Abstract
The utility model relates to a safety device for a vacuum storage tank housing, which can ensure the safety of a vacuum storage tank. The periphery of a circular sealing seat is connected with the top of the vacuum storage tank; an upper port is sealed and connected with a circular sealing plate through a vacuum sealing ring; the inside of the upper port is positioned in a vacuum state; a protective jacket is sleeved above the circular sealing plate; and the lower end of the protective jacket is connected with the top of the vacuum storage tank. The utility model has the advantages as follows: firstly, the inside and the outside of the safety device of the vacuum storage tank housing press a sealing cover by atmospheric pressure, so that the utility model not only is simple and practical, but also can be opened emergently to exhaust when the inside pressure exceeds the atmospheric pressure and is applied by the gravity of a top cover so as to ensure the safety of an inner vessel and an outer vessel; and secondly, ventilating ports are formed on the periphery of a protective housing of the vacuum storage tank housing, and the top of the vacuum storage tank housing can be used for avoiding the drench and the solarization, thereby prolonging the service life of the vacuum sealing ring.
Description
Technical field
The utility model relates to a kind of vacuum storage tank shell safety installations that can guarantee vacuum storage tank safety, belongs to the special-purpose safety installations of vacuum storage tank and makes the field.
Background technique
Publication number CN1955525A, title " antivoid valve ", antivoid valve (5) comprises the valve rod supporting member (610) of hole (603) assembling by the bottom of main body (600), its top with contact closure disc (630) and have fin (611) and the ring seat (620) of boss (612) is assembled; Sleeve (640) with the valve rod (660) of boss (612) assembling of valve rod supporting member (610) and supporting and closure disc (630) assembling; The screen of assembling with the bottom of valve rod supporting member (610) covers (670); With the screen (690) that screen lid (670) and screen cover (680) are assembled, the screen cover be placed under the screen (690) and therein the heart have air hole (681); Assemble and prevent the snap ring (650,651) that screen (690) moves up and down with the sleeve (640) at the center of passing screen (690).Its deficiency: be not suitable for the vacuum storage tank.
The model utility content
Purpose of design: avoid the deficiency in the background technique, design a kind of vacuum storage tank shell safety installations that can guarantee vacuum storage tank safety.
Design proposal: in order to realize above-mentioned purpose of design.Vacuum storage tank shell safety installations is installed in the top of vacuum storage tank, and inside is vacuum state, inside and outsidely pushes down capping and reaches sealing effect by atmospheric.Under the normal state, inside and outside differential pressure is about 0.1MPa.When urgency such as inner container leakage etc. needs pressure release, when pressure inside surpasses barometric pressure and adds the gravity of upper top cover, will the emergency opening exhaust, the safety requirement of outer container in reaching.
Technological scheme: vacuum storage tank shell safety installations; is connected with vacuum storage tank top around the circular envelope seat, upper end-hole is led to vaccum seal ring and circular shrouding is and is tightly connected and inside is vacuum state, protecting jacket 1 is enclosed within the top of circular shrouding 2 and the lower end of protecting jacket 1 is connected with vacuum storage tank top.
The utility model is compared with background technique, the one, the inside and outside of vacuum storage tank shell safety installations pushed down capping by barometric pressure, and be not only simple in structure, practical, and when pressure inside adds the gravity of upper top cover above barometric pressure, will the emergency opening exhaust, the safety of outer container in guaranteeing; The 2nd, there are ventilated port, top can avoid again drenching with rain and Exposure to Sunlight around the containment vessel of vacuum storage tank shell, the working life of protection vaccum seal ring.
Description of drawings
Fig. 1 is the structural representation of vacuum storage tank shell safety installations.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.Vacuum storage tank shell safety installations; is connected with vacuum storage tank top around the circular envelope seat 4, the logical vaccum seal ring 3 of upper end-hole and circular shrouding 2 be and be tightly connected and inside is vacuum state, protecting jacket 1 is enclosed within the top of circular shrouding 2 and the lower end of protecting jacket 1 is connected with vacuum storage tank top.
Described protecting jacket 1 is made of lasso and top cover, adopt bolt to be connected between top cover and the lasso and lasso around have vent hole, this vent hole has the ventilation and heat function, and top cover can be avoided drenching with rain and Exposure to Sunlight, protects the working life of vaccum seal ring.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of model utility mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (2)
1. vacuum storage tank shell safety installations; it is characterized in that: is connected with vacuum storage tank top around the circular envelope seat, upper end-hole is led to vaccum seal ring and circular shrouding is and is tightly connected and inside is vacuum state, protecting jacket is enclosed within the top of circular shrouding and the lower end of protecting jacket is connected with vacuum storage tank top.
2. vacuum storage tank shell safety installations according to claim 1, it is characterized in that: described protecting jacket is made of lasso and top cover, adopts bolt to be connected between top cover and the lasso and lasso has vent hole all around.
