Abstract

The invention discloses an anti-strong-erosion diaphragm pressure gauge. The anti-strong-erosion diaphragm pressure gauge comprises a pressure gauge housing. An axial center on a front surface of the pressure gauge housing is rotatably connected to a rotation shaft. A pointer is fixed connected to the surface of the rotation shaft. A dial gauge is arranged in the front surface of the pressure gauge housing. The bottom of the pressure gauge housing is connected to an instrument seat. A flange seat is fixedly connected to the bottom on the surface of the instrument seat. Bearing plates are connected to tops on two sides of the instrument seat. Through cooperation between the bearing plates, a protection box, screws, nuts, strong pressure resistance layer, a graphite layer, a resin coating layer, a bituminous varnish layer and a paint layer, the anti-strong-erosion diaphragm pressure gauge achieves a strong erosion resistance effect, solves a problem that the current diaphragm pressure gauge does not have a strong anti-erosion function, prevents the diaphragm gauges from being eroded, guarantees accuracy of a measurement numerical value, reduces the damage rate of the diaphragm pressure gauge and thus improves practicability of the diaphragm pressure gauge.

Description

technical field [0001] The invention relates to the technical field of pressure gauges, in particular to an anti-corrosion diaphragm pressure gauge. Background technique [0002] A pressure gauge refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is widely used. It is used in almost all industrial processes and scientific research fields. Repair and maintenance factories and shops can be seen everywhere, especially in the process of industrial process control and technical measurement, because the elastic sensitive components of mechanical pressure gauges have high mechanical strength and convenient production, so mechanical pressure gauges are getting more and more popular. Wide range of applications. [0003] Diaphragm pressure gauges need to be installed on the pipes in the processing workshops of chemical plants in order to measure pressure values. At present, the existing diaphragm p...
