Leakage-proof device for pressure water pipe lead-out line interface

Abstract

The invention provides a leakage-proof device for a pressure water pipe lead-out line interface, which belongs to the fields of fluid equipment design, manufacture and technical application. The leakage-proof device for the pressure water pipe lead-out line interface comprises a hollow sleeve, a rubber sealing element, a threading pipe core and a stress nut, wherein the hollow sleeve is welded ona submersible pump power line lead-out interface of a pressure water pipe; the rubber sealing element is pressed in the hollow sleeve through the threading pipe core; the threading pipe core is fixedon the hollow sleeve through the stress nut; a pressure water pipe threading hole is formed on the position opposite to the position where the pressure water pipe is welded with the hollow sleeve; a sealing element threading hole, which is matched with the pressure water pipe threading hole and through which the submersible pump power line can be led out of the pressure water pipe, is formed on the rubber sealing element; and a threading pipe core outlet hole matched with the sealing element threading hole is formed on the threading pipe core. The leakage-proof device for the pressure water pipe lead-out line interface has good sealing effect, is convenient to assemble and disassemble, and can realize immediate sealing tight regulation under the working condition of a water pump.

Description

technical field [0001] The invention relates to a leak-proof device, in particular to a leak-proof device used for the lead-out line interface of a pressure water pipe, wherein the lead-out line refers to the power line of a submersible pump. It belongs to the field of design, manufacture and technical application of fluid equipment. Background technique [0002] Water - is the source of human life. "Improving the quality of drinking water and ensuring the safety of water quality" is a major event related to the health and life safety of the people, and the research and development of environmentally friendly water equipment has become a top priority. The pipe network superimposed water supply equipment that makes full use of the pressure of the municipal water supply pipe network has the advantages of energy saving, power saving, hygienic and safe water supply, and small footprint, and is being used more and more. In order to achieve silence, the pipe network superimposed...
