Isebenza njani ivalve yeglowubhu? Iingcebiso zevalve: Zifundise ukuchonga umgangatho wevalve yebhabhathane kunye neentlobo zevalve yeglowubhu eqhelekileyo
Ngokomzekelo, qwalasela itanki enkulu enesiciko. Amanzi angena kwitanki aze aphume kwintloko yesilinda. Intloko yesilinda isebenza njengenxalenye yokuvala yevalve. Ukuba isandla sikhuphukela kwintloko ye-cylinder, ilingana nomgaqo wokusebenza wevalve yokumisa. Ukuba uhambisa intloko ye-cylinder ngeenxa zonke, isebenza ngendlela efanayo nevalve yokumisa.

Iimpawu eziphambili:
1. Iinkcukacha zoyilo: GB/T 12235
2. Iinkcukacha zoqhagamshelwano:
1) I-BW ye-butt welding end: cofa i-GB/T 12224
2) Ukuphela kweFlange RF: cinezela i-JB79; GB/T 9113; HG20592
3, ukufunyanwa kwevalve kunye nokulinga:GB/T 13927; I-JB/T 9092
Sebenzisa olu lwakhiwo lulandelayo:
Vula uhlobo lwesakhelo senkxaso yebha
Isikrufu esiqhagamshelwe ivelufa enye yokuhamba; Uxinzelelo lwegesi luziqinisa ngokwalo ivelufa yokuqukuqela enye
Isitulo esinye sokutywina esingaphezulu

Iindawo zokuvula kunye nokuvala i-valve yeglowubhu ziyi-cylindrical disc, kwaye i-protruder surface iplani okanye i-spherical. I-disc yevalve ihamba ngokufanayo kwi-axis ye-fluid kumgca othe ngqo. Imowudi yokunyakaza ye-valve stem, kukho uhlobo lwentonga yokutyhala yombane (uhlengahlengiso lwe-valve stem, i-spindle ayilungelelanisi), kunye nokulungelelanisa uhlobo lwentonga ye-rotary (i-spindle kunye ne-valve stem rotation lifting, i-bolt eyakhelwe kwipleyiti yeoli). Ivalve yeglowubhu yeyokuvula kunye nokuvala kuphela, ukulungelelaniswa kunokulungiswa kunye nevalve ye-throttle.
Xa i-valve yeglobhu ivuliwe, ukuphakama okuhambelana nokuvulwa kwe-disc yi-25% ~ 30% ye-diameter yangaphandle, ukuhamba okupheleleyo kuye kwafikelela kwindawo enkulu kakhulu, ebonisa ukuba i-valve ibe ngaphezu kwendawo evulekile ngokupheleleyo. Ngoko ke, indawo evulekileyo epheleleyo ye-valve yeglobhu kufuneka igqitywe nge-disc stroke.
Iingcebiso zevalve: Zifundise ukuchonga umgangatho wevalve yebhabhathane kunye nesixhobo sokutywina sevalve yeglowubhu eqhelekileyo kunye nenqanaba lokuvuza lokutywinwa kwayo yeyona parameters iphambili yokuchonga inqanaba lesalathiso sexabiso levalve. I-valve ayilungile okanye ayibi, i-valve yesicelo semeko yokusebenza ekhethekileyo ingasetyenziselwa ixesha elide ingasetyenziselwa ixesha elifutshane kakhulu. Ngoko ke musani ukugweba ngokufanelekileyo. Kuxhomekeke kwindibaniselwano yeemeko zokusebenza. Ivalve yeglowubhu yePlunger: Ngale ndlela ivalve yeglowubhu lutshintsho lwevalve yeglowubhu esisiseko. Kule valve, iivalve ze-disc kunye noxinzelelo oluphezulu lwesango zidla ngokulungiswa ngokuhambelana ne-plunger rationale. I-disc iphuculwe kwi-plunger kwaye ixhunywe kwisiqu. Isitywina sifunyanwa ngamakhonkco amabini e-elastomer afunxelwe kwiplunger.
Chonga umgangatho wevalve yebhabhathane
Ukuqina kwevalve kukuvavanya ivalve. Unokufezekisa ukutywinwa okugqibeleleyo kuxhomekeke kwizinto zevalve, inkqubo yokuvelisa, inkqubo yokuvelisa kunye nemeko yokusebenza esetyenziswayo.
Izinto zokutywina zevalve kunye nenqanaba lokuvuza kwayo ukutywinwa ziiparamitha eziphambili zexabiso lesalathisi ukuchonga ukuphakama kwevalve. I-valve ayilungile okanye ayibi, i-valve yesicelo semeko yokusebenza ekhethekileyo ingasetyenziselwa ixesha elide ingasetyenziselwa ixesha elifutshane kakhulu. Ngoko ke musani ukugweba ngokufanelekileyo. Kuxhomekeke kwindibaniselwano yeemeko zokusebenza.
Ivalve yebhabhathane evula kunye nenxalenye yokuvala yipleyiti yebhabhathane emile okwedisk, ejikeleza kumgca wayo osembindini owahlukileyo kumzimba wevalvu ukuvula nokuvala okanye ukulungelelanisa ivalve ebizwa ngokuba yivalve yebhabhathane. Ivalve yebhabhathane ngokuqhelekileyo ingaphantsi kwama-90 degrees ukusuka ekuvuleni ukuya ekuvaleni. Ivalve yebhabhathane kunye nentonga yebhabhathane ayitshixwanga ngamandla. Ukuze ubeke ipleyiti yebhabhathane, kufuneka kufakwe isinciphisi seplanethi kwi-valve stem. Ukukhethwa kwe-reducers yeplanethi, kungekhona nje ukwenza i-butterfly plate kunye nenqanaba lokuvala, ukwenzela ukuba i-butterfly plate iphele kwindawo ehleliweyo, kodwa inokuphucula iimpawu zokusebenza zevalve.
Iimpawu zevalve yebhabhathane yemveliso inokumelana nobushushu, inqanaba loxinzelelo lokusebenza olukhoyo nalo liphezulu ngokwentelekiso, i-diameter ebizwa ngokuba yi-valve inkulu, ivalve ye-solenoid yenziwe nge-carbon steel, i-valve plate yokutywina ikhonkco yenziwe ngentsimbi endaweni yentsimbi. umsesane werabha. Iivalvu zebhabhathane ezinkulu neziphakathi eziqhubekayo zenziwa ngeepleyiti zentsimbi zokuwelda, ezisetyenziswa ikakhulu kubushushu obuphezulu obuphakathi kombhobho womsi kunye nombhobho wamafutha.
Iintlobo zevalve yeglowubhu eqhelekileyo
I-1, i-Angle globe valve kwi-valve ye-Angle globe, ulwelo lufuna kuphela ukutshintsha i-orientation kube kanye, ukwenzela ukuba uxinzelelo lwegesi ngevalve luncinci kunesakhiwo esisisiseko sevalve yeglowubhu.
I-2, ivalve yeglowubhu yohlobo lwe-DC ekuhambeni ngokuthe ngqo kunye nevalve yeglowubhu enobume be-Y, isango lepleyiti yetshaneli yeoyile kunye neyona ndlela iphambili yokuqukuqela kwi-slash, inqanaba lokuhamba lisezantsi kunevalve yeglowubhu esisiseko, ngoko ngokwe-bamboo Ze valve. ukuchasana nokuhamba kuhambelana nokuncinci.
3, ivalve yeglowubhu yohlobo lweplunger: le ndlela yevalve yeglowubhu lutshintsho lwevalve yeglowubhu esisiseko. Kule valve, iivalve ze-disc kunye noxinzelelo oluphezulu lwesango zidla ngokulungiswa ngokuhambelana ne-plunger rationale. I-disc iphuculwe kwi-plunger kwaye ixhunywe kwisiqu. Isitywina sifunyanwa ngamakhonkco amabini e-elastomer afunxelwe kwiplunger. Amatywina amabini e-elastomeric ahlulwe ngeclasp kwaye ahlanganiswe kwi-plunger ngumthwalo ofakwe kwivalve yokuhamba enye ngamantongomane evalve yokuqukuqela enye. I-Elastoseals iyasuswa kwaye inokwenziwa ngezinto ezahlukeneyo. Ivalve isetyenziswa ikakhulu “ukuvula” okanye “ukuvala” ivalve, kodwa iiplungers eziyilwe ngokukodwa okanye iclasp ekhethekileyo nayo ingasetyenziselwa ukulungisa ivalve.
