Sealing medium absorption compensation device

Abstract

The invention discloses a sealing medium absorption compensation device and relates to the technical field of sealing rings. The sealing medium absorption compensation device specifically comprises abase and a filter mechanism; a sealing ring is installed inside the upper portion of the left wall of the base; a movable head is arranged below a first pressure sensor; the outer wall of the movablehead is fixedly connected with a sliding plate; a spring is horizontally arranged inside the movable head; a through hole penetrates through the base; the first pressure sensor and the movable head are both disposed inside the left wall of the base; a second pressure sensor is installed inside the lower portion of the left wall of the base; the right wall of the base is fixedly provided with a connector; and the filter mechanism is installed at the port end of the connector. With the sealing medium absorption compensation device, the problem of leakage of a sealing medium caused by abrasion tothe sealing ring during reciprocating motion of a motive seal can be effectively solved, thus, the purpose of protecting the sealing ring is achieved, production loss is reduced, and the overall production can be carried out smoothly. Meanwhile, the device is relatively simple in structure and has good practicability.

Description

technical field [0001] The invention relates to the technical field of sealing rings, in particular to a compensation device for sucking sealing medium. Background technique [0002] With the development of science and technology, domestic and foreign attach great importance to the research and development of sealing technology, and have achieved results, such as the "sock seal" device of Philip of the Netherlands and the new sliding sealing device of the Swedish United Stirling Engine Company. The latter has low cost and long life. [0003] There are many sealing methods. The most basic one is to seal with sealing rings, sealing rings, sealing plugs, etc. This type of sealing method is the best to achieve, and the cost is also lower than that of mechanical seals. The deformation of the structure makes the sealing effect very unstable and not durable. In order to solve this problem, on the dynamic seal of some structures, a spring or an O-ring will be installed on the outsi...

AI Technical Summary

Problems solved by technology

[0003] There are many sealing methods, the most basic one is to seal with sealing rings, sealing rings, sealing plugs, etc. This type of sealing method is best realized, and the cost is also lower than mechanical seals, but with sealing rings, sealing rings and other sealing bodies The structural deformation of the structure makes the sealing effect very unstable and not durable. In order to solve this problem, on the dynamic seal of some structures, a spring or an O-ring will be installed outside the sealing ring as a position compensation.

[0004] However, whether it is a spring or an O-ring, it will be deformed and fatigued under long-term compression, which greatly reduces the compensation effect, resulting in leakage and replacement at intervals, which increases the cost and is not conducive to long-term development.
