Oxygen cylinder pressure relief valve imported with filter can effectively ensure the purity of outlet oxygen to avoid the structure of impurities in the gas is double meter, high-pressure detection of cylinder residual pressure, low-pressure detection of outlet pressure is simple and practical. Oxygen terminal control box is easy to control pressure. The valve body is high quality brass. Spring regulates stable outlet pressure. It has safety valve under it. Overpressure take-off protection is stable and reliable.
The output pressure is stable, the sealing performance is good, the valve body is equipped with filter device, and the use is convenient. It can be directly connected with oxygen cylinder for medical experiment, stable pressure control of industrial equipment, energy saving and emission reduction are preferred. This oxygen pressure relief valve is a special type of combustible gas pressure relief valve, which is suitable for domestic oxygen cylinders. The valve body is lightweight in structure, which uses the opening of the opening and closing parts in the control valve body to regulate the flow rate of the medium and reduce the pressure of the medium. At the same time, the opening of the opening and closing parts is regulated by the function of the pressure behind the valve, so that the pressure behind the valve can be kept within a certain range. The characteristic is to keep the pressure value of the outlet within a certain range when the inlet pressure is constantly changing. Inside.
【進(jìn)口氧氣減壓閥】工作原理:
氧氣減壓閥的高壓腔與鋼瓶連接,低壓腔為氣體出口,并通往使用系統(tǒng)。高壓表的示值為鋼瓶?jī)?nèi)貯存氣體的壓力。低壓表的出口壓力可由調(diào)節(jié)螺桿控制。
使用時(shí)先打開鋼瓶總開關(guān),然后順時(shí)針轉(zhuǎn)動(dòng)低壓表壓力調(diào)節(jié)螺桿,使其壓縮主彈簧并傳動(dòng)薄膜、彈簧墊塊和頂桿而將活門打開。這樣進(jìn)口的高壓氣體由高壓室經(jīng)節(jié)流減壓后進(jìn)入低壓室,并經(jīng)出口通往工作系統(tǒng)。轉(zhuǎn)動(dòng)調(diào)節(jié)螺桿,改變活門開啟的高度,從而調(diào)節(jié)高壓氣體的通過量并達(dá)到所需的壓力值。
減壓閥都裝有安全閥。它是保護(hù)減壓閥并使之安全使用的裝置,也是減壓閥出現(xiàn)故障的信號(hào)裝置。如果由于活門墊、活門損壞或由于其它原因,導(dǎo)致出口壓力自行上升并超過一定許可值時(shí),安全閥會(huì)自動(dòng)打開排氣。
【進(jìn)口氧氣減壓閥】安裝說明:
1)按使用要求的不同,氧氣減壓閥有許多規(guī)格。zui高進(jìn)口壓力大多為,低進(jìn)口壓力不小于出口壓力的2.5倍。出口壓力規(guī)格較多,一般為,zui高出口壓力為。
(2)安裝減壓閥時(shí)應(yīng)確定其連接規(guī)格是否與鋼瓶和使用系統(tǒng)的接頭相*。減壓閥與鋼瓶采用半球面連接,靠旋緊螺母使二者*吻合。因此,在使用時(shí)應(yīng)保持兩個(gè)半球面的光潔,以確保良好的氣密效果。安裝前可用高壓氣體吹除灰塵。必要時(shí)也可用聚四氟乙烯等材料作墊圈。
(3)氧氣減壓閥應(yīng)嚴(yán)禁接觸油脂,以免發(fā)生火警事故。
(4)停止工作時(shí),應(yīng)將減壓閥中余氣放凈,然后擰松調(diào)節(jié)螺桿以免彈性元件*受壓變形。
(5)減壓閥應(yīng)避免撞擊振動(dòng),不可與腐蝕性物質(zhì)相接觸。
3.其它氣體減壓閥
有些氣體,例如氮?dú)?、空氣、氬氣等永jiu性氣體,可以采用氧氣減壓閥。但還有一些氣體,如等腐蝕性氣體,則需要減壓閥。市面上常見的有氮?dú)?、空氣、、、、、水蒸氣等減壓閥。
這些減壓閥的使用方法及注意事項(xiàng)與氧氣減壓閥基本相同。但是,還應(yīng)該指出:減壓閥一般不用于其它氣體。為了防止誤用,有些減壓閥與鋼瓶之間采用特殊連接口。例如和均采用左牙螺紋,也稱反向螺紋,安裝時(shí)應(yīng)特別注意。
