Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessel detection, in particular to a leakage detection device for pressure vessels. Background Art

[0002] Pressure vessels refer to closed equipment that contains gas or liquid and bears a certain pressure. Leakage of pressure vessels is a serious safety accident that may lead to serious consequences such as fire, explosion and poisoning. Pressure vessel leakage detection is crucial to ensure the safe operation of pressure vessels.

[0003] Most existing pressure vessel detection equipment immerses the pressure vessel filled with gas in water and observes the bubbles in the water to determine whether there is a leak. However, it is impossible to determine the specific location of the pressure vessel leakage point, which is inconvenient for maintenance and reduces the detection effect. Utility Model Content

[0004] The utility model aims to solve the defect in the prior art that the existing pressure vessel leakage detection equipment cannot determine the specific location of the pressure vessel leakage point, and proposes a pressure vessel leakage detection equipment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A leakage detection device for pressure vessels, comprising an installation box for placing a pressure vessel body, an air pipe is inserted at one end of the pressure vessel body, an air valve is provided on the air pipe, a pressure gauge is inserted at the other end of the pressure vessel body, two support frames are fixedly connected between the inner walls on both sides of the installation box, the pressure vessel body is placed on the support frames, a driving wheel is rotatably embedded at the top of the support frames, a rotating shaft is inserted between the two driving wheels, a water collecting block is fixedly connected to the inner wall at the bottom of the installation box, two electric push rods are fixedly connected to the top of the water collecting block, a detection box is fixedly connected to the top between the two electric push rods, observation windows are embedded on both sides of the detection box, and a water inlet pipe is inserted at the top of the detection box.

[0007] Furthermore, a motor is fixedly connected to the top of the water collecting block, and an output end of the motor is fixedly connected to one end of the rotating shaft.

[0008] Furthermore, a plurality of drainage holes are provided at the bottom of the support frame.

[0009] Furthermore, a plurality of driven wheels are rotatably embedded on the top of the support frame.

[0010] Furthermore, a drainage pipe is plugged into one side of the installation box.

[0011] Furthermore, two sealing strips are clamped on the bottom of the detection box.

[0012] The beneficial effects of the utility model are:

[0013] 1. Open the gas valve and input gas into the pressure vessel from the gas pipe. Then, observe the value of the pressure gauge. If the value of the pressure gauge drops, it indicates that the gas in the pressure vessel is leaking, which facilitates the detection of the pressure vessel.

[0014] 2. The detection box is stuck on the pressure vessel body by the electric push rod. Then, water is input into the detection box from the water inlet pipe. The water in the detection box contacts the pressure vessel body. Then, the surface of the pressure vessel body in contact with water is observed through the observation window to see if there are bubbles. The leakage position of the pressure vessel body is observed by the position of the bubbles for subsequent maintenance.

[0015] 3. By rotating the driving wheel driven by the motor, the pressure vessel body is driven to rotate, thereby adjusting the detection position of the pressure vessel body and improving the comprehensiveness of the pressure vessel detection. BRIEF DESCRIPTION OF THE DRAWINGS
