Description
Technical field
The utility model is related to a kind of mechanical seals, especially a kind of to be sealed from jam type packing.
Background technology
Packing seal is mainly used for the dynamic sealing of the process machine and equipment motion parts in machinery industry, for example centrifuges
The plunger or piston rod of pump, compressor, vacuum pump, blender, the rotating shaft sealing of reaction kettle and reciprocating pump, reciprocating compressor,
And do sealing between straight line, the valve rod of screw valve and fixed body;
And traditional packing seal usage time is short, needs timing manual maintenance, there are problems that security risk.It is existing to fill out
Material sealing is mostly pressed on using gland bolt in stuffing box, through use after a period of time, filler abrasion, between rotary shaft
Gap increases, leakage increase, just needs manually to tighten bolt at this time, increases pressing force.In order to ensure to produce, need repairing personnel
Timed maintenance, while also bring some potential safety problems.
Utility model content
Therefore, to overcome above-mentioned deficiency, the utility model provides a kind of reasonable design herein, simple in structure, easy to use,
The packing seal of service life length increases floating ring, compression ring and spring, by bullet by improving between stuffing box and filler
Spring force persistently to provide pressing force to filler, thus with external force tighten bolt without manually timing, by compress gland come to
Filler provides pressing force, avoids maintenance personnel in production scene tight fixed bolt, personal safety prestige caused by dielectric leakage
The side of body.In addition we increase broach behind the position of stuffing box filling material, this can slow down the leakage rate of medium, extend
The usage time of packing seal.
It is sealed the utility model is realized in this way construction is a kind of from jam type packing, it is described including stuffing box and gland
Stuffing box is connect by bolt with gland, and forms seal assembly, which is connected to cavity by stay bolt again;
Filler is additionally provided between the seal assembly and rotary shaft, compression ring is disposed between the filler and gland
And gland, another side compression compression ring are tightly attached in floating ring, floating ring side, which compresses filler again;
Spring is additionally provided between the floating ring and compression ring.
Preferably, the stuffing box front end is additionally provided with broach with rotary shaft contact position.
Preferably, it is provided with O-ring seal between the stuffing box and gland.
Preferably, it is provided with O-ring seal between the stuffing box and cavity.
The utility model has the advantages that:
The utility model is designed reasonably, it is simple in structure, it is easy to use, by changing to pervious packing seal structure
Into, floating ring, compression ring and spring are increased between stuffing box and filler, by spring force come persistently give filler provide compression
Power thus tightens bolt without manually timing with external force, provides pressing force to filler by compressing gland, avoids maintenance
In production scene tight fixed bolt, personal safety caused by dielectric leakage threatens personnel.In addition we load in stuffing box and expect
Position behind increase broach, this can slow down the leakage rate of medium, extend the usage time of packing seal;
By improving, the usage time of packing seal is extended, the labor intensity of maintenance personal is alleviated, has ensured scene
The life safety of personnel, while reduce the leak time of packing seal, reduce environmental pollution.
The utility model clever structure simultaneously, installation and removal are convenient, and convenient for maintenance from now on, easy to manufacture is at low cost,
Using effect is good, long lifespan, is suitble to promote the use of.

Specific embodiment
The utility model is described in detail below in conjunction with attached drawing 1, to the technical side in the utility model embodiment
Case is clearly and completely described, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than
Whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work
Under the premise of all other embodiments obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the utility model provide herein it is a kind of sealed from jam type packing, including stuffing box 4 and gland 2,
The stuffing box 4 is connect, and form seal assembly by bolt with gland 2, which is connected to chamber by stay bolt 5 again
Body 3;
Filler 9 is additionally provided between the seal assembly and rotary shaft 1, pressure is disposed between the filler 9 and gland 2
Gland 2, another side compression compression ring 7 are tightly attached in tight ring 7 and floating ring 6,6 side of floating ring, which compresses filler 9 again;
Spring 8 is additionally provided between the floating ring 6 and compression ring 7.
According to described in the utility model a kind of from jam type packing sealing, 4 front end of stuffing box and 1 contact position of rotary shaft
It is additionally provided with broach 10.
It is sealed according to one kind described in the utility model from jam type packing, O is provided between the stuffing box 4 and gland 2
Type sealing ring 11.
It is sealed according to one kind described in the utility model from jam type packing, O is provided between the stuffing box 4 and cavity 3
Type sealing ring 11.
The utility model specific implementation is as follows:
Before installation, filler 9 is first packed into the stuffing box 4 with comb structure, then compress filler 9 with compression ring 7, then by bullet
Spring 8 is packed into floating ring 6, holds out against compression ring 7 and filler 9, finally with 11 sealed stuffing box 4 of O-ring seal and gland 2, use is short
Bolt is by stuffing box 4 and 2 assembling parts of gland into a component(It is sealed from jam type packing);In use, by component with O-shaped close
Seal 11 is sealed in cavity 3, is packed into rotary shaft 1, is fixed in the cavity come sealing medium with stay bolt 5.With rotary shaft 1 with
The abrasion of filler 9 increases, and generates gap, but spring force persistently can apply pressure to filler 9, keep filler 9 and rotary shaft 1
It fits closely, thus increases the usage time of filler 9, a small amount of 11 structure of broach for leaking through on stuffing box 4 can subtract
The leakage of slow medium, environmental protection and personal safety.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or new using this practicality
Type.A variety of modifications of these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide range consistent with features of novelty.
