Description

Drip irrigation drip-proof device

Technical Field

The invention relates to the technical field of flower irrigation, in particular to an anti-dripping device for drip irrigation.

Background

In recent years, the flower industry in China is gradually developed, the flower planting varieties are continuously increased, people pay attention to the construction of the ecological environment, the increasing demand of flowers is expanded, the rapid growth of the flower production and consumption is favorably promoted, the flowers have been developed into an industry and become an important component of the planting industry, and the irrigation mode of the flowers also starts to develop in a diversified way. Among them, the drip irrigation is one of the advanced irrigation methods, and the drip irrigation refers to irrigating crops in the form of drip irrigation such as drip irrigation or continuous fine water flow by using an irrigator. By adopting the drip irrigation, the consequence that the root system of the crops is rotten due to overlarge humidity after other irrigation modes are irrigated can be avoided, so that the drip irrigation is the best choice for irrigation of most greenhouse flowers.

In order to facilitate management and save space, the drip irrigation system is generally arranged above the flowers, and after the drip irrigation emitter is mounted upside down, direct water supply is convenient to irrigate the flowers. However, after the water pump is turned off, water drops still drop downwards, and the water drops strike the blades of the flowers and are easy to damage the flowers; the water for watering flowers is too much, so that the water cannot be fully absorbed, and the water resource is wasted; some drip irrigation systems are provided with drip-proof devices, and shake back and forth under the influence of air flow, so that normal work is influenced, and potential safety hazards exist.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, a drip-proof device for drip irrigation includes a main body 1, a socket joint 2 fixedly connected to the left end of the main body 1, a taper joint 3 fixedly connected to the right end of the main body 1, the socket joint 2 connected to a drip emitter, and the taper joint 3 connected to an irrigation pipe. The upper end middle part fixedly connected with montant 4 of antidrip device main part 1, the surface of montant 4 is provided with spring 5, the upper portion swing joint of montant 4 has sealing rubber 6, sealing rubber 6 passes through sliding connection between spring 5 and the montant 4, receives the water pressure of certain degree on sealing rubber 6's upper portion, can make sealing rubber 6 downstream, and hydraulic reduction or disappearance, and starting position will be got back to sealing rubber 6. The upper part of the drip-proof device main body 1 is in threaded connection with a drip-proof cover 7, the middle part of the lower end of the drip-proof cover 7 is provided with an annular notch 8, the sealing rubber 6 is right below the annular notch 8, the sealing rubber 6 is in close contact with the lower surface of the annular notch 8, the combination and the separation of the sealing rubber 6 and the annular notch 8 are directly associated with the pressure of a water pump, after a water source is connected, when the water pressure reaches the working pressure, the sealing rubber 6 is separated from the annular notch 8, and water flows to a drip-proof dripper; when the water pressure is lower than the working pressure after the water source is closed, the sealing rubber 6 is combined with the annular notch 8, and water cannot flow to the drip irrigation emitter. Prevent that the upper portion joint of dripping lid 7 has wind cap 9, and the outer wall of wind cap 9 is provided with through-hole 10, and wind cap 9 is connected with anti-drip lid 7 through the mode of rotatory joint, and the outer wall of wind cap 9 is provided with equidistant, the unanimous through-hole 10 of size all around, and under the condition that drip irrigation system received the air current, the air current flowed away through a plurality of through-holes 10, can reduce the impact resistance to anti-drip device body 1, has avoided hanging upside down to drip irrigation the water dropper and has taken place to rock under the air current effect. The upper portion of sealing rubber 6 is provided with protruding soft bag 11, protruding soft bag 11 and sealing rubber 6 structure as an organic whole, and bulk strength is high, long service life, protruding

soft bag

11 and 8 in close contact with of annular notch make sealed effect better, are favorable to preventing the phenomenon of storing up the rivers water clock in the pipeline.

When the pipeline starts to supply water, water flow enters the anti-drip device main body 1, when the working water pressure is reached, the pressure of the water pressure acts on the sealing rubber 6, the spring 5 is compressed, the sealing rubber 6 is separated from the annular notch 8, so that a channel of the water inlet and the water outlet is communicated, and at the moment, the anti-drip device is in an open state; when the pipeline stops supplying water, behind the water pressure in the pipeline is less than operating water pressure, because spring 5 has taken place deformation under hydraulic effect, spring 5 can make the upwards motion of sealing rubber 6, resume to the original position of sealing rubber 6, at this moment, just sealing rubber 6 and annular notch 8 recombine, rivers that store up in the pipeline can not have sufficient pressure and arouse the removal of sealing rubber 6, the passageway disconnection that the water inlet is connected with the delivery port, consequently, prevented to store up the problem of the rivers drippage in the pipeline. When the water is supplied next time, the channel is opened again after the working water pressure is reached, and the whole process is repeated.

In conclusion, the drip-proof device can effectively control the inversely-hung drip irrigation drippers to be close to and attached to the annular notches 8 on the drip-proof cover 7 gradually along with the reduction of water pressure under the action of the elasticity of the springs 5 under the condition that a pipeline water source is closed, so that the flow direction of residual water to the drip irrigation drippers is blocked, the drip irrigation drippers are ensured not to drip water, and flowers are effectively protected. Drip irrigation system adopts the antidrip device, and after the water source was closed, can prevent that remaining water from constantly driping out in the pipeline, avoids unnecessary water shunt loss, water economy resource. This antidrip device has windproof effect, and under the condition that drip irrigation system received the air current, the air current flowed away through a plurality of through-holes 10, can reduce the impact resistance to antidrip device body 1, has avoided hanging upside down and has driped irrigation the water dropper and take place to rock under the air current effect, plays basic stabilizing effect.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
