詳細介紹

進口氣瓶減壓閥
一、進口氣瓶減壓閥概述
品牌：美國歐可OKE
進口氣瓶減壓閥，Cylinder pressure reducing valve，就是將氣體鋼瓶中的高壓氣體減為實驗及工況所需的低壓氣體壓力的減壓閥。采用活塞式減壓結構，輸出壓力穩定，主要用于石油化工、化纖、照明電器、熱處理、冶金、玻璃、食品、醫藥、電子、國防航天、航空等主導領域的氮氣鋼瓶，氧氣鋼瓶，氦氣鋼瓶，氫氣鋼瓶，氬氣鋼瓶，乙炔鋼瓶的出口減壓。
各種氣體一般都是貯存在專用的高壓氣體鋼瓶中，使用時通過減壓閥使氣體壓力降至實驗所需范圍，再經過其它控制閥門細調，使氣體輸入使用系統。由于氣瓶內壓力較高，而氣焊和氣割和使用點所需的壓力卻較小，所以需要用減壓器來把儲存在氣瓶內的較高壓力的氣體降為低壓氣體，并應保證所需的工作壓力自始至終保持穩定狀態。進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定不變的調節裝置。

三、進口氣瓶減壓閥安裝說明
1、用下扳將減壓器進出氣接頭螺紋與氣瓶閥螺紋或高低壓側管路可靠的連接，一防止氣體泄漏。請勿轉動減壓器本體，應夾持本體，轉動螺母擰緊。
2、在安裝過程中，應確保減壓器進、出氣接頭與減壓器連接處不會發生松動，否則將會導致氣體泄漏，造成安全重大隱患。
3、清除氣瓶和管路系統與減壓器連接位置處的油污、水及灰塵，一旦雜質進入氣體減壓器內，將會導致污染氣體，阻塞氣體通道或產生其他麻煩。
4、如果管路上的螺紋變形，無法與氣體減壓器順利地裝上時，就不要強行連接，否則會導致管路系統及氣體減壓器上的螺紋損壞，從而引起嚴重事故。

四、進口氣瓶減壓閥操作說明
1、在氣體進入減壓器之前，須確認已對管路系統（含減壓器）按要求進行吹掃或進行抽真空處理。
2、在氣體進入減壓器之前，須確認減壓器調壓把手處于旋松狀態（逆時針旋松調壓把手），否則供氣初期的瞬時壓力有可能損壞膜片，從而導致減壓器失效，嚴重時會危及人身安全。
3、緩慢打開減壓器入口側的供氣閥門，用肥皂水火專用檢測儀對減壓器各連接處進行檢漏。
▲ 注意：打開供氣閥門時，人體不得正對或背對減壓器。
4、順時針旋轉減壓器調壓把手，將壓力（或流量）調到所需要的刻度指示位置，并用肥皂水或專用檢測儀對減壓器各連接處進行檢漏。
▲ 注意：在減壓器供氣過程中，如果發現有任何異常的機械振動、噪音、卡住或壓力異常升高的現象，表明減壓器已存在故障，應立即停止使用。

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.
