It is an essential testing equipment for plastic pipe manufacturers and testing agencies. According to the different temperatures, pressures and hoop stresses of pipes, different parameters are input on the industrial control machine, and the high-pressure pump generates high-pressure liquid, which is transported to the sample in the medium constant temperature box by the high-pressure hose through the pressure control system to carry out long-term hydrostatic test of pipes. This equipment can fully reflect the level of product quality of the enterprise and can be controlled by digital display, LCD screen and computer.

[0003] For example, the Chinese utility model patent with publication number CN210401073U discloses "A Pipe Hydrostatic Burst Testing Machine", in which the device includes an outer box, a constant temperature water tank, a PLC controller and a high-pressure water pump; the PLC controller is arranged on the front side of the outer box, the high-pressure water pump is arranged on the right side of the outer box, the constant temperature water tank is arranged in the inner cavity of the outer box, and the constant temperature water tank and the inner cavity of the outer box are arranged to overlap; a water inlet pipe is arranged on the right side of the inner cavity of the outer box, the water inlet pipe passes through and extends to the outside of the outer box, and the water inlet pipe outside the outer box is connected to the high-pressure water pump, the test pipe is connected to the connecting flange, and then the test operation is carried out, the water pressure inside the test pipe is detected by a water pressure sensor, the test water temperature is detected by a temperature sensor, and then displayed on the PLC controller, the operation is simple and easy to operate, and the state of the pipe during the test can be observed through the observation window.

[0004] Although the above test device has certain advantages in pipe testing, it still has certain disadvantages:

[0027] Here’s how it works:

[0028] First, before use, fix the pipe to be tested with a clamp, exhaust the air inside the pipe through the vacuum device, and put it into the test box 2 to wait for the test;

[0029] Second, when in use, the control panel 5 is operated to make the control machine 4 control the detection box 2 to start testing the pipe. When the test is over, if the pipe is intact, it means that the pipe meets the requirements. If the pipe is damaged, it means that the pipe does not meet the actual standards and cannot be used. Then the broken pipe fragments need to be salvaged from the detection box 2.

[0030] Third, start the motor 61 to rotate the motor 61, and when the motor 61 rotates, the screw 62 is driven to rotate. When the screw 62 rotates, the net box 66 is driven to move upward through the fixing sleeve 67. When the net box 66 moves upward, the debris in the water is salvaged. When the net box 66 moves, it is supported by the light rod 65 so that it can rise in a stable state. When the net box 66 reaches the bottom, the salvaged debris can be taken out, and then the motor 61 is controlled to rotate the screw 62 to move the net box 66 to the bottom, which is convenient for the next use.

[0031] Fourth, after multiple uses, the water in the detection box 2 needs to be replaced and the bottom of the detection box 2 needs to be cleaned. The net box 66 needs to be taken out, and the limit plate 645 is pressed downward. When the limit plate 645 moves, the limit block 643 is driven to move. When the limit block 643 moves, the limiting effect of the card slot 644 is cancelled. Then, the fixed block 642 can be taken out from the movable slot 641, and the support block 63 is pushed upward to make the support block 63 break away from the fixation of the screw rod 62 and the light rod 65. The support block 63 is taken out from the movable slot 641, and then the net box 66 can be taken out. Finally, the water in the detection box 2 can be replaced and cleaned.

[0032] Fifth, after cleaning, place the mesh box 66 along the screw 62 and the light rod 65, place the support plate 63 into the movable groove 641, so that the support plate 63 fixes the top of the screw 62 and the light rod 65, and then place the fixed block 42. When the limit block 643 enters the movable groove 641, the movable groove 641 squeezes the inclined surface of the limit block 643, so that the limit block 643 moves downward. When the limit block 643 moves downward, the spring 646 is squeezed by the limit plate 645. When the limit block 643 moves to the bottom of the slot 644, the spring 646 loses its force and releases its elastic potential energy to pop the limit block 643 into the slot 644, so that the fixed block 642 can be fixed, and then the detection box 2 can be continued to be used for testing.

[0033] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.

[0034] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
