Umehluko phakathi kwevalve uvemvane evalwe ngokuthambile futhi evalwe ngokuqinile

I-valve uvemvane evalwe kanzima:
Isivalo esiqinile se-butterfly valve sibhekisela kulokhu: izinhlangothi ezimbili zepheya yokuvala izinto zensimbi noma ezinye izinto eziqinile. Lolu phawu lunezici ezingezinhle zokuvala, kodwa lukwazi ukumelana nezinga lokushisa eliphezulu, ukumelana nokugqokwa, kanye nezakhiwo ezinhle zemishini. Okufana njengokuthi: insimbi + insimbi; insimbi + yethusi; insimbi + graphite; insimbi + i-alloy steel. Insimbi lapha ingase futhi ibe insimbi ekhonjiwe, insimbi ekhonjiwe, insimbi ye-alloy ingase futhi igqitshwe, i-alloy yokufafaza.

Ivalve uvemvane evalekile ethambile:
Isivalo esithambile se-Butterfly valve sibhekisa ku: izinhlangothi ezimbili zepheya yokuvala impahla yensimbi, olunye uhlangothi luyimpahla enwebekayo engeyona eyensimbi. Lolu hlobo lokusebenza kokuvala uphawu kuhle, kodwa hhayi ukumelana lokushisa eliphezulu, kulula ukugqoka, mechanical kabi. Okufana: insimbi + irabha; insimbi + i-tetrafluorotype polyethylene, njll.

Isihlalo esithambile sokuvala senziwe ngezinto ezingezona ezensimbi ezinamandla athile, ubulukhuni nokumelana nezinga lokushisa, ukusebenza kahle kungenza ukuvuza kwe-zero, kodwa impilo nokuzivumelanisa nezimo lokushisa akukuhle. Isigxivizo esiqinile senziwe ngensimbi, futhi ukusebenza kokuvala kuphansi kakhulu. Nakuba abanye abakhiqizi bathi zero ukuvuza. Ukuvalwa okuthambile akukwazi ukuhlangabezana nezidingo zenqubo zengxenye yezinto ezigqwalayo. Izimpawu eziqinile zingaxazululwa, futhi izimpawu ezimbili zingaphelelisana. Mayelana nokubekwa uphawu, ukubekwa uphawu okuthambile kuhle kakhulu, kodwa manje ukubekwa uphawu okunzima nakho kungahlangabezana nezidingo ezihambisanayo. Izinzuzo zokubeka uphawu okuthambile ukusebenza kahle kokuvala, kodwa okubi kulula ukuguga, ukuguga kanye nempilo yesevisi emfushane. Impilo yesevisi ye-hard seal yinde, kodwa uphawu lubi kakhulu kunophawu oluthambile.

Umehluko wesakhiwo ikakhulukazi umi kanje:
1. Ukwehluka kwesakhiwo
Ama-valve uvemvane avala uphawu athambile ngokuvamile anomugqa omaphakathi futhii-valve ye-butterfly egxilile, kanye nama-hard seal ngokuvamile ama-eccentric awodwa, ama-double eccentric kanye nama-valve uvemvane angama-eccentric amathathu.

2. Ukumelana nezinga lokushisa
I-Soft seal isetshenziswa endaweni yokushisa yegumbi. Uphawu oluqinile lungasetshenziselwa izinga lokushisa eliphansi, izinga lokushisa lekamelo, izinga lokushisa eliphezulu nezinye izindawo.

3. Ingcindezi
I-Soft seal ephansi yokucindezela okuvamile, uphawu oluqinile lungasetshenziswa futhi ekucindezelweni okuphezulu nezinye izimo zokusebenza.

4. Ukusebenza kokubeka uphawu
I-valve ye-butterfly ene-eccentric emithathu ingagcina uphawu oluhle ekucindezelweni okuphezulu kanye nendawo yokushisa ephezulu.

Uma kubhekwa lezi zici ezingenhla, i-valve uvemvane evalekile ilungele ukuvuleka nokuvalwa kwezindlela ezimbili kanye nokulungiswa kwepayipi lokungena komoya kanye nokukhipha uthuli, ukwelashwa kwamanzi, imboni yokukhanya, i-petroleum, imboni yamakhemikhali nezinye izimboni. I-valve uvemvane evalwe kanzima isetshenziswa kakhulu ukufudumeza, ukuhlinzekwa kwegesi, igesi, uwoyela, i-asidi, i-alkali nezinye imvelo.

Ngokusetshenziswa okubanzi kwe-valve ye-butterfly, ukufakwa kwayo okulula, ukugcinwa okulula kanye nesakhiwo esilula kusobala nakakhulu. I-valve uvemvane evala uphawu ethambile, i-pneumatic soft sealing butterfly valve, i-valve uvemvane evaleka kanzima ezikhathini eziningi yaqala ukushintsha i-valve yesango likagesi, ivalve yokumisa njalonjalo.

Ngaphandle kwalokho, i-Tianjin Tanggu Water Seal Valve Co., Ltd. iyi-valve yesihlalo esinwebekayo esezingeni eliphezulu esekela amabhizinisi, imikhiqizo i-elastic seat wafer butterfly valve, i-lug butterfly valve, i-valve ye-butterfly ephindwe kabili,i-valve ye-butterfly ephindwe kabili ye-flange, i-valve yebhalansi, i-wafer dual plate check valve,I-Y-Strainernjalo njalo. E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyaziqhenya ngokuhlinzeka ngemikhiqizo esezingeni eliphezulu ehlangabezana namazinga aphezulu embonini. Ngohlu lwethu olubanzi lwama-valve nokufakwa, ungasethemba ukuthi sizokunikeza isisombululo esiphelele sohlelo lwakho lwamanzi. Xhumana nathi namuhla ukuze ufunde kabanzi mayelana nemikhiqizo yethu nokuthi singakusiza kanjani.
