Description
Technical field
The utility model relates to a kind of reduction valve, particularly about a kind of multi-function high-flow reduction valve being applicable to pipe irrigation system arm, belongs to agricultural water-saving irrigation field.
Background technique
In agricultural irrigation, uniformity of irrigation water appilcation is the important indicator weighing irrigation quality.But because terrain differences and stem respectively pour water community apart from equal reason apart from downstream, each cell entry place water pressure of pouring water can change, and then causes irrigation uniformity not meet code requirement.In order to effectively control the uniformity of irrigation water appilcation of whole irrigation system, installing voltage adjusting device at entrance branch place, community of respectively pouring water is a solution preferably, and the community inlet pressure that can ensure respectively to pour water is identical.
Now introduce many deficiencies that existing pressure regulator valve exists with reference to the accompanying drawings.As shown in figure 14, be a kind of monodrome territory of the prior art pressure regulator, mainly comprise the shell 1, the gaily decorated basket 2, regulation component 3 and the spring 4 that are jointly made up of 3, upper, middle and lower part.Its pressure regulation mechanism is: current enter regulation component 3 cavity flow to downstream through the gaily decorated basket 2, along with upstream pressure constantly increases, downstream pressure also increases thereupon, due to the effect of spring 4 power, before upstream pressure reaches certain certain value, regulation component 3 downstream keeps holding out against state with outlet always.When upstream pressure continues to increase, when the pressure acting on regulation component 3 downstream is greater than spring 4 initial compression stress and downstream pressure sum, pressure regulator starts to play regulating action, compressed at force action lower spring 4, regulation component 3 upstream moves, and now import discharge section area reduces, and loss of head increases, downstream pressure reduces, and reaches with this object controlling outlet pressure.
But this pressure regulator, once assemble, can only realize a kind of set pressure; And due to current by means of only regulation component cavity flow to downstream, can cause space waste, want to realize large discharge, whole equipment volume can be very large.
Again as shown in figure 15, for a kind of irrigation multi-domain adjustable compression release valve of the prior art, its pressure regulation mechanism is: when upstream has certain water pressure, current enter into water valve chamber 30 from water intake 19, flow control room 26 is entered again by irrigating gate 28, water outlet valve chamber 25 is entered again by bleeder 29, flow out from water outlet 20, along with the continuous increase of upstream pressure, downstream pressure also improves thereupon, due to the effect of spring 4 power, before upstream pressure reaches certain certain value, strut 14 and valve top 17 can not produce movement.When act on be greater than spring 4 power making a concerted effort on strut 14 and valve top 17 time, pressure regulator valve is started working, and valve top moves up, now discharge section area reduce, loss of head increase, outlet pressure reduce.On the contrary, when upstream pressure reduces, recover at total pressure head effect lower spring 4, valve top 17 is vacillated dynamic downwards, and discharge section area increases, and loss of head reduces, and outlet pressure increases, and ensures the stable of outlet pressure with this.There is a driveshaft 6 this pressure regulator valve the top, by regulating driveshaft 6, can change outlet set pressure.
But this reduction valve inflow-rate of water turbine only has 5 ~ 15m
3/ h, is difficult to the overcurrent requirement meeting existing irrigation system arm; The periphery of this reduction valve flow control room 26 is provided with 4 segmentation posts, and when current enter flow control room 26 by irrigating gate 28, segmentation post can play inhibition, and loss of head increases, and plays pressure regulation power higher.
And when above-mentioned two kinds of devices use on the tubing, must use with valve matched, after a rotation flow group irrigation terminates, need throttle down, namely above-mentioned two kinds of devices are not all closed and open function, therefore can not be used as valve and use.
Therefore, be badly in need of a kind of large discharge in prior art, outlet set pressure is adjustable and there is the irrigation system Zhi Guanyong reduction valve of opening and closing function.
