I-vallbes kunye ne-vilves zesango ziivalves ezimbini ngokubanzi. Oku kulandelayo lulwazi olucacileyo kumamkeli phakathi kwe-valves kunye ne-valvengo.
1. Imigaqo yokusebenza yahlukile. I-Globel Globa luhlobo lwe-stem vel, kwaye isandla sesandla sijikeleza kwaye siphuma ne-valve stem. I-Palve yeSango ngumjikelezo wesandla, kwaye i-valve iphakama. Ireyithi yokuhamba yahlukile. I-valve yesango ifuna ukuvulwa okugcwele, kodwa ivalve yeglove ayenzayo. I-Valve yeSango ayinamsebenzi wokungena ngaphakathi kunye nokukhuphela imfula, kwaye ivalve ye-globe ichaza i-inlets kunye neevenkile! I-valve yesango elingeniswayo kunye ne-valve ye-globe ivaliwe i-valves kwaye zezona vallo ezimbini ziqhelekileyo.
2. Ukusuka kwimbono yokubonakala, i-valve yesango ifutshane kwaye ide kune-Globel ivalve, ngakumbi ivalve ye-stem ifuna indawo ephezulu. Umhlaba wokutywina we-valve enesango unamandla athile okutywina, kwaye i-valve yayo ye-valve ihamba ngokuqinileyo kunye ne-valve yokutywina kwe-valves yoxinzelelo kunye nokuvuza. I-valve ye-valve ye-Wedge ye-Wedge Palve i-3 ~ 6 degrees. Xa ukuvalwa kokunyanzelwa kugqithisileyo okanye iqondo lobushushu litshintsha kakhulu, i-valve ilula ukuba ibambeke. Ke ngoko, amaqondo obushushu aphezulu kunye ne-valve yesango e-Wedge ephezulu bathathe amanyathelo athile okuthintela i-valve ikhutshiwe ukuba ingakhathalelwanga kwisakhiwo. Xa kuvulwa i-valve ye-valve kwaye ivaliwe, i-valve kunye ne-valve yokutywina i-valve ihlala inxibe, i-varity esondeleyo kwi-varve kwi-varve kwi-varve inkulu, kwaye ukunxitywa komhlaba okwi-valve kuphakame.
3. Xa kuthelekiswa neVood yeGlobe yeHlabathi, eyona nto iphambili ye-valve yesango kukuba ukunyangwa kokunyangwa kwamanzi kuncinci. Ukuchasana nokuchasana nokusebenza kwe-Ilve yesango eqhelekileyo malunga ne-0.08 ~ 0.12, ngelixa kuxhathisa i-Countial Allve ye-Global yeGlobe yeHlabathi malunga ne-3.5 ~ 4.5. Amandla okuvula kunye nokuvala amancinci, kwaye ophakathi unokuhamba ngeendlela ezimbini. Izinto ezingalunganga zizinto ezinzima, ubukhulu obuphakamileyo, kwaye zilula ukunxiba umphezulu wokutywina. Umhlaba wokutywina kwe-valbeb valve kufuneka ivalwe ngamandla agxothiweyo ukuze afezekise ukutywinwa. Ngaphantsi kwekhalithi efanayo, uxinzelelo lokusebenza kunye nesixhobo esifanayo se-drive, i-torque ye-globe ye-Globe yi-2,5 ~. Le ngongoma kufuneka ithathelwe ingqalelo xa uhlengahlengisa indlela yokulawula i-Torque yevalve engeniswayo.
Okwesine, indawo yokutywina ye-globe iveli inxibelelana kuphela xa ivaliwe ngokupheleleyo. I-Slip yomlinganiso phakathi kwe-valve evaliweyo evaliweyo kwaye umphezulu wokutywina incinci kakhulu, ke ukunxiba komhlaba wokutywina nayo incinci kakhulu. Ukunxiliswa kwe-Globe Valve Patve Palive ibangelwa bubukho bomdaka phakathi kwe-vall kunye nomphezulu wokutywina, okanye ngokuhla kwesantya esiphezulu ngenxa yemeko yokuvala. Xa ufaka ivalve ye-globe, ephakathi inokungena ezantsi kwe-valve kwaye ukusuka phezulu. Inzuzo yendawo ephakathi ephakathi kwe-valve kukuba ukupakisha akunaphantsi koxinzelelo xa ivalve ivaliwe, enokudlulisela i-valve, enokudlulisela i-pack xa i-pipeline iphantsi koxinzelelo. Ukungancedi kakuhle ukungena ezantsi kwe-valve kukuba i-throque yevali enkulu inkulu, malunga ne-1.05 ~ amaxesha e-stem inkulu, kwaye isiqu se-valve kulula ukugoba. Ngesi sizathu, ukungena esiqingqiweyo ukusuka ezantsi kuhlala kulungele kuphela i-vilber encinci ye-selber, kunye namandla e-vilve esebenza kwi-valve kwi valve xa ivalve ivaliwe kwi-350kg. Ukungeniswa kwe-provision engeniswayo i-valves ngokubanzi sebenzisa indlela yokungena kwiphakathi. Ukungancedi kakuhle ukungena okuphakathi kukuphambene nje kwendlela yokungena ezantsi.
5. Xa kuthelekiswa ne-valve yesango, izibonelelo ze-globe valves zisakhiwo esilula, ukusebenza kakuhle, kunye nokuloba ngokulula; Izinto ezingalunganga zizithintelo ezingamanzi kunye nokuvulwa okukhulu kunye nemikhosi yokuvala. Iibhova zesango kunye ne-valves zivumba ngokupheleleyo kwaye zivaliwe ngokupheleleyo. Zisetyenziselwa ukusika okanye ziqhagamshelane ne-Medium kwaye azilungelanga ukusetyenziswa njengeeValve. Uluhlu lwesicelo se-Globle Valvers kunye ne-valve yesango zimiselwa ziimpawu zabo. Kwiindlela ezincinci, xa kucinyiwe ukutywinwa kokutywinwa kokutywina, i-globe valve zihlala zisetyenziswa; Kwimibhobho yemibhobho yamanzi kunye nemibhobho yamanzi amakhulu, i-valves yesango isetyenziswa ngenxa yokuba ukuchasana kwesango kuyacelwa ukuba ibe mncinci.
