Abstract
The utility model discloses an improved swirling flow noise-reduction inspection expansion joint. The improved swirling flow noise-reduction inspection expansion joint comprises a pipe body, the upper port of the pipe body is provided with an expansion joint, the outer wall of the pipe body is provided with a transverse expansion joint, the inner wall of the pipe body is provided with a plurality of flow guide parts which are spirally arranged in an inclined mode at equal intervals, the inclined angel of each flow guide part ranges from 30 degrees to 45 degrees, and a flow guide groove is formed in each flow guide part. The improved swirling flow noise-reduction inspection expansion joint saves installation space, and meanwhile greatly lowers noise and improves structural strength.
Description
Technical field
The utility model relates to a kind of modified model swirling-flow noise-reduction band inspection slip joint.
Background technique
At present, in the construction drainage riser systems, the water-drainage tube part often used, 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, forms each other collision, produces 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 structurally also there is identical deficiency in the pipe fitting with slip joint, haves 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 modified model 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 modified model 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:
Modified model 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, described conducting element angle of inclination, between the 30-45 degree, forms guiding gutter on conducting element.
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 is in actual draining drainage procedure, play the swirling flow shape under the effect of current by conducting element in pipeline, conducting element is the tilting screw setting, the guiding current direction is dirty, now 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.
In addition, the setting of guiding gutter, can increase the effect of water conservancy diversion drainage, improves drainage efficiency, reduces noise.
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, also dwindle conduit shaft simultaneously, make the indoor useful space increase, the utlity model has good Economy and convenient and quick construction, energy-conserving and environment-protective, be beneficial to long-run development.
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 modified model 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 described conducting element 3 angles of inclination, between the 30-45 degree, form guiding gutter 4 on conducting element 3.
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 5.
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.
