Description
Technical field
The utility model relates to joint, particularly a kind of pressed gas joint.
Background technique
The joint of pressure piping generally adopts flange and is similar to the connection of water pipe movable joint and so on.Relative to higher pressure, the sealing of both is all not too reliable.The former generally needs welding, and the latter seals to a sealing gasket in the middle of relying on, and is usually used in the low pressure occasions such as water pipe, not too applicable to pressed gas.
Summary of the invention
The purpose of this utility model is to design a kind of pressed gas joint, and for dismountable pressure piping joint, sealing reliability is high, and resistance to pressure is good.
For achieving the above object, the technical solution of the utility model is:
A kind of pressed gas joint, it comprises, first fittings body, it is female joint, and its side is the connection pipeline section of connecting pipeline, and opposite side is end-to-end joint part, this end-to-end joint part is ring body structurc, ring body end face circumferentially offers the through screw of some axis, and outside ring body, annular groove is established in port inner edge, establishes seal ring in it; Second fittings body, it is tool joint pin, and its side is end-to-end joint part, and opposite side is the connection pipeline section of connecting pipeline; Wherein, described end-to-end joint part side wall ring establishes sealed groove, and this second fittings body end-to-end joint part is stretched in the first fittings body end-to-end joint part ring body, by arranging O RunddichtringO in sealed groove and annular groove, makes two end-to-end joint parts keep sealing; Described end-to-end joint part root loop establishes boss, and with this be pressed against with the seal ring that arranges in the first fittings body annular groove outside; Described end-to-end joint part rear end projection ring body, ring body circumferentially offers the through screw of some axis, is bolted the first fittings body end-to-end joint part ring body and locks with this.
Further, the seal ring arranged in described first fittings body annular groove is combined seal ring, and it is combined by inner circle rubber ring cylindrical metal ring.
The beneficial effects of the utility model:
The utility model is by arranging multiple-sealed structure and locked with bolts between end-to-end joint part, comparatively existing structure is high to make SEALING FITTING reliability, and resistance to pressure is good.Owing to adopting combined sealing structure, the utility model joint can bear 0-32MPA pressure and not leak, and is applicable to all kinds of non-corrosive pressed gas, gas temperature-40----120 degree Celsius.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of the utility model embodiment.
Fig. 2 is the decomposing schematic representation of the utility model embodiment.
Embodiment
See Fig. 1, Fig. 2, a kind of pressed gas joint of the present utility model, it comprises, the first fittings body 1, and it is female joint, its side is the connection pipeline section 11 of connecting pipeline, opposite side is end-to-end joint part 12, and this end-to-end joint part 12 is ring body structurc, and ring body end face circumferentially offers the through screw of some axis 121, outside ring body, annular groove 122 is established in port inner edge, establishes seal ring 3 in it; Second fittings body 2, it is tool joint pin, and its side is the connection pipeline section 21 of connecting pipeline, and opposite side is end-to-end joint part 22; Wherein, described end-to-end joint part 22 side wall ring establishes sealed groove 221, this the second fittings body 2 end-to-end joint part 22 is stretched in the first fittings body 1 end-to-end joint part 12 ring body, by arranging O RunddichtringO 4 in sealed groove 221 and annular groove 122, makes two end-to-end joint parts 12,22 keep sealing; Described end-to-end joint part 22 root loop establishes boss 23, and with this be pressed against with the seal ring 3 that arranges in the first fittings body 1 annular groove 122 outside; Described end-to-end joint part 22 rear end projection ring body 222, ring body circumferentially offers the through screw of some axis 223, connects the first fittings body 1 end-to-end joint part 22 ring body 222 and lock with this by bolt 5.
Further, the seal ring 3 arranged in described first fittings body 1 annular groove 122 is combined seal ring, and it is combined by inner circle rubber ring cylindrical metal ring.
The utility model is by arranging multiple-sealed structure and locked with bolts between end-to-end joint part, comparatively existing structure is high to make SEALING FITTING reliability, and resistance to pressure is good.
