Description
Technical field
The utility model is related to reciprocating technique compressor accessory field, more particularly to a kind of novel reciprocating type technique compression
Secret seal ring.
Background technology
Domestic large reciprocating technique compressor is both referred to American Petroleum Institute's API618 standards design production, sealing ring
Filler gas amount of leakage is mainly made up of greatly two reasons：The design of stuffing-box spatial margin is too small, causes sealing ring group number too
Few, sealing effectiveness is bad；Seal ring structure design is unreasonable.
The content of the invention
To solve problems of the prior art, the utility model provides a kind of novel reciprocating type technique compressor seal
Ring, the sealing ring can play the dynamic off-load of radial direction ring, and the dynamic sealing action of tangential ring can be served as again, while thickness is only
It is only suitable with original a piece of sealing ring, so that more airtight and watertight padding group numbers can be installed under fixed stuffing box space,
Reach better seal effect.
The technical solution of the utility model is：
A kind of novel reciprocating type technique compressor seal ring, including sealing ring body, the sealing ring body are located at filler
In box, the sealing ring body includes tangential seal, and the tangential seal includes two in annular shape, the tangential seal
Individual structure is identical and mirror image is set the first radial seal valve and the second radial seal valve, the first radial seal valve and second
Radial seal lobed is into inner ring, and the inner ring both sides are tangentially provided with the first tangential sealing flap and the second tangential sealing flap, described the
One tangential sealing flap, the first radial seal valve, the second tangential sealing flap and the second radial seal valve are arranged in order to form annulus
Shape.
The sealing ring body also includes radial seal, and the radial seal is in annular shape, the radial seal
Be arranged in order and constituted by the first radial direction block, the second radial direction block, the 3rd radial direction block and the 4th radial direction block, the first radial direction block with
All structure is identical respectively with the 4th radial direction block for 3rd radial direction block and the second radial direction block, the first radial direction block and the first radial seal
Valve, the second radial direction block and the first tangential sealing flap, the 3rd radial direction block and the second radial seal valve and the 4th radial direction block and second
Tangential sealing flap is all laminated integrated structure respectively.
Side along annulus outer ring is around being provided with stopper slot, the stopper slot provided with spring, and the sealing ring body is led to
Spring is crossed to fix tangential seal and radial seal and combine to be formed.
The radial seal is set towards cylinder direction, and the tangential seal is set towards crankshaft direction.
The utility model has the advantages that：Due to taking above-mentioned technical proposal, due to taking above-mentioned technical proposal,
The conventional technique compressor seal ring combining structure in the country is：Radial direction ring, tangential ring and block ring three are one group, this practicality
New described novel sealing ring is a piece of can to play the dynamic off-load of radial direction ring, and the dynamic sealing that tangential ring can be served as again is made
With；Because the material polytetrafluoroethylene (PTFE) of sealing ring is in the case of mesohigh, it may occur that the situation of cold flow deformation, so every is filled out
The thickness of material can not be too thin, this results in it is determined that stuffing box space under, what the group number of airtight and watertight padding was to determine, this practicality
The thickness of the new novel sealing ring is suitable only with the thickness of existing a piece of radial direction ring or tangential ring, so as to be filled out in fixed
More airtight and watertight padding group numbers can be installed under magazine space, better seal effect is reached, the leakage of process gas is reduced, it is to avoid
Because gas leakage causes the pollution of lubricating oil.This novel sealing ring can be used for the reciprocating of diameter of piston rod 30mm-300mm
Technique compressor.
