Abstract
The utility model relates to a rubber corrugated tube pressure balancer which is a device for the pressure transmission and pressure balance between liquid media in two isolated cavities, in particular to a pressure balancer which is matched with a shaft mechanical sealing device for use. The rubber corrugated tube pressure balancer comprises a retaining bracket (1), a cover cylinder (2) and a rubber corrugated tube (3), wherein the front ends of the rubber corrugated tube (3) and the cover cylinder (2) are fixedly and hermetically connected with the retaining bracket (1), and the rubber corrugated tube (3) moves in the cover cylinder (2), the front end of the retaining bracket (1) is equipped with a threaded pipe orifice coupler (10) which is connected with a baffle plate (6), an isolated seal cavity is formed inside the rubber corrugated tube (3) which changes the volume of the inner cavity through extension and contraction, thereby transmitting and balancing the bilateral pressure, the moving resistance is small, the sealing property is excellent without leakage, the pressure loss is quite low and the use is safe and reliable.
Description
Technical field
The utility model relates to and be used for propagation of pressure, Equilibrator between segregate two chamber liquid mediums.Especially for fitted shaft (machinery) seal arrangement use to liquid medium pressure between the chamber, front and back that isolates transmit, Equilibrator.
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 axle (machinery) seal arrangement 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 ne-leakage, safe and reliable rubber corrugated pipe formula pressurizer.
The utility model includes fixed base, cover tube, rubber corrugated pipe tube formation, the front end and the fixed base of rubber corrugated pipe tube and cover tube are sealedly and fixedly connected, the front end of cover tube cooperates fixedly connected with the fixed base seam, the front end of rubber corrugated pipe tube is by the front end of cover tube and the seam fitting surface fixed seal connection of fixed base, the rubber corrugated pipe tube cooperates with cover tube inner chamber wall slip in the cover tube, on the ear end face of cover tube, have through hole, be provided with the threaded end (TE) joint at the front end of fixed base and fixedly connected, on the front-end face of fixed base, offer end-face seal ring with dividing plate.
When using, the utility model is installed on the dividing plate in two chambeies by fixed base, the rubber corrugated pipe tube forms the exclusion seal chamber, flexible its cavity volume that changes of rubber corrugated pipe tube, thereby transmission, balance pressure at both sides, its moving resistance is little, good airproof performance, ne-leakage, it is very little, safe and reliable that pressure loses damage.
