Abstract
The utility model discloses a novel mechanical axis is sealed device, including end cover, quiet ring, friction ring, rotating ring, spring, spring holder, casing, mechanical axis and linkage bolt, bolted connection is between the screw hole and rotating ring of spring holder in the linkage, and the spring lies in between rotating ring and the spring holder and lies in one side of mechanical axis, and the cross -section tip of rotating ring is provided with the recess, and recess and suit that the friction ring lies in the rotating ring are outside the mechanical axis, and quiet ring suit mechanical axis is outer and near the friction ring, and end cover suit fixed connection outside quiet ring compares with prior art, the utility model discloses the spring makes zonulae occludens between rotating ring, friction ring and the quiet ring, when remaining inseparable laminating after the friction ring wearing and tearing between effect messenger's rotating ring through the spring and the friction ring throughout to can improve whole sealing device's life, improve the gas tightness, prevent that gas or liquid from leaking, convenient to use has the value of popularization and application.
Description
Technical field
The utility model relates to a kind of mechanical seal device, particularly relates to a kind of novel mechanical shaft sealer.
Background technique
Mechanical seal is a kind of gland seal device of rotating machinery.The equipment such as such as centrifugal pump, centrifuge, reactor and compressor.Because transmission shaft is applied in inside and outside equipment, like this, there is a circumferential clearance between axle and equipment, medium in equipment passes through this gap to external leakage, if equipment internal pressure is lower than barometric pressure, then air is to equipment internal leakage, and one therefore must be had to stop the gland seal device leaked.The kind of shaft seal is a lot, the advantage such as to grow, so mechanical seal is in the topmost shaft sealing mode of these equipment in the world because mechanical seal has leakage rate few and life-span.In prior art, after sealed member wearing and tearing, still easily occur leakage phenomenon for mechanical shaft seal, working life is short, there is room for improvement.
Model utility content
The purpose of this utility model is just to provide a kind of novel mechanical shaft sealer to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises end cap, stationary ring, friction ring, rotating ring, spring, spring seat, housing, mechanical axis and interlock bolt, it is outer and be fixedly connected with that described spring socket sleeve is loaded on described mechanical axis, the side of described spring seat is provided with tapped hole, described moving ring sleeve is loaded on described mechanical axis outward also can be movable along axis, described interlock bolt is connected between the tapped hole of described spring seat and described rotating ring, described spring is between described rotating ring and described spring seat and be positioned at the side of described mechanical axis, the end, cross section of described rotating ring is provided with groove, described friction ring is positioned at the groove of described rotating ring and is set in outside described mechanical axis, it is outer and near described friction ring that described stationary ring is set with described mechanical axis, it is outer and be fixedly connected with that described end cap is set in described stationary ring, one end of described housing be fixed on described end cap side and by described stationary ring, described friction ring, described rotating ring, described spring, described spring seat, in described mechanical axis and described interlock bolt are coated on.
Particularly, be connected by fixing bolt between described spring seat with described mechanical axis; Be provided with stationary ring seal ring between described end cap and described stationary ring, between described end cap and described housing, be provided with end bracket enclosed circle.
The beneficial effects of the utility model are:
The utility model is a kind of novel mechanical shaft sealer, compared with prior art, the utility model spring makes rotating ring, compact siro spinning technology between friction ring and stationary ring, fit tightly when making to remain between rotating ring and friction ring by the effect of spring after friction ring wearing and tearing, thus the working life of whole seal arrangement can be improved, improve tightness, prevent gas or leak of liquid, easy to use, there is the value applied.
Accompanying drawing explanation
