Description
Technical field
The utility model 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 utility model 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, in the time that 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, rotate because water velocity cannot drive sealing valve plate more slowly, 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.
