Description
Technical field
The present invention relates to a kind of sealing device, particularly compensates the sealing device of wear extent automatically.
Background technology
Traditional sealing device does not have the wear extent automatic compensation function of sealing medium, i.e., after an action of the bowels
Newly to devise the sealing device of some belt wear amounts compensation, but it is substantially all and adopts spring compression
Mode, practical effect is undesirable；Simple spring compression type sealing device operation principle
It is to make airtight and watertight padding be fitted tightly over equipment surface using spring force to form sealing, while in bullet
The wear extent of compensation sealing filler in the range of the design runlength of spring, the elastic force and stroke of spring are shadows
The sealing effectiveness and the key factor of airtight and watertight padding replacement cycle of sealing device are rung, what spring was provided
Elastic force scope reasonable interval is fixed, and elastic force crosses the abrasion that conference accelerates airtight and watertight padding, elastic force
It is too small, effectively sealing cannot be realized；Simultaneously the volume of sealing device is difficult excessive, the chi of spring
There is limitation in very little selection；It is simple using the close of spring structure used in actual production at present
Seal apparatus, early stage can be sealed effectively, but when airtight and watertight padding wear extent is more than spring design row
When journey, then cannot continue the sealing thrust for obtaining spring, sealing effectiveness deteriorates, so that
In seal failure, in order to ensure sealing effectiveness, airtight and watertight padding needs frequently to change, and utilization rate is low,
Conventional sealing apparatus cannot for a long time maintain good sealing；Conventional sealing apparatus are in actual production
Produce many problems：First, frequently changing filler needs equipment frequently to stop transport, and causes equipment
Running rate is low, less economical；Secondly, it is impossible to which whether anticipation sealing fails, can only lose in sealing
Airtight and watertight padding is changed after effect, material from leakage may cause the severe thing such as environmental pollution and personnel's injury
Therefore；Again, repeated disassembled and assembled, maintenance workload is very big；Finally, airtight and watertight padding utilization rate is low,
Need substantial amounts of filler spare part.
The content of the invention
The technical problem to be solved is to provide one kind and overcomes conventional sealing apparatus to seal
Effect is unstable, and airtight and watertight padding utilization rate is low, changes frequent, the big problem of maintenance workload
Automatically the sealing device of wear extent is compensated.
To solve above-mentioned technical problem, the present invention is realized as follows：Design is a kind of certainly
The sealing device of dynamic compensation wear extent, its by adjusting screw rod, sealed letter, indicating arm, pad,
Elastic fluid, pressing plate and airtight and watertight padding composition；Adjusting screw rod constitutes screw thread and coordinates company with sealed letter
Connect；Adjusting screw rod lower end is pressed against pad upper surface, and pad lower surface compresses elastic fluid；Refer to
Show that bar lower end is constituted with pressing plate upper surface to be fixedly connected, while indicating arm sequentially passes through elastic Jie
Through hole in the middle of matter, pad and adjusting screw rod, indicating arm upper end protrusion is arranged on adjusting screw rod
End is outside；Elastic fluid lower end clamping platen upper surface, pressing plate lower surface compresses airtight and watertight padding,
Airtight and watertight padding is constituted to be brought into close contact and is connected with equipment surface.
Further, for the screw thread for ensureing to lock stability, the adjusting screw rod and sealed letter
It is self-locking thread engagement connection to be connected.
Further, thrust is adjusted for convenience, recovers the design decrement of elastic fluid,
The upper head of the adjusting screw rod is shaped as being engaged the structure of pivot bottom screw rod with staff
Shape.
Further, thrust is adjusted for convenience, recovers the design decrement of elastic fluid,
The upper head of the adjusting screw rod is shaped as polygon.
Further, thrust is adjusted for convenience, recovers the design decrement of elastic fluid,
The upper head of the adjusting screw rod is the one kind in knob, handle.
Further, in order to position firm and prevent elastic fluid overcompression, under the indicating arm
With diameter greater than upper diameter, its section is arranged in step in portion, and indicating arm lower height is L, L
Equal to from height during elastic fluid design maximum working load.
Further, there are salient position sign scale and alert flag, institute to ensure indicating arm
State height not less than elastic fluid in the minimum service load of design of the whole height of indicating arm,
The thickness of pad and the entire length sum of adjusting screw rod.
Further, use for convenience, the elastic fluid is spring.
Further, use for convenience, the indicating arm upper design has scale or warning
Labelling.
The positive effect of the present invention：In technical solution of the present invention, self-locking screw rod, band limit are employed
The innovation structure that position indicating arm and spring are engaged, realizes long-term lasting wear automatic-compensation
Mechanism and the hommization of maintenance work；Can intuitively be understood by the scale of indicating arm projection
The thrust change of spring.After pressing force of the spring reduces, screw rod is screwed can again recover spring
Thrust, breach the limited limitation of spring travel, considerably increase the compensation of sealing device
Stroke.So as to the utilization rate of airtight and watertight padding is significantly improved, the replacement cycle of airtight and watertight padding shows
Write and extend.The spacing design of indicating arm simultaneously can prevent spring overcompression again, and protection is played to spring
Effect, has ensured device sealing property steady in a long-term, is a kind of simple structure, using can
By, processing cost is low, maintenance workload is little, airtight and watertight padding replacement cycle length and utilization rate is high
New type sealing device.
