Abstract

The utility model relates to a double 45 DEG bend drainage pipe 1 with a flexible joint. The drainage pipe 1 is provided with a socket 2. The socket 2 and the faucet 3 of the connected pipe fitting form a flexible joint through a rubber sealing ring 5, a flange press cover 6, and screws 7. The other end of the drainage pipe 1 is a faucet. In order to conveniently repair, the middle section of the drainage pipe 1 is provided with an inspection opening 8. The inspection opening 8 is sealed by an inspection opening cover 10, a rubber ring 4 and screw bolts 9.

Description

Double 45 degrees bend drainage pipe with flexible joint

The utility model relates to a kind of two 45 ° of elbow water-drainage tube parts that have flexible interface, further relates to a kind of two 45 ° of elbow water-drainage tube parts that have inspection hole and flexible interface.

Employed 45 ° of elbow water-drainage tube parts need two 45 ° of elbow water-drainage tube parts to link together and could form 90 ° of elbow gutters when being used for 90 ° of elbow gutters in the existing design specifications.Because gutter has such interface when turning round, therefore, seepage or drainage often occur in herein.In addition,, when it is used for 90 ° of elbow gutters, often in short length, be formed with the interface more than three, therefore brought many troubles, be unfavorable for accelerating installation rate to fitting operation because this 45 ° of elbow water-drainage tube part length are shorter.

The purpose of this utility model is exactly in order to overcome the shortcoming of above-mentioned existing design specifications, to design a kind of two 45 ° of elbow water-drainage tube parts that have flexible interface, needed interface when being used for 90 ° of elbow gutters to reduce it.In addition, in order to overhaul conveniently, also can be on the interlude of this two 45 ° of elbow water-drainage tube parts that have a flexible interface inspection hole of design.

The purpose of this utility model is to realize like this, designed two 45 ° of elbow water-drainage tube parts that have flexible interface are the iron water-drainage tube parts with integral cast of two 45 ° of elbows, one end of this pipe fitting is the bellmouth that has the big straight warp of flange, be used for forming a flexible interface with the socket of the pipe fitting that links to each other, the other end of this pipe fitting is the socket end isometrical with pipe fitting.Because 90 ° of elbow gutters form obstruction easily in its elbow, for the ease of overhauling, on the interlude of two 45 ° of elbows of this water-drainage tube part, can also increase an inspection hole.

This newly-designed two 45 ° of elbow water-drainage tube parts that have flexible interface, owing in the middle of two 45 ° of elbows, no longer include interface, reduced the interface quantity of whole gutter, thereby simplified fitting operation, the possibility that has reduced this part pipe fitting infiltration simultaneously and leaked.In addition, owing to cancelled an interface, also reduced needed iron of this pipe fitting and accessory, thereby reduced its cost.Have again, if this pipe fitting has inspection hole 1 also to be convenient to overhaul when stopping up.

The utility model is described in further detail below by embodiment and accompanying drawing thereof.

Fig. 1 is the phantom of the said water-drainage tube part of the utility model;

Increased the schematic diagram of an inspection hole on the interlude of Fig. 2 for said water-drainage tube part among Fig. 1;

Fig. 3 is that A among Fig. 2 is to view.

As shown in the figure, the two 45 ° of elbow water-drainage tube parts 1 that have flexible interface have a bellmouth 2, and this bellmouth 2 passes through a rubber seal 5 with the socket 3 of the pipe fitting that links to each other, and flange gland 6 and bolt 7 can form a flexible interface.The other end of this pipe fitting 1 is a socket, for overhauling conveniently, also can design an inspection hole 8 on the interlude of this pipe fitting 1, and inspection hole 8 is by an inspection cap 10, and cushion rubber 4 and bolt 9 seal up.

Claims

1, a kind of two 45 ° of elbow water-drainage tube parts that have flexible interface, it is characterized in that, this water-drainage tube part (1) is an iron water-drainage tube part that the integral cast with two 45 ° of elbows forms, one end of this pipe fitting (1) is the larger-diameter bellmouth (2) that has flange, it can pass through a rubber seal figure (5) with the socket (3) of the pipe fitting that links to each other, and flange gland (6) and bolt (7) form a flexible interface; The other end of this pipe fitting (1) is the socket end isometrical with pipe fitting.

As the said water-drainage tube part of claim 1, it is characterized in that 2, the interlude of water-drainage tube part (1) is provided with an inspection hole (8), this inspection hole (8) is by inspection cap (10), cushion rubber (4) and bolt (9) and sealed.
