Specific embodiment
To make the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to the present invention's
Specific embodiment is described in further detail.
As shown in Figures 1 to 6, connect an embodiment of the present invention provides a kind of for annular emission cylinder without flange pressure bearing and seal
Binding structure, including pedestal 2, sealing ring 3, spacing ring 4 and retainer ring；
It is tightly connected object launching tube 1 to refer mainly to need the nozzle section sealed, one is set on 1 nozzle section inner wall of launching tube
Highly it is the annular groove of b.Pedestal 2 refers to the part for being used for sealing or lid, 2 inner mold face of pedestal are designed according to requirement,
Outer profile design is mainly its gabarit diameter c, and pedestal 2 coordinates with sealing ring 3 equipped with an inclined-plane, avoids limiting equipped with a step
Position ring 4, the thickness of pedestal 2 is designed to ensure that be installed in place after do not interfere with retainer ring 5；Sealing ring 3 is made of hard material,
Ensure that it ensures there can also be certain bearing capacity while sealing, in the present embodiment, using metallic copper or using polytetrafluoro
Vinyl material is made；Spacing ring 4 is four sections be divided by a domain, is easily installed, and each section is designed with a screw hole
For being connected fixation with launching tube 1, four sections are embedded in the annular groove of 1 inner wall of launching tube, when pedestal 2 and the installation of sealing ring 3 are solid
Periodically, spacing ring 4 blocks sealing ring 3 and carries out /V；Retainer ring 5 is a full circle ring, mounted on 1 outside of launching tube, gabarit
Consistent with 1 gabarit of launching tube, uniformly distributed bolt hole, is bolted with pedestal 2 thereon, when bolt is tightened, pedestal 2 have cylinder to
The trend of outer movement, so as to compression seal ring 3, continued compression sealing ring 3, sealing ring 3, which is limited ring 4, to be stopped, sealing ring 3 and hair
The contact of 1 inner wall of shooting cylinder ensures the sealing of sealing ring 3 and launching tube 1, and the contact with 2 inclined-plane of pedestal of sealing ring 3 ensure that sealing
The sealing of ring 3 and pedestal 2, so as to fulfill the sealing of launching tube 1.
Wherein, the 1 inner mold face diameter a of contour dimension (diameter) c ＜ launching tubes of pedestal 2.
