A Venturi-type fertilizer suction device. The existing Venturi-type fertilizer suction device has a single specification and cannot be matched with liquid adders of various calibers. The technical solution of the utility model to solve the above problems is: the Venturi-type fertilizer suction device The device includes the water inlet main pipe. The water inlet main pipe is composed of a shrinkage pipe, a throat pipe and a diffusion pipe. The shrinkage pipe is threadedly connected with the throat pipe, and the throat pipe is threaded with the diffuser pipe. The middle part of the throat is the throat section of the water inlet main pipe. The inner diameter from the water inlet of the shrink tube to the beginning of the throat section gradually changes from large to small, and the inner diameter from the end of the throat section to the outlet of the diffuser pipe gradually changes from small to large. The throat section One side of the machine is provided with a fertilizer suction port, and the fertilizer suction port is connected with a fertilizer suction side pipe. The utility model has the beneficial effects: threaded connection, convenient installation and disassembly; low cost, compact structure, light and practical; suitable for all water-saving irrigation equipment, and fertilizer and water can be irrigated at the same time, which improves the utilization efficiency of fertilizers and pesticides.
Description
Technical field
The utility model relates to the irrigation installation field, relates in particular to the fertile device of a kind of suction.
Background technology
Inhale fertile device and in irrigation system, be in space of top prominence, present venturi is inhaled fertile device and is only second to the fertile device of differential suction at China's application quantity, but it is plastic products that existing venturi type is inhaled fertile device, utilize mold injection to form, different bores need be made different moulds, and cost is too big, only be fit to produce in batches, so that it is single that existing venturi type is inhaled fertile device specification, can't with the charger coupling of various bores, seriously limited its scope of application.
Summary of the invention
The purpose of this utility model provides a kind of venturi type and inhales fertile device, and having solved existing venturi type, to inhale fertile device specification single, can't with the problem of the charger coupling of multiple bore.
The technical scheme that realizes above-mentioned purpose is:
A kind of venturi type is inhaled fertile device, comprise that into water is responsible for, water inlet is responsible for by collapsible tube, trunnion, anemostat constitutes, collapsible tube is threaded with trunnion, trunnion is threaded with anemostat, the water inlet that the water inlet of collapsible tube is responsible for for water inlet, the venturi section that the middle part of trunnion is responsible for for water inlet, the water inlet of collapsible tube is to the descending gradual change of the internal diameter at the top of venturi section, the end of venturi section is to the ascending gradual change of the internal diameter of the delivery port of anemostat, one side of venturi section is provided with inhales fertile mouthful, and a suction fertilizer mouthful place is connected with inhales fertile side pipe, and the internal diameter of inhaling fertile side pipe advances the fertilizer mouth by it and plays descending gradual change.
Venturi type is inhaled fertile device and is installed on the water supply line, under the certain situation of flow, flow velocity increases current during by the venturi section, pressure reduces, and utilizes the low pressure of venturi section to make the liquid in the fertilizer tank enter into water and be responsible for through inhaling fertile side pipe, finally flows into main water supply pipe.
The utlity model has following beneficial effect:
Be threaded, make things convenient for installing/dismounting; Cost is low, and compact conformation is light and handy practical; Suitable all water-saving irrigation devices, and rich water has improved the utilization ratio of fertilizer and agricultural chemicals with irritating.
Description of drawings:
Fig. 1 is the cutaway view that the described venturi type of the utility model embodiment is inhaled fertile device;
Among the figure:
1, water inlet is responsible for; 2, inhale fertile side pipe; 3, collapsible tube; 4, trunnion; 5, anemostat; 6, venturi section; 7, inhale fertile mouthful.
Embodiment
Embodiment:
The described venturi type of present embodiment is inhaled fertile device, comprise the water inlet person in charge 1 who adopts the metal material making and inhale fertile side pipe 2, water inlet is responsible for by collapsible tube 3, trunnion 4, anemostat 5 constitutes, collapsible tube 3 is threaded with trunnion 4, trunnion 4 is threaded with anemostat 5, the water inlet of collapsible tube 2 is responsible for 1 water inlet for water inlet, 1 venturi section 6 is responsible at the middle part of trunnion 5 for water inlet, the water inlet of collapsible tube 3 is to the descending gradual change of the internal diameter at the top of venturi section 6, the end of venturi section 6 is to the ascending gradual change of the internal diameter of the delivery port of anemostat 5, one side of venturi section 6 is provided with inhales fertile mouthful 7, fertile mouthful 7 places of suction have been threaded and have inhaled fertile side pipe 2, and the internal diameter of inhaling fertile side pipe 2 advances fertile mouth by it and plays descending gradual change.
Claims (2)
1. a venturi type is inhaled fertile device, it is characterized in that: comprise that into water is responsible for, water inlet is responsible for and is made of collapsible tube, trunnion, anemostat, collapsible tube is threaded with trunnion, trunnion is threaded with anemostat, the water inlet that the water inlet of collapsible tube is responsible for for water inlet, the venturi section that the middle part of trunnion is responsible for for water inlet, the collapsible tube water inlet is to the descending gradual change of internal diameter at venturi section top, venturi section end is to the ascending gradual change of the internal diameter of anemostat delivery port, one side of venturi section is provided with inhales fertile mouthful, and fertile mouthful of place of suction is connected with inhales fertile side pipe.
