Description

Technical Field

[0001] The utility model belongs to the technical field of pressure boosting devices for testing machines, and particularly relates to a pressure boosting device for a multi-station water pressure testing machine. Background Technique

[0002] The water pressure testing machine is mainly used for water pressure tests, pressure resistance tests, burst tests, static pressure tests, and flexure tests of various oil pipes, hoses, and rubber hoses. The pipeline system adopts non-welded connections, the test fluid system and the driving fluid system are separated, which is convenient for test temperature control and diverse test media. There are three different control methods to choose from: manual control, PLC control, and computer control. A high-speed sampling card is used to sample test data to meet different installation methods of the test pieces for hoses.

[0003] When the current water pressure testing machine is in use, by setting multiple test heads, it is convenient to conduct water pressure tests on multiple cast pipes. And currently, water is introduced into the interior of the cast pipe to conduct a water pressure test on the cast pipe. Currently, in order to improve the test effect, gas is re-introduced into the interior of the cast pipe into which water is injected, thereby increasing the pressure inside the cast pipe. However, both the current water guiding pipe and the gas guiding pipe control the opening and closing of the pipeline through separate valve bodies, and the operation of the valve bodies is controlled by corresponding set programs. The setting of multiple valve bodies increases the use cost of the device on the one hand. On the other hand, multiple valve bodies are controlled by multiple programs, and multiple programs cooperate with each other. After one of the programs fails, other programs all go wrong, thereby increasing the failure rate of the valve bodies. Moreover, the separate setting of multiple valve bodies also increases the maintenance difficulty of the device. Therefore, a pressure boosting device for a multi-station water pressure testing machine is provided. Content of the Utility Model

[0028] The output end of the driving motor 401 is connected with a first synchronous wheel 402 through a coupling.

[0029] Based on the above embodiments, the rotation of the output end of the drive motor 401 drives the rotation of the first synchronous pulley 402. The rotation of the first synchronous pulley 402 drives the rotation of the rotating rod 403. The rotation of the rotating rod 403 can drive the rotation of the first bevel gear 404. The rotation of the first bevel gear 404 drives the rotation of the second bevel gear 405. The rotation of the second bevel gear 405 can drive the rotation of the rotating column 406 and the first valve body 407. The rotation of the first valve body 407 can be used to open and close the first connecting pipe 4061.

[0030] On this basis, the outer wall of the first synchronous pulley 402 is engaged with a synchronous belt 4021. The inner wall of the synchronous belt 4021 is engaged with a second synchronous pulley 4022. The second synchronous pulley 4022 is located above the first synchronous pulley 402.

[0031] Based on the above embodiments, the rotation of the first synchronous pulley 402 can drive the rotation of the synchronous belt 4021. The rotation of the synchronous belt 4021 can drive the rotation of the second synchronous pulley 4022. The rotation of the second synchronous pulley 4022 can drive the rotation of the connecting column 408. The rotation of the connecting column 408 drives the rotation of the second valve body 409. The rotation of the second valve body 409 can be used to open and close the second connecting pipe 4081.

[0032] The bottom end of the air pump 3 is fixedly provided with a base 301 through bolts. The bottom end of the base 301 is fixedly connected to the top end of the workbench 1 through bolts. One end of the water pump 2 is fixedly connected to a liquid guide pipe 201. The bottom end of the workbench 1 is fixedly provided with a water tank 202 through bolts. The water tank 202 is connected to the liquid guide pipe 201. The water tank 202 is used for storing water. The base 301 is used for supporting the air pump 3. The liquid guide pipe 201 is used for guiding the water in the water tank 202 into the pressurizing pipe 1011.

[0033] The outer wall of the connecting column 408 is rotationally connected with a support seat 4082 through a bearing. One side of the support seat 4082 is fixedly connected to one side of the base 301 through bolts. The support seat 4082 is used for supporting the connecting column 408, and the support seat 4082 is used for ensuring the stability of the rotational force transmission of the connecting column 408.

[0034] Working principle: First, place the cast pipe to be tested between the fixed seat 101 and the moving seat 102. Then, control the horizontal movement of the moving seat 102 to clamp and fix the cast pipe through the fixed seat 101 and the moving seat 102. After that, control the water pump 2 to work. The water pump 2 introduces the water in the water tank 202 into the first connecting pipe 4061 through the liquid guiding pipe 201. The water in the first connecting pipe 4061 is introduced into the pressure increasing pipe 1011. As the amount of water in the pressure increasing pipe 1011 increases, the water in the pressure increasing pipe 1011 enters the fixed seat 101 and the interior of each cast pipe to be tested. The increase in the amount of water increases the water pressure introduced into the cast pipe interior.

[0035] Secondly, after the water in the cast pipe is introduced, control the output end of the driving motor 401 to rotate. The rotation of the driving motor 401 drives the first synchronous wheel 402 to rotate. The rotation of the first synchronous wheel 402 drives the rotating rod 403 to rotate. The rotation of the rotating rod 403 drives the first bevel gear 404 to rotate. The rotation of the first bevel gear 404 drives the second bevel gear 405 to rotate. The rotation of the second bevel gear 405 drives the rotating column 406 to rotate. The rotation of the rotating column 406 drives the first valve body 407 to rotate. The first valve body 407 rotates and closes the first connecting pipe 4061. At this time, the water in the pressure increasing pipe 1011 cannot flow back. While the first synchronous wheel 402 rotates, it drives the synchronous belt 4021 to rotate. The rotation of the synchronous belt 4021 drives the second synchronous wheel 4022 to rotate. The rotation of the second synchronous wheel 4022 drives the connecting column 408 to rotate. The rotation of the connecting column 408 drives the second valve body 409 to rotate. The second valve body 409 rotates and opens the second connecting pipe 4081. At this time, the air pump 3 works and introduces gas into the pressure increasing pipe 1011. The gas is introduced into the interior of the pressure increasing pipe 1011 and increases the air pressure in the pressure increasing pipe 1011 and the cast pipe interior.

[0036] Finally, the first valve body 407 can be rotated to open and close the first connecting pipe 4061, and the rotation of the second valve body 409 can be driven by the same power source. The rotation of the second valve body 409 can open and close the second connecting pipe 4081. Compared with the traditional setting of multiple valve bodies, on the one hand, the use cost of the device is reduced, and on the other hand, through the linkage setting of the first valve body 407 and the second valve body 409, the situation of liquid backflow when increasing the air pressure in the pressure increasing pipe 1011 is avoided.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
