Description

Technical Field

[0001] The utility model belongs to the field of thin oil sealed gas cabinets, and in particular relates to a thin oil sealed gas cabinet piston guide wheel force monitoring structure. Background Art

[0002] When the oil-sealed gas tank is in operation, the piston rises and falls dynamically with the gas storage volume. The guide wheel group installed around the piston slides up and down along the inner side of the gas tank column during the piston lifting process, guiding the piston lifting and lowering, so that the piston rises and falls smoothly. The guide wheel must maintain a moderate contact pressure with the gas tank side panel. When the contact pressure is too small or the gap between the guide wheel and the gas tank side panel is too large, it will cause the piston to tilt and affect the sealing of the piston. When the contact pressure is too large, the outward squeezing force on the gas tank side panel during the lifting process can easily cause cracks in the joints and welds of the gas tank side panels, thereby causing gas tank leakage, sealing oil leakage, etc., which can easily lead to safety accidents.

[0003] To solve the above problems, patent document 204437674U discloses a self-tightening piston gas tank, which belongs to the field of gas storage tank technology and includes a gas tank cylinder and a piston. It is characterized in that it also includes at least one set of self-locking sealing components arranged between the gas tank cylinder and the piston, a traction device that guides the up and down movement of the self-locking sealing components, and a fixing device that fixes the sealing components on the piston. The self-tightening sealing component includes a sealing belt, a sealing belt pressure plate, a "U" or "C" shaped membrane, and a baffle. The "U" or "C" shaped membrane opens downward, and the sealing belt pressure plate and baffle are respectively arranged on both sides of the "U" or "C" shape. However, it cannot solve the above problems. Utility Model Content
