Pressure gauge

Abstract

The invention discloses a pressure gauge. The pressure gauge is mainly composed of a gauge casing, a fluid input unit, a bourdon pipe, an indicator, a movement, an indication panel and a transparent face cover. The fluid input unit is composed of a mounting seat arranged on the inner bottom surface of the gauge casing and a connector capable of being fixedly mounted on the mounting seat; the inside of the mounting seat and the connector is provided with a fluid transportation pipe which can transport fluid into the bourdon pipe; and the bourdon pipe is fixedly arranged on the connector. According to the above structure of the pressure gauge, the fluid input unit is formed by assembling the mounting seat and the connector, so that the mounting seat and the connector can be made of plastics and copper respectively to save copper materials partially, further not only copper consumption is reduced, but also the production cost of the pressure gauge can be reduced.

Description

technical field [0001] The invention relates to a pressure gauge and belongs to the technical field of measurement and control instruments. Background technique [0002] At present, pressure gauges are mainly used to measure the pressure of fluids such as gases or liquids. A pressure gauge is generally composed of a watch case, a fluid input part, a Barton tube, a pointer, an indicating panel, a movement and a transparent mask. On the fluid input part, the other end of the Barton tube is connected to a movement, and the movement is connected to a pointer. When the above-mentioned pressure gauge is used to measure the pressure of the fluid, the Barton tube is affected by the fluid pressure, and the end of the Barton tube connected to the movement is deformed, thereby driving the movement of the movement, and the movement drives the pointer to rotate, so that the indicator panel will The pressure of the fluid is expressed. The fluid input part of the existing pressure gauge ...

AI Technical Summary

Problems solved by technology

When the above-mentioned pressure gauge is used to measure the pressure of the fluid, the Barton tube is affected by the fluid pressure, and the end of the Barton tube connected to the movement is deformed, thereby driving the movement of the movement, and the movement drives the pointer to rotate, so that the indicator panel will The pressure of the fluid is expressed. The fluid input part of the existing pressure gauge is generally made of copper metal, and then installed on the watch case. Because the price of copper metal is relatively expensive, the production cost of the pressure gauge is increased. It is not conducive to improving the social competitiveness of enterprises; in addition, it will consume more copper resources, making the global copper resources even more scarce
