Abstract
The utility model discloses a kind of self-equilibrating stresses mechanical seal device, solve mechanical seal device and to work in the environment that medium pressure liquid is larger flimsy problem.Also include gland and stuffing box gland, described stationary seat, rotating seat, gland and stuffing box gland form resistance sealing liquid cavity, and stuffing box gland offers liquid filling hole, and this liquid filling hole is combined with corresponding plug; Also be combined with stepped sealing push ring near between the rotating ring and rotating seat of impeller end, this stepped sealing push ring is also combined with corresponding goring push spring between rotating seat; Described stepped sealing push ring and rotating seat cooperation place are also provided with rubber seal.Self-equilibrating stresses mechanical seal device of the present utility model, by the effect of goring push spring, stepped sealing push ring etc., during use, whole device is in media fluid, media fluid enters in the stepped cavity of stepped sealing push ring, namely on the left of rotating ring, rotating ring left and right sides dielectric fluid is communicated, the pressure produced offsets, and prevents rotating ring to be only subject to right side pressure medium and deformed damaged.
Description
Technical field
The utility model relates to a kind of seal arrangement, and particularly a kind of autobalance medium pressure liquid of being mainly used in when pressure medium is greater than resistance water shutoff pressure is to reduce the self-equilibrating stresses mechanical seal device of mechanical deterioration.
Background technique
Self-equilibrating stresses mechanical seal device is applicable to the industry that the discharge pressure such as mine, metallurgy is high, dielectric solid granule density is large, because the industry such as mine, metallurgy water resources lacks, the resistance water shutoff pressure be equipped with can not meet the usage requirement of mechanical seal, often causes sealing surface to be pushed open by pressure medium and affects mechanical seal working life.The mechanical seal of current use is the common double end-face structure form of resistance water shutoff pressure higher than medium pressure liquid, when hindering water shutoff pressure for a certain reason lower than medium pressure liquid, sealing surface is easily pushed open by medium pressure liquid, produce heavy wear phenomenon, make the mechanical seal life-span shorter, user's usage requirement can not be met.
Model utility content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is: provide a kind of autobalance medium pressure liquid to reduce the self-equilibrating stresses mechanical seal device of mechanical deterioration.
In order to achieve the above object, the utility model is achieved through the following technical solutions: self-equilibrating stresses mechanical seal device, comprise rotating shaft and be sleeved on the axle sleeve in this rotating shaft, axle sleeve is provided with stationary seat and rotating seat from left section and right section, and stationary seat is combined with corresponding stationary ring, rotating seat is combined with corresponding rotating ring, and described rotating shaft right-hand member is connected with impeller; Also include gland and stuffing box gland, described stationary seat, rotating seat, gland and stuffing box gland form resistance sealing liquid cavity, and stuffing box gland offers liquid filling hole, and this liquid filling hole is combined with corresponding plug; Also be combined with stepped sealing push ring near between the rotating ring and rotating seat of impeller end, this stepped sealing push ring is also combined with corresponding goring push spring between rotating seat; Described stepped sealing push ring and rotating seat cooperation place are also provided with rubber seal.
Between described gland and stationary seat, between gland and stuffing box gland and between axle sleeve and impeller, be provided with rubber seal.
The beneficial effects of the utility model are: self-equilibrating stresses mechanical seal device of the present utility model, by the effect of goring push spring, stepped sealing push ring etc., during use, whole device is in media fluid, media fluid enters in the stepped cavity of stepped sealing push ring, namely on the left of rotating ring, rotating ring left and right sides dielectric fluid is communicated, the pressure produced offsets, and prevents rotating ring to be only subject to right side pressure medium and deformed damaged.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, self-equilibrating stresses mechanical seal device of the present utility model, the axle sleeve 2 comprising rotating shaft 1 and be sleeved in this rotating shaft 1, axle sleeve 2 is provided with stationary seat 10 and rotating seat 4 from left section and right section, and stationary seat 10 is combined with corresponding stationary ring 14, rotating seat 4 is combined with corresponding rotating ring 13, and described rotating shaft 1 right-hand member is connected with impeller 11; Also include gland 3 and stuffing box gland 9, described stationary seat 10, rotating seat 4, gland 3 and stuffing box gland 9 form resistance sealing liquid cavity, and stuffing box gland 9 offers liquid filling hole 8, and this liquid filling hole 8 is combined with corresponding plug; Also be combined with stepped sealing push ring 12 near between the rotating ring 13 of impeller 11 end and rotating seat 4, this stepped sealing push ring 12 to be also combined with corresponding goring push spring 6 between rotating seat 4; Described stepped sealing push ring 12 is also provided with rubber seal 7 with rotating seat 4 cooperation place.Self-equilibrating stresses mechanical seal device of the present utility model, by the effect of goring push spring 6, stepped sealing push ring 12 etc., during use, whole device is in media fluid, media fluid enters in the stepped cavity of stepped sealing push ring 12, namely on the left of rotating ring 13, rotating ring 13 left and right sides dielectric fluid is communicated, the pressure produced offsets, and prevents rotating ring 13 to be only subject to right side pressure medium and deformed damaged.It should be noted that the resistance sealing liquid in resistance sealing liquid cavity coordinates reasoning spring 6 to keep the sealing of rotating ring 13 and stationary ring 14.
As preferably, between described gland 3 and stationary seat 10, between gland 3 and stuffing box gland 9 and between axle sleeve 2 and impeller 11, be provided with rubber seal 7, improve sealability, extend the working life of whole device.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
