Abstract
The utility model discloses a mechanical sealing device for a strong-corrosion resistant and abrasion-resistant Teflon corrugated pipe. The device comprises a static ring, a movable ring, a transmission bolt, a spring assembly, a corrugated pipe and a sub-division ring, wherein the section of the static ring is in a convex shape; the movable ring is tightly stuck on the left side surface of the static ring and forms sealing connection with the static ring; the corrugated pipe is arranged on the left side of the movable ring; the spring assembly is arranged on the outer side of the corrugated pipe; the right end of the spring assembly forms a groove; the movable ring is arranged in the groove; the sub-division ring is connected to the left ends of the spring assembly and the corrugated pipe; one side symmetric to the spring assembly is provided with a mounting hole; and a transmission bolt is arranged in the hole. In the mechanical sealing device, the Teflon corrugated pipe transmission is changed into a dual transmission structure of the Teflon corrugated pipe and the bolt pin to eliminate the hidden danger that a mode of adopting the corrugated pipe as a torque transmitting mode can not bear high temperature, the transmission bolt serves as a torque transmitting mode, the original corrugated pipe is only used for sealing, and the high temperature resistance performance of the product is improved.
Description
Technical field
The utility model relates to a kind of wear resistance PTFE-bellows mechanical seal device of being able to bear strong corrosion.
Background technique
At present on the market major applications be the filled polytetrafluoroethylene sealing surface, run into the strong corrosive medium that particle is arranged, sealing surface wearing and tearing fast causes the inefficacy of machine envelope; And variation along with the pump application area of matched host machine; Also often be applicable in the medium that contains particle; To the requirement of mechanical seal also along with raising; Present mechanical seal device for rubber bellows on the market all is to adopt the mode of bellows as transmitting torque, makes product aspect high temperature resistant, seem not enough.
Summary of the invention
The purpose of the utility model is to overcome the defective of existing technology, provides a kind of the wear resistance PTFE-bellows mechanical seal device of being able to bear strong corrosion polytetrafluoroethylbellows bellows and the dual drive mechanism of screw pin, resistant to elevated temperatures is changed in the polytetrafluoroethylbellows bellows transmission.
For realizing above-mentioned purpose; The utility model adopts a kind of wear resistance PTFE-bellows mechanical seal device of being able to bear strong corrosion, and PTFE-bellows mechanical seal comprises stationary ring, rotating ring, transmission screw, spring assembly, bellows, half point ring, and the stationary ring sectional shape is " protruding " type; Rotating ring is close to the left surface of stationary ring and is constituted motive sealing with stationary ring and is connected; Bellows is arranged on the left side of rotating ring, and said spring assembly is arranged on the outside of bellows, and the right-hand member of spring assembly forms a groove; Rotating ring is provided with in this groove; The adaptive left end that is connected spring assembly and bellows of said half point ring is provided with a mounting hole in the side with the spring assembly symmetry, and the transmission screw is arranged in this hole.
The utility model further is provided with again; Said spring assembly comprises spring seat, spring and latch bracket; Said latch bracket annular is arranged on the top, left side of bellows, and the sectional shape of latch bracket is " L " type, and the spring seat annular is arranged on the top, right side of bellows; The left end of spring seat offers a groove, and said spring is fixedly installed in the cavity that forms between latch bracket and the spring seat.
