Ulwakhiwo lwebhokisi yokuzalisa kwiqondo lobushushu eliphezulu kunye neemeko zoxinzelelo oluphezulu lweengxaki zokutywina kunye neengcinga zokuphucula
Kwisakhiwo seevalvu zebhola kunye neevalvu zesango, ibhokisi yokuzalisa njengeyona nto iphambili kwinkqubo yokutywina isiqu, nangona isakhiwo sayo singashukumiyo, kodwa ngokuthe ngqo yenza umsebenzi obalulekileyo wokuthintela ukuvuza kwemidiya. Ingakumbi kubushushu obuphezulu kunye noxinzelelo oluphezulu, iimeko zokuvula nokuvala rhoqo, amandla olwakhiwo lwebhokisi yokuzalisa, ukunyamezelana kokulingana kunye nokusebenza kokupakisha kunye kugqiba ubomi kunye nokuzinza kwenkqubo yokutywina yonke.
Kwiminyaka yakutshanje, sifumanise kwiiprojekthi ezininzi zamachiza kunye namandla ukuba iingxaki zokutywina iibhokisi zokupakisha ziye zaba yindawo yokusilela ephezulu. Ingxelo yomsebenzisi: inani leevalvu zebhola ezinoxinzelelo oluphakathi ekusebenzeni kwesiqingatha sonyaka emva kokuvuza kweengcambu zesiqu, uhlalutyo olongezelelweyo lubonisa ukuba amandla okupakisha awalingani nto leyo ebangela ucinezelo olungaphelelanga, kwaye umngxuma wangaphakathi webhokisi yokuzalisa kukho ukuphambuka kwe-coaxial kunye nobunzima bengxaki yokungabikho kokwaneleyo.
Kule meko yokusebenza, sicebisa ukuba ulwakhiwo lwebhokisi yokupakisha lulungele uyilo loxinzelelo olulinganayo, kwaye umngxuma wangaphakathi kufuneka ugqunywe ngokwahlukeneyo ukuze kulawulwe uburhabaxa bodonga lwangaphakathi ngaphakathi kweRa 0.8 kunye ne-coaxiality ingabi ngaphezu kwe-0.02 mm. Ukongeza, ukwanda kwesakhiwo esikhokelayo okanye uyilo lwamagxa oluthintelayo kuya kunceda uxinano lokupakisha ngokulinganayo kunye nokusebenza kwe-valve stem okuzinzileyo.
Ngokuphathelele ukhetho lwezinto, sihlala sicebisa ukusetyenziswa kwentsimbi engagqwaliyo efana ne-AISI 316 okanye i-F6a ukuze ivumelane neendlela ezahlukeneyo zokubola. Umxube wokupakisha ucetyiswa ukuba ube yiringi ye-PTFE eguquguqukayo ye-graphite composite okanye i-graphite washer ene-metal-coated washer, enokumelana nokutywina okungcono kunye nokumelana nokuguga phantsi kobushushu obuphezulu.
Ngexesha lokwenziwa kwemishini, ukulingana kwebhokisi yokuzalisa kunye ne-gland, umkhono ongaphezulu kunye nezinye iindawo ezinxulumene nayo kufuneka kuhlolwe ngokupheleleyo, kungekhona ngokwahlukeneyo. Sicebisa ukuba ubudlelwane bokudibana buphawulwe ngokulinganayo kwinqanaba lokuzoba okanye buqhagamshelwe yimodeli yethu ukuqinisekisa ukuba umsantsa wokuhlanganisa ufanelekile kwaye ukubethelwa koxinzelelo lwetywina kuchanekile. Uyilo olupheleleyo lwesakhiwo kufuneka luqwalasele i-torque yokuvula neyokuvala, uxinzelelo lokupakisha kunye nokwandiswa kobushushu, ukuze kuphuculwe ngokwenene ukusebenza kokutywina kwevalvu.
