Abstract
The utility model relates to an inflating quick connector for vacuum. The inflating quick connector comprises a movable plug and a fixed plug seat, wherein the external wall of the movable plug and the internal wall of the fixed plug seat are connected so as to realize seal, a primary sealing ring is mounted in a sealing groove of the surface of an outside circle of the movable plug, and the movable plug can be in sealed connection with the fixed plug seat through the primary sealing ring. According to the inflating quick connector, the structure is simple, sealing rings can be replaced conveniently after the sealing rings are worn, and the effect that the quick connector is quick in connection and convenient and quick in replacement is achieved.
Description
Technical field
The utility model relates to a kind of vacuum inflating fast joint.
Background technique
Existing vacuum gas filling joint mostly is flange Connecting format, KF structural type, CF structural type, although part is more while adopting this structure sealability reliably to install, efficiency is not good enough; Existing another vacuum gas filling joint is that fast insertion type joint comprises movable plug and locking-type plug seat, this kind of vacuum gas filling jiont treatment efficiency high sealing is reliable, but because Sealing between movable plug and locking-type plug seat is the inside that is placed in locking-type plug seat end, therefore make to change Sealing very difficult, the replacing time is increased.
Model utility content
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of simple in structure, sealability is reliable, installation efficiency is high and change Sealing vacuum inflating fast joint easily.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of vacuum inflating fast joint, comprise movable plug and locking-type plug seat, the outer wall that described movable plug is slotting and the inwall of described locking-type plug seat are connected realizes sealing, primary seal circle is installed in the seal groove of the outer round surface of described movable plug, and described movable plug is realized with described locking-type plug seat and being tightly connected by described primary seal circle.
In described movable plug and described locking-type plug seat, be respectively equipped with movable end spring spool and fixed end spring spool, on the face that described movable end spring spool contacts with described movable plug, the second seal ring is installed, on the tactile face of described fixed end spring spool and described locking-type plug seated connection, the 3rd seal ring is installed.
Owing to adopting such scheme, patented product sealing adopts O type rubber ring, expansion extruding by rubber ring realizes sealing, this device one has 3 sealing surfaces, it is movable plug outer round surface that one of them seal ring is arranged on, this is primary seal circle, adopts radial seal, realizes the effect that joint outside and joint internal insulation reach sealing when joint inserts; Another two seal rings lay respectively at the seal ring on the movable spool end of two springs, when movable plug is extracted, outside the movable spool of spring is first under spring force effect, eject, the seal ring being positioned on its end face is faced the wall and meditated contact by end face seal in tip side, like this after extracting movable plug with movable plug (with fixed base) pipeline that is connected is all sealed, realizes two way sealed.
In sum, seal ring owing to can often wearing and tearing in primary seal circle plug-in mounting process, is therefore arranged on primary seal circle in the cylindrical seal groove of movable plug, thereby after ring wear, can be convenient for changing, reach rapid pipe joint and connect fast and change effect easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the movable end spring spool sealing state figure of the utility model movable joint;
Fig. 3 is the fixed end spring spool sealing state figure of the utility model locking-type plug seat;
In accompanying drawing 1 to 3,1---movable plug, 2---locking-type plug seat, 11---primary seal circle, 12---movable end spring spool, 13---the second seal ring, 21---fixed end spring spool, 22---the 3rd seal ring.
Embodiment
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
Referring to figs. 1 through 3, a kind of vacuum inflating fast joint, comprise movable plug 1 and locking-type plug seat 2, primary seal circle 11 is installed in the seal groove of the outer round surface of described movable plug 1, and described movable plug 1 is realized being tightly connected of outer wall and described locking-type plug seat 2 inwalls by described primary seal circle 11.In described movable plug 1 and described locking-type plug seat 2, be respectively equipped with movable end spring spool 12 and fixed end spring spool 21, on the face that described movable end spring spool 12 contacts with described movable plug 1, the second seal ring 13 is installed, on the face that described fixed end spring spool 21 contacts with described locking-type plug seat 2, the 3rd seal ring 22 is installed.
During work, primary seal circle 11 adopts radial seal, realizes the effect that joint outside and joint internal insulation reach sealing when movable plug 1 inserts locking-type plug seat 2; When movable plug 1 is extracted, outside movable end spring spool 12 and fixed end spring spool 21 are first under spring force effect, eject, as shown in Figures 2 and 3, the second seal ring 13 being positioned on its end face contacts end face seal with the end-face wall of movable plug 1 and locking-type plug seat 2 respectively with the 3rd seal ring 22, like this after extracting movable plug with movable plug (with fixed base) pipeline that is connected is all sealed, realizes two way sealed.
