Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0025] see Figure 1-4 , a quick exhaust valve for agricultural irrigation pipelines, comprising an exhaust device 1 and a connecting device 2, the bottom of the exhaust device 1 is fixedly installed with the connecting device 2.
[0026] The exhaust device 1 includes a valve body 101, the outer wall of the bottom end of the valve body 101 is connected with an air-water inlet pipe 102, and the inside of the air-water inlet pipe 102 is equipped with a floating body 103, and the surface of the floating body 103 is provided with expanded polytetrafluoroethylene. coating, and the floating body 103 is attached to the inner wall of the air-water inlet pipe 102, and the expanded polytetrafluoroethylene material has good waterproof and windproof properties, excellent air permeability,...

The invention relates to the technical field of agricultural irrigation, and discloses an agricultural irrigation pipeline rapid exhaust valve. The rapid exhaust valve of the agricultural irrigation pipeline comprises an exhaust device and a connecting device, wherein a connecting device is fixedly arranged at the bottom of the exhaust device, the exhaust device comprises a valve body, a gas-waterinlet pipe is communicated with the outer wall of the bottom end of the valve body, a floating body is movably arranged in the gas-water inlet pipe, and a pressing plate is fixedly arranged at the top end of the floating body. According to the rapid exhaust valve of the agricultural irrigation pipeline, due to the arrangement of the buffer valve, the impact caused by excessive water pressure canbe avoided, the floating body is damaged, the two exhaust pipes are arranged on the valve body, and the exhaust efficiency is improved. Due to the arrangement of the supporting rod, the floating bodyis kept vertical all the time, and the stability of the floating body during up-and-down movement is improved; the sliding rod, the sliding block and the connecting rod are arranged, so that the stability of left and right movement of the spherical piston is improved; due to the arrangement of the limiting block, the floating body is prevented from being separated from the gas-water inlet pipe dueto overhigh water level.
Description
technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a quick exhaust valve for agricultural irrigation pipelines. Background technique [0002] Agricultural irrigation mainly refers to the irrigation of agricultural farming areas. Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation and micro-irrigation. The pipeline of the agricultural irrigation system is a closed pipeline. In some parts of the pipeline stroke, due to the difference in pipeline shape and water level, some pipeline nodes will accumulate a small amount or a large amount of air during the drainage process. In severe cases, a vacuum will be formed, resulting in pipeline drainage. Bad situation. [0003] In the prior art, the above-mentioned problems are usually solved by installing an exhaust valve on the highest point of the system pipeline. However, the exhaust efficiency of t...
