Description

Technical Field

[0001] The utility model relates to the technical field of hose pressure resistance detection, in particular to a multifunctional hose pressure detection device. Background Art

[0002] As a carrier for fluid transportation, hoses need to withstand certain pressures, temperatures, and media corrosion. If the hose quality is not up to standard, problems such as bursting, leakage, and aging may occur, leading to production interruptions, environmental pollution, and even safety accidents. Therefore, regular hose pressure testing is necessary. Hose pressure testing usually detects defects such as cracks, bursts, debonding, and bulging. However, the following problems may occur in actual testing:

[0003] 1. The hose has two usage scenarios: true pressure and negative pressure. Therefore, the test needs to be completed on different testing platforms, which is inconvenient;

[0004] 2. The hose diameters vary from large to small, so it is necessary to equip all the corresponding pipe joints and plugs. These parts will take up a lot of space when stored.

[0005] 3. Many pipe joints and plugs are similar in shape and size, making it difficult for operators to identify and pick them up. In addition, they need to frequently disassemble the pipe joints, which is time-consuming and labor-intensive.

[0006] 4. It is more difficult to transport and circulate large-sized hoses during pressure testing. Utility Model Content

The vacuum pump is connected to the buffer tank through the pipeline; a stepped pipe joint is fixedly connected to the side of the trolley, and the side of the buffer tank is connected to the stepped pipe joint through a rubber hose and a solenoid valve; one side of the hose is inserted into the stepped pipe joint, and the other side is fixedly connected to the solenoid drain valve through a pipe clamp and a stepped plug.

[0009] Preferably, the electric control box controls the start and stop of the vacuum pump motor and the opening and closing of the solenoid valve and the solenoid exhaust valve.

[0010] Preferably, the stepped pipe joint is designed as a hinge structure that rotates left and right.

[0011] Preferably, the pipeline structure composed of the rubber hose, solenoid valve, stepped pipe joint, hose, pipe clamp, stepped plug, and electromagnetic drain valve is symmetrically designed into multiple pipeline structures for simultaneous testing of multiple hoses.

[0012] Preferably, a storage space is provided inside the trolley, and the stepped pipe joint and the stepped plug are of a nesting doll structure. After use, the stepped pipe joint, hose, pipe clamp, stepped plug and electromagnetic drain valve are stored inside the trolley.

[0013] Compared with the closest existing technology, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. The device can be used to detect vacuum and negative pressure inside the hose, and can also be used for repeated alternating detection of internal pressure-normal pressure and negative pressure-normal pressure, which can better meet the needs of various working scenarios of the hose;

[0015] 2. The movable trolley is easy to move and occupies a small area, making it convenient for testing hoses in different locations.

[0022] The multifunctional hose pressure testing device includes a trolley 1, which facilitates testing hoses 9 stacked in various locations and facilitates the insertion and removal of stepped pipe joints 8 and stepped plugs 11 from the hoses 9. The trolley is equipped with an electrical control box 2, a vacuum pump 3, piping 4, and a buffer tank 5. The vacuum pump 3 is connected to the buffer tank 5 via piping 4 and serves as the power source for maintaining vacuum (pressure). A stepped pipe joint 8 is fixedly attached to the side of the trolley 1. The side of the buffer tank 5 is connected to the stepped pipe joint 8 via a rubber hose 6 and a solenoid valve 7. The buffer tank 5 is used for gas buffering to maintain a relatively stable vacuum (pressure) in the system. The rubber hose 6 is used to compensate for changes in hose length caused by the storage of the stepped pipe joint 8. One side of the hose 9 is inserted into the stepped pipe joint 8, and the other side is fixedly connected to the electromagnetic drain valve 12 through the pipe clamp 10 and the stepped plug 11. After the pipe clamp 10 is tightened, the airtightness between the hose 9, the stepped pipe joint 8 and the stepped plug 11 can be ensured.

[0023] Furthermore, the electric control box 2 controls the start and stop of the motor of the vacuum pump 3 and the opening and closing of the solenoid valve 7 and the solenoid drain valve 12. The user can select different detection modes such as the length of the detection time, the size of the vacuum degree (pressure), and the number of alternations.

[0024] Furthermore, the stepped pipe joint 8 is used to be inserted and vacuum (pressure) is drawn inside. The stepped pipe joint 8 is designed as a hinge structure to facilitate its left and right rotation, and the detection method is more flexible. After use, it can be folded into a length close to that of the trolley, occupying a small space.

[0026] Furthermore, the electromagnetic drain valve 12 is opened to bring the interior of the hose to normal pressure. When used in conjunction with the electromagnetic valve 7, the hose can be subjected to alternating tests of vacuum-normal pressure and pressure-normal pressure.

[0027] Furthermore, the pipeline structure composed of the rubber hose 6, the solenoid valve 7, the stepped pipe joint 8, the hose 9, the pipe clamp 10, the stepped plug 11, and the solenoid drain valve 12 is symmetrically designed as multiple pipeline structures, which are used for simultaneous detection of multiple hoses 9, thereby improving the work efficiency of hose detection.

[0028] Furthermore, a storage space is provided inside the trolley 1, and the stepped pipe joint 8 and the stepped plug 11 are a nesting doll structure. After use, the stepped pipe joint 8, hose 9, pipe clamp 10, stepped plug 11, and electromagnetic drain valve 12 are stored inside the trolley 1, which is convenient to store.

[0029] Furthermore, the vacuum pump 3, the pipeline 4, and the buffer tank 5 can be integrated with the same type of products.

[0030] Furthermore, the trolley 1 is designed with both a vacuum pump 3 and an air compressor, and vacuum and pressure are obtained through independent pipelines or switching pipelines and used for hose testing, which is also within the scope of protection of this patent.
