Abstract
The utility model relates to a screwed connection plug type pressure compensating emitter, which aims to overcome the defects that the existing emitter with the compensating function is of a high-end product, and a flexible diaphragm additionally arranged at a water outlet has high requirements for elasticity and precision of material and high price. The screwed connection plug pressure compensating emitter comprises an emitter body, and is characterized in that the emitter body consists of an upper part and a lower part which are connected by screw threads, and a plug is arranged in the intracavity of the emitter; and convex-concave layers are arranged on the outer wall of the plug, and the pipe wall at the upper part of the emitter is provided with screw threads for connecting with a water diversion pipe. The emitter consists of two parts, and has convenient disassembly and replacement; when the water pressure in the water diversion pipe is increased, the plug is extruded, so that water flows out of a gap generated between the convex-concave layers arranged on the outer wall of the plug and the inner wall of the emitter; and when the water pressure in the water diversion pipe is reduced, the plug returns to the original position, so that the water flows out of the gap, thereby ensuring the water outlet amount is approximately equal whether the water pressure is high or low.
Description
Technical field
The utility model relates to the water dropper on a kind of irrigation pipe, is specifically related to a kind of nipple stopper pressure compensation water dropper.
Technical background
Drip irrigation is one of typical application form of micro irrigation technology, is meant that water slowly goes out near the soil of stream infiltrating by the water dropper on the buried pipe, relends to help capillarity or gravity effect that moisture diffusion is made for thing to whole root zone to absorb.Less to the soil texture disturbance in the process owing to pour water, help keeping the root of the crop layer penetrating environmental condition of loosening, and can reduce native face evaporation loss, so drip irrigation technique has tangible water-saving and yield-increasing benefit.The normal problem that occurs of drip irrigation mainly is the even inadequately along the journey water yield of it, and local water yield general far away apart from the water source is less.In order to ensure the amount of the dripping basically identical in the unit interval of each water dropper under the different water droppers, people develop the focus that multi-form compensation water dropper becomes this field at present.The water dropper that wherein adds a flexible sheet on the water dropper delivery port is its high-end product, and this product requirement material property is good, making precision height, so price is very high, popularity is restricted in production application.Have superperformance and products are at a low price called in agricultural production more.When realizing that promptly hydraulic pressure is big, though water flow velocity is fast, runner water inlet sectional area is little; Realize hydraulic pressure hour, though water flow velocity is slow, but runner water inlet sectional area is relatively large, so just can guarantee effectively that the drip total amount of each water dropper in the unit interval under different water droppers is basic identical, thereby effectively realize the compensation of pressure and flow, but this technology also exists such problem: promptly after water pressure was increased to a certain degree, the sectional area of water channel water inlet was very little, water dropper so just takes place easily stop up.
The utility model content
The purpose of this utility model is to provide a kind of nipple stopper pressure compensation water dropper, in the time of can guaranteeing that water arrives at a distance, and the height of hydraulic pressure no matter, water yield is near equating.
For achieving the above object the technical scheme that the utility model is taked:
The utility model comprises the water dropper body, and its special character is: described water dropper body is made up of water dropper top and water dropper bottom, between the two by being threaded; Described water dropper inner chamber is provided with stopper, and the outer wall of stopper vertically or in the shape of a spiral shape setting is provided with buckle layer; Described water dropper top tube wall is provided with screw thread and is connected with aqueduct.
Above-mentioned buckle layer adopts elastic caoutchouc.
The buckle layer of above-mentioned vertical setting evenly is arranged on the outer wall of stopper.
The jut of above-mentioned buckle layer is a triangle.
The beneficial effects of the utility model:
The utility model is connected with aqueduct, when aqueduct hydraulic pressure increased, stopper was extruded, and water is provided with the gap outflow of the inwall generation of buckle layer and water dropper by the outer wall of stopper, when aqueduct hydraulic pressure reduces, stopper returns initial position, and water flows out from the gap, thereby no matter guarantees the hydraulic pressure height, water yield is near equating, employing is threaded, and its good airproof performance can not produce the infiltration phenomenon.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is for vertically being provided with the vertical view of the stopper of buckle layer.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1～2, the utility model comprises the water dropper body, and the water dropper inner chamber is provided with stopper 1, and the outer wall of stopper 1 is provided with buckle layer 2.
The water dropper body is made up of water dropper top 4 and water dropper bottom 5, and by being threaded, stopper 1 is unsettled in water dropper inside between the two, and moving of stopper 1 can be limited in water dropper top 4.
The tube wall on water dropper top 4 is provided with screw thread and is connected with aqueduct 3, and employing is threaded, and its good airproof performance can not produce the infiltration phenomenon, and employing is threaded the water dropper convenient disassembly.
The utility model is connected with aqueduct 3, when aqueduct 3 hydraulic pressure increase, stopper 1 is extruded, water is provided with the gap outflow of the inwall generation of buckle layer 2 and water dropper by the outer wall of stopper 1, when aqueduct 3 hydraulic pressure reduced, stopper 1 returned initial position, and water flows out from the gap, thereby no matter guarantee the hydraulic pressure height, water yield is near equating.
