I-valves, i-valve yesango, ibhotile yebhabhathane, i-valves kunye neevalves zebhola zingamacandelo okulawula amaxabiso kwiinkqubo ezahlukeneyo zokwenza imibhobho namhlanje. Yonke ivalve yahlukile ngembonakalo, isakhiwo kunye nokusetyenziswa okusebenzayo. Nangona kunjalo, ivalve ye-globe kwaye i-valve yesango ineempawu ezithile, kwaye kwangaxeshanye anomsebenzi wethambeka kumbhobho, kuyakubakho izihlobo ezininzi ezingakhange zinxibelelane nevali nganye. Ngapha koko, ukuba ujonga ngokusondeleyo, umahluko phakathi kwendawo ye-globe kwaye i-valve yesango isekhulu kakhulu.
- Ulwakhiwo
Kwimeko yendawo encinci yokufaka, kuyimfuneko ukuze unikele ingqalelo ekukhetheni:
I-valve yesango inokuvalwa ngokuqinileyo kunye nomgangatho wokutywina ngokuxhomekeka kwingcinezelo ephakathi, ukuze kufezekiswe isiphumo sokuvuza. Xa kuvulwa kwaye kuvaliwe, ivalve spool kunye ne-valve yesitulo sokutywina zihlala zinxibelelana nevali nganye, kwaye ke, xa umbhobho wombhobho omkhulu, wenza ukuba umqobo wokutywina unxibe kakhulu.
Isakhiwo se-valve yesango iya kuba yintsokotha ngakumbi kunento ebonakalayo, ethabathela kwixesha lentlawulelo, intinga yesango inde kune-valve yeqela. Ukongeza, i-valve yesango yahlulwe yaba yintonga eqaqambileyo kunye nentonga emnyama. I-Glob Goobe ayikho.
- Sebenza
Xa ivalve ye-globe ivulwa kwaye ivaliwe, luhlobo lwe-stem theste, oko kukuthi, ivili lesandla lijikelezwe, kwaye ivili lesandla liya kujikeleza kunye ne-valve stem. I-valve yesango iguqula isifo sesandla, ukuze isiqu sentshukumo yokuphakamisa, kunye nesikhundla sesandla sabo sihlala singaguqukanga.
Ukuhamba kweereyithi kuyadihluka, ngamasango evava efuna ukuvalwa okugcweleyo, ngelixa i-hluaveves aziveli. I-Globe Global inolwalathiso lwe-inlet kunye nendawo yokuphuma, kwaye i-valve yesango ayinamsebenzi kunye nokuthengisa ngaphandle.
In addition, the gate valve is only fully open or fully closed two states, the gate opening and closing of the stroke is very large, the opening and closing time is long. I-Valve Plate ye-Plates Strooke ye-Globe Valve incinci, kwaye ipleyiti ye-valve ye-Globe inokuthintela kwindawo ethile ngokuhamba kohlengahlengiso lokuhamba. Ivalbengo yesango inokusetyenziselwa kuphela i-Trunyan kwaye ayinawo omnye umsebenzi.
- Intsebenzo
Ivalve ye-globe inokusetyenziselwa i-truncation kunye nommiselo wokuhambahamba. The fluid resistance of the globe valve is relatively large, and it is more laborious to open and close, but because the valve plate is short from the sealing surface, the opening and closing stroke is short.
Ngenxa yokuba i-valve yesango inokuvulwa ngokupheleleyo kwaye ivaliwe ngokupheleleyo, xa ivulekile ngokupheleleyo, ukungqubana okuphakathi kwesitayile se-valve phantse, kodwa ixesha lesango lide likude nexesha elide.
- Ukufakwa kunye nokufakelwa kwendlela
Iziphumo ze-valve yesango eziqukuqela kuzo zombini iindlela ziyafana, kwaye akukho mfuneko yokuba i-inlet kunye nendlela yokuphuma kofakelo, kwaye iphakathi inokuhamba kuzo zombini iindlela. Ivalve ye-globe kufuneka ifakwe ngokungqonge ngokungqongqo ukuchongwa komzimba we-valve, kwaye kukho isibonelelo esicacileyo kwicala lokungenisa elizweni kunye nokuhamba kwendawo ye-globe, kunye nokuhamba kwe-globe i-valve "e-China ivela phezulu.
I-Globe Globa iphantsi nangaphezulu, kwaye ukusuka ngaphandle kukho imibhobho ebonakalayo engakwinqanaba lesigaba. Imbaleki ye-valve yesango ikumgca othe tyaba. Ukubulawa kwentaba yevalve inkulu kuneyona ntlango ye-globe.
Ngokwembono yokunganyangeki kwendlela, ukunganyangeki kwendawo yesango kuncinanana xa kuvulekile ngokupheleleyo, kwaye ukunyangwa kokuhamba kwevalve ivutha ivalve i-valve yomiselo inkulu. Ukuhlakulela ukuPhulukana nokusebenza kwe-Ilve yesango eliqhelekileyo malunga ne-0.08 ~ 0.12, amandla okuvula kunye nokuvala amancinci amancinci, kwaye ophakathi unokuhamba kwiindlela ezimbini. Ukuchasana nokuhamba kweegesi ezivaliweyo ezivaliweyo ngamaxesha ama-3-5 amaXesha eSango. Xa kuvulwa kwaye kuvaliwe, kuyimfuneko ukunyanzela ukuvalwa ukuze kufezekiswe itywina, ivalve Spool ye-Globe incinci kakhulu, kuba ukuntywila kweyona nto iphambili kungcungcutheka kwi-Glober ye-Glober.
I-Global Ivalve inendlela ezimbini zokufakwa, enye yeyokuba iphakathi inokungena ngaphantsi kwevalve ivaliwe, kwaye i-valve ivaliwe, kwaye umsebenzi wokupakisha awukwenziwe phantsi koxinzelelo oluphambili phambi kwevalini; Ingxaki yokuba i-throle ye-valque eqhuba inkulu, imalunga ne-1 ka-1 yendawo yokuhamba, kwaye amandla e-axial ye-stem inkulu, kwaye i-valve ilula ukugoba.
Ke ngoko, le ndlela ilungele kuphela i-vils encinci ye-glober vilve (DN50 okanye ngaphantsi), kwaye i-globe valve ngaphezulu kwe-DN200 ikhethiwe ngendlela yemithombo yeendaba evela phezulu. .
- Ukutywinwa
Umhlaba wokutywina kwe-Globe Poupoidal icala elincinci le-vallve Kulungile njengendawo yehlabathi, nengxowa yevali ayiyi kuwa njengelivathi egwina.
