Abstract
The invention discloses a floating type multifunctional hydrant for farmland pipeline irrigation. The floating type multifunctional hydrant is mainly composed of an upper hydrant body and a lower hydrant body. The floating type multifunctional hydrant is characterized in that a semi-fixed type split combined structure is adopted in the hydrant, the lower hydrant body is fixed below the ground, a floating type water check valve is arranged in the lower hydrant body, the lower hydrant body is placed in a concrete protective pipe and connected with a pipeline through a three-way vertical pipe to form a fixing device used for supplying water to a farmland; the upper hydrant body is matched with the lower hydrant body. The floating type multifunctional hydrant is simple in structure, convenient and fast to assemble and install, long in service life and high in cost performance. In a non-irrigation season, the lower hydrant body is fixed in the concrete protective pipe below the ground, so the problems that the hydrant affect agricultural machinery cultivation and can be collided and damaged easily are solved. The floating type water stop technology is adopted in the lower hydrant body, and an automatic closing function is achieved through buoyancy of water in the pipeline. The floating type water stop structure has functions of a suction and exhaust valve, and solves the problem that the pipeline is damaged due to water hammer impact and backwater negative pressure.
Description
Technical field
The invention belongs to agricultural irrigation technology.
Background technology
Hydrant is commonly called as delivery port, has irrigation system water delivery water distribution earthward in pipeline irrigation engineering, switch restraining, and metering water quantity, protects pipeline and guarantees to irrigate the critical functions such as order, therefore becomes one of affiliated facility of most critical in pipeline irrigation engineering.
At present in engineering reality, traditional hydrant structurally has movable type, semi-fixed type, the form such as fixed, water-proof scheme has flat valve type, butterfly valve type, ball-valve type, wire cover formula etc., make material and have cast iron, PE, PVC, fiberglass etc., various informative, material differs, the following six aspect problems of ubiquity:
The one, external pressure sealing, manual-lock, often not tight because closing, pressure is excessive, produces the factors such as water hammer, causes loosening leaking, and before irrigating, needs to check one by one whether fasten, and time-consuming, management difficulty is larger;
The 2nd, side water exit, more than can only being installed on ground, affects farming, is destroyed situation comparatively serious by agricultural machinery;
The 3rd, Wrench for opening is easy to copy, and disorderly opens that disorderly to open phenomenon comparatively serious, cannot have order to irrigate by rotation flow system;
The 4th, function singleness, can only manually open, close, and cannot realize automatically and closing, water metering, air intake-exhaust, the comprehensive functions such as protection pipeline.
The 5th, without metering facility, cannot realize water metering to family, cannot realize by side's charge to family;
The 6th, protective device mostly is scene and builds by laying bricks or stones, time-consuming, takies farmland;
The immediate prior art of the present invention is that patentee Song Qing ripple is applied for " field pipeline irrigation waterworks ", (patent No. ZL201210065481.5) on March 14th, 2012.It is perfect that the Multifunction water plug of above-mentioned patented invention has been tending towards in function, but structure relative complex, subject matter is: 1. lower bolt sealing form is interior pressure sealing, sealing valve plate is hemispherical, the screw rod that opening and closing rely on the inner cross hang nut of lower bolt to be connected with hemispherical sealing valve plate bottom, rotation completes, when inside water pressure is larger (while being generally greater than 0.4Mpa), open moment larger, open more difficult; 2. automatic closing function relies on a point hydrofoil for hemispherical water check valve panel edges under flow action, to drive valve plate inhour to rotate, then realize automatic closing function, when relatively hour (while being generally less than 0.01Mpa) of hydraulic pressure, because water velocity cannot drive sealing valve plate more slowly, rotate, cannot realize automatic closing function; 3. point hydrofoil at hemispherical water check valve panel area edge and hemispherical valve plate bottom concave structure, while causing operation, flow condition is poor, and the loss of flood peak is larger, causes key vibrations because producing negative pressure simultaneously.4. because air inlet and exhaust valve is placed in the ball chamber of hemispherical sealing valve plate top downside, be subject to spatial limitation air vent less, capacity relative deficiency, gas in pipelines discharge is not smooth, so that still have gas and water body to discharge while normally going out water running simultaneously, causes key vibrations.When simultaneity factor is closed, air inlet effect is also relatively bad.
Summary of the invention
The object of this invention is to provide a kind of float type field pipeline irrigation Multifunction water plug, to address the above problem.
The present invention is mainly comprised of upper bolt and lower bolt, solve the technical scheme that its technical problem adopts: this hydrant adopts semi-fixed type Split assembled structure, lower bolt is fixed on below ground, float type water check valve is set in lower bolt, lower bolt is placed in concrete protection tube, be connected with branch pipe tee connection standpipe, form the fixture supplying water to field; Lower bolt has adopted buoyancy aid sealing principle, has realized air inlet, exhaust, automatic closing function; Upper bolt and lower bolt are supporting, and upper bolt bottom arranges cross hang muscle and opens drive nut, have formed the specific purpose tool of downward promotion buoyancy aid, unlatching lower bolt.
