The utility model has advantages below compared with prior art：
1st, the utility model changes water inlet flow section by flexible sheet deformation, when hydraulic pressure increases to certain value
When, flexible sheet starts to deform, and when hydraulic pressure continues to increase, flexible sheet deformation increases therewith causes flexible sheet and current limliting boss
The flow section of formation reduces and then plays a part of current stabilization, reliable operation.
2nd, flexible sheet is relied on when the design of lid anti-suck water shutoff circle can produce negative pressure in pipeline on the utility model
Pressure caused by elasticity and negative pressure shuts water flow circuits, is blocked it is possible to prevente effectively from negative pressure inhales mud.
3rd, it is general can effectively to reduce blocking by the circular saw runner being arranged in upper lid inside bottom surface for the utility model
Rate, while to ensure necessary waterpower damage, using outer ring runner design, necessary flow channel length can be protected, big stream so can be achieved
Road, the design of low discharge.
4th, the utility model is simple in construction, easy for installation, is just adapted to not by the flexible sheet for changing different size
Same hydraulic pressure, strong applicability.

Embodiment
As shown in Fig. 1 ~ 3, a kind of anti-down suction pipe above formula pressure compensation douche of anti-clogging, the douche includes being connected to one
The lower casing 1 and upper lid 3 and built-in flexible sheet 2 risen.
The one end of lower casing 1 is provided with cone-shape barbs delivery port 4, and center of inside is provided with apopore 14, current limliting boss 12, overflow launder
13, outer ring is provided with diaphragm mounting flange 18, coordinates Sealing Surface 19；Drainage water outlet is offered on the inner side cylinder of diaphragm mounting flange 18
Mouth 15；Coordinate and offer circular drainage water inlet 16 in Sealing Surface 19, the circular drainage water inlet 16 is with draining the phase of delivery port 15
Connection；Diaphragm mounting flange 18 is provided with flexible sheet 2；The case inside cylinder of lower casing 1 is in 90 ° of circle distributions provided with three
Installing locating slot 11；Upper one end of lid 3 is provided with cone-shape barbs water inlet 6, and center of inside is provided with anti-suck water shutoff circle 8, and outer ring is set
There is circular saw runner 20；The section start of circular saw runner 20 is provided with runner water inlet 10, and end is provided with flow field end water chamber
9；Circular saw runner 20 is with coordinating Sealing Surface 19 to fit；Three are provided with the outside of the lid of upper lid 3 in 90 ° of circle distributions to determine
Position boss 17, the positioning boss 17 match with installing locating slot 11.
Wherein：Flexible sheet 2 is disk made of silicon rubber.
The phase of cone-shape barbs water inlet 6 is divided into water high pressure chest 7 by the side that meets water of flexible sheet 2, and the land side of flexible sheet 2 will
The phase of cone-shape barbs delivery port 4 is divided into pressure compensation chamber 5.
During assembling, flexible sheet 2 is arranged on the diaphragm mounting flange 18 of lower casing 1 first, adjustment position makes on lid 3
Positioning boss 17 corresponded with the installing locating slot 11 on lower casing 1 after upper lid 3 be pressed into lower casing 1 welded again.Group
After welding equipment connects, the circular saw runner 20 in upper lid is brought into close contact with the cooperation Sealing Surface 19 on lower casing, forms single path
Closed flow.
During work, current are entered by the cone-shape barbs water inlet 6 on upper lid 3 meets water what side was separated by by flexible sheet 2
Intake after high pressure chest 7, then circular saw runner 20 is entered by runner water inlet 10, current are flowed through after circular saw runner 20 by flowing
Road outlet water at tail end chamber 9 enters circular drainage water inlet 16, is then entered by drainage delivery port 15 and is separated by by the land side of flexible sheet 2
In the pressure compensation chamber 5 formed, then by the surrounding of current limliting boss 12 and overflow launder 13 into apopore 14, finally by hangnail delivery port
4 outflow water droppers enter soil.
Pressure compensation principle：In the course of work, when hydraulic pressure increases, flexible sheet 2 meet water side water inlet high pressure chest 7 in pressure
Rise, the deformation of flexible sheet 2 is caused to increase, now flexible sheet 2 reduces with the flow section that current limliting boss 12 is formed, and then
Prevent the increase of the flow caused by the increase of hydraulic pressure；Conversely, when hydraulic pressure reduces, flexible sheet 2 meets water side water inlet
Pressure reduces in high pressure chest 7, causes the deformation of flexible sheet 2 to reduce, the excessively stream that now flexible sheet 2 is formed with current limliting boss 12
Section increases, and then prevents the reduction of the flow caused by the reduction of hydraulic pressure, so dynamic regulation, it is ensured that one
The stabilization of flow in the range of constant-pressure.When the moment of cutting off the water, when douche pipe laying produces negative pressure, flexible sheet 2 returns at itself
It is brought into close contact in the presence of elastic force and negative pressure with anti-suck water shutoff circle 8, prevents current from flowing back, plays anti-suck effect.
