Description

Flange blowout prevention protective sleeve

Technical Field

The utility model relates to a pipe connection prevents spouting equipment, concretely relates to flange prevents spouting protective sheath.

Background

At present, two pipelines are connected through two flanges, and when liquid is conveyed in the pipelines, liquid leakage or spraying is easy to occur due to the problems of aging and the like of a pressure pad between the two flanges. In particular, in acetylene production enterprises, impurities such as hydrogen sulfide, phosphine and the like in crude acetylene are removed by using sulfuric acid and liquid alkali in a cleaning system, and due to strong acid-base corrosion, after a system pipeline is used for a long time, a pressure pad is easy to age at a flange joint, potential safety hazards caused by acid-base injection exist, and safety accidents caused by the burn of inspection personnel can be caused.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: in order to solve the problems existing in the prior art, the flange blowout prevention protective sleeve is provided.

The utility model provides a technical scheme of above-mentioned problem is: the utility model provides a protective sheath is prevented spouting by flange, including the rectangle cloth body, the upper portion of the rectangle cloth body transversely is provided with first ligature, the middle part transversely is provided with second ligature, the lower part transversely is provided with third ligature, every ligature comprises rubber strip and ribbon, the lower surface of rubber strip is pasted on the rectangle cloth body along length direction to the left end from the middle part, be provided with the belt loop in bank along length direction on the upper surface, the ribbon runs through in the belt loop and the ribbon head of ribbon is located the left end of rubber strip, first ligature is on last pipeline, second ligature is on flange, third ligature is on pipeline down.

Furthermore, be provided with a plurality of second ligatures between first ligature and the third ligature, when a plurality of short pipelines of being convenient for link to each other, all flange are good to single protective sheath ligature.

Further, the rubber strip width of second ligature is greater than the rubber strip width of first ligature and third ligature, and the ligature of second ligature is on the ring flange outer wall of two flange, and the rubber strip width of second ligature needs to be equal to or be greater than the sum of the ring flange thickness of two flange, and the rubber strip width of first ligature and third ligature then does not have the requirement, as long as can the ligature pipeline can.

Further, the thickness of the rubber strip is 5-25mm, and when the rubber strip is too thin, the rubber strip is not beneficial to a ribbon; the rubber strip is too thick and is not easy to bend.

Further, the rubber strip can also adopt a flexible plastic strip.

Furthermore, the rectangular cloth body is made of materials such as anti-corrosion canvas or plastic cloth.

Further, the rubber strip is arranged on the rectangular cloth body through rivets, so that the rubber strip and the rectangular cloth body are connected more firmly.

Furthermore, the ribbon adopts from locking-type stainless steel ribbon, ties up very conveniently.

Furthermore, the ribbon can also be used by adopting a hose clamp, so that the bundling tightness can be conveniently adjusted.

Use the utility model discloses the time, at first according to the diameter of last pipeline, lower pipeline and ring flange prune the rubber strip length of first ligature, third ligature, second ligature respectively, then wrap up the rectangle cloth body on flange and upper and lower pipeline, rectangle cloth body border overlaps, then hoop the rubber strip of second ligature on the flange lateral wall, tie up two pairs of butt joints of rubber strip with the ribbon, at last with first ligature, third ligature respectively tie up on the top tube, down the pipe can.

The beneficial effects of the utility model reside in that: adopt the utility model discloses the ligature is on flange and upper and lower pipeline, and second ligature piece has not only sealed the crack between two flanges, and the rectangle cloth body seals around flange moreover, can effectively prevent corrosive liquid's splash in the flange clearance, and the safety of the personnel of patrolling and examining of sufficient protection eliminates production potential safety hazard.
