Description

Technical Field

[0001] This utility model belongs to the field of corrosion-resistant and shock-resistant stainless steel pressure gauges, and specifically relates to a corrosion-resistant and shock-resistant stainless steel pressure gauge. Background Technology

[0002] Stainless steel pressure gauges are widely used in industrial production and energy transmission. From pipeline pressure monitoring in petrochemical industries to the operation and control of thermal systems, their accurate pressure measurement data is indispensable. As production environments become increasingly complex, pressure gauges need to withstand corrosive media corrosion over long periods, while also resisting mechanical vibrations and equipment operating vibrations. Traditional pressure gauges have limitations in their protective performance, making it difficult to simultaneously meet the requirements for corrosion resistance and vibration resistance. Therefore, there is an urgent need for pressure gauges with new structural designs to ensure the accuracy of measurement data and the long-term stable operation of equipment.

[0003] Existing technologies have specifically developed some corrosion-resistant and shock-resistant stainless steel pressure gauges. For example, Chinese patent publication number "CN216815840U" discloses "A Corrosion-Resistant and Shock-Resistant Stainless Steel Pressure Gauge." Through a first protective mechanism, users can easily install the protective shell onto the stainless steel pressure gauge body using a snap-fit ​​method. The protective shell, along with the buffer plate and first compression spring installed inside, work together to protect the stainless steel pressure gauge body from severe corrosion and to prevent damage from impacts and vibrations. The second protective mechanism prevents excessive vertical vibrations caused by water pressure entering the stainless steel pressure gauge body and provides vibration buffering.

[0004] Although the first protective mechanism allows users to easily install the protective housing onto the stainless steel pressure gauge body via a snap-fit ​​method, and the protective housing, along with the buffer plate and the first compression spring installed inside, work together to protect the stainless steel pressure gauge body from severe corrosion and to prevent damage from impacts, this structure only protects the surface of the pressure gauge. Therefore, if the surface of the pressure gauge is impacted, it can still be damaged. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a corrosion-resistant and shock-resistant stainless steel pressure gauge to solve the problems of corrosion-resistant and shock-resistant stainless steel pressure gauges.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A corrosion-resistant and shock-resistant stainless steel pressure gauge includes a stainless steel pressure gauge body. The outer ring of the stainless steel pressure gauge body is provided with a first semi-circular cover and a second semi-circular cover. The upper ends of the first and second semi-circular covers are hinged together. The first and second semi-circular covers are engaged with each other away from the hinge. Semi-circular blocks are movably installed inside the first and second semi-circular covers. The two semi-circular blocks are attached to the outer ring of the stainless steel pressure gauge body away from the first and second semi-circular covers. A connecting seat is integrally formed at the bottom of the first and second semi-circular covers. A first buffer spring is threadedly connected to the end of the connecting seat away from the first and second semi-circular covers. An external threaded sleeve is fixedly installed at the end of the first buffer spring away from the connecting seat. A protective frame is movably installed on one side of the stainless steel pressure gauge body. A transparent glass plate is provided inside the protective frame.

[0008] As a preferred technical solution, both the first and second semicircular covers have mounting grooves inside, and multiple first supports are fixedly installed inside each mounting groove. A shock-absorbing spring is fixedly installed on the end of each of the multiple first supports away from the mounting groove.

[0009] As a preferred technical solution, the two semicircular blocks have multiple second supports integrally formed on their outer rings, and the ends of the multiple shock-absorbing springs away from the first support are fixedly installed on the ends of the second supports away from the semicircular blocks.

[0010] As a preferred technical solution, the bottom of the first semicircular cover is fixedly installed with plug-in blocks on both sides of the second semicircular cover. The bottom of the second semicircular cover is provided with plug-in grooves on both sides of the end of the second semicircular cover that is close to the first semicircular cover. The plug-in blocks are inserted into the plug-in grooves.

[0011] As a preferred technical solution, a slot is provided on one side of the insertion groove, and slots are provided inside both insertion blocks. A locking spring is fixedly installed inside each slot, and a locking block is fixedly installed at the end of the locking spring away from the slot. The locking block is locked inside the slot.

[0012] As a preferred technical solution, multiple buffer ports are provided inside one side of the stainless steel pressure gauge body. A second buffer spring is fixedly installed inside the buffer port. A buffer column is fixedly installed at the end of the second buffer spring away from the buffer port. The ends of the multiple buffer columns away from the second buffer spring are fixedly installed on one side of the protective frame.

[0013] As a preferred technical solution, a connecting ring is fixedly installed on the upper end of the first buffer spring. The connecting ring is threaded inside the connecting seat, and the first buffer spring is connected to the bottom of the first semi-circular cover and the second semi-circular cover through the connecting ring.

[0014] In summary, the present invention has the following main advantages:

[0015] The transparent glass plate inside the protective frame ensures that operators can clearly observe the pressure gauge readings while preventing corrosive gases and liquids from directly contacting the pressure gauge dial. The first and second semi-circular covers enclose most of the stainless steel pressure gauge body, reducing its contact area with the external corrosive environment and enhancing its overall corrosion resistance. In addition, the buffer structure consisting of a buffer port, a second buffer spring, and a buffer column on one side of the stainless steel pressure gauge body buffers the impact force from the side. When the side is hit by a collision or vibration, the buffer column compresses the second buffer spring within the buffer port, converting the impact force into the elastic potential energy of the spring, reducing the impact on the internal structure of the pressure gauge body and further improving its shock resistance.

The outer ring of the stainless steel pressure gauge body 3 is provided with a first semi-circular cover 2 and a second semi-circular cover 4. The upper ends of the first semi-circular cover 2 and the second semi-circular cover 4 are hinged. The first semi-circular cover 2 and the second semi-circular cover 4 are engaged and installed away from the hinge. Semi-circular blocks 15 are movably installed inside the first semi-circular cover 2 and the second semi-circular cover 4. The two semi-circular blocks 15 are attached to the outer ring of the stainless steel pressure gauge body 3 away from the first semi-circular cover 2 and the second semi-circular cover 4. The bottom of the first semi-circular cover 2 and the second semi-circular cover 4 are integrally formed with a connecting seat 11. The end of the connecting seat 11 away from the first semi-circular cover 2 and the second semi-circular cover 4 is threadedly connected to a first buffer spring 5. The end of the first buffer spring 5 away from the connecting seat 11 is fixedly installed with an external threaded sleeve 6. A protective frame 1 is movably installed on one side of the stainless steel pressure gauge body 3. The protective frame 1 is provided with a transparent glass plate inside.

[0025] refer to Figures 5 to 6 The first semicircular cover 2 and the second semicircular cover 4 are both provided with mounting grooves 22. Multiple first supports 13 are fixedly installed inside the mounting grooves 22. Shock-absorbing springs 16 are fixedly installed at the ends of the multiple first supports 13 away from the mounting grooves 22. Two semicircular blocks 15 are formed with multiple second supports 14 on their outer rings. The ends of the multiple shock-absorbing springs 16 away from the first supports 13 are fixedly installed at the ends of the second supports 14 away from the semicircular blocks 15. The first semicircular cover 2 and the second semicircular cover 4 enclose most of the stainless steel pressure gauge body 3, reducing its contact area with the external corrosive environment and enhancing the overall corrosion resistance.

[0026] refer to Figures 3 to 4 The bottom of the first semi-circular cover 2 is fixedly installed with plug-in blocks 17 on both sides of the second semi-circular cover 4. The bottom of the second semi-circular cover 4 is provided with plug-in grooves 18 on both sides of the end of the first semi-circular cover 2. The plug-in blocks 17 are inserted into the plug-in grooves 18. A slot 21 is provided on one side of the plug-in groove 18. Both plug-in blocks 17 have slots 20 inside. A locking spring 19 is fixedly installed inside the slots 20. A locking block 10 is fixedly installed on the end of the locking spring 19 away from the slot 20. The locking block 10 is locked onto the locking plate. Inside the groove 21, the first semicircular cover 2 and the second semicircular cover 4 are opened through the hinge structure at the upper end, and then closed after being fitted onto the outer ring of the stainless steel pressure gauge body 3. This allows the insertion block 17 at the bottom of the first semicircular cover 2 to be inserted into the insertion groove 18 of the second semicircular cover 4. The locking block 10 is springed into the locking groove 21 under the action of the locking spring 19, thus achieving a stable engagement of the first semicircular cover 2 and the second semicircular cover 4. At this time, the semicircular block 15 is tightly fitted inside the first semicircular cover 2 and the second semicircular cover 4 with the outer ring of the stainless steel pressure gauge body 3, forming initial protection.

[0027] refer to Figure 2Multiple buffer ports 7 are provided on one side of the stainless steel pressure gauge body 3. A second buffer spring 8 is fixedly installed inside the buffer port 7. A buffer column 9 is fixedly installed at the end of the second buffer spring 8 away from the buffer port 7. The ends of the multiple buffer columns 9 away from the second buffer spring 8 are fixedly installed on one side of the protective frame 1. The buffer structure composed of the buffer port 7, the second buffer spring 8 and the buffer column 9 on one side of the stainless steel pressure gauge body 3 buffers the impact force from the side. When the side is hit by a collision or vibration, the buffer column 9 compresses the second buffer spring 8 in the buffer port 7, converting the impact force into the elastic potential energy of the spring, reducing the impact on the internal structure of the pressure gauge body, and further improving the shock resistance during daily maintenance.

[0028] refer to Figures 1 to 5 A connecting ring 12 is fixedly installed on the upper end of the first buffer spring 5. The connecting ring 12 is threaded inside the connecting seat 11. The first buffer spring 5 is connected to the bottom of the first semi-circular cover 2 and the second semi-circular cover 4 through the connecting ring 12. The first buffer spring 5 can effectively relieve the vertical vibration of the pressure gauge.

[0029] Operating principle and advantages: Before using this corrosion-resistant and shock-resistant stainless steel pressure gauge, the stainless steel pressure gauge body 3 is first installed and fixed using the first semi-circular cover 2 and the second semi-circular cover 4. The first semi-circular cover 2 and the second semi-circular cover 4 are opened via the upper hinge structure, fitted onto the outer ring of the stainless steel pressure gauge body 3, and then closed. This allows the insertion block 17 at the bottom of the first semi-circular cover 2 to be inserted into the insertion groove 18 of the second semi-circular cover 4. The locking block 10, under the action of the locking spring 19, springs into the locking groove 21, achieving a stable engagement of the first semi-circular cover 2 and the second semi-circular cover 4. At this time, the semi-circular block 15 is tightly fitted inside the first semi-circular cover 2 and the second semi-circular cover 4 against the outer ring of the stainless steel pressure gauge body 3, forming initial protection. Then, the bottom connection of the first semi-circular cover 2 and the second semi-circular cover 4... The first buffer spring 5 is installed on the seat 11, and the external threaded sleeve 6 is screwed into the internal thread structure of the installation position. The connecting ring 12 at the upper end of the first buffer spring 5 is threadedly connected to the connecting seat 11. By adjusting the screw depth of the connecting ring 12 in the connecting seat 11, the preload of the first buffer spring 5 can be adjusted, so that the pressure gauge can adapt to different working environments and vibration conditions after installation. During the operation of the pressure gauge, the vibration and corrosion risks it faces are dealt with by multiple structures working together. When external vibration occurs, the first buffer spring 5 can absorb the vibration energy from the bottom and reduce the impact of vibration on the pressure gauge body through its own elastic deformation. At the same time, the shock-absorbing spring 16 inside the first semi-circular cover 2 and the second semi-circular cover 4 plays a role, with one end connected to the first support. 13. The other end is connected to the second support 14 on the semicircular block 15. When the vibration is transmitted to the first semicircular cover 2 and the second semicircular cover 4, the shock-absorbing spring 16 is compressed or stretched to further disperse and buffer the vibration, protecting the stainless steel pressure gauge body 3 from vibration interference and ensuring the accuracy of the measurement data. In terms of corrosion prevention, the first semicircular cover 2, the second semicircular cover 4, and the protective frame 1 form a physical isolation barrier. The transparent glass plate inside the protective frame 1 can not only ensure that the operator can clearly observe the pressure gauge reading, but also prevent external corrosive gases and liquids from directly contacting the pressure gauge dial. The first semicircular cover 2 and the second semicircular cover 4 enclose most of the stainless steel pressure gauge body 3, reducing its contact area with the external corrosive environment and enhancing the overall corrosion resistance. Furthermore, the buffer structure consisting of the buffer port 7, the second buffer spring 8, and the buffer column 9 on one side of the stainless steel pressure gauge body 3 buffers the impact force from the side. When the side is subjected to a collision or vibration, the buffer column 9 compresses the second buffer spring 8 within the buffer port 7, converting the impact force into the elastic potential energy of the spring, reducing the impact on the internal structure of the pressure gauge body, and further improving the shock resistance. During routine maintenance, if it is necessary to inspect or replace pressure gauge components, the first semi-circular cover 2 and the second semi-circular cover 4 can be separated first. Press the locking block 10 to make it retract into the slot 20 against the elastic force of the locking spring 19, releasing the locking state of the first semi-circular cover 2 and the second semi-circular cover 4. Then, open the hinge structure to easily remove the first semi-circular cover 2 and the second semi-circular cover 4.Inspect and maintain components such as the stainless steel pressure gauge body 3, semi-circular block 15, and shock-absorbing spring 16.
