Abstract
The utility model discloses an overpressure prevention safety device of tanks. The safety device comprises a ceiling, a brace, a bolt, a gland, a gasket, an inner pad, a barrel body, a diaphragm, a protective net and a chain, wherein the gland positioned on the barrel body is matched with a front edge of an end face and assembled with the inner pad, the diaphragm and the gasket sequentially, and after being matched, the barrel body and the gland are sealed and connected by a bolt; the upper part of the gland is provided with the conical ceiling supported by the brace; and the vertical projection area of the ceiling is larger than the area of the gland. To stop broken diaphragms from falling into the tank, the diaphragm of an inner cavity of the barrel body is provided with the protective net at the lower part. As the ceiling can shield the diaphragm, rain and dust can be prevented from falling onto the diaphragm. Besides, when the diaphragm is blasted, the safety device can also stop broken pieces from bursting outwards and avoid accidents of hurting people. Usually, under the shielding action of the ceiling, the diaphragm is not easy to be touched and broken by accident. The safety device is simple and reasonable in structure, and suitable for matching with tanks of various specifications.
Description
Technical field
The utility model relates to the safety installations of a kind of supporting cabin cabinet, and specifically, the utility model relates to a kind of cabin cabinet superpressure preventing safety installations.
Background technique
In order to prevent that the pressurized container superpressure from having an accident, on pressurized container, dispose corresponding superpressure preventing safety installations usually.Prior art products is vertical structure; the middle part is provided with the easy rupture of membranes sheet of making by design rated pressure value up; when voltage rise in the container during to the rated pressure value, the superpressure preventing safety installations forms pressure release by the diaphragm explosion, and supporting pressurized container is effectively protected.Prior art is simple in structure, the exposed nothing of diaphragm retrains, pressure release is quick, can play the effect of superpressure preventing.The airtight cabin cabinet of large ship in fact also is a kind of pressurized container, and volume is big especially, and the superpressure preventing safety installations specification that is disposed is corresponding also very big.Because prior art products is a kind of no barrier structure, in case large-sized diaphragm generation explosion then danger close, the broken diaphragm that flies to collapse the away possibility of hurting sb.'s feelings.In addition, prior art products is supporting cashier's office in a shop in the cabin also to exist a structural imperfection, and promptly open-air the installation easily forms rainwater and dust accumulation on the diaphragm, causes the superpressure preventing safety installations malfunctioning and have an accident.
The model utility content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of cabin cabinet superpressure preventing safety installations with safeguard structure.This apparatus structure is simple, Safety performance good, and anti-rainwater, dust protection.
The utility model is achieved through the following technical solutions technical goal.
Cabin cabinet superpressure preventing safety installations, it comprises ceiling, pillar, bolt, gland, pad, interior pad, cylindrical shell, diaphragm, protective net and chain.Described gland is a flange-like, and the gland that is positioned on the cylindrical shell matches with the end face seam, and the seam junction is equipped with interior pad, diaphragm and the pad that matches from bottom to top successively, and cylindrical shell and gland large end face are provided with through hole and are tightly connected through bolt.Described chain two ends connect the flange edge of gland and cylindrical shell respectively.Its improvements are: described gland top is provided with the ceiling by the vertically-arranged pillar supporting.Described cylinder lumen is positioned at the diaphragm bottom and is provided with one deck protective net.
Ceiling in the said structure is conical, and the circular cone top is positioned at top, and ceiling vertical projection area is greater than 10%～30% of gland area.
The utility model compared with prior art has following good effect:
1, increases simple, the easily manufacturing of ceiling structure.Ceiling except anti-rainwater, dustproof, more important is to stop the diaphragm explosion to fly out to hurt sb.'s feelings, so Security is good.
2, cylindrical shell built-in protecting net effectively stops broken diaphragm to fall in the cabinet of cabin, reduces checkout time.
3, under the blocking of ceiling, can effectively avoid mistake to break the diaphragm accident.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Cabin cabinet superpressure preventing safety installations shown in the accompanying drawing 1, it comprises ceiling 1, pillar 2, bolt 3, gland 4, pad 5, interior pad 6, cylindrical shell 7, diaphragm 8, protective net 9 and chain 10.Described gland 4 is a flange-like, the gland 4 that is positioned on the cylindrical shell 7 matches with the end face seam, the seam junction is equipped with interior pad 6, diaphragm 8 and the pad 5 that matches from bottom to top successively, and the large end face of cylindrical shell 7 and gland 4 is provided with the through hole construction bolt 3 that matches and is tightly connected.Chain 10 two ends connect the flange edge of gland 4 and cylindrical shell 7 respectively.The utility model is provided with the conical ceiling 1 by 2 supportings of vertically-arranged pillar on gland 4 tops, its circular cone top is positioned at top, and ceiling 1 vertical projection area is greater than 10%～30% of gland 4 areas.In order to stop broken diaphragm 8 to fall in the cabinet of cabin, be positioned at diaphragm 8 bottoms at cylindrical shell 7 inner chambers and be provided with one deck protective net 9.Present embodiment is installed in cabin portion cashier's office in a shop, its cylindrical shell 7 internal diameter Φ 200mm, and gland 4 external diameters are Φ 320mm, belong to a kind of cabin cabinet superpressure preventing safety installations of big specification, by pillar 2 supporting ceilings 1,1 end of ceiling circular diameter is Φ 380mm to this device on gland 4.The vertical projection area of ceiling 1 enough can avoid rainwater and dust to drop down onto on the diaphragm 8 greater than the area 29% of gland 4 in this structure, in case diaphragm 8 also can stop fragment to collapse when explosion takes place, avoids taking place casualty accident outward.Under the blocking of ceiling 1, diaphragm 8 also is difficult for being bumped brokenly by mistake in daily.
