Uchungechunge lwevalvu yebhola elintantayo
- I-ARAN inobubanzi bamavalvu ebhola antantayo ngezinhlobo ezihlukene, izinto ezisetshenziswayo kanye nokuqokwa okunekhwalithi enhle nezindleko ezisebenzayo zamapayipi okuvalwa okujwayelekile.Idizayini yohlobo lwebhola elintantayo isebenza kusayizi omncane noma ama-valve ebhola anomfutho ophansi, inefomu lensimbi ehlanganisiwe noma ephonsiwe, ukwakheka komzimba we-valve wama-pcs ama-2 noma ama-3pcs.Uma kuqhathaniswa nevalve yebhola ye-trunnion, i-valve yebhola elintantayo ihlale ingama-valve angamasayizi amancane angekho mkhulu kuno-6 amayintshi.
- Ukuphela kwe-Flangeingcindezi ye-valve yebhola elintantayo usayizi otholakalayo:
- 150LBS usayizi 1/2IN~8IN,300LBS usayizi1/2”~6IN
- 600LBS usayizi1/2 IN~3IN,900~1500LBS usayizi1/2IN~2IN.
- SW/NPT/BW/NIPPLE ukuphelaumfutho we-valve webhola elintantayo usayizi otholakalayo
- 150LB~800LBS usayizi 1/2IN~2IN.
- 900~2500LBS usayizi 1/2IN~11/2IN.
- Yini i-valve yebhola entantayo?
- I-valve yebhola elintantayo isho ukuthi ibhola lintanta ekwakhiweni kwegumbi le-valve, isihlalo simi ngomzimba, futhi ibhola lisekelwa isiqu.Ukuxhumana kwesiqu nebhola ekuhambeni kwekota.Ibhola elintantayo phakathi kwezihlalo zamavalvu bese usebenzisa umugqa ophakathi nendawo icindezela ibhola liye phansi nomfula ukuze livaleke kahle futhi ivalvu ivalwe.I-valve ingahlanganiswa ngendlela ephindwe kabili, kodwa iqinile kuphela ngaphansi komfula.
- Siyini isici se-valve yebhola elintantayo?
- Ibhola elintantayo liyivalvu ehlangene yosayizi omncane kanye ne-torque ephansi.
- Impahla yomzimba yevalvu inesimo sensimbi efojiwe kanye nensimbi ecijile, umzimba wevalvu ngokuvamile uzoba yiziqephu ezimbili noma izingcezu ezintathu, kanye nomzimba wenyunyana.
- ● Idizayini enokwethenjelwa yophawu lwesihlalo
- I-valve yebhola elintantayo evamile yamukela isakhiwo sokuvala isihlalo esithambile.Lapho ingcindezi ephakathi nendawo iphansi, indawo yokuxhumana yendandatho yophawu nebhola incane, kodwa indawo yokuxhumana yesihlalo nebhola kuthola isilinganiso sokuvalwa kwebanga eliphakeme ukuze kuqinisekiswe ukuvaleka kuqinile.Lapho ingcindezi ephakathi nendawo iphakeme, indawo yokuxhumana ye-seal nebhola iba ngaphezulu, futhi indandatho yokuvala isihlalo ingabekezelela ukuphonswa okuphakathi okuphezulu ngaphandle kokulimala.
- ●Idizayini yeSakhiwo esingashisi esihlalweni, i-flange emaphakathi nesiqu
- Esimeni somlilo , iringi yesihlalo eyenziwe nge-PTFE noma ezinye izinto ezingezona ezensimbi izobola noma yonakaliswe ngaphansi kwezinga lokushisa eliphezulu futhi ibangele ukuvuza okuphezulu.Indandatho yophawu olungashi ifakwa phakathi kwebhola nesihlalo ukuze emva kokusha kwesihlalo esithambile se-valve, okuphakathi kuzophusha ibhola ngokushesha libheke ezansi nomfudlana zensimbi yokuvala uphawu ukuze yakhe insimbi eyisizayo esakhiweni sokuvala sensimbi, esingalawula ngempumelelo ukuvuza kwevalvu.Ngaphezu kwalokho, i-gasket yokuvala i-flange ephakathi yenziwe nge-gasket yesilonda sensimbi, engaqinisekisa ukuvala ngisho nangaphansi kokushisa okuphezulu.Idizayini yesakhiwo esingashi wevalvu yebhola elintantayo ihambisana nezidingo eziku-API 607, API 6FA, BS 6755 kanye ne-JB/T6899 njll.
- Umdwebo. Idizayini enokwethenjelwa yophawu lwesihlalo kanye nedizayini Yesakhiwo Sokuvikela Umlilo esihlalweni, i-flange emaphakathi nesiqu
- ●Esithembekile Valve Isiqu Seal
- Isiqu siwumklamo we-T ovimbela ukuphuma, ngisho nalapho igumbi le-valve ngaphansi kwengcindezi engavamile likhuphuka kanye nendlala yokupakisha exegayo, isiqu se-valve sizovimbela ukuphuma.
- Esimeni lapho ukupakishwa kwesiqu kushile, i-thrust bear ibekwa endaweni lapho ihlombe lesiqu kanye nokuthintana nomzimba ukuze kwakheke isihlalo sokuvala esihlanekezelwe.Amandla okuvalwa kwe-reverse seal azokwenyuka ngokuya ngokunyuka kwengcindezi ephakathi nendawo, ukuze kuqinisekiswe ukuvalwa kwesiqu okuthembekile ngaphansi kwengcindezi ehlukahlukene, kuvinjwe ukuvuza nokugwema ukusabalala kwengozi.
- Isiqu samukela isakhiwo sokuvala sokupakisha sohlobo lwe-V, ukupakisha okunjalo kungashintsha ngempumelelo ingcindezi namandla aphakathi nendawo edlala abe amandla okuvala isiqu.
- Ngokwezidingo zomsebenzisi, indlela yokucindezela yokupakisha elayishiwe ye-disc ingamukelwa ukwenza ukubekwa uphawu kokupakishwa kwesiqu kuthembeke kakhudlwana.
- ●Isakhiwo se-Anti-static
- I-valve yebhola ihlinzekwa ngesakhiwo se-anti-static.Ngosayizi ongaphansi kwe-DN25 nangaphezulu kwe-DN25 sebenzisa i-anti-static spring design ehlukile phakathi kwesiqu, umzimba nebhola khulula ugesi omile ovimbela umlilo noma ingozi yokuqhuma.
- ● Idivayisi yokukhiya i-valve
- Idivayisi yokukhiya i-valve iyadingeka ezizindeni ezibalulekile ezibalulekile lapho kungavinjelwa khona ukusebenza ngephutha kwe-valve ukuze kuvikelwe amapayipi.
