The purpose of this utility model is achieved through the following technical solutions: farmland can regulate flap type quota hydrant, comprise intake pipe, stopper, screw rod, flap, the bolt shell, handwheel, intake pipe is connected the lower end of bolt shell, stopper is connected the upper end of bolt shell, flap in the screw rod lower end is passed stopper and is arranged on the bolt shell is connected, the screw rod upper end connects handwheel, it is characterized in that being provided with the aperture indicator panel, the aperture indicator panel is arranged on the handwheel below and fixedlys connected with stopper, the aperture indicator panel is provided with positioning hole and aperture indicating lock set button, the cone segments of aperture indicating lock set button stretches into the bottom at positioning hole, described handwheel is provided with locating piece, and the positioning hole on locating piece and the aperture indicator panel is on same circumference.
Described bolt shell inwall is provided with and the airtight circle limit of flap coupling.
Be provided with the guiding device that the flap that is made of guiding groove and guide finger moves up and down between described bolt shell and the flap, guiding groove is arranged on the bolt shell inwall, and guide finger is connected on the flap.
Described aperture indicating lock set button is installed in by cone and spring horizontal in the button hole of aperture indicator panel and constitutes.
Circle limit horizontal position on the described bolt shell inwall is lower than the minimum point of bolt shell outlet.
The material of described intake pipe, bolt shell, stopper, screw rod, flap, bolt shell, handwheel is igelite.
The material of described spring is the stainless steel metal material.
Described circle limit is provided with seal ring.
The utility model is rational in infrastructure simple, manufactures and installs easily, and cost is low.Good integrity, the external force sealing, good sealing effect opens and closes flexibly, and easy to operate, usability is good.By the handwheel rotary screw, promote flap regulation and control water flow, light and handy convenient.When flap rose to required aperture position, locating piece slipped in the positioning hole in the aperture indicator panel, and extruding simultaneously provides corresponding aperture indicating lock set button, and the numeral on the button indicates the current aperture of hydrant position.The water outlet aperture different as need pressed current aperture indicating lock set button, and rotation hand wheel ejects to the aperture indicating lock set button that needs simultaneously.The quantity of aperture indicating lock set button is decided by the maximum quantity of intake on the aqueduct on the aperture indicator panel, intake position on the corresponding aqueduct of each gear positions; Calculate and the position of setting flap lifting by the loss of head of pipeline water delivery process.Thereby guarantee that different intake water outlet current are steady on the same pipeline water delivery, water yield unanimity.The utility model satisfies the demand of piping transportation water irrigation engineering construction of present farmland and management, can be widely used in farmland piping transportation water irrigation engine request.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 intake pipe, 2 bolt shells, 3 guide fingers, 4 guiding grooves, 5 flaps, 6 screw rods, 7 stoppers, 8 aperture indicating lock set buttons, 9 aperture indicator panels, 10 handwheels, 11 locating pieces, 12 positioning holes, 13 seal rings.
Specific implementation method
Intake pipe 1 is connected the lower end of bolt shell 2, stopper 7 is connected the upper end of bolt shell 2, flap 5 in screw rod 6 lower ends are passed stopper and are arranged on the bolt shell is connected, the screw rod upper end connects handwheel 10, aperture indicator panel 9 is arranged on the below of handwheel and fixedlys connected with stopper 7, establish positioning hole 12 and aperture indicating lock set button 8 on the aperture indicator panel, aperture indicating lock set button is installed in by cone and spring horizontal in the button hole of aperture indicator panel and constitutes, button hole communicates with positioning hole 12, the cone segments of aperture indicating lock set button stretches into the bottom at positioning hole, establish locating piece 11 on the handwheel 10, the positioning hole on locating piece and the aperture indicator panel is on same circumference.Establish on the bolt shell inwall and the airtight circle limit of flap coupling, circle limit horizontal position is lower than the minimum point of bolt shell outlet, and circle is established seal ring 13 on the limit.Establish the guiding device that the flap that is made of guiding groove 4 and guide finger 3 moves up and down between bolt shell and the flap, guiding groove is arranged on the bolt shell inwall, and guide finger is connected on the flap.
When using operation,, promote flap 5 regulation and control water flows by handwheel 10 rotary screws 6.When flap 5 rose to required aperture position, locating piece 11 slipped in the positioning hole in the aperture indicator panel 9, and extruding simultaneously provides corresponding aperture indicating lock set button 8, and the numeral on the button indicates the current aperture of hydrant position.The water outlet aperture different as need pressed current aperture indicating lock set button 8, and rotation hand wheel 10 ejects to the aperture indicating lock set button 8 that needs simultaneously.The quantity of aperture indicating lock set button 8 is decided by the maximum quantity of intake on the aqueduct on the aperture indicator panel 9, intake position on the corresponding aqueduct of each gear positions; Calculate and the position of setting flap lifting by the loss of head of pipeline water delivery process.Thereby guarantee that different intake water outlet current are steady on the same pipeline water delivery, water yield unanimity.
The quantity of hydrant of working simultaneously on the adjusting aperture that hydrant has and the pipeline is identical, can be according to the on-the-spot artificial corresponding aperture of setting in hydrant position during use.Be installed on pipeline first hydrant foremost, be set at first order aperture at the scene, corresponding hydrant outlet flow cross-section minimum is to eliminate maximum working head more than needed.And be installed in last hydrant of pipe end, then be set at maximum opening at the scene, corresponding hydrant outlet flow cross-section maximum, the hydrant aperture of other working positions is can be successively on-the-spot to be set, and hour can have and the identical feedwater flow of pipeline head end hydrant to guarantee pipe end hydrant working head.
The difference of the utility model and other low pressure pipeline hydrant is can be according to the length of the arm of working in the engineering reality and caliber, work simultaneously hydrant quantity and farmland irrigating water quota, select can regulate flap type quota hydrant, regulate the hydrant aperture by the on-the-spot disposable setting in hydrant working position again and also locked.Avoid in water utilizing process, constantly change the unsettled shortcoming of water flow that causes because of the pipeline pressure instability with along journey, by hydrant stable flow rate and water distribution time, just can obtain offering the irrigation quantity of irrigated farmland from hydrant, the amount of realization hydrant, control integrated, be convenient to the irrigation water management, reduce water yield waste, help irrigating meterage.
