详细介绍

人孔是安装在储罐顶上的安全应急通气装置,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,又有起到安全阻火作用,是保护储罐的安全装置,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、安全阻火、结构紧凑、密封性能好、安全可靠等优点。
  人孔分为紧急泄压人孔、防爆阻火呼吸人孔、罐顶人孔、罐壁人孔和带芯人孔等。
  人孔一般由304,316L不锈钢钢板或者碳钢制作而成。
  划分
  1、以通信管块容量划分
  按人孔可容纳规格为宽360mm、高250mm(标准的六孔管孔内径90mm水泥管块,简称标准块)的管道断面管块或单孔管道管孔内径90mm的数量,分为大、中、小
  通信管道所设置人孔的大小,应以通信管道的远期容量设置。不应只考虑本期建设通信管道容量。
  2、以人孔的通向划分
  以人孔的通向划分可分为直通人孔、三通人孔、四通人孔和斜通人孔,具体详见下表1。其中,斜通人孔又分为15°、30°、45°、60°、75°共五种。每种斜通人孔的角度,可适用于±7.5°范围以内。
  3、以人孔上覆承受负荷能力划分
  以人孔上覆承受负荷能力划分可分为汽-20级和汽-10级两种

The manhole is a safety emergency ventilation device installed on the top of the storage tank. It is usually used in conjunction with a fire extinguisher and a mechanical breathing valve. It can not only avoid the sudden overpressure or vacuum in the tank due to unexpected reasons, but also damage the storage tank and cause accidents. It has the function of safety fire prevention and is a safety device to protect the storage tank, especially suitable for the vaulted atmospheric tank whose storage material is capped with nitrogen. It has the advantages of constant pressure discharge, constant pressure suction, flexible opening and closing, safe fire resistance, compact structure, good sealing performance, safety and reliability.

Manholes are divided into emergency pressure relief manholes, explosion-proof fire-resistance breathing manholes, tank top manholes, tank wall manholes and core manholes.

Manholes are generally made of 304,316L stainless steel or carbon steel.

divide

1. Divided by the capacity of the communication pipe block

According to the number of pipe blocks with a width of 360mm and a height of 250mm (standard six-hole pipe holes with an inner diameter of 90mm, referred to as standard blocks), the manhole can accommodate the number of pipe blocks with an inner diameter of 90mm or a single-hole pipe with an inner diameter of 90mm. ,Small.

The size of the manhole set in the communication pipeline should be set according to the long-term capacity of the communication pipeline. We should not only consider the capacity of communication pipelines under construction in this period.

2. Divided by the passage of manholes

According to the division of manholes, it can be divided into straight manholes, three-way manholes, four-way manholes and oblique manholes. For details, see Table 1 below. Among them, the inclined manholes are divided into five types: 15°, 30°, 45°, 60°, and 75°. The angle of each oblique manhole can be applied within the range of ±7.5°.

3. According to the load bearing capacity of the overlying manhole

According to the load bearing capacity of the overlying manhole, it can be divided into two types: steam-20 grade and steam-10 grade.
