Abstract
The utility model relates to a seal box, in particular to a metal spring embedded seal box, which mainly solves the technical problems of low processing precision, easy aging, short storage time, short service life, poor bearing pressure and easy occurrence of inside medium leakage caused by metal aging existing in a traditional filling seal box. The utility model adopts the technical scheme that: the metal spring embedded seal box comprises a sealing ring and a supporting ring, and is characterized in that the supporting ring is a metal spring. The sealing ring is drilled with an O-shaped notch or a V-shaped or U-shaped notch, the shape of the metal spring is matched with the notch of the sealing ring and is a spiral O-shaped spring or a V-shaped or U-shaped spring formed by curling a metal flat bar. The utility model is mainly used for the sealing of the connected parts of valves, pumps and flanges of large marine power machines, other heavy industrial machines and the like and the dynamic sealing of hydraulic cylinders, cylinders and the like.
Description
Technical field:The utility model relates to a kind of sealed letter, particularly a kind of metal spring insert seal letter.Be mainly used in the dynamic seal of the sealing of valve, pump, flange connections of large ship dynamic power machine and other heavy industry machineries etc. and oil hydraulic cylinder, cylinder etc.
Background technique:The sealing of dynamic power machines such as present large ship is generally adopted the filled type sealed letter, working medium: power diesel oil or other class machinery oil; Operating temperature :-20～200 ℃; Working pressure: 0～35.0MPA; Operating time: 2000～4000H; Because working medium and operating conditions are relatively harsher, the high temperature resistant non-metal part of general employing, with reference to Fig. 1, snap in nonmetallic ring in seal ring 1, described nonmetallic ring is a rubber ring 3, but there is following defective in nonmetallic ring: machining accuracy is low and easily aging, storage time is short, working life is short, and bearing capacity is poor, and the technical problem that causes interior media to leak after nonmetal the wearing out takes place easily.Thereby the maintenance, repair cost that increases the weight of equipment reduces the utilization efficiency of machinery equipment, even cause serious equipment and human injury.So seeking alternative is a job highly significant.
The model utility content:The purpose of this utility model provides the metal spring insert seal letter that a kind of energy substitutes traditional nonmetal filling sealed letter.Mainly solve existing tradition and enrich that the machining accuracy that sealed letter exists is low, working life short, bearing capacity is poor, and the nonmetal technical problem that causes interior media to leak after aging takes place easily.
The technical solution of the utility model is: a kind of metal spring insert seal letter, comprise seal ring and support ring, and it is characterized in that: described support ring is a metal spring.Described seal ring has O type notch or notch is V or U type, described metal spring profile and seal ring notch coupling, the spiral O type spring, V-type or the U type spring that form for the metal flat crimped.
The beneficial effects of the utility model are: the machining accuracy height, and the storage time is long, and long service life is difficult for wearing out, and bearing capacity is stable, and is pollution-free environmental.Its practical life-span is much higher than nonmetal packing ring.And can reduction equipment and human injury.
