Abstract
The utility model relates to a piston type pressure balancer, in particular to a pressure balancer which is matched with a shaft mechanical sealing device for transmitting and balancing the pressures of liquid media in two isolated cavities. The piston type pressure balancer comprises a piston cylinder (1), a piston (2) and a piston rod (3), wherein the front end of the piston cylinder (1) is equipped with a threaded pipe orifice coupler (4) which is fixedly connected with a cavity baffle plate (9), the front end face of the piston cylinder (1) is provided with an end face sealing ring (6), and the rear end face thereof is provided with a through-hole (5). The pressures of the liquid media at two sides of the piston drive the piston to move form side to side for transmitting and balancing bilateral pressures. The piston type pressure balancer has excellent sealing property, simple and convenient 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 piston-type pressure balace weight.
The utility model is made of piston cylinder, piston, piston rod, being provided with the threaded end (TE) joint at the front end of piston cylinder fixedlys connected with the chamber dividing plate, piston rod penetrates in the threaded end (TE) joint endoporus and supports stable plunger, on the ear end face of piston cylinder, have through hole, on the front-end face of piston cylinder, offer end-face seal ring.
Piston cylinder was installed on the dividing plate in two chambeies by its threaded end (TE) joint when the utility model used, the liquid medium of dividing plate one side enters piston cylinder by threaded end (TE) joint endoporus, the liquid medium of opposite side enters the opposite side of piston cylinder inner carrier by the through hole of offering on the piston cylinder ear end face, piston both sides medium pressure liquids promotes the piston move left and right, thereby transmits, the balance pressure at both sides.Its good airproof performance is made easy, safe and reliable.
