Technical field
The utility model belongs to irrigation equipment field, more particularly to a kind of flushing valve of droping irrigating pipe end.
Background technique
Trickle irrigation (drip irrigation) is aperture or the drop passed through water using droping irrigating pipe on diameter about 10mm hollow billet 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 have it is very much, such as: impurity in water, not Blocking caused by fertilizer is dissolved, blocks caused by microbial growth, is 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 will lead to salinity deposition stifled On the other hand the problems such as plug, microorganism clogging, can also freeze in winter, damage equipment.
Utility model content
To solve the above problems, the utility model provides a kind of flushing valve of droping irrigating pipe end, opened in drip irrigation system When droping irrigating pipe can be rinsed automatically, the water in pipeline can also be drained after irrigation automatically.
The utility model is achieved by the following technical solution:
A kind of flushing valve of droping irrigating pipe end, including shell, the housing central section are fixed with elastic sealing strip, elastic packing Enclosure interior space is divided into the first cavity and the second cavity by piece;First cavity is equipped with inlet opening and apopore, institute It states inlet opening and is connected with water inlet pipe, water inlet pipe is connect with droping irrigating pipe;Second cavity is connected to by water channel with water inlet pipe;Institute Elastic deformation can be occurred under the effect of the pressure of the second cavity by stating elastic sealing strip, 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 between bottom case and upper cover by groove;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 fastens upper cover and bottom case closely to be integrated, and presses By being threadedly engaged fixation 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 and water inlet pipe connects Logical, the other end passes through elastic sealing strip and enters the second cavity.
Further to improve, the bottom case and upper cover are respectively equipped with mutually matched groove and convex block, are fixed upper cover In designated position.
Further to improve, the bottom case bottom and water inlet pipe are integrally formed, and reinforcement is additionally provided between bottom case and water inlet pipe Muscle.

Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, and make the upper of the utility model It states feature, purpose and advantage and is more clear understandable, explanation is further explained to the utility model now in conjunction with embodiment, should be referred to Out, all embodiments listed here are merely illustrative, are not meant to be defined the scope of the utility model.
Embodiment 1:
A kind of flushing valve of droping irrigating pipe end, including shell, the housing central section are fixed with elastic sealing strip 3, the shell Body includes bottom case 4, upper cover 2 and pressure ring 1, and the edge of the bottom case 4 and upper cover 2 is all provided with fluted, the edge of elastic sealing strip 3 It is fixed between bottom case 4 and upper cover 2 by groove;The first cavity 6, elastic sealing strip are formed between elastic sealing strip 3 and bottom case 4 The second cavity 7 is formed between 3 and upper cover 2;The pressure ring 1 makes upper cover 2 and bottom case 4, and closely fastening is integrated, pressure ring 1 and bottom case 4 Between by being threadedly engaged fixation.
First cavity 6 is equipped with inlet opening 41 and apopore 42, and the inlet opening 41 is connected with water inlet pipe 5, bottom case 4 Bottom and water inlet pipe 5 are integrally formed, and reinforcing rib is additionally provided between bottom case 4 and water inlet pipe 5, and water inlet pipe 5 passes through screw thread and drip irrigation pipe Road connection.Apopore 42 has multiple, the circular setting of inlet opening 41.
Second cavity 7 is connected to by water channel 8 with water inlet pipe 5, and the water channel 8 is the water channel of labyrinth shape meander wire, This shape makes water flow on the corner form vortex, and the foreign matters such as silt can be prevented with water flowing blocking water channel 8.Labyrinth shape water channel by Following part is constituted: the groove at 4 edge of bottom case is equipped with labyrinth-like protrusion, and the labyrinth-like protrusion 43 is matched with elastic sealing strip 3 The water channel 8 for forming the labyrinth-like around 4 edge sealing in one week of bottom case is closed, 8 one end of water channel passes through bottom case 4 and is connected to water inlet pipe 5, separately One end passes through elastic sealing strip 3 and enters the second cavity 7.Upper cover 2 has the recess of a cooperation water channel 8, bottom in 8 outlet port of water channel Shell 4 and upper cover 2 are respectively equipped with mutually matched groove and convex block, and upper cover 2 is made to be fixed on designated position.The inlet opening 41 is straight Diameter is 4-7 times of 8 diameter of water channel, to guarantee having enough washing times.
Elastic sealing strip 3 is the critical component that auto-flushing, draining are realized in end flushing valve.As shown in Figure 4,5, elasticity is close Mounting 3 is one piece of sheet rubber, and elastic sealing strip 3 includes centrally located closure part 33 and the fixed part 31 positioned at outer, is blocked Part between portion 33 and fixed part 31 is deformations 32, and inlet opening 41 can be completely covered in the closure part 33.The deformations 32 be accordion, and when elastic sealing strip 3 is pressurized on one side, closure part 33 is released in fold expansion;When not by pressure, fold is in bullet Power effect is lower to restore to the original state.The structure of accordion can effectively enhance the elasticity of elastic sealing strip 3, improve 3 sound of elastic sealing strip Answer the sensitivity of variation in water pressure.The hole 34 of cooperation water channel 8 is additionally provided on elastic sealing strip 3.
