氧氣管路閥專用閥門特點
Characteristic
1、對于公稱壓力PNa1.6MPa、DN125~200采用內(nèi)旁通結(jié)構(gòu);DN250-~50O采用帶外旁通閥結(jié)構(gòu)。其目的是減小閥前、閥后的壓力差以避免高流速、高沖刷以及防止產(chǎn)生高溫，從而保證了氧氣管網(wǎng)的安全運行，同時也減小了操作力矩
2、介質(zhì)流向:PN≥1.6MPa、DN≤100介質(zhì)由閥瓣下方流入閥瓣上方(即低進高出)，DN≥125介質(zhì)由閥瓣上方流入下方(高進低出)。對于DN≥125的閥門采用介質(zhì)高進低出的流向，一方面是內(nèi)旁通閥結(jié)構(gòu)上的需要，另一方面由于介質(zhì)壓力的作用使閥門的關(guān)閉力大大減小。
3、該閥設(shè)有導靜電安全裝置,可避免因靜電產(chǎn)生火花。
4、與普通截止閥相比，氧氣管路用截止閥的支架部分采用全封閉式結(jié)構(gòu)，且壓緊填料時可以打開支架上的防護蓋板，起到了防油防塵的作用。并有明顯的禁油標記。
5、全部零件采用嚴格的脫指處理。
1. Inner bypass structure is adopted for the nominal pressure ranging PN≥1.6MIPa,DN125~2Q00;outer by pass valve for Dn250~5600, so as to reducepropost-vave pressure with a view to avoiding high strength, high scour and preventing from high temperature, with which guarantees safe operation foroxygen pipe network the moment reduces operating torque.
2.Flow diection for mediuom:.PN≥1.6MPa, Dn≤100 are to beused to the condition that the medium is flowed from underside to upside (i.e.lowintlowand high ouffow) whileDn≥125for the condition offiowing from upside to underside (i.e.igh inflow and low outlow), the reason for thelatter one can belisted as follows:Firstly, needs of innerbypass valve;Secondly , the onlofforce has been greatly reduced caused by medium pressure.
3.The valve is equipped with safe device for removing static electricity , with which can avoid producing fire by static electricity.
4.Compared with normal stop valve, the stand of this special valve adoptsfull-sealed structure, in which can open saieguarding cap on the standwhen pressing fillings with a view to preventing from oil & dust, the obvious symbol of Oil Forbidden is labeled therein.
5.The whole components has been degreased firmly.
安裝、使用、維護注意事項Points to note (Installation, Operation & Maintenance)
1、安裝時注意閥體上箭頭方向與介質(zhì)流動方向一致。
2、閹導線擰在兩側(cè)法蘭的接地螺栓上，并將其接地，導除閥門上內(nèi)的靜電。
3、操作閥門時手輪順時針旋轉(zhuǎn)閥門關(guān)閉，逆時針旋轉(zhuǎn)閥門開啟。對帶有內(nèi)旁通結(jié)構(gòu)的氧氣閥開啟時，先逆時針旋轉(zhuǎn)手輪打開副閥瓣，待閥門前后壓力差減小到O.3MAPa時，再繼續(xù)旋轉(zhuǎn)手輪打開主閥;對帶有外旁通閥的氧氣閥開啟時，首先打開旁通閥，待閥門前后壓力差減小到0.3MPa時，再打開主閥。關(guān)閉時先關(guān)主閥后關(guān)旁通閥。
4、該閥為全關(guān)、全開型。操作時應(yīng)緩慢進行，并不得當調(diào)節(jié)閥用。
5、維護時傳動部位涂不可燃的潤滑脂。
6、其余事項按冶金工業(yè)部《氧氣安全規(guī)程》和《鋼鐵企業(yè)氧氣管網(wǎng)若干技術(shù)規(guī)定》執(zhí)行。
本公司除生產(chǎn)氧氣管道用截止閥外，還生產(chǎn)氧氣管道用止回閥、球閥、儀表閥等閥類和配套法蘭、管件。材質(zhì)有不銹鋼、銅合金兩大類，歡迎廣大用戶根據(jù)需要選用。
1. When installing, the arrow direction on the valve body should accord with the flow direction of medium.
2.The conducting wire should be screwed to the ground bolts on both sides'flange and grounded so as to remove the static electricity on the valve.
3.CloselOpen when rotating hand wheel clockwise/anticlockwise:When opeming the oxygen valve equipped with inner bypass structure,rotates thehand wheel anticlockwise to open assistant disc until the pressure balance between the front and the back of the valve at 0.3MPa, then continues the rotating operation to open the main valve; as per outerbypass valve, opens bypassvave until he pressure balance at 0.3MAPa. then continues the rotatingthe main valve should be closed before bypass valve.
4.The valve employs full open/close: It should be operated slowly and can not be employed as regulating valve.
5.The incombustible grease should be smeared on the gear when maintaining.
6.The additional items can be operated in accordance with SafetyRegulation forOxygen and Certain Techica Regulations forPipe Network in SteelCorporations enacted by State Ministry of Metallurgical Industry.
Besides stop valve for oxygen pipeline, the valves such as the check valve , ball valve & meter valve for oxygen pipeline are also available in thecorporation while coupled flange & pipe fitting are supplied, in which stainless steel & copper alloy are used fortheir materal welcome to purchaseourproducts.
