Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 4, a vent pipe sealing structure for a clean area of a factory building comprises a flange 2 connected to an end of a vent pipe 1, wherein during fixing, the flange 2 is fixedly clamped by a plurality of bolts, a sealing ring 3 is embedded in the flange 2, the sealing ring 3 is made of an elastic material, and the sealing ring 3 is extruded and deformed during clamping;

a groove body is formed in one side of the flange 2, and a sealing ring 3 is embedded in the groove body;

the groove body comprises a first groove 21 and a second groove 22 which are continuously formed in the flange 2 from outside to inside, the first groove 21 and the second groove 22 are communicated and extend to the outer side of the flange 2, and an inclined surface is arranged on one side, away from the ventilation pipeline 1, of the first groove 21;

the edge of the sealing ring 3 is outwards extended with a first bulge 31 and a second bulge 32, the first bulge 31 and the second bulge 32 are respectively embedded in the first groove 21 and the second groove 22 to form a propping seal, the first bulge 31 is propped against the inclined surface of the first groove 21, a gap exists between the first bulge 31 far away from the inclined surface and the first groove 21, when the flange 2 is fastened by a bolt, the sealing ring 3 is deformed, the second groove 22 is extruded by the deformation expansion of the joint of the first bulge 31 and the second bulge 32, so that the second groove 22 is sealed, meanwhile, the first bulge 31 is displaced in the first groove 21 due to the inward extrusion force received by the sealing ring 3, and the propping of the inclined surface of the first bulge 31 and the inclined surface of the first groove 21 is more obvious at the moment, so that the first groove 21 is sealed, and the joint of the ventilation pipeline 1 is sealed.
