Description

Technical Field

[0001] The utility model relates to the field of pipeline detection, in particular to a tooling for detecting the pressure limit of pipelines in a chemical production line. Background Art

[0002] During the chemical production process, pipelines are subjected to various pressures. To ensure production safety, it is necessary to regularly test the pressure limit of the pipelines. At present, the commonly used detection method is to test the pressure bearing capacity of the pipelines through water pressure tests or air pressure tests. During the air pressure test, the staff needs to observe the pipelines with the naked eye on site to see if there are any leaks, etc. This inspection method is not accurate enough. The installation locations of some chemical production line pipelines are relatively special, which is not convenient for staff to observe. It is easy to make misjudgments if the staff only rely on naked eye observation, and there are certain safety hazards, which makes it inconvenient to use. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a chemical production line pipeline pressure limit detection tooling, including a pipeline body and a sealing member, a detection valve and a pressure relief valve are respectively provided on one side of the top of the pipeline body, and a sealing member is provided on the top and bottom of the outer periphery of the pipeline body, an air pressure sensor, an alarm and a control console are respectively provided on the top of the sealing member, and a first sealing gasket and a second sealing gasket are respectively provided on the inner side of the sealing member.

[0005] Furthermore, the inner side of the seal is separated into a plurality of sealing detection chambers by the first sealing gasket, and each of the air pressure sensors corresponds to the sealing detection chamber. The first sealing gasket is used to separate several independent sealing detection chambers, and the corresponding air pressure sensors are used to detect the air pressure in the corresponding sealing detection chambers. If a leak occurs, the air pressure in the sealing detection chamber rises, and the corresponding air pressure sensor can detect it immediately. The console displays the abnormal signal of the corresponding air pressure sensor, which is convenient for the staff to quickly locate the leaking area.

[0006] Furthermore, both ends of the seal are provided with a connector and a connecting bolt, and the upper and lower seals are connected and fixed by the connector and the connecting bolt, and the inside is sealed and protected by a second sealing gasket. After the staff installs the seal on the periphery of the pipeline body, the seal can be connected and fixed by installing and tightening the connector and the connecting bolt. During the inspection process, the seal is used to wrap and seal the periphery of the pipeline body, and the second sealing gasket is used to increase the sealing effect of the seal.

[0007] Furthermore, the air pressure sensor is electrically connected to the control console, and the alarm is electrically connected to the control console. If a leak occurs, the air pressure sensor can detect it immediately, the alarm will sound an alarm, and the control console will display an abnormal signal of the corresponding air pressure sensor.

[0008] Furthermore, the input end of the detection valve is connected to an external air pump through an air pipe. After the external air pump is started, air is gradually inflated and pressurized into the pipeline body through the air pipe, and the pressure is detected by a pressure gauge. When the detection pressure is reached, the pressure is kept stable for a period of time, and during this period, the pipeline body 1 is observed to see if there is any abnormality such as leakage.

[0009] Furthermore, a pressure gauge is provided on one side of the pressure relief valve, and a pressure relief pipe is provided at the output end of the pressure relief valve. The pressure condition in the pipeline body is detected by the pressure gauge, and the gas in the pipeline body is discharged through the pressure relief pipe after the pressure relief valve is opened to perform pressure relief work.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] During the detection process, the utility model wraps and seals the periphery of the pipeline body through the sealing member, separates several independent sealing detection chambers through the first sealing gasket, and cooperates with the corresponding air pressure sensor to detect the air pressure conditions in the corresponding sealing detection chambers. If a leakage occurs, the air pressure in the sealing detection chamber rises, and the corresponding air pressure sensor can detect it at the first time, and the alarm device sends out an alarm reminder, and the console displays the abnormal signal of the corresponding air pressure sensor, which is convenient for the staff to carry out detection and observation work, and is convenient for the staff to quickly locate the leakage area, thereby increasing the practicality of the device.
