The invention provides an impurity-removal flow-control pressure meter, which comprises a housing, an installation neck, a spring pipe, a pointer and a transmission mechanism. The installation neck comprises an installation frame, a bottom board, an impurity-removal pipe, an impurity collection frame, a filter cartridge, a top plate, a flow guide pipe and a flow control frame. The installation frame is provided with a transition through hole; the impurity-removal pipe is equipped with at least one adjusting value; the impurity collection frame is provided with an impurity collection through hole; the filter cartridge is provided with a plurality of filtering holes; the flow control frame is provided with a flow control through hole; the flow control through hole comprises a first flow control section and a second flow control section; the flow control frame is provided with a positioning rod in the flow control through hole; the positioning rod is removably equipped with a separator plate; the separator plate is connected with the positioning rod through a reset piece; the spring pipe is arranged on the housing; the second end of the transition through hole is communicated with the spring pipe; the pointer is rotatably arranged on the housing; and the spring pipe is connected with the pointer through the transmission mechanism. The impurity-removal flow-control pressure meter is convenient to use and has high measurement accuracy.
Description
technical field [0001] The invention relates to the technical field of instruments and meters, in particular to an impurity removal and flow control type pressure gauge. 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 technical problems existing in t...
