Abstract
A corrugated tube pressure balancer of the utility model is a device used for the pressure transmission and pressure balance between liquid media in two isolated cavities, which comprises a retaining bracket (1), a cover cylinder (2), a corrugated tube (3) and a movable plate (4), wherein the movable plate (4) is slidably matched with the inner cavity wall of the cover cylinder inside the cover cylinder (2), the front end of the retaining bracket (1) is provided with a threaded pipe orifice coupler (10) which is fixedly connected with a baffle plate (6), the corrugated tube (3) and the movable plate (4) form an isolated seal cavity, the corrugated tube is extended or contracted to match with the movement of the movable plate for changing the volume of the inner cavity, 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.As be used for liquid medium propagation of pressure Equilibrator between chamber, front and back that pump shaft sealing device isolates.
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 shaft sealer 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, bellow type pressurizer when safe and reliable.
The utility model includes fixed base, cover tube, bellows, shifting board, fixedly connected with the shifting board welded seal with fixed base respectively in the front end and back end of bellows, the front end of cover tube is fixedlyed connected with the fixed base welded seal, shifting board 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, installs on the dividing plate in two chambeies the utility model by fixed base, bellows and shifting board form the exclusion seal chamber, the flexible shifting board that cooperates of bellows moves its cavity volume of change, 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.
