Abstract

The invention discloses a pressure measuring tool, comprising a vertical pipe. The top of the vertical pipe is fixedly mounted with a circular plate, and a square hole is opened at the top of the circular plate.A piston plate is arranged in the vertical pipe, and a sealing gasket is arranged on the fixing plate of the piston plate.The outer side of the gasket is slidably and sealingly connected tothe side wall of the vertical pipe. The top of the piston plate is fixedly mounted with a vertical rod, and the top end of the vertical rod extends through the square hole to the top of the circularplate and is fixedly mounted with a pressing plate.A card slot is arranged on both sides of the vertical rod, and a first circular hole is arranged in the inner wall of both sides of the square hole.The sliding sleeve of the first circular hole is provided with a post, and one end of the post away from the vertical rod extends to the outside of the circular plate, and a sliding groove is arrangedon the top inner wall of the first circular hole.The invention has a simple structure, and the worker can easily judge the gas seal of the welded exhaust pipe by viewing the reading of the barometer,and is convenient for the worker to perform the airtightness test on the welded exhaust pipe.

Description

technical field [0001] The invention relates to the technical field of pressure measurement, in particular to a pressure measurement tool. Background technique [0002] The exhaust pipe is installed between the engine exhaust manifold and the muffler, so that the entire exhaust system is flexibly connected, so as to reduce vibration and noise, facilitate installation and prolong the life of the exhaust muffler system. The airtightness and reliability of the exhaust pipe. The exhaust pipe after welding needs to be tested for airtightness to prevent accidents during use due to poor sealing of the weld. At present, there is a lack of a convenient A pressure measurement tool for airtightness testing of welded exhaust pipes, so we propose a pressure measurement tool. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a pressure measuring tool. [0004] In order to achieve the above object, the pre...
