Uyini umsebenzi we-globe valve?

Ama-valve e-globe asetshenziselwa ukunqamula ukuhamba kwemidiya. Ama-valve e-globe afanele izikhathi ezidinga ukuvulwa njalo. Zisetshenziswa kakhulu ekukhiqizeni amakhemikhali. Izingxenye zokuvala zama-valve embulunga zingamadiski nezihlalo. Ukuze uvale ngokuqinile amavalvu embulunga, izindawo zokukhwelana zamadiski nezihlalo kufanele zibe phansi noma zifakwe umoya, futhi izinto ezimelana nokugqwala nezingagugi njengethusi nensimbi engagqwali zingafakwa ezindaweni ezivaliwe. I-disc nesiqu se-valve yembulunga zixhunywe ngendlela enyakazayo ukuze kube lula idiski nesiqu ukuze zilingane eduze. Ukukhuphuka nokuwa kwe-disc ye-valve yomhlaba ngokuvamile kulawulwa yisiqu. Ingxenye engenhla yesiqu se-valve yembulunga iyisondo lesandla, futhi ingxenye ephakathi iwuchungechunge kanye nesigaba sokupakisha sokuvala. Umsebenzi wokupakisha ukuvimbela ukuvuza kwe-medium ngaphakathi komzimba we-valve eduze kwesiqu. Umsebenzi oyinhloko we-valve yembulunga epayipini lamakhemikhali ukusika noma ukuxhuma uketshezi. Izinga lokugeleza elilawulayo le-valve yeglobhu lingcono kunelo le-valve yesango. Kodwa i-valve yeglobe ayikwazi ukusetshenziselwa ukulawula ingcindezi nokugeleza isikhathi eside. Uma kungenjalo, indawo yokuvala ye-valve yembulunga ingase iguguleke phakathi nendawo futhi ukusebenza kokuvala kungacekelwa phansi. Ama-valve eglobhu angasetshenziswa emanzini, kumusi, emoyeni onciphayo nakwamanye amapayipi, kodwa awafanele amapayipi aphakathi nendawo ane-viscosity ephezulu, ukupheka kalula kanye nemvula, ukuze kugwenywe ukulimaza indawo evalekayo. Isimiso sokusebenza se-valve yeglobe ukuthi i-disc yevalve yeglowubu ihamba ibheke phezulu eduze komugqa omaphakathi wesihlalo, futhi kuncike ekuphendulweni kwentambo ye-stem, ukuze indawo yokuvala ye-disc yevalvu yomhlaba kanye nendawo yokuvala Izihlalo zinamathele ndawonye, ​​ngaleyo ndlela zinqamule ukuhamba kwe-medium. Ubuhle nobubi bamavalvu embulunga Izinzuzo ze-Globe Valve Globe valve ine-stroke encane esebenzayo kanye nesikhathi esifushane sokuvula nokuvala. I-valve yembulunga inempahla yokuvala enhle, ukungqubuzana okuncane phakathi kwezindawo zokuvala nempilo ende yesevisi. I-valve yembulunga inokusebenza okuhle kokulawula. Ububi be-valve yeglowubu Ubude bokufakwa kwe-valve yeglobu bukhulu, futhi ukumelana nokugeleza okuphakathi kukhulu. Ama-valve embulunga ayinkimbinkimbi ngesakhiwo futhi anzima ukuwakha nokuwanakekela. Ukugeleza kwe-valve yembulunga kudlula esihlalweni se-valve kusuka phansi kuya phezulu, esinokumelana okukhulu futhi kudinga amandla amakhulu lapho kuvulwa futhi ivala. Ama-valve eglobhu ngokuvamile awafaneleki okumaphakathi anezinhlayiya, i-viscosity ephezulu kanye nokupheka okulula. Ama-valve eglobhu avame ukusetshenziswa kumapayipi adinga ukuvuleka nokuvala ngokugcwele, futhi amapayipi omusi asetshenziswa kakhulu. Ukuxhumana phakathi kwevalve yeglobhu kanye nepayipi, kungaba ngesikulufu noma okuphekiwe.
