Description
Technical field
The utility model relates to a kind of flow regulator that is used for irrigation system.
Background technology
Flow regulator is the important component part of irrigation system, and it mainly acts on is the uniformity of pouring water that improves irrigator, thereby improves the irrigation uniformity of whole irrigation system.The principle of flow regulator is by the effect of water flow pressure to its internal elastomeric, runner (or aperture) alteration of form or discharge section area are changed, promptly when pressure reduces, increase discharge section area, when pressure increases, reduce discharge section area, make flows such as water dropper, mini sprinkler, tubule irrigator keep stable automatically, it is more even that water distribution is got.Existing flow regulator is slice structure (as shown in Figure 1 and Figure 2), and its elastomer is an elastomeric pad.When pressure increased, flexure strip was pressed towards runner one side (as Fig. 3), and flow area is reduced, and kept stability of flow; When pressure reduced, flexure strip was pressed runner one side (as Fig. 4) dorsad, and flow area is increased, and kept stability of flow.The chip flow regulator is mainly used in pressure compensation douche.The subject matter of the chip flow regulator existence of using at present is: when adjustment state, the runner under the elastomeric pad is little, stops up easily; Adjustable range is little; The flow passage structure design is complicated.
Summary of the invention
Characteristics such as the purpose of this utility model is that a kind of flow regulator will be provided, and it has the obstruction of being difficult for, and adjustable range is big.
Comprise in order to reach the technical scheme that the purpose of this utility model takes: water inlet 1, delivery port 5, tubular type overcoat 2, it is characterized in that, be provided with spool 4 in this tubular type overcoat 2, this spool 4 has axial groove 6 by an end of water inlet 1, the other end is provided with axial hole 7, axial groove 6 and axial hole 7 communicate, and an end that has axial groove 6 at this spool 4 is with elastic tube 3, and axial hole 7 communicates with delivery port 5.
In the above-mentioned flow regulator, the connected mode of tubular type overcoat 2 and spool 4 is for being threaded or plug-in type.
In the above-mentioned flow regulator, water inlet 1 and tubular type overcoat 2 can be integral type, and delivery port 5 can be integral type with spool 4.
In the above-mentioned flow regulator, axial groove 6 is provided with boss 8.
In the above-mentioned flow regulator, the material of elastic tube 3 is rubber or silica gel or latex.
In the above-mentioned flow regulator, water inlet 1 and delivery port 5 are the truncated cone-shaped of hollow.
The utlity model has following advantage:
(1) the pressure regulation scope increases, and can reach 4～40 meters heads.
(2) range of flow increases, can be between 30L/h～1000L/h scope.
(3) flow passage structure simplicity of design, manufacturing process is simple.
(4) applied widely, can be applicable to microspray irrigation, tubelet effluent filling and low pressure sprinkling irrigation.
(5) low cost of manufacture is convenient to promote and use.

Specific embodiments
Below in conjunction with accompanying drawing the utility model flow regulator is further described.
As shown in Figure 8, this flow regulator is a tubular structure, mainly comprises tubular type overcoat, spool, elastic tube three parts.1 is water inlet among the figure, and 2 is the tubular type overcoat, and 4 are spool (seeing Fig. 5, Fig. 6 and Fig. 7), and 3 for being enclosed within the elastic tube on the spool 4, and 5 is delivery port, and 6 is the axial groove of opening at spool 4 one ends, and 7 for being located at the axial hole of the spool other end, and axial groove 6 and axial hole 7 communicate; 8 is boss, utilizes the height difference of this boss can realize different flows.In the present embodiment, water inlet and tubular type overcoat, and delivery port and spool be integral type, certainly, they also can be split type.The connected mode of tubular type overcoat 2 and spool 4 is for being threaded or plug-in type.
The operation principle of the utility model flow regulator:
(see figure 9) when pressure increases, because the elastic tube outside is a hydrostatic pressure, its pressure increases many; And the elastic tube inboard is a flowing pressure, and its pressure increases few; So in the inside and outside formation pressure differential of this tube wall, outside pressure is big, makes tube wall press to the inboard, i.e. runner one side, thus reduce the discharge section area of runner, keep the stable of flow.
(see figure 10) when pressure reduces, because the elastic tube outside is a hydrostatic pressure, its pressure reduces many; And the elastic tube inboard is a flowing pressure, and its pressure reduces few; So in the inside and outside formation pressure differential of this tube wall, inside pressure is big, make tube wall press to the outside, thereby increase the discharge section area of runner, keep the stable of flow.
Because the utility model has adopted tubular structure, the pressure regulation scope is 4～40m head, flow 30L/h～1000L/h.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
