Plastic pipe well integrated device capable of preventing leakage

Abstract

The invention relates to a plastic pipe well, in particular to a plastic pipe well integrated device capable of preventing leakage. The flange plates are arranged at the two ends of the pipe body and used for combining and connecting the pipe body, a leakage-proof mechanism is arranged outside the pipe body, the leakage-proof mechanism comprises a self-adjusting leakage-proof device, and the self-adjusting leakage-proof device comprises an upper leakage-proof pipe and a lower leakage-proof pipe. According to the sealing device, water flows into the cavity on the right side of the sealing ring through the pressure pipe, hydraulic force generated by flowing substances in the cavity on the right side extrudes the sealing ring at the moment, the sealing ring moves towards the leakage position till the leakage position is sealed, hydraulic pressure in the pressure pipe and the cavities is balanced at the moment, the sealing ring cannot move, and the leakage position is sealed; in addition, the upper leakage-proof pipe and the lower leakage-proof pipe of the pipe well are integrally formed with the pipe body, so that the installation difficulty is reduced.

Description

technical field [0001] The invention relates to a plastic tube well, in particular to a plastic tube well integrated device that can prevent leakage. Background technique [0002] The tube well is composed of wellhead, well wall tube, water filter tube and sand settling tube; the periphery of the wellhead of the tube well is sealed with impermeable material, the crushed stone is laid around the wellhead of the artesian well and concrete is poured, and the well wall can be made of steel pipe, cast iron pipe, reinforced concrete Pipes or plastic pipes, etc.; steel pipes are suitable for a wide range of well depths; cast iron pipes are generally suitable for well depths not exceeding 250 meters; reinforced concrete pipes are generally used for well depths of 200 to 300 meters; plastic pipe wells can be used for well depths of more than 200 meters. [0003] However, plastic tube wells are poorly sealed during use, and are prone to leaks. It is very dangerous when some flammable ...

Problems solved by technology

[0003] However, plastic tube wells have poor sealing performance during use and are prone to leakage. It is very dangerous when used with some flammable and explosive flowing substances. Once leakage will cause huge losses, many plastic tube wells need additional anti-leakage installations device, but it is very cumbersome to install and cannot be integrally formed
