Abstract
The utility model relates to a farmland low-pressure pipeline floating ball ration water supply device, belonging to the technical field of farmland pipeline water delivery irrigation engineering. The farmland low-pressure pipeline floating ball ration water supply device comprises a water inlet pipe, a gate valve region and a water outlet pipe which are fixedly connected with each other in sequence from bottom to top. The utility model is characterized in that the gate valve region is provided with a ball grid, a taper pipe, a floating ball, a spring, a fixed rod and a guide rod; the floating ball and the spring are sheathed on the guide rod in a penetrating manner and arranged in the taper pipe; the ball grid and the fixed rod are respectively arranged on the bottom and top of the taper pipe; the spring and the guide rod are connected with the fixed rod; and the taper pipe is connected with the water inlet pipe and the water outlet pipe through flanges. The utility model has the advantages of reasonable and simple structure, smooth water flow and small local head loss, is easy in production and convenient in installation, maintenance and management, and is beneficial to charging the water rate; and the utilization ratio of irrigation water is improved, thereby achieving the effect of water saving. The gate valve region is of a structure with the taper pipe and the floating ball, the floating ball pushes the spring to move up and down along the guide rod under the actions of different water pressures, thereby changing the size of a water outlet, so that the water outflow quantity are appropriately consistent.
Description
Technical field
The utility model relates to the pipeline quota water dispensing apparatus of farmland piping transportation water irrigation system, belongs to farmland piping transportation water irrigation field of engineering technology.
Background technology
The waterworks of low pressure pipe irrigation system are the critical facilitys from pipeline to the farmland water distribution, and science water management, water rate that the accuracy of waterworks 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.
Waterworks are important component parts 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 waterworks have wherein caused people's more concern.
Be in the starting stage for the research China that can water gaging can stablize the quota waterworks of water distribution again, still do not have mature theory and product to come out.Though the waterworks that use have adjusting and control ability for the pipe-line system water yield at present, but under the situation of no measuring 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 waterworks 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 utility model 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 waterworks 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 waterworks, comprise the water inlet pipe, gate valve district and the outlet pipe that install and fix connection from bottom to top successively, it is characterized in that described gate valve district is provided with ball bar, Taper Pipe, ball float, spring, dead lever and guide rod, ball float and spring are set on the guide rod and are arranged in the Taper Pipe, ball bar and dead lever are separately positioned on the bottom and the top of Taper Pipe, spring is connected with dead lever with guide rod, adopts flange to be connected between Taper Pipe and water inlet pipe and the outlet pipe.
The material of described water inlet pipe, outlet pipe, ball bar, Taper Pipe, ball float, dead lever and guide rod is igelite, and the material of spring is the stainless steel metal material.
The big opening end of described Taper Pipe connects water inlet pipe downwards, and the osculum end of Taper Pipe upwards connects outlet pipe.
The section of described dead lever 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 availability, also is beneficial to taking over of water rate, thereby reaches the effect of water saving.The gate valve district adopts Taper Pipe to add the ball float structure, and under different effect of water pressure, ball float promotes spring and moves up and down along guide rod, thereby changes the size of delivery port, and water flow is reached unanimity.
The essential distinction of the utility model and other waterworks 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, select corresponding waterworks according to the quota feedwater flow, then be in operation and guarantee each waterworks 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 waterworks reaches unanimity,, just can know what of each waterworks irrigation quantity to have made things convenient for management as long as note irrigation period, improved the irrigation water availability, also be beneficial to taking over of water rate, thereby reach water saving, save the effect of propping up.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1 water inlet pipe, 2 ball bars, 3 Taper Pipes, 4 ball floats, 5 springs, 6 dead levers, 7 outlet pipes.
Embodiment
Below in conjunction with accompanying drawing concrete case study on implementation of the present utility model is described.
Connect and compose the gate valve district by ball bar 2, Taper Pipe 3, ball float 4, spring 5, dead lever 6 and guide rod installation, ball float and spring are set on the guide rod and are arranged in the Taper Pipe, ball bar and dead lever are separately positioned on the bottom and the top of Taper Pipe, spring is connected with dead lever with guide rod, adopts flange to be connected between Taper Pipe and water inlet pipe and the outlet pipe.The big opening end of Taper Pipe connects water inlet pipe 1 downwards, and the osculum end of Taper Pipe upwards connects outlet pipe 7.The section of dead lever is the T type.The material of water inlet pipe, outlet pipe, ball bar, Taper Pipe, ball float, dead lever and guide rod is polyvinyl chloride plastic, and Taper Pipe 3 adopts the manufacturing of UPVC material.The ball bar 2 of Taper Pipe 3 bottoms can support ball float.Ball float can be free to slide on guide rod under different effect of water pressure, regulates the gap between ball float and the Taper Pipe wall, reaches to adjust mouth of a river size automatically the flow of control water dispensing apparatus.
