Embodiment Construction

[0015] The present invention is specifically described below by embodiment and accompanying drawing:

[0016] Such as figure 1 As shown, the special one-way pipe connection bypass for buried drip irrigation of the present invention includes a water inlet half body 3, a backstop valve 8, and a water outlet half body 9; the water inlet half body 3 includes a booster block 4, a water inlet Barb 5, carrying platform 6; said water outlet half body 9 includes fixing platform 7, water outlet barb 10. The outer wall of the barb 5 of the water inlet wraps the rubber ring 2 to ensure a good seal between the outer wall of the water inlet and the pipeline.

[0017] The apron is made of EPDM rubber, which is resistant to aging and Acid and alkali resistance Strong chemical corrosion resistance and durability; the rubber ring is cylindrical and has grooves on the outer wall to fix and seal the bypass water inlet.

[0018] The water inlet half and the water outlet half are respectively i...

Abstract

The invention belongs to the technical field of micro-irrigation an provides a special one-way pipe connection bypass for buried drip irrigation and a manufacturing method. The special one-way pipe connection bypass comprises a water inflow half body, a reversing valve film and a water outflow half body. The water inflow half body comprises a boosting blocking part, a water inlet barb and a bearing platform. The water outflow half body comprises a fixing platform and a water outlet barb. By means of segmented injection molding of the water inflow half body and the water outflow half body, secondary injection molding is performed on the reversing valve film so that the special one-way pipe connection bypass for buried drip irrigation can be manufactured. The special one-way pipe connection bypass for buried drip irrigation is provided with the reversing valve film, and the special one-way pipe connection bypass for buried drip irrigation is manufactured through injection molding; and by cutting off backflow of water flow in a capillary tube, the inner and outer pressure difference of a water outlet of a water dripper can be reduced, the silt suction probability and the silt suction amount of the water outlet of the water dripper can be reduced, the siphon blockage probability of the water dripper can be reduced, the service life of the buried drip irrigation capillary tube can be prolonged, and the special one-way pipe connection bypass for buried drip irrigation has good industrial application prospects.

Description

technical field [0001] The invention belongs to the technical field of micro-irrigation, and in particular relates to a special one-way pipe connection bypass for buried drip irrigation and a preparation method thereof. Background technique [0002] In today's increasingly scarce water resources, water-saving irrigation, as an important way to save water in agriculture, is an inevitable trend in the development of resource-saving and environment-friendly modern agriculture. Buried drip irrigation is a new drip irrigation technology that has been widely promoted in the United States, Australia, Israel and other countries in recent years, that is, the drip irrigation capillary is laid below the cultivation layer, and the water and fertilizer needed by the crops are directly irrigated to the roots of the crops. This irrigation technology can directly supply water, fertilizer, air, etc. to the root system of crops, so it has a significant effect of saving water, promoting produc...
