Abstract

The present invention relates to an apparatus for discharging and blocking air inside a water pressure test chamber which comprises: a housing having a discharge hole formed thereon; a seal plug which is embedded in the housing to move along a center axis of the discharge hole; and a float which is installed on the seal plug to come in contact with the discharge hole. As liquid is filled in the water pressure test chamber, the float blocks the discharge hole formed on the housing. Therefore, the water pressure test chamber can be automatically enclosed. Pressure change, caused as the water pressure test chamber is pressed to a pipe body extended from the water pressure test chamber to the outside, does not occur. Therefore, the apparatus for discharging and blocking air inside a water pressure test chamber has an effect of preventing the pipe body from being damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, it should be noted that the same components or parts among the drawings denote the same reference numerals whenever possible.

In the description of the present invention, a detailed description of related arts will be omitted in order not to obscure the gist of the present invention.

1 through 8, the apparatus for discharging and interrupting the internal pressure of the hydrostatic test chamber according to the present invention includes a housing 100 having a discharge hole 111 formed thereon, And a float 300 mounted on the seal plug 200 so as to be in contact with the discharge hole 111. [

The housing 100 includes an upper surface 110 having a discharge hole 111 formed therein, a tube portion 120 extending in a tubular shape from the upper surface 110, and a donut-shaped wing 130 formed on the outer circumferential surface of the tube portion 120 ).

A release preventing member (140) for preventing the release of the seal plug (200) is provided inside the tube portion (120). The release preventing member 140 includes a circular groove 141 formed in the inner wall surface of the tube portion 120 so as to be perpendicular to the longitudinal axis of the tube portion 120 and a snap ring 142 mounted on the circular groove 141 do.

Mounting grooves 131 and 132 for mounting two O-rings O-1 and O-2 having different diameters are formed in the wing portion 130, A plurality of mounting holes 133 are formed.

That is, the tube portion 120 of the housing 100 is inserted into the discharge port E formed in the hydrostatic test chamber C and the bolt is inserted into the bolt mounting hole 133 formed in the wing portion 130, The housing 100 is fixed to the hydrostatic test chamber C by being screwed to the inner wall of the test chamber C (see Fig. 8).

It is preferable that the housing 100, the seal plug 200 and the float 300 are made of a material whose shape change is small even under a large pressure change.

The seal plug 200 includes a face portion 210 which is horizontally aligned with the upper surface 110 and has a mounting hole 211 formed at its center and a wall portion which is vertically extended from the face portion 210 to be in contact with the inner wall of the pipe portion 120 220).

A longitudinal groove 221 is formed on the outer surface of the wall 220 so as to form a gap between the tube portion 120 and the wall portion 220.

A plurality of the longitudinal grooves 221 may be formed in a straight line shape along the longitudinal direction of the wall portion 220 (see FIG. 4), or may be formed in a curved shape so as to form multiple strands along the outer surface of the wall portion 220 (See FIG. 5A), and may be formed in a screw shape to form a single helix along the outer surface of the wall 220 (see FIG. 5B).

Air or injected water in the hydrostatic test chamber C rapidly flows into the discharge hole 111 of the housing 100 along the length groove 221 formed in the seal plug 200 (see FIG. 7).

The float 300 includes a contact surface portion 310 having a larger diameter than the discharge hole 111 and a fixed post portion 320 protruding from the center of the contact surface portion 310 and inserted into the mounting hole 211 .

The contact surface portion 310 is formed with an O-ring groove 311 on which an O-ring O-3 having a larger diameter than the discharge hole 111 is mounted.

A separation preventing member 330 for preventing the fixing post 320 from being detached from the mounting hole 211 is provided at an end of the fixed post 320. The detachment preventing member 330 prevents the float 300 from being inadvertently brought into close contact with the housing 100 as the float 300 is not subject to movement of the seal plug 200.

The detachment preventing member 330 includes a mounting groove 331 formed at an end of the fixed column portion 320 so as to be perpendicular to a longitudinal axis of the fixed column portion 320 and a snap ring 332 mounted to the mounting groove 331, .

7 and 8, as the water is injected into the initial hydraulic test chamber C, the air existing in the hydraulic test chamber C along the longitudinal groove 221 formed in the seal plug 200 Flows into the discharge hole (111) of the housing (100) and is discharged outside the water pressure test chamber (C).

As the water pressure test chamber C is filled with water, the upper end of the seal plug 200 comes into contact with the inside of the upper surface of the housing 100. At this time, the float 300 mounted on the seal plug 200 comes into contact with the upper surface of the housing 100, and ultimately the upper surface of the float 300, that is, the contact surface portion 310 and the contact surface portion 310 The o-ring (O-3) provided is closely attached to the housing 100 to seal the hydraulic test chamber (C).

As the water is injected into the hydraulic test chamber C, the pressure for pressing the seal plug 200 and the float 300 increases, thereby sealing the hydraulic test chamber C more firmly.

As a result, no pressure is applied to the tube (not shown) extending to the ground from the water pressure test chamber C so as to discharge the air in the water pressure test chamber C, so that the tube body is not damaged. Further, since the time for closing the hydraulic test chamber C is determined without any special operation, the pressure in the hydraulic test chamber C is facilitated. Particularly, since the valve operation force for sealing the hydraulic test chamber (C) is not required, the equipment manpower can be reduced.

Although the present invention has been described with reference to the drawings illustrating the air venting and shutting device in the hydraulic test chamber according to the present invention, the present invention is not limited to the embodiments and drawings disclosed herein, It will be understood by those skilled in the art that various changes may be made therein without departing from the spirit and scope of the invention.
