Description
Technical field
The present invention relates to the accessory of a kind of farmland low pressure pipe irrigation system, be specifically related to a kind of farmland low-pressure delivery pipe and withhold antiflushing type quota intake, belong 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, and the accuracy of intake place water distribution directly has influence on the scientific consumption of water management in irrigated area, water rate, even can have influence on applying of advanced irrigation technique.Along with farmland irrigation water management condition will reach unanimity gradually, the quantitative distribution apparatus technology of distributing pipe line will more and more have research and extension using value, progressively be subject to people's attention.
Quota intake is an important component part of low-pressure water delivery irrigation conduit.Because water delivery in pipeline system is to the compliance of landform, the pressure distribution of system is comparatively large to open channel systematical difference, and adjustment, the control overflow of the water yield are higher, more pay close attention to so intake wherein causes people.
Starting stage is in for not only energy water but also the research China of the quota intake stablizing water distribution, is development in research limit, limit is promoted, does not still have ripe theory and product to come out.Though the intake of current use has regulation and control ability for pipe-line system water yield, but when without measuring equipment, exactly the water yield of pipeline cannot be distributed to each field as required, water operation and the water management of system still extremely bother.For this reason, in order to adapt to the requirement of current farmland irrigation water management, the water yield needing to distribute is provided to farmland real-time and accurately, develop in conjunction with piping transportation water irrigation feature that some are relatively simple for structure, practical, cost is lower, the more current of function, water yield water fetching device are then very necessary and very urgent.This is the key improving field water effective rate of utilization, improve uniformity of irrigation water appilcation, reach design irrigating water quota and water outlet erosion control etc.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, the farmland low-pressure delivery pipe providing a kind of not only energy water but also can stablize water distribution withholds antiflushing type quota intake.
The object of the invention is to be achieved through the following technical solutions: farmland low-pressure delivery pipe withholds antiflushing type quota intake, comprise low-pressure delivery pipe, it is characterized in that, be provided with inhalant region, exhalant region and withhold control zone, withholding control zone is arranged in exhalant region, inhalant region is respectively with low-pressure delivery pipe with withhold control zone and be connected, described inhalant region is connected and composed by standpipe and reducer tee, reducer tee is arranged on low-pressure delivery pipe bifurcation, described exhalant region is the discharge bay that precast concrete builds up, described control zone of withholding is provided with enclosing cover, alignment pin, tube connector and the delivery port being arranged on enclosing cover sidewall, on the tube wall that alignment pin is arranged on enclosing cover and protruded tube inwall, tube connector is nested with and is connected on described standpipe, the outer wall of tube connector is provided with chute, enclosing cover is nested with on tube connector, alignment pin is placed in chute, enclosing cover is moved up and down along chute by alignment pin.
Described enclosing cover inside top is provided with sealing mat.
Described tube connector be provided with cementing connection between standpipe.
Described standpipe, reducer tee, enclosing cover, tube connector are high-strength, age inhibiting ABS plastic material and make.
It is concrete soil material that each parts of the present invention remove discharge bay, all the other materials are that plastic material is made, gauge tap is withheld by enclosing cover in its top, employing enclosing cover, sealing mat add outlet structure, under button, pressure External Force Acting, alignment pin moves up and down along fixing chute, thus changes the size of delivery port, and water yield is reached unanimity.
The present invention connects low pressure pipeline system by reducer tee, directly at button, the open and-shut mode at the mouth of a river can be adjusted under the effect of pressure external force, the size of the delivery port cross-section of river is by the concrete installation site on the pipeline of intake place, determined by the Hydraulic Design, realize intake and there is adjustment simultaneously, the function of control and the quota allocation water yield, the flow of each like this intake reaches unanimity, as long as record irrigation period, just can know the number of each intake irrigation quantity, facilitate management, improve irrigation water using efficiency, also taking over of water rate is beneficial to, thus reach the effect of water saving.The current gushed out by delivery port drop on discharge bay, utilize waterpower principle to eliminate pipeline to have more than needed pressure head, avoid in water intaking process, current directly wash away the destruction that agricultural land soil causes water intake facilities, alignment pin position determines enclosing cover length and delivery port maximum opening simultaneously, ensure that the intake distributed water flow on diverse location is certain, solve that intake in water management is antitheft joins water problem with quota well, ensure that the uniformity of water distribution on irrigated area.The present invention is rational in infrastructure, water flow stationary, and local head loss is less, and structure is simple, and cost is low, flexible operation, sealing mat sealing, good seal performance, is easy to safeguard.
