Description

Adjustable pressure compensation water dropper

Technical Field

The utility model relates to an irrigation equipment field specifically indicates a pressure compensation water dropper with adjustable.

Background

The development of water-saving agriculture is one of the main directions of modern agriculture, and drip irrigation is an advanced high-standard irrigation technology in water-saving irrigation. The drip irrigation is a drip irrigation mode of pressurizing and filtering water, delivering the water to a dripper through a low-pressure pipeline and dripping the water to the roots of crops in a drip mode, can save water and last, and is widely applied to fields, greenhouses, ecological gardens and urban landscaping. The existing pressure compensation dripper adjusts pressure by changing the flow area of the dripper, for example, an elastic diaphragm is adopted. When the water flow pressure is increased, the elastic membrane is extruded, the water outlet of the flow channel is reduced, and the water pressure is reduced, so that the outlet flow of the dripper is kept stable. However, in this solution, the position between the elastic membrane and the water outlet of the flow channel is fixed, so the adjustable pressure range is also fixed. When the water pressure exceeds the application range, the drippers need to be replaced, and the pressure compensation range cannot be adjusted.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome above difficulty, provide a pressure compensation water dropper with adjustable can carry out the artificial adjustment according to the water pressure size.

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a pressure compensation water dropper with adjustable, includes base and block, the base passes through threaded connection with the block, the tip of block is equipped with the inlet tube, be equipped with the washer in the block, the one end connection of keeping away from the inlet tube on the washer is equipped with the spring, the other end connection of spring is equipped with the rubber diaphragm, the one end of keeping away from the spring on the rubber diaphragm is equipped with spiral groove, the interior alternately dog that is equipped with of spiral groove, the tip of base is equipped with the outlet pipe.

As an improvement, one end of the water inlet pipe, which is far away from the base, is provided with a sleeving part.

As an improvement, the rubber diaphragm is arranged in the base.

As an improvement, the outer sides of the base and the cover cap are provided with anti-skid grains.

As an improvement, the inner side of the base is provided with an internal thread, the outer side of the cap is provided with an external thread, and the base is connected with the cap through the internal thread and the external thread.

The distance between base and the block is favorable to adjusting to the setting of external screw thread and internal thread. And the moving state of the baffle plate, the spring and the rubber diaphragm in the dripper cavity can be adjusted according to different water pressures.

Compared with the prior art, the utility model the advantage lie in: when water pressure is great, can make washer laminating block, rubber diaphragm laminating base through twisting by base and block, make the more even driping irrigation of dripper, the crossing dog in the spiral groove can reduce the speed of rivers, and then reduces water pressure, when water pressure is less, can enlarge the distance between base and the block, makes washer, spring and rubber diaphragm freely slide in the dripper cavity to this makes the continuous droping of rivers.
