Masingenise umahluko phakathi kwendawo ye-globe kwaye aI-Palve yesango.
01
Ulwakhiwo
Xa indawo yokufaka inomda, nikezela ingqalelo kukhetho:
II-Palve yesangoUngaxhomekeka kwingcinezelo ephakathi ukuze uvale umphezulu wokutywina, ukuze ufezekise isiphumo sokuvuza. Xa kuvulwa kwaye kuvaliwe, i-valve kunye nomphezulu wokutywina kwesihlalo sevalve uhlala unxibelelana kwaye urabha omnye komnye, umphezulu wokutywina kulula ukunxiba, kwaye xaI-Palve yesangoIsondele ekuvaleni, umahluko phakathi koxinzelelo phakathi kwangaphambili nangasemva kombhobho omkhulu kakhulu, owenza ukuba umhlaba wokutywina unxibe kakhulu.
Ubume beI-Palve yesangoiya kuba nzima ngakumbi kunendawo ebonakalayo, kwimeko ye-caliber efanayo, ivalve yesango iphakamileyo kune-tulve, kwaye ilokhwe ye-globe inde kuneI-Palve yesango. Ukongeza,I-Palve yesangoyahlulwe yintonga ekhanyayo kunye nentonga emnyama. I-Vallives evaliweyo.
Ingaba isebenza kanjani
Xa ivalve ye-globe ivulwa kwaye ivaliwe, sisiqu esinyukayo, oko kukuthi, xa isandla sijikelezwe, isandla siya kujikeleza kwaye siphakamise isiqu. II-Palve yesangokukujikeleza i-handheel ukwenza i-valve stem ukuphakamisa intshukumo, kunye nesikhundla sesandla sabo sihlala singaguqukanga.
Ukuhamba kweentsilelo ziyahluka, kunyeI-valves yesangoUkufuna ukuvuleka ngokupheleleyo okanye ukuvala ngokupheleleyo, ngelixa i-hluaveves aziveli. Ivalve ye-globe ine-inlet ye-inlet echaziweyo kunye nendawo yokuphuma, kunye neI-Palve yesangoayinamsebenzi we-inlet kunye ne-Outlet.
Ukongeza,I-Palve yesangoonly has two states: full open or fully closed, and the stroke of opening and closing of the gate plate is very large, and the opening and closing time is long. Ukubetha kwendawo ye-valve ye-valve icocekile kakhulu, kwaye ipleyiti ye-valve ye-Globe ye-Globe inokuthintela kwindawo ethile ngokuhamba kohlengahlengiso lokuhamba. II-Palve yesangoinokusetyenziselwa kuphela i-torting kwaye ayinayo eminye imisebenzi.
Umahluko weNtsebenzo
Ivalve ye-globe inokusetyenziselwa ukunqunyulwa okunqunyulweyo kunye nokuhambahamba. The fluid resistance of the globe valve is relatively large, and it is more laborious to open and close, but because the distance between the valve plate and the sealing surface is short, the opening and closing stroke is short.
KubaI-Palve yesangoinokuvulwa ngokupheleleyo kwaye ivaliwe, xa ivuliwe ngokupheleleyo, ukunyangwa okuphakathi kwesitayile se-valvel phantse i-0, ke ukuvulwa kunye nokuvalwa kweI-Palve yesangoUya kuba nokusebenza nzima kakhulu, kodwa iplate yesango ikude kude nomphezulu wokutywina, kwaye ixesha lokuvula kunye nokuvala lide.

Ukufakwa kunye nokufakelwa kwendlela
Iziphumo zeI-Palve yesangoUkuhamba komgaqo kuzo zombini iindlela zokwenza izinto ziyafana, akukho mfuneko yokuba i-inlet kunye nendlela yokufaka kufakelo, kwaye iphakathi inokuhamba kuzo zombini iindlela. Ivalve ye-globe kufuneka ifakwe ngokungqongqo ngokungqinelana notolo lweqonga lomzimba, kwaye kukho i-vallve ecocekileyo ye-Glober, kwaye i-Globel "yeVenkile ye-Globe.
Ivalve evaliweyo iphantsi nangaphezulu, kwaye ukusuka ngaphandle kukho umbhobho ocacileyo ongekho kwinqanaba lesigaba esinye. II-Palve yesangoIndlela yokuhamba ikwindawo ethe tyaba. Ukubetha kweI-Palve yesangoinkulu kuneyona veli ye-globe.
Ukusuka kwimbono yokunganyangeki kwendlela, xa ivulekile, ukuchasana nokuhamba kwe-Ilanga leSango lincinci, kwaye ukunyangwa kwendawo yokumisa umthwalo kuyinto enkulu. Ukuchasana nokuchasana nokusebenza okuqhelekileyoI-Palve yesangoImalunga ne-0.08 ~ 0.12, amandla okuvula kunye nokuvala amancinci, kwaye ophakathi unokuhamba ngeendlela ezimbini. Ukuchasana nokuhamba kweenyawo ze-globes ze-globe ngamaxesha angama-3-5Iivalves zesango.Ukuvula nokuvala kufuneka kunyanzelwe ukuba kuvalwe ukutywina, i-spool ye-Glober ivaliwe, ngenxa yokuhamba komgangatho wokutywina, ngenxa yokuhamba komgangatho wokutywina, ngenxa yokuhamba kweyona ndlela iphambili kulungiso lwe-Glober.
Zimbini iindlela zokufaka ivalve ye-globe, enye kukuba i-Preium ingangenisa phantsi kwe-spool, ingeniso kukuba ukupakisha akuvalwanga xa ivalini ivaliwe xa i-pipeline iphantsi koxinzelelo; Ukungancedi kakuhle kukuba i-throle yevali enkulu inkulu, imalunga ne-1 ka-1 yendawo ephezulu, amandla e-axial ye-stem inkulu, kwaye i-valve ilula ukugoba.
Ke ngoko, le ndlela ilungele kuphela i-vils encinci ye-glober i-globes (DN50 okanye ngaphantsi), kwaye i-globe valve ihamba ngaphezulu kwe-DN200 isebenzisa i-DN200 ehamba phakathi. .

Ukutywinwa
Umhlaba wokutywina kwe-Globel i-vapezolal icala elincinci le-valveI-Palve yesangoitywinwe ecaleni kweplate ye-valve engxoweni, iziphumo zokutywina azilunganga njenge-valve valve, kwaye i-valve engundoqo akasayi kuba yivali yevaliji.
