Prefabricated building same-layer drainage pipe fitting

Abstract

The invention discloses a prefabricated building same-layer drainage pipe fitting which comprises a stand pipe joint and a transverse pipe joint; the stand pipe joint is in up-down communicating; thetransverse pipe joint is arranged on one side of the stand pipe joint and communicates with the stand pipe joint; the transverse pipe joint is formed by a water seal groove, a water seal baffle plate,a cross pipe drainage inlet and a branch pipe interface; the water seal groove is closed with the outer wall of the stand pipe joint and communicates with the inner wall of the stand pipe joint; thelower end of the water seal groove is closed; the side wall, close to the stand pipe joint, of the upper end of the water seal groove is provided with a through hole; a length of a transverse longestpart of the through hole is larger than a length of a vertical longest part of the through hole; and a length of a transverse longest part of a communication hole is larger than a length of a verticallongest part of the communication hole. The prefabricated building same-layer drainage pipe fitting has the advantages that by providing the prefabricated building same-layer drainage pipe fitting, water seals for connecting all drainage devices can not be dried easily, the drainage safety and the drainage smoothness can be both improved, a pipeline is convenient to change, disassemble and mountat the same time, the use amount of drainage transverse branch pipes can be saved, water accumulation can be avoided in a toilet for any reason, and peculiar smell can not be easily produced in toilet.

Description

technical field [0001] The invention relates to a same-layer drainage pipe fitting, in particular to an assembled building same-layer drainage pipe fitting. Background technique [0002] At present, the laying of drainage pipes on the same floor in prefabricated buildings requires more water traps under each drainage appliance. The water traps for infrequently used appliances are easy to dry up, and the toilets are prone to odors. Although some pipeline layouts adopt centralized water sealing methods , but the centralized water seal drainage channel is narrow, which is likely to cause unsmooth drainage. What's more, some product structures make the drainage in the standpipe flow back into the water seal, resulting in reduced drainage safety, and toilets in prefabricated buildings often use When the water supply and drainage pipes in the bathroom are aging or there are sudden accidents such as water leakage, the accumulated water in the downboard cannot be safely discharged f...
