Abstract

The utility model provides air supply fittings for drainage way, which includes an annular case with top and bottom ends open and a drainage way formulated by annular cases. A windway is distributed on the walls on the top of the case along the top end to the lower part of the case. The lower end of the windway is communicated with the drainage way within the case at the top, middle, or lower part of the case. The utility model may supply air within the drainage way to avoid the damage due to the negative pressure in the pipe. The utility model is simple in structure and easy for installation, which will effectively fix the drainage pipe system and prevent the falling off.

Description

The tonifying Qi pipe fitting of drainage pipe

Technical field

The utility model relates to a kind of accessory that is applicable to drainage pipe, relates generally to the tonifying Qi pipe fitting of drainage pipe.

Background technology

In the prior art, the conduit coupling that is to use that mostly adopts between the drainage pipe directly connects, particularly be installed in the rain-water drainage pipeline of skin, all be to adopt tubing to be connected or bonding with the pipe fitting tight fit, and because the length of drainage pipe, caliber, factors such as material, cause the fluctuation of gutter internal pressure easily, produce parital vacuum in the pipe, when the standpipe drain discharge is big, forms the swabbing action of negative pressure in short-term in riser upper, and cause breaking of drainage pipe, damage, cause and normally to use, for addressing the above problem, loose fit between the tubing of employing and the pipe fitting is also arranged, fixing by fixedly sticking into row, like this, it is unstable to cause whole tubing to be installed, and can cause along with fixing card to fluff to form between tubing and the pipe fitting to disconnect, and influences the result of use of whole pipe.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technological deficiency, and a kind of tonifying Qi pipe fitting of drainage pipe is provided.Adopt the utility model to avoid managing interior negative pressure and to cause pipeline destroyed carrying out tonifying Qi in the drainage pipe, simultaneously simple in structure, easy for installation, effectively fixedly sewerage system can not come off.

For achieving the above object, the technical solution adopted in the utility model is:

The tonifying Qi pipe fitting of drainage pipe, comprise the drainage channel that upper and lower port is uncovered circular shell, is formed by circular shell, it is characterized in that: be distributed with along the housing upper port to the lower housing portion direction air duct that is provided with on the wall on described housing top, the lower port of air duct on housing top or middle part or bottom communicate with drainage channel in the housing.

The inside wall height of described housing upper port is higher than upper port outer wall height, and the inwall upper end is outward extended with splash guard.

Described inner walls is extended with upper limit position block at the lower port place of air duct in drainage channel.

Shell inner surface in distance air duct lower port a distance is provided with lower position block.

Described air duct is at least one.

The top thickness of described housing is greater than bottom thickness.

Advantage of the present utility model is:

1, owing to increased air duct on pipe wall, air can freely be entered in the drainage pipe, to carrying out tonifying Qi in the drainage pipe, negative pressure causes pipeline destroyed in avoiding managing.

2, above air duct, increased splash guard, made air duct can not strengthen the free flow of air because of the rainwater in the external world or foreign matter etc. enter drainage pipe by air duct

3, adopt integral prefabricated structure, simple in structure, easy for installation, only drainage pipe need be inserted from the two ends of tonifying Qi pipe fitting and get final product, and housing in upper and lower spacing can make drainage pipe effectively spacing, guarantee that air freely enters, and can adopt tight fit such as bonding to be connected between drainage pipe and the tonifying Qi pipe fitting, can effectively guarantee the globality of sewerage system, can not come off.

Description of drawings

Fig. 1 is the utility model sectional structure schematic diagram.

Fig. 2 is that the A-A of Fig. 1 is to the sectional structure schematic diagram.

Mark among the figure: 1 is circular shell, and 2 is inwall, and 3 is drainage channel, and 4 is splash guard, and 5 is air duct, and 6 is upper limit position block, and 7 is lower position block.

The specific embodiment

Embodiment 1:

The tonifying Qi pipe fitting of drainage pipe, comprise, lower port is uncovered circular shell 1, the drainage channel 3 that forms by circular shell 1, circular shell 1 cross section can be circular according to actual needs, rectangle, or polygon, the top thickness of described circular shell 1 is greater than bottom thickness, be distributed with the air duct 5 that 1 bottom direction is provided with along housing 1 upper port to housing on the wall on described circular shell 1 top, air duct 5 can be one or more, and distribute along the circular shell wall, the lower port of air duct 5 communicates with the drainage channel of housing 1 inside, the position that communicates can be on the top of housing 1, middle part or bottom, described inner walls is extended with upper limit position block 6 at the lower port place of air duct in drainage channel.Housing 1 inner surface in distance air duct 5 lower port a distance is provided with lower position block 7.

In use, drainage pipe is inserted from last lower open mouth respectively, and limit the position and the degree of depth that drainage pipes insert by upper limit position block 6 and lower position block 7, adopt tight fit modes such as bonding simultaneously between drainage pipe and the tonifying Qi pipe fitting, when draining, because air can freely enter drainage pipe by air duct 5, does not damage pipeline with regard to not forming negative pressure in drainage pipe.The utility model adopts integral prefabricated structure, simple in structure, easy for installation, only drainage pipe need be inserted from the two ends of tonifying Qi pipe fitting and get final product, and housing in upper and lower spacing can make drainage pipe effectively spacing, guarantee that air freely enters, can effectively guarantee simultaneously the globality of sewerage system, can not come off.

Embodiment 2:

As a same reason, the inwall 2 of housing 1 upper port can also be increased to certain altitude, make it be higher than upper port outer wall height, and extend outward splash guard 4 in inwall 2 upper ends, like this, make air duct can not strengthen the free flow of air because of the rainwater in the external world, foreign material etc. enter drainage pipe 3 by air duct 5.

The utility model is not limited to above-mentioned embodiment.
