Composite novel water taking device for water well

Abstract

The invention relates to the technical field of water taking tools for pressurized water wells, and discloses a composite novel water taking device for a water well. The device comprises a cylinder pipe, a water pumping pipe, a check valve and a control rod, a movable pipe body capable of moving up and down is arranged in an inner cavity of the cylinder pipe, up-down movement of the movable pipe body is controlled by the control rod, a sealing air bag is arranged on the outer surface of the movable pipe body, and the outer side of the sealing air bag bulges up in the upward moving process of the movable pipe body and is in fit with the inner wall of the cylinder pipe. According to the composite novel water taking device for the water well, a piston is replaced by the movable pipe body andthe sealing air bag, when the movable pipe body moves upwards to take water, the sealing air bag bulges up to be in fit with the inner wall of the cylinder pipe, water or air above and below the movable pipe body in the inner cavity of the cylinder pipe is separated, the water above the movable pipe body is taken out, meanwhile, the volume of vacuumizing below the movable pipe body in the inner cavity of the cylinder pipe is kept unchanged, and the accuracy of each water pumping amount is ensured. The water taking efficiency is effectively improved compared with existing products.

Description

technical field [0001] The invention relates to the field of water-taking tools for pressurized wells, in particular to a novel composite water well pressure-taking device. Background technique [0002] Water is an inseparable substance in people's lives. Although the popularity of tap water has facilitated people's domestic water use, in some remote mountainous areas and rural areas, wells are still used for daily life. Compared with tap water, well water has Eliminates heat and detoxification, and helps to urinate red hot. Regular drinking is good for physical and mental health. [0003] The well water is often used in the water well pressure taking device (that is, the water well pressure device). When the water is taken, the piston is moved up and down in the cylinder by controlling the piston and the cylinder. The principle of air pressure is used to pump the well water out. However, since the cylinder of the water well pressure-taking device is made of metal, the pist...

Problems solved by technology

[0003] The well water is often used in the water well pressure taking device (that is, the water well pressure device). When the water is taken, the piston is moved up and down in the cylinder by controlling the piston and the cylinder. The principle of air pressure is used to pump the well water out. However, since the cylinder of the water well pressure-taking device is made of metal, the piston will be worn after moving up and down for a long time in the cylinder, which will increase the gap between the piston and the inner wall of the cylinder. During the upward movement of the piston, part of the water above the piston will be left from the gap, so that the vacuum volume under the piston in the cylinder is reduced, so the amount of water extracted each time is reduced, resulting in a decrease in the efficiency of water intake
