Description

Pressure gauge improvement

This creation is about a pressure gauge, especially a pressure gauge that can directly adjust the pointer without disassembly.

The creator obtained the "pressure gauge (1)" patent of the Republic of China Patent Bulletin No. 514253, which is a pressure gauge with an early warning effect, which can effectively prevent the occurrence of disasters.

In practice, when you want to increase the pressure range that can be measured by the pressure gauge, you can do so by adding a washer to squeeze the spring, but the pressure pounds may be too large after the gasket is added, which may cause the pointer to shift. To adjust the condition of the pointer offset, it is very inconvenient to disassemble the entire set of pressure gauges before they can be adjusted.

In addition, the spring must have a physical phenomenon of elastic fatigue in the long-term use, so that the detection data is inaccurate, which leads to inaccurate warning. If the gas and fluid pressures are too large and the explosion occurs, the life and property of the personnel will be greatly affected. Threat.

The trick is that the creators have devoted themselves to this issue and created a pressure gauge improvement that directly adjusts the accuracy of the pointer.

The design concept and technology of the present invention mainly comprises a counting indicator scale on the front side of the fixed seat, a high-voltage driving group is arranged on the left side of the fixing seat, and a low-voltage driving group is arranged on the right side of the fixing seat for high and low pressure gas and liquid. Entering, and a magnet is connected between the high-voltage driving group and the low-voltage driving group, so that a high-pressure gas liquid enters at one end and pushes against the low-pressure gas liquid to gradually move toward the low-voltage driving group, and the high-voltage driving group and the low-voltage driving group The magnet between the groups interacts with a magnet disposed at the counting indicator to move a pointer on the counting indicator. If the pointer moves to the warning point, a sensor is disposed above the fixed seat. The warning light or the closing switch will be displayed to prevent the danger from occurring, and when the pointer is out of alignment, the creation is provided with an adjusting member in the low-voltage driving group, which can be directly adjusted by the tool from the outside.
