Description

A vehicle-mounted online inspection device for hoses Technical Field

[0001] This utility model relates to the field of hose testing technology, and in particular to a vehicle-mounted online testing device for hoses. Background Technology

[0002] Tanker trucks include oil tankers and vehicles transporting hazardous chemicals. Oil tankers transport flammable and explosive petroleum products. If the hoses are not properly sealed, leaks can cause fires, explosions, and other serious safety accidents, threatening lives and property. Sealing and pressure testing of hoses ensures safe operation within specified pressure ranges, preventing hose rupture or seal failure due to overpressure. For example, if the pressure on the hose exceeds its rated value during filling or unloading, rupture and leakage are likely. Oil tanker hose leaks cause oil evaporation and leakage, polluting the environment. Harmful substances in the oil can pollute soil, water sources, and air, affecting the ecological balance. For example, harmful substances such as benzene in gasoline volatilize into the air, forming photochemical smog that harms human health; leaked oil seeps into the ground, polluting groundwater. Traditional hose sealing tests require removing the hose from the tanker and sending it to a specialized testing agency, a cumbersome process that involves repeated disassembly and reassembly, is time-consuming and labor-intensive, and reduces work efficiency. Summary of the Invention

[0003] Based on the above, the purpose of this utility model is to provide a vehicle-mounted online testing device for infusion tubing, enabling rapid and convenient testing of infusion tubing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0027] As shown in Figures 1 and 2, this embodiment provides an on-board online detection device for a flexible hose, suitable for tank trucks, such as oil tankers. The tank truck includes a tank 1, which has an inlet and an outlet. A connector 2 is provided at the inlet, preferably an HYJ63 connector, which connects to an external injection pipe to inject liquid, such as gasoline, into the tank 1. Specifically, the on-board online detection device for the flexible hose includes a gas source assembly 3 and a delivery hose 4. The gas source assembly 3 is used to pump a detection gas, such as air. The delivery hose 4 has a first port and a second port. The first port is connected to or disconnected from the outlet of the tank truck and from or disconnected from the gas source assembly 3. The second port is detachably connected to the connector 2, which is equipped with a throttle valve 5. The infusion hose 4 is connected to the outlet of the liquid tanker through its first port, and the second port is used to output liquid. When it is necessary to test the sealing performance of the infusion hose 4, simply disconnect the first port from the outlet of the liquid tanker and connect it to the gas source assembly 3. Connect the second port to the connector 2, close the throttle valve 5, and pump the test gas through the gas source assembly 3. This allows observation of whether there is any leakage in the infusion hose 4, thereby achieving the sealing performance test of the infusion hose 4. It also allows observation of the condition of the infusion hose 4 under a certain pressure, achieving constant pressure testing of the infusion hose 4. There is no need to remove the infusion hose 4 from the liquid tanker and take it to a specialized testing agency for testing, enabling real-time and rapid testing, saving testing time and improving work efficiency. This means that by controlling the on / off state of the first port of the infusion hose 4 and the outlet and the gas source component 3, and connecting the second port to the connector 2 with the throttle valve 5, it is possible to achieve the detection of the infusion hose 4 without repeatedly disassembling and assembling the infusion hose 4 or using additional testing equipment. This is convenient and quick, and the infusion hose 4 can be tested on the tanker truck, avoiding the tanker truck being unusable for too long due to testing, thus improving work efficiency.

[0028] In this embodiment, a pressure-stabilizing valve 10 is provided at the second port of the infusion tubing 4. The pressure-stabilizing valve 10 is detachably connected to the connector 2 or used to connect to an external infusion device. The pressure-stabilizing valve 10 effectively stabilizes the outlet pressure of the second port, preventing pipeline damage caused by pressure fluctuations.

[0029] Preferably, a pressure gauge 6 is provided on the connector 2. The pressure gauge 6 detects the air pressure in the infusion tubing 4 in real time, so as to more accurately detect whether the infusion tubing 4 is leaking air. It can also perform constant pressure detection on the infusion tubing 4. The gas source component 3 pumps the detection gas. After the pressure gauge 6 detects that the preset air pressure has been reached, the gas source component 3 is turned off to detect the infusion tubing 4 under the preset air pressure.

[0030] Preferably, the gas source component 3 is detachably mounted on the tank truck. This facilitates maintenance and replacement, and also allows for selection of assembly or disassembly based on actual usage needs. For example, the gas source component 3 is detachably mounted via a mounting bracket, which is fixed to the tank truck with bolts, facilitating assembly and disassembly and providing good structural stability.

[0031] Furthermore, the first port is connected to the liquid outlet of the tanker truck via the first pipe 7. The liquid outlet of the tanker truck is equipped with a control valve. The gas source assembly 3 is connected to the first pipe 7 via the second pipe 8, and a shut-off valve 9 is installed in the second pipe 8. By controlling the opening and closing of the liquid outlet via the control valve and the opening and closing of the second pipe 8 via the shut-off valve 9, the working state or detection state of the infusion hose 4 can be switched. When detection is required, the control valve is closed, the shut-off valve 9 is opened, the throttle valve 5 is closed, the gas source assembly 3 is started, and in conjunction with the pressure gauge 6, leakage detection and pressure detection of the infusion hose 4 are initiated.

[0032] In this embodiment, the liquid tank 1 is an oil tank, and the control valve is a PCV (crankcase forced ventilation) valve 11. Specifically, a PCV valve 11 is installed at the outlet of the oil tank. The PCV valve 11 has a pneumatic inlet and a feedback port. The oil outlet of the PCV valve 11 is connected to the first port of the infusion hose 4 via a first pipe 7. A Venturi tube 12 is installed in the first pipe 7, and the Venturi tube 12 is connected to the feedback port of the PCV valve 11 via a third pipe. A pressure gauge is installed in the third pipe. The oil flow rate is accurately detected and controlled through the Venturi tube 12 and the pressure gauge. It should be noted that the PCV valve 11 is a relatively mature existing technology, therefore, it will not be described in detail here.

[0033] Furthermore, the gas source assembly 3 includes an air compressor 31, which is connected to the first pipe 7 via a second pipe 8. Gas is pumped by the air compressor 31; when testing is required, the shut-off valve 9 is opened and the air compressor 31 is turned on.

[0034] Specifically, the gas source assembly 3 also includes a pressure control valve 32, which is installed in the second pipeline 8. The pressure control valve 32 controls the gas pressure in the second pipeline 8 to ensure that the detection pressure reaches the preset pressure. By observing and recording the control pressure of the pressure control valve 32 and the pressure value of the pressure gauge 6 at the connector 2, the sealing test and constant pressure test of the infusion tubing 4 are achieved, ensuring the accuracy and safety of the testing process.

[0035] In this embodiment, the source component also includes a gas-liquid separator 33, which is disposed in the second pipe 8 to prevent moisture from entering the infusion tubing 4 and causing contamination.

[0036] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
