Description

Technical Field

[0001] The utility model relates to the technical field of valve detection, in particular to a valve air tightness detection device. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion, or overflow pressure relief. Valve air tightness refers to the sealing performance between the valve disc and the valve seat after the valve is closed. If the valve air tightness is not good, it will cause medium leakage and affect the normal operation of the pipeline system. The valve is leaking by measuring the internal and external air tightness levels of the valve. The existing valve air tightness detection equipment is placed for easy placement during the detection process. As the air tightness and penetration tests are carried out, it is easy for parts to be misplaced due to pressure, which requires them to be disassembled and repeatedly adjusted, reducing the overall detection performance. Therefore, we have proposed a valve air tightness detection equipment to solve the above problems. Utility Model Content

[0003] In order to overcome the problem that the valve air tightness detection equipment is easily placed, parts are easily misplaced due to pressure during air tightness and penetration tests, which requires disassembly and repeated adjustment operations, thereby reducing the overall detection performance.

[0005] Preferably, an airtight cover and an airtight box are snapped together to seal and protect against airtight water, liquid and gas tests. When fluctuations occur in the airtight water, liquid and gas tests, the floating test module can perform detection. The airtight cover corresponds to the mounting assembly, and the valve body can be installed in a bidirectionally positioned manner while maintaining overall stability. When performing detection, multiple sets of floating feathers and floating ropes are installed using the docking holes on the horizontal plate. As the valve is ventilated and liquid is passed through, leakage will flow outward when it occurs. Since the floating feathers and floating ropes are made of lightweight materials, the internal electrical signal device and vibration sensor can continuously provide feedback to the background, and synchronize with the visual detector for observation to improve the overall detection performance.

[0006] Preferably, a shock-absorbing plate is provided at the lower end of the airtight box, and shock-absorbing brackets are provided at the corners around the lower end of the shock-absorbing plate. A visual detector is provided inside the airtight box near the connection box, and a liquid level column is provided on the side of the airtight box away from the visual detector.

A limiting ring groove is provided around the inner side of the positioning ring, and an inner ring is provided at the lower end of the positioning ring. A positioning hole is provided around the outer side of the inner ring at the lower end of the airtight cover. A plurality of groups of temperature sensors are distributed near the edge of the lower end of the airtight cover, and an airtight card block is provided at the bottom edge of the airtight cover to detect the interior using the temperature sensor.

[0010] Preferably, the floating test module includes a horizontal plate, a conical column and a floating rope. A docking hole is opened along the edge of the horizontal plate, a conical column is provided at the center of the docking hole, a floating rope is wrapped around one end of the conical column, and an electric signal device and a vibration sensor are provided inside the floating rope.

[0011] Preferably, the installation assembly includes an installation chuck, a connecting block, a stepped sleeve and a sealing sleeve. A connecting block is arranged around the upper part of the installation chuck, a plug-in hole is arranged between two groups of connecting blocks, a stepped sleeve is arranged in the center of the installation chuck, and a sealing sleeve is arranged at the lower end of the stepped sleeve. The sealing sleeve is used to facilitate the connection of the drainage and exhaust pipes.

[0012] Beneficial effects of the utility model:

[0013] 1. According to the previous simple placement, when conducting airtightness and penetration tests, parts are prone to pressure dislocation, which requires removal and repeated adjustment. The difference is that the airtight box and the connection box are integrally formed to position and place the valve cover and maintain overall stability. The airtight cover and the airtight box are interlocked and sealed to protect the airtight water and gas tests. When the airtight water and gas tests produce fluctuations, the floating test module can be used for detection. The airtight cover corresponds to the installation component, which can be used to perform bidirectional positioning and installation of the valve body and maintain overall stability. When testing, multiple sets of floating feathers and floating ropes are installed using the docking holes on the horizontal plate. As the valve is ventilated and liquid is passed, leakage will flow outward. Since the floating feathers and floating ropes are made of lightweight materials, the internal electrical signal device and vibration sensor can continuously provide feedback to the background, and synchronize with the visual detector for observation to improve the overall detection performance.

[0014] 2. When installing, use the stepped sleeve to dock with one end of the valve body, and use the installation chuck and the plug hole to perform installation positioning. The first driver drives the first sleeve to slide along the first slide rail to the corresponding position of the valve cover, and uses the magnetic sleeve to clamp the corresponding position on the valve cover to form a positioning connection. When performing internal testing, the rotator drives the rotating disk to rotate the valve cover with the magnetic sleeve to open and close it for easy coordination and detection. The second driver drives the second sleeve to slide along the second slide rail to the corresponding position of the valve stem, and uses the tension bolt to adjust the direction of the extension column so that the magnetic clamping ring can clamp the valve stem in position to increase stability.
