Abstract
The utility model relates to a top sealed end radial support for a vertical Dewar bottle liner and belongs to a top support component of a Dewar bottle. An integral top sealed end radial support which is formed by connecting a joint and a transition connecting member by a supporting strip is connected with a connecting edge having a neck tube and an outer casing. Because the radial support is additionally arranged on the Dewar bottle, the stressed state of the neck tube can be improved and the neck tube does not bear radial force to generate curved neck, and bending stress is also eliminated. The safety accidents resulting from the neck tube can not occur even when the Dewar bottle which is filled with liquid is overturned, so the safe reliability of the Dewar bottle can be enhanced.
Description
The utility model relates to a kind of storage, transportation and uses the vertical cryogenic liquid vessel of middle-size and small-size high vacuum multiple layer heat insulation of liquid gas (liquid oxygen, liquid nitrogen, liquid argon), the main support parts of Dewar vessel, the upper cover radial support of vertical Dewar vessel inner bag.
Existing vertical Dewar vessel inner bag supports, and adopts the upper support that neck tube fuses inner bag and shell and the lower seal head radial support of inner bag outer casing bottom to support, and inner bag is hung be fixed in the middle of the shell.Neck tube not only will bear pressure and inner bag weight, also will bear added force of inertia and consequent moment of flexure and flexural stress that it produces in transportation, loading and unloading.Consider from safety, intensity angle, should reduce the moment of flexure of neck tube, the composite bending modulus of increase neck tube, neck tube is designed to length weak point, thick, the thickness of pipe wall of caliber, but the leakage heat that directly causes the neck tube solid conduction to produce again like this rises significantly.Be inversely proportional to because of leaking the hot size and the length of neck tube, be directly proportional with sectional area, for reach Dewar vessel the day relative evaporation in the standard applicable scope, the neck tube design must in intensity and be leaked to weigh between heat and be determined, because of the overturning of contingency Dewar vessel, limited by its neck tube bending resistance, also can cause interior leakage even security incident.
The purpose of this utility model is to provide a kind of upper cover radial support of vertical Dewar vessel inner bag, improves the stress of neck tube greatly, and improves safety, the reliability of Dewar vessel.
The utility model is to realize like this.The upper cover radial support of vertical Dewar vessel inner bag, the radial support of end socket on the whole that joint and transition piece is connected into by stay, and be connected with shell with the edge that connects of band neck tube.
Fig. 1. user mode figure of the present utility model.
Fig. 2. the structural representation that the upper cover radial support supports.
Fig. 3. the upper cover radial support supports the cooperation place enlarged view.
Fig. 4. the upper cover radial support supports the alternative plan structural representation.
Fig. 5. the partial enlarged drawing of joint.
Fig. 6. the partial enlarged drawing of joint.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Stay (10) is by the stainless steel steel wire, or stainless steel bar, pipe, plate, bar, carrying material are made.
Joint (9), (9) ' be circle or polygonal, point ring, the circular arc ring of protrusion arranged on the inner hole wall.
Transition piece (8), (8) ' be ring, uniform, at interval, discontinuous curved plate bar.
Upper cover radial support (3) by uniform 3 bracing bars (10) (or by the 4-6 root, Stainless Steel Wire making or stainless steel bar, pipe, band, lath are made) on welding or screw thread are fixed on joint (9), (9) respectively ' and transition piece (8), (8) ', connect formation in aggregates, and with shell (6) shell ring internal diameter assembly welding.
Connecing edge (2) is tubular shape, and there are ring groove and neck tube (1) drive fit in the upper-end surface, and inner bag (4) stressed joint of lower end and band wrapping layer (5) connects edge (2) external diameter and joint (9), (9) ' the endoporus cooperation contacts for line.
Support (3) by the upper cover radial support and support (7) with the lower seal head radial support bear the radial component that inner bag overall radial inertial force that Dewar vessel produced and gravity produce in transportation, loading and unloading, or bear Dewar vessel tilt to crouch put, gravity when overturning or the component of gravity generation.Like this, neck tube (1) only bears the axial added force of inertia that produces in pulling force or pressure, inner bag gross weight and the transportation thereof, the moment of flexure, the no flexural stress that produce of bearing radial force no longer, improved the stress of neck tube (1) greatly, it can be determined by pulling force and Dewar vessel Structural Design Requirement that the axial added force of inertia that produces in inner bag gross weight and the transportation thereof produces.Even the Dewar vessel overturning of full of liquid simultaneously, neck tube (1) can not be subjected to curved yet and damage, the security incident that causes because of neck tube (1) reason can not take place, improved Dewar vessel safety, reliability.
The utility model compared with prior art; Because having increased by one by stay, joint, transition piece group The upper cover radial support that becomes supports, and the stress of neck tube is improved, neck tube only bear internal pressure, The axial added force of inertia that produces in inner bag gross weight and the transportation thereof, no longer the moment of flexure that produces of bearing radial force, No bending stress. And the stay of inner bag upper cover radial support is elongated, contact with the line that is connected to of inner bag, because of Set up support that inner bag upper cover radial support increases and leak that thermoae it is limited, but improved Dewar bottle safety, Reliability.
