Uhlalutyo olunzulu lweenkcukacha kunye nokusebenza kweevalvu zeglowubhu zeflange zaseTshayina
Kwiinkqubo zemibhobho yemizi-mveliso, iivalvu zeglowubhu zidlala indima ebalulekileyo njengoko zisebenza njengabagcini-masango abangqongqo, belawula ukuhamba kolwelo. Phakathi kweentlobo ezininzi zeevalvu zeglowubhu, ivalve yeglowubhu yeglowubhu yaseTshayina ibalasele ngokugqwesa kwayo yonke imisebenzi kunye nokuthembeka. Namhlanje, siza kutyhila isigqubuthelo sayo esingaqondakaliyo kwaye siphonononge iinkcukacha kunye nokusebenza kwayo ngokweenkcukacha.
Ivalve yeglowubhu yomgangatho waseTshayina, njengoko negama lisitsho, yivalve yeglowubhu eyilwe yaze yenziwa ngokwemigangatho yelizwe, eqhagamshelwe kwinkqubo yemibhobho ngoqhagamshelo lweflange. Olu hlobo lwevalve luyilwe ngokugqwesileyo kwaye lunokuvulwa okanye luvalwe ngokusebenza kwesiqu sokuphakamisa ngaphandle kokutshintsha indlela yokuhamba kwamanzi. Ulwakhiwo lwayo ludla ngokubandakanya amacandelo afana nomzimba wevalvu, isigqubuthelo sevalvu, idiskhi yevalvu, isiqu sevalvu, ikhonkco lokutywina, njl. njl., nganye kuzo idlala indima ebaluleke kakhulu.
Ngokubhekiselele kwiinkcukacha, iivalve zeglowubhu ezisemgangathweni zaseTshayina zilandela imigangatho efanelekileyo efana ne-GB/T12235, enoluhlu olubanzi lweediameter ukusuka kwiimilimitha ezimbalwa ukuya kwiimilimitha ezilikhulu, ezinokuhlangabezana neemfuno zemibhobho yobukhulu obahlukeneyo. Umzekelo, ivalve yeglowubhu eqhelekileyo inokuba nedayamitha ye-DN50, okuthetha ukuba inokudibana ngaphandle komthungo namanye amacandelo emibhobho ye-DN50. Ukongezelela, ngokweengcinezelo ezahlukeneyo zokusebenza, iivalve zeglowubhu zikwahlulahlulwe ngamanqanaba ahlukeneyo oxinzelelo, njenge-1.6MPa, 2.5MPa, 4.0MPa, njl., ukuhlangabezana neemfuno zeemeko ezahlukeneyo zokusebenza.
Ngokubhekiselele ekusebenzeni, iimpawu zemigangatho yeglowubhu yeflange yaseTshayina inokushwankathelwa "njengokuchaneka, ukuzinza, kunye nokuqina". Okokuqala, ukuchaneka kubonakala kumandla ayo okubonelela ngolawulo oluchanekileyo lokuhamba. Njengompheki onamava okwaziyo ubushushu, ivalve yeglowubhu inokulawula ngokuchanekileyo umyinge wokuhamba kunye nesantya sokuhamba kolwelo ngokulungelelanisa ukuvulwa kwayo. Okwesibini, uzinzo lubonakaliswa ekusebenzeni kwayo okugqwesileyo kokutywinwa. Nokuba kuxinzelelo oluphezulu okanye kwindawo ezinoxinzelelo oluphantsi, iivalvu zeglowubhu zinokugcina ukutywinwa kakuhle kwaye zithintele ukuvuza, ngenxa yolwakhiwo lokutywina oluyilwe ngononophelo kunye nezixhobo zokutywina ezikumgangatho ophezulu. Ekugqibeleni, ukuqina kuqinisekiswa ngokukhethwa kwezinto ezinganyangekiyo kunye ne-corrosion-resistant-resistant, kunye neendawo ezichanekileyo zoomatshini, ukuqinisekisa ukuthembeka kwevalve yeglobhu ekusebenziseni ixesha elide.
Kusetyenziso olusebenzayo, okuluncedo kwiivalvu zeglowubhu zeflange ezisemgangathweni zaseTshayina zibonakala ngakumbi. Ukuthatha isityalo sekhemikhali njengomzekelo, kufuna ukutshintshwa rhoqo kokuhamba kwamanzi ngexesha lenkqubo yokuvelisa, enokuthi iphunyezwe ngokulula ngokusebenzisa i-valve yeglobhu yohlobo lwe-flange. Ngaphezu koko, xa ukugcinwa kwezixhobo okanye ukutshintshwa kuyadingeka, umsebenzi wokuvala i-valve yokuvala unokuqinisekisa ukusebenza kakuhle ngaphandle kokukhathazeka ngokuvuza kwamanzi.
Ngokuqinisekileyo, ukukhetha ivalve efanelekileyo yokuvala ifuna izakhono ezithile. Ngokomzekelo, kwiindawo eziphakamileyo zokushisa kunye noxinzelelo oluphezulu, kuyimfuneko ukukhetha izinto ezichasene nokushisa okuphezulu kunye noxinzelelo; Kwimithombo yeendaba eyingozi kakhulu, kuyafuneka ukuba ukhethe izinto ezinganyangekiyo kwi-corrosion. Zonke ezi zifuna uqwalaselo olululo olusekwe kwiimeko zokwenyani zokusebenza.
Isishwankathelo, iivalvu zeglowubhu zeflange ezisemgangathweni zaseTshayina ziye zayinto eyimfuneko kwiinkqubo zemibhobho yeshishini ngenxa yeenkcukacha zazo ezahlukeneyo kunye nokusebenza okuzinzileyo. Ulawulo lwayo oluchanekileyo, ukutywinwa okugqwesileyo, kunye nokuqina kuyenza isebenze ngokugqwesileyo kwiindawo ezahlukeneyo ezintsonkothileyo. Ukuqonda iinkcukacha kunye nokusebenza kwayo kubaluleke kakhulu ekuqinisekiseni ukhuseleko kunye nokusebenza kakuhle kwemveliso yemizi-mveliso.
