Problems solved by technology
However, in the actual field, it is inconvenient to directly measure the size of the sealing groove, and it is impossible to determine the precise size of the inner diameter or outer diameter of the sealing gasket required. In addition, even if the sealing gasket is made according to the size of the sealing groove, due to the processing accuracy and other factors, the size of the sealing gasket and the sealing groove may not be completely matched. If the size is large, it will be difficult to assemble, and if the size is small, the sealing gap will be large, which will cause the strength of the sealing gasket to be insufficient and cause sealing. Can't achieve expected effect

Embodiment Construction
[0032] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0033] see figure 1 , figure 2 The gasket shown in Example 1 includes a gasket body 1 and an outer winding belt 2 wound on the outer periphery of the gasket body 1. The gasket body 1 includes an inner ring 12, a sealing Ring 11 , the outer winding tape 2 is spirally wound layer by layer on the outer side of the sealing ring 11 to form a multi-turn structure, and the innermost outer winding tape among the multiple turns of outer winding tape 2 is detachably connected to the sealing ring 11 . In this embodiment, the outer winding belt 2 adopts a metal winding belt, and two adjacent outer winding belts 2 are fixed to each other by multi-point welding, and the outermost end of the outer winding belt 2 can be directly pulled Strip 2 is removed layer by layer. Of course, the outer winding belt 2 can also be made of non-...

The invention discloses a sealing gasket with an adjustable positioning size. A plurality of circles of outer winding strips are wound around the side portions in the circumferential direction of the outer side of a gasket body to form a multi-circle structure layer by layer on the circumferential portion of the outer side of the gasket body, or a plurality of circles of inner winding strips are wound around the inner side of a center hole of the gasket body to form a multi-circle structure layer by layer on the circumferential portion of the inner side of the gasket body, so that during installation, an installer can suitably dismantle some outer winding strips or inner winding strips according to the matching situation of the gasket and a part to be installed, the outer diameter or inner diameter of the gasket is matched with that of the part to be installed, installation positioning of the gasket is more accurate, the gap in the sealing position is reduced, the strength of the sealing installation position is ensured, and the sealing effect of the gasket is improved.
Description
technical field [0001] The invention relates to a sealing gasket with adjustable positioning dimensions. Background technique [0002] There are pressure systems in nuclear power, oil refining, petrochemical, metallurgy, shipbuilding, energy and other industrial sectors. The working medium in these pressure systems is often high-temperature and high-pressure substances, or toxic and harmful high-risk chemicals. Therefore, the sealing of the pressure system appears to be particularly important. In a pressure system, a gasket is usually used to seal between two connected parts. When sealing, the gasket needs to be embedded in a sealing groove in the two connected parts. However, in the actual field, it is inconvenient to directly measure the size of the sealing groove, and it is impossible to determine the precise size of the inner diameter or outer diameter of the sealing gasket required. In addition, even if the sealing gasket is made according to the size of the sealing gr...
