Description

pressure gauge

This creation is based on a pressure gauge, especially a pressure gauge that can be adjusted directly without disassembly.

According to this, the creator previously obtained the pressure gauge (2) patent case of the Republic of China Patent Bulletin No. 495026, which is a pressure gauge with early warning function, which can effectively prevent the occurrence of disasters.

In the previous 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. However, after the gasket is added, the pressure pound of the pressure gauge may be too large, causing the pointer to shift. Or the pointer can not reach the required scale point position, it is very inconvenient to disassemble the cover of the whole group of pressure gauges and then adjust the pointer.

Moreover, the spring must have a physical phenomenon of elastic fatigue when it is squeezed for a long time, so that the pressure gauge detects inaccurate data, which leads to inaccurate warning. If the gas and fluid pressures are too large and an explosion occurs, the life and property of the personnel will be caused. Both are greatly threatened.

In view of this, the creators of this case specially studied the problems caused by the above general pressure gauges, and created a pressure gauge that does not need to disassemble any components of the pressure gauge, that is, the position of the scale point of the pointer directly adjusted by the external pressure gauge. .

In order to achieve the above-mentioned creative purpose, the technical means used in the present invention is to provide a "pressure gauge" having a low-voltage driving group on a first fixed body and a high-voltage driving group in a second fixed body, using the high-voltage driving group. The interaction between a magnet disposed inside and a magnet disposed at a counting indicator scale, thereby pushing a pointer on the counting indicator to move to the warning point, and immediately informing the high voltage driving A sensor above the group notifies the warning or closing action, and when the pressure gauge of the pressure gauge may be too large or the elastic fatigue is caused after the spring is used for a long time, when the pointer is out of alignment, the creation is in the low-voltage driving group. An adjusting member is provided, and the adjusting member can be directly inserted into the adjusting member from the outside of the low-voltage driving group and the pointer offset can be adjusted without disassembling any components of the pressure gauge.

The structural design of the above-mentioned creation pressure gauge can mainly achieve the following effects:

First: The creation pressure gauge has the function of regulating the required pressure setting, which can make the pressure gauge have the basic function and the early warning notification function.

Secondly, the creation interacts with a magnet disposed inside the high-voltage driving group and a magnet disposed at a counting indicator. The pointer on the counting indicator is moved to the warning point and immediately notified.

Third: The creation has the effect of adjusting the set pressure. The user can set different sensing pressures according to the different gas and liquid of the machine to improve the sensing efficiency, and can fully inform the effect and ensure high safety.

Fourth: This creation improvement knows that the cover of the whole set of pressure gauges must be disassembled to adjust the lack of pointer offset. By means of an adjustment component provided in the low-voltage drive group, it can be extended from the outside of the low-voltage drive group. It is very convenient to adjust the pointer offset directly.
