Abstract

An inner spiral silencing standing pipe connector is a structural improvement of the existing spiral silencing standing pipe connector, solving the problem that the silencing performance of the former spiral silencing standing pipe connector is not perfect in use; an inner spiral silencing standing pipe connector is composed of a pipe body, a locking cover, a rubber ring and a branch pipe; the inner spiral silencing standing pipe connector can be changed to be three-way and four-way according to the requirements; in the pipe body, the outer wall is provided with a spiral convex tendon; the two ends of the pipe body are provided with the locking covers; the rubber rings are respectively arranged between the two locking covers and the pipe body; the side wall of the pipe body is provided with the branch pipes; the number of the branch pipes can be one or two according to the requirements; the branch pipe is provided with a locking cover; the rubber ring is arranged between the branch pipe and the locking cover; because the inner wall of the pipe body is provided with the spiral convex tendon, when the water flows down in a rotary way through the pipe body, the water flow from the upper end to the bottom of the standing pipe can fall down in a spiral way; the center of the pipe can form a complete air column, which improves the silencing performance of the water discharge system with the spiral standing pipe.

Description

Internal spiral noise reduction standpipe link

Technical field: the utility model relates to a kind of pipe joint, is a kind of internal spiral noise reduction standpipe link with threeway, four-way function specifically.

Background technique: at present, the helical silencing standpipe link that connects soil stack in the construction engineering is that inwall is a smooth surface, causes the helical current tomography of decline in the standpipe, and pipe center air post is destroyed, directly influences erasure effect.

Summary of the invention: in order to solve the problem of above-mentioned existence, the utility model provides a kind of internal spiral noise reduction standpipe link of good muffling effect; The purpose of this utility model is achieved through the following technical solutions: a kind of internal spiral noise reduction standpipe link, comprise body (1), be provided with tightening cover (2) on body (1) top, be provided with tightening cover (3) in body (1) bottom, between tightening cover (2,3) and body (1), be respectively equipped with cushion rubber (4,5), on the tube wall of body (1) side, be shaped on an arm (6), tightening cover (7) is housed on arm (6), be provided with cushion rubber (8) between arm (6) and the tightening cover (7), described body (1) inwall is shaped on helical convex tendon (12).

Be shaped on arm (9) on the tube wall of described body (1) another side, arm (9) is level 180 degree with arm (6), and tightening cover (10) is housed on arm (9), is provided with cushion rubber (11) between arm (9) and the tightening cover (10).

Described arm (9) is an angle of 90 degrees with arm (6).

The beneficial effects of the utility model: owing to be equipped with the helical convex tendon at inboard wall of tube body, when current when the body under the rotating flow, can keep from the current of upper end to the bottom of standpipe in the shape of a spiral shape fall, make pipe central authorities form air column, the perfect performance muffler of spiral stack drain system, have good erasure effect, the utility model internal spiral noise reduction standpipe link also can be made threeway, four-way as required, satisfies the needs that different pipelines connect.
