Flame retardant ring for explosion-proof valve

Abstract

The invention discloses an explosion-proof valve anti-flaming ring. The ring comprises an anti-flaming ring boy and is characterized in that the anti-flaming ring body comprises a ring part and boss shoulders arranged on the ring part in a matched manner, the boss shoulders are evenly arranged along the circumference of the ring part, the cross section of the ring part is of a right hexagonal structure, a six-edge ring structure with the cross section in the right hexagonal shape is adopted in each boss shoulder, the radius of the anti-flaming ring body can be correspondingly adjusted throughthe size of the ring part, adjacent anti-flaming ring bodies with different radiuses can be in fit pressing connection through the side faces of the boss shoulders and the side face of the ring part,and the anti-flaming ring layer is formed. According to the anti-flaming ring, according to work requirements, the number of layers of anti-flaming rings can be adjusted, mounting flexibility is large, the shape is simple, production is easy, and production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of explosion-proof valve design, and in particular relates to a flame-retardant ring of an explosion-proof valve. Background technique [0002] Chinese invention patent application number 200710300274.2 discloses a "flame retardant sheet for explosion-proof valve". The middle of the sheet is extended. Although the inner edge of the sheet is bent up and down to form several grooves, these grooves are closed and half-type, which cannot significantly prolong the time for the airflow to pass through, and do not form a sufficient flow area / flow path, which cannot be well extinguished flame. [0003] Chinese invention patent application number 200810061321.7 discloses "an explosion-proof valve", the structure of which includes a panel, a seat plate and an internal flame retardant. An external flame retardant is also fixed between the panel and the seat plate. Both the outer flame retardant and the inner flame ...

Problems solved by technology

[0005] Chinese invention patent application number CN201210303682.4 discloses a "flame retardant sheet for explosion-proof valve". The gaps between the bosses form air passages, but the "Y"-shaped air passages are distributed in a plane, which fails to take into account the unevenness of the distribution of thermal air flow between layers. After the heat flow enters a certain layer of air passages, it can only The outflow of the air passage in this layer leads to the failure to fully utilize the effective space of the air passage gap to disperse the air flow, and it is also easy to cause the local heat flow to be too large, so that the flame cannot be completely extinguished in the passage.
