Abstract
The utility model discloses a swirling flow noise reduction telescopic joint with an inspection port. The swirling flow noise reduction telescopic joint with the inspection port comprises a pipe body. A telescopic joint body is arranged on the upper end port of the pipe body, and a transverse telescopic joint body is arranged on the outer wall of the pipe body. A plurality of flow guide parts arranged in a inclined and spiral mode are arranged on the inner wall of the pipe body. The thickness of the flow guide parts is 2-5mm, and the length of the flow guide parts is 15-25cm. According to the swirling flow noise reduction telescopic joint with the inspection port, the installation space is saved, the noise is greatly lowered, and the structural strength is improved.
Description
Technical field
The utility model relates to a kind of swirling-flow noise-reduction band inspection slip joint.
Background technique
At present, the water-drainage tube part often used in the construction drainage riser systems, due to inner wall smooth, current are difficult to form effective moisture film structure, so, in whole drainage procedure, the water-bound disorder that pipe interior falls is unordered, form each other collision, produce noise.And, also retaining air in water pipe, can not discharge in order, now between air and current, also can collide the formation noise, to home environment, exert an influence, reduce people's quality of life.
Wherein for drainage system slip joint pipe fitting, structurally also there is identical deficiency, have much room for improvement.
Addressing these problems is extremely urgent as from the foregoing!
In view of this, the inventor has done deep research to this, designs a kind of swirling-flow noise-reduction band inspection slip joint, saves installing space, greatly reduces noise simultaneously, improves structural strength, and this case produces thus.
The model utility content
The purpose of this utility model is in order a kind of swirling-flow noise-reduction band inspection slip joint to be provided, to save installing space, greatly reduce noise simultaneously, improving structural strength.
For achieving the above object, the technical solution of the utility model is:
Swirling-flow noise-reduction band inspection slip joint, it is characterized in that: comprise body, upper end-hole at body is provided with slip joint, be provided with horizontal slip joint on tube wall, inwall at body is provided with some tilting screw formula conducting elements that uniformly-spaced arrange, the thickness of described conducting element is between 2-5mm, and length is at 15-25cm.
Further, described conducting element apart from the lateral extensometer casing coupling the distance at 5-10cm.
Further, described tube wall is provided with stiffening rib.The setting of this structure, can increase the structural strength of body.
Further, the outside of described slip joint is provided with wear ring.This structure can be protected the structural strength of strengthening the slip joint outside, improves the fastness used in installation process.
The utility model swirling-flow noise-reduction band inspection slip joint, in actual draining drainage procedure, current in pipeline, be provided with by the inwall at body under the effect of some tilting screw formula conducting elements that uniformly-spaced arrange and play the swirling flow shape, being attached to inner-walls of duct formation hollow drops, make air exhaust from bottom to top under the effect of swirling flow hydraulic pressure in pipeline, do not have negative pressure to produce, make lower water flow significantly improve.Under simultaneously because current adhere to the inner-walls of duct swirling flow, room noise is obviously reduced, home environment is good.
The beneficial effects of the utility model: the problem between the utility model can solve waste pipe internal drainage in high-rise, skyscraper and ventilate, use less tubing, take less space, just can surmount the effect of traditional drainage system, improve the deficiency in existing drainage system.
The utility model is saved pipeline 50% simultaneously, also dwindles conduit shaft, makes the indoor useful space increase, and the utlity model has good Economy and convenient and quick construction, and energy-conserving and environment-protective, be beneficial to long-run development simultaneously.
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to accompanying drawing 1, the present embodiment discloses a kind of swirling-flow noise-reduction band inspection slip joint, it is characterized in that: comprise body 1, upper end-hole at body 1 is provided with slip joint 2, be provided with horizontal slip joint 2 on body 1 outer wall, inwall at body 1 is provided with some tilting screw formula conducting elements 3 that uniformly-spaced arrange, and the thickness of described conducting element 3 is between 2-5mm, and length is at 15-25cm.
Further arrange, described conducting element 3 apart from the distance of lateral extensometer casing coupling 2 at 5-10cm.
Further arrange, described body 1 outer wall is provided with stiffening rib.
Further arrange, the outside of described slip joint 2 is provided with wear ring 4.
The foregoing is only an embodiment of the present utility model, not to the restriction of this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
