Description

Technical Field

[0001] This utility model relates to the field of pressure gauge antifreeze, and in particular to a pressure gauge with antifreeze protection. Background Technology

[0002] In many industrial applications, pressure gauges are widely used as important measuring instruments to monitor and control process parameters.

[0003] Existing pressure gauges are directly connected to the end being measured. However, in cold climates, especially in winter, the medium being measured by the pressure gauge often freezes due to low temperatures. This freezing prevents the pressure gauge from functioning properly, resulting in inaccurate display of measurement parameters and affecting the stability and safety of the production process. Therefore, the lack of antifreeze protection makes it impossible for the pressure gauge to be used stably in cold climates. In view of this, this solution proposes a pressure gauge with antifreeze protection to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-4 The pressure gauge shown includes:

[0026] Pressure gauge body 1;

[0027] The antifreeze wrapping mechanism is sleeved on the outer wall of the pressure gauge body 1 and is used to wrap the pressure gauge body 1 to prevent freezing.

[0028] Specifically, the antifreeze wrapping mechanism includes an air supply pipe 2, which is wrapped around the outer wall of the pressure gauge body 1, and the outer wall of the pressure gauge body 1 is provided with a blocking component.

[0029] It should be noted that the gas source pipe 2 can adopt a sheet-like or cylindrical tube structure. In this design, a sheet-like tube structure is adopted. This structure allows the gas source pipe 2 to have a larger contact area when it is wrapped around the surface of the pressure gauge body 1. This allows for greater contact area to heat and protect the pressure gauge body 1 from freezing when the heat source passes through the gas source pipe 2.

[0030] Furthermore, the blocking component includes blocking protrusions 101. Multiple blocking protrusions 101 are arranged around the outer wall of the pressure gauge body 1, and multiple blocking protrusions 101 are horizontally and centrally symmetrically arranged on both sides of the air source pipe 2. The blocking protrusions 101 restrict the air source pipe 2 from being sleeved on the outer wall of the pressure gauge body 1.

[0031] It should be noted that by setting the blocking protrusion 101, the two sides of the air source pipe 2 are bound when it is fitted with the pressure gauge body 1, preventing the air source pipe 2 from sliding off from the front or back of the pressure gauge body 1. When the air source pipe 2 is connected to the surface of the pressure gauge body 1, the connection contact surface of the two can also be fixed by welding, thereby ensuring that the air source pipe 2 and the surface of the pressure gauge body 1 are tightly fitted.

[0032] Connectors are located at both ends of the antifreeze wrapping mechanism. The connectors are used for through connection between the two ends of the antifreeze wrapping mechanism. The two ends of the air source pipe 2 are used for connection of the connectors.

[0033] Specifically, the connectors include:

[0034] The first connector 3 is connected to one end of the gas source pipe 2.

[0035] The second connector 4 is connected to the other end of the gas source pipe 2.

[0036] Furthermore, a first flange 301 is provided at the end of the first connector 3 away from the gas source pipe 2, and a second flange 401 is provided at the end of the second connector 4 away from the gas source pipe 2.

[0037] It should be noted that the two ends of the air source pipe 2 are respectively set as the inlet end and the outlet end. The inlet end is sealed and welded to the first connector 3, and the outlet end is sealed and welded to the second connector 4. Both the first connector 3 and the second connector 4 adopt a round pipe structure and are externally installed using the first flange 301 and the second flange 401 respectively.

[0038] The control component is located at one end of the antifreeze packaging mechanism and is connected to the connector. The control component is used for the conduction control of the antifreeze packaging mechanism. The first connector 3 is connected to the control component through the first flange 301.

[0039] Specifically, the control component includes a shut-off valve 5, one end of which is detachably and fixedly connected to the first flange 301, and the shut-off valve 5 is connected through the first connector 3.

[0040] It should be noted that the flange head at the shut-off valve 5 is detachably connected to the first flange 301 by bolts. Under the control of the shut-off valve 5, hot steam enters the first connector 3 through the shut-off valve 5, and is then guided by the first connector 3 to the gas source pipe 2. The hot steam generates condensate through heat exchange in the gas source pipe 2, and the condensate is then discharged through the second connector 4.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
