Abstract

The present invention relates to a water hammer absorber in which an access coupling port is coupled to a container with a compression method without being bonded with a lead component harmful to a human body while maintaining airtightness to be applied to a water pipe. According to the present invention, an insertion unit (31) into which packing is inserted is formed on an upper portion of the access coupling port (30) to maintain airtightness as the insertion unit is inserted into the container (10). Moreover, a lower circumference of the container (10) is accessed to a compression groove (34) formed in an intermediate portion by being compressed to be retracted by compression with a compression means.

Description

Water Hammer Absorber

The present invention relates to a water hammer absorber that can be applied to a water pipe by joining a connection fastener to a container by a compression method without bonding to a human body with a harmful lead component.

Generally, a water hammer absorber is installed to absorb water hammer phenomenon in which a connection fastener is coupled to an end of a long container to install in a water pipe or the like, and an impact is generated in the pipe when the flow of the fluid suddenly stops or flows in the pipe. have.

1 is a view showing a conventional water hammer absorber,

A piston (2) is provided in a long cylindrical container (1) having one side opened and a connecting fastener (3) is fixed to an open part of the container and is fastened to the piping line Is configured to absorb an abnormal pressure of the fluid while compressing the nitrogen gas while the piston is lifted and raised by the water pressure when the nitrogen gas is filled and an abnormal pressure is generated in the pipeline line.

However, in the state where the connection fastener 3 is inserted into one end of the container 1, the fastener 3 is joined to the outer periphery of the container 1 with the solder 4 because the lead component is inserted between the container 1 and the connection fastener 3 It is possible that the lead component can be eluted by flowing into the inside of the pipe, and particularly, the application of the lead component material to the parts related to the water pipe has a problem that the installation regulations are illegal.

In addition, there is a problem that the process of soldering the periphery after connecting the connection fastener to the container is considerably troublesome and the health of the worker is deteriorated.

Disclosure of Invention Technical Problem [8] The present invention has been proposed in order to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a water hammer which can be applied to a water pipe by joining a connection fastener to a container while keeping airtight, Thereby providing an absorber.

A solution for implementing the above-mentioned object will be described as follows.

A piston is provided inside a long cylindrical container with one side opened and a connecting fastener is fixed to an open part of the container so that nitrogen gas is injected into the container while an abnormal pressure is generated in the pipe line The water hammer absorber for absorbing the abnormal pressure of the fluid while compressing the nitrogen gas by lifting the piston by the water pressure,

Wherein the connection fastener comprises an upper portion formed with an insertion portion having a packing so as to be hermetically fitted into the container and a fastening portion formed at a lower portion thereof so as to be connected to a piping line,

And a lower end portion of the container is connected to the compression groove formed in the middle portion of the connection fastener by push-fitting.

According to the present invention, the lower end portion of the container is connected to the connection groove formed in the middle portion of the connection fastener by being press-fitted into the connection fastener without soldering the connection fastener to the container, so that the airtightness can be maintained while maintaining the solid fastenability , Which has the effect of solving the conventional problems due to soldering.

2 is an exploded perspective view showing the structure of the present invention;
3 is a cross-sectional view showing the pre-coupling state of the present invention.
Fig. 4 is a cross-sectional view showing the combined state of the present invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a cross-sectional view showing a state before coupling according to the present invention, and FIG. 4 is a cross-sectional view showing a coupling state of the present invention. Referring to these drawings,

The water hammer absorber (W)

(10) having one side opened, a piston (20) which ascends and descends in the container (10), and a connection fastener (30) connected to the lower end of the container and fastened to the piping line And,

When an abnormal pressure is generated in the piping line by injecting nitrogen gas into the container 10, the piston 20 is lifted and raised by the water pressure to absorb the abnormal pressure of the fluid while compressing the nitrogen gas.

A packing 32 is provided around the insertion portion 31 formed to be fitted into the container 10 at the upper portion of the connection fastener 30 so that the tightness can be maintained. As shown in Fig.

And the periphery of the container 10 is pressed and connected to the compression groove 34 formed at the middle portion of the connection fastener 30 so as to be pressed down by a pressing means such as a jig.

That is, when the container 10 is inserted into the insertion portion 31 of the connection fastener 30 and the lower end of the container 10 is compressed so as to be pressed down as shown in FIG. 2, 10 are fitted in the compression grooves 34 formed in the connection fastening holes 30 and assembled.

As described above, according to the present invention, since the connection fastener 30 is fastened to the lower end of the container and is fastened to the container, it is possible to enhance the fastenability, and the insertion of the fastener 30 inserted into the container 10, It is possible to provide the water hammer absorber in which the portion 31 is sealed by the packing 32 to maintain the double airtightness.

In particular, according to the present invention, the joining operation by the soldering operation is eliminated, so that the joining operation can be easily performed by the jig means while the joining structure is securely coupled.
