Description
Technical Field
The utility model relates to a pressure measurement equipment field especially relates to a quick gas leakage detection device of pressure vessel.
Background
The pressure container is a closed device which contains gas or liquid and bears a certain pressure. For a pressure container for containing gas, gas leakage is a problem to be solved in the design and production processes of the pressure container, and firstly, whether the pressure container leaks gas or not is detected. The method for detecting the air leakage of the pressure container disclosed at present is a method for detecting whether the pressure in the pressure container changes within a period of time, and the method has the biggest defect that the detection process is long in duration and needs a lot of time, and the other method is a method for detecting whether bubbles are generated or not by immersing the pressure container into water after injecting gas. Both methods are not suitable for the flow line production of pressure container batches, and for this reason, we propose a pressure container rapid air leakage detection device to solve the above problems.

Preferably, an air inlet pipe is fixed at the right end of the round pipe, and an air valve is arranged on the air inlet pipe.
Preferably, the pipe left side is provided with the pressure gauge, the pressure gauge right-hand member runs through pipe annular side left end and extends to in the pipe.
Preferably, a sealing ring is fixedly bonded to the lower end of the annular side surface inside the connecting pipe.
Preferably, the outer annular side processing of pipe lower extreme has the screw thread, the annular side processing has the thread groove in the connecting pipe upper end, the pipe passes through the screw thread with the connecting pipe and can dismantle with the thread groove and be connected.
Preferably, the right end of the air inlet pipe is connected with an external air compressor.
The utility model has the advantages that: the connecting pipe is connected with the connecting pipe of the external pressure container through the connecting pipe and the sealing ring, then the air valve is opened, the pressure container is pressurized through the air inlet pipe, the round pipe and the connecting pipe, whether the external pressure leaks air or not is judged through the movement of the sealing plug, so that the judging process is simplified, the detection efficiency is improved, and the device is suitable for assembly line detection.
