Description
Technical Field
The scheme belongs to the technical field of water-saving irrigation, and particularly relates to an anti-siphon pressure compensation type purple high-resistance drip irrigation pipe.
Background
The buried drip irrigation is a novel drip irrigation technology which is widely popularized in the United states, australia, israel and other countries in recent years, namely a drip irrigation mode that drip irrigation capillary tubes are paved below a cultivation layer to irrigate water and fertilizer needed by crops to the roots of the crops. The irrigation technology can directly supply water, fertilizer, gas and the like to the root systems of crops, so that the irrigation technology has remarkable water-saving, yield-promoting and conditioning effects. Meanwhile, the buried drip irrigation technology has the advantages that the drip irrigation device (drip irrigation pipe or drip irrigation tape) is prevented from being corroded by ultraviolet rays and damaged by external force, the service time is prolonged, the automation degree is high, labor is saved, water does not exist on the ground surface, weeds and plant diseases and insect pests are effectively controlled, and the like.
However, the buried drip irrigation pipe has the biggest problem of being easily clogged. The main reasons for its blockage are: physical and biological plugs. The physical blockage is mainly in the initial stage of water filling, and the positive pressure outside the water outlet is smaller and the outflow rate of the water outlet is larger because the soil around the water outlet has lower moisture and more air. Along with the extension of the irrigation time, the water content of the soil around the water outlet is increased, and the water quantity is not diffused into the soil until reaching the effect of the diffusion capacity of the soil and the exhaust process in soil, namely, a saturation region is formed around the water outlet, so that the positive pressure outside the water outlet is increased, and the outflow of the irrigator is possibly reduced under the action of the positive pressure. When the water filling is stopped, a saturated slurry area is formed in a larger range around the water outlet, air is basically discharged, and at the moment, if a water source is suddenly closed, the air cannot enter the drip irrigation pipe immediately, so that negative pressure is formed in the drip irrigation pipe instantly, the external pressure of the water outlet of the drip head is larger than the internal pressure, and therefore sediment around the water outlet of the drip head easily enters the drip head under the action of the pressure difference, and the siphon of the drip head is blocked. Biological blockage is mainly caused by uneven irrigation, and weeds or plant roots grow towards the water outlet, so that blockage is formed.
Accordingly, there is a great need for a device that reduces clogging of drip irrigation tubing to increase the useful life of the drip irrigation tubing.
Disclosure of Invention
The scheme provides an anti-siphon pressure compensation type purple high-resistance drip irrigation pipe, so as to reduce the blockage of the drip irrigation pipe.
In order to achieve the above purpose, this scheme provides an anti-siphon pressure compensation formula purple high resistance drip irrigation pipe, including the drip irrigation pipe body, the drip irrigation pipe body from the top down is valve chamber, medicament chamber and drip irrigation chamber in proper order, be equipped with the first valve that is used for weeding in the valve chamber and be used for drip irrigation the second valve, first valve and medicament chamber intercommunication, second valve and drip irrigation the chamber intercommunication, and first valve and second valve are the check valve, the drip irrigation pipe body of first valve department is the non-straight line with the drip irrigation pipe body of other parts, and the medicament chamber is the elastic surface with the face of drip irrigation the chamber contact.
The principle and beneficial effect of this scheme lie in:
1. according to the scheme, the medicament cavity and the drip irrigation cavity are arranged, so that drip irrigation and medicine dripping can be performed on soil according to needs, and the functions are more. Meanwhile, the arrangement of the medicament cavity can kill weeds, effectively prevent the root systems of the weeds from blocking the water outlet, and effectively reduce the situation of biological blocking.
2. The first valve and the second valve are arranged as the one-way valves, so that siphon effect caused by negative pressure can be effectively reduced, sediment entering the drip irrigation pipe is reduced, and physical blockage is effectively reduced.
3. The drip irrigation pipe body at the first valve and the drip irrigation pipe body at other parts are nonlinear, and the surface of the medicament cavity, which is contacted with the drip irrigation cavity, is an elastic surface. In this scheme, the non-straight line has a certain curvature. Thus, there is a high tendency for "water hammer". The medicine in the medicine cavity can be conveniently extruded out of the first valve by utilizing the water hammer phenomenon, so that drip irrigation of the medicine is completed. The device has the advantages that in long-distance pipelines, the water hammer phenomenon is very difficult to avoid, and the bending degree of the drip irrigation pipe is artificially controlled, so that the water hammer phenomenon can be manufactured in places where the drip irrigation pipe is needed again artificially, the water hammer phenomenon of other departments is further reduced to a certain extent, and the service life of the whole device is prolonged as long as the artificial bending part is specially reinforced. The drip irrigation device has the advantages that the water hammer can be well formed by only closing the water inlet valve of the drip irrigation pipe after drip irrigation is finished every time, automatic medicine dripping is realized, the operation is simple, and additional operation is not needed.
Further, the first valve and the second valve are identical in structure. Thus, the same batch of parts can be shared, and the cost is lower.
Further, the first valve comprises a valve body, a first filter screen, a second filter screen, a first spring and an anti-blocking unit, wherein the first filter screen is arranged at a water inlet of the valve body, the second filter screen is fixed in the valve body, a sealing ball matched with the second filter screen is also arranged in the valve body, and the first spring is arranged between the sealing ball and the second filter screen; the anti-blocking unit comprises an anti-blocking ball and a second spring, one end of the second spring is fixed on the second filter screen, the anti-blocking ball is fixed at the free end of the second spring, and the anti-blocking unit is obliquely arranged.
The arrangement of the filter screen can form multi-effect protection, and effectively reduce blockage. Meanwhile, the anti-blocking unit is obliquely arranged, so that the anti-blocking unit can store water under the impact force of water when drip irrigation is carried out, and can swing back and forth under the action of the second spring after drip irrigation is stopped once the drip irrigation is stopped. Therefore, the anti-blocking ball can strike the water outlet of the valve to generate vibration, and the phenomenon that dirt is attached to the water outlet of the valve to form blocking is avoided.
Further, the length of the anti-blocking unit is matched with the distance from the second filter screen to the water outlet of the valve body, and therefore the anti-blocking ball can also impact the filter cloth, and blocking outside the filter cloth is reduced. The matching means that the length of the anti-blocking unit is slightly longer than the distance from the second filter screen to the water outlet of the valve body.
Further, the outer surface of the drip irrigation pipe body is provided with filter cloth. The filter cloth can effectively reduce the blocking condition.
Further, the filter cloth is purple filter cloth. The purple filter cloth is convenient for finding out the drip irrigation pipe on one hand, and can effectively absorb ultraviolet rays on the other hand, so that the aging of the drip irrigation pipe is reduced.
Further, the drip irrigation pipe at the first valve is a gooseneck pipe, and the rest drip irrigation pipes are polyethylene drip irrigation pipes. The setting of gooseneck can conveniently control the crookedness of drip irrigation pipe, and the adjustability is higher. Meanwhile, the gooseneck is also higher in strength and not easy to damage.

In a specific matching scheme, as shown in the figure, the channel of the valve body 401 is generally configured in an inverted conical shape or a shape with a large upper part and a small lower part, and the diameter of the sealing ball 403 is larger than the minimum value of the channel of the valve body 401.
The anti-blocking unit comprises an anti-blocking ball 407 and a second spring 406, one end of the second spring 406 is fixed on the second filter screen 405, the anti-blocking ball 407 is fixed at the free end of the second spring 406, and the anti-blocking unit is integrally inclined leftwards by 20 degrees. The length of the anti-blocking unit is slightly longer than the distance from the second filter screen 405 to the water outlet of the valve body 401, and the anti-blocking unit can be adjusted according to practical situations, but is generally not more than 10mm. Thus, the anti-blocking ball 407 also impacts the filter cloth, thereby reducing clogging outside the filter cloth.
In addition, the outer surface of the drip irrigation pipe body 10 is provided with a filter cloth, the filter cloth is purple, the drip irrigation pipe is conveniently found by the purple filter cloth, and the drip irrigation pipe can effectively absorb ultraviolet rays and reduce aging of the drip irrigation pipe.
Compared with the traditional drip irrigation pipe, the drip irrigation pipe has the advantages that the medicament cavity 20 and the drip irrigation cavity are arranged, the drip irrigation and the medicine dripping can be respectively carried out on the soil according to the needs, and the functions are more. Meanwhile, the arrangement of the medicament cavity 20 can kill weeds, effectively prevent the root systems of the weeds from blocking the water outlet, and effectively reduce the situation of biological blocking. Meanwhile, the first valve and the second valve are arranged as the one-way valve 40, so that siphon effect caused by negative pressure can be effectively reduced, sediment entering the drip irrigation pipe is reduced, and physical blockage is effectively reduced. In addition, the automatic medicine dropping can be realized by utilizing the water hammer phenomenon, and the operation is convenient. Finally, the unique one-way valve 40 structure can play a good anti-blocking role.
The foregoing is merely exemplary embodiments of the present application, and specific structures and features that are well known in the art are not described in detail herein. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present application, and these should also be considered as the scope of the present application, which does not affect the effect of the implementation of the present application and the utility of the patent.
