Description

Technical Field

[0001] The utility model relates to the technical field of drippers, in particular to a compensating pressure dripper. Background Art

[0002] The dripper is an energy dissipation and water outlet facility of the drip irrigation system. Its function is to eliminate the residual energy of the pressure water flow in the capillary tube, so that the water flows into the soil drop by drop from the outlet evenly and slowly. The dripper can be divided into long-flow dripper, orifice dripper and microporous capillary tube according to its energy dissipation characteristics. However, the traditional dripper has a relatively simple structure and has the following shortcomings when used:

[0003] 1. When laying pipes, it is easy for them to be at different heights, which causes the drippers at different heights to be under different pressures, resulting in different fluid dripping speeds.

[0004] 2. The dripper has poor sealing performance and is prone to fluid leakage.

[0005] Therefore, we propose a compensatory pressure dripper. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that pipelines are easily laid at different heights, so that drippers at different heights are subjected to different pressures, resulting in different fluid dripping speeds, poor sealing of the drippers, and easy fluid leakage, and a compensating pressure dripper is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A compensatory pressure dripper, comprising:

[0009] A dripper tube, wherein a drip nozzle is integrally formed at the top of the dripper tube, a first annular groove is provided on the inner wall of the top of the dripper tube, an annular sealing ring is provided in the first annular groove, a second annular groove is provided on the circumferential inner wall of the dripper tube, and an internal thread is provided in the second annular groove;

[0010] The mounting tube is arranged in the dripper tube, the outer wall of the mounting tube is provided with an external thread matched with the internal thread, a cavity is provided inside the mounting tube, the cavity is arranged in a stepped shape from top to bottom, a connecting tube is integrally formed at the bottom of the mounting tube, a buffer block is integrally formed on the inner wall of the connecting tube, the cavity is respectively connected with the drip nozzle and the connecting tube, and a positioning ring is integrally formed on the outer wall of the mounting tube, and the positioning ring is in contact with the inner wall of the dripper tube.

[0011] In a possible design, an outer wall of the positioning ring is provided with an annular inclined surface.

[0012] In a possible design, a plurality of buffer grooves are provided at the bottom of the mounting tube.

[0013] In a possible design, a plurality of first reinforcing ribs are provided between the dripper tube and the drip nozzle.

[0014] In a possible design, a plurality of second reinforcing ribs are provided on the surface of the dripper tube.

[0015] In a possible design, a third reinforcing rib is provided at the bottom end of the dripper tube.

[0016] In the present application, when in use, the fluid enters from the connecting tube, and under the buffering of the buffer block, the fluid speed is reduced and enters the cavity, the fluid diffuses in the cavity, further consuming the energy of the fluid, and finally the fluid drips from the drip nozzle to achieve irrigation.

[0017] Beneficial effects:

[0018] In the utility model, the compensating pressure dripper is provided with a cavity and a buffer hole. The buffer hole can buffer the fluid and reduce the speed of the fluid. At the same time, the fluid diffuses after entering the cavity, further consuming the energy of the fluid, thereby reducing the difference in dripping speed of fluids at different heights, so that irrigation is relatively uniform.

[0019] In the utility model, the compensating pressure dripper can position the installation pipe by setting the positioning ring and the sealing ring, so as to avoid the structure of the installation pipe being offset after the fluid impact, so that the installation pipe is more stable and can be in close contact with the sealing ring, thereby ensuring the sealing of the structure;

[0020] In the utility model, the fluid can be buffered and diffused, and the difference in dripping speed of fluids at different heights can be reduced, so that irrigation is relatively uniform. The installation pipe can also be positioned to avoid displacement of the installation pipe due to force, and it can be in close contact with the sealing ring to ensure the sealing of the structure.
