[

At this time, the resistance generating means 87 is provided on one side of the second support base 30 so as to be positioned above the second fixing mechanism 60.

Hereinafter, a method of testing whether a leaked pipe occurs in a pipe pipe 1 bent in a U-shape using the water pressure tester constructed as described above will be described.

7 to 9, both ends of the pipe pipe 1 are fixed to the first and second fixing mechanisms 30 and 60, and as shown in Fig. 10, The first and second connection tabs 40 and 70 are advanced by using the means 42 and 72 so that the first and second connection tabs 40 and 70 are firmly fixed to both ends of the pipe pipe 1 As shown in FIG. 11, the first and second connection tabs 40 and 70 are connected to each other by a pipe pipe 1.

11, when the pressurizing pump 83 is operated, the water stored in the water storage tank 81 flows through the water supply pipe 82 and the first connection tab 40 to the pipe pipe 1 ).

When the inside of the piping pipe 1 and the drain pipe 84 are exhausted by the water supplied to the inside of the piping pipe 1 and then the opening and closing valve 85 is locked, The pressurized water is prevented from being discharged to the drain pipe 84 and the pressure inside the water pipe 82 and the pipe pipe 1 and the drain pipe 84 is increased.

Therefore, the operator can check the pressure measuring means 88 to check the degree of the pressure rise in the water supply pipe 82, thereby testing whether or not the pipe pipe 1 is leaked.

12, after the opening / closing valve 85 is opened and the control valve 86c of the air supply means 86 is opened, the air compressor (not shown) High pressure air supplied by the air supply pipe 86b is supplied to the water supply pipe 82 and the pipe pipe 1 and the water discharge pipe 84 through the air supply pipe 86a so that the water supply pipe 82 and the pipe pipe 1, And pushes out the water filled in the inside of the water tank 84, and the water thus pushed out is circulated to the water storage tank 81.

When the water in the water supply pipe 82, the pipe pipe 1 and the pipe pipe 1 is exhausted as described above, the control valve 86c is closed and the first and second fixing mechanisms 30 60 are released from the piping pipe 1 and the piping pipe 1 is removed and both ends of the new piping pipe 1 are fixed to the first and second fixing mechanisms 30, 60. By repeating the above- The leakage test of the pipe pipe 1 can be repeatedly performed.

The water pressure tester configured as described above includes a support frame A and first and second fixing units B and C that are spaced apart from each other in the support frame A and are coupled to both ends of the pipe pipe 1, C and a high pressure water supply pipe connected to the first and second fixed units B and C and connected to the piping pipe 1 fixed to the first and second fixed units B and C And a water supply unit (D), wherein the first and second fixing units (B, C) comprise first and second support rods (20, 50) provided in the support frame (A) The first and second fixing mechanisms 30 and 60 provided on the two support rods 20 and 50 and to which the end of the pipe pipe 1 is fixed and the first and second fixing mechanisms 30 and 60 on the rear side of the first and second fixing mechanisms 30 and 60, Which are respectively connected to the ends of the pipe pipe 1 fixed to the first and second fixing mechanisms 30 and 60 and forward and rearward by the forward and backward driving means 42 and 72, And the second connection tabs 40 and 70 Wherein the water supply unit D includes a water supply pipe 82 connected to the first connection tab 40, a pressure pump 83 connected to the water supply pipe 82, And a switching valve 85 connected to the drain pipe 84. Both ends of the pipe pipe 1 are fixed to the first and second fixing units B and C, The first and second connection tabs 40 and 70 are connected to both ends of the pipe 1 in a watertight manner and supply high pressure water to the inside of the pipe pipe 1 through the first connection tab 40 So that leakage of the piping pipe 1 can be tested.

Therefore, it is very easy to test the leakage of the piping pipe 1 and the water in the piping pipe 1 is pushed by the water as the water is supplied to one side of the piping pipe 1, So that the air inside the pipe pipe 1 can be effectively discharged.

The support frame A is provided with left and right guide rails 11 extending in the left and right direction and front and rear direction guide rails 12 extending in the front and rear direction. The first and second fixing units B, C are slidably engaged with the left and right direction guide rails 11 and the front and rear direction guide rails 12 to slide the first fixing unit B in the left and right direction, So that the interval between the left and right and front and rear directions of the first and second fixing units B and C can be adjusted to fit the gap between both ends of the pipe pipe 1. [

That is, the pipe pipes 1 are bent at different lengths at opposite ends or at different intervals at opposite ends, depending on the application.

Since the first and second fixing units B and C can adjust the left and right and front and back direction intervals so as to correspond to the interval or the length of the both ends of the pipe pipe 1, There is an advantage that leakage of the piping pipe 1 can be tested.

The first and second fixing mechanisms 30 and 60 include fixing blocks 31 and 61 fixed to the first and second supporting rods 20 and 50, A pair of pushing blocks 32 and 62 slidably mounted on the fixed blocks 31 and 61 and a pair of brackets 22 and 52 provided on the first and second supports 20 and 50, And the intermediate portion is connected to the pushing blocks 32 and 62 and a cylinder connected to the other end of the pivoting arms 33 and 63 to pivot the pivoting arms 33 and 63 And fixing grooves (35, 65) for inserting the end of the pipe pipe (1, 2) are formed in the vicinity of the fixing blocks (31, 61) and the pressing blocks (32, 62) So that the force by which the cylinder mechanisms 34 and 64 expand and contract is amplified and transmitted to the pressing blocks 32 and 62. As a result, The fixing grooves 35, The opposite ends of the inserted pipe pipe 1 can be fixed strongly pressed.

Therefore, even if the cylinder mechanism (34, 64) is an air cylinder, the end of the pipe pipe (1) can be firmly fixed.

That is, in general, a hydraulic cylinder is used where strong force is required, and such a hydraulic cylinder may be contaminated by oil leakage.

However, in the case of the present invention, there is an advantage that it is not necessary to use the hydraulic cylinder by firmly fixing the end portion of the pipe pipe 1 using the air cylinder.

The drain pipe 84 is connected to a resistance generating means 87 provided on the second support 50 so as to be positioned above the second fixing device so as to supply water to the inside of the pipe pipe 1 There is an advantage that air inside the piping pipe 1 can be discharged to the outside more effectively.

That is, the pressurizing pump 83 is capable of pressurizing the water to be supplied to the pipe 1 at a very high pressure, while the flow rate of the water that can be supplied is small per hour.

Therefore, when the water is supplied to the inside of the pipe pipe 1 simply by using the pressure pump 83 without using the resistance generating means 87, the water flows simply along the inside of the pipe pipe 1 There is a problem that it is difficult to effectively discharge the air inside the piping pipe 1 to the outside.

However, in the case of this embodiment, a resistance generating means 87 for generating a fluid resistance in the drain pipe 84 is provided so that a resistance is generated when the water passes through the filter member 87d of the resistance generating means 87 The water inside the pipe pipe 1 is filled in the pipe pipe 1 by filling the inside of the pipe pipe 1 with a predetermined pressure in a state in which the opening and closing valve 85 is not locked, There is an advantage that the water can be effectively pushed out and discharged by the water.

The water supply pipe 82 is provided with an air supply means 86 for supplying high pressure air to the inside of the pipe pipe 1 through the first connection tab 40, There is an advantage that water in the piping pipe 1 can be discharged effectively by supplying water to the inside of the piping pipe 1 by using the air supply means 86 after leakage test.
