Umahluko phakathi kwezitywina ezithambileyo nezilukhuni zeevalvu:

Okokuqala, nokuba yivalve yebhola okanye aivelufa butterfly, njl., kukho i-soft and hard seals, thatha i-valve yebhola njengomzekelo, ukusetyenziswa kwe-soft and hard seal of valves zebhola kuyahluka, ngokukodwa kwisakhiwo, kunye nemigangatho yokuvelisa i-valve ayihambelani.

Okokuqala, indlela yolwakhiwo

Isitywina esiqinileyo sevalve yebhola yintsimbi ukuya kwintsimbi, kwaye zombini ibhola yokutywina kunye nesihlalo yintsimbi. Ukuchaneka komatshini kunye nenkqubo kunzima kakhulu, kwaye isetyenziswa ngokubanzi kuxinzelelo oluphezulu, ngokuqhelekileyo ngaphezulu kwe-35MPa. Amatywina athambileyo ngamatywina phakathi kwesinyithi kunye neentsimbi ezingezizo, ezifana nenayiloni\PTFE, kunye nemigangatho yokuvelisa iyafana.

Okwesibini, izinto zokutywina

Isitywina esithambileyo nesinzima sisixhobo sokutywina sesihlalo sevalve, kwaye isitywina esiqinileyo sichaneke ngoomatshini kunye nesixhobo sesihlalo sevalve ukuze kuqinisekiswe ukuchaneka kokuchaneka kunye nesiseko sevalve (ibhola), ngokuqhelekileyo intsimbi engenasici kunye nobhedu. Ukutywinwa okuthambileyo kuthetha ukuba imathiriyeli yokutywina efakwe kwisitulo sevalve yinto engeyiyo eyentsimbi, kuba imathiriyeli yokutywina ethambileyo ino-elasticity ethile, ngoko ke iimfuno zokuchaneka kokulungiswa ziya kuba sezantsi kunezo zokutywinwa okunzima.

Okwesithathu, inkqubo yokuvelisa

Ngenxa yobuninzi beshishini lemichiza, indawo yokusebenza yeshishini loomatshini intsonkothile ngakumbi, uninzi lobushushu obuphezulu kunye noxinzelelo oluphezulu, ukuxhathisa ukukrwitsha okuphakathi kukhulu, kwaye i-corrosion yomelele, ngoku itekhnoloji iqhubekile, ukusetyenziswa kwezixhobo ezahlukeneyo kungcono, kunye nokusetyenzwa kunye neminye imiba inokuqhubeka, ukuze ivalve yebhola enetywina eliqinileyo ikhuthazwe ngokubanzi.

Enyanisweni, umgaqo wevalve yebhola eqinile ifana naleyo yetywina elithambileyo, kodwa ngenxa yokuba itywina phakathi kweentsimbi, kuyimfuneko ukuthathela ingqalelo ubudlelwane bobulukhuni phakathi kweentsimbi, kunye neemeko zokusebenza, yintoni i-medium ukuya, njl. Ngokuqhelekileyo, ukuqina kuyafuneka, kwaye ibhola kunye nesihlalo zihlala ziphantsi ukuze zifezekise itywina. Umjikelo wemveliso yevalve yebhola eqinile ide, ukusetyenzwa kuyinkimbinkimbi ngakumbi, kwaye akulula ukwenza umsebenzi olungileyo wevalve yebhola eqinile.

Okwesine, iimeko zokusetyenziswa

Amatywina athambileyo ngokubanzi anokufikelela kwizitywina eziphezulu, ngelixa amatywina aqinileyo anokuba phezulu okanye aphantsi ngokweemfuno; Izitywina ezithambileyo kufuneka zingabi nomlilo, kuba kumaqondo okushisa aphezulu, izinto eziphathekayo zesitywina esithambileyo ziya kuvuza, ngelixa i-hard seal ayinayo le ngxaki; Izitywina eziqinileyo zinokwenziwa ngokubanzi ngoxinzelelo oluphezulu, kodwa izitywina ezithambileyo azikwazi; Ngenxa yengxaki ye-medium flowing, itywina elithambileyo alinakusetyenziswa kwezinye iimeko (ezifana nemithombo yeendaba ezonakalisayo); Ivalve yokugqibela yokutywina eqinile ixabisa kakhulu kunevalve ethambileyo yokutywina. Ngokubhekiselele kwimveliso, akukho mmahluko omkhulu phakathi kwezi zibini, into ephambili ngumahluko phakathi kwezihlalo zevalve, isitywina esithambileyo singesi-metallic, kwaye isitywina esiqinileyo sisinyithi.

Okwesihlanu, ekukhetheni izixhobo

Ukukhethwa kweevalve zebhola ezithambileyo nezilukhuni zisekelwe kwinkqubo ephakathi, ubushushu kunye noxinzelelo, i-medium ngokubanzi iqulethe amasuntswana aqinileyo okanye igugile okanye iqondo lobushushu lingaphezulu kwama-degrees angama-200, kulungile ukukhetha izitywina ezinzima, ububanzi bukhulu kune-50, umahluko woxinzelelo lwevalve mkhulu, kunye netorque yevalve yokuvula ikwaqwalaselwa, kunye netywina eliqinileyo eliqinileyo xa i-valve ekhethiweyo ithambile kwaye i-valve ithambile. inqanaba lokutywina linokufikelela kwinqanaba lesi-6.

Ukuba unomdla kwi-resilient uhleliivelufa butterfly, ivalve yesango,Y-isihluzi, ivalve yokulinganisa,khangela ivalve, unokuqhagamshelana nathi nge-whatsapp okanye i-imeyile.
