品牌：美國(guó)歐可OKE
進(jìn)口氣瓶減壓閥，Cylinder pressure reducing valve，就是將氣體鋼瓶中的高壓氣體減為實(shí)驗(yàn)及工況所需的低壓氣體壓力的減壓閥。采用活塞式減壓結(jié)構(gòu)，輸出壓力穩(wěn)定，主要用于石油化工、化纖、照明電器、熱處理、冶金、玻璃、食品、醫(yī)藥、電子、國(guó)防航天、航空等主導(dǎo)領(lǐng)域的氮?dú)怃撈浚鯕怃撈浚怃撈浚瑲錃怃撈浚瑲鍤怃撈浚胰蹭撈康某隹跍p壓。
各種氣體一般都是貯存在專用的高壓氣體鋼瓶中，使用時(shí)通過減壓閥使氣體壓力降至實(shí)驗(yàn)所需范圍，再經(jīng)過其它控制閥門細(xì)調(diào)，使氣體輸入使用系統(tǒng)。由于氣瓶?jī)?nèi)壓力較高，而氣焊和氣割和使用點(diǎn)所需的壓力卻較小，所以需要用減壓器來把儲(chǔ)存在氣瓶?jī)?nèi)的較高壓力的氣體降為低壓氣體，并應(yīng)保證所需的工作壓力自始至終保持穩(wěn)定狀態(tài)。進(jìn)口氣瓶減壓閥是將高壓氣體降為低壓氣體、并保持輸出氣體的壓力和流量穩(wěn)定不變的調(diào)節(jié)裝置。

Imported gas cylinder pressure reducing valve
I. Overview of imported gas cylinder pressure reducing valve
Brand: US Ouke OKE
The Cylinder pressure reducing valve is a pressure reducing valve that reduces the high pressure gas in the gas cylinder to the low pressure gas pressure required for the experimental and working conditions. It adopts piston type decompression structure and stable output pressure. It is mainly used in nitrogen steel cylinders, oxygen cylinders, helium gas in the leading fields of petrochemical, chemical fiber, lighting, heat treatment, metallurgy, glass, food, medicine, electronics, defense aerospace, aviation, etc. Cylinder, hydrogen cylinder, argon cylinder, acetylene cylinder outlet decompression.
All kinds of gases are generally stored in special high-pressure gas cylinders. When used, the gas pressure is reduced to the required range by the pressure reducing valve, and then finely adjusted by other control valves to make the gas input into the system. Since the pressure inside the cylinder is high, and the pressure required for gas welding and gas cutting and use points is small, a pressure reducer is required to reduce the higher pressure gas stored in the cylinder to a low pressure gas, and it should be ensured. The required working pressure is stable from start to finish. The imported cylinder pressure reducing valve is an adjusting device that reduces the high pressure gas to a low pressure gas and keeps the pressure and flow rate of the output gas constant.

Third, the import cylinder pressure reducing valve installation instructions
1. Use the lower wrench to connect the pressure reducer into the gas outlet thread and the gas cylinder valve thread or the high and low pressure side pipeline to prevent gas leakage. Do not turn the pressure reducer body. Hold the body and turn the nut to tighten.
2. During the installation process, it should be ensured that the connection between the inlet and outlet of the pressure reducer and the pressure reducer will not loosen, otherwise it will cause gas leakage and cause serious safety hazards.
3. Thoroughly remove the oil, water and dust from the connection between the cylinder and the piping system and the pressure reducer. Once the impurities enter the gas pressure reducer, it will cause polluting gas, block the gas passage or cause other troubles.
4. If the thread on the pipeline is deformed and cannot be installed smoothly with the gas pressure reducer, do not forcibly connect it. Otherwise, the thread on the piping system and the gas pressure reducer will be damaged, causing serious accidents.
Fourth, the import cylinder pressure reducing valve operation instructions
1. Before the gas enters the pressure reducer, it must be confirmed that the piping system (including the pressure reducer) has been purged or vacuumed as required.
2. Before the gas enters the pressure reducer, make sure that the pressure regulator handle is fully loosened (turn the pressure knob counterclockwise), otherwise the instantaneous pressure at the initial stage of air supply may damage the diaphragm, resulting in decompression. Invalid device, in severe cases, endangers personal safety.
3. Slowly open the air supply valve on the inlet side of the pressure reducer, and use a special tester for soap and water to check the connection of the pressure reducer.
?▲ Note: When opening the air supply valve, the human body must not face or face the pressure reducer.
4. Turn the pressure reducer knob clockwise to adjust the pressure (or flow rate) to the desired scale indication position, and use soapy water or a special detector to check the connections of the pressure reducer.
▲ Note: If any abnormal mechanical vibration, noise, jamming or abnormal increase in pressure is found during the supply of the pressure reducer, it indicates that the pressure reducer has a fault and should be stopped immediately.
