Abstract
This invention relates to high pressure container sealing device, which puts ring sealing ring racket on the ring surface on the end of the container cylinder and puts flat cover on the racket, wherein the cover top is located with anti-shearing ring enclosed by evenly distributed fan ring pads and two sides ring pads. The cylinder inner wall is located with ring groove with relative thickness to the anti-shearing ring. The cylinder is opened with holes connected to the screw holes of the anti-shearing ring. The screw bar passes screw holes of the anti-shearing ring.
Description
Technical field
The present invention relates to the seal arrangement of high-pressure bottle, specifically be applicable to the seal arrangement that can bear the internal high pressure liquid medium of high-pressure bottle.
Background technique
High-pressure bottle seal arrangement commonly used adopts metallic shim mostly, with the initial pre-tightening seal of the pretightening force generation of bolt; Under the normal working of container, bear the living axial force of cutting down output in the container by bolt, rely on the fitting surface of pad and cylindrical shell end, flat cover to guarantee the sealing of container.Wood closure does not have stressed kingbolt, and sealing is reliable, but complex structure, the matching requirements height.Though improved wood closure has been simplified some parts, removed the pretension bolt of metallic shim, also used seal with O ring, do not reduce the manufacture difficulty and the installation difficulty of wood closure in essence.Such as, the metallic shim that requirement on machining accuracy is very high cooperates still and exists; During the container proper functioning, stressed bigger turnbuckle still exists, and the material of turnbuckle and requirement on machining accuracy are all higher.
Summary of the invention
It is low to the purpose of this invention is to provide a kind of matching requirements, sealing device for high-pressure container simple in structure.
Sealing device for high-pressure container of the present invention, it is characterized in that on the ring-shaped bearing plane of high-pressure bottle cylindrical shell end, placing the O-ring seal carriage, above the O-ring seal carriage, place flat cover, circumferential and last plane along the O-ring seal carriage has groove, be respectively equipped with in the groove with barrel and form first O-ring seals of sealing and form second O-ring seals that seals with flat cover, circumferentially have two grooves at least along flat cover, be respectively equipped with the 3rd O-ring seals that forms sealing with barrel in the groove, above flat cover, be equipped with anti-shear ring, anti-shear ring is to be surrounded alternately by the fan-shaped ring plate circular ring plate of dividing equally parallel with bi-side, radially be provided with screw at every fan-shaped ring plate and circular ring plate, be provided with and the corresponding circular groove that supplies anti-shear ring to insert of the thickness of anti-shear ring at cylinder inboard wall, have on the cylindrical shell with anti-shear ring on the hole that connects of screw, screw rod passes through stubborn the connecing of screw on this hole and the anti-shear ring, and the position block of screw rod is bearing in the outer wall of high-pressure bottle cylindrical shell.
The present invention is the seal arrangement that does not have stressed bolt fully, and it has thoroughly broken away from metallic shim and cushion block, and is simple in structure, utilizes dismounting that screw rod makes anti-shear ring in the cylindrical shell peripheral operation, and easy installation and removal can be guaranteed the reliability that seals by dimensional chain.Because machining accuracy and surface roughness that seal with O ring requires generally reduce by 2 grades than the metallic shim sealing, therefore, all adopt seal with O ring, have reduced the difficulty of processing and the installation difficulty of total, make the convenient to disassembly of pressurized container flat cover.
Description of drawings

Fig. 2 is a kind of concrete anti-shear ring schematic representation.
Embodiment
With reference to Fig. 1, sealing device for high-pressure container of the present invention, on the ring-shaped bearing plane 1 of high-pressure bottle cylindrical shell end, place O-ring seal carriage 2, above O-ring seal carriage 2, place flat cover 3, circumferential and last plane along O-ring seal carriage 2 has groove, be respectively equipped with in the groove with barrel and form first O-ring seals 7 of sealing and form second O-ring seals 8 that seals with flat cover 3, circumferentially have two grooves at least along flat cover 3, be respectively equipped with the 3rd O-ring seals 9 that forms sealing with barrel in the groove, above flat cover 3, be equipped with anti-shear ring 11, flat cover 3 suffered axial forces are born by the anti-shear ring above it 11, and pass to the cylindrical shell end, anti-shear ring 11 is to be surrounded alternately by the fan-shaped ring plate 13 of the dividing equally circular ring plate 14 parallel with bi-side, radially be provided with screw 10 at every fan-shaped ring plate 13 and circular ring plate 14, general anti-shear ring 11 is divided into 4～8, and as shown in Figure 2, anti-shear ring is divided into 6.Be provided with and the corresponding circular groove 12 that supplies anti-shear ring 11 to insert of the thickness of anti-shear ring 11 at cylinder inboard wall, have on the cylindrical shell with anti-shear ring on the hole 6 that connects of screw 10, screw rod 5 passes through screw 10 stubborn the connecing on this hole 6 and the anti-shear ring, and the position block 4 of screw rod 5 is bearing in the outer wall of high-pressure bottle cylindrical shell.The operating end of screw rod 5 is installed in the outside, cylindrical shell end, and the installation and removal of operation anti-shear ring promptly utilize screw rod that anti-shear ring is moved to the working position and shifted removed position onto.For ease of anti-shear ring is in place, the surface of contact of the upper surface of anti-shear ring and cylinder inboard wall circular groove 12 has the tapering that is meshed.In the using process of pressurized container, the radial seal of O shape circle, pre-sealed by flat cover deadweight assurance, along with the rising radial seal effect enhancing of pressure; The axial seal of second, third O shape circle, also effect strengthens along with the rising of pressing in the container.
