Description
Technical field
The utility model relates to the accessory of a kind of farmland low pressure pipe irrigation system, is specifically related to a kind of farmland low-pressure delivery pipe spiral cover antiflushing type quota intake, belongs to farmland piping transportation water irrigation field of engineering technology.
Background technology
The intake of low pressure pipe irrigation system is the critical facility from pipeline to farmland water distribution, intake place flow shape directly has influence on the stability of water intake facilities and the degradation degree to agricultural land soil, even can have influence on applying of advanced irrigation technique.Along with farmland irrigation water management condition will reach unanimity gradually, water intake facilities erosion control technology will more and more have research and extension using value, progressively be subject to people's attention.
Intake is an important component part of low-pressure water delivery irrigation conduit.Due to the compliance of water delivery in pipeline system to landform, the pressure distribution of system differs greatly to open channel system, and adjusting, the control of the water yield are had relatively high expectations, so intake has wherein caused that people more pay close attention to.
Can stablize again research China of quota water intake facilities of water distribution for existing flush-prevention function in the starting stage, still not have ripe theory and product to come out.The water intake facilities using is at present all poor for the regulation and control ability of pipe-line system water yield, causes current comparatively remarkable to the problem of washing away of agricultural land soil, and the water yield of system is distributed and water management also very bothers.For this reason, in order to adapt to the requirement of current farmland irrigation water management, provide the water yield that needs distribution to farmland real-time and accurately, develop the quota intake matching with pipe-line system very necessary and very urgent.This is the key that reduces water outlet erosion control, improves field water effective rate of utilization, improves uniformity of irrigation water appilcation and reach design irrigating water quota etc.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of can erosion control again can quota water distribution farmland low-pressure delivery pipe spiral cover antiflushing type quota intake.
The purpose of this utility model is achieved through the following technical solutions: farmland low-pressure delivery pipe spiral cover antiflushing type quota intake, comprise low-pressure delivery pipe, it is characterized in that, be provided with inhalant region, exhalant region and checking motion, checking motion is arranged in exhalant region, inhalant region is connected with low-pressure delivery pipe and checking motion respectively, described inhalant region is by standpipe, reducer tee connects and composes, reducer tee is arranged on low-pressure delivery pipe bifurcation, described checking motion is by spiral cover, cylindrical shape Connection Block forms, the caping middle part of spiral cover inner side is provided with screw rod, described Connection Block is nested with and is connected on standpipe, Connection Block center is provided with the screw mount matching with screw rod, spiral cover passes through screw rod, screw mount is threaded with Connection Block, described screw rod bottom is provided with and prevents that screw rod from skidding off the alignment pin of screw mount.
Cementing connection between described Connection Block inwall and standing tube outer wall.
Described spiral cover is circular, and the internal diameter at spiral cover top is greater than the external diameter of Connection Block.
Described spiral cover, screw rod, alignment pin, Connection Block are that metal material is made.
Described spiral cover inside top is provided with sealing mat, and sealing mat is that elastomeric material is made.
The utility model top is a circular spiral cover, is fixed with a screw rod in the middle of spiral cover inner side, bottom be one for connecting the cylindrical shape Connection Block of standpipe and spiral cover.Because the internal diameter at spiral cover top is greater than the external diameter (thereby forming the mouth of a river) of Connection Block, the spiral cover lateral wall oppositely extending makes water outlet current contrary with the water (flow) direction of intaking, and by overcoat spiral cover on standpipe, intake base can be eliminated current excess energy.Thereby simultaneously corresponding with fixed distributed water flow by the size of the rotation spiral cover adjustable water outlet cross-section of river.
The directly rotation spiral cover size of the adjusting water outlet mouth cross-section of river automatically, the intake of different size model is corresponding with position and distributed water flow on the pipeline of place.Utilize the waterpower backsurging principle of overcoat spiral cover to eliminate pipeline pressure head more than needed, avoid in water intaking process, current directly wash away agricultural land soil and cause the destruction to water intake facilities.Alignment pin can prevent that spiral cover from coming off in use procedure, alignment pin position has determined spiro rod length and spiral cover maximum opening simultaneously, guarantee that the intake distributed water flow on diverse location is certain, solve well the antitheft problem with quota water distribution of intake in water management, guaranteed the uniformity of water distribution on irrigated area.Spiral cover of the present utility model, screw design are compared with other presser type intake, and stagnant water effect is better, rational in infrastructure, water flow stationary, and repercussion effect is remarkable.

The specific embodiment
Farmland low-pressure delivery pipe spiral cover antiflushing type quota intake, comprises low-pressure delivery pipe, inhalant region, exhalant region 6 and checking motion, and checking motion is arranged in exhalant region, and inhalant region is connected with low-pressure delivery pipe and checking motion respectively.
Inhalant region is connected and composed by standpipe 8, reducer tee 7, and reducer tee is arranged on low-pressure delivery pipe bifurcation.Checking motion is to be made up of spiral cover 5, cylindrical shape Connection Block 4, and the caping middle part of spiral cover inner side is provided with screw rod 1, and Connection Block is nested with and is connected on standpipe, cementing connection between Connection Block inwall and standing tube outer wall.
Connection Block 4 centers are provided with the screw mount 9 matching with screw rod, and spiral cover is threaded with Connection Block by screw rod, screw mount, and screw rod bottom is provided with and prevents that screw rod from skidding off the alignment pin 3 of screw mount.
Spiral cover is circular, and the internal diameter at spiral cover top is greater than the external diameter of Connection Block, thereby forms the mouth of a river.Spiral cover inside top is provided with sealing mat 2.Spiral cover, screw rod, alignment pin, Connection Block are that metal material is made, and sealing mat is that elastomeric material is made.
Current flow through standpipe, flow out from the space of screw mount, because the internal diameter at spiral cover top is greater than the external diameter of Connection Block, the spiral cover lateral wall oppositely extending makes water outlet current contrary with water inlet water (flow) direction, thereby drives screw rod in screw mount, to move up and down adjusting aperture by rotating spiral cover.
