人孔是安裝在儲(chǔ)罐頂上的安全應(yīng)急通氣裝置,通常與防火器、機(jī)械呼吸閥配套使用,既能避免因意外原因造成罐內(nèi)急劇超壓或真空時(shí),損壞儲(chǔ)罐而發(fā)生事故,又有起到安全阻火作用,是保護(hù)儲(chǔ)罐的安全裝置,特別適用于貯存物料以氮?dú)夥忭數(shù)墓绊敵汗?。具有定壓排放、定壓吸入、開(kāi)閉靈活、安全阻火、結(jié)構(gòu)緊湊、密封性能好、安全可靠等優(yōu)點(diǎn)。
人孔分為緊急泄壓人孔、防爆阻火呼吸人孔、罐頂人孔、罐壁人孔和帶芯人孔等。
人孔一般由304,316L不銹鋼鋼板或者碳鋼制作而成。
劃分
1、以通信管塊容量劃分
按人孔可容納規(guī)格為寬360mm、高250mm(標(biāo)準(zhǔn)的六孔管孔內(nèi)徑90mm水泥管塊,簡(jiǎn)稱標(biāo)準(zhǔn)塊)的管道斷面管塊或單孔管道管孔內(nèi)徑90mm的數(shù)量,分為大、中、小。
通信管道所設(shè)置人孔的大小,應(yīng)以通信管道的遠(yuǎn)期容量設(shè)置。不應(yīng)只考慮本期建設(shè)通信管道容量。
2、以人孔的通向劃分
以人孔的通向劃分可分為直通人孔、三通人孔、四通人孔和斜通人孔,具體詳見(jiàn)下表1。其中,斜通人孔又分為15°、30°、45°、60°、75°共五種。每種斜通人孔的角度,可適用于±7.5°范圍以內(nèi)。
3、以人孔上覆承受負(fù)荷能力劃分
以人孔上覆承受負(fù)荷能力劃分可分為汽-20級(jí)和汽-10級(jí)兩種
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.
