Abstract

The invention discloses a big aperture blanking cap, which comprises a plug, a bolt, a nut, a gasket and an extrusion structure, and is characterized in that the bolt is sleeved in the center of the plug, the extrusion structure is arranged on one end of the bolt, and the gasket and the nut are arranged on the other end of the bolt. The nut and the bolt can relatively move by rotating the nut, thereby enabling the extrusion structure to move toward the direction of the nut, extruding the plug to enable the plug to expand, enabling an opening of a container to be airtight, and keeping pressure and weight.

Description

A kind of heavy caliber blanking cover
Technical field
The present invention relates to a kind of heavy caliber blanking cover, its predominant use ensures the installation quality in the air tightness test in the key hole without safety installations and the safety in using process.
Background technique
In the gastight containers such as manufacture and experiment fuel tank, usually need to do hermeticity experiment, generally, have tight lid usually to copy a set of similar frock according to prototype, utilize the mounting points of former blanking cover to carry out compact siro spinning technology, then do air tightness test.But due to large-scale fuel tank, the technique process division of labor is clear and definite, for needing without mounting points and will ensureing blocking or the blocking of vessel surface quality, installation question exists always.
Summary of the invention
In order to solve without mounting points and the installation question of the blanking cover/blocking of vessel surface quality will be ensured, the invention provides a kind of heavy caliber blanking cover, not only can ensure gas-tight qualities but also can safety protection be played.
The present invention adopts following technical proposals to realize.A kind of heavy caliber blanking cover, comprises blocking, bolt, nut, packing ring, extrusion structure, it is characterized in that: at blocking center suit bolt, one end of bolt arranges extrusion structure, and the other end of bolt installs packing ring and nut.Tightening nut can make nuts and bolt relative movement, thus makes extrusion structure to the motion of nut direction, thus extruding blocking, make blocking bulging, thus it is airtight that vessel port is obtained, pressurize guarantor measures.Described blocking is elaxtic seal.
Preferably, described extrusion structure is the cone structure with bolt one.Further, also at the additional hoop that is installed of blocking, to limit the relative position being jammed in bolt, it can be made not to be separated, wire or rope also can be used as safety fuse cutout jointing clip and bolt.
As another kind of preferred version, described extrusion structure is mounted in the stiffener plate of bolt one end, can arrange rubber on the surface of stiffener plate, makes it contact softer with blocking.Described blocking is formed by rubber with for the shape support plate of fixing rubber, also can arrange seal ring and spring washer between nut and blocking.
Heavy caliber blocking cover structure of the present invention is simple, easy to operate, solves and solves without mounting points and will ensure the design and installation problem that the blanking cover of vessel surface quality blocks, improve frock manufacture, the efficiency of test; Solve the potential safety hazard that blanking cover in using process flies out, improve the tightness of blanking cover.Therefore practicability is better, is easy to apply, has larger development and application values in professional domain.

Embodiment
Embodiment 1
As depicted in figs. 1 and 2, this heavy caliber blanking cover, comprise blocking 105, bolt 102, nut 104, packing ring 103, extrusion structure, described extrusion structure is the cone structure 207 with bolt 102 one, at blocking 105 center suit bolt 102, one end of bolt 102 arranges cone structure 207, and the other end of bolt 102 installs packing ring 103 and nut 104, also can block additional be installed hoop 106 time blocking 105 be fixed together with bolt 102.Tightening nut 104 can make cone structure 207 extrude blocking 105, make blocking 105 bulging, thus it is airtight that vessel port is obtained, and pressurize guarantor measures.Described blocking 105 is elaxtic seals, as rubber.Also in bolt 102 outer end perforate, and use safety fuse cutout 101 jointing clip 107, described safety fuse cutout 101 is wire or rope.In this embodiment, blocking 105 relies on friction can bear 30 ~ 40KPa pressure.
Embodiment 2
As described in fig. 3 and fig. 4, a kind of heavy caliber blanking cover, comprise by rubber 208 and the blocking 205 that forms for the shape support plate 207 of fixing rubber 208, also comprise a bolt 202 be sleeved in blocking 205, one end mounting nuts 204 of bolt 202, packing ring, spring washer, seal ring 203, (nut 204, packing ring, spring washer, seal ring 203 are inwardly installed successively from outer end), the other end of bolt 202 installs stiffener plate 206, and rubber 201 is set on the surface of stiffener plate 206, make it contact softer with blocking 205.During rotary nut, stiffener plate 206 can be made to extrude the rubber 208 of blocking 205, make rubber 208 bulging and realize sealing.The blocking 205 of this embodiment relies on close positioning can bear general pressure.
