Abstract
The invention provides a multifunctional hydrant which comprises a water distribution cap, an opening/closing cover, a hydrant main body and steel spring clamps, wherein the opening/closing cover is mounted between the water distribution cap and the hydrant main body; the water distribution cap is connected with the hydrant main body through the steel spring clamps arranged on the periphery of the hydrant main body; and the water distributing cap, the opening/closing cover and the hydrant main body are made of steel or cast iron. The multifunctional hydrant provided by the invention is made of steel or cast iron instead of glass fiber reinforced plastic and PVC, so that the operability of the hydrant is improved, the service life of the hydrant is prolonged, and the maintenance rate is lowed; a built-in tripod which is formed by one-step casting is fixed in the hydrant main body to make a lifting screw firm and durable and directly act on the opening/closing cover to achieve the effects of free and flexible opening and closing and high leakproofness; and since the water distribution cap is connected with the hydrant main body through the steel spring clamps, the water distribution cap and the hydrant main body can be easily separated, the operation is simple and is easy to master, and the disadvantage that pipe fittings are easily broken because a conventional hydrant is opened by tools such as a spanner is reduced.
Description
Technical field
The invention belongs to agricultural, forestry irrigation equipment technical field, it is related to a kind of Multifunction water plug.
Background technology
From the beginning of last century the nineties, the whole nation carries out water-saving irrigation experiment in fields such as agricultural, forestry, successively introduction tube
The advanced water-saving technology such as filling, slight irrigation, sprinkling irrigation, is achieved breakthrough with the high-new water-saving technique adoption that slight irrigation test spread is attached most importance to
Progress.Pipe is filled, micro-pipe water-saving irrigation technique is applied to field, greening forest belt, can be effectively improved farmland, forestry irrigation conditions,
Improve irrigation water using efficiency it is ensured that effective performance of farm field irrigation drainage system overall efficiency, improve agricultural and combat a natural disaster mitigation ability,
Improve labor productivity, ensured the smooth realization of agricultural produce, increasing peasant income, growth of agricultural efficiency, for protection and improve me
Area's comprehensive grain production ability, safeguards national food security, promotes national economy and social development tool to be of great significance.
Meanwhile, can make crop in good time, appropriate irrigate, apply fertilizers scientifically, increase grain output.According to the data of summary, efficient water-saving irrigation work
Journey with can making every mu of the farmland 45-50% that economizes on water, saves fertilizer 50%, and economize on electricity 40-50 degree, saves labour 10, increases production 18-
30%.
So far, used in agricultural, field of forestry are irrigated, water saving earth material and valve control equipment are two kinds of materials, and one
Plant and utilize die casting and molding for igelite, model φ 63, multiple PVC pipe of φ 75 are formed by connecting, another kind of
It is formed by connecting for glass clamp sand material use die casting and molding pipe fitting, there is drawback a lot, mainly have at following 5 points：One is long
Phase is exposed under ultraviolet irradiation, and validity period is short, must change in 2 to three years；Two be in subsoil water more contain silt, two to
Lead in 3 years open and close dumb it is necessary to change；Three is that after pipe fitting connects, fore-and-aft distance is longer, causes farmland, greenbelt to be irrigated
There is blind area, during the operation of field agricultural machinery, easily it is damaged, turnover rate is high meanwhile；Four is that tubing model is various, pipe fitting
More, lead to connecting sewing many, cause leak source more, easily cause water, fertilizer, the waste of electricity during irrigation, and maintenance rate is high；Five is existing
Use material, irrigation method single it is impossible to meet the demand of multiple irrigation methods, cause land utilization ratio can not effectively carry
Height, field water channel still needs to retain, and open fire irrigates to remain unchanged to be existed, however it remains water resource waste phenomenon.
So far, in agricultural, field of forestry are irrigated, the water saving earth material that pipe fills, micro-pipe uses, valve control equipment are used
Material function single, operability is poor, poor practicability, short life, repair and replacement rate are high.
