Membrane element pipe fitting, tool thereof, spiral wound water-saving membrane element, and water purifier

Abstract

The invention discloses a membrane element pipe fitting, a tool thereof, a spiral wound water-saving membrane element, and a water purifier. The tool of the membrane element pipe fitting comprises connecting pieces, insert parts, first fasteners and second fasteners, the connecting pieces are arranged at the first ends of pure water tubes, and the connecting pieces are provided with insert slots;the insert parts are adapted to the insert slots and are arranged at the first ends of wastewater tubes, and the wastewater tubes are arranged on the side surfaces of the pure water tubes side by sidealong the extending longitudinal direction of the pure water tubes; the first fasteners are arranged at the second ends of the pure water tubes; and the second fasteners are in close fit with the first fasteners and are arranged at the second ends of the wastewater tubes, and the size of the second fasteners is more than the size of the insert slots to prevent the second fasteners from being inserted into the insert slots. The assembling reliability of the membrane element pipe fitting is improved.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a membrane element pipe fitting and its tooling, a spiral-wound water-saving membrane element and a water purifier. Background technique [0002] Water purifier is a kind of water treatment equipment used to purify water quality. The spiral-wound water-saving membrane element is a common element in water purifier, and generally has a high recovery rate and a long membrane life. Spiral-wound water-saving membrane elements include membrane element pipe fittings and water-saving diaphragm groups wound on the membrane element pipe fittings, wherein the membrane element pipe fittings include pure water pipes and waste water pipes, and the pure water and waste water are separated from the pure water pipes and waste water pipes respectively. The flow in the tube follows the set direction. However, since the two ends of the tooling of the membrane element pipe fittings are ba...

AI Technical Summary

Problems solved by technology

[0003] The main purpose of the present invention is to propose a tooling for membrane element pipe fittings, which aims to solve the problem that the two ends of the waste water pipe are easily reversed during the above assembly process, and improve the assembly reliability of the membrane element pipe fittings.
