Butterfly valve le pipeline asiloah thilri karlak pehtlaihnak lam thimnak cu a dik maw dik lo timi nih pipeline valve a kal, a thlet, a thlet le a luan khawhnak kha direct in a hnorsuan lai. A tlangpi in hmanmi valve pehtlaihnak lam hna cu: flange pehtlaihnak, wafer pehtlaihnak, butt welding pehtlaihnak, threaded pehtlaihnak, ferrule pehtlaihnak, clamp pehtlaihnak, mah tein aa kharmi pehtlaihnak le a dang pehtlaihnak phun hna an si.
A. Flange pehtlaihnak
Flange pehtlaihnak cuflanged butterfly valvevalve pum a donghnak pahnih ah flanges he, cu hna cu pipeline cung i flanges he aa tlakmi an si, cun flanges pawl kha bolt in pipeline chungah an chiah hna. Flange pehtlaihnak cu valve ah hman bikmi pehtlaihnak phun a si. Flanges cu a tlongmi cunglei (RF), a tlongmi cunglei (FF), a tlongmi le a tlongmi cunglei (MF), tbk.
B. Wafer pehtlaihnak
Valve cu flange pahnih karlak ah chiah a si, cun valve pum cuwafer butterfly valvea tlangpi in chiahnak le chiahnak caah a fawinak ding caah chiahnak kuang a ngei.
C. Solder pehtlaihnak
(1) Butt welding pehtlaihnak: Valve pum a donghnak pahnih cu butt welding herhmi ningin butt welding grooves ah an ser, cu hna cu pipeline i welding grooves he aa tlakmi an si, cun welding in pipeline cungah an fek.
(2) Socket hrennak pehtlaihnak: Valve pum a donghnak pahnih cu socket hrennak a herh ning in tuah a si, cun socket hrennak in pipeline he pehtlaihnak an tuah.
D. Threaded pehtlaihnak
Threaded pehtlaihnak cu a fawimi pehtlaihnak lam a si i valve hmete caah hman a si tawn. Valve pum cu hri pakhat cio ning in tuah a si, cun chunglei hri le lenglei hri phun hnih a um. Pipe cung i hri he aa tlak. Threaded pehtlaihnak phun hnih a um:
(1) Direct in kharnak: A chunglei le a lenglei hri nih direct in kharnak rian an ttuan. Pehtlaihnak cu a luang lo nakhnga, a caan ah thir chiti, hri hemp le PTFE thilri hri in an khahter tawn; cu hna lakah PTFE thilri hri cu tam deuh in hman a si; hi thilri nih hin rawkralnak a doh khawhnak a ttha i a ttha tukmi kharnak tthatnak a ngei. Hman le chiah a fawi. A tthen tikah, a tthawng lomi zukcawl a si caah a dihlak in hloh khawh a si, cucu lead oil le thread hemp nakin a tha deuh.
(2) Indirect sealing: hri hrennak thazaang cu vanlawng pahnih karlak i gasket ah a kal, cucaah gasket nih kharnak rian a ttuan.
E. ferrule pehtlaihnak
Ferrule pehtlaihnak cu ka ram ah naite kum hna ah khan an rak ser. A pehtlaihnak le a kharnak phunglam cu nut kha a fek tikah, ferrule cu hneknak a tong, cucaah ferrule tthen cu pipe lenglei vampang ah a seh, cun ferrule lenglei cone cunglei cu hneknak tangah joint he aa pehtlai. A chunglei cu a tlawmmi cunglei he aa naih caah a luannak kha zumhawktlak tein kham khawh a si. Cu bantuk thilri valve hna. Hi bantuk pehtlaihnak nih a chuahpimi thatnak hna cu:
(1) A hmete, a rit lo, a sawhsawh mi dirhmun, a fawimi tthen le fonh;
(2) A fekmi pehtlaihnak thazaang, hmannak hmun kau, a sangmi hneknak doh khawhnak (1000 kg/cm 2 ), a sangmi lumnak (650 ° C) le hninhnak le hninhnak;
(3) Thilri phunphun thim khawh a si, rawkralnak dohnak caah aa tlakmi;
(4) A dikthliar in sernak caah a herhmi thil hna cu a sang lo;
(5) A sangmi hmun ah chiahnak caah a fawi.
Atu ah, ka ram ah a hmetemi valve thilri cheukhat ah ferrule pehtlaihnak phun cu hman a si cang.
F. A tlongmi pehtlaihnak
Mah cu a rannak in pehtlaihnak lam a si, hri pahnih lawng a herh, cuna tthenmi a donghnak butterfly valvethli tlawm caah aa tlakbutterfly valvescu hna cu an i tthen tawn. thianhhlimhnak valve tibantuk.
G. Chunglei mah tein aa hngatmi pehtlaihnak
A cunglei pehtlaihnak phun vialte nih cun kharnak tuah khawhnak ding caah a lenglei thazaang hmangin thilri hna i an hneknak kha an thlen. A tanglei nih hin a tlawm deuhmi hneknak hmangin mah tein aa hngatmi pehtlaihnak phun kha a langhter.
A kharnak hri cu a chunglei cone ah chiah a si i a kam cu a laifang lei hoih in angle pakhatkhat a ser. Medium nih a chuahpimi hneknak cu a chunglei cone ah a kal i cu hnuah sealing ring ah a kal. Angle pakhatkhat i a ummi cone cunglei ah, thilri pahnih a chuak, pakhat cu valve pum chung i a laifang line cu lenglei he aa tluk, cun a dang pakhat cu valve pum chunglei vampang he aa hngat. A hnu bik thazaang cu mah le mah aa hngatmi thazaang a si. A tlawm deuhmi hneknak a ngan deuhdeuh ahcun, mah le mah i hren khawhnak thazaang a ngan deuhdeuh. Cucaah, hi pehtlaihnak phun cu a sangmi hneknak valve caah aa tlak.
Flange pehtlaihnak he tahchunh ahcun, thilri le minung thazaang tampi a khamh, asinain preload tlawmpal zong a herh, cucaah valve chung i pressure a sang lo tikah zumhawktlak tein hman khawh a si. Mah tein aa hrenmi kharnak phunglam hmangin sermi valve pawl cu a tlangpi in a fakmi valve an si.
Valve pehtlaihnak phun tampi a um, tahchunhnak ah, chuah a hau lomi valve hmete cheukhat cu pipe in an hren hna; thir a si lomi valve cheukhat cu socket le a dangdang in an i pehtlaih. Valve hmangtu hna cu a bik in thil sining ning in zohkhenh an si awk a si.
Philhlo awk ah tial:
(1) Pehtlaihnak lam vialte nih aa tlakmi phunglam kha an zoh a hau i thimmi valve kha chiah lonak ding caah phunglam kha an fianter a hau.
(2) A tlangpi in, a nganmi pipeline le valve cu flange in an i pehtlaih, cun a hmetemi pipeline le valve cu hri in an i pehtlaih.
