Description
Technical field
It the utility model is related to ventilation duct field, more particularly to a kind of tee pipe fitting for fresh air system.
Background technology
The popularization degree of Household fresh air system is higher and higher at present, but for house ornamentation user, since system needs two
Run without interruption within 14 hours, be to be concerned about the most and urgently to be resolved hurrily so the noise problem produced in ventilation duct.
Secondly, normal discharge pipe fitting is used in most fresh air system pipeline on the market, without the dedicated pipe fitting of air hose.By
In not matching for pipe fitting, great windage can be produced wind circulation is out-of-date, so as to reduce the work efficiency of fresh air system.
Utility model content
It is to be the provision of one the purpose of this utility model is that solving noise problem during fresh air system operation in air hose
Tee pipe fitting of the kind for fresh air system, it is simple in structure, it is easy to use, windage can be reduced, increases effective wind rate, improves fresh air system
The operational efficiency of system.
In order to realize above-mentioned purpose, the utility model adopts the following technical solution：
A kind of tee pipe fitting for fresh air system, it includes main pipe body, is responsible for interface, branch pipe interface, its feature exists
In it further includes transition corner and diversion channel, and the transition corner is connected with branch pipe interface and supervisor's interface respectively, described
Diversion channel is connected with main pipe body and supervisor's interface respectively.
Preferably, main pipe body volume is done greatly as far as possible, it might even be possible to does spheroiding.It is further preferred that pipe
Part main body can reserve inspection socket with perforate.
Preferably, it is responsible for interface and branch pipe interface is made of flexible material, in order to the connection with tubing.
Preferably, the angle of transition corner cannot be less than 90 °, can be greater than or equal to 90 °.
Preferably, radius of the sweep of diversion channel as far as possible with transition corner is consistent.
Preferably, pipe fitting inner wall additional layer spongy layer.
Compared with prior art, the beneficial effects of the utility model are：
（1）This tee pipe fitting can reduce windage, increase effective wind rate, improve the operational efficiency of fresh air system；
（2）This tee pipe fitting can effectively reduce the noise produced in air hose.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of tee pipe fitting for fresh air system.
Wherein：1 is main pipe body；2 be main interface tube；3 be branch pipe interface；4 be transition corner；5 be diversion channel.
Embodiment
Embodiment 1：
Below in conjunction with the accompanying drawings and case study on implementation, the specific working mode of the utility model is described in further detail.With
Lower case study on implementation is used to illustrate the utility model, but is not intended to limit the scope of the present invention.
As shown in Figure 1, a kind of tee pipe fitting for fresh air system, it includes main pipe body 1, is responsible for interface 2, branch pipe connects
Mouthfuls 3, it is characterised in that it further includes transition corner 4 and diversion channel 5, the transition corner 4 respectively with branch pipe interface 3 and main
Interface tube 2 is connected, and the diversion channel 5 is connected with main pipe body 1 and supervisor's interface 2 respectively.
After fresh air enters pipe fitting from supervisor's interface 2 of side, due to the effect of diversion channel 5, fresh air can be divided into A, B two
Stock.Wherein tributary A is flowed out along original wind direction from opposite side supervisor's interface 2, and tributary B is then in the guiding of transition corner 4
Under flow to branch pipe interface 3.
If using normal discharge pipe fitting, transition corner 4 and diversion channel 5 are not provided with, most fresh airs can be exported from A
Outflow, and B outlets can only get few air quantity.
Further, the design radian of diversion channel 5 and transition corner 4 are consistent, and reduce windage as far as possible, make fresh air suitable
Profit is flowed out from branch pipe interface 3.
Further, transition corner 4 is right angle or obtuse angle, and great windage can be brought by being designed as acute angle.
Preferably, pipe fitting inner wall additional layer spongy layer, can play the role of eliminating distinguished and admirable noise.
Preferably, the flexible materials such as rubber can be used by being responsible for interface 2 and branch pipe interface 3, on the one hand reduction can be aided in make an uproar
Sound, the connection being on the other hand also convenient between pipeline.
Preferably, the purity requirements of fresh air pipeline are higher, can open inspection socket in main pipe body 1, facilitate pipeline system
The maintenance and cleaning of system.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and replacement can also be made, these change
The scope of protection of the utility model is also should be regarded as into replacement.
