Abstract
The utility model discloses an explosion-proof opening sealing device of a low-temperature mobile liquid storage device. The explosion-proof opening sealing device comprises an explosion-proof opening cover which is in close fit with an explosion-proof opening and a cap which is fixedly connected with the explosion-proof opening, wherein the explosion-proof opening cover is arranged in the cap. The explosion-proof opening sealing device is characterized in that the explosion-proof opening cover comprises a cover plate part and a convex protrusion part which stretches into the explosion-proof opening, and a sealing ring is respectively arranged between the cover plate part and the edge of the explosion-proof opening and between the convex protrusion part and the inner wall of the explosion-proof opening. The explosion-proof opening sealing device has a good sealing effect, the transportation efficiency of the low-temperature mobile liquid storage device is further improved, and the service life of the low-temperature mobile liquid storage device is also further guaranteed.
Description
Technical field
The utility model relates to a kind of venting seal arrangement, refers to that especially a kind of low temperature moves the venting seal arrangement of liquid storage equipment.
Background technique
The sealability that present low temperature moves the venting of liquid storage equipment requires very strict, and present venting seal arrangement comprises the explosion-proof flap that is sealed and matched with the venting end and the block of fixedlying connected with venting, this explosion-proof flap is positioned at block, and the sealing between explosion-proof flap and the venting end becomes sealing device performance whether key.So move the particularity of liquid storage equipment for low temperature, this simple seal structure between the end of present explosion-proof flap and venting just can't satisfy, its reason is that low temperature moves liquid storage equipment in the central vibrations of can jolting of mobile operation, it is not good that original structure shows sealing effect, influence the vacuum life of liquid storage equipment interlayer, layer vacuum reduce directly cause in the quickening of boosting of a jar gas-phase space, the safety valve overpressure relief, caused leaking of a large amount of media like this, bring certain loss economically for the client, also have potential safety hazard simultaneously.
The model utility content
Technical problem to be solved in the utility model is: the venting seal arrangement that provides a kind of low temperature to move liquid storage equipment, this venting seal arrangement good sealing effect, make low temperature move liquid storage equipment conveying efficiency and further improve, guaranteed further that also low temperature moves the working life of liquid storage equipment simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of low temperature moves the venting seal arrangement of liquid storage equipment, comprise the explosion-proof flap that is sealed and matched with venting and the block of fixedlying connected with venting, this explosion-proof flap is positioned at block, described explosion-proof flap comprises a cover plate portion and stretches into the interior convex extension part of mouth of venting, between this cover plate portion and the venting mouth edge, be equipped with seal ring between the internal orifice wall of convex extension part and venting.
As a kind of preferred scheme, described venting is cylindrical shape, and described cover plate portion and convex extension part are cylindric, and the lower end surface of cover plate portion is provided with the seal ring mounting groove, and the outer cylinder of described convex extension part is provided with the seal ring caulking groove.
As a kind of preferred scheme, it is low-temperature tanker or tank container that described low temperature moves liquid storage equipment.
As a kind of preferred scheme, pass through bolt between described block and the venting, described block is provided with bolt and passes the hole, fixedly have on the block with bolt and pass the corresponding nut in hole site, corresponding position on the venting periphery wall arranges tapped blind hole, and bolts and nuts, tapped blind hole are threaded.
After having adopted technique scheme, effect of the present utility model is: because described explosion-proof flap comprises a cover plate portion and the interior convex extension part of mouth of stretching into venting, between this cover plate portion and the venting mouth edge, be equipped with seal ring between the internal orifice wall of convex extension part and venting.Therefore, this venting seal arrangement arranges two-layer sealing, no matter low temperature move liquid storage equipment vertical tremor or about vibrations, the double seal circle improves reliability, effectively guarantee the degree of vacuum of interlayer, so just reduced heat output to a great extent, guaranteed the physical property of cryogenic media, conveying efficiency is further improved, guaranteed further that also low temperature moves the working life of liquid storage equipment simultaneously

Embodiment
Below by specific embodiment the utility model is described in further detail.
The said upper and lower orientation of present embodiment is determined up according to venting 6 openings.
As Fig. 1, shown in 2, a kind of low temperature moves venting 6 seal arrangements of liquid storage equipment, comprise the explosion-proof flap 4 that is sealed and matched with venting 6, and the block 3 of fixedlying connected with venting 6, low temperature moves liquid storage equipment and is generally low-temperature tanker or tank container, this venting 6 is arranged on the shell 7 that low temperature moves liquid storage equipment, venting 6 is cylindrical shape, its internal orifice wall also is circular, this explosion-proof flap 4 is positioned at block 3, described explosion-proof flap 4 comprises a cover plate portion 41 and stretches into the interior convex extension part 42 of mouth of venting 6, described cover plate portion 41 and convex extension part 42 are cylindric, the outside dimension of the size of cover plate portion 41 and venting 6 is complementary, the interior caliber size of the peripheral dimension of convex extension part 42 and venting 6 is complementary, between 6 mouthfuls of edges of this cover plate portion 41 and venting, be equipped with seal ring 5 between the internal orifice wall of convex extension part 42 and venting 6.Concrete, the lower end surface of cover plate portion 41 is provided with seal ring 5 mounting grooves 43, and the outer cylinder of described convex extension part 42 is provided with seal ring 5 caulking grooves 44, corresponding, venting 6 internal orifice walls are provided with a ladder internal orifice cylinder.Two seal rings 5 are put into seal ring 5 caulking grooves 44 and seal ring 5 mounting grooves 43, the lower end surface of cover plate portion 41 compresses seal ring 5 seals itself and venting 6 upper-end surfaces, and the outer cylinder of convex extension part 42 compresses another seal ring 5 and ladder internal orifice cylinder fitted seal, and it is fixing by bolt 1 between described block 3 and the venting 6, wherein, described block 3 is provided with bolt 1 and passes the hole, fixedly have with bolt 1 on the block 3 and pass the corresponding nut in hole site 2, nut 2 endoporus are aimed at bolt 1 pipe via hole, corresponding position on venting 6 periphery walls arranges tapped blind hole, bolt 1 and nut 2, tapped blind hole is threaded.This block 3 can compress explosion-proof flap 4 downwards, and explosion-proof flap 4 ventings 6 are sealed and matched.
This venting 6 seal arrangements adopt 5 sealings of double sealing circle, have increased the reliability of sealing, no matter run into vibrations or about shake, all can guarantee sealing effect; When micro-leakage takes place in the sealing of first road, the sealing of second road will be played the effect of sealing, so just the possibility of revealing is further effectively reduced, on low temperature mobile devices such as tank car and tank container, effectively guaranteed the degree of vacuum of interlayer, so just reduced heat output to a great extent, guaranteed the physical property of cryogenic media, conveying efficiency is further improved.
