Abstract

The invention relates to a plastic pipeline fire retardant ring. The plastic pipeline fire retardant ring comprises an outer shell and an annular inner core. When heated, the annular inner core can be expanded and block a pipeline piercing opening, and accordingly spreading of the fire behavior along the opening is prevented. The outer shell wrapping the annular inner core is composed of a first side face shell and a second side face shell which are fixed through a first lug plate and a second lug plate. Due to the fact that the first lug plate is provided with a threaded hole, the first side face shell and the second side face shell can be rapidly assembled and disassembled only through screws and other fasteners, installing is achieved in a time and labor saving manner, and manpower and cost are saved. In addition, nuts, buckles and other components in traditional fire retardant rings are omitted, and therefore the situation that due to losing of components, the fire retardant ring loses original functions of the fire retardant ring can be avoided.

Description

technical field [0001] The invention relates to the technical field of fireproof equipment, in particular to a fire-stop ring for plastic pipes. Background technique [0002] Plastic pipes are widely used as drainage pipes because of their low cost, long service life, and convenient construction. However, when a fire occurs, the plastic pipes are easily softened and burned, and the fire will spread to other floors or rooms with the drainage pipes through the hole. , resulting in significant losses. Therefore, the measures taken are to install a fire retardant ring on the floor or wall through which the drain pipe passes, so that it expands and seals the drain pipe to prevent the fire from spreading to the upper floors. Existing flame arresters require many parts for assembly, and there is a risk of falling off and being lost. In addition, too many parts are time-consuming and labor-intensive to install. SUMMARY OF THE INVENTION [0003] The purpose of the present inventi...
