Description

For the obturator in flammable and explosive fluid

Technical field

The present invention relates to a kind of material for being filled in flammable and explosive fluid, particularly the datonation-inhibition obturator of one.

Background technology

As everyone knows, the container of flammable and explosive fluid (as: petrol and diesel oil, liquefied gas, natural gas etc.) and pipeline etc. are housed and in storage, transport, conveying, use procedure, fire and explosive risks very easily occur, therefore must carry out datonation-inhibition process.

Fluid container or inner cavity of pipe can be divided into several " cells " effectively to contain flame transmission by this explosion-suppressing material, make blast pressure ripple sharp-decay, this structure has higher surperficial usefulness in unit volume simultaneously, has good heat absorptivity, and the temperature after combustion reaction is reduced, and suppression flame height, reduce heat radiation, the degrees of expansion of reacting gas reduces, and the force value in container increases not quite, make burning velocity not reach the limit velocity of blast, thus reach datonation-inhibition object.

As a kind of spherical filling body disclosed in No. 200780050216.7th, Chinese patent application, it disc-formed circular horizontal plane comprising multiple disc-formed circular vertical plane and extend parallel to each other.Circular open is positioned at horizontal plane center, sleeve shape body and the below to inner opening of described circular open and top to inner opening sleeve shape body together with form the through pipe of axis from the top to the bottom, wherein shell-like and to the internal diameter of the round of inner opening and the internal diameter of circular open identical.Vertical plane extends to the edge of each circular open from the outside genesis of spherical, and horizontal plane extends around described opening parallel respectively.Vertical plane extends to the half of the distance between the edge of the outward flange of the spherical on horizontal plane and the circular open of horizontal plane from the outside genesis of spherical.The connection of vertical plane up and between below formation horizontal plane and sleeve shape body.Opening is positioned at horizontal plane.Aperture arrangement is furnished with opening on the horizontal level respectively for making between vertical plane, and between vertical plane, is furnished with opening respectively on the horizontal level.But this spherical filling body exists following shortcoming or deficiency: (1), this spherical filling body exist the unreasonable structure in many places, spherical filling body filling in a reservoir and result of use can be affected; (2), the internal diameter size of its upper and lower sleeve shape body is identical, and cause complex manufacturing, production cost is too high, and production efficiency and qualification rate low; (3), it arranges multiple aperture at disc-formed circular horizontal plane, and this makes Design of Dies and production technology become more complicated.

A kind of nonmetal block explosion suppression sphere and for example disclosed in No. 201210231915.4th, Chinese patent application, comprising: ring segment, arcuate tab, upper tubular structure and lower tubular structure; Ring segment, arcuate tab, upper tubular structure and lower tubular structure form hollow grate shape spheroid; Upper tubular structure and lower tubular structure are arranged at the two ends up and down of spheroid respectively, coaxial with spheroid; Arcuate tab is symmetricly set in around tubular structure and lower tubular structure, and ring segment inserts in described arcuate tab along spheroid axes normal.But this nonmetal block explosion suppression sphere exists following shortcoming or deficiency: (1), on it, tubular structure is identical with the internal diameter size of lower tubular structure, cause complex manufacturing, production cost is too high, and production efficiency and qualification rate low; (2), it arranges multiple aperture on ring segment, and this makes Design of Dies complicated, and Mould Machining cost is high, easily goes wrong and not easily M R, production technology also can be made to become more complicated in use procedure.

For another example a kind of labyrinth-like spherical hollow obturator disclosed in No. 201210087376.1st, Chinese patent application, two ends are respectively arranged with coaxial tubular body, and the excircle around two tubular bodies is evenly connected with several segments; In the middle of two tubular bodies, be provided with a ring bodies be connected with each described segment; The larger large tubular body of a radius is respectively arranged with in the outside of each described tubular body; The position on the summit near described segment is provided with ring-type belt body.But, there is following shortcoming or deficiency in this labyrinth-like spherical hollow obturator: its large tubular body width is larger, and the opening of the compartment formed around the tubular body at two ends is less, therefore, when multiple obturator is arbitrarily piled up in a reservoir, very easily hinder the circulation of gas-liquid, and then affect the serviceability of container.

Therefore, provide that a kind of manufacturing process is simple, datonation-inhibition function is excellent becomes urgent problem in the industry for the obturator in flammable and explosive fluid.
