Umehluko phakathi kwevalvu yebhabhathane evaliwe ethambile nevaliwe eqinile

Ivalvu yebhabhathane eqinile evalwe ngokuqinile:
I-butterfly valve hard seal ibhekisela ku: izinhlangothi ezimbili ze-sealing pair ziyizinto zensimbi noma ezinye izinto eziqinile. Lesi sici sinezakhiwo zokuvala ezingezinhle, kodwa sinokumelana nokushisa okuphezulu, ukumelana nokuguguleka, kanye nezakhiwo ezinhle zemishini. Njenge: insimbi + insimbi; insimbi + ithusi; insimbi + i-graphite; insimbi + i-alloy steel. Insimbi lapha ingaba futhi insimbi ephonswe, insimbi ephonswe, insimbi ephonswe nayo ingase ifakwe ngaphezulu, i-alloy efafazwayo.

I-valve yebhabhathane ethambile evaliwe:
I-valve yebhabhathane ethambile ibhekisela ku: uhlangothi olubili lwe-sealing pair luyinsimbi, olunye uhlangothi luyizinto ezithambile ezingezona ezensimbi. Lolu hlobo lokusebenza kahle kokuvala i-seal luhle, kodwa alumelani nokushisa okuphezulu, kulula ukuligqoka, alusebenzi kahle. Njenge: insimbi + irabha; insimbi + i-tetrafluorotype polyethylene, njll.

Isihlalo sokuvala esithambile senziwe ngezinto ezingezona ezensimbi ezinamandla athile, ubulukhuni kanye nokumelana nokushisa, ukusebenza kahle kungenza kube nokuvuza okungekho, kodwa impilo kanye nokuzivumelanisa nezimo zokushisa kubi. I-Hard seal yenziwe ngensimbi, futhi ukusebenza kokuvala kuphansi. Nakuba abanye abakhiqizi bethi akukho ukuvuza. I-soft seal ayikwazi ukuhlangabezana nezidingo zenqubo yengxenye yezinto ezibolayo. I-Hard seal ingaxazululwa, futhi lezi zimpawu ezimbili zingahambisana. Ngokuphathelene nokuvala, ukuvala okuthambile kuhle, kodwa manje ukuvala kokuvala okuqinile nakho kungahlangabezana nezidingo ezifanayo. Izinzuzo zokuvala okuthambile ukusebenza okuhle kokuvala, kodwa izinkinga zilula ukuguga, ukuguguleka kanye nempilo yesevisi emfushane. Impilo yesevisi ye-Hard seal inde, kodwa i-hard seal imbi kakhulu kune-soft seal.

Umehluko wesakhiwo ikakhulukazi ungokulandelayo:
1. Umehluko wesakhiwo
Ama-valve e-butterfly okuvala athambile avame ukuba maphakathi futhi aqondileivalvu yebhabhathane eliyindilinga, kanti izivalo eziqinile ngokuvamile ziyivalvu eyodwa engavamile, engavamile kabili kanye namavalvu amathathu engavamile emvemvane.

2. Ukumelana nokushisa
I-soft seal isetshenziswa endaweni yokushisa kwegumbi. I-hard seal ingasetshenziswa endaweni yokushisa ephansi, indawo yokushisa yegumbi, indawo yokushisa ephezulu kanye nezinye izindawo.

3. Ingcindezi
I-soft seal ingcindezi ephansi-ingcindezi evamile, i-hard seal ingasetshenziswa nasezimweni zokucindezela okuphezulu nakwezinye izimo zokusebenza.

4. Ukusebenza kokuvala
Ivalvu yebhabhathane enama-eccentric amathathu ingagcina ukuvalwa okuhle endaweni enomfutho ophezulu kanye nokushisa okuphezulu.

Ngenxa yezici ezingenhla, ivalvu yebhabhathane ethambile evaliwe ifanelekela ukuvulwa nokuvalwa okunezindlela ezimbili kanye nokulungiswa kwepayipi lokususa umoya nothuli, ukwelashwa kwamanzi, imboni yokukhanya, uphethiloli, imboni yamakhemikhali kanye neminye imboni. Ivalvu yebhabhathane evaliwe eqinile isetshenziswa kakhulu ekufudumaleni, ekuhlinzekweni kwegesi, igesi, uwoyela, i-asidi, i-alkali kanye neminye imvelo.

Ngokusetshenziswa kabanzi kwe-butterfly valve, ukufakwa kwayo okulula, ukulungiswa okulula kanye nesakhiwo esilula kusobala kakhulu. I-butterfly valve kagesi ethambile yokuvala, i-butterfly valve ethambile yokuvala umoya, i-butterfly valve eqinile yokuvala ngezikhathi eziningi yaqala ukufaka esikhundleni se-electric gate valve, i-stop valve njalo njalo.

Ngaphandle kwalokho, i-Tianjin Tanggu Water Seal Valve Co., Ltd. iyivalvu yesihlalo enwebekayo ethuthukisiwe kwezobuchwepheshe esekela amabhizinisi, imikhiqizo iyivalvu yesihlalo esinwebekayo ivalvu yebhabhathane, ivalvu yebhabhathane ye-lug, ivalvu yebhabhathane egxilile ephindwe kabili,ivalvu yebhabhathane e-eccentric ene-flange ephindwe kabili, ivalvu yokulinganisela, ivalvu yokuhlola amapuleti amabili e-wafer,I-Y-Strainernjalo njalo. Kwa-Tianjin Tanggu Water Seal Valve Co., Ltd., siyaziqhenya ngokuhlinzeka ngemikhiqizo yekilasi eliphezulu ehlangabezana nezindinganiso eziphakeme kakhulu embonini. Ngobubanzi bethu bama-valve kanye nokufakwa, ungasithemba ukuthi sizokunikeza ikhambi elifanele lohlelo lwakho lwamanzi. Xhumana nathi namuhla ukuze ufunde kabanzi ngemikhiqizo yethu nokuthi singakusiza kanjani.
