Abstract
The utility model discloses a reducing sound-attenuation pipe fitting which comprises a bottle opening four-way pipe fitting and a spiral bar arranged in the bottle opening four-way pipe fitting. The inner wall close to a bottle opening in the bottle opening four-way pipe fitting is provided with inner threads, a reducing connection part is arranged outside the bottle opening four-way pipe fitting, one end of the reducing connection part is provided with outer threads in matched connection with the inner threads, the inner threads and the outer threads are rectangular threads, and a rubber ring is arranged at the connecting position between the reducing connection part and the bottle opening four-way pipe fitting. The large diameter can be changed into small diameter without an additionally-connected reducing tee and through the reducing connecting part connected outside, raw materials for construction can be decreased, and the engineering cost is reduced. In addition, the spiral bars are arranged in the pipe fitting and the reducing connection part, so that in the drainage process, impact force between water flows and the pipe wall can be decreased, and the reducing sound-attenuation pipe fitting has a good noise elimination function.
Description
Technical field
The utility model relates to a kind of reducing noise reduction pipe fitting.
Background technique
In water construction journey, find to have only reducing tee, reducing cross etc. in the existing pipe fitting, still, in the practice of construction, main flow is arranged to ram's horns, all want threeway or four-way, add the direct part combination of reducing.And part is various like this, the casting long processing time, and manufacture cost is higher.And in drainage procedure, because current collide tube wall easily, bigger noise is arranged when causing draining.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of noise control noise reduction, the pipe fitting that bore can change.
For solving technique scheme, the utility model adopts following technological scheme:
A kind of reducing noise reduction pipe fitting, comprise the bottleneck four-way pipe fitting, and be arranged on spiral bar in the bottleneck four-way pipe fitting, inwall near the mouth of pipe in the described bottleneck four-way pipe fitting is provided with internal thread, described bottleneck four-way pipe fitting is provided with the reducing link outward, one end of described reducing link is provided with the outside thread that can be connected with screw-internal thread fit, and described internal thread and outside thread adopt square threaded form, and the joint of described reducing link and bottleneck four-way pipe fitting is provided with rubber ring.
As optimized technical scheme, be provided with spiral bar on the tube wall of described reducing link equally.
The beneficial effects of the utility model are:
By being connected outside reducer pipe fitting, need not to connect in addition reducing and just heavy caliber can be changed over small-borely, construction can reduce raw material, reduces the engineering cost cost; And in pipe fitting and reducing link, establish spiral bar, in drainage procedure, can alleviate the striking force of current and tube wall, have good de-noising function.When connecting reducer pipe fitting and bottleneck four-way pipe fitting, adopt square threaded form to connect, can guarantee to be connected firmly, utilize the rubber ring of the joint of reducing link and bottleneck four-way pipe fitting, can prevent that matching thread is damaged.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
See also shown in Figure 1, a kind of reducing noise reduction pipe fitting of the present utility model, comprise bottleneck four-way pipe fitting 1, and be arranged on spiral bar 2 in the bottleneck four-way pipe fitting 1, inwall near the mouth of pipe in the described bottleneck four-way pipe fitting 1 is provided with internal thread 3, the described bottleneck four-way pipe fitting 1 outer reducing link 4 that is provided with, one end of described reducing link 4 is provided with the outside thread 5 that can be connected with internal thread 3, described internal thread 3 adopts square threaded form with outside thread 5, and described reducing link 4 is provided with rubber ring 6 with the joint of bottleneck four-way pipe fitting 1.
Wherein, be provided with spiral bar equally on the tube wall of described reducing link 4.
The beneficial effects of the utility model are:
By being connected outside reducer pipe fitting, need not to connect in addition reducing and just heavy caliber can be changed over small-borely, construction can reduce raw material, reduces the engineering cost cost; And in pipe fitting and reducing link, establish spiral bar, in drainage procedure, can alleviate the striking force of current and tube wall, have good de-noising function.When connecting reducer pipe fitting and bottleneck four-way pipe fitting, adopt square threaded form to connect, can guarantee to be connected firmly, utilize the rubber ring of the joint of reducing link and bottleneck four-way pipe fitting, can prevent that matching thread is damaged.
The above only is embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
