Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge measurement technology, specifically a positive pressure sealing connection structure for a liquid level gauge. Background Technology

[0002] A level gauge is an instrument used to measure the liquid level in a container, also known as a level sensor. It can detect changes in liquid level and is widely used in industrial production, mainly for monitoring and controlling the storage of liquid raw materials and finished products to ensure the stability of the production process and the quality of the products. Common types of level gauges include magnetic levitation, pressure, ultrasonic, and radar types. When using level gauges, a positive pressure sealing connection structure is usually required. The positive pressure sealing connection structure is a connection device used to ensure that the level gauge can accurately measure the liquid level and prevent media leakage under positive pressure. The working principle of the positive pressure sealing connection structure is based on the elastic deformation of the sealing gasket caused by the compression between the connecting flanges to achieve sealing. When the container is under positive pressure, the medium exerts outward pressure on the connection part. The connecting flanges, through the pre-tightening force provided by the fastening bolts, press the sealing gasket tightly between the two flanges, causing the sealing gasket to elastically deform and fill the unevenness of the flange surface, thereby preventing media leakage. However, the existing positive pressure sealing connection structure cannot effectively seal the liquid, and it is inconvenient to install the sealing gasket, making it relatively inconvenient to use and unable to provide multi-layer protection.

[0029] 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.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a positive pressure sealing connection structure for a liquid level gauge, including a flange 10, a flange 20, a screw 30, a sealing gasket 40, a gasket 401, a groove 402, a sealing gasket 2 50, a gasket 2 501, and a protrusion 502.

[0031] The positive pressure sealing connection structure of this level gauge facilitates improved sealing of the device connection. The specific implementation method is as follows:

[0032] Flange 10 is connected to flange 20. Screws 30 are installed at equal intervals between flange 10 and flange 20. A sealing gasket 40 is connected to the surface of flange 20, and a gasket 401 is fitted onto the surface of flange 20. A groove 402 is embedded in the surface of gasket 401. A sealing gasket 50 is placed on the surface of flange 10, and gasket 501 is also installed on the surface of flange 10. A protrusion 502 is fixedly connected to the bottom of gasket 501. Flange 10 and flange 20 are connected by screws 30, with flange 20 located at the bottom of flange 10. Sealing gasket 40 is located on the top surface of flange 20 and is annular in shape. The structure includes a sealing gasket 40 with holes on its surface, and a screw 30 inside the holes of the sealing gasket 40. A gasket 401 is annular with an inverted L-shaped cross-section. The gasket 401 fits snugly within the inner ring of the flange 20. A groove 402 is annular and corresponds to the position of a protrusion 502. A sealing gasket 50 is located on the bottom surface of the flange 10 and is annular with holes on its surface. A screw 30 inside the holes of the sealing gasket 50. The protrusion 502 is annular, and its end engages with the groove 402.

[0033] Flange 20 is installed on the inner wall of the pipe, with the top surface of flange 20 fitting against the inner wall of the pipe. At this time, flange 20 causes the end of gasket 2501 to fit against the inner wall of the pipe. Gasket 1401 is installed inside flange 20, so that gasket 1401 fits against the inner wall of flange 20. At this time, the end of gasket 2501 fits against the inner wall of the pipe, and the position of the groove 402 is staggered with the inner wall of the pipe.

[0034] Then, flange 10 is installed on the outside of the pipe, with the holes on the surfaces of flange 10 and flange 20 aligned vertically. At this point, the bottom surface of flange 10 is in contact with the pipe surface, and flange 10 causes gasket 2 50 to contact with the inner wall of the pipe. Simultaneously, gasket 2 501 is installed inside flange 10, and gasket 2 501 is in contact with the inner wall of flange 10. Gasket 2 501 then causes the level gauge probe to insert into the pipe. The level gauge probe enters the pipe from the groove in the center of gasket 1 40, and the bottom of gasket 2 501 is in contact with the pipe surface, with one side of gasket 2 501 in contact with the pipe's representative surface. At this point, the convex... Block 502 is placed inside the pipe opening. At this time, the end of the protrusion 502 is inserted into the inside of the slot 402. At the same time, the ends of gasket 1 401 and gasket 2 501 are in contact. The connection between gasket 1 401 and gasket 2 501 is sealed by the protrusion 502 and the slot 402. Gasket 1 401 and gasket 2 501 seal the inside of flange 1 10 and flange 2 20. The connection between flange 1 10 and flange 2 20 is sealed by sealing gasket 1 40 and sealing gasket 2 50. At this time, screw 30 is inserted into flange 10, causing flange 10 to rotate and be inserted into the pipe and flange 2 20, thus fixing the position of flange 1 10 and flange 2 20.

[0035] Working principle: When using the positive pressure sealing connection structure of this level gauge, screw 30, sealing gasket 40, gasket 401, and groove 402 are provided to facilitate the sealing of the device connection. Sealing gasket 50, gasket 501, and protrusion 502 are provided to seal the connection between flange 10 and flange 20 and the pipeline, increasing the overall practicality.
