[0002] A pressure gauge is an instrument widely used to measure the pressure of gas or liquid. It provides a readable output by converting the pressure of the measured medium into mechanical displacement or electrical signal. This instrument is suitable for many fields, including industry, petrochemical industry, medical treatment, etc., for monitoring and controlling pressure changes in the system.
[0003] In industrial sites such as boiler rooms, power plants or chemical plants, pressure gauges play a vital role in these environments. The use of pressure gauges is mainly reflected in the real-time monitoring and control of the internal pressure of the system to ensure that the equipment operates in a safe, efficient and economical state. By monitoring the pressure generated by water or gas, overpressure accidents can be effectively prevented to ensure the safety of equipment and personnel.
[0004] However, in the actual use of the above equipment, industrial sites such as boiler rooms often produce high-temperature water vapor as a by-product of their production or energy production process. High-temperature steam may cause the temperature of the pressure gauge to rise, causing the pressure gauge pointer or scale to expand or deform, affecting the accuracy and performance of the pressure gauge. In view of this, we propose an integrated high-precision environmentally friendly pressure gauge. Summary of the invention

[0024] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an integrated high-precision environmentally friendly pressure gauge, including a shell 1, the shell 1 includes an outer shell 101, the inner wall of the outer shell 101 is provided with a heat insulation component, the heat insulation component includes a reinforcing rib 102, an inner shell 103, a pipeline 2, an outer tube 201, a connector 202, an inner tube 203, an instrument panel 3, a glass cover 4, a liquid inlet pipe 5, a cooling pipe 6, a protrusion 7 and a liquid discharge pipe 8.
[0025] In one embodiment of the utility model, the inner wall of the outer shell 101 is fixedly connected with a reinforcing rib 102, and the end of the reinforcing rib 102 away from the outer shell 101 is fixedly connected with the inner shell 103, the inner wall of the inner shell 103 is fixedly connected with the instrument panel 3, the shell 1 is sleeved with the pipeline 2, the pipeline 2 includes an outer tube 201, the shell 1 is sleeved with the outer wall of the outer tube 201, the end of the outer tube 201 away from the shell 1 is fixedly connected with the connecting piece 202, and the end of the connecting piece 202 away from the outer tube 201 is fixedly connected with the inner tube 203, and the inner wall of the inner shell 103 is clamped with a glass cover 4, and the number of the glass cover 4 is set in two groups, and the two groups of glass covers 4 are connected to the inner shell 103. The inner wall of the outer tube 201 is clamped, and the heat conduction effect from the outside of the pressure gauge to the inside of the pressure gauge is weakened by the two groups of glass covers 4. The side wall of the outer tube 201 is sleeved with the liquid inlet pipe 5. The end face of the liquid inlet pipe 5 is fixedly connected to one end of the cooling pipe 6. The other end of the cooling pipe 6 is fixedly connected to the end face of the discharge pipe 8. The discharge pipe 8 is sleeved with the side wall of the outer tube 201. The liquid inlet pipe 5 and the discharge pipe 8 are respectively arranged on both sides of the outer tube 201. The inner wall of the cooling pipe 6 is fixedly connected with a protrusion 7. The number of the protrusions 7 is arranged in several groups. The groups of protrusions 7 are evenly distributed on the inner wall of the cooling pipe 6. The contact area between the cooling pipe 6 and the inside of the shell 1 is expanded by the provided protrusions 7.
[0026] The inner shell 103 and the outer shell 101, the inner tube 203 and the outer tube 201, and the two groups of glass covers 4 are respectively arranged to isolate the inside and the outside of the pressure gauge. Since air is a poor conductor of heat, the conduction of heat to the inside of the pressure gauge can be reduced to maintain the temperature inside the pressure gauge. The liquid inlet pipe 5 and the liquid discharge pipe 8 are connected to the external pipeline. Cold water enters from the liquid inlet pipe 5 and takes away the heat inside the pressure gauge when passing through the cooling pipe 6. At the same time, since the inner wall of the cooling pipe 6 is fixedly connected with the protrusion 7, the contact area between the cooling pipe 6 and the inside of the shell 1 can be expanded, the heat exchange area can be expanded, and the heat exchange efficiency can be improved, so that the pressure gauge always maintains a relatively low stability, keeps the various components in the pressure gauge in a good working environment, improves the accuracy and performance of the pressure gauge, slows down the aging speed of parts in a high temperature environment, and extends the service life of the pressure gauge.
[0027] In addition, in order to further improve the sealing performance of the shell 1, a sealing ring 9 is sleeved on the side wall of the glass cover 4. The sealing ring 9 is made of a flexible material and is snap-fitted to the inner wall of the inner shell 103. The sealing ring 9 improves the sealing degree between the glass cover 4 and the inner shell 103, prevents high-temperature steam from corroding or damaging the materials used in the pressure gauge, and improves the accuracy and performance of the pressure gauge.
[0028] In the utility model, when in use, the inner and outer sides of the pressure gauge are isolated by the respectively arranged inner shell 103 and outer shell 101, inner tube 203 and outer tube 201, and two groups of glass covers 4. Since air is a poor conductor of heat, the conduction of heat to the inside of the pressure gauge can be reduced to maintain the temperature inside the pressure gauge. The liquid inlet pipe 5 and the liquid discharge pipe 8 are connected to the external pipeline. Cold water enters from the liquid inlet pipe 5 and takes away the heat inside the pressure gauge when passing through the cooling pipe 6. At the same time, since the inner wall of the cooling pipe 6 is fixedly connected with the protrusion 7, the contact area between the cooling pipe 6 and the inside of the shell 1 can be expanded to improve the heat exchange efficiency, so that the pressure gauge always maintains a relatively low stability, and keeps the various components in the pressure gauge in a better working environment. Further, the sealing ring 9 improves the sealing degree between the glass cover 4 and the inner shell 103, prevents the high-temperature steam from corroding or damaging the materials used in the pressure gauge, and improves the accuracy and performance of the pressure gauge.
[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
