Udinga ivalve eyomeleleyo kuneqhekeza elinye kodwa elingabizi njengeqhekeza lesithathu. Ukukhetha engalunganga kuthetha ukuhlawula ngaphezulu okanye ukufumana ivalve ongenakukwazi ukuyilungisa xa ibalulekile.

Ivalve eneziqwenga ezibini zebhola inamalungu amabini aphambili omzimba ajijwayo, avale ibhola aze atywine ngaphakathi. Olu luyilo lomelele kunevalve eneqhekeza elinye kwaye luvumela ukulungiswa, nangona kufuneka kuqala lususwe kumbhobho.

Ivalve yebhola enamacandelo amabini lihashe lomsebenzi lokwenyani kwihlabathi lemibhobho. Lolunye lwezona ntlobo zixhaphakileyo endixoxa ngazo namaqabane am, anjengoBudi, umphathi wokuthenga e-Indonesia. Abathengi bakhe, abangoonokontraka ngokubanzi kunye nabasasazi, bafuna isisombululo esithembekileyo, esinexabiso elisebenzayo kwimisebenzi yemihla ngemihla. Uyilo olunamacandelo amabini lubetha laa ndawo imnandi ngokugqibeleleyo. Inika uphuculo olubalulekileyo kumandla kunye nokusebenza ngaphezulu kwezona zivalo zisisiseko ngaphandle kweendleko eziphezulu zeemodeli ezintsonkothileyo zamashishini. Ukuqonda ngokwenene ixabiso layo, kufuneka ubone apho ingena khona kumfanekiso omkhulu.

Yintoni ivalve enamacandelo amabini?

Ungawubona umthungo apho umzimba wevalvu udityaniswe khona, kodwa kuthetha ukuthini oko? Ukuqonda ukwakhiwa kwayo ngundoqo ekwazini ukuba lukhetho olufanelekileyo lwempilo yexesha elide yenkqubo yakho.

Ivalve eneziqwenga ezibini inomzimba ophambili kunye neqhekeza lesibini, isidibanisi sokugqibela, esingena kuyo. Olu xhulumaniso lunemisonto lugcina ibhola kunye nezihlalo, okwenza ivalve isebenze kwaye ixhathise ngakumbi kuxinzelelo kunoyilo lwesiqwenga esinye.

Ukwakhiwa kwe-aivalve enamacala amabiniluphawu lwayo oluphambili. Khawucinge ukuba umzimba wevalvu wenziwe kumacandelo amabini. Icandelo elikhulu libambe isiqu kunye nomqheba, ngelixa icandelo elincinci liyikepusi enemisonto. Xa zidityanisiwe kunye, ziyayibambela phantsi kwibhola kunye nezihlalo ezithambileyo (eziqhele ukwenziwa nge-PTFE) ezenza itywina. Olu yilo lomzimba olunemisonto lomelele ngakumbi kunevalve eneqhekeza elinye, apho ibhola ifakwe ngentunjana encinci, ehlala ifuna ibhola encinci (izibuko elincitshisiweyo). Ukwakhiwa kwamacandelo amabini kuvumela ibhola enkulu, "i-port epheleleyo", oku kuthetha ukuba umgodi webhola ulingana nobukhulu obufana nombhobho, okhokelela ekuhambeni okungcono kunye nokulahlekelwa kwengcinezelo encinci. Ukuba itywina lithe laphelelwa, unokukhulula umzimba, ubuyisele amalungu, kwaye uwubuyisele emsebenzini. Ngumhlaba ophakathi kakhulu kubathengi abaninzi beBudi abafuna ivalve eqinile kwaye ilungiseka.

Uthini umahluko phakathi kohlobo loku-1 kunye nohlobo lwesi-2 lwevalve yebhola?

Uva amagama afana no “Uhlobo loku-1” kunye “nohlobo lwama-21” kodwa awuqinisekanga ukuba athetha ukuthini. Ukukhetha ngokusekelwe kula magama ngaphandle kokuwaqonda kunokuthetha ukuphoswa kwiimpawu eziphambili zokhuseleko.

La magama akabhekiseli kulwakhiwo lomzimba (njengeziqwenga ezibini) kodwa kuyilo lwezizukulwana, ngokuqhelekileyo iivalvu zenyani zomanyano. “Uhlobo lwama-21″ sisishunqulelo soshishino kuyilo lwangoku olunokhuseleko olomeleziweyo kunye neempawu ezisebenzisekayo.

Kubaluleke kakhulu ukuba ungabhidanisi isitayile somzimba ngala manani “ohlobo”. Ivalve “embini” ichaza indlela umzimba owakhiwe ngayo ngokwasemzimbeni. Amagama afana no "Uhlobo lwama-21," kwelinye icala, achaza iseti ethile yeempawu zale mihla, kwaye ahlala efumaneka kwiivalvu zenyani zomanyano ezinamaqhekeza amathathu. Kuya kufuneka ndiyicacise le nto kwiqela likaBudi ngamanye amaxesha. Umthengi unokucela i"Uhlobo lwama-21 ivalve enamacandelo amabini,"kodwa ezo mpawu ziyinxalenye yeklasi yevalve eyahlukileyo. Olona phawu lubalulekileyo lohlobo lwama-21 luyiloblock-ekhuselekileyo union nut, okuthintela ukuba ivalve ingavulwa ngengozi kwaye ivuleke ngelixa inkqubo iphantsi koxinzelelo. Olu luphawu olubalulekileyo lokhuseleko. Bakwabandakanya i-stem ephindwe kabini i-O-rings yokutywinwa komqheba ongcono kunye nephedi yokunyusela eyakhelweyo yokongeza i-actuator. Ezi ziimpawu zepremiyamu yemisebenzi enzima kakhulu, ngelixa ivalve enemigangatho emibini ilukhetho oluthembekileyo lomsebenzi wenjongo ngokubanzi.

Ivalve yebhola emacala mabini isetyenziselwa ntoni?

Kufuneka umise okanye uqalise ukuhamba kwamanzi. Ngazo zonke iintlobo zevalve entsonkothileyo ekhoyo, kulula ukugqithisela isisombululo kunye nokuchitha ngaphezulu kwiimpawu ezingeyomfuneko zomsebenzi.

Ivalve yebhola enamacala amabini isetyenziswa kulawulo olusisiseko lokuvula/ukuvala kumbhobho othe tye. Inamazibuko amabini-i-inlet kunye ne-outlet-kwaye inika indlela elula, ethembekileyo yokuvala ukuhamba kwezicelo ezingenakubalwa.

Ivalve enendlela-mbini lolona hlobo luxhaphakileyo lwevalve ekhoyo. Wenza umsebenzi omnye: ukwahlula ukuhamba. Yicinge njengesibane sokutshintsha amanzi—inokuba ivuliwe okanye ivaliwe. Uninzi lweevalvu zebhola oya kuze uzibone, kubandakanywa phantse zonke iivalve ezinamaqhekeza amabini, zineendlela ezimbini. Ziyintsika yeenkqubo zemibhobho kuyo yonke indawo. Uwasebenzisela ukuvala amanzi ukuya kwindawo yokutshiza, ukwahlula isixhobo sokulungiswa, okanye njengendawo yokuvalwa kwesakhiwo. Ubulula bazo ngamandla abo. Oku kwahlukile kwiivalvu ze-multi-port, njengevalve yeendlela ezintathu, ezenzelwe ukuphambukisa ukuhamba, njengokuthumela amanzi phantsi kwenye indlela okanye enye. Kwi-95% yemisebenzi abathengi bakaBudi abajongana nayo, ivalve elula, eyomeleleyo, eneendlela ezimbini sisixhobo esifanelekileyo. Uyilo olunamacandelo amabini lukhetho oluhle kwaye luqheleke kakhulu kulo msebenzi ubalulekileyo.

Uthini umahluko phakathi kweqhekeza elinye kunye nevalve yebhola enamacandelo amathathu?

Ukhetha phakathi kwevalve enexabiso eliphantsi kunye neyona ibiza kakhulu. Ukwenza ukhetho olungalunganga kuthetha ukuba awukwazi ukulungisa ingxaki okanye uchithe imali kwizinto ongasoze uzisebenzise.

Umahluko ophambili kukusebenza. Ivalve yesiqwenga esinye yiyunithi etywiniweyo, elahlayo. Ivalve enamacandelo amathathu inokulungiswa lula ngelixa isaqhagamshelwe kumbhobho. Ivalve enamacandelo amabini ihleli embindini.

Ukuqonda isahlulo esinye kunye neenketho ezintathu-ntathu kubonisa ngokwenene ukuba kutheni i-valve yamacandelo amabini ithandwa kakhulu. Aipisi enyeIvalve yenziwe kumzimba omnye, iyenza ingabizi kakhulu kodwa ingenzeki ukuyivula ukuze ilungiswe. Yinto “yokusebenzisa kwaye ubeke endaweni” eyona nto ingcono kwimigca engabalulekanga. Kwelinye icala yiivalve enamacandelo amathathu. Inomzimba osembindini kunye neziqhagamshelo ezimbini ezahlukeneyo ezibanjwe kunye ngeebholiti ezinde. Olu yilo lukuvumela ukuba ususe lonke icandelo eliphakathi kwevalve ukuze ubuyisele amatywina ngaphandle kokusika umbhobho. Olu lukhetho oluphezulu lwezityalo zoshishino okanye amachibi okuthengisa apho ixesha lokuphumla libiza kakhulu. Iiziqwenga ezibiniivalve ibonelela ngolungelelwano olugqibeleleyo. Yomelele ngakumbi kwaye ihlala ihamba ngcono kuneqhekeza elinye, kwaye iyalungiseka. Ngelixa kufuneka uyisuse emgceni ukuyilungisa, lurhwebo olwamkeleke ngokugqibeleleyo ngexabiso layo elisezantsi xa lithelekiswa nevalve enamacandelo amathathu.

Uthelekiso loMzimba weValve

A iveluve yebhola enamacandelo amabinilihashe elithembekileyo, elinokulungiswa. Inika ibhalansi egqibeleleyo yamandla kunye neendleko phakathi kwecandelo elinye elilahlwayo kunye nenkonzo ephezulu, yoyilo lweziqwenga ezintathu kwizicelo ezininzi.
