Problems solved by technology
There are many pressure gauges installed in high and far places, which are not convenient for viewing and inspecting
Inconvenience to regulation
How to solve this problem? There are a lot of working sites, and it is changed to a large dial, which brings difficulties to the production pressure gauge enterprises, mainly because the largest pressure gauge in China can only achieve a straight diameter of 250MM. And the quality is very unstable, and the price is expensive.
Bring unnecessary economic burden to the user unit

Embodiment Construction
[0016] see Figure 1-Figure 2 As shown, the technical solution adopted in this specific embodiment is: it includes a disc 1, a transparent plastic cover 2, an indicator paper 3, a sleeve 4, and a pressure gauge mounting hole 5; the front surface of the disc 1 is provided with a transparent plastic cover 2. The indicator paper 3 is set in the cavity after the disc 1 is connected with the transparent plastic cover 2, and the transparent plastic cover 2 presses the indicator paper 3 on the surface of the disc 1; the back of the disc 1 is provided with a sleeve 4. A pressure gauge installation port 5 is provided inside the disc 1 corresponding to the sleeve 4 .
[0017] The disc 1 is a stainless steel disc. The disk 1 is made of stainless steel, which can ensure the compressive and bending strength of the disk 1 itself, and is not easily damaged.
[0018] Buckles 21 are provided on the left and right sides of the transparent plastic cover 2 . When it is necessary to put the ind...

The invention discloses an amplification device for a pressure meter dial, and relates to the technical field of pressure meters. The amplification device comprises a disc, a transparent plastic cover, an indicating paper slice, a sleeve and a pressure meter installing hole; the transparent plastic cover is arranged on the front surface of the disc, the indicating paper slice is arranged in a cavity after the disc is connected with the transparent plastic cover, and the transparent plastic cover is pressed the indicating paper slice and pasted on the surface of the disc; the sleeve is arrangedon the back face of the disc, and a pressure meter installing opening is formed inside the disc corresponding to the sleeve. According to the technical scheme, the amplification device for the pressure meter dial has the advantages that the amplification device can amplify pressure indication marks of pressure meters arranged at the high portion or the far portion, watching and cruising are convenient, convenience is brought to supervising work, time and labor are saved, a large-dial-plate pressure meter is not required to be modified in specific working site and can be stably used, and the using cost is low.
Description
technical field [0001] The invention relates to the technical field of pressure gauges, in particular to a pressure gauge dial amplification device. Background technique [0002] Pressure gauge (English name: 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 and it is used in 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. Especially in the process of industrial process control and technical measurement, due to the high mechanical strength and convenient production of the elastic sensitive components of mechanical pressure gauges, mechanical pressure gauges are more and more widely used. The pressure gauge transmits the pressure deformation to the pointer through the elastic deformatio...
