Description

Technical Field

[0001] The utility model belongs to the technical field of pressure gauges, and in particular relates to a stainless steel earthquake-resistant pressure gauge. Background Art

[0002] A pressure gauge is an instrument that uses an elastic element as a sensitive element to measure and indicate pressures higher than the ambient pressure. A stainless steel pressure gauge is a pressure gauge made of stainless steel. Stainless steel pressure gauges have strong resistance to corrosion by the measured medium and environmental corrosion, which makes them widely used in industries such as petroleum, chemical industry, and metallurgy.

[0003] According to the patent of an anti-corrosion and anti-vibration stainless steel pressure gauge with the authorization announcement number CN216815840U, the patent is a known prior art, and although the patent has the advantages of being able to realize corrosion protection and buffering and shock absorption for the stainless steel pressure gauge body, the technical solution of the patent still has the following defects in actual use: in the patent, since a viewport is provided at the front end of the protective shell, when the stainless steel pressure gauge is used in an environment with high humidity, water vapor in the external environment will diffuse from the viewport into the interior of the protective shell and contact with the first compression spring. Over time, the first compression spring is prone to rust or damage due to moisture, which will reduce the elastic performance of the first compression spring, thereby causing the anti-vibration effect of the stainless steel pressure gauge to deteriorate. For this reason, we propose a stainless steel anti-vibration pressure gauge. Utility Model Content

[0021] In this embodiment, when the upper protective shell 1 and the lower protective shell 2 are opened, the stainless steel pressure gauge body 3 can be first placed into the lower protective shell 2, so that the bottom end of the stainless steel pressure gauge body 3 is sleeved inside the sealing gasket 6, and the bottom end of the stainless steel pressure gauge body 3 is extended to the bottom of the lower protective shell 2. At this time, the sealing gasket 6 can use its own elastic properties to seal the contact position between the bottom end of the stainless steel pressure gauge body 3 and the lower protective shell 2. After the stainless steel pressure gauge body 3 is placed, the upper protective shell 1 is sleeved on the outside of the top of the stainless steel pressure gauge body 3, so that the bottom of the upper protective shell 1 and the top of the lower protective shell 2 are in contact, and then the upper protective shell 1 and the lower protective shell 2 are fixed by bolts. At the same time, the transparent cover 4 can be used to observe the values ​​on the dial of the stainless steel pressure gauge body 3. When the fixing bolt is rotated to separate it from the lower protective shell 2, the transparent cover 4 and the lower protective shell 2 will become loose, so that it is convenient to open the lower protective shell 2 upward, and the setting of the rubber ring on the back of the transparent cover 4 can also prevent water vapor in the outside air from diffusing into the upper protective shell 1 and the lower protective shell 2.

[0022] See also Figure 1 and Figure 2The inner sides of the upper protective shell 1 and the lower protective shell 2 are fixedly connected with a shock absorbing assembly 5, the shock absorbing assembly 5 includes a rubber sleeve 51 and a buffer spring 52, the buffer spring 52 is fixedly connected to the inside of the rubber sleeve 51, and the outside of the rubber sleeve 51 is in close contact with the outside of the stainless steel pressure gauge body 3;

[0023] In this embodiment, when the surface of the upper protective shell 1 or the lower protective shell 2 is hit, the generated force will be transmitted inward to the rubber sleeve 51. At this time, the rubber sleeve 51 will perform preliminary buffering and shock absorption due to its own elastic properties. Secondly, the buffer spring 52 will buffer and shock absorb the transmitted force again. In this way, the force transmitted to the surface of the stainless steel pressure gauge body 3 will be greatly weakened, thereby improving the seismic resistance of the stainless steel pressure gauge body 3.

[0024] See also Figure 2 and Figure 3 A fixing assembly 7 is provided at the bottom of the lower protective shell 2. The fixing assembly 7 includes a mounting plate 71.

[0026] The working principle and use process of the utility model are as follows: first, open the upper protective shell 1 and the lower protective shell 2, and put the stainless steel pressure gauge body 3 into the lower protective shell 2, so that the bottom end of the stainless steel pressure gauge body 3 is sleeved inside the sealing gasket 6, and the bottom end of the stainless steel pressure gauge body 3 is extended to the bottom of the lower protective shell 2. At this time, the sealing gasket 6 can use its own elastic properties to seal the contact position between the bottom end of the stainless steel pressure gauge body 3 and the lower protective shell 2;

[0027] Then, the adjusting bolt 72 is rotated to rotate and move, and the adjusting bolt 72 drives the connecting block 73 to move horizontally, and the connecting block 73 drives the fixing block 74 to move horizontally, so that the inner side of the fixing block 74 is in close contact with the outer side of the bottom end of the stainless steel pressure gauge body 3, and the bottom end of the stainless steel pressure gauge body 3 can be adjusted and fixed, thereby improving the stability of the stainless steel pressure gauge body 3 inside the upper protective shell 1 and the lower protective shell 2;
