Description

Technical Field

[0001] The utility model relates to the technical field of regulating supply pressure, in particular to a pressure-pressing device capable of quickly regulating supply pressure. Background Art

[0002] A pressure test device is a device used to perform pressure tests on various containers, piping systems or equipment. The device mainly uses a power source (such as an electric pump or a pneumatic pump) to generate liquid (such as water, oil) or gas (such as nitrogen, compressed air) at a certain pressure. These media are driven by the device and transported into the target object to be tested. Its purpose is to verify the strength and sealing of the target object.

[0003] The adjustment mechanism of the pressure test device is relatively complicated. When the supply pressure needs to be changed in a short period of time, such as adjusting from a lower pressure to a higher pressure to test the performance of pipelines or containers under different pressure environments, it is often necessary to manually operate multiple valves or go through complex program settings. This process is time-consuming. In addition, when adjusting the supply pressure, some pressure test devices do not change the pressure accurately and smoothly, and the pressure may be instantly too high or too low. This not only affects the accuracy of the test results, but may even cause damage to the tested object.

[0004] Therefore, in order to address the problem that the above-mentioned existing pressure-pressing device cannot quickly adjust the supply pressure, a pressure-pressing device that can quickly adjust the supply pressure can be designed. The high-pressure plunger pump provides high pressure to the equipment to be pressure tested and the electric ball valve is opened to gradually release the pressure in the pressure relief valve, thereby achieving rapid adjustment of the supply pressure.

By slowly closing the control valve 2 at the outlet of the high-pressure plunger pump, the outlet pressure of the high-pressure pump is continuously increased until the required test pressure is reached. After the pressure test is completed, the electric ball valve is opened and the pressure is gradually released through the pressure relief valve, so as to facilitate rapid pressure changes. By pulling the sliding plate left and right, the electric ball valve and the pressure relief valve are moved accordingly, and the corresponding positions of the four flange interfaces are changed. The connectivity of the device is ensured by the extension of the elastic tube, which is convenient for adjustment according to the length of the equipment to be pressure tested, thereby improving the adaptability of the device.
