Abstract
The utility model provides a float ball quota hydrant for a farmland low pressure pipeline, belonging to the field of farmland pipeline water delivery and irrigation engineering technology. The float ball quota hydrant in the utility model comprises a water inlet pipe, a valve area, and a water outlet pipe successively installed from bottom to top and fixedly connected, the valve area is provided with a butterfly valve, a ball grid, a taper pipe, a float ball, a spring, a fixed rod, and a guide rod, the ball float and the spring sleeve the guide rod and are disposed in the taper pipe, the ball grid and the fixed rod are respectively disposed at the bottom and the upper part of the taper pipe, the spring and the guide rod are fixedly connected with the fixed rod, the taper pipe is connected with the water outlet pipe via a flange. The float ball quota hydrant for a farmland low pressure pipeline is advantaged by simple and reasonable structure, easy production and manufacture, convenient installation and maintenance; stable flow, and smaller local head loss, the float ball quota facilitates management, improves utilization rate of irrigation water, and is beneficial to water rate collection, thereby reaching effect of saving water, The switch is controlled by the butterfly valve in the valve area, the structure of the taper pipe adding the float ball is adopted, under effect of different hydraulic pressures, the float ball pushes the spring to move up and down along the guide rod, thereby changing size of water outlet, making water outlet amount tend to be consistent, and realizing measurement and control integration of hydrant.
Description
Technical field
The utility model relates to the pipeline quota water-matching installation of farmland piping transportation water irrigation system, belongs to farmland piping transportation water irrigation field of engineering technology.
Background technique
The hydrant of low pressure pipe irrigation system is the critical facility from pipeline to the farmland water distribution, and science water management, water rate that the validity of hydrant place water distribution directly has influence on the irrigated area reclaim, even can have influence on applying of advanced irrigation technique.Along with the farmland irrigation water management condition will reach unanimity gradually, the quantitative distribution apparatus technology of distributing pipe line will more and more have the research and extension using value, progressively be subject to people's attention.
Hydrant is an important component part of low-pressure water delivery irrigation conduit.Because water delivery in pipeline system is to the adaptability of landform, the relative open channel of the pressure distribution of system system differs greatly, and the adjusting of the water yield, control are had relatively high expectations, so hydrant has wherein caused people's more concern.
Also be in the starting stage for the research that can water gaging can stablize the quota hydrant of water distribution again, still do not have mature theory and product to come out.Though the hydrant that uses has adjusting and control ability for the pipe-line system water-outlet quantity at present, but under the situation of no metering equipment, can't exactly the water yield of pipeline be distributed to each field piece 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 the farmland real-time and accurately, it is then very necessary and very urgent to develop the quota water distribution, the hydrant that match with pipe-line system.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.
The model utility content
The purpose of this utility model is in order to solve the deficiency that above-mentioned prior art exists, satisfy farmland piping transportation water irrigation water management, provide a kind of simple to operate, water distribution is accurate, and what be easy to safeguard can stablize the farmland low pressure pipeline ball float quota hydrant of water distribution again by water gaging.
The purpose of this utility model is achieved in that a kind of farmland low pressure pipeline ball float quota hydrant, comprise the intake pipe, valve district and the outlet pipe that install and fix connection from bottom to top successively, it is characterized in that described valve district is provided with butterfly valve, ball bar, Taper Pipe, ball float, spring, fixing rod and guide rod, ball float and spring are set on the guide rod and are arranged in the Taper Pipe, ball bar and fixing rod are separately positioned on the bottom and the top of Taper Pipe, spring is connected with fixing rod with guide rod, is connected by flange between Taper Pipe and the outlet pipe.
The material of described intake pipe, outlet pipe, ball bar, Taper Pipe, ball float, fixing rod and guide rod is an igelite, and the material of spring is the stainless steel metal material.
The big opening end of described Taper Pipe connects butterfly valve downwards, and the osculum end of Taper Pipe upwards connects outlet pipe.
The section of described fixing rod is the T type.
The utility model is rational in infrastructure simple, manufactures easily, and convenient for installation and maintenance, current are steady, and local head loss is less, has made things convenient for management, has improved the irrigation water utilization ratio, also is beneficial to taking over of water rate, thereby reaches the effect of water saving.The valve district adopts Taper Pipe to add the ball float structure, under different effect of water pressure by the butterfly valve control switch, ball float promotes spring and moves up and down along guide rod, thereby change the size of water outlet, water flow is reached unanimity, butterfly valve can play the effect of stable water inlet fluidised form simultaneously.The essential distinction of the utility model and other hydrant is to adjust automatically the size at the mouth of a river, utilize the waterpower principle to eliminate pipeline pressure head more than needed, avoid in water utilizing process, constantly change the unsettled shortcoming of water flow that causes because of the pipeline pressure instability with along journey, as long as before pouring water, manually set feedwater flow at every turn according to the water distribution requirement, then be in operation and guarantee each hydrant water flow stable and consistent all on the pipeline, improved irrigation uniformity, made it can satisfy the requirement of quota water distribution.And, because the flow of each hydrant reaches unanimity, the amount that has realized hydrant is control integrated, as long as note irrigation period, just can know what of each hydrant irrigation quantity to have made things convenient for water management, improve the irrigation water utilization ratio, be beneficial to taking over of water rate, thus reach water saving, the joint effect.
