I-BS 1868 nguMgangatho waseBhritane ochaza iimfuno zeevalvu zokujonga intsimbi okanye iivalvu ezingabuyiyo ezinezihlalo zentsimbi ukuze zisetyenziswe kumashishini afana nepetroleum, i-petrochemical, kunye namashishini adibeneyo.Lo mgangatho ugubungela imilinganiselo, ubushushu boxinzelelo, iimathiriyeli, kunye neemfuno zovavanyo lwevalvu yokujonga ujingi. Kumxholo wevalve yokujonga ujingi eyenziwe ngokuhambelana ne-BS 1868, iya kuyilwa ukuhlangabezana nemilinganiselo ethile kunye nokusebenza okuchazwe umgangatho.Oku kuqinisekisa ukuba i-valve inokuthintela ngokufanelekileyo ukubuyisela umva kwaye ihlangabezana nokhuseleko oluyimfuneko kunye nemigangatho yomgangatho wokusetyenziswa kwayo ekujoliswe kuyo.Ezinye zezinto eziphambili ze-valve yokukhangela i-swing eyenziwe kwimigangatho ye-BS 1868 ingabandakanya isigqubuthelo esiboshiweyo, izihlalo zokuhlala ezihlaziyiweyo, kunye ne-swing. -uhlobo lwediski.Ezi zivalo zisoloko zisetyenziswa kwizicelo zoxinzelelo oluphezulu kunye nobushushu obuphezulu apho ukuthintela ukubuya umva kubalulekile.Ukuba unemibuzo ethile malunga nevalve yokujonga ujingi eyenziwe ngokwemigangatho ye-BS 1868 okanye ufuna iinkcukacha ezithe vetshe malunga neenkcukacha zayo, izixhobo, okanye iimfuno zovavanyo, nceda undazise, kwaye ndingakuvuyela ukuncedisa ngakumbi.
1. Umzimba we-valve kunye nefom yokudibanisa i-valve cover: Iklasi150 ~ I-Class600 usebenzisa isigqubuthelo sevalve yeplagi;I-Class900 ukuya kwiKlasi2500 ithatha isigqubuthelo sevalvu yokutywina ecinezelekileyo.
2. Ukuvula kunye nokuvala iindawo (i-valve disc) uyilo: i-disc yevalve iyilwe njengohlobo lokujingi, inamandla okwaneleyo kunye nokuqina, kunye nomphezulu wokutywina wediski yevalve unokujonga imathiriyeli yegolide yentsimbi okanye imathiriyeli engeyiyo eyentsimbi ngokomsebenzisi. iimfuno.
3. Isigqubuthelo se-valve esiphakathi kwi-gasket yefom yesiqhelo: I-valve yokuhlola i-Class150 isebenzisa i-gasket edibeneyo ye-graphite yensimbi engenasici;C|ass300 itshekhi valve ngentsimbi stainless graphite inxeba gasket;I-valve yokuhlola i-Class600 ingasetyenziselwa ilitye lensimbi engenasici.I-Class900 ukuya kwi-Class2500 yokujonga iivalvu zisebenzisa i-self-pressure yokutywina amakhonkco esinyithi.
5. Ifom yokusebenza: Ivalve yokutshekisha ivula ngokuzenzekelayo okanye ivale ngokwemeko yokuhamba okuphakathi.
6. Uyilo lwe-Rocker: I-rocker inamandla okwaneleyo, inkululeko eyaneleyo yokuvala i-disc ye-valve, kwaye ixhotyiswe ngesixhobo sokunciphisa ukuthintela indawo yokuvula ukuba ibe phezulu kakhulu ukuvala.
7. Uyilo lwendandatho yokuphakamisa: I-valve yokukhangela i-caliber enkulu yenzelwe umsesane wokuphakamisa kunye nesakhelo sokuxhasa, esilungele ukuphakamisa.
Ngethuba lokuvula kunye nokuvala i-valve yeglobhu yentsimbi ekhandiweyo, ngenxa yokuba i-friction phakathi kwe-disc kunye ne-surface yokutywina ye-valve yomzimba incinci kune-valve yesango, ayigugi.
Ukuvula okanye ukuvala i-stroke ye-valve stem ifutshane, kwaye inomsebenzi othembekileyo wokusika, kwaye ngenxa yokuba ukutshintshwa kwe-valve seat port ilingana ne-stroke ye-valve disc, ikulungele kakhulu ukulungiswa. yesantya sokuhamba.Ke ngoko, olu hlobo lwevalve lufanelekile kakhulu ukunqunyulwa okanye ukulawulwa kunye ne-throttling.
