Abstract
The utility model provides a combined type venturi fertilization valve. A water flow control valve and a venturi control valve are connected in parallel, the fertilization uniformity is controlled by the synergic adjustment of water stream and liquid fertilizer, the utility model is especially suitable for the quantitative control of micro irrigation fertilization and spray irrigation fertilization. The structure of the combined type venturi fertilization valve comprises a water inlet pipe and a water outlet pipe mounted on an irrigation pipeline and the water flow control valve installed between the water inlet pipe and the water outlet pipe. A venturi tube is connected on branch pipes provided on two sides of the water flow control valve, and the elevator pipe part of the venturi tube is provided with a liquid fertilizer control valve which is connected with a liquid fertilizer storage tank. The utility model can effectively assure the balanced output and the quantitative control of the liquid fertilizer, having larger actual meaning of realizing accurate agricultural metering control. Synchronously for additional power is of no need, the fertilization valve of the utility model is of lower manufacturing and using cost, which is good for popularity and application in country.
Description
Technical field
The utility model relates to a kind of quantitative fertilization device that is used to irrigate, and is the matching component of slight irrigation, sprinkling irrigation, belongs to agricultural water-saving irrigation mechanized equipment technical field.
Background technology
Along with the popularization and application of water-saving irrigation technique, utilize irrigating facility fertilising or supporting with it fertilizer apparatus also to appear at more and more in the agricultural equipment, routine does not add outer power irrigation has two kinds with fertilizer apparatus, and a kind of is differential, and a kind of is venturi type.Though this dual mode can be injected into solution in the irrigation water in the irrigation process effectively, but also have fertilising concentration and the unmanageable defective of fertilizing amount: differential fertilizer apparatus injects irrigation water when the fertilising process begins fertilizer solution concentration is the highest, carrying out along with the process of irrigation, part irrigation water enters into the liquid fertilizer basin and a jar interior fertilizer solution concentration is reduced, and therefore the concentration of differential fertilizer apparatus solution in whole fertilising process is a variable.The venturi type fertilizer apparatus is difficult to hold in the flow velocity and the relation between the solution soakage of irrigation advance during through Venturi throat, is difficult for realizing quantitatively control.The patent applicant has applied for once that in order to address the above problem the patent No. is 02246740.8 water driven quantitative fertilizer spreader, do not having under the situation of additionaling power, and be that power is realized quantitative fertilization with the irrigation water.
Summary of the invention
The purpose of this utility model is to provide a kind of combined type venturi fertilising valve, water flow control valve and the combination of venturi control valve are provided with, by the collaborative uniformity of adjusting current and liquid fertilizer flow-control fertilising, be particularly useful for the quantitative control of slight irrigation, sprinkler irrigation fertilization.
The technical solution of the utility model is achieved in that this combined type venturi fertilising valve, the structure of valve of it is characterized in that applying fertilizer comprises the water inlet pipe and water outlet pipe that is installed on the irrigation pipeline, be arranged at the water flow control valve between the water inlet pipe and water outlet pipe, connect Venturi tube on the arm of water flow control valve both sides setting, the trunnion portion of Qiu Liguan is provided with the liquid fertilizer control valve that is connected with the liquid fertilizer basin.
The spool of the water flow control valve of described combined type venturi fertilising valve is a ball valve, the valve of plunger valve or other type.
The utility model is the control liquid fertilizer export technique scheme of power with water owing to having adopted, can guarantee the balanced output of liquid fertilizer effectively, quantitatively control, to realizing that the precision agriculture measure control has big realistic meaning, simultaneously owing to do not need additionaling power, the manufacturing cost and use cost of the utility model fertilising valve is all lower, helps in the rural area popularization and application.

Among the figure: 1, water inlet 2, end socket 3, sealing gasket 4, fertilizer delivering pipe 5, liquid fertilizer control valve 6, Venturi tube 7, water flow control valve 8, delivery port 9, spool
Embodiment
The main innovate point of combined type venturi fertilising valve shown in Figure 1 is that water flow control valve 7, liquid fertilizer control valve 5 are provided with Venturi tube 6 combinations, reaches uniform of application by flow and the liquid fertilizer flow of adjusting irrigation water.During fertilising, water flow control valve is partially or completely closed, the conducting of liquid fertilizer control valve, with the liquid fertilizer sucking-off, the flow that enters Venturi tube by the control irrigation water reaches the purpose of controlling the liquid fertilizer flow to irrigation water through Venturi tube, realizes the quantitative and even fertilising.In the time of need not applying fertilizer, water flow control valve 7 complete conductings, liquid fertilizer control valve 5 is closed.The liquid fertilizer basin need not overhead setting or increases complicated pressure compensator.
The utility model is simple in structure, and is easy for installation, the setting of can connecting on irrigation pipeline.
Claims (2)
1, combined type venturi fertilising valve, the structure of valve of it is characterized in that applying fertilizer comprises the water inlet pipe and water outlet pipe (1,8) that is installed on the irrigation pipeline, be arranged at the water flow control valve (7) between the water inlet pipe and water outlet pipe, connect Venturi tube (6) on the arm of water flow control valve both sides setting, the trunnion portion of Venturi tube is provided with the liquid fertilizer control valve (5) that is connected with the liquid fertilizer basin.
