Abstract
Provided is a novel double mechanical seal member, comprising a movable ring, a static ring, a spindle sleeve, a spring, a spring seat, a gland and a sealing chamber. The center of the outer side of the spindle sleeve is fixedly provided with the spring seat. The spindle sleeves at two sides of the spring seat are respectively provided with a movable ring seat. The movable ring seat can conduct an axial motion with respect to the spring seat, and a spring is disposed between the spring seat and the movable ring seat. Two end faces of the sealing chamber are respectively provided with the gland. The housing of the sealing chamber is provided with a leakage recovering hole. The novel double mechanical seal member is advantageous in that a certain improvement is realized; a part of the structure is simplified; sealing performance is improved; structural innovation is achieved.
Description
Technical field
The utility model relates to the mechanical sealing technology field, specifically a kind of Novel double-end-face mechanical sealing element.
Background technique
Mechanical seal is by a pair of or several the end face of making relative sliding perpendicular to axle is kept applying and is equipped with auxiliary seal and reaches the gland seal device of Drain Resistance in that elastic force (or magnetic force) effect of hydrodynamic pressure and compensation mechanism is lower.It generally is comprised of elements such as stationary ring, rotating ring, elastic element, spring seat, Cock screw, auxiliary seal rings, and whether rotating ring and stationary ring can have the nose balance ability according to them toward contact is called compensated loop or non-compensation also.
The end face of rotating ring and stationary ring is fitted each other and is done the motive sealing of relative sliding, and it is the primary seal in the mechanical seal device, also is to determine mechanical sealing performance and the key in life-span.Therefore, very high to the processing request of seal face, keep necessary lubricating liquid film between seal face in order to make simultaneously, the compressive load per unit area on the end face processed of necessary strict chamber, pressure is excessive, is difficult for forming stable lubricating liquid film, can accelerate the wearing and tearing of end face; Pressure is too small, and leakage rate increases.So will obtain good sealability has again enough life-spans, when design and installation mechanical seal, must guarantee that end face compressive load per unit area value is in optimal scope.
The structure of the mechanical sealing element of present various Double End is complicated, and is high to making processing request, so the double mechanical seal spare of development of new structure has very real meaning.
The model utility content
The purpose of this utility model is to provide a kind of double mechanical seal spare of new structure, and can be widely used in muddy water, slurries etc. needs in the machinery of sealing.
The technical scheme in the invention for solving the technical problem is: a kind of Novel double-end-face mechanical sealing element, comprise rotating ring, stationary ring, axle sleeve, spring, spring seat, gland and gas-tight silo, and it is characterized in that,
Centre is fixed a spring seat in the outside of described axle sleeve, and a rotating seat is set respectively on the axle sleeve of described spring seat both sides, and described rotating seat can axially move with respect to spring seat, and between described spring seat and rotating seat a spring is installed;
The both ends of the surface of described gas-tight silo arrange respectively a gland, a stationary seat is fixed respectively in the inboard of described gland, match in the inboard of described stationary seat and the outside of described rotating seat, and on the junction plane at the place of matching of stationary seat and rotating seat, be inlaid with respectively stationary ring and rotating ring, form the cooperating structure of mechanical seal;
Housing at described gas-tight silo offers the leakage recovery holes.
Be provided with seal ring in the gap between described rotating seat and axle sleeve.
Be provided with seal ring in the gap between described stationary seat and gland.
Be provided with seal ring in the gap between described gland and gas-tight silo.
The beneficial effects of the utility model are: the utility model structure has certain improvement, has simplified part-structure, has improved sealability, and structure aspects has certain novelty.
Description of drawings
Fig. 1 is complete section schematic representation of the present utility model;
Among the figure: 1 rotating ring, 2 stationary rings, 3 axle sleeves, 31 screws, 4 springs, 5 spring seats, 6 glands, 7 gas-tight silos, 8 rotating seats, 9 stationary seats, 10 reveal recovery holes, 11 seal rings, 12 pins.
Embodiment
As shown in Figure 1,
A kind of Novel double-end-face mechanical sealing element comprises rotating ring 1, stationary ring 2, axle sleeve 3, spring 4, spring seat 5, gland 6 and gas-tight silo 7.
Axle sleeve 3 is parts commonly used of mechanical seal, and axle sleeve 3 is used for being sleeved on the collar of the axle that needs sealing, and the inboard shape of axle sleeve can be done suitable design according to the shape of axle.Be the main assembly department of mechanical seal in the outside of axle sleeve 3, fix a spring seat 5 in the outside of axle sleeve 3 centre by screw 31, spring seat 5 and axle sleeve one forward to axle sleeve.A rotating seat 8 is set respectively on the axle sleeve of spring seat 5 both sides, is socket connection between rotating seat 8 and the spring seat, rotating seat 8 can with respect to spring seat at the axial seat straight line motion, carry out the feeding of trace.A spring 4 is installed between spring seat 5 and the rotating seat 8, is played the effect of a pretightening force.
Gas-tight silo 7 is tubular bodies, and the gas-tight silo structure in the existing machinery sealing is similar.The both ends of the surface of gas-tight silo 7 arrange respectively a gland 6, connect by bolt between the two.A stationary seat 9 is fixed by pin 12 respectively in inboard at two glands 6, and stationary seat while and axle sleeve 3 match.Simultaneously, match in the inboard of stationary seat and the outside of described rotating seat, and on the junction plane at the place of matching of stationary seat 9 and rotating seat 8, be inlaid with respectively stationary ring 2 and rotating ring 1, so just formed the cooperating structure of a pair of mechanical seal.
Housing at described gas-tight silo offers leakage recovery holes 10.
For reaching two good sealing effects, be provided with seal ring 11 in the gap between rotating seat and axle sleeve, also be provided with seal ring in the gap between stationary seat and gland simultaneously.
Except the described technical characteristics of specification, be the known technology of those skilled in the art.
