Description

Technical Field

[0001] This invention belongs to the field of pressure measurement of sealed containers, and particularly relates to a device for measuring the pressure of a container with an insulating coating on the inside. Background Technology

[0002] Currently, many industrial applications involve corrosive liquids or gases that react with metals. When storing corrosive liquids or gases in metal containers, an insulating coating with anti-corrosion properties is often sprayed inside the container, as in pressurized fire extinguishers. However, due to the presence of the insulating coating, pressure sensors cannot form an electrical circuit, thus preventing the measurement of the pressure inside the container. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention provides an apparatus for measuring the pressure of a container with an insulating coating on its inner side. To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or to define the scope of protection of these embodiments. Its sole purpose is to present some concepts in a simple form as a prelude to the detailed description that follows.

[0004] The present invention adopts the following technical solution: In some optional embodiments, a device for measuring the pressure of a container with an inner insulating coating is provided, comprising: a container with an inner insulating coating, an insulating sealing ring, a container cap, an elastic conductive breakthrough head, a pressure sensor, and a pressure display; the container with the inner insulating coating is connected to the container cap through the insulating sealing ring; the container with the inner insulating coating and the container cap are made of conductive material; the elastic conductive breakthrough head and the pressure sensor are disposed inside the container with the inner insulating coating; the pressure display is disposed outside the container with the inner insulating coating; the elastic conductive breakthrough head can break the insulating coating inside the container and form an electrical connection with the container shell; one end of the pressure sensor is electrically connected to the elastic conductive breakthrough head; the other end of the pressure sensor is electrically connected to the container cap; one end of the pressure display is electrically connected to the elastic conductive breakthrough head; the other end of the pressure display is electrically connected to the container cap.

[0005] Furthermore, the container with an insulating coating on the inside can be made of metal.

[0006] Furthermore, the container with an insulating coating on the inside can be made of aluminum;

[0007] Furthermore, the container with an insulating coating on the inside can be made of steel;

[0008] Furthermore, the elastic conductive breakthrough head can be made of metal.

[0009] Furthermore, the elastic conductive breakthrough head can be made of steel;

[0010] The beneficial effects of this invention are as follows:

[0011] After a container with an insulating coating on its inner side is manufactured, the inner wall has a complete insulating coating, making the interior of the container non-conductive. During installation, a flexible conductive breakthrough probe can penetrate the insulating coating inside the container, establishing an electrical connection between the probe and the container. Since one end of the pressure sensor is electrically connected to the flexible conductive breakthrough probe, and the other end is connected to the container cap, a conductive circuit can be formed, allowing for the measurement of the internal pressure of the sealed container with its insulating coating.

[0014] The following description and accompanying drawings fully illustrate specific embodiments of the invention to enable those skilled in the art to practice them. Other embodiments may include structural, logical, electrical, procedural, and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the order of operation may vary. Some portions and features of some embodiments may be included in or replace portions and features of other embodiments.

[0015] like Figure 1As shown in some illustrative embodiments, an apparatus for measuring the pressure of a container with an insulating coating on its inner side is provided, comprising: a container 1 with an insulating coating on its inner side, an insulating sealing ring 2, a container cap 3, a flexible conductive penetration head 4, a pressure sensor 5, and a pressure display 6; the container 1 with the insulating coating on its inner side is connected to the container cap 3 via the insulating sealing ring 2; the container 1 with the insulating coating on its inner side and the container cap 3 are made of conductive material; the flexible conductive penetration head 4 and the pressure sensor 5 are disposed inside the container 1 with the insulating coating on its inner side; the pressure display 6 is disposed outside the container 1 with the insulating coating on its inner side; the flexible conductive penetration head 4 can break the insulating coating inside the container and form an electrical connection with the container shell; one end of the pressure sensor 5 is electrically connected to the flexible conductive penetration head 4; the other end of the pressure sensor 5 is electrically connected to the container cap 3; one end of the pressure display 6 is electrically connected to the flexible conductive penetration head 4; the other end of the pressure display 6 is electrically connected to the container cap 3.

[0016] This invention discloses a device for measuring the pressure of a container with an inner insulating coating. After the container 1 with the inner insulating coating is manufactured, its inner wall has a complete insulating coating, resulting in a non-conductive state inside the container. During installation, the elastic conductive breakthrough head 4 can penetrate the insulating coating inside the container, forming an electrical connection between the elastic conductive breakthrough head 4 and the container. Since one end of the pressure sensor 5 is electrically connected to the elastic conductive breakthrough head 4, and the other end of the pressure sensor 5 is connected to the container cap 3, and both the outer layer of the container 1 with the inner insulating coating and the container cap 3 are made of conductive material, installing the elastic conductive breakthrough head 4 is equivalent to forming an electrical connection between the outer layer of the container 1 with the inner insulating coating and the container cap 3, respectively, to both ends of the pressure sensor 5. Because the insulating sealing ring 2 is positioned between the container 1 with the inner insulating coating and the container cap 3, no electrical connection is formed between the container 1 with the inner insulating coating and the container cap 3, thus preventing a short circuit. After electrically connecting the two ends of the pressure display 6 on the outside of the container to the outer layer of the container 1 with the insulating coating on the inside and the container cap 3, a complete pressure measurement circuit can be formed, which can measure the pressure inside the container.

[0019] The container 1 with an insulating coating on its inner side in the device for measuring the pressure of a container with an insulating coating on its inner side in this invention can be made of steel, which has good electrical conductivity and stability.

[0020] The container 1 with an insulating coating on its inner side in the device for measuring the pressure of a container with an insulating coating on its inner side in this invention can be made of metal. Metal has good conductivity and stability, and when made into a sheet, it also has good elasticity.

[0021] The elastic conductive breakthrough head 4 in the device for measuring the pressure of a container with an insulating coating on the inside of the present invention can be made of steel. Steel has good conductivity and stability, and when made into a sheet, it also has good elasticity.
