Description

Technical Field

[0001] The utility model relates to the technical field of pressure measuring instruments, in particular to a pressure gauge for construction engineering pipeline construction. Background Art

[0002] The pressure gauges of existing technical products are mainly used on equipment with pressure and vibration. Their technical deficiencies mainly lie in the poor resistance to pulse pressure. If the pulse pressure of the measured medium is too large, it will cause damage to the head of the pressure instrument. Therefore, effectively reducing the pulse pressure of the measured medium is a technical problem that needs to be urgently solved when using pressure instruments.

[0003] According to the Chinese patent with patent number CN217819168U, a pressure gauge for construction engineering pipeline construction is disclosed, which is characterized in that it includes a shock-absorbing rubber, the shock-absorbing rubber is in a columnar structure, and instrument pipes are fixedly installed at both ends of the shock-absorbing rubber, and the two instrument pipes are respectively connected to the equipment and the meter head; a pipeline for the flow of the measured medium is opened in the shock-absorbing rubber, the pipeline is connected to the internal cavity of the instrument pipe, and a flow limiting device for limiting the flow of the measured medium is fixedly installed in the cavity.

[0004] By adopting the above scheme, the use of shock-absorbing rubber can effectively reduce the damage to the pressure instrument caused by equipment vibration; by setting a current limiting device in the instrument connection pipe, the flow velocity and flow rate of the measured medium are limited to slow down the pulse pressure of the measured medium, avoid damage to the pressure gauge head, and increase the service life of the gauge head. However, the current limiting main channel of the above device is vertically connected to the pressure gauge, and the buffer channel can only alleviate the impact force of part of the main channel pulse. When the pulse impact force is too large, the pressure gauge will still be impacted to varying degrees. For this reason, we propose a pressure gauge for construction engineering pipeline construction to solve the above problems. Utility Model Content
