Description

Valve test device {DEVICE FOR TESTING VALVE}

The disclosure disclosed herein relates to a valve test apparatus, and in particular, a valve capable of accurately and quickly mounting valves of various sizes in testing a valve performance by inspecting a leak pressure while injecting high pressure water into a valve. It relates to a test device.

Unless otherwise indicated herein, the contents described in this section are not prior art to the claims of this application, and inclusion in this section is not admitted to be prior art.

The valve is installed on the pipe and performs a function of controlling the transfer amount of fluid such as water, oil, and gas.

In order to prevent the leakage of fluid due to defects occurring during the processing and assembly of the valve itself after installing the valve, when the production of the valve is completed, the valve test device is used to perform the pressure test of the valve before shipment. do.

The valve test apparatus performs quality inspection of the valve by connecting test pipes to both ends of the valve and generating pressure in the valve through the test pipe. The pressure is checked through the pressure gauge, and when the set pressure is reached, the hydraulic valve is opened. After closing, observe the pressure change of the pressure gauge for a certain period of time to determine whether the valve is leaking or not.

Here, as an example of the valve test apparatus, Korean Utility Model Registration No. 20-0429474, "Automatic valve hydraulic test apparatus (October 17, 2006)" has been disclosed.

The valve test apparatus of the above document comprises a valve clamp means 10, a hydraulic pump 20, a water supply valve 30, a pressure sensor 40 and a controller 50 as shown in FIG. .

The valve clamp means 10 includes a fixed flange 12 and the movable flange 14, the fixed flange 12 is made of a hollow pipe shape is kept airtight in close contact with one end of the valve (V), The movable flange 14 is installed to face the fixed flange 12 so as to move forward and backward in a direction toward the fixed flange 12 by the operation of the pressure cylinder 14a at a position corresponding to the fixed flange 12. In close contact with the other end of the valve V, airtightness is maintained.

At this time, the movable flange 14 is driven forward and backward to the fixed flange 12, the clamping while pressing the valve (V) or unclamping while being spaced apart from the valve (V).

In addition, the hydraulic pump 20 supplies water stored in the water tank T through the high pressure hose 22 connected to the movable flange 14 to the inside of the valve V, and moves through the high pressure hose 22. It is connected to communicate with the inside of the flange 14 and the operation is controlled by the controller 50.

When the water pressure pump 20 transfers the water stored in the water tank T through the high pressure hose 22 during the ON operation, and the water pressure set in the valve V acts, the pressure sensor 40 to be described later detects this and turns OFF. In operation, the water supply valve 30 is shut off and the water pressure inside the valve V is kept constant as the transfer of water through the high pressure hose 22 is closed.

Then, the water supply valve 30 is installed on the high pressure hose 22, to control the transfer of water supplied into the valve (V), the pressure sensor 40 is installed on the high pressure hose 22, (V) measuring the water pressure inside, the control unit 50 controls the water supply valve 30 when the water pressure of the pressure sensor 40 reaches the set pressure to block the transfer of water through the high-pressure hose (22). .

On the other hand, the controller 50 controls the operation of the hydraulic pump 20, the water supply valve 30 and the pressure sensor 40, and after the leak pressure inspection of the valve (V) is completed, the movable flange 14 and the valve ( V) The drain valve 60 is provided to recover the water remaining inside the water tank T through the drain hose H1.

In addition, when an allowable pressure or more is applied to the valve V or a problem occurs in the system, a safety valve 70 is provided to discharge the high pressure water to the water tank T through the auxiliary hose H2.

Therefore, in the test of the valve performance by inspecting the leakage pressure in the state of injecting high pressure water into the valve, when the high pressure water is injected, the control unit automatically operates the hydraulic pump and the water supply valve to supply the high pressure water based on the set pressure. As a result of the control, the water pressure in the valve is kept equal to the set pressure so that the leak pressure test is performed.

However, the conventional valve test apparatus including the valve test apparatus described above has a problem in that it is not possible to mount valves of various sizes having different flange diameters of the valve.

Some devices have been developed and used to clamp the valve using the clamping means provided radially spaced apart from each other in order to supplement the above problems, but there is a safety problem because only a portion of the valve frame is clamped.

In addition, since the valve test inspection is made in a specific position where the device is installed, there are disadvantages in that various problems such as cost, time, and breakage due to valve movement occur.
