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 and withholds 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, and the accuracy of intake place water distribution directly has influence on scientific consumption of water management, the water rate in irrigated area, 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.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.
In the starting stage, be development in promote on research limit, limit for not only energy water but also the research China of quota intake that can stablize water distribution, still do not have ripe theory and product to come out.Though the intake using at present has regulation and control ability for pipe-line system water yield, but without measuring equipment in the situation that, cannot exactly the water yield of pipeline be distributed to each field as required, the water yield of system is distributed and water management still 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 in conjunction with piping transportation water irrigation feature that some are relatively simple for structure, practical, cost is lower, more current, the water yield water fetching device of function is very necessary and very urgent.This is the key that improves field water effective rate of utilization, raising uniformity of irrigation water appilcation, reaches design irrigating water quota and water outlet erosion control etc.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and the farmland low-pressure delivery pipe that a kind of not only energy water is provided but also can stablizes water distribution is withheld antiflushing type quota intake.
The purpose of this utility model is achieved through the following technical solutions: farmland low-pressure delivery pipe is withheld 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, the described control zone of withholding is provided with enclosing cover, alignment pin, tube connector and the delivery port that is arranged on enclosing cover sidewall, alignment pin is arranged on the tube wall of 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 moves up and down along chute by alignment pin.
Described enclosing cover inside top is provided with sealing mat.
Between described tube connector and standpipe, be provided with cementing connection.
Described standpipe, reducer tee, enclosing cover, tube connector are high-strength, age inhibiting ABS plastic material and make.
It is precast concrete material that the each parts of the utility model remove discharge bay, all the other materials are that plastic material is made, gauge tap is withheld by enclosing cover in its top, adopt enclosing cover, sealing mat to add outlet structure, under button, pressure External Force Acting, alignment pin moves up and down along fixing chute, thereby changes the size of delivery port, and water yield is reached unanimity.
The utility model connects low pressure pipeline system by reducer tee, directly at button, under the effect of pressure external force, can adjust the open and-shut mode at the mouth of a river, the size of the delivery port cross-section of river is by the concrete installation site on the pipeline of intake place, determine by the Hydraulic Design, realize intake and there is adjusting 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 utilization rate, also be beneficial to taking over of water rate, thereby reach the effect of water saving.The current of being gushed out by delivery port drop on discharge bay, utilize waterpower principle 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 position has determined enclosing cover open degree and delivery port maximum opening simultaneously, guarantee that the intake distributed water flow on diverse location is certain, solved well the antitheft problem with quota water distribution of intake in water management, guaranteed the uniformity of water distribution on irrigated area.The utility model is rational in infrastructure, water flow stationary, and local head loss is less, simple in structure, and cost is low, flexible operation, sealing mat sealing, good seal performance, is easy to safeguard.
