Description
VALVE LEAKAGE DETECTION DEVICE
[01] The present invention relates to the technical field of valve detection, more particularly to a valve leakage detection device.
[02] A valve is a pipeline accessory used to turn on and off a pipeline, control a flow direction, and regulate and control parameters (temperature, pressure, and flow rate) of a transport medium, which can be employed to control the flowing of various types of fluids, such as air, water, steam, various corrosive mediums, mud, oil, liquid metal, and radioactive mediums. According to the properties of valves, it 1s necessary to detect the tightness of the produced valve so as to put undamaged valves into service.
[03] For example, in the patent with Publication No. CN107643150A, entitled “LEAKAGE DETECTION TOOL SIMULATING REAL WORKING
CONDITION OF VALVE”, after two valve connection flanges of a valve are sealed through flange sealing heads, connectors on the flange sealing heads are communicated with external inlet and outlet pipelines to simulate a real working condition of the valve.
The valve is located in a water tank and a colored liquid passes through the valve, whereby leakage can be determined by observing the color change of the water in the water tank. However, there are shortcomings as follows during the usage process.
[04] 1. Detection of valve leakage through a colored liquid can only detect leakage holes with color changes that are visible to the naked eye. In the case that a leakage port is extremely small, when the colored liquid enters the water tank, the color of the water in the water tank does not change obviously in a short time, greatly prolonging the detection time of the valve and reducing the work efficiency.
[05] 2. The valve is connected to a center plug, a rubber sleeve and a rubber pad, so that only one specification of valve can be detected. In addition, the tightness at the connector is not good without external force, whereby the leakage at the connector is easily mistaken for the leakage of the valve, reducing the detection accuracy of the valve.
[06] Therefore, a valve leakage detection device is provided to solve the problems mentioned above.
[07] The present invention aims to provide a valve leakage detection device to solve the problem mentioned in the above background: the valve detection devices currently available on the market have low work efficiency due to low accuracy and long detection time.
[08] In order to achieve the above aim, the present invention provides the following technical solution. A valve leakage detection device includes a plurality of support columns. The plurality of support columns each have one end fixedly connected to an operating platform, the operating platform has a top surface fixedly connected to a support base and the support base has a top surface fixedly connected to an air compressor. An outer surface of one side of the air compressor is fixedly communicated with an air inlet pipe, an outer surface of one side of the air compressor is fixedly provided with a pressure gage, and an air outlet end of the air compressor is fixedly communicated with a connecting pipe. One end of the connecting pipe far away from the air compressor is fixedly communicated with a rubber sleeve.
[09] The valve leakage detection device further includes:
[10] a securing mechanism fixedly connected to the top surface of the operating platform, an outer surface of one side of the securing mechanism being fixedly connected to a hydraulic cylinder, and a bottom surface of the hydraulic cylinder being fixedly connected to the top surface of the operating platform; and
[11] a control mechanism fixedly connected to the top surface of the operating platform and mated with the rubber sleeve.
[12] Preferably, the securing mechanism includes two first chutes, and inner surfaces of the two first chutes are each slidably connected to two first slide blocks along a horizontal direction. Top surfaces of the four first slide blocks are each fixedly connected to a support rod, and ends of the four support rods far away the first slide blocks are fixedly connected to a support platform. An outer surface of one side of the support platform 1s fixedly connected to an extension plate, and an outer surface of one side of the extension plate is fixedly connected to an output end of the hydraulic cylinder.
[13] Compared with the existing technologies, the present invention has the following beneficial effects. The valve leakage detection device determines the leakage of a valve by observing the change of pressure, improving the efficiency in detecting the valve. Meanwhile, through the linkage of multiple mechanisms, the valve leakage detection device can stably detect multiple different specifications of valves and achieves a high detection accuracy.

[22] Referring to FIG. 1 to FIG. 8, the present invention provides a technical solution as follows. A valve leakage detection device includes a plurality of support columns 1. The plurality of support columns 1 each have one end fixedly connected to an operating platform 10, the operating platform 10 has a top surface fixedly connected to a support base 11, and the support base 11 has a top surface fixedly connected to an air compressor 12. An outer surface of one side of the air compressor 12 is fixedly communicated with an air inlet pipe 13, an outer surface of one side of the air compressor 12 is fixedly provided with a pressure gage 14, and an air outlet end of the air compressor 12 is fixedly communicated with a connecting pipe 15. One end of the connecting pipe 15 far away from the air compressor 12 is fixedly communicated with a rubber sleeve 16.
[23] The valve leakage detection device further includes: a securing mechanism 2 fixedly connected to the top surface of the operating platform 10. An outer surface of one side of the securing mechanism 2 is fixedly connected to a hydraulic cylinder 17, and a bottom surface of the hydraulic cylinder 17 is fixedly connected to the top surface of the operating platform 10. The securing mechanism 2 includes two first chutes 20, and inner surfaces of the two first chutes 20 are each slidably connected to two first slide blocks 21 along a horizontal direction. Top surfaces of the four first slide blocks 21 are each fixedly connected to a support rod 22, and ends of the four support rods 22 far away the first slide blocks 21 are fixedly connected to a support platform 23. An outer surface of one side of the support platform 23 is fixedly connected to an extension plate 29, and an outer surface of one side of the extension plate 29 is fixedly connected to an output end of the hydraulic cylinder 17.

A top surface of the moveable base 26 is fixedly connected to a moveable plate 27, and an outer surface of one side of the moveable plate 27 is fixedly provided with a casting polyurethane plate 28. As shown in FIG. 1 and FIG. 2, when it is needed to use the valve leakage detection device, after the hydraulic cylinder 17 is started, the extension plate 29 is driven to move, the movement of the extension plate 29 drives the support platform 23 to move, whereby driving an undetected valve to automatically move to a target position. When the valve reaches the target position and is well fixed, air is input 5 to the air compressor 12 through the air inlet pipe 13, and the air compressor 12 compresses the air so that the air is of certain pressure. When the valve is turned off and well fixed, the air compressor 12 is started, so that the air in the air compressor 12 enters the valve through the connecting pipe 15. Observe the pressure change of the pressure gage 14. When the pointer in the pressure gage 14 changes constantly, it is indicated that the valve is leaking. When the pointer in the pressure gage 14 changes and then keeps constant after a period of time, it is indicated that the valve is not leaking.
It 1s convenient to accurately detect the valve and the work efficiency is improved.

One end of the first threaded rod 44 far away from the first threaded sleeve 43 is fixedly connected to an outer surface of one side of the moveable plate 27. The connecting mechanism 5 includes a connecting rod 50. One end of the connecting rod 50 is fixedly connected to an extension rod 51, and an outer surface of one side of the extension rod 51 is fixedly connected to a plurality of limit plates 52.

As shown in FIG. 1 to FIG. 5, when the hydraulic cylinder 17 is started and drives the clamping mechanism 6 to operate, the connecting rod 50 is driven to rotate and drives the extension rod 51 to rotate. The rotation of the extension rod 51 drives the limit plates 52 to rotate. The rotation of the limit plates 53 drives the linkage plates 54 to rotate. The rotation of the linkage plates 54 drives the connecting sleeve 53 to rotate. The rotation of the connecting sleeve 53 drives the bevel gear assembly 42 to operate.
