1. I-valve ithatha isakhiwo esiqondile.
2. Ukuze ugweme ukushayelwa kwesivinini esiphezulu se-medium se-sealing pair ngesikhathi sokusetshenziswa, i-sealing degree ithatha isakhiwo sesihlalo se-valve ephindwe kabili, i-throttling yokuqala futhi ivimbe izimpahla ezintshontshiwe, nokusebenzisa i-throttling medium ukwenza indawo yokuvala izihlanzeke, ngaleyo ndlela ixazulule ngokuphelele. ukuvuza kanye nempilo yesevisi emfushane.
3. Ukuxhumana phakathi komzimba nebhonethi yevalvu yeglobu evimbela ukubhoboza enobubanzi obungu-DN≤50mm wuxhumo lwe-clamp pin shaft, futhi ukuxhumana phakathi komzimba nebhonethi yevalvu yembulunga evimbela ukubhoboza ngaphezu kwe-DN65 kuwukuxhuma kwe-flange okuzivalayo. ifomu. Zombili lezi zakhiwo ezimbili kulula ukuziqaqa, ukuhlanganisa, ziphephile futhi zithembekile.
4. Amapayipi egatsha emikhawulweni yomibili ye-valve axhunywe nge-welding.
5. Isihlalo se-valve ne-valve disc sealing surface zenziwe nge-cobalt-based hard alloy overfacing. Indawo yokuvala inezici zokuqina okuphezulu, ukumelana nokuhuzuka kanye nokumelana nokuhuzuka.
6. Insimbi ene-nitrided isetshenziswa njenge-stem material ukwenza ubuso besiqu ngemva kwe-nitriding ibe nobulukhuni obukhulu, ukumelana nokugqoka, ukumelana nokuklwebheka, ukumelana nokugqwala kanye nempilo ende yesevisi.
