Abstract
The utility model relates to an X-shaped hollow sealing strip, and belongs to the technical field of mechanical sealing device manufacture. The X-shaped hollow sealing strip is mainly characterized in that the cross section of a rectangular sealing strip adopts an X-shaped structure; a hollow hole is formed in the rectangular sealing strip. The X-shaped hollow sealing strip has the advantages that the structure is simple; the use is convenient; as the center of the sealing strip adopts a hollow structure, the material consumption is low, the weight is light, and the manufacturing cost is low; the service life is long; the sealing and tightening force is low; the possibility of deformation is low; the X-shaped hollow sealing strip can recover the original shape after deformation; the creep deformation-resistant and anti-loose performances during use are very high; liquid or gas can be sealed and conveyed safely after the X-shaped hollow sealing strip is used in various machinery.
Description
One, technical field
The utility model relates to the Stamping Steel Ribbon using in a kind of machinery, and specifically a kind of X-type hollow seal bar, belongs to mechanical seal device manufacturing technology field.
Two, background technique
In heavy mechanical equipment, railway locomotive, transformer, automobile etc. have the equipment manufacturing technology field of liquid or gas conveying, in order to make mechanical internal cavity sealing effect better, prevent that liquid or gas are to external leakage, usually between mechanical fitting axially docks with mechanical fitting, pad has different Stamping Steel Ribbon or seal ring, can make mechanical connecting part place reach internal cavity sealing, realize the sealing of liquid or gas and conveying.For example, during to petroleum pipeline and engine assembly, all need to seal docking with Stamping Steel Ribbon or seal ring, prevent that joint poor sealing from causing gas leak of the oil leakage.The Stamping Steel Ribbon mechanically using now adopts homogenous material mostly, and the side's of being bodily form or circle shape, as rubber weather strip, rubber seal, metal o-ring, spring sealed circle etc.Sealing material in rubber weather strip is easy to distortion after being in use squeezed, and cannot get back to shape in the past after distortion, elasticity variation, but also will locate.When the accessory that particularly interface is plane seals, with existing Stamping Steel Ribbon, the most easily make Stamping Steel Ribbon deformed damaged and come off, thereby causing between mechanical fitting poorly sealed.Existing Stamping Steel Ribbon mostly is solid construction, and materials are many, and weight is large, and manufacture cost is high.
Three, model utility content
The purpose of this utility model is that materials are many in order to solve the existing Stamping Steel Ribbon side's of being bodily form or circle shape solid construction, and weight is large, and manufacture cost is high, and easily distortion is difficult to after distortion be returned to shape in the past, thereby proposes a kind of new technological scheme.
For achieving the above object, the utility model solves prior art defect can adopt following technological scheme:
An X-type hollow seal bar, it is that the Stamping Steel Ribbon that is rectangle by cross section forms, and the four sides of rectangular seal bar is concave curvatures, and its cross section is X-shaped structure, in rectangular seal bar, is provided with hollow hole.
Concave curvatures in the four sides of rectangular seal bar in corresponding two sides is hyperbolic structure, the intracardiac hollow hole that is provided with in rectangular seal bar.
The advantage that the utility model compared with prior art had is: simple in structure, easy to use, sealing fastening force is little, Stamping Steel Ribbon is hollow-core construction, good springiness, easily location, good sealing effect, materials are less, lightweight, cheap for manufacturing cost, long service life, is not easy distortion, still can be returned to shape in the past after distortion, during use, creep resistant relaxation property is very good, on various mechanized equipments, can realize the security seal to liquid or gas.
Four, accompanying drawing explanation
Accompanying drawing 1 is a kind of example structure schematic diagram of the utility model;
Accompanying drawing 2 is that the A-A of the utility model accompanying drawing 1 is to cross-sectional schematic;
Accompanying drawing 3 is perspective view of the utility model accompanying drawing 1.
In accompanying drawing: 1, Stamping Steel Ribbon; 2, hollow hole; 3, concave curvatures.
Five, embodiment
Now with specific embodiment, the utility model is described in further details by reference to the accompanying drawings:
An X-type hollow seal bar, it is to be that square Stamping Steel Ribbon 1 forms by cross section, the concave curvatures 3 in the four sides of quad seal bar 1 in corresponding two sides is hyperbolic structure, makes the cross section of quad seal bar 1 be X-shaped, the intracardiac hollow hole 2 that is provided with in quad seal bar 1.
The utility model in use can make the inside and outside bulging of core on every one side by extruding, after being expressed to a certain degree, the sectional shape of Stamping Steel Ribbon 1 is square, after decompression, can reply original shape, Stamping Steel Ribbon 1 also can be made rubber seal, according to the needs of mechanical seal, can make various shapes, can be widely used in machinery manufacture.
Claims (2)
1.X type hollow seal bar, it is that the Stamping Steel Ribbon that is rectangle by cross section forms, and it is characterized in that: the four sides of rectangular seal bar (1) is concave curvatures (3), and its cross section is X-shaped structure, is provided with hollow hole (2) in rectangular seal bar (1).
2. a kind of X-type hollow seal bar according to claim 1, it is characterized in that: the concave curvatures (3) in the four sides of rectangular seal bar (1) in corresponding two sides is hyperbolic structure the intracardiac hollow hole (2) that is provided with in rectangular seal bar (1).
