Ivalve isetyenziselwa ukuvula nokuvala umbhobho, ukulawula indlela yokuhamba, ukulungelelanisa nokulawula iiparitha zendlela yokuhambisa (ubushushu, uxinzelelo kunye nokuhamba) izixhobo zombhobho.Ngokomsebenzi wayo, inokwahlulwa ibe yivalve yokuvala, ivalve yokukhangela, ivalve yokulawula, njl.

Ivalve yinxalenye yolawulo kwinkqubo yokuhambisa ulwelo, enemisebenzi yokunqunyulwa, ukulawulwa, ukuphambukisa, uthintelo oluphikisanayo, ukuqina koxinzelelo, ukuphambuka okanye ukukhululeka kokuphuphumayo, njl njl. ezo zisetyenziswa kwezona nkqubo zinzima zokuzenzela.

Iivalvu zingasetyenziselwa ukulawula ukuhamba komoya, amanzi, umphunga, imidiya edliwayo, udaka, i-oyile, isinyithi esilulwelo kunye nemithombo yeendaba ene-radioactive kunye nezinye iintlobo zolwelo.Iivalvu ngokwezinto eziphathekayo zikwahlulwe zibe zivalvu zentsimbi, iivalve zentsimbi, iivalve zentsimbi engenasici (201, 304, 316, njl.), chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, izigaba ezimbini zentsimbi, iivalvu zeplastiki. , iivalvu ezingezizo eziqhelekileyo.

I-valve ikwinkqubo yolwelo, esetyenziselwa ukulawula ulwalathiso lolwelo, uxinzelelo, ukuhamba kwesixhobo, kukwenza umbhobho kunye nezixhobo phakathi (ulwelo, igesi, umgubo) ukuhamba okanye ukumisa nokulawula ukuhamba kwesixhobo. .

Ivalve yinxalenye yolawulo lwenkqubo yokuhambisa ulwelo lwemibhobho, esetyenziselwa ukutshintsha icandelo lokuhamba kunye nesalathiso sokuhamba okuphakathi, kunye ne-diversion, cut-off, throttle, check, diversion okanye i-overflow yokunciphisa imisebenzi yokunciphisa uxinzelelo.Ivalve esetyenziselwa ukulawula ulwelo, ukusuka kweyona valve ilula yeglowubhu ukuya kwinkqubo yolawulo oluzenzekelayo entsonkothileyo esetyenziswa kwiintlobo ngeentlobo zeevalvu, ezahlukeneyo kunye neenkcukacha, ubungakanani begama levalve ukusuka kwivalve yesixhobo encinci ukuya kubungakanani bombhobho weshishini. ivalve ukuya kwi-10m.Ingasetyenziselwa ukulawula amanzi, umphunga, ioyile, irhasi, udaka, iintlobo ngeentlobo zemithombo yeendaba ezityiwayo, isinyithi esilulwelo kunye nolwelo lweradioactive kunye nolunye uhlobo lokuhamba kwamanzi, uxinzelelo olusebenzayo lwevalve lunokusuka kwi-0.0013MPa ukuya kwi-1000MPa ye-ultra-high. Uxinzelelo, ubushushu bokusebenza bunokuba yi-C-270 ℃ yobushushu obuphantsi kakhulu ukuya kwi-1430 ℃ yobushushu obuphezulu.

I-valve inokulawulwa ngeendlela ezahlukeneyo zokuhambisa, ezifana ne-manual, umbane, i-hydraulic, i-pneumatic, i-turbine, i-electromagnetic, i-electromagnetic, i-electro-hydraulic, i-electro-hydraulic, i-gas-hydraulic, i-spur gear, i-bevel gear drive;Kuxinzelelo, ubushushu okanye enye ifom phantsi kwentshukumo yemiqondiso yesivamvo, isenzo, ngokwemfuno yogcino okanye ayixhomekeke kwimiqondiso yoluvo lokuvula okanye ukuvala lula, ukuxhomekeka kwi-drive okanye kwi-othomathikhi ye-othomathikhi eyenza ukuvula nokuvala ivalve ukuphakamisa, ukutyibilika, indawo okanye intshukumo ejikelezayo, ukuze utshintshe ubungakanani bezibuko ukuze uqonde umsebenzi wolawulo.
