Description

Technical Field

[0001] The utility model belongs to the technical field of metal hose air tightness detection, and in particular relates to metal hose detection equipment. Background Art

[0002] Stainless steel hose is an important component in modern industry and has many excellent properties. Stainless steel hose is made of stainless steel material, has excellent corrosion resistance, and can be used for a long time in harsh environment without rusting and damage.

[0003] It is extremely flexible and can be easily bent and twisted to adapt to various complex installation layouts and space restrictions. At the same time, stainless steel hoses also have good pressure resistance and can withstand higher pressures without deformation or rupture.

[0004] Structurally, it is usually composed of a bellows, a mesh and a joint. The bellows is the core part of the hose, responsible for bearing pressure and deformation; the mesh plays a role in strengthening and protecting the bellows; the joint is used to connect the hose to other equipment or pipelines.

[0005] Stainless steel hoses are widely used in many fields, such as petrochemical industry, machinery manufacturing, electric power communication, construction engineering, etc. In the petrochemical industry, they are used to transport various liquids and gases; in machinery manufacturing, they are used to connect the pipeline system of mechanical equipment; in the field of electric power communication, they can be used to protect cables and wires.

[0006] In short, stainless steel hoses have become an indispensable and important part of modern industrial pipeline connection and transportation systems due to their excellent performance and wide applicability;

[0007] When using stainless steel hoses, air tightness testing is required. Air tightness testing is also a safety indicator test. It is carried out under nominal pressure, and qualified products must not leak. Generally, this test can be carried out only after the pressure test is passed. The test can use dry, clean air, or nitrogen or other protective gases as the test medium as needed. The pressurizing device can use a compressor unit, air pressure generator, gas cylinder or gas cylinder group, etc. Air pressure observation is generally carried out with a barometer of level 1.5 or above or a pressure tester with the same measurement accuracy supplemented by a water tank. During the test, a plug is installed on one end of the stainless steel hose sample, and the other end is connected to the outlet of the pressurizing device. After filling with gas equal to the nominal pressure, the test piece is immersed in a water tank to remove bubbles adsorbed on the mesh cover. After the air pressure stabilizes, the pressure is maintained for a period of time (such as 10 minutes) to check whether the test piece is leaking;

[0008] However, when testing existing products, it is necessary to manually fill the hose with gas or liquid and then check whether there is any leakage at the seal. The operation process is complicated; the larger stainless steel hose has a large diameter and a long length; manual operation is relatively difficult;

[0009] To solve the above problems, a metal hose detection device is proposed in this application. Utility Model Content

[0038] A metal hose detection device includes a hydraulic station 1 and a water tank 8 arranged on one side of the hydraulic station 1. Bottom supports 9 are fixedly installed on the front and rear surfaces of the water tank 8. The device further includes a detection component A100 fixed at one end of the water tank 8 and a detection component B200 that horizontally moves on the water tank 8 through the bottom support 9;

[0039] The detection component A100 includes a fixed air inlet end 2 and an air inlet end clamping mechanism 6. The fixed air inlet end 2 is fixed above one end of the water tank 8, and an air inlet end clamping mechanism 6 is installed on the side of the fixed air inlet end 2 close to the water tank 8;

[0040] The detection component B200 includes a movable sealing end 3, and a sealing end clamping mechanism 5 is installed on the side of the movable sealing end 3 facing the water tank 8;

[0041] The air inlet end clamping mechanism 6 and the sealing end clamping mechanism 5 are on the same horizontal plane.

[0042] In this implementation: First, push the movable sealing end 3 to an appropriate position according to the length of the stainless steel hose. At this time, lower it through the safety pin assembly 4 to prevent the movable sealing end 3 from moving. Use an external crane to place the stainless steel hose at the water tank 8, and make the flanges at both ends of the stainless steel hose be placed between the air inlet clamping mechanism 6 and the sealing end clamping mechanism 5, and make the air inlet clamping mechanism 6 and the sealing end clamping mechanism 5 clamp the stainless steel hose and keep it sealed. At this time, pressurize the air inlet clamping mechanism 6 and maintain the pressure. Subsequently, make the air inlet clamping mechanism 6 and the sealing end clamping mechanism 5 descend simultaneously to sink the stainless steel hose into the water tank 8, and judge the air tightness of the stainless steel hose by observing the bubbles.

A lifting oil cylinder 51 is fixedly arranged near the end of the mounting plate 55 between the two guide shafts 52. One end of the lifting oil cylinder 51 penetrates through the surface of the movable sealing end 3 and extends above the movable sealing end 3. A clamping oil cylinder 53 is fixedly mounted at the end of the mounting plate 55 away from the water tank 8.

[0051] It should be noted that: the sealing end clamping mechanism 5 and the air inlet end clamping mechanism 6 have the same structure.

[0052] In this embodiment: the moving function of the movable sealing end 3 (moving frame) can meet the position requirements of oil pipes of different lengths to meet the compatibility of the equipment; the clamping oil cylinder 53 is used for clamping the hose flange and realizes sealing through the polyurethane sealing gasket 54; the guide shaft 52 realizes the guiding function during the overall lifting process; the lifting oil cylinder 51 provides the power during the overall lifting process.
