IValve yeBhola yaseTshayina: uMgangatho oMtsha kwiTekhnoloji yeValve

Ehlabathini leevalve, iivalve zebhola ziphakathi kwezona ntlobo zidumileyo kunye neziguquguqukayo zeevalvu ezisetyenziswa kumashishini ahlukeneyo. Ngokwakhiwa kwabo okulula kunye nokusebenza okuthembekileyo, iivalve zebhola zisetyenziswa ngokubanzi kwizicelo apho ukugcinwa okuphantsi kunye nokuqina kubalulekile. Iivalvu zebhola zinendlela emile okwebhola elawula ukuhamba kolwelo okanye igesi kumzimba wevalvu. Ibhola ijikeleza ngaphakathi kumzimba wevalvu, ivumela ulwelo okanye igesi ukuba ihambe kwivalve okanye iyeke ukuphuma xa ivalve ivaliwe.

Kwiminyaka yakutshanje, iChina iye yavela njengomdlali ophambili kwishishini levalve yebhola. Abavelisi baseTshayina bavelisa izivalo zebhola ezikumgangatho ophezulu ngamaxabiso akhuphisanayo, kwaye ngokukhawuleza bafumana isabelo semakethi kwimarike yevalvu yehlabathi. Esinye sezizathu zempumelelo yaseTshayina kushishino lwevalvu yebhola kukukwazi ukwenza ukuveliswa kwelizwe kunye nabasebenzi abanezakhono, nto leyo ebenza bakwazi ukuvelisa izivalo zebhola ezichanekileyo nezikumgangatho ophezulu.

Iivalvu zebhola zaseTshayina ngoku zijongwa njengomgangatho omtsha kubuchwepheshe bevalufa, kwaye zisetyenziswa kakhulu kumashishini ahlukeneyo afana neoyile negesi, imichiza, ukuvelisa amandla, unyango lwamanzi, kunye nokuveliswa kwemizi-mveliso. Ziya zithandwa kakhulu ngenxa yokusebenza kwazo okuphezulu, ukugcinwa okuphantsi, kunye nezisombululo ezingabizi kakhulu. Izivalo zebhola zaseTshayina zifumaneka kwizinto ezahlukeneyo ezifana nentsimbi engatyiwayo, ubhedu, intsimbi yekhabhoni, kunye neplastiki. Oku kwenza ukuba abavelisi bavelise uluhlu olubanzi lweevalvu zebhola ezinokuhlangabezana neemfuno zezicelo ezahlukeneyo.

Enye yeenzuzo eziphambili zeevalvu zebhola zaseTshayina kukuguquguquka kwazo. Zingasetyenziselwa zombini uxinzelelo oluphezulu kunye nezicelo eziphantsi, kwaye zifanelekile zombini ukuhamba kwamanzi kunye negesi. Kananjalo banoluhlu olubanzi lobushushu kunye noxinzelelo lwemilinganiselo, ebenza ukuba balungele ukusetyenziswa kwiindawo ezinzima. Ukongeza, iivalvu zebhola zaseTshayina zenzelwe ukujongana noluhlu olubanzi lwamanzi, okwenza ukuba zilungele ukusetyenziswa kumashishini amachiza kunye namayeza.

Enye inzuzo yeevalvu zebhola zaseTshayina ziimfuno zabo zokugcinwa okuphantsi. Ngokungafaniyo nezinye iintlobo zeevalvu, iivalve zebhola zineendawo ezimbalwa ezihambayo, okuthetha ukuba azifane zinxibe kwaye zikrazule. Oku, kwakhona, kunciphisa iindleko zokugcina kunye nokwandisa ubomi bevalve. Ngaphezu koko, iivalvu zebhola zaseChina kulula ukuzifaka nokusebenza, kwaye zinoyilo olulula olubenza kube lula ukucoca nokugcina.

Ukuqukumbela, iivalvu zebhola zaseTshayina zikumgangatho omtsha kubuchwepheshe bevalufa. Ziyonga iindleko, zihlala ixesha elide, ziguquguquka, kwaye zifuna ukulungiswa okuphantsi. Ngobuchule babo bokuvelisa obuphambili kunye nabasebenzi abanezakhono, abavelisi baseTshayina bakhawuleza ukufumana isabelo sentengiso kwimarike yeevalvu zehlabathi. Njengoko imfuno yeevalvu ezisebenzayo nezithembekileyo zikhula, iivalve zebhola zaseTshayina ziqinisekile ukuba zidlala indima ebalulekileyo ekubumbeni ikamva loshishino lwevalvu. Nokuba ukwi-oyile negesi, ikhemikhali, ukuvelisa amandla, okanye nakweliphi na elinye ishishini, iivalvu zebhola zaseTshayina sisisombululo esigqibeleleyo kwiimfuno zakho zevalvu.
