Abstract
Description
Technical Field
[0001] The utility model relates to the field of valve experimental equipment, in particular to a valve bidirectional air tightness testing device. Background Art
[0002] Valves are control components in fluid delivery systems, used to open and close pipelines, control flow direction, and adjust and control parameters of the conveying medium (such as temperature, pressure, and flow).
[0003] After valve production and processing, the finished product needs to be tested for air tightness to ensure product quality. However, during testing, existing equipment generally flushes gas into the valve and then into soapy water. If bubbles are generated, it means that the air tightness is insufficient. After the test is completed, the valve needs to be cleaned to remove the soapy water. This increases the number of steps after testing and reduces the test efficiency. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

Then start the motor, which drives the screw to rotate, so that the slider moves along the inside of the slide groove until the plug moves to the inside of the box and blocks the positions on both sides of the valve. At this time, the extrusion plate squeezes the rubber gasket to seal the outside of the hole groove, so that the box is in a closed state to prevent interference from the external environment. Then start the air compressor to inject air into the valve. The one-way valve prevents gas backflow. After gas is injected, the pressure gauge displays the value. Stop the air compressor. If the valve is not airtight, the pressure gauge value gradually decreases. Then close the valve and use the air compressor to make the pressure gauge values on both sides different. Then observe the values. If the airtightness is insufficient, the values on both sides change. In this way, the two-way air tightness of the valve can be tested.
[0006] Preferably, the fixing mechanism includes an electric push rod and a clamping plate. The electric push rod is fixed on the inner wall of the box. Two electric push rods are provided, which are symmetrically fixed on the upper and lower sides of the box. The clamping plate is fixed on one side of the electric push rod. When in use, the electric push rod is started to drive the clamping plate to move, so that the valve on the upper end of the clamping plate can be clamped and fixed, thereby facilitating the valve fixation detection work.
[0007] Preferably, the screw rod is movable and penetrates into the interior of the slide groove, and the screw rod is a forward and reverse screw rod.
[0008] Preferably, the door panel is a transparent panel, which facilitates observation of the interior of the box.
[0009] Preferably, the slider is sleeved on the outside of the screw rod through a thread, and two sliders are provided, symmetrically arranged on both sides of the screw rod.
[0010] Preferably, an air injection hole is provided inside the plug.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The utility model places the valve in the position of the fixing mechanism, clamps and fixes it through the fixing mechanism, and then starts the motor. The motor drives the screw to rotate, so that the slider moves along the inside of the slide groove until the plug moves to the inside of the box body and blocks the positions on both sides of the valve. At this time, the extrusion plate squeezes the rubber gasket to seal the outside of the hole groove, so that the box body is in a closed state to prevent interference from the external environment. Then the air compressor is started to inject air into the valve. The one-way valve prevents gas from flowing back. After the gas is injected, the pressure gauge displays a value. Stop the air compressor. If the valve is not airtight, the pressure gauge value will gradually decrease. Then the valve is closed, and the air compressor is used to make the values of the pressure gauges on both sides different. Then the values are observed. If the airtightness is insufficient, the values on both sides change. In this way, the two-way air tightness of the valve can be tested.

A hole groove 12 is opened on both sides of the box body 2, and a slider 7 is sliding inside the slide groove 3. The slider 7 is connected to the outside of the screw 6 through a threaded sleeve. There are two sliders 7, which are symmetrical on both sides of the screw 6. An air compressor 11 is fixed to the top of the slider 7 through a mounting bracket, and a one-way valve 14 is fixed to the output end of the air compressor 11 through a connecting valve. A pressure gauge 13 is installed on one side of the one-way valve 14 through a pipeline, and a plug 10 is installed on one side of the pressure gauge 3 through a pipeline. An air injection hole is opened inside the plug 10, and the pressure gauge 3 is installed on the outside of the pipeline The extrusion plate 16 is welded around and fixed, and a rubber pad 15 is glued and fixed on one side of the extrusion plate 16. When in use, the valve is placed in the position of the fixing mechanism and clamped and fixed by the fixing mechanism. Then, the motor 4 is started, and the motor 4 drives the screw 6 to rotate, so that the slider 7 moves along the inside of the slide groove 3 until the plug 10 moves to the inside of the box body 2 and blocks the positions on both sides of the valve. At this time, the extrusion plate 16 squeezes the rubber pad 15 and seals the outside of the hole groove 12, so that the box body 2 is in a closed state to prevent interference from the external environment. Then start the air compressor 11 to inject air into the valve, and the one-way valve 14 prevents gas backflow. After gas is injected, the pressure gauge 13 displays a value, and stop the air compressor 11. If the valve is not airtight, the value of the pressure gauge 13 gradually decreases.

[0021] Working principle: The valve is placed in the position of the fixing mechanism and clamped and fixed by the fixing mechanism. Then the motor 4 is started. The motor 4 drives the screw 6 to rotate, so that the slider 7 moves along the inside of the slide groove 3 until the plug 10 moves to the inside of the box body 2 and blocks the positions on both sides of the valve. At this time, the extrusion plate 16 squeezes the rubber pad 15 and seals the outside of the hole groove 12, so that the box body 2 is in a closed state to prevent interference from the external environment. Then the air compressor 11 is started to inject air into the valve. The one-way valve 14 prevents the gas from flowing back. After the gas is injected, the pressure gauge 13 displays a value. Stop the air compressor 11. If the valve is not airtight, the value of the pressure gauge 13 gradually decreases. Then the valve is closed. Then the air compressor 11 is used to make the values of the pressure gauges 13 on both sides different. Then observe the values. If the airtightness is insufficient, the values on both sides change. In this way, the two-way air tightness of the valve can be tested. When in use, the electric push rod 9 is started to drive the clamping plate 8 to move, so that the valve on the upper end of the clamping plate 8 can be clamped and fixed, thereby facilitating the fixed detection of the valve.
