Abstract
The utility model provides an anti -drip valve mechanism, including inside water supply connector and the water connectors who forms flow channel, water supply connector and water connectors threaded connection, inside is equipped with the cylindrical cavity that is linked together with flow channel, internal diameter through being greater than flow channel in the cavity, the coming of cavity and flow channel is equipped with separable spherical case by flow channel to the junction, and the other end of spherical valve and cavity is connected with compression state's spring. The utility model discloses simple structure light in weight is fit for using on plant protection unmanned aerial vehicle, and the antidrip performance is good, can adjust low in production cost to spraying pressure through regulating spring is convenient.
Description
Technical field
The utility model relates to field of plant protection machine, is specifically related to a kind of anti-dripping valve structure.
Background technique
At present, equipment for plant protection in the process of spraying insecticide, its special hanger-rod nozzle; after having sprayed, in shower nozzle, do not reach vacuum state, due to draught head; agricultural chemicals in shower nozzle more or less can water clock out, cause the poisoning of agricultural chemicals to crop and the pollution to soil.High to the requirement of weight on plant protection aircraft, need to reduce deadweight as much as possible, increase explosive load.
Summary of the invention
The utility model, for solving liquid drip leakage, provides the simple quality of a kind of structure light, the anti-dripping valve mechanism that leakage-proof performance is good.
The utility model realizes by the following technical solutions, anti-dripping valve mechanism, comprise the inner water supply connector and the water output connector that form liquid chunnel, described water supply connector is threaded with water output connector, inside is provided with the cylindrical cavity be connected with liquid chunnel, through being greater than the internal diameter of liquid chunnel in cavity, the spherical valve core being provided with separable cut-off liquid chunnel to joint of cavity and liquid chunnel, the other end of spherical valve and cavity is connected with the spring of compressive state.
For ease of fixing, the cross section of described spring is taper, and end is equal with the internal diameter of cavity.
For further sealing, the joint of described water supply connector and water output connector is provided with O RunddichtringO.
Usefulness of the present utility model is, structure is simply lightweight, is adapted at plant protection unmanned plane uses, and leakage-proof performance is good, and can regulate spray pressure by Regulation spring is convenient, cost of production is low.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
1. water supply connectors, 2. spherical valve core, 3. spring, 4. seal ring, 5. water output connector in figure.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises water supply connector 1 and water output connector 5, both are connected by the mode of internal and external threads, inner hollow-core construction forms liquid chunnel, the middle part being positioned at liquid chunnel is provided with the cavity structure that internal diameter is greater than liquid chunnel, is provided with spherical valve core 2, the round nose of spherical valve core 2 and being connected to the separable cut-off of mouth of liquid chunnel at cavity inside, the rear end linking springs 3 of spherical valve core 2, spring 3 contacts with the other end of cavity and connects.
In order to improve the stability of spherical valve core 2, spring 3 is equal with internal diameter with the contact segment diameter of cavity.The end be connected with water output connector 5 in water supply connector 1 is provided with O RunddichtringO 4, seals further to cavity.
The utility model is when specifically using, spherical valve core can under the pressure of the spring by liquid chunnel blocking cut-off, liquid can flow at liquid chunnel through pressurization, when flowing to the spherical valve core in cavity owing to there is certain pressure, spherical valve core can be backed down, flow out through spring, ensure to flow normally.When breaking down underpressure or initiatively shutting down, the underpressure of liquid, will keep the state blocked, liquid cannot flow out, and plays drip-proof effect.
