Indima Yomzimba We-Valve Ohlelweni Lokulawula Izimboni kanye Nokucatshangelwa Kokukhetha

Umzimba wevalvu uyingxenye eyisisekelo kakhulu futhi enganakwa kalula yevalvu. Isakhiwo sibonakala silula, empeleni, kusukela endleleni yokuphonsa, ukukhethwa kwezinto kuya ekunembileni kobukhulu, konke kunquma ukuthi ivalvu ingasebenza isikhathi eside ngaphandle kokuvuza, ngaphandle kokuguquka.

Sibone izinkinga eziningi zamavalvu ensimini ebusweni bezingxenye zangaphakathi ezigugile, empeleni, imbangela eyinhloko akwanele ukuqina komzimba wevalvu, noma ukujiya kodonga okungalingani kwesikhala sangaphakathi okuholela ekugxilweni kokucindezeleka. Ikakhulukazi uma kwenzeka umehluko omkhulu wokucindezela noma ukushintshashintsha kwemvamisa ephezulu, umzimba wevalvu awuzinzile ngaphansi kwengcindezi, futhi kwenzeka ukuguquguquka okuncane ngemva kwesikhathi eside, okuholela ekugugeni kwe-spool bias, ukungalungi kahle komugqa wokuvala, bese kuvuza noma kume.

Kukhona futhi inkinga yangempela ukuthi abakhiqizi abaningi ukuze bonge izindleko, ezimweni ezingezona ezijwayelekile besebenzisa ngqo umzimba we-valve yokukhiqiza isikhunta endala, umphumela uba ukuthi i-flange ayivunyelwe ukubhekana nayo, isikhala se-valve cavity asanele, umhlangano wesihlalo se-valve awukho endaweni kanye nenqwaba yezingozi ezifihliwe, futhi ekugcineni ungathembela kuphela ekushiseni nasekugayeni endaweni, 'ukwenza isinxephezelo sokufakwa'. Lokhu esitshalweni sikagesi, imboni yamakhemikhali ayivumeli uhlelo lokungasebenzi isikhathi eside, kuyingozi enkulu kakhulu efihliwe.

Kusukela ezintweni ezibonakalayo, i-WCB evamile, i-CF8, i-CF8M, i-2205 duplex steel, i-316, i-304, ngisho ne-F51, njll., ukukhetha izinto ezingalungile akulula nje kuphela ukugqwala yi-medium, kodwa futhi nasezindaweni ezishisayo nezibandayo zokushaqeka noma ukwehluleka kokucindezeleka. Sake sabona kuphrojekthi ye-chlor-alkali, umzimba we-valve owenziwe nge-CF8M osebenza isigamu sonyaka umgodi wangaphakathi ubelokhu ugqwala, futhi kamuva kwaqinisekisa ukuthi ipayipi elinama-ion e-chlorine ekugxilweni komswakama liphakeme kakhulu kunenani lomklamo.

Ngokwesakhiwo, umzimba wevalvu akufanele nje kuphela ucindezeleke, izinga lokushisa, kodwa futhi uhambisane nendlela yokufaka yangaphakathi. Isibonelo, umzimba wevalvu yebhola udinga ukuba nobukhulu obanele bodonga ukusekela ukucindezelwa kwe-axial, umzimba wevalvu yebhabhathane kufanele ucabangele isikhala sokugoqa indandatho yokuvala, umzimba wevalvu yesango kufanele ulawule ukunemba kokuqondisa kwepuleti yesango, lokhu akuyona nje imidwebo embalwa engahleliwe engaxazululwa.

I-One Lime Machinery iqoqe ulwazi oluningi lwephrojekthi ekukhiqizeni umzimba wama-valve, ihlanganisa kusukela kuma-valve amancane ezinsimbi kuya emizimbeni yama-valve ebhola esindayo angu-24 intshi, isekela ukuphonswa ngokunemba, ukulawula ukujiya kwegobolondo, ukuqhumisa isihlabathi ebusweni kanye nokuhlolwa okungabhubhisi imigodi yama-valve. Sinikeza izinketho eziningi zezinto ezifana ne-CF8M, i-WCB, i-2205, njll., futhi sisekela ukuguqulwa okwenziwe ngokwezifiso kanye ne-prototyping ngokuya ngesakhiwo esisekelayo sekhasimende.

Ekuphetheni, nakuba umzimba we-valve ungeyona ingxenye ebiza kakhulu, kodwa isethi yonke yama-valve 'angathwala' umongo. Kunconywa ukuthi abasebenzi bokuklama nokuthengwa kobunjiniyela, ekuqaleni kwephrojekthi ukuze bacacise imingcele yomzimba we-valve, amafomu okuxhuma kanye nezidingo zesakhiwo se-cavity, bangalindi kuze kube yilapho ukuhlanganiswa noma ukuhlolwa kwengcindezi kuphela ukuze bathole ukuthi 'akukwazi ukufakwa' noma 'phezulu'.
