Abstract

The utility model discloses a reflux prevention drainage device, comprising a water intake section and a drainpipe. A blocking ball is arranged on the joint of the water intake section and the drainpipe. A moveable section is provided behind the blocking ball. The utility model has the advantages of simple structure, easy manufacture, and easy maintenance and can not be damaged easily. Once clogging occurs, the sealing cover of a maintenance opening can be opened to clean conveniently and eliminate the clogging in time. The utility model can be arranged on various indoor outfalls of floor drains, closets or urinals, water pools, etc. The reflux prevention drainage device can stop reflux from the indoor outfalls and has a better effect of preventing the backflow of foul smell.

Description

The anti-reverse water device that flows down

(1), affiliated field

The utility model relates to a kind of dewatering installation of building, the device that ducted sewage flow backwards when specifically a kind of sewer pipe that prevents building stopped up.

(2), background technology

Sewer pipe in the building all is to connect mutually, in case lower floor occur to stop up, row's sewage down will accumulate in obstruction place above, in the ground leak of the most close obstruction, closestool port etc. and indoor identical outfall place adverse current inlet chamber, pollute indoor environment, destroy inside plant.Though all have enclosed constructions such as water seal on floor drain, closet, these enclosed constructions generally can only play the effect of anti-odor, can not play the effect of anti-adverse current, and the effect of its anti-odor is also unsatisfactory.Some reports of the device with anti-adverse current effect are also arranged, but the structure more complicated of these devices, not only cost height, and maintenance is inconvenient, and drawing clearly after particularly stopping up is extremely inconvenient.

(3), summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, easy to installation and maintenance, be convenient to draw clearly the broad-spectrum anti-reverse water device that flows down.

The purpose of this utility model is achieved in that it comprises inlet segment and gutter, is provided with closure ball in the junction of inlet segment and gutter, has one section to move section behind the closure ball.

The utility model can also comprise some architectural features like this:

1, after moving section, is provided with service ports, has seal cover on the service ports.

2, described inlet segment " U " type pipe that communicates with ground leak or outfall, the port of export of inlet segment is a bell, closure ball places the bell place, mobile section be connected in bell after, have the delivery port that communicates with gutter on the linkage section.

3, described inlet segment is the taper inclined tube that communicates with closet, mobile section be connected in the taper inclined tube after, gutter and taper inclined tube intersect and communicate, closure ball places gutter and taper inclined tube intersection.

4, described service ports is arranged at the rear portion of closet.

5, described service ports is arranged at a side of closet.

6, described service ports is arranged at the rear portion and a side of closet.

Advantage of the present utility model is: only increase simple structures such as being provided with closure ball and just can reach good anti-adverse current effect, simple in structure, not fragile, easy manufacturing, easy to maintenance on general drainage pipe; Be provided with service ports in the utility model,, can open the seal cover on the service ports, draw processing easily clearly, in time get rid of and stop up in case stop up; The utility model can be arranged at various indoor drainage mouths places such as ground leak, closet, sink waste, and can stop sewage fully takes place from the phenomenon that the indoor drainage mouth flows backwards, and can reach the effect of better anti-odor.

(5), specific embodiments

For example the utility model is done description in more detail below in conjunction with accompanying drawing:

In conjunction with Fig. 1-Fig. 3, the composition of first kind of embodiment of the present utility model comprises inlet segment and gutter 2, is provided with closure ball 3 in the junction of inlet segment and gutter, has one section to move section 4 behind the closure ball.Be provided with service ports 5 after moving section, have seal cover 6 on the service ports, seal cover is threaded with service ports.Inlet segment " U " type pipe 1 that communicates with ground leak or outfall, the port of export of inlet segment is a bell, closure ball places the bell place, mobile section be connected in bell after, have the delivery port 7 that communicates with gutter on the linkage section.The structure of present embodiment is suitable for locating to install and use in ground leak, sink waste etc.Under the effect of the impulse force of water, closure ball prolongs and moves section and rise during draining, and water can be discharged from gutter unobstructedly.When not having water to discharge, closure ball can seal delivery port, in case take place to stop up aqueous reflux is arranged, and closure ball can not flow backwards the delivery port sealing.Can draw processing easily clearly after opening the seal cover on the service ports.

In conjunction with Fig. 6 and Fig. 6, the composition of second kind of embodiment of the present utility model comprises inlet segment and gutter 2, is provided with closure ball 3 in the junction of inlet segment and gutter, has one section to move section 4 behind the closure ball.Be provided with service ports 5 after moving section, have seal cover on the service ports, service ports can be opened rear portion, a side or rear portion and the side at closet.Described inlet segment is the taper inclined tube 11 that communicates with closet, mobile section be connected in the taper inclined tube after, gutter and taper inclined tube intersect and communicate, closure ball places gutter and taper inclined tube intersection.The present embodiment is suitable for installing and using at outfall places such as closets.
