Metal Seat Ball Valve VS Soft Seat Ball Valve

Zombini izivalo zebhola yesihlalo senyama kunye neevalvu zebhola ezithambileyo zezona zixhaphake kakhulu iivalvu zebhola, kwaye kukho iiyantlukwano ezininzi phakathi kwazo.

1.Ulwakhiwo

Ivalve yesihlalo sebhola yenyama ibhekiselele kwitywina phakathi kwentsimbi nentsimbi, kwaye ibhola yokutywina kunye nesitulo zombini ziyintsimbi.Isihlalo sevalve yebhola ehleli ethambileyo asiyontsimbi.

2.Izinto zokutywina

Ngaphantsi kweemeko eziqhelekileyo, i-valve yebhola yesihlalo senyama isetyenziswe ngokuchanekileyo yinto yokuhlala ukuze kuqinisekiswe ukuchaneka okuhambelanayo kunye ne-valve core (ibhola), ngokubanzi insimbi engenasici kunye nobhedu, ngelixa isitywina esithambileyo sithetha ukuba izinto zokutywina ezifakwe esihlalweni yintsimbi. izinto ezingezona zetsimbi , Ngenxa yokuba izinto zokutywinwa ezithambileyo zine-elasticity ethile, iimfuno zokuchaneka kokuchaneka ziya kuba ziphantsi kunezo zokutywinwa kwesinyithi.

3.Ukusebenzisa

Ngokwemiqathango yokusetyenziswa, izitywina ezithambileyo ngokubanzi zinokufikelela kumanqanaba aphezulu, ngelixa izitywina zetsimbi zinokuba phezulu okanye ziphantsi ngokweemfuno;amatywina aqinileyo anokuveliswa ngokubanzi ngoxinzelelo oluphezulu, kodwa amatywina athambileyo awakwazi;izitywina ezithambileyo zifuna ukukhuselwa komlilo, kuba Ngaphantsi kobushushu obuphezulu, izinto eziphathekayo zesitywina esithambileyo ziya kuvuza, kodwa isitywina sensimbi asinayo le ngxaki;itywina elithambileyo alinakusetyenziswa ngamanye amaxesha ngenxa yengxaki yendawo ehambayo (njengemithombo yeendaba eyonakalisayo);ivalve yentsimbi ibiza kakhulu kunetywina elithambileyo.

4.ImiGangatho yokuVelisa

Ngokwembono yomgaqo, ivalve yebhola etywiniweyo kunye nevalve yebhola etywiniweyo iyafana, kodwa ngenxa yokuba isitywina phakathi kwesinyithi, Ke isihlalo sentsimbi kufuneka siqwalasele ubunzima, kunye neemeko zokusebenza. , yeyiphi indlela yokusebenza, njl njl. Ukunyangwa kokuqina ngokuqhelekileyo kufunwa yi-valve yesihlalo sentsimbi, kunye nokugaya okuqhubekayo phakathi kwebhola kunye nesihlalo se-valve kuyadingeka ukufezekisa ukutywinwa.Umjikelo wemveliso yentsimbi isihlalo iivalvu zebhola elide, kwaye processing inzima noko, kwaye akukho lula ukwenza metal isihlalo iivalve ibhola kakuhle.

5.UKhetho lweZixhobo

Ukukhethwa kweevalvu zebhola ezithambileyo okanye zentsimbi zisekelwe ikakhulu kwinkqubo ephakathi, ubushushu kunye noxinzelelo.Ngokubanzi, i-medium iqulethe amasuntswana aqinileyo okanye igugile okanye iqondo lobushushu lingaphezulu kwama-degrees angama-200, kwaye ivalve yentsimbi yesitywina sentsimbi ikhethiwe.Ukuba i-diameter ingaphezulu kwama-50, umahluko woxinzelelo lwevalve mkhulu, kwaye i-torque inkulu,Ivalve yesihlalo sentsimbi iyaqwalaselwa.kunye nenqanaba lokutywina kwayo linokufikelela kwinqanaba lesi-6 kungakhathaliseki ukuba ivalve yesihlalo esithambileyo kunye nentsimbi yesitulo sebhola .

RXVALsebenza kwisisombululo sevalvu iminyaka emininzi, ukuba kukho amathandabuzo, Nceda uzive ukhululekile ukuqhagamshelana nayeRXVALiqela .
