Description

APAPATUS FOR PREVENTING DAMAGE AND NOISE OF PIPE LINE USING SUCTION OF NONELASTIC}

The present invention relates to an apparatus for preventing breakage and noise of pipelines by absorbing water hammer energy generated when the flow path is rapidly cut off installed on the pipeline, in particular, manufacturing cost while significantly reducing the number of assembly parts using inelastic materials. The present invention relates to a device for preventing damage to a pipeline and preventing noise by using a non-elastic material having excellent shock absorption in a pipeline, without requiring maintenance and maintenance.

In general, in the pipeline, noise is generated due to a water hammer generated when the fluid flow is rapidly blocked, resulting in breakage of the pipeline.

Therefore, in the related art, this is solved by using a vessel in which gas is injected in the middle of the pipeline to a pipeline, or using a shock absorber using a gas, a spring, and a piston together.

In the case of using a gas, a spring, and a piston, the more the state of use of the piston, the lower the durability and the less reliable the operation.

In addition, there is a water-absorbing device directly connected to the pipeline to operate by a mechanical mechanism, but this has the disadvantage of complicated manufacturing and increasing installation costs.

Therefore, the present invention was devised in view of the above circumstances, while significantly reducing the number of assembly parts, and lowering the manufacturing cost and maintaining no additional maintenance, and the breakage of the pipeline using the absorbency of the inelastic material with excellent shock absorption in the pipeline and The object is to provide a noise suppression device.

Specific means of the present invention for achieving the above object,

In the device for protecting the pipeline (P) from the sudden water hammer energy of the fluid,

An inelastic housing (20) having a non-elastic material storage chamber (22) connected on the conduit (P) and communicating therein in the direction of the conduit (P);

An inelastic material 30 having a water hammer contact surface 32 having a wavy shape is disposed on an inner circumferential surface of the inelastic housing 20.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a cross-sectional view of the installation of the pipeline breakage prevention device according to an embodiment of the present invention, FIG. 2 is an enlarged cross-sectional view taken along line AA of FIG. 1, and FIG. 3 is a cross-sectional view of the installation of the pipe breakage and noise prevention device according to another embodiment of the present invention. .

As shown in FIGS. 1 and 2, in order to prevent damage and noise of the pipeline P from rapid water hammer energy generated in the pipeline P, an inelastic housing 20 is connected on the pipeline P. The non-elastic material 30 having the water hammer contact surface 32 is filled in the inner wall of the non-elastic material housing 20.

The inelastic housing 20 has an inlet 21a and an outlet 21b for connecting on the pipeline P, and has an inelastic storage chamber 22 in communication with the inlet and outlet 21a, 21b. have.

In addition, the inelastic material 30 is filled in the inelastic storage chamber 22 of the inelastic housing 20 to be inelastically deformed by water hammer energy, and the inelastic material 30 may be used to maximize the contact interview of the water hammer energy. The inner water hammer contact surface 3 is composed of a wave shape.

In this embodiment configured as described above, when the fluid flowing in the pipe P in FIG. 1 is rapidly blocked, water hammer energy is generated due to rapid pressure change.

This water hammer energy is transmitted to the inelastic storage chamber 22 in the inelastic housing 20 connected to the pipeline P, and acts on the inner circumferential surface of the inelastic body 20 filled in the inelastic storage chamber 22.

At this time, it is important that the water hammer energy acts on the inner water hammer contact surface 32 of the non-elastic material 20 so that the non-elastic material 20 is inelastically deformed instantaneously, and then gradually recovers to its original state. do.

That is, both the horizontal elastic waves and the vertical acoustic waves of the water hammer energy act on the non-elastic material 20 to have an excellent water absorption energy absorption effect.

Therefore, the breakage and noise of the pipeline P are not generated due to the rapid disappearance of the water hammer energy generated in the pipeline P.

Meanwhile, the present invention may include an air layer 30a in the inelastic material 30 as shown in FIG.

In this case, the water hammer energy generated in the pipe P is doubled in the air layer 30a together with the water hammer contact surface 32 of the non-elastic material 30.

At this time, the air layer (30a) may be composed of a plurality, the shape may have a variety of forms for the purposes of the present invention.

The present invention constructed and acted as above is simple in configuration and semipermanently usable, and has high reliability of operation.

As described above, according to the present invention, it is possible to absorb the water hammer energy using the non-elastic material in the non-elastic body housing to prevent breakage of the pipeline and noise.

In addition, the configuration is simple and easy to assemble has the advantage of excellent durability and low installation cost.
