The highly-blocking-resistant back-sucking prevention pressure compensation flow stabilizer is simple in structure and convenient to mount, the elastic membrane and the upper cover water sealing ring are matched, so that output flow of an irrigation emitter is small, output flow is stable, irrigation evenness is high, blocking caused by negative pressure mud suction is prevented, the service life of an irrigation system is prolonged, and irrigation cost is saved.

Description

The stifled anti-suck pressure compensation flow straightener of a kind of high resistance
Technical field
The utility model relates to tubule in water-saving irrigation device and goes out to flow the stifled anti-suck pressure compensation flow straightener of a kind of high resistance of irrigation system irrigator.
Background technology
Tubelet effluent irrigation system is China applying in high-efficiency water-saving micro irrigation technology, for strengthening irrigator anti-blocking, foundes a kind of high anti-blocking micro irrigation technology.At present, the flow straightener flow of tubelet effluent irrigation system irrigator is little, its runner flow section size is little, anti-blocking is poor, and when flow straightener be embedded in underground or while pouring water hollow billet submerge in muddy water, in the time cutting off the water, be easy to produce negative pressure because head falls after rise in pipeline, be now easy to cause flow straightener negative pressure to inhale mud and stop up, when serious, cause whole irrigation system collapse.
Summary of the invention
The technical problems to be solved in the utility model is: solved that existing tubelet effluent irrigation system irrigator flow straightener anti-blocking is poor, negative pressure inhales mud blockage problem.Provide a kind of overcome rill and the high anti-blocking of large runner between the flow straightener of contradiction, it can keep irrigator outflow little, goes out stream stable, uniformity of irrigation water appilcation is high, can avoid again negative pressure to inhale mud and stop up, and extends irrigation system service life, saves irrigation cost.
Summary of the invention of the present utility model is: it is to be made up of upper cover, flexible sheet, lower casing three parts; Described upper cover one end is provided with cone-shape barbs water inlet, and inside is provided with the water shutoff circle of annular projection; Described lower casing one end is provided with cone-shape barbs delivery port, and inside is provided with flexible sheet mounting flange, current limliting boss, and exterior annular cylinder is provided with the wide runner of zigzag; Flexible sheet one side offers sawtooth runner water inlet, and diaphragm opposite side offers sawtooth runner delivery port, between sawtooth runner water inlet and sawtooth runner delivery port, is provided with gear lattice.
Described flexible sheet can according to circumstances need with different size, to adapt to different hydraulic pressure.
The distortion of the utility model dependence flexible sheet carrys out regulating flow-stabilizing device flow and improves its uniformity of pouring water, and lower casing anchor ring is provided with the wide runner of zigzag simultaneously, has guaranteed the performance of anti-blockage that flow straightener is good when realizing current decompression energy dissipating.The design of upper cover water shutoff circle relies on flexible sheet elasticity and negative pressure to produce pressure can produce negative pressure in pipeline time is shut current loop, and the cooperation of flexible sheet and water shutoff circle can anti-suck, avoids the negative pressure of flow straightener to inhale mud and stops up.
The utility model has the advantages that:
1, the utility model is simple in structure, easy for installation.
2. the utility model changes water inlet flow section by flexible sheet deformation, in the time that hydraulic pressure increases to certain value, flexible sheet starts distortion, when hydraulic pressure continues to increase, the flexible sheet distortion flow section that increasing causes flexible sheet and current limliting boss to form thereupon reduces and then plays the effect of current stabilization, reliable operation.
3. the utility model, by the coordinating of flexible sheet and upper cover water shutoff circle, can effectively be avoided negative pressure to inhale mud and stop up.
4. the utility model, by being arranged on the wide runner of sawtooth on lower casing anchor ring, has very large flow section when effectively energy dissipating is reduced pressure, improves flow straightener performance of anti-blockage.
5. the utility model can just can adapt to different hydraulic pressure by the flexible sheet of changing different size, and applicability is strong.

Embodiment
A kind of high resistance of the present utility model is blocked up anti-suck pressure compensation flow straightener, and it is by upper cover (1), flexible sheet (2), lower casing (3); Described upper cover (1) one end is provided with cone-shape barbs water inlet (4), and inside is provided with the water shutoff circle (5) of annular projection; Described lower casing one end is provided with cone-shape barbs delivery port (6), inside is provided with diaphragm mounting flange (7) and the current limliting boss (9) to its supporting role of flexible sheet (2), exterior annular cylinder is provided with the wide runner of zigzag (8) for current energy dissipating, flexible sheet (2) one sides offer sawtooth runner water inlet (10), diaphragm opposite side offers sawtooth runner delivery port (11), between sawtooth runner water inlet (10) and delivery port (11), be provided with gear lattice (12), guarantee the current whole runner of can flowing through.
The utility model changes water inlet flow section by the deformation of flexible sheet (2), current enter flow straightener by cone-shape barbs water inlet (4), enter the wide runner of zigzag (8) by the runner water inlet (10) that is opened in diaphragm one side, the current of the wide runner of the zigzag of flowing through (8) enter diaphragm opposite side by the runner delivery port (11) that is opened in diaphragm opposite side, are finally flowed out by cone-shape barbs delivery port (6) by current limliting boss (9).In the course of work, in the time that hydraulic pressure increases to certain value, flexible sheet (2) starts distortion, and when hydraulic pressure continues to increase, flexible sheet (2) the distortion flow section that increasing causes flexible sheet and current limliting boss to form thereupon reduces and then play the effect of current stabilization.When cutting off the water the moment, flow straightener pipe laying produces when negative pressure, flexible sheet (2) under the effect of self screen resilience and negative pressure with anti-suck water shutoff circle (5) laminating, stop current to reflux, play anti-suck effect.
