply, electronic original part, and to programme cost height, inconvenience.

The utility model purpose provides a kind of power supply that do not need, and utilizes hydraulic pressure to control the device that water valve opens and closes, and realization automatic irrigation, mist are educated dual-purpose.

Technical characterictic of the present utility model is: device is made up of intake antrum, water chamber, control chamber, rubber tissue, half-duplex channel.Water chamber is positioned in the middle of the intake antrum, and both are positioned at the same side of rubber tissue, has spring that rubber tissue is pressed on the water chamber; The opposite side of rubber tissue is a control chamber, and control chamber has half-duplex channel to communicate with water chamber.Do not have at control chamber under the situation of hydraulic pressure, the hydraulic pressure of intake antrum backs down rubber tissue, and intake antrum is communicated with water chamber, and water valve is in opening.When the water chamber water-filling had had hydraulic pressure, hydraulic pressure arrived control chamber by half-duplex channel, and control chamber is full of with the same hydraulic pressure of intake antrum, and spring is pressed on the water chamber rubber tissue, and water valve cuts out.Passage between control chamber and the water chamber is a half-duplex channel, guarantees that hydraulic pressure can keep a period of time in control chamber.When the hydraulic pressure of control chamber unloads when being pressed onto to a certain degree naturally, water valve repeats breakdown action again, makes like this that water valve is constantly opened, closed circulation.

The utility model with conventional device relatively owing to cancelled power supply, electronic component, is directly controlled the keying of water valve by hydraulic pressure, both easy to use, reduces expenses again.

Provide symbol figure explanation and embodiment below

As scheming: the A chamber is an intake antrum, and the B chamber is a water chamber, and the C chamber is a control chamber.Water chamber B is made in the centre of intake antrum A, and rubber tissue 4 outer gardens cover intake antrum A, are tightened by shell, and interior garden covers water chamber B, is pressed on the accent by spring 2.The pressure of control chamber size and 2 pairs of rubber tissues 4 of spring is regulated in gong nail 1 and piston 6 combinations, is used for regulating the length of water valve closing time, the control injection flow rate.Rubber tissue 4 central authorities have a hole, and water chamber B is communicated with control chamber C, load onto check-valves on the hole, make half-duplex channel 3, make hydraulic pressure from water chamber B to control chamber C unidirectional delivery, keep a period of time hydraulic pressure to realize control chamber C.Shower nozzle 5 can directly be made on the water chamber B, but also pipeline picks out.

The utility model job step is as follows: the first step, and when control chamber C did not have hydraulic pressure, the hydraulic pressure of intake antrum A backed down rubber tissue 4, and intake antrum A communicates with water chamber B, and water valve is in opening, shower nozzle 5 water sprays.In second step, the water chamber water-filling has had hydraulic pressure, and hydraulic pressure passes among the control chamber C by half-duplex channel 3, makes the C chamber equate that with A chamber hydraulic pressure spring 2 is pressed on rubber tissue 4 on the accent of water chamber B, and the A chamber is ended with B chamber current, and water valve cuts out.In the 3rd step, because the effect of half-duplex channel 3, the water of control chamber C can not be back among the water chamber B, so water pressure energy keeps a period of time in control chamber C.In the 4th step, hydraulic pressure nature release among the control chamber C when surpassing the pressure of spring 2 with the pressure differential of intake antrum A, repeats first step action, and like this, as long as among the intake antrum A hydraulic pressure is arranged, action will be gone down in infinite circulation.It will be such that the utility model works together: shower nozzle 5 water smokes one dodge, and close, and wait for a moment and are sudden strains of a muscle, constantly repeat up to turn-offing the water source, and water is saved very much, do not waste a water guaranteeing to improve under the prerequisite of air humidity at once.Adjust gong nail 1, make the pressure of spring 2 very little, shower nozzle is very little 5 break times, can realize the operation of spraying.
