Abstract

The utility model is related to a kind of groove static seal wide for cylinder tube and fairlead, it by:Cylinder barrel, groove, sealing ring, fairlead are constituted.Cylindrical one week of fairlead is provided with rectangular recess, and built with sealing ring, sealing ring one end is circular arc to groove, and the other end is plane, and towards there is pressure simultaneously, cylinder barrel is together by a threaded connection circular arc with fairlead.The product structure is simple, reasonable in design, and a sealing ring is housed between cylinder tube and fairlead, it is that a part is constituted, and because sealing ring one end is arc, the other end is plane, when certain pressure is born, sealing ring will not be extruded, rupture, good sealing effect, extend the service life of sealing ring, it is easy for installation, low production cost, it is that groove wide is used to be particularly suitable for fairlead.

Description

A kind of groove static seal wide for cylinder tube and fairlead
Technical field
The utility model is related to a kind of groove static seal wide for cylinder tube and fairlead.
Background technology
At present, the sealing ring between existing cylinder tube and fairlead is an O-ring plus a back-up ring, and it is two Part split is constituted, and when certain pressure is born, O-ring is easily extruded, rupture, causes sealing to fail, and have impact on making for sealing ring With the life-span, two parts install inconvenient, and production cost is high.
The content of the invention
The purpose of this utility model is to overcome disadvantages mentioned above, there is provided a kind of groove wide for cylinder tube and fairlead Static seal, the sealing ring that it mainly solves between existing cylinder tube and fairlead is an O-ring plus a back-up ring, It is that two part splits are constituted, and when certain pressure is born, O-ring is easily extruded, rupture, causes sealing to fail, two part peaces The problems such as filling inconvenient, production cost is high.The purpose of this utility model is achieved in that a kind of cylinder tube that is used for guiding The groove static seal wide of set by:Cylinder barrel, groove, sealing ring, fairlead are constituted.It is recessed that cylindrical a week of fairlead is provided with rectangle Groove, built with sealing ring, sealing ring one end is circular arc to groove, and the other end is plane, circular arc towards having pressure simultaneously, cylinder barrel with Fairlead is together by a threaded connection.The product structure is simple, reasonable in design, and one is equipped between cylinder tube and fairlead Sealing ring, it is that a part is constituted, and because sealing ring one end is arc, the other end is plane, when certain pressure is born, sealing Circle will not be extruded, and rupture, and good sealing effect extends the service life of sealing ring, easy for installation, low production cost, especially It is that groove wide is used to be adapted to fairlead.
Brief description of the drawings:
Accompanying drawing 1 is a kind of structural representation for cylinder tube and the groove static seal wide of fairlead of the utility model Figure.
Accompanying drawing 2 is a kind of seal configuration for cylinder tube and the groove static seal wide of fairlead of the utility model Schematic diagram.
1-cylinder barrel, 2-groove, 3-sealing ring, 4-fairlead
Specific embodiment:Describe most preferred embodiment of the present utility model in detail below in conjunction with the accompanying drawings, one kind is used for oil cylinder The groove static seal wide of cylinder barrel and fairlead by:Cylinder barrel 1, groove 2, sealing ring 3, fairlead 4 are constituted.Fairlead 4 it is cylindrical Rectangular recess 2 is provided with one week, groove 2 is circular arc built with sealing ring 3, the one end of sealing ring 3, and the other end is plane, circular arc Towards having pressure simultaneously, cylinder barrel 1 is together by a threaded connection shape with fairlead 4.
