Description
Technical field
The utility model relates to mechanically-sealing apparatus, more particularly to a kind of carborundum mechanical seal throttling dress
Put.
Background technology
When rinsing single mechanical end face seal, needing to separate flushing liquor with air, commonly used axial length is short herein
Throttling arrangement simple seal is carried out to flushing liquor, at present conventional throttling arrangement is rectangle restrictor ring and labyrinth seal, rectangle
Restrictor ring leans on small gap stable between rotatable parts to seal, and the less sealing effectiveness in gap is better, i.e. the jump to rotatable parts
Dynamic requirement is higher, and leakage rate is bigger.Labyrinth seal is in addition to needing stable small-gap suture, in addition it is also necessary to process multiple on cavity
Rectangular recess, and wear-out failure will be caused to labyrinth seal when rotatable parts are beated bigger.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of requirement of beating is low, the carborundum machine of length in service life
Tool sealing throttling arrangement.
Technical solution of the present utility model is to provide a kind of carborundum mechanical seal throttling with following structure
Device, coordinates and the spacing lip ring on axle of circumference and restrictor ring including seal, and described restrictor ring is relatively and axle
Face be provided with cannelure, described lip ring is rotatably assorted in cannelure, is provided with between described restrictor ring and axle
One gap.
Preferably, it is provided with the second gap between described cannelure bottom land and lip ring.
Preferably, it is provided with third space between described cannelure sidewall and lip ring.
Preferably, described lip ring is elastic component.
Preferably, described lip ring and axle interference fit.
Preferably, described lip ring is provided with some annular protrusions, and described restrictor ring is provided with multiple and convex annular
Act the cannelure matching.
Preferably, it is provided with lubricant between described lip ring and cannelure.
Preferably, described cannelure cross sectional shape is rectangle, and described lip ring cross sectional shape is circle.
After using above structure, carborundum mechanical seal throttling arrangement of the present utility model, compared with prior art, tool
Having the advantage that described restrictor ring is arranged on axle and playing simple seal, described lip ring not only seals cooperation and exists
Match on axle and with restrictor ring interior annular groove and form the structure of similar labyrinth seal, i.e. form some gaps of damming, be situated between by sealing
Matter by tortuous dam gap when produce throttle effect thus reach to seal, owing to being coordinated with cannelure by restrictor ring,
Make between restrictor ring and axle, to be provided with the first gap, greatly reduce requirement of beating, and lip ring is directly rotatably assorted at ring
In shape groove, simple and stable structure, not easy to wear.
Brief description
Fig. 1 is the cross-sectional view of carborundum mechanical seal throttling arrangement of the present utility model.
Shown in figure: the 1st, axle；2nd, lip ring；3rd, restrictor ring；31st, cannelure；4th, the first gap；5th, the second gap；
6th, third space.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Refer to shown in Fig. 1, carborundum mechanical seal throttling arrangement of the present utility model, coordinate and circumference including seal
Spacing lip ring 2 on axle 1 and restrictor ring 3, relative and axle 1 the face of described restrictor ring 3 is provided with cannelure 31, institute
The lip ring 2 stated is rotatably assorted in cannelure 31, is provided with the first gap 4 between described restrictor ring 3 and axle 1, described
Restrictor ring 3 is arranged on axle 1 and can play simple seal, described lip ring 2 not only seal cooperation on axle 1 and with throttling
Ring 3 interior annular groove 31 matches and forms the structure of similar labyrinth seal, i.e. forms some gaps of damming, and sealed medium is by song
Folding dam gap when produce throttle effect thus reach seal, owing to being coordinated with cannelure 31 by restrictor ring 3, make restrictor ring
It is provided with the first gap 4 between 3 and axle 1, greatly reduces requirement of beating, and lip ring 2 is directly rotatably assorted at cannelure
In 31, simple and stable structure, not easy to wear, it is provided with the second gap 5 between described cannelure 31 bottom land and lip ring 2,
It is i.e. provided with the space moved for lip ring 2, it is allowed to lip ring 2 has beats more greatly, reduce further requirement of beating,
And axle 1 will not produce extra frictional force due to cannelure 31 and lip ring 2 conflict when beating, make operation more steady
Fixed.
Described lip ring 2 is rotatably assorted in cannelure 31, for reducing joining of lip ring 2 and cannelure 31
Occlusal wear and facilitate lip ring 2 to rotate, can several can be implemented in combination with by a kind of in following several ways, described annular
Seal 2 is elastic component, i.e. can be with snap-fit cannelure 31 inside dimension, and the license amount that a certain degree of increase axle 1 is beated,
Ensure that between lip ring 2 and cannelure 31, frictional force maintains lesser extent；Described cannelure 31 sidewall and annular
It is provided with third space 6 between seal 2, i.e. ensure not produce frictional force between lip ring 2 and cannelure 31, reduce mill
Damage, improve service life further；It is provided with lubricant, it is ensured that ring packing between described lip ring 2 and cannelure 31
Between part 2 and cannelure 31, frictional force maintains lesser extent.
Described lip ring 2 and axle 1 interference fit, make lip ring 2 be stably fixed on axle 1, and structure
Simple and stable, described lip ring 2 is provided with some annular protrusions, and described restrictor ring 3 is provided with multiple with annular protrusion phase
The cannelure 31 joined, is i.e. provided with the structure of the similar labyrinth seal of many groups, is overlapped mutually and considerably increases sealing effectiveness.
Described cannelure 31 cross sectional shape is rectangle, and described lip ring 2 cross sectional shape is circle, produces simple,
And conveniently arrange lip ring 2 interior with cannelure 31 and ensure sealing effectiveness, and cannelure 31 contacts with lip ring 2
Face is less, weares and teares less, improves service life.
Lip ring 2 is made up of the thermoplastic with filler, such as polytetrafluoroethylene (PTFE), and polytetrafluoroethylene (PTFE) has non-
Often good chemical resistance, preferably as this thermoplastic, additionally the polytetrafluoroethylene (PTFE) of filled glass fiber has relatively low
Thermal coefficient of expansion, higher intensity, anti-cold deformation, preferably as matrix material.The polytetrafluoroethyl-ne of other filling carbon fiber
Alkene has higher lubricity, preferably as lip ring 2 material, reduces the friction of O RunddichtringO and rectangular recess
Loss, when lip ring 2 blocks with cannelure 31, lip ring 2 can slide with cannelure 31, and same guarantee seals,
This kind of design considerably increases the reliability of device.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonging under the utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, under the premise of without departing from the utility model principle some improvement and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
