Abstract
The utility model relates to a corrugated sleeve diaphragm type pressure balancer, in particular to a pressure balancer which is matched with a shaft mechanical sealing device to transfer and balance pressure of liquid medium among isolation cavities. The corrugated sleeve diaphragm type pressure balancer comprises a rubber corrugated sleeve (1), an internal support pressing ring (2) and an external support pressing ring (3), wherein the front edge of the rubber corrugated sleeve (1) and a cavity baffle (4) are tightly sealed and fixedly connected through the internal support pressing ring (2) and the external support pressing ring (3). The corrugated sleeve diaphragm type pressure balancer has excellent sealing performance, simple manufacture and safe and reliable use.
Description
Technical field
The utility model relates to and be used for propagation of pressure, Equilibrator between segregate two chamber liquid mediums.Particularly the fitted shaft mechanical seal device use to liquid medium pressure between separate cavities transmit, the pressurizer of balance.
Background technique
In some device or equipment, need the pressure medium of a chamber liquid is delivered on the other chamber liquid medium, and the liquid medium in two chambeies cannot mix.Concrete application facet as; Development along with technology, seal request to rotatingshaft is more and more higher, the pressure reduction at mechanical seal for axle two ends is big more, influence and requirement to shaft sealer are just big more, and the pressure balance side that makes the shaft sealer two ends can alleviate the requirement to shaft sealer greatly, and this just needs a kind of structure and pressurizer is realized this propagation of pressure, promptly guarantees seal arrangement front and back cavity pressure balance, mind not produce mixing that it is less to make pressure lose damage simultaneously for two kinds.
The model utility content
The purpose of this utility model provides a kind of good airproof performance, uses reliably, makes easy, safe and reliable radiation fins diaphragm type pressurizer.
The utility model is made of rubber bellows set, interior ring bearing trim ring, outer shroud trim ring, the front edge of rubber bellows set is compressed by interior ring bearing trim ring and outer shroud trim ring and chamber dividing plate and is sealedly and fixedly connected, and corresponding rubber bellows set circle distribution on the dividing plate of chamber offers through hole.
The utility model fitted shaft mechanical seal device uses, to liquid medium pressure between separate cavities transmit, balance, the liquid medium of chamber dividing plate one side enters in the rubber bellows set by the through hole of offering on the dividing plate of chamber, rubber bellows set is the flexible volume that changes under the medium pressure liquid effect, thereby transmits, the balance pressure at both sides.Its good airproof performance, the pressure loss is little, make easy, safe and reliable flexible free because the rubber bellows set space outerpace is open, can better adapt to the many and sticky medium of granule foreign in the medium, can not form and block the balace weight mobile working.
