Abstract

The utility model relates to a novel elbow piece of which the bend angle ranges from 19 DEG to 50 DEG. The utility model can be connected with a tee joint provided with a bell mouth, and can solve the problem that the existing elbow piece can not be matched with new sanitary ware.

Description

Novel elbow

The utility model relates to a kind of novel elbow, is mainly used in toilet drainage, belongs to the technical field of blowdown pipe fitting.

Present newly-built residenter house, office building, or the hotel, generally install sanitary equipment (being flush toilet), because the standardization in house lavatory and supporting sanitary equipment, mostly adopt the elbow of 45 degree or 90 degree bent angles, be connected with sanitary equipment with threeway, the elbow center line is everlasting from the distance of wall, and this elbow of installation suits the novel sanitary equipment that existing market is commonly used between the 400mm-600mm, owing to the 200-300mm that is reduced to of spacing, original elbow just is difficult to supporting use.

The purpose of this utility model is that a kind of novel elbow will be provided, and it can overcome above-mentioned shortcoming, novel elbow be bent angle θ between 19-50 °, the best be 19 the degree bent angles, use this elbow, make installation and maintenance all simple and easy.

The purpose of this utility model is achieved in that a kind of novel elbow, and the bent angle θ that it is characterized in that elbow is 19-50 °, can be connected with bellmouth (2) with threeway (3).

The novel elbow schematic representation of Fig. 1;

By Fig. 1, the bent angle θ of elbow (1) is approximately 19-50 °, and threeway (3) upper end diameter overstriking forms a bellmouth (2) and is connected with elbow (1) lower end.

At Fig. 1, the center line of threeway (3) from wall apart from d, elbow (1) upper end center line is s from the distance of wall, the data list of Ceing is in descending factually: threeway from wall apart from the d elbow from wall apart from s θ

(the sanitary equipment delivery port is apart from the wall distance) 120 208 21.5 ° 120 220 24.6 ° 120 305 50 ° 150 208 14 ° 150 220 17 ° 150 305 40 °

According to the optimal cases of installing, when the s distance is 220 or 208mm, and when being 120mm apart from d, the θ angle can be selected for use by numerical value in the table.

Therefore, select elbow of the present utility model for use, can cooperate and select novel sanitary equipment or other sanitary equipment for use, very easy to be suitable during installation.

Compared with prior art, novel elbow has following advantages:

1, elbow bent angle θ changes 19-50 ° into, is suitable for existing mounting condition;

2, avoided the contradiction that size is not inconsistent between construction code requirement and the novel sanitary equipment.

Claims (1)

1, a kind of novel elbow, the bent angle θ that it is characterized in that elbow is 19-50 °, can be connected with bellmouth (2) with threeway (3).
