Description
Technical field
The invention belongs to irrigation equipment fields, more particularly to a kind of flushing valve of droping irrigating pipe end.
Background technology
Trickle irrigation（drip irrigation）It is that water is passed through into aperture on diameter about 10mm hollow billets or drop using droping irrigating pipe
Head is sent to crop root and carries out localized irrigation.It is a kind of most effective Water Saving Irrigation Mode of current drought and water-scarce area, water
Utilization rate is up to 95%.Trickle irrigation relatively sprinkling irrigation has higher water-saving and yield-increasing effect, while can improve one times of fertilizer efficiency in conjunction with fertilising
More than.It is applicable to fruit tree, vegetables, industrial crops and greenhouse to irrigate, can also be used for crop field in the place of drought and water shortage
Crop irrigation.
Trickle irrigation maximum shortcoming is easily to block.The reason of drip irrigation system blocks has very much, such as:Impurity in water, not
It dissolves and is blocked caused by fertilizer, blocked caused by microbial growth, blocked up caused by the calcium and magnesium molysite or other electrodeposition substances in water
Plug etc..These problems generally can be solved and be prevented by way of rinsing droping irrigating pipe, however be rinsed at present primary
The work of droping irrigating pipe is complex, is difficult to carry out in the case where trickle irrigation area is big.
It can water in being managed after another problem of trickle irrigation is irrigated at present.On the one hand water can cause salinity deposition stifled
On the other hand the problems such as plug, microorganism clogging, can also freeze in winter, damage equipment.
Invention content
To solve the above problems, the present invention provides a kind of flushing valve of droping irrigating pipe end, it can when drip irrigation system is opened
The water in pipeline can also be drained automatically to be rinsed automatically to droping irrigating pipe, after irrigation.
The present invention is achieved through the following technical solutions：
A kind of flushing valve of droping irrigating pipe end, including shell, the housing central section are fixed with elastic sealing strip, and elastic sealing strip will
Enclosure interior space is divided into the first cavity and the second cavity；First cavity be equipped with inlet opening and apopore, it is described into
Water hole is connected with water inlet pipe, and water inlet pipe is connect with droping irrigating pipe；Second cavity is connected to by water channel with water inlet pipe；The bullet
Property diaphragm seal elastic deformation can occur under the effect of the pressure of the second cavity, and block inlet opening completely.
Further to improve, the elastic sealing strip is one piece of sheet rubber, and elastic sealing strip includes centrally located closure
Portion and fixed part positioned at outer, the part between closure part and fixed part are deformations, the closure part can be completely covered into
Water hole.
Further to improve, the deformations are accordion, and when elastic sealing strip one side is pressurized, fold expansion is released
Closure part；When not by pressure, fold restores to the original state under the effect of elasticity.
Further to improve, the shell includes bottom case, upper cover and pressure ring, and the edge of the bottom case and upper cover is equipped with
The edge of groove, elastic sealing strip is fixed on by groove between bottom case and upper cover；Is formed between elastic sealing strip and bottom case
One cavity forms the second cavity between elastic sealing strip and upper cover；The pressure ring makes upper cover and bottom case, and closely fastening is integrated, and is pressed
It is fixed by screw-thread fit between ring and bottom case.
Further to improve, the groove at the bottom case edge is equipped with labyrinth-like protrusion, the labyrinth-like protrusion and elasticity
Diaphragm seal cooperatively forms the water channel of the labyrinth-like around the sealing in one week of bottom case edge, and water channel one end passes through bottom case to connect with water inlet pipe
Logical, the other end passes through elastic sealing strip to enter the second cavity.
Further to improve, the bottom case and upper cover are respectively equipped with mutually matched groove and convex block, upper cover are made to be fixed
In designated position.
Further to improve, the bottom case bottom is integrally formed with water inlet pipe, and reinforcement is additionally provided between bottom case and water inlet pipe
Muscle.
It is further to improve, 4-7 times of a diameter of water channel diameter in inlet opening.
Further to improve, the bottom case, water inlet pipe, upper cover and pressure ring are all adopted made of plastic.
Compared with prior art, the present invention has the following advantages：
The droping irrigating pipe end flushing valve of the present invention is when drip irrigation system is just opened, since elastic sealing strip pressure is smaller,
Water in droping irrigating pipe can be discharged from water outlet again after water inlet inflow, and flow can play the role of rinsing droping irrigating pipe.Bullet
Property diaphragm seal constantly increases with the pressure being subject to, and deformation quantity gradually increases, and finally shuts water inlet, and droping irrigating pipe starts at this time
Normal work.Irrigation terminates, and after drip irrigation system is closed, since hydraulic pressure continuously decreases in droping irrigating pipe, elastic sealing strip resets, drop
The water for filling extra in pipeline can be discharged from water outlet again after water inlet inflow.The present invention fully relies on drip irrigation system switch
When hydraulic pressure work, without in addition addition control system, fully automatically carry out pipe flushing and water discharge.The present invention can have
Effect ground prevents and solves the problems, such as that drip irrigation system is susceptible to plugging, is also possible to prevent freeze injury, can greatly enhance drip irrigation system
Stability reduces maintenance cost.
The structure of elastic sealing strip can sensitively respond variation in water pressure in the present invention, can reach certain time in flushing
After block water inlet.It is of the invention to irrigate the when of starting each and droping irrigating pipe is rinsed automatically through experiment, when flushing
Between be 15-20 second, flushing dose is 4-6 liters, and flushing effect is good.
