Description
Technical field
The utility model relates to sealing element technical fields, specifically with the mechanical sealing assembly of novel stationary seat.
Background technique
Mechanically-sealing apparatus is by least a pair of end face perpendicular to rotation axis in Fluid pressure and compensation mechanism elastic force
Under the action of and the cooperation of auxiliary seal under keep fitting, and the device for preventing fluid leakage constituted with respect to sliding.
Traditional mechanically-sealing apparatus is mainly by: end face seal pair (stationary seal ring and rotary packing ring), elastic element (such as bullet
Spring), auxiliary seal (such as O-ring), driving member (such as trundle and transmission screw), rotation preventing device (such as stop pin) and fastener (such as
Spring base, throw-out collar, gland, holding screw and axle sleeve) etc. composition.
In use, most of mechanical seals belong to contact seal.Its mechanism be by rotary packing ring with it is quiet close
The contact face of seal ring fits closely under the action of sealing-fluid pressure and elastic element pressing force, and reaches with respect to sliding
Sealing.Phenomena such as friction, sliding are with abrasion occurs when work, on mechanical seal end surface simultaneously, friction is its essential characteristic.Machine
The operating condition of tool seal face friction is generally divided into: fluid friction, mixed film friction and boundary friction three classes, but absolutely cannot be for a long time
Dry friction.
When seal face is in dry condition, direct contact is caused play by the surface of solids micro-bulge between both ends of the surface
Strong abrasion.Friction surface substance on the one hand can be made to lose or migrate when abrasion, lead to damaged surfaces；On the other hand it can generate big
The frictional heat of amount is until burn sealing.
Summary of the invention
The technical problem to be solved by the utility model is to provide the mechanical sealing assembly with novel stationary seat, stationary rings
Seat is equipped with several annular baffles, and annular baffle is equipped with spring, therefore increases and form runner in mechanical seal, is conducive to dissipate
Heat.
Technical solution adopted in the utility model is: it includes a retainer, is equipped with rotating seat and stationary ring in retainer
Seat, is respectively equipped with rotary packing ring and stationary seal ring on rotating seat and stationary seat, rotary packing ring and stationary seal ring palette and can
In relative rotation, the end face that rotary packing ring is bonded with stationary seal ring is respectively dynamic sealing face and static sealing surface, and stationary seat is equipped with
Several annular baffles, there is gap between annular baffle, and annular baffle end face is provided with through-hole, is equipped with spring, both ends of the spring in through-hole
It is respectively held against retainer and stationary seat.
Preferably, matrix is distributed on annular baffle end face through-hole in a ring.
Preferably, the number of openings in each annular baffle is two or more.
Preferably, sealing ring is equipped between rotating seat and rotary packing ring.
The mechanical sealing assembly with novel stationary seat of the utility model, advantage are as follows: stationary seat is equipped with several
Annular baffle, annular baffle is equipped with spring, therefore increases and form runner in mechanical seal, is conducive to heat dissipation.

Rotary packing ring 5 and 6 palette of stationary seal ring and can be in relative rotation, the end face that rotary packing ring 5 is bonded with stationary seal ring 6 be distinguished
For dynamic sealing face 7 and static sealing surface 8, sealing ring 12 is equipped between rotating seat 2 and rotary packing ring 5, stationary seat is equipped with several rings
Shape baffle 9 has gap between annular baffle 9, and 9 end face of annular baffle is provided with through-hole 10, is equipped with spring 11 in through-hole 10,
It being rotated when rotary packing ring 5 is driven by shaft, rotary packing ring 5 drives static friction ring 9 and stationary seal ring 6 to rotate,
Annular baffle 9 is fixed on stationary seat 3, and fixed form is welding or extends naturally from 3 side wall of stationary seat, each
Matrix is distributed on 9 end face of annular baffle through-hole 10 in annular baffle 9 in a ring, in the through-hole 10 of several annular baffles 9
Heart line is on same straight line, and spring 11 is installed in through-hole 10, and 11 both ends of spring are respectively held against retainer 1 and stationary ring
Seat 3, i.e. retainer 1 are fitted closely by spring 11 with stationary seat 3, and the through-hole 10 of all annular baffles 9 forms runner,
The utility model preferred embodiment is described above, but is not to be construed as limiting the scope of the invention.
The utility model is not only limited to above embodiments, and specific structure is allowed to vary, all in the utility model demand for independence
Made various change is within the protection scope of the present utility model in protection scope.
