Umahluko phakathi kwamatywina athambileyo kunye namatywina anzima beevali:

Okokuqala, nokuba yivali yebhola okanye aIbhotile yebhabhathane, njl.

Okokuqala, indlela yokwakhiwa

Itywina elinzima le-valve yebhola yitywina lentsimbi, kwaye zombini ibhola ekhatywayo kunye nesitulo siyintsimbi. Ukuchaneka komatshini kunye nenkqubo kunzima kakhulu, kwaye isetyenziswa ngokubanzi kwingcinezelo ephezulu, ihlala ingaphezulu kwe-35MPA. Amatywina athambileyo atywine phakathi kwentsimbi kunye nezinyithi, ezinje nge-NYLOLO \ PTFE, kunye nemigangatho yokwenziwa iyafana.

Okwesibini, izinto zokutywina

Itywina elithambileyo nelukhuniyo zizinto zokutywina kwesitulo sevali, kwaye itywina elinzima liyintoni na isihlalo sokuhamba kwe-valve ukuqinisekisa ukuchaneka kwe-valve nge-valve (ibhola), intsimbi engaqhelekanga kunye nobhedu. Ukutywinwa okuthambileyo kuthetha ukuba izinto zokutywina zifakwe kwisitulo se-valve yinto engekho mthethweni, kuba izinto zokutywina zinezinto zokutywina zine-elasticy, ke iimfuno zokuchazela ziya kuba ziphantsi kakhulu kunokuba zityhutyha nzima.

Okwesithathu, inkqubo yokwenziwa

Ngenxa yeshishini elininzi leekhemikhali, imeko yokusebenza yeshishini lomatshini inzima kakhulu, uninzi lunobushushu obuphakathi, kwaye ukusetyenziswa kwezinto ezahlukeneyo kungcono, kwaye ukulungiswa kwezinto kunokuphakanyiswa.

Ngapha koko, umgaqo-siseko we-valt eqinileyo yeTywina iyafana netywina elithambileyo, kodwa ngenxa yokuba litywina phakathi kwezinyithi, kuyafuneka ukuba kuthathelwe ingqalelo izinyithi, kwaye ibhola kunye nebhola kunye nendawo yokuhlala zihlala zifezekisa itywina. Umjikelo wemveliso we-valve ye-tenve enzima, ukulungiswa kunzima kakhulu, kwaye akukho lula ukwenza umsebenzi olungileyo wevalve enzima.

Okwesine, iimeko zokusetyenziswa

Amatywina athambileyo anokufikelela kumatywina aphezulu, ngelixa izitywina ezinzima zinokuphakama okanye ziphantsi ngokweemfuno; Amatywina athambileyo kufuneka abe yimcimi yempungutye, kuba amaqondo obushushu aphezulu, itywina letywina elithambileyo liya kuvuza, ngelixa itywina elinzima alinayo le ngxaki; Amatywina anzima anokwenziwa ngoxinzelelo oluphezulu, kodwa amatywina athambileyo akanakuyifumana; Ngenxa yengxaki yokugeleka okuphakathi, itywina elithambileyo alinakusetyenziswa ngamanye amaxesha (ezinjengeendaba ezithile ezonakalisayo); I-valve yokugqibela yeTywina ngokubanzi ibiza kakhulu kune-valve ethambileyo. Ngokuphathelele ukuvelisa, akukho mahluko mninzi phakathi kwezi zimbini, eyona nto iphambili ngumahluko phakathi kwezihlalo ze-valve, itywina elithambileyo alikho itywina, kwaye itywina elinzima yintsimbi.

Okwesihlanu, ekukhetheni izixhobo

Ukukhethwa kweevali ezithambileyo kunye ne-hards ze-hards ikakhulu kusekwe kwiNkqubo yePiedium, ubushushu kunye neXesha eliPhakamileyo linokuthathwa li-50, kwaye i-valt ye-valt iphezulu, ngaphandle kwetyholo eliqinileyo neliqinileyo, ukutywina inqanaba linokufikelela kwinqanaba le-6.
