Abstract
The utility model discloses a double-face mechanical seal without an auxiliary system. The double-face mechanical seal without the auxiliary system comprises a transmission sleeve, a shaft sleeve, an end cover combiner, a driving ring, a positioning ring, a fixed ring combiner and a movable ring combiner, wherein an O-shaped ring I and a non-compensation ring are installed on the end cover combiner, a spring, a push ring, an O-shaped ring II, a compensation ring and a snap ring I are installed on the transmission sleeve, the transmission sleeve is installed on the shaft sleeve by a jackscrew I, the non-compensation ring is contacted with the compensation ring, the fixed ring combiner is installed on the end cover combiner, an O-shaped ring VII is installed between the fixed ring combiner and the end cover combiner, the movable ring combiner is installed on the shaft sleeve, and an O-shaped ring VI is installed between the movable ring combiner and the shaft sleeve. The double-face mechanical seal solves the problems that the auxiliary device can not be connected at site, and the requirement on the leakage amount is strict, and furthermore, compared with a common double-face mechanical seal, the double-face mechanical seal has the advantages that the axial size is small, the structure is simple, and the realization is convenient.
Description
Technical field
The utility model relates to the double mechanical seal field, relates in particular to a kind of not with the double mechanical seal of auxiliary system.
Background technique
Double mechanical seal has remarkable advantages than single mechanical end face seal aspect the control media leakage rate.But double mechanical seal need dispose auxiliary system, so that atmospheric side mechanical seal has sealing liquid lubricated, avoids dry friction.But the many times on-the-spot condition that does not possess the auxiliary system of connecing requires relatively strictness to mechanical sealing leakage amount again, thereby has caused mechanical seal to be difficult for realizing, has influenced the effect of mechanical seal.
The model utility content
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of not with the double mechanical seal of auxiliary system.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of not with the double mechanical seal of auxiliary system; Comprise drive sleeve, axle sleeve, end cap combination, driving ring, location piece, stationary ring combination and rotating ring combination; In the described end cap combination O shape circle one, uncompensated ring are installed, spring, throw-out collar, O shape circle two, compensated loop, snap ring one are installed on the described drive sleeve, described drive sleeve is installed on the axle sleeve through jackscrew one; Described uncompensated ring contacts with compensated loop; Described location piece is installed in driving ring, and is installed in the end cap combination through hexagon head bolt, and described driving ring is installed on the axle sleeve through jackscrew two; Described stationary ring stack mounting is in the end cap combination; Between stationary ring combination and the end cap combination O shape circle seven is installed, described rotating ring stack mounting is equipped with O shape circle six between rotating ring combination and the axle sleeve on axle sleeve.
Described rotating ring combination is installed on the axle sleeve through snap ring two.
Be provided with labyrinth seal, O shape circle five between described stationary ring combination and the rotating ring combination.
The utility model has solved the on-the-spot condition that does not possess the auxiliary system of connecing, but leakage rate is required relatively stricter again problem, and this double mechanical seal is littler than the axial dimension of general double mechanical seal, simple in structure, and it is convenient to realize.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1, O shape encloses 1, uncompensated ring 3, compensated loop 4, snap ring 1, O shape enclose 26, throw-out collar 7, spring 8, drive sleeve 9, jackscrew 1, axle sleeve 11, O shape enclose 3 12, end cap combination 13, O shape enclose 4 14, stationary ring combination 15, rotating ring combination 16, snap ring 2 17, driving ring 18, jackscrew 2 19, location piece 20, hexagon head bolt 21, O shape enclose 5 22, O shape encloses 6 23, O shape circle seven.
Embodiment
As shown in Figure 1; A kind of not with the double mechanical seal of auxiliary system, comprise drive sleeve 8, axle sleeve 10, end cap combination 12, driving ring 17, location piece 19, stationary ring combination 14 and rotating ring combination 15, be equipped with in the described end cap combination 12 that O shape encloses 1, uncompensated ring 2; Be equipped with on the described drive sleeve 8 that spring 7, throw-out collar 6, O shape enclose 25, compensated loop 3, snap ring 1; Described drive sleeve 8 is installed on the axle sleeve 10 through jackscrew 1, and described uncompensated ring 2 contacts with compensated loop 3, and described location piece 19 is installed in driving ring 17; And be installed in the end cap combination 12 through hexagon head bolt 20; Described driving ring 17 is installed on the axle sleeve 10 through jackscrew 2 18, and described stationary ring combination 14 is installed in the end cap combination 12, between stationary ring combination 14 and the end cap combination 12 O shape is installed and encloses 7 23; Described rotating ring combination 15 is installed on the axle sleeve 10 through snap ring 2 16, between rotating ring combination 15 and the axle sleeve 10 O shape is installed and encloses 6 22; Described stationary ring combination 14 and rotating ring are provided with labyrinth seal between making up 15, O shape encloses 5 21; Described end cap combination 12 is installed on the equipment through stud bolt, between end cap combination 12 and the equipment O shape is installed and encloses 4 13; Between described axle sleeve 10 and the axle O shape is installed and encloses 3 11.
During equipment operation, the side medium primary seal seals, and the sealing surface of the secondary sealing of atmospheric side does not contact, and rotating ring combination 15 is along with axle rotates together, and stationary ring combination 14 is not rotated; The Seal cage internal pressure of primary seal is a pressure medium, is higher than atmospheric pressure, and the Seal cage pressure of secondary sealing is atmospheric pressure.If primary seal is damaged; Then pressure medium gets into auxiliary seal cavity; Between stationary ring combination 14 and rotating ring combination 15, labyrinth seal is arranged, pressure can not reduced, rapidly under the effect of pressure medium; Stationary ring combination 14 overcomes O shape and encloses 7 23 resistance and the new friction pair of rotating ring combination 15 compositions, plays seal action.
