Ivalvu yebhola engaqhumiyo ngomoya

I umoya  ayivumeli ukuqhuma Ivalvu yebhola isebenzisa isakhiwo sokufakelwa ngaphezulu, esinciphisa iibholithi zokudibanisa zomzimba wevalvu phantsi koxinzelelo oluphezulu kunye neemeko ezinkulu zobukhulu, siphucula ukuthembeka kwevalvu, kwaye sinokoyisa impembelelo yobunzima benkqubo ekusebenzeni kwevalvu eqhelekileyo.
Iiparameter zeMveliso:
Imodeli:
Izixhobo: DN15-500
Ubukhulu: WCB, CF8, CF8M, CF3M
1. Isishwankathelo seMveliso yePneumatic ayivumeli ukuqhuma Ivalvu yeBhola
Ivalvu yebhola engaqhumiyo ngomoya iqulathe uthotho lwe-AT(GT) isixhobo somoyakunye nevalvu yebhola edadayo, efanelekileyo kwiindlela zokulawula kunye nokucima. Isebenza kakuhle kakhulu ekutywineni, umthamo wokuhamba kwamanzi aphezulu, isakhiwo esilula, ubomi benkonzo ende, kunye nokugcinwa okulula. I-actuator ehamba nayo inesakhiwo esilula nesincinci esine-torque enkulu yokukhupha. Xa ixhotyiswe ngeeswitshi zokuhamba ezithintela ukuqhuma, iivalvu ze-solenoid ezithintela ukuqhuma, izinciphisi zoxinzelelo, kunye nombane womoya we-0.4-0.7 MPa, ivalvu yebhola ethintela ukuqhuma ephefumlayo ivumela ukusebenza kokutshintsha kwaye ibonelela ngeepere ezimbini zemiqondiso yoqhagamshelwano engasebenziyo ukubonisa imeko yevalvu. I-actuator ifumaneka kwiimodeli ezisebenza kanye kunye nezisebenza kabini. Inzuzo ye-actuator esebenza kanye kukuba xa kukho ukusilela kumthombo wamandla, i-actuator ethintela ukuqhuma Ivalvu yeBhola yomoya icwangcisa ngokuzenzekelayo iimfuno zenkqubo yolawulo ukuze ivuleke okanye ivale indawo efunekayo. Ivalvu yebhola engaqhumiyo ngomoya isetyenziswa kakhulu kumashishini afana neekhemikhali, ipetroliyam, ilaphu elikhanyayo, umbane, ukutya kunye namayeza, ifriji, i-aerospace, kunye nokwenza iphepha. Ayinakulawula kuphela igesi, ulwelo kunye nemidiya yomphunga kodwa ikwafanelekile nokuphatha izinto ezimdaka kunye nefayibha.
2, Iimpawu zemveliso zevalvu yebhola engaqhumiyo yomoya
(1) Ivalvu yebhola yenye yeentlobo zeevalvu ezinokumelana okuphantsi kolwelo, nokuba kwiivalvu zebhola ezincitshisiweyo, ukumelana kwayo nolwelo kuncinci kakhulu.
(2) Iibheringi zeThrust zinciphisa i-friction torque yesiqu sevalvu, zivumela ukusebenza okulinganiselayo nokuguquguqukayo kwexesha elide kwesiqu sevalvu.
(3) Isihlalo sevalvu sisebenza kakuhle ekutywineni kwaye senziwe ngeeringi zokutywina ezenziwe ngezinto ezifana ne-polytetrafluoroethylene. Ulwakhiwo kulula ukulutywina, kwaye amandla okutywina evalvu yebhola ayanda ngokwanda koxinzelelo oluphakathi.
(4) I-valve stem seal ithembekile. Njengoko i-valve stem ijikeleza kuphela kwaye ingashukumi phezulu okanye ezantsi, i-additive seal ye-valve stem ayonakaliswa lula, kwaye amandla okutywina ayanda ngokunyuka koxinzelelo oluphakathi.
