Abstract
The utility model discloses a kind of novel draining and vent stacks, including internal drainage pipe, outer ventilation pipe, the internal drainage pipe, which is arranged inside pipe of ventilating outside, to be connect by special connecting piece with outer ventilation pipe, the internal drainage pipe, outer ventilation pipe standpipe is connect with dewatering horizontal tube by special three-way connector, it is provided with several ventholes on the internal drainage pipe, the outer ventilation pipe bottom is connect with extraneous drainpipe by special 90 degree of elbows, the utility model is simple in structure easy to use, can be realized with a kind of pipeline can also be exhausted while taking into account draining, extra holes need not be reserved, and running and comparing is stablized, compare firm, it is not easy to go wrong.
Description
Technical field
The utility model is related to the novel draining of a kind of drainpipe more particularly to a kind of corresponding connector of connection and ventilation are vertical
Pipe.
Background technology
When skyscraper soil stack excludes stain disease, it is ensured that the water seal of trap is not destroyed, so often setting
Specific vent stack is counted, is connected at a certain distance with stain disease standpipe with special connecting tube.This usual way floor space
Greatly, passing through floors facial canal line is more, reserving hole also more, and such percolating water probability is also big, and now there are also unit riser systems
Utility model, can be vented and drain simultaneously, but this system operation is unstable, when impurity is more, easily goes wrong.
Utility model content
To solve the above problems, the utility model provides a kind of novel draining and vent stack, in conjunction with corresponding connector,
The utility model is simple in structure easy to use, exhaust can not make in pipe positive/negative-pressure excessive while draining and influence water seal,
And running and comparing is stablized, and it is relatively more firm, it is not easy to go wrong.
To achieve the above object, the utility model uses following technological means：
A kind of novel draining of the utility model offer and vent stack, including internal drainage pipe, outer ventilation pipe, it is described interior
Draining pipe setting outside ventilate pipe inside is connect with outer ventilation pipe by special connecting piece, the internal drainage pipe, outside
Ventilation pipe standpipe is connect with dewatering horizontal tube by special three-way connector, and several ventilations are provided on the internal drainage pipe
Hole, the outer ventilation pipe bottom are connect with extraneous drainpipe by special 90 degree of elbows.
Further, the internal drainage pipe is connected to outer ventilation pipe by corresponding special connecting piece.
Further, the predominant tube diameter of the interior three-way pipe of the special three-way connector is identical as internal drainage pipe diameter,
It is identical as transverse tube diameter to bypass pipe diameter.
Further, the internal drainage pipe, outer ventilation pipe, special connecting piece use plastic pipe or metal pipe material,
It is adopted when using plastic pipe
With bonding connection, it is threadedly coupled using being used when metal pipe material.
The beneficial effects of the utility model：
The utility model is simple in structure, exhaust can not make positive and negative in pipe press through while draining with a standpipe position
Water seal is influenced greatly, floor space is small, and running and comparing is stablized, relatively more firm, it is not easy to go wrong.

Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment is described further the utility model.
Embodiment 1：As shown in figures 1-8, the present embodiment provides a kind of novel draining and vent stacks, including internal drainage pipe
1, outer ventilation pipe 2, the internal drainage pipe 1, which is arranged inside pipe 2 of ventilating outside, passes through special connecting piece 1-1 and outer ventilation circle
Pipe 2 connects, and the internal drainage pipe 1, outer 2 standpipe of ventilation pipe are connect with dewatering horizontal tube by special three-way connector, described
Several venthole 1-3 are provided on internal drainage pipe 1, the water seal that can be very good to carry out ventilation guarantee trap is not destroyed.
The internal drainage pipe 1, outer top, bottom and the centre position for ventilating pipe 2 are connected by special connecting piece 1-1 respectively, institute
Outer 2 bottom of ventilation pipe is stated to connect by special 90 degree of elbows with extraneous drainpipe, it can be in draining with a standpipe position
Exhaust does not make in pipe positive/negative-pressure excessive and influences water seal simultaneously, and floor space is small, and running and comparing is stablized, relatively more firm, no
It is susceptible to problem.
Further, the internal drainage pipe 1 is installed with the 2 concentric setting of outer ventilation pipe, passes through corresponding special connection
Part 1-1 is connected with, conducive to preferably being drained, being ventilated.
Further, the predominant tube diameter of the interior three-way pipe of the special three-way connector is identical as internal drainage pipe diameter,
It is identical as transverse tube diameter to bypass pipe diameter, the special three-way connector is down stream tee joint connector.
Further, the internal drainage pipe 1, outer ventilation pipe 2, special connecting piece 1-1 use plastic pipe or metal
Tubing is threadedly coupled using bonding connection is used when plastic pipe using being used when metal pipe material, easier for installation, processing
It is simpler.
