Title:
危険場所のシーリング・グランド
Document Type and Number:
Japanese Patent JP5148883
Kind Code:
B2
Abstract:
A sealing gland ( 20 ) suitable for use in a hazardous environment is adapted to prevent fluid flow, pressure transmission and flame propagation between the gland and the penetrant portions of insulated electrical wires passing therethrough, and within and along such penetrant portions. The improved sealing gland includes a tubular body ( 21 ), a first insulator ( 22 ), a sealant ( 23 ), a second insulator ( 24 ), a follower ( 25 ), and a cap ( 26 ). The sealing gland is so dimensioned and proportioned that when the cap is tightened on the body, the sealant will be deformed into fluid-tight pressure-sealed engagement with the body and wire to prevent fluid flow, pressure transmission and flame propagation between the gland and wires, and within and along the penetrant portions of the wires.
