Abstract

The invention provides a pressure gauge capable of effectively reducing medium pressure change influence. The pressure gauge comprises a gauge housing, a gauge pointer, a bourdon tube, a transmission mechanism, an installation mechanism and a flow guide mechanism. The gauge pointer is rotatably arranged on the gauge housing; the bourdon tube is arranged on the gauge housing; and the bourdon tube is connected with the gauge pointer through the transmission mechanism. The installation mechanism comprises an installation frame, a bottom plate, an impurity storage frame, a filter cartridge and a top plate. The filter cartridge is provided with a plurality of filtering holes; the impurity storage frame is provided with an impurity storage tank; and the impurity storage tank is cooperated with an internal through hole of the filter cartridge to form a flow accommodation cavity. The flow guide mechanism comprises a flow guide main pipe, a branch pipe, two flow guide branch pipes and two tail pipes. The pressure gauge is convenient to use, and can keep precision in long-term measurement.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a pressure gauge that can effectively alleviate the influence of medium pressure changes. Background technique [0002] A pressure gauge is an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is widely used, and it pervades almost all industrial processes and scientific research fields. It can be seen everywhere in heat pipe network, oil and gas transmission, water supply and gas supply system, vehicle repair and maintenance factory and shop. During the use of the pressure gauge, the pointer may deviate due to the instantaneous overpressure impact of the medium, which affects the accuracy of the pressure gauge detection, and the pressure gauge may also have the possibility of impurity accumulation that affects the pressure gauge detection. Contents of the invention [0003] Based on the ...
