Yore makani mi mako butterfly valve ku pipeline?

Ka nyo yero yore mi mako dul pa butterfly valve ku pipeline nyoke jam tic utiye kakare nyo epe, ebi nyayu aloka loka ikum ngwec, pii, pii man pii pa pipeline valve. Yore mi mako valve ma pol utiye: mako flange, mako wafer, mako butt welding, mako threaded, mako ferrule, mako clamp, mako gire man kit mako mukende.

A. Ribu pa flange
Ribu pa flange ubedoflanged butterfly valveku flanges i thenge ario zo pa valve body, ma rwate ku flanges iwi pipeline, man ju ketho gi i pipeline ku bolting flanges. Flange connection ubedo yore ma pol pa dhanu tiyo kudu i valves. Flanges jupoko gi i convex surface (RF), flat surface (FF), convex man concave surface (MF), man mange.

B. Wafer connection
Valve ne juketho ikind flanges aryo, man valve body pawafer butterfly valvepol kare etiye ku vur mi ketho piny kara ekony ketho man ketho piny.

C. Solder connection
(1) Butt welding connection: Ajiki ario pa valve body jutiyo kudu i butt welding grooves nimakere ku butt welding requirements, ma rwate ku welding grooves mi pipeline, man juyike iwi pipeline ku welding.
(2) Kethu socket welding: Ajiki ario pa valve body jutiyu kudu nimakere ku yeny pa socket welding, man juyike ku pipeline ku socket welding.

D. Threaded connection
Threaded connections ubedo yore mayot mi rwate man pol kare jutiyo kudu pi valve ma nok. Kum valve juyike nimakere ku cik pa thread acel acel, man utiye kit thread aryo mi iye man thread mi woko. Eromo ku thwol ma iwi paip. Tye kit ario mi rwate:
(1) Sealing direct: Threads ma iye man ma woko timo tic mi sealing direct. Pi ni neno nia dul ne kud ucwir, pol kare jupongo ku moo mi lead, thread hemp man PTFE raw material tape; ikindgi PTFE raw material tape jutiyo kudu lee; piny eni utiye ku kero maber mi juku lyethu man etiye ku kero maber mi juku piny. Eyot ni tiyo kudu man kano. Ka jupoko, jucopo wothe woko zo, kum etiye filim ma mako ngo, ma ber uloyu uloyu ma sagu lead oil man thread hemp.
(2) Indirect sealing: tego pa thread tightening ucungo iwi gasket ikind planes aryo, kara gasket ubed ku tic mi sealing.

E. ferrule connection
Ferrule connection juyike kende i ngom para i oro ma ukadhu. Kite mi mako man ketho cinge ikume utiye nia ka nut ucung matek, ferrule ubedo ku tego, kara ngete pa ferrule ucwale i kor ot pa pipe, man thenge ma woko pa ferrule ucungo ikum joint i the tego. Iiye pa kum utiye ka rwate ku piny ma nyap, pi meno jucopo juku pii kud i iye. Calu valve mi jam tic. Ber pa kit mi rwate eni utiye:
(1) Dit ma nok, pek ma yot, kit ma yot, yot mi poko man ketho karacelu;
(2) Teko ma tek mi mako, tic ma lee, kero ma tek (1000 kg/cm 2 ), lyethu ma tek (650 ° C) man yeng yeng;
(3) Kit piny matung tung jucopo yero, maber pi jwigo lyethu;
(4) Piny ma mitere pi tic maber pa cuma epe malo;
(5) E ber pi ketho piny ma malu.
I kare eni, yore mi mako ferrule jutiyo kudu i jam tic moko ma nok i ngom para.

F. Grooved connection
Eni ubedo yore mi mako piny pio pio, emito bolts aryo kende, manvalve ma thum pa butterflyber pi pressure ma pinybutterfly valvesma pol kare jupoko. calu ve valve mi gwoko leng pa kum.

G. Dikiri mi iye ma ucungo kende
Lembe ceke ma malu eca tiyo ku tego ma woku pi jwigo tegu pa piny ma jutiyo kudu pi nwangu sealing. Ma e piny e gonyo kit mi mako cing giri ku tic ku kero ma rwom pare tiye ikind piny.
Sealing ring pare juketho i cone ma iye man etimo angle moko ku thenge ma nen i kind piny. Teko pa piny ma ikin piny eca cidho i cone ma iye man i ring ma juketho i iye. Iwi ng'et cone mi angle moko, tego ario ma tung tung juyubu, acel ku The center line of valve body is parallel with the outside, and other pressed on the inner wall of valve body. Teko ma tok cen utiye tego ma mako ngati gire. Ka rwom ma piny utiye malac, tego ma mako cinge utiye malac. Pieno, kit mi mako piny eni ber pi valve ma tek tek.
Ka juporo ku flange connection, egwoko piny madwong man dhanu, ento emito bende preload moku, wek ecopu tiyo kudu maber ka pressure i valve epe. Valves ma juyubu ku cik mi self-tightening sealing pol kare gibedo valves ma tek tek.

Tye yore madwong mi mako valve, calu, valve moko ma nok ma mitire ngo ni juwodh juwodhe ku paip; valve moko ma epe ku cuma gicokiri ku sockets man mange. Ju ma tiyu ku valve umaku jutim igi lembe nimakere ku lembe ma gitiye kudu.

Kano:
(1) Yore mi mako piny zo ucikere ni lubo cik ma rwate man ni nyuthu cik ma juketho pi juku valve ma juyeru kud i kethu.
(2) Pol kare, paip ma dit man valve gi rwate ku flange, man paip ma dit man valve gi rwate ku thread.
