Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel tank sealing test, specifically a sealing test tool for an oil-filled stainless steel tank. Background Technology

[0002] In many industrial sectors, such as petrochemicals, food processing, and machinery manufacturing, stainless steel oil tanks are key equipment for storing and transporting various types of oil. Their sealing performance is of paramount importance. If the seal fails, oil leakage will not only waste resources but may also cause serious consequences such as environmental pollution and safety accidents. Therefore, it is necessary to conduct sealing tests on stainless steel oil tanks.

[0003] Existing sealing tests mostly use the positive pressure method to test the sealing of stainless steel tanks. However, the testing tools are not convenient to carry and move, especially when testing multiple large stainless steel tanks in different locations, which increases the difficulty and cost of operation. Therefore, it is necessary to propose a sealing test tool for oil-filled stainless steel tanks. Utility Model Content

[0004] The purpose of this invention is to provide a sealing test tool for stainless steel oil tanks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing test tool for an oil-filled stainless steel tank, comprising a base, a support leg fixedly installed at the lower end of the base, a pull rod fixedly installed at the lower end of the base, an air compressor fixedly installed at the upper end of the base, a side plate fixedly installed on the left side of the base, a support one fixedly installed on the left side of the side plate, an axle fixedly installed on the inner side of the support one, a large wheel rotatably installed on the front side of the axle, a support two fixedly installed on the left side of the side plate, a reinforcing beam fixedly installed on the left side of the support two, and an installation plate fixedly installed on the left side of the reinforcing beam. A caster wheel is fixedly installed on the left side. A pipe rack is fixedly installed on the right side of the side plate.

A pressure gauge is fixedly installed at the upper end of the four-way pipe. A connecting air pipe is fixedly installed at the rear end of the four-way pipe. A flexible hose is threadedly connected to the rear end of the connecting air pipe. A pressure tester is threadedly connected to the end of the flexible hose away from the connecting air pipe. An oil cap is fixedly connected to the lower end of the pressure tester. A stainless steel groove body is provided at the lower end of the oil cap.

[0006] Preferably, four legs are fixedly installed at the lower end of the base, and two supports are fixedly installed on the left side of the side plate.

[0007] Preferably, large wheels are rotatably mounted on both the front and rear ends of the axle, and two omnidirectional wheels are fixedly mounted on the left side of the mounting plate.

[0008] Preferably, the reinforcing beam is perpendicular to the first support, and the second support is fixedly installed between the reinforcing beam and the side plate.

[0009] Preferably, the air supply pipe is connected between the air compressor and the four-way pipe, and the four-way pipe is connected between the air supply pipe and the connecting pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This oil-filled stainless steel tank sealing test tool, with its support legs, pull rod, large wheels, and casters at the bottom of the base, allows operators to easily move the entire test tool to different locations next to the stainless steel tank by pulling the pull rod and using the large wheels and casters. The tool can then be placed horizontally on the ground with the support legs touching the ground. This allows for convenient testing of both large and small stainless steel tanks in different locations, greatly reducing operational difficulty and cost, improving testing efficiency, and reducing labor intensity. A check valve on the outside of the air supply pipe prevents backflow of gas, ensuring air pressure stability and testing safety. A pressure relief valve fixedly installed at the bottom of the four-way pipe automatically releases pressure when it is too high, effectively preventing damage to the test tool and stainless steel tank due to abnormal pressure, further enhancing testing safety.

[0014] 2. This stainless steel oil tank sealing test tool features a pipe rack fixed to the right side of the side plate, which facilitates the organization and fixation of the air pipes, making the pipeline layout of the entire device neat and orderly. This avoids operational inconvenience caused by air pipe tangling and also helps protect the air pipes, extending their service life. The threaded connection between the two ends of the hose and the connecting air pipe and pressure test connector not only facilitates installation and disassembly but also ensures the sealing of the connection, guarantees the stability of pressure transmission, and improves testing efficiency.
