Abstract
The utility model relates to a drainage pipe backwater brake which comprises a brake main body, wherein the upper end of the main body is provided with an upper interface, a water seal inner sleeve and a lower interface are arranged on the inner lower part of the main body, and a clogging cover is connected to a decontamination opening of the main body. The utility model is characterized in that a guide sleeve is arranged on the inner middle part of the main body; the bottom of the guide sleeve is provided with a passage with a plurality of holes; a braking body is arranged in the guide sleeve and is sheathed with an awl bowl. When the utility model is used, the upper interface of the brake is connected with a sanitary ware, and the lower interface is connected with a drainage main pipe passage. When the main pipe passage is clogged and water returns, the upper interface can be automatically closed by using the pressure of returned water to prevent flood polluting indoor environment. The utility model has simple structure and reliable performance.
Description
A kind of gutter returns water brake, belongs to the pipeline accessory, is specially adapted to the building water drain pipeline.
The existing employed water seal bend pipe of building, the upper end of water seal bend pipe is connected with sanitaryware, and the lower end is connected with discharge pipe line, has the water seal and the soil cleaning port that prevent to return peculiar smell.Its weak point is that when a certain section main drainpipe road of building stopped up, the sewage in the pipeline upwards returned water along pipeline, and sewage can flow into indoor major polluting indoor environment through sanitaryware by the water seal bend pipe, makes troubles to people's life.
It is a kind of when the main drainpipe road is stopped up that the purpose of this utility model is to provide, and can close the last interface that is connected with sanitaryware automatically by returning water pressure, avoids flood to pollute indoor environment, and simple in structure, and the gutter of dependable performance returns water brake.
The purpose of this utility model is realized by following technical scheme: a kind of gutter returns water brake, it comprises the brake body that is connected to form by upper shell (3) and lower house (8), be provided with interface (1) in the upper end of brake body, be provided with cover (13) in the water seal in the intrinsic bottom of brake, lower interface (11), soil cleaning port (15) at the brake body locates to be connected with blanking cover (9), it is characterized in that: fairlead (6) is set at the intrinsic middle part of brake, the bottom of fairlead (6) is provided with porous aquaporin (14), be built-in with brake body (4) at fairlead (6), on the upper cone of brake body (4), be nested with the awl bowl (5) that can seal interface (1).
Gutter of the present utility model returns water brake and compares with existing water seal bend pipe, owing to return preventing of keeping that the water seal bend pipe has on the basis of the water seal of peculiar smell and soil cleaning port structure, having set up again by returning water pressure makes brake body float, bore the bowl sealing is connected interface with sanitaryware structure along fairlead, can avoid flood to pollute indoor environment, have advantages such as simple in structure, dependable performance.
The utility model is described in further detail to utilize embodiment shown in the drawings below.
Fig. 1 returns water brake structure cross-sectional schematic for gutter.
With reference to Fig. 1, this part that gutter returns water brake is threaded with lower house (8) by upper shell (3), is provided with sealing ring (7) at connection of thread.Upper shell (3) adopts plastic mould pressing one-body molded with fairlead (6), and the bottom of fairlead (6) is taper, is provided with the aquaporin (14) that several holes is formed in taper place.Lower house (8) adopts the plastic mould pressing moulding with water seal sleeve pipe (13), lower interface (11).Be built-in with brake body (4) at fairlead (6), brake body (4) adopts plastic mould pressing to make an end band cone, adopts plastic mould pressing to make other end cone more separately, sticks with glue and connects the composition one.Awl bowl (5) adopts corrosion-resistant, withstand voltage top-quality rubber compression molding, will bore bowl (5) and be placed on the upper cone of brake body (4).Last interface (1) is threaded with upper shell (3), is provided with sealing ring (2) at connection of thread, and blanking cover is threaded with lower house (8), is provided with sealing ring (10) at the screw thread place, and blanking cover (9) is sealed soil cleaning port (15).The water level (12) that certain altitude is arranged in the cover (13) in the water seal of the intrinsic below of brake.Last interface (1) and blanking cover (9) equally also adopt the plastic mould pressing moulding.
