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, more particularly to a kind of datonation-inhibition obturator.

Background technology

It is well known that equipped with flammable and explosive fluid (such as：Petrol and diesel oil, liquefied gas, natural gas etc.) container and pipeline etc. exist Easily there is fire and explosive risks during storage, transport, conveying, use, it is therefore necessary to carry out datonation-inhibition treatment.

Fluid container or inner cavity of pipe can be divided into several " cells " effectively to contain the biography of flame by the explosion-suppressing material Broadcast, make blast pressure ripple sharp-decay, while the structure has surface efficiency higher in unit volume, with good suction It is hot, the temperature after combustion reaction is reduced, and suppress flame height, and heat radiation is reduced, the degrees of expansion of reacting gas reduces, Pressure value in container increases less, burning velocity is not reached the limit velocity of blast, so as to reach datonation-inhibition purpose.

A kind of spherical filling body as disclosed in Chinese patent application the 200780050216.7th, it includes multiple plate-likes Circular vertical plane and the disc-formed circular horizontal plane for extending parallel to each other.Circular open is located at horizontal plane center, described Formed from the top to the bottom together with the inwardly open sleeve shape body of circular open and top and the inwardly open sleeve shape body of lower section Axially through pipe, the internal diameter of the wherein internal diameter and circular open of shell-like and inwardly open round is identical.It is vertical flat Face extends to the edge of each circular open from the outside genesis of spherical, and horizontal plane prolongs around the opening parallel respectively Stretch.Vertical plane extends to outward flange and the circle of horizontal plane of the spherical on horizontal plane from the outside genesis of spherical At the half at the distance between the edge of opening.Company of the vertical plane up and between horizontal plane formed below and sleeve shape body Connect.Opening is located in horizontal plane.Opening is arranged so as to be disposed with opening between vertical plane respectively on the horizontal level, And it is disposed with opening between vertical plane respectively on the horizontal level.However, the spherical filling body has the following disadvantages or not Foot：(1), there is the unreasonable structure in many places in the spherical filling body, can influence spherical filling body filling in a reservoir and use effect Really；(2), the internal diameter size of its upper and lower sleeve shape body is identical, causes complex manufacturing, and production cost is too high, and production efficiency and Qualification rate is low；(3), it sets multiple apertures in disc-formed circular horizontal plane, and this causes that mold design and production technology become It is more complicated.

A kind of and for example nonmetal block explosion suppression sphere disclosed in Chinese patent application the 201210231915.4th, including： Ring segment, arcuate tab, upper tubular structure and lower tubular structure；Ring segment, arcuate tab, upper tubular structure and lower tubular structure are constituted Hollow grate shape spheroid；Upper tubular structure and lower tubular structure are respectively arranged at the upper and lower ends of spheroid, coaxial with spheroid；Arch Piece is symmetricly set in around tubular structure and lower tubular structure, and ring segment is inserted perpendicularly into the arcuate tab along spheroid axis In.However, the nonmetal block explosion suppression sphere has the following disadvantages or not enough：(1), tubular structure and lower tubular structure thereon is interior Footpath size is identical, causes complex manufacturing, and production cost is too high, and production efficiency and qualification rate are low；(2), it is in annular Multiple apertures are set on piece, and this causes that mold design is complicated, mould high processing costs, are easily gone wrong during use and not Easy M R, can also make production technology become more complicated.

For another example a kind of labyrinth-like spherical hollow obturator disclosed in Chinese patent application the 201210087376.1st, two End is respectively arranged with coaxial tubular body, and several segments are uniformly connected with around two excircles of tubular body；At two Tubular body middle setting has a ring bodies to be connected with segment each described；It is respectively provided with the outside of each described tubular body There is the bigger big tubular body of a radius；The position on the summit near the segment is provided with ring-type belt body.However, the fan Palace shape spherical hollow obturator has the following disadvantages or not enough：Its big tubular body width is larger, and shape around the tubular body at two ends Into compartment opening again it is smaller, therefore, when multiple obturators arbitrarily pile up in a reservoir when, easily hinder gas-liquid circulation, And then influence the performance of container.
