Lub zog foob ntawm lub pob valve yog lub foob ntawm cov hlau thiab hlau, thiab lub foob pob thiab lub rooj zaum valve yog ob qho tib si hlau. Machining raug thiab craftsmanship yog qhov nyuaj dua, feem ntau yog siv nyob rau hauv qhov kub thiab txias los yog siab siab, haum rau hais nrog cov xov xwm. Lub foob mos yog lub foob ntawm cov hlau thiab tsis yog hlau, xws li nylon \ tetrafluoroethylene, thiab cov qauv kev tsim khoom yog tib yam.
Lub mos thiab tawv foob yog rau cov khoom sib khi ntawm lub rooj zaum valve. Lub zog foob yog qhov ua tiav nrog cov khoom siv lub rooj zaum kom ntseeg tau qhov tseeb ntawm kev sib txuam nrog lub valve core (pob). Feem ntau, muaj cov hlau tsis muaj steel, hlau alloy, thiab tawv alloy. Lub foob mos txhais tau hais tias cov khoom sib khi uas tau muab tso rau hauv lub rooj zaum valve yog cov khoom tsis yog xim hlau. Vim tias cov khoom siv mos sealing muaj qee qhov kev sib tw ntawm elasticity, qhov kev ua tiav qhov yuav tsum tau muaj tsawg heev rau lub zog foob.
Vim tias qhov chaw ua haujlwm nyuaj hauv ntau cov tshuaj thiab cov khoom siv kho tshuab, ntau yam ntawm lawv yog qhov kub thiab txias, kev sib txhuam tsis kam ntawm qhov nruab nrab yog qhov loj, thiab corrosiveness muaj zog. Tam sim no hais tias cov cuab yeej siv tau zoo dua, kev siv ntau yam ntaub ntawv zoo dua, thiab kev ua tiav tuaj yeem ua raws. Tam sim no, lub zog foob pob valve tau nthuav dav dav.Qhov tseeb, lub hauv paus ntsiab lus ntawm lub foob pob valve yog tib yam li cov foob mos, tab sis vim nws yog lub foob ntawm cov hlau, nws yog ib qho tsim nyog yuav tsum xav txog qhov hardness kev sib raug zoo ntawm cov hlau. , nrog rau kev ua haujlwm, thiab qhov nruab nrab siv li cas. Feem ntau, kev kho hardening yog yuav tsum tau, thiab kev sib tsoo txuas ntxiv ntawm lub pob thiab lub rooj zaum valve yuav tsum ua kom tiav lub foob. Hard-sealed pob li qub muaj lub voj voog ntev ntau lawm thiab kev ua haujlwm nyuaj, yog li tus nqi ntawm cov pob valve nyuaj yog ntau dua.
Lub foob mos tuaj yeem ua tiav qib siab ntawm kev sib khi, thaum lub foob tawv tawv tuaj yeem siab lossis qis raws li qhov yuav tsum tau ua; cov foob mos muag yuav tsum yog fireproof, vim hais tias ntawm qhov kub thiab txias, cov khoom ntawm cov mos mos foob yuav xau, thaum lub foob tawv tawv tsis muaj qhov teeb meem no; Feem ntau, nws tuaj yeem ua tiav ntawm qhov siab heev, tab sis lub foob mos tsis yog. Lub foob tsis tuaj yeem siv rau qee qhov xwm txheej (xws li qee qhov xov xwm corrosive) vim qhov teeb meem ntawm qhov nruab nrab ntws. Raws li kev tsim khoom, muaj qhov sib txawv me ntsis ntawm ob, feem ntau qhov sib txawv ntawm lub rooj zaum valve, lub foob mos yog tsis yog xim hlau, thiab lub foob tawv tawv yog xim hlau.
Kev xaiv ntawm cov mos mos thiab tawv kaw pob li qub feem ntau yog nyob ntawm cov txheej txheem nruab nrab, kub thiab siab. Feem ntau, qhov nruab nrab muaj cov khoom siv los yog muaj kev puas tsuaj lossis qhov kub siab tshaj 200 degrees. Nws yog qhov zoo dua los siv cov ntsaws ruaj ruaj. Lub valve nrog ib txoj kab uas hla ntau dua 50 muaj qhov sib txawv loj dua thiab tseem txiav txim siab qhov qhib torque ntawm lub valve. Thaum lub torque loj, qhov ruaj khov pob valve yuav tsum raug xaiv, thiab nws qib sealing tuaj yeem ncav cuag 6 qib tsis hais qhov muag muag lossis tawv foob.
