Description

Technical Field

[0001] The utility model relates to the technical field of rubber pipes, in particular to a rubber pipe pressure detection device. Background Art

[0002] Because rubber pipes have good physical and chemical properties, such as corrosion resistance, no rust, and good physical and chemical stability, they are widely used in liquid transportation. For example, pipes with larger diameters are often used for natural gas, oil or urban tap water mains. They can withstand certain pressure pipelines and have relatively thick pipe walls.

[0003] Since rubber pipes sometimes transport pressurized substances, they need to have a certain ability to resist pressure. Therefore, during rubber pipe processing, samples need to be tested for sealing and pressure. However, when existing testing equipment is used to fill air pressure tests into closed rubber pipes, the injected air pressure is sometimes too high, causing the pipe to exceed the critical value and damage the pipe that was originally within safe quality.

[0013] (3) Beneficial effects

[0014] The utility model provides a rubber pipe pressure detection device, which has the following beneficial effects:

[0015] 1. The rubber pipe pressure detection equipment is provided with a spring and a sealing bead. After the rubber pipe is clamped between two chucks, the rubber pipe is rotated into the inside of the sleeve box and the inner box. Water is placed inside the sleeve box and the inner box. Then, gas is filled into the hollow disk through an air pump. Then, air pressure is filled into the rubber pipe through a hollow shaft and a hollow tube. As the air pressure in the rubber pipe gradually increases, the air pressure gradually pushes the sealing bead to compress the spring. When the air pressure exceeds the detection value, the sealing bead moves out of the concentric tube through the compression spring, relieving the pressure inside the rubber pipe to ensure that the internal pressure of the rubber pipe does not exceed the critical value. This solves the problem that the pipe exceeds the critical value due to excessively high air pressure, causing damage to the pipe that was originally within a safe quality range.

[0016] 2. This rubber pipe pressure testing equipment is equipped with a threaded rod and a movable plate. When the wall thickness and diameter of the rubber pipe change, the critical air pressure value of the test changes. Rotating the threaded rod to engage the movable plate changes the distance that the sealing bead extends into the concentric tube, thereby changing the air pressure value required for the sealing bead to move out of the concentric tube.

Due to the cone-shaped structure of the clamp 3, the two ends of the rubber pipe can be sealed after the two clamps 3 clamp the rubber pipe. Then start the motor 17 to drive the solid shaft 7 to rotate half a circle, driving the rubber pipe to rotate to the bottom of the cross plate 5 and enter the water, so as to observe whether there is leakage after the air pressure is filled. Then use the air pump 18 to fill the hollow disk 10 with gas, and then fill the rubber pipe with air pressure through the hollow shaft 6 and the hollow tube 4. As the air pressure in the rubber pipe gradually increases, the air pressure gradually pushes the sealing bead 14 to compress the spring 12. When the air pressure exceeds the detection value, the sealing bead 14 moves out of the concentric tube 11 through the compression spring 12, and the internal pressure of the rubber pipe is relieved to ensure that the internal pressure of the rubber pipe does not exceed the critical value.
