Abstract
The utility model relates to a fertilizer injector, in particular to a metering type Venturi fertilizer injector. The metering type Venturi fertilizer injector comprises a fertilizer injector main body and a flowmeter; a threaded hole is designed and arranged at the throat of the water inlet end of the fertilizer injector main body; an adjustable bolt is arranged in the threaded hole; an adjusting valve is arranged at the lower end of the fertilizer injector main body and is connected with the flowmeter; and a valve rod is arranged in the adjusting valve. The metering type Venturi fertilizer injector has the advantages that the threaded hole is designed and arranged at the throat of the water inlet end of the fertilizer injector main body, and the amount of water flowing in the throat can be adjusted by adjusting the adjusting bolt leftward and rightward, so that the purpose of adjusting the generated negative pressure (suction force) can be achieved; meanwhile, a thread adjusting direction is designed and arranged on the fertilizer injector main body, so that the fertilizer injector is used by customers conveniently and practically; besides, the adjusting bolt is designed and arranged at the upper end of a connecting part of the metering type Venturi fertilizer injector provided by the utility model, serves as an effective complement for the bolt on the fertilizer injector main body, and complements and coordinates with the bolt; and the flowmeter is connected to the lower end of the connecting part of the metering type Venturi fertilizer injector.
Description
Technical field
The utility model relates to a kind of fertilizer injector, is specifically related to a kind of metering-type venturi fertilizer injector.
Background technology
At present, irrigation system commonly used is both at home and abroad annotated fertile form the fertile pump of differential fertilizer spreading tank, Development of Venturi Fertilizer Applicator, hydro powered fertilizing pump (for example membrane pump, piston pump etc.) and electronic notes etc., and these fertilizer-injecting devices all need be injected into solution in the pipeline of sealing by means of external impetus or the pressure vessel that seals by the outside.Yet these fertilizer apparatuses are kept away the fertilising inequality that unavoidably produces in the fertilising process, can't regulate fertilizer-injecting quantity, are not easy to defectives such as control.
The utility model content
It is even that the purpose of this utility model provides a kind of fertilizer-injecting quantity, can freely control simultaneously and annotate fertile concentration, breaks away from other big auxiliary equipment and metering-type venturi fertilizer injector simple to operate.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:
The metering-type venturi fertilizer injector, comprise: fertilizer injector main body, flowmeter, the water inlet throat design of described fertilizer injector main body has screwed hole, an adjustable bolt is arranged in the described screwed hole, described fertilizer injector main body lower end also is provided with a control valve, described control valve is connected with flowmeter, is provided with a valve rod in the described control valve.The utility model has screwed hole in the design of fertilizer injector main body water inlet throat, control the size of throat's inflow by the left and right adjusting bolt, thereby realize the size of institute's negative pressure that produces (suction), designing on the while fertilizer injector main body has the threaded adjusting direction, and it is convenient and practical to be convenient to the client; The attaching parts upper end design of the utility model metering-type venturi fertilizer injector has the adjusting bolt, is the effectively additional of bolt on the fertile main body of notes, and its pass is to replenish coordination, lower end connection traffic meter mutually.
Described fertilizer injector body interior structure is by the design of computational fluid dynamics (CFD) technical modelling.
In sum, the utlity model has following beneficial effect:
1, the utility model has screwed hole in the design of fertilizer injector main body water inlet throat, control the size of throat's inflow by the left and right adjusting bolt, thereby realize the size of institute's negative pressure that produces (suction), designing on the while fertilizer injector main body has the threaded adjusting direction, and it is convenient and practical to be convenient to the client;
2, the design of the attaching parts of the utility model metering-type venturi fertilizer injector upper end has the adjusting bolt, is the effectively additional of bolt on the fertile main body of notes, and its pass is to replenish coordination, lower end connection traffic meter mutually.
Description of drawings
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is the cutaway view of control valve of the present utility model and flowmeter part;
Among the figure, 1 is the fertilizer injector main body, and 2 is flowmeter, and 3 is control valve, and 4 is valve rod, and 5 is bolt.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, but as long as all are subjected to the protection of Patent Law in claim scope of the present utility model.
Embodiment 1: metering-type venturi fertilizer injector as shown in Figure 1 and Figure 2, comprise: fertilizer injector main body 1, flowmeter 2, the water inlet throat design of fertilizer injector main body 1 has screwed hole, an adjustable bolt 5 is arranged in the screwed hole, fertilizer injector main body 1 lower end also is provided with a control valve 3, control valve 3 is connected with flowmeter 2, is provided with a valve rod 4 in the control valve 3.
Fertilizer injector main body 1 interior is by the design of computational fluid dynamics (CFD) technical modelling.
Design has screwed hole on the present embodiment metering-type venturi fertilizer injector, by left and right sides bolt 5, control water inlet throat dimension size, be the inflow size, realize better inhaling the fertilizer efficiency fruit, by left and right adjusting valve rod 4, make and control fertilizer-injecting quantity, promptly control fertilizer concentration, the end of flowmeter 2 connects the PVC flexible pipe, connects non-return valve and filter.
