Abstract
A kind of compound duplex positive round grooved seal circle for sealing without groove flange face is provided, there is O RunddichtringO, the spacing metal frame of outer ring-like and the spacing metal frame of interior ring-type, described O RunddichtringO sectional shape is that duplex is just circular, described O RunddichtringO is placed between the spacing metal frame of outer ring-like and the spacing metal frame of interior ring-type, described outer ring-like spacing metal internal frame internal face is shaped with annular projection I, the spacing metal frame outer wall of described interior ring-type is shaped with annular projection II, described annular projection I and annular projection II are mounted to respectively from O RunddichtringO both sides in O RunddichtringO and both keep sustained height, the consistency of thickness of the spacing metal frame of described outer ring-like and the spacing metal frame of interior ring-type and all lower than the thickness of O RunddichtringO.Adopt the utility model to solve mechanical sealing flange face and need process spacing groove, cause the technical barrier that difficulty of processing is large, manufacture cost is high, sealing effect is undesirable.
Description
Technical field
The utility model belongs to the Sealing manufacturing technology field between mechanical fitting, is specifically related to a kind of compound duplex positive round grooved seal circle for sealing without groove flange face.
Background technique
In the equipment manufacturing technical field that medium and small machinery, railway locomotive, transformer, automobile, petroleum pipeline etc. have liquid or gas conveying, in order to make machine internal cavity sealing effect better, prevent liquid or gas to external leakage, usually between mechanical fitting axially docks with mechanical fitting, process groove, then homogenous material is adopted to seal, the processing precision direct influence of groove to sealing effect, as rubber seal, metal o-ring, spring sealed circle etc.During special employing " O " RunddichtringO, groove precision and moment deviation easily cause seal failure between flange and seal ring, and in order to reach sealing effect, the roughness requirements of usual sealing surface is very high, virtually add cost and sealing effect is not ideal enough, be therefore necessary to propose to improve.
Model utility content
The technical problem that the utility model solves: for the compound duplex positive round grooved seal circle sealed without groove flange face, solve mechanical sealing flange face and need process spacing groove, cause the technical barrier that difficulty of processing is large, manufacture cost is high, sealing effect is undesirable.
The technical solution adopted in the utility model: for the compound duplex positive round grooved seal circle sealed without groove flange face, there is O RunddichtringO, the spacing metal frame of outer ring-like and the spacing metal frame of interior ring-type, described O RunddichtringO sectional shape is that duplex is just circular, described O RunddichtringO is placed between the spacing metal frame of outer ring-like and the spacing metal frame of interior ring-type, described outer ring-like spacing metal internal frame internal face is shaped with annular projection I, the spacing metal frame outer wall of described interior ring-type is shaped with annular projection II, described annular projection I and annular projection II are mounted to respectively from O RunddichtringO both sides in O RunddichtringO and both keep sustained height, the consistency of thickness of the spacing metal frame of described outer ring-like and the spacing metal frame of interior ring-type and all lower than the thickness of O RunddichtringO.
Further, described annular projection I and annular projection II are mounted in O RunddichtringO respectively from central position, O RunddichtringO both sides.
Further, all in the form of sheets, its thickness is 1/5th of outer ring-like metal frame or interior ring-type metal frame thickness for described annular projection I and annular projection II.
Further, described O RunddichtringO be placed in the spacing metal frame of outer ring-like and the spacing metal frame neutral position of interior ring-type and O RunddichtringO pressurized time elastic strain reach optimal seal.
Further, described O RunddichtringO diameter dimension 20%-30% larger than the thickness size of the spacing metal frame of outer ring-like or the spacing metal frame of interior ring-type.
The utility model advantage compared with prior art:
1, sealing flange face need not process spacing groove, reduces manufacturing procedure, reduces cost of production;
2, the inside and outside both sides of O RunddichtringO are equipped with the spacing metal frame of mutually level inside and outside ring-type, and the connection between sealing surface belongs to hard connection, and O RunddichtringO can not produce displacement, it is damaged to be out of shape;
3, O seal ring and inside and outside ring-type metal frame are compound molding, and difficult drop-off is out of shape;
4, structure is simple, easy to use, and sealing fastening force is even, seal ring is gum structure, and good springiness, easily locates, good sealing effect, materials are less, cheap for manufacturing cost, long service life, be not easy distortion, still can be returned to shape in the past after distortion, during use, creep resistant relaxation property is very good, and various mechanized equipment can realize the security seal to liquid or gas;
5, the sectional shape of O RunddichtringO is that duplex is just circular, and is twice linear sealing during the flange face sealing of two ends, and Double-insurance sealing effect is very excellent.

Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the I place enlarged view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing 1-3, a kind of embodiment of the present utility model is described.
For the compound duplex positive round grooved seal circle sealed without groove flange face, there is O RunddichtringO 1, the spacing metal frame of outer ring-like 2 and the spacing metal frame 3 of interior ring-type, described O RunddichtringO 1 sectional shape is that positive circular described O RunddichtringO 1 is placed between the spacing metal frame of outer ring-like 2 and the spacing metal frame 3 of interior ring-type, specifically, described O RunddichtringO 1 be placed in the spacing metal frame of outer ring-like 2 and interior ring-type spacing metal frame 3 neutral position and O RunddichtringO 1 pressurized time elastic strain the gap-fill between three is full.Described outer ring-like spacing metal internal frame 2 internal face is shaped with annular projection I 4, described interior ring-type spacing metal frame 3 outer wall is shaped with annular projection II 5, all in the form of sheets, its thickness is 1/5th of outer ring-like metal frame 2 or interior ring-type metal frame 3 thickness for described annular projection I 4 and annular projection II 5.Described annular projection I 4 and annular projection II 5 are mounted to respectively from O RunddichtringO 1 both sides in O RunddichtringO 1 and both keep sustained height, one of preferential, annular projection I 4 and annular projection II 5 are mounted in O RunddichtringO 1 respectively from central position, O RunddichtringO 1 both sides.The consistency of thickness of the spacing metal frame of described outer ring-like 2 and the spacing metal frame 3 of interior ring-type and all lower than the thickness of O RunddichtringO 1.Specifically, described O RunddichtringO 1 diameter dimension is than the thickness size large 20 ~ 30% of the spacing metal frame of outer ring-like 2 or the spacing metal frame of interior ring-type 3.
