1. Kupanga Mpando Wapadera
Vavu yoyandama ya mpira imatengera kapangidwe ka mphete yosindikizira yosinthika. Pamene kuthamanga kwapakati kumakhala kochepa, malo okhudzana ndi mphete yosindikizira ndi mpira amakhala ochepa. kotero apamwamba kusindikiza chiŵerengero aumbike pamalo pamene mphete chisindikizo ndi mpira kukhudzana kuonetsetsa odalirika kusindikiza. Kuthamanga kwapakati kukakwera, malo olumikizirana ndi chisindikizo ndi mpira amakulirakulira limodzi ndi kupindika kwa mphete yosindikizira, kotero mphete yosindikizira imatha kupirira kukankhidwa kwapakatikati popanda kuonongeka.
2. Kapangidwe Kapangidwe ka Moto
Pakayaka moto pakugwiritsa ntchito valavu, mphete yapampando yopangidwa ndi PTFE kapena zinthu zina zopanda zitsulo zidzawonongeka kapena kuonongeka pansi pa kutentha kwakukulu ndikuyambitsa kutsika kwakukulu. Mphete yosindikizira yamoto imayikidwa pakati pa mpira ndi mpando kotero kuti mpando wa valve ukawotchedwa, sing'angayo imakankhira mpirawo mofulumira kumphepete mwachitsulo chosindikizira chachitsulo kuti apange chitsulo chothandizira kuzitsulo zosindikizira zachitsulo, zomwe zingathe kulamulira bwino kutayikira kwa valve. Komanso, pakati flange kusindikiza gasket amapangidwa ndi zitsulo bala gasket, amene angathe kuonetsetsa kusindikiza ngakhale kutentha kwambiri. Mapangidwe amagetsi osayaka moto a valve yoyandama amagwirizana ndi zofunikira mu API 607, spi 6FA, BS 6755 ndi miyezo ina.
3. Kusindikiza kodalirika kwa Vavu tsinde
Tsinde limaperekedwa ndi phewa pansi pake kotero kuti silidzawombedwa ndi sing'anga ngakhale pansi pa zovuta kwambiri monga kuthamanga kwachilendo kukwera mkati mwa valavu ya valve, kulephera kwa mbale ya gland ndi etc. Komanso, kupewa kutayikira pambuyo pake. kunyamula kwa tsinde kumatenthedwa ngati moto, kukakamiza kumayikidwa pamalo pomwe tsinde la phewa ndi kukhudzana kwa thupi kuti apange mpando wosindikiza mobwerera. Mphamvu yosindikiza ya chisindikizo cham'mbuyo idzawonjezeka molingana ndi kuchuluka kwa kuthamanga kwapakati, kuti zitsimikizire kusindikizidwa kwa tsinde modalirika pansi pa zovuta zosiyanasiyana, kuteteza kutayikira ndikupewa kufalikira kwa ngozi.
Tsinde limatenga mawonekedwe osindikizira a mtundu wa V. Kuyika kwa mtundu wa V kumatha kusintha mphamvu yokakamiza ndi mphamvu yapakatikati ya gland kukhala mphamvu yosindikiza ya tsinde.
Malinga ndi zomwe wogwiritsa ntchito amafuna, makina osindikizira a disc odzaza amatha kutengedwa kuti apangitse kusindikiza kwa tsinde kukhala kodalirika.
4. Anti-static Structure
Vavu ya mpira imaperekedwa ndi anti-static structure ndipo imatenga chipangizo chotulutsa magetsi chokhazikika kuti chipangitse mwachindunji njira yokhazikika pakati pa mpira ndi thupi kapena kupanga njira yokhazikika pakati pa mpira ndi thupi kudzera pa tsinde, kuti itulutse magetsi osasunthika opangidwa. chifukwa cha kukangana pakutsegula ndi kutseka kwa mpira ndi mpando kudzera mu payipi, kupewa moto kapena kuphulika komwe kungayambike chifukwa cha static spark ndikuwonetsetsa chitetezo chadongosolo.
5. Lock And Misoperation Kupewa
Valve yamanja ya mpira imatha kutsekedwa ndi loko ikakhala pamalo otseguka kapena otseka. Chidutswa cha 90 ° chotseguka ndi chotseka chokhala ndi dzenje lokhoma chimapangidwa kuti chipewe kusokonezeka kwa ma valve chifukwa chogwira ntchito ndi osagwiritsa ntchito, komanso kutha kuteteza kutseguka kapena kutseka kwa valve, kapena ngozi zina zomwe zimachitika chifukwa cha kugwedezeka kwa mapaipi kapena zinthu zosayembekezereka. Ndizothandiza kwambiri makamaka pazinthu zoyaka moto. Ndizothandiza kwambiri makamaka pakuyaka ndi kuphulika kwamafuta, mapaipi opangira mankhwala ndi zamankhwala kapena machubu akumunda. Mbali pamutu wa tsinde kuti anaika ndi chogwirira utengera lathyathyathya kapangidwe. Pamene valavu yatsegulidwa, chogwiriracho chimakhala chofanana ndi payipi, kotero kuti zizindikiro zotsegula ndi zotseka za valve zitsimikizidwe kuti palibe cholakwika.
Zida za Newsway Valves
Thupi la valve ya NSW ndi zinthu zochepetsera zitha kuperekedwa mumtundu wa Forged ndi mtundu wa Casting. Pafupi ndi zinthu zosapanga dzimbiri ndi zitsulo za kaboni, timapanganso ma valve muzinthu zapadera monga titaniyamu, ma aloyi a faifi tambala, HASTELLOY®*, INCOLOY®, MONEL®, Alloy 20, super-duplex, corrosion resistant alloys ndi urea grade grade.
