Gas holder piston oil groove separating weir

Abstract

The invention discloses a gas holder piston oil groove separating weir, which comprises a weir part slide plate, a weir part separating plate and a sealing element clamping mechanism, wherein the lower end of the weir part slide plate is fixedly arranged on the sealing element clamping mechanism, the upper end of the weir part slide plate is higher than the upper end of the weir part separating plate, a supporting rod arranged along the radial direction of a piston is fixedly connected onto the position, higher than the weir part separating plate, of the weir part slide plate, a guide block with a position limiting groove is arranged on the upper end of the weir part separating plate, and the supporting rod is inserted into the position limiting groove and is in slide matching with the position limiting groove. The gas holder piston oil groove separating weir has the advantages that a supporting point is provided for the upper end of the weir part slide plate through the heightening of the weir part slide plate and the arrangement of the supporting rod and the guide block, so the capability of the weir part slide plate for bearing the oil level difference pressure at two sides of weir part canvas is enhanced, the capability of resisting the pressure in the radial direction of the piston is also enhanced, further, the problems of piston inclination standard exceeding and gas leakage can be effectively avoided, in addition, the pressure of a balance weight lever pressing mechanism on the weir part slide plate can be reduced, and the friction abrasion of the weir part slide plate is reduced.

Description

technical field [0001] The invention relates to a gas cabinet, in particular to an oil ditch separation weir of the gas cabinet. Background technique [0002] The piston oil groove of the thin oil-sealed gas holder sealing device currently used is equipped with a piston oil groove separation system. The piston oil groove separation system is composed of a plurality of sets of sealing oil separation weirs that are basically symmetrically distributed to prevent The one-sided phenomenon of sealing oil can avoid the piston tilting beyond the standard and even gas leakage. With the development of thin oil-sealed gas tanks to high pressure, the sealing oil stored in the piston oil ditch is getting higher and higher, and the oil level difference pressure of the piston oil ditch separation weir is also increasing. The safety of the piston oil ditch separation weir is also increasing. Stable long-term operation has become a frontier research topic in the industry. [0003] Patent N...
