Water supply and drainage tail pipe with anti-corrosion function

Abstract

The invention discloses a water supply and drainage tail pipe with an anti-corrosion function. The water supply and drainage tail pipe comprises a water drainage head, a thread body and a nameplate. Afirst hexagonal stud and a second hexagonal stud are arranged at the two ends of a connecting seat. Two segments of grooves are formed in the middle position of a rod of the connecting seat. The nameplate is pasted to the middle position of the rod of the connecting seat. A thread hole is formed in the circle center of the first hexagonal stud. An anti-falling ring is arranged at the bottom of the second hexagonal stud. A corrosion-resisting hose is mounted on the first hexagonal stud. The water drainage head is mounted at the other end of the corrosion-resisting hose. A lower fastening nut is arranged on the outer wall of the water drainage head. According to the water supply and drainage tail pipe, the corrosion-resisting hose and the connecting seat are arranged to be of a separable structure, when one part in two parts is damaged, the other part can be directly replaced easily, and the maintenance simplification of the parts is improved; the service life of the water supply and drainage tail pipe can be prolonged easily; and the practicality of the water supply and drainage tail pipe can be improved.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage equipment, in particular to a water supply and drainage tailpipe with anti-corrosion function. Background technique [0002] Currently used water supply and drainage pipes (including industrial and civil) basically include steel pipes, galvanized pipes, pure plastic pipes (including PVC, PP, PPR, PE, etc.), cast iron pipes, cement pipes and composite pipes, rubber-lined pipes and spray pipes, etc. wait. However, galvanized pipes and cement pipes are basically not allowed to be used now. Steel pipes are basically only used in special occasions such as high temperature and high pressure due to cost and anti-corrosion reasons. Cast iron pipes used as drainage are not low in cost but have the same leakage rate as cement pipes. Pollution of the environment is also reduced. Rubber-lined and spray-coated pipes have been rarely seen in the past ten years due to process and cost reasons....

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, plastic pipes or steel-plastic composite pipes are mostly used as industrial and civil water supply and drainage pipes. However, the existing water supply and drainage pipes do not have any structure at the end of the pipe. Throw the mouth of the pipe underground to let the water flow out. The pipe with this structure can still meet the normal use when draining water, but when water is supplied, sometimes it is necessary to control the water flow at the mouth of the pipe. At this time, the water supply and drainage pipe with this structure cannot meet this requirement
