Abstract

PURPOSE: An elbow pipe with an anti-noise member is provided to prevent fluid from being directly contacted to the inner surface of the elbow pipe by dispersing the fluid with an anti-noise member installed inside the elbow pipe, thereby preventing impact noise generated when the fluid impacts on the inner wall of the elbow pipe. CONSTITUTION: An elbow pipe (10) comprises an anti-noise member (100) and multiple through-holes (110). The anti-noise member is a conical funnel shape and is installed inside the elbow pipe. The top of the anti-noise member is positioned in an inlet pipe. The through-holes are formed along the outer circumference of the anti-noise member.

Description

ELBOW PIPE WITH NOISE PROTECTION METHOD {ELBOW PIPE HAVING MEMBER FOR PREVENTING NOISE}

The present invention relates to an elbow tube provided with a noise preventing member, and more particularly, by installing a noise preventing member inside the elbow tube to disperse the transported fluid so that the fluid does not directly contact the inner surface of the elbow tube. The present invention relates to an elbow tube provided with a noise preventing member for preventing collision noise generated when a fluid collides with an inner wall of the elbow tube.

Generally, the pipe joint elbow 10 is used to connect the inflow pipe 20 and the discharge pipe 30 to switch the flow direction of the fluid, as shown in FIG. And a bent portion is provided between the discharge side connection portion.

On the other hand, pipes for fluid transfer pipes such as sewage pipes and drainage pipes and pipe joints including elbows cause noise in the process of fluid transfer. It collides with the inner wall (area A of FIG. 1) of (10) and severe noise is generated.

Thus, elbows for pipe joints are developed and used to reduce the transfer noise of the fluid.

Conventional pipe joint elbows have a space portion formed between the inner and outer tubes, or a foam core is provided between the inner and outer tubes, or a soft layer is formed inside or outside the hard tube. This situation is mainly used.

In the case of forming the space portion between the inner tube and the outer tube of the conventional pipe joint elbow, there is an effect that the impact noise caused by the collision of the inner tube and the fluid is absorbed and alleviated to some extent in the space portion. There was a problem that the vibration is generated in the end can not get a complete sound absorbing effect, the rest of them can also expect some noise reduction effect, but perfect noise blocking was difficult.

The present invention is to solve the above problems, an object of the present invention is to install a noise preventing member in the interior of the elbow pipe dispersing the fluid to be transported so that the fluid is not in direct contact with the inner surface of the elbow pipe fluid It is to provide an elbow tube provided with a noise preventing member for preventing the collision noise generated when the collision with the inner wall of the elbow tube.

According to the present invention, in the elbow pipe interconnecting the inlet pipe and the discharge pipe, is formed in the conical funnel shape is installed inside the elbow pipe, the top of the cone is installed to be located on the inlet pipe side And a plurality of flow holes formed along the outer circumference of the noise preventing member.

In addition, the plurality of flow holes may be formed in the lower region of the noise prevention member.

In addition, the lower end of the noise prevention member may be formed to a diameter corresponding to the inner diameter of the elbow tube may be fitted into the interior of the elbow tube and fixed.

In addition, the upper vertex of the noise prevention member may be located on the inflow direction of the incoming fluid.

This prevents the impact noise generated when the fluid collides with the inner wall of the elbow tube by distributing the noise preventing member inside the elbow tube to disperse the conveyed fluid. It is effective.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

The elbow tube provided with the noise preventing member according to the present invention, as shown in Figures 2 and 3, the elbow tube 10 and the conical funnel shape that interconnects the inlet pipe 20 and the discharge pipe (30) Is formed in the interior of the elbow tube 10, the top of the cone is installed so that the noise prevention member 100 and the plurality of formed along the outer periphery of the noise prevention member 100 is installed on the inlet pipe 20 side Flow hole 110 is included.

Elbow tube 10 is a general bending tube widely used, regardless of its size or shape, is composed of a form in which the inlet pipe 20 and the discharge pipe 30 are respectively coupled to both sides.

The noise preventing member 100 is formed in a conical funnel shape and is fixedly installed in the elbow tube 10. At this time, the lower end (lower end of Figure 2) of the noise prevention member 100 is formed to a diameter corresponding to the inner diameter of the elbow tube 10 is fitted into the interior of the elbow tube 10 is fixed. Here, the noise preventing member 100 may be simply inserted into the elbow tube 10 and fixed, but may be fixed by a separate fixing means such as an adhesive material for a more secure fixing.

The noise preventing member 100 fixed as described above is installed so that the upper end of the cone, that is, the vertex portion of the cone, is positioned on the inflow direction of the fluid flowing into the elbow tube 10. This is to alleviate the impact by dispersing the incoming fluid.

In addition, the outer periphery of the noise prevention member 100 is formed with a plurality of flow holes 110 are spaced apart from each other along the outer periphery. Flow hole 110 is perforated a plurality along the outer periphery in the lower side region of the noise prevention member (100). The flow hole 110 is distributed by the upper end side of the noise prevention member 100 to transfer the fluid to which the shock is alleviated to the discharge pipe 30 side.

Hereinafter, with reference to Figure 4 will be described the operation of the elbow tube provided with a noise preventing member according to the present invention.

When the fluid is dropped from the upper through the inlet pipe 20, the falling fluid is in contact with the upper end of the noise prevention member 100 and distributed along the noise prevention member 100 to mitigate the impact.

Thereafter, the shock-relieving fluid is transferred through the flow hole 110 and discharged to the discharge pipe 30 side.

As described above, since the fluid is dispersed by the noise preventing member 100 to mitigate the impact of the fluid to be transferred to the discharge pipe 30, the fluid does not directly contact the inner surface of the elbow tube 10 so that the fluid is There is an effect of preventing the collision noise generated when colliding with the inner wall of the storage (10).

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. It will be understood that various changes and modifications may be made without departing from the scope of the present invention.
