Abstract
The utility model discloses a sealing ring anti-disengaging sealing structure and a sealing ring groove thereof. One groove wall face of the sealing ring groove is provided with an annular boss which protrudes towards interior of the groove and extends in the circumferential direction of a main sealing ring groove, the boss is provided with an annular joint part which is used for being tangent to the sealing ring to prevent the sealing ring from being disengaged, and the perpendicular distance between the joint part and the groove bottom surface of the sealing ring is larger than the radius of cross section of the sealing ring groove. Under the action of the annular boss, even if a flange in which the sealing ring groove is formed is arranged vertically or inversely, the phenomenon that the sealing ring is disengaged from the sealing ring groove does not occur.
Description
Technical field
The utility model relates to a kind of sealing configuration, is specifically related to a kind of seal ring Drop-proof sealing configuration and closure gasket groove thereof.
Background technique
Traditional cylindrical shell docking adopts flange to connect, for the sealing effect between two flanges docking end faces that guarantee to dock cylindrical shell, prevent gas leak phenomenon, the general O of employing RunddichtringO seals between two flange docking end faces, namely offer a U-shaped closure gasket groove on the end face of the flange of flange docking therein, then seal ring is embedded in closure gasket groove, when two flange extruding, seal ring generation extrusion-deformation, and then reaching sealing effect, that this sealing configuration has advantages of is simple in structure, sealing is strong.But, this sealing configuration is the Shortcomings part also, if shell flange butt end area is larger, the diameter of seal ring is just excessive accordingly, sometimes more than can reaching 1500mm, like this when the fitting tight circle, if when running into the flange docking end face vertically-arranged that has closure gasket groove or being inverted the fitting tight circle, seal ring comes off from closure gasket groove problem easily occurs; In order thoroughly not allow it come off, traditional mode adopts in closure gasket groove or smears a large amount of sealers or seal gease on seal ring, and this has a strong impact on the sealing effect of cylindrical shell.
The model utility content
The purpose of this utility model is to provide a kind of closure gasket groove that can prevent that the major diameter seal ring from coming off from vertically-arranged or inverted end face of flange; The utility model also provides the seal ring Drop-proof sealing configuration that uses the sealing annular groove simultaneously.
Closure gasket groove of the present utility model adopts following technological scheme: a kind of closure gasket groove of seal ring Drop-proof sealing configuration, have on one of them trough wall surface of sealing annular groove to the annular boss that is convexly equipped with in groove, circumferentially extend along the primary seal annular groove, this boss has for, annular connecting part in order to prevent seal ring from coming off tangent with seal ring, and the cross section radius of the perpendicular distance of closure gasket groove groove bottom greater than seal ring arrived in this connecting part.
The outer circumferential face of described boss is cambered surface, described connecting part is the arc top of cambered surface, the part between connecting part and closure gasket groove notch edge of cambered surface extends to notch along place, and this cambered surface part and notch form secondary closure gasket groove along the Delta Region between the plane at place.
seal ring Drop-proof sealing configuration of the present utility model adopts following technological scheme: a kind of seal ring Drop-proof sealing configuration, the first flange and the second flange that comprise docking, offer the U-shaped primary seal annular groove that embeds for the O RunddichtringO on the flange docking end face of the first flange, have on one of them trough wall surface of described primary seal annular groove to being convexly equipped with in groove, along the circumferential annular boss that extends of primary seal annular groove, this boss has with seal ring tangent, in order to the annular connecting part that prevents that seal ring from coming off, the cross section radius of the perpendicular distance of closure gasket groove groove bottom greater than seal ring arrived in this connecting part.
The outer circumferential face of described boss is cambered surface, described connecting part is the arc top of cambered surface, the part between connecting part and closure gasket groove notch edge of cambered surface extends to notch along place, and this cambered surface part forms secondary closure gasket groove with the Delta Region that the flange of the second flange docks between end face.
Adopt the closure gasket groove of said structure, owing to convexing with the annular boss that circumferentially extends along closure gasket groove on an one trough wall surface in groove, another trough wall surface that is used for the primary seal annular groove that the connecting part tangent with seal ring can be relative with it on boss coordinates the crush seal circle, prevent the purpose of seal ring from coming off in the primary seal annular groove to reach, therefore, under the effect of annular boss, even offer flange vertically-arranged or the inversion of closure gasket groove, all seal ring comes off from closure gasket groove phenomenon can not occur.
Description of drawings
Fig. 1 is a kind of embodiment's of seal ring Drop-proof sealing configuration of the present utility model structural representation;
Fig. 2 is the view of Fig. 1 when seal ring is not installed;
Fig. 3 is the view after the utility model crush seal circle.
Embodiment
the embodiment of the utility model seal ring Drop-proof sealing configuration: as Figure 1-3, the first flange 1 and the second flange 4 that comprise mutual docking, offer primary seal annular groove 5 on the flange docking end face of the first flange 1, the interior setting-in of primary seal annular groove 5 is by O RunddichtringO 2, have on the inside groove wall of primary seal annular groove 5 to being convexly equipped with in groove, annular boss 3 along the circumferential extension of primary seal annular groove 5, boss 3 has the connecting part tangent with seal ring 2, this connecting part is to the cross section radius of the distance between the groove bottom of primary seal annular groove 5 greater than seal ring 2, be embedded into closure gasket groove 5 when interior when seal ring 2 like this, the connecting part of boss 3 can prevent that seal ring from coming off.
As further optimization, the outer circumferential face of this annular boss 3 is cambered surface, the arc top of this cambered surface is the connecting part of boss 3, and the part between the notch at connecting part and closure gasket groove 5 of this cambered surface edge extends to notch along place, namely extend to the flange docking end of the first flange 1, this cambered surface part coordinates and forms a secondary closure gasket groove with the flange docking end face of the second flange 4.
As shown in Figure 1, when seal ring 2 be embedded into primary seal annular groove 5 interior after,, seal ring 2 is squeezed in primary seal annular groove 5, thereby prevents that seal ring 2 from coming off in primary seal annular groove 5 with under the outer side wall of primary seal annular groove 5 coordinates at annular boss 3; As shown in Figure 3, when the first flange 1 and the second flange 4 fastening after, seal ring 2 extrusions, and when cylindrical shell uses, because punching in cylindrical shell has pressurized gas, seal ring 2 will be subject to pressurized gas by the inboard applied pressure of cylindrical shell, finally makes seal ring 2 push laterally again when clamp-oning primary seal annular groove 5 and be crowded with secondary closure gasket grooves, plays the effect of double-sealing.
In other embodiments, annular boss also can be arranged on the water jacket wall of primary seal annular groove.
The embodiment of closure gasket groove of the present utility model: as Figure 1-3, consistent with the structure of closure gasket groove in above-described embodiment, its content does not repeat them here.
