The invention provides a pressure gauge capable of realizing impurity removing and current stabilization. The pressure gauge is composed of a shell, a spring tube, a pointer, a drive mechanism, a mounting neck, a guidance tube and an impurity stopping block. The spring tube is installed at the shell; the pointer is installed at the shell in a rotatable manner; and the spring tube is connected with the pointer by the drive mechanism. The mounting neck consists of a mounting bracket, a limiting block, a reset element, an impurity draining filter net and a shunt barrel; a drainage through hole is formed in the mounting rack and includes a limiting segment, a transition segment, an impurity collection segment, and an impurity draining segment; the current-limiting block is arranged at the middle part of the limiting segment; the reset element is connected with the limiting block and the mounting rack; the impurity draining filter net is installed in the transition segment; the shunt barrel is installed in the transition segment and is located at one side, far away from the limiting segment, of the impurity draining filter net; and a plurality of shunt holes are formed in the shunt barrel. One end of the guidance tube passes through the side wall of the mounting bracket and extends to the shunt barrel; and the impurity stopping block is installed at the impurity draining segment detachably. The pressure gauge can be used conveniently; and the instantaneous over-pressure impact influence of the medium is low.
Description
technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a pressure gauge capable of removing impurities and stabilizing flow. 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 e...
