详细介绍

矩形人孔是安装在储罐顶上的应急通气装置,通常与防火器、机械呼吸阀配套使用,既能避免因意外原因造成罐内急剧超压或真空时,损坏储罐而发生事故,又有起到阻火作用,是保护储罐的装置,特别适用于贮存物料以氮气封顶的拱顶常压罐。具有定压排放、定压吸入、开闭灵活、阻火、结构紧凑、密封性能好、可靠等优点。

矩形人孔一般由304,316L不锈钢钢板或者碳钢制作而成。

矩形人孔的结构介绍:

由于人孔安装在油罐的下层体圈上,防渗漏就显得特别重要。要求两法兰结合面保证其平直度,无飘扭现象。加强板和法兰应尽量在整块钢板上切割而不拼接。法兰和盖板上加工有密封圈,在施工中要特别注意保护。密封用3mm厚石棉橡胶垫片,不允许有折裂。安装人孔盖板上紧螺栓时,要成对角均匀用力,以防孔盖变形。

Rectangular manhole is an emergency ventilation device installed on the top of the storage tank. It is usually used with fire extinguishers and mechanical breathing valves. It can avoid accidents caused by sudden overpressure or vacuum in the tank due to accidents, and damage to the storage tank. It has a fire retardant effect and is a device to protect the storage tank, especially suitable for the vaulted atmospheric tank with nitrogen topped by the storage material. It has the advantages of constant pressure discharge, constant pressure suction, flexible opening and closing, fire resistance, compact structure, good sealing performance, and reliability.

Rectangular manholes are generally made of 304, 316L stainless steel plate or carbon steel.

Introduction to the structure of the rectangular manhole:

Since the manhole is installed on the lower body circle of the oil tank, leakage prevention is particularly important. The joint surface of the two flanges is required to ensure its flatness and no twisting. Reinforcing plates and flanges should be cut on the whole steel plate as far as possible without splicing. The flange and cover plate are processed with sealing rings, so special attention should be paid to protection during construction. 3mm thick asbestos rubber gasket is used for sealing, no cracks are allowed. When installing the manhole cover plate to tighten the bolts, force evenly at diagonal angles to prevent the manhole cover from deforming.
