Description

Technical Field

[0001] This utility model belongs to the field of irrigation drip valve technology, specifically a water-saving irrigation drip valve. Background Technology

[0002] Drip irrigation uses plastic pipes to deliver water to the roots of crops through orifices or drippers on capillary tubes with a diameter of about 10mm for localized irrigation. It is the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation. It can also be combined with fertilization to increase fertilizer efficiency by more than double. It is suitable for irrigation of fruit trees, vegetables, cash crops, and greenhouses. It can also be used for irrigation of field crops in arid and water-scarce areas. Its disadvantage is that the drippers are prone to scaling and clogging, so the water source should be strictly filtered.

[0003] Drip irrigation systems install valves on the main pipeline and drip irrigation branches to control the drip flow rate. Drip valves are located at the drip heads and can control each drip head individually. If drip irrigation water relies solely on the filtration of the water source, it cannot be thoroughly filtered and cleaned. Over time, this can cause the drip heads or drip valves to become clogged or scaled. Therefore, a water-saving irrigation drip valve is proposed here. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a water-saving irrigation drip valve, which effectively solves the problems of easy clogging, short maintenance cycle and high cost of use of existing drip valves.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-saving irrigation drip valve, comprising a connector, a support ring on the inner wall of the connector, a connecting ring at the upper end of the support ring, a filter screen at the lower end of the connecting ring, a connecting pipe at the middle of the lower end of the connector, a drip valve body at the periphery of the lower end of the connecting pipe, an adjusting knob rotatably connected to one side wall of the drip valve body, a sealing ring between the lower part of the connecting pipe and the drip valve body, and a filter cover inside the connecting pipe located below the filter screen.

[0006] Preferably, the support ring is formed on the inner wall of the connector, the lower end of the connecting ring overlaps with the upper end of the support ring, and the connecting ring can be separated from the support ring.

[0007] Preferably, the connecting ring is slidably connected to the inner wall of the connector, the filter bag is glued to the connecting ring, and the filter bag is slidably connected to the inner wall of the connecting ring, so that the filter bag can be removed from the connector through the connecting ring.

[0008] Preferably, the connecting pipe is formed in the middle of the lower end of the connector, the filter cover is inserted into the inner wall of the connecting pipe, the diameter of the filter cover is smaller than the inner diameter of the support ring, the filter cover can be removed from the connector, the filter screen and the filter cover can perform double filtration of the water flowing through the connector and the connecting pipe, making the water entering the drip valve body cleaner, making the drip valve body less prone to clogging and scaling, and greatly extending the maintenance cycle and service life of the drip valve body.

[0009] Preferably, the sealing ring is inserted into the connecting pipe, and the outer wall of the connecting pipe is threaded to the upper inner wall of the drip valve body.

[0010] Preferably, the sealing ring is pressed between the connecting pipe and the drip valve body, and the sealing ring overlaps with the inner wall of the drip valve body, so that the sealing ring can ensure the sealing between the connecting pipe and the drip valve body.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] In this water-saving irrigation drip valve, the filter bag and filter cover can perform double filtration of the water flowing through the connector and connecting pipe, making the water entering the drip valve body cleaner, preventing the drip valve body from clogging and scaling, and greatly extending the maintenance cycle and service life of the drip valve body; the structural design of the connecting ring, filter bag and filter cover allows the filter bag and filter cover to be easily removed after the connector is removed for cleaning or replacement, making maintenance very convenient.
