The utility model discloses the advantage can prevent effectively that high -pressure water pressure water -logging pressure is too high and burst.
Description
Technical field
The utility model relates to a kind of drip irrigation equipment, specifically refers to a kind of constant voltage injecting type drip irrigation emitter.
Background technology
Drip irrigation emitter is mainly used in carrying out water savingization to field-crop and irrigates, and dropper mode has two advantages important greatly:
The first, effectively utilizing of injection water is high, and under condition of drip irrigation, the moistening part soil surface of water, effectively can reduce the invalid evaporation of soil moisture;
The second, due to the soil of root near drip irrigation only moistening crops, the growth of weeds therefore can be prevented.
3rd, drip irrigation does not produce surface runoff, and easily grasp executes water depth, very water-saving accurately.
At present, traditional drip irrigation emitter relatively simple for structure, has generally comprised cistern, water pump, high-pressure water tank and drip irrigation nozzle, and to be added by the water in cistern by water pump and be sent in high-pressure water tank, then water under high pressure sprays from drip irrigation nozzle.Once when there is drip irrigation spray nozzle clogging in this structure, the hydraulic pressure in high-pressure water tank can continue to raise, thus causes high-pressure water tank to burst, and is therefore necessary to improve.
Utility model content
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of reasonable in design, the constant voltage injecting type drip irrigation emitter that safety is good.
For achieving the above object, the technical solution of the utility model includes cistern, water pump, high-pressure water tank and drip irrigation nozzle, drip irrigation nozzle is arranged on the delivery port of high-pressure water tank, also include water storage box, the first feed pipe is connected with between described cistern and water storage box, described water pump is arranged on this first feed pipe, the second feed pipe is connected with between described water storage box and high-pressure water tank, this second feed pipe is provided with the first one-way pressure valve from water storage box to the one-way flow of high-pressure water tank direction, the first return pipe is also provided with between described high-pressure water tank and water storage box, this first return pipe is provided with the second one-way pressure valve.
Further setting is that the structure of the first described one-way pressure valve and the second one-way pressure valve includes uniaxial pressure valve body, the steel ball be arranged in uniaxial pressure valve body, compression spring and regulate the look nut of compression spring rate of tension, import valve seat is provided with in uniaxial pressure valve body, steel ball and import valve base sealing adaptation, the two ends of compression spring abut with steel ball and look nut phase elasticity respectively.
Further setting is that described the first return pipe is provided with the check valve from high-pressure water tank to water storage box one-way flow near one end of water storage box.
Further setting is that described the first feed pipe is provided with filter.
Further setting is connected with the second return pipe between described water storage box and cistern, and this second return pipe is provided with the 3rd one-way pressure valve from water storage box and cistern one-way flow near one end of water storage box.
Operation principle of the present utility model and advantage are: this setting, and the effect of cistern receives rainwater or manually executes water as a water source.The effect of filter is the impurity in filtered water reservoir, allows clean water enter into drip irrigation nozzle.Water pump be then energising after ceaselessly by the water in pond, be pumped in water storage box.After the water of water storage box reaches certain pressure, back down the first one-way pressure valve, water just enters into high-pressure water tank, because water inlet is with certain pressure, so can be ejected by drip irrigation nozzle.When the continual increase of water inlet, and the amount that drip irrigation nozzle sprays is subject to the impact of sectional area, therefore the pressure of high-pressure water tank inner fluid continues to raise, when the pressure durations of water in high-pressure water tank is raised to high a certain value, then back down the second one-way pressure valve, water enters into water storage box from the first return pipe.Simultaneously, under second one-way pressure valve open mode, because in high-pressure water tank, pressure is larger, so the closedown on the first one-way pressure valve, thus make do not have water to enter in high-pressure water tank again, and the water in high-pressure water tank is after backing down the second one-way pressure valve, is flowed away by the first return pipe, so the pressure in high-pressure water tank also reduces gradually, the hydraulic pressure in water storage box is raising gradually.After hydraulic pressure in high-pressure water tank reduces, the second one-way pressure valve is closed again, and meanwhile, in high-pressure water tank, pressure reduces, and also make hydraulic pressure in water storage box be greater than hydraulic pressure in high-pressure water tank, the first one-way pressure valve reopens, and water adds to again in high-pressure water tank.In order to increase the safety of hydraulic pressure in water storage box, then at water storage box top safety the 3rd one-way pressure valve, when the value that pressure in water storage box is larger more than, then open the 3rd one-way pressure valve, allow the water in water storage box enter into cistern, again participate in circulation.
The utility model, by above-mentioned setting, can effectively prevent hydraulic pressure in high water pressure too high and the problem of explosion.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
