Udinga ukufaka i-valve, kodwa ukukhetha uhlobo olungalungile kungase kusho amahora omsebenzi owengeziwe kamuva. Ukulungisa okulula kungaphoqa ukuthi usike amapayipi futhi uvale lonke uhlelo.

Ivalvu yebhola ephindwe kabili ingakhishwa ngokuphelele epayipini ukuze lilungiswe, kuyilapho i-valve eyodwa yenyunyana ayikwazi. Lokhu kwenza idizayini yezinyunyana ezimbili iphakame kakhulu ekunakekeleni nasekusebenzeleni isikhathi eside.

Ikhono lokusevisa i-valve kalula liyisici esikhulu ezindlekweni eziphelele zobunikazi. Kuyisihloko esibalulekile engixoxa ngaso nozakwethu abafana no-Budi, umphathi wokuthenga e-Indonesia. Amakhasimende akhe, ikakhulukazi lawo asezindaweni zezimboni, awakwazi ukukhokhela izikhathi zokuphumula ezinde. Kudingeka bakwazi ukushintsha izigxivizo zevalvu noma wonke umzimba we-valve ngemizuzu, hhayi amahora. Ukuqonda umehluko wemishini phakathi kwemiklamo yenyunyana eyodwa kanye nekabili kuzokusiza ukuthi ukhethe i-valve ekongela isikhathi, imali, kanye nekhanda elibuhlungu elibuhlungu emgwaqeni.

Uyini umehluko phakathi kwevalve yebhola lenyunyana eyodwa kanye ne-double union ball valve?

Ubona ama-valve amabili abukeka afana kodwa anamagama namanani ahlukene. Lokhu kukwenza uzibuze ukuthi ngabe inketho yenyunyana eyodwa eshibhile “yinhle ngokwanele” kuphrojekthi yakho.

Inyunyana ekabili inezixhumi ezinentambo kuzo zombili iziphetho, ezivumela ukuthi zisuswe ngokuphelele. Inyunyana eyodwa inesixhumi esisodwa, okusho ukuthi uhlangothi olulodwa luzinzile unomphela, ngokuvamile ngosimende oncibilikayo.

Kucabange njengokulungisa isondo lemoto. I-valve yokuhlanganisa kabili ifana nesondo elibanjwe ngamantongomane; ungakwazi ukulikhipha lonke isondo kalula ukuze ulilungise. I-valve yokuhlanganisa eyodwa ifana nesondo elishiselwe e-asileni ngakolunye uhlangothi; awukwazi ngempela ukukususa ukuze uthole isevisi. Ungakwazi ukunqamula ingxenye eyodwa kuphela bese uyisusa endleleni. Uma umzimba we-valve ngokwawo uhluleka noma udinga ukufaka esikhundleni sezimpawu, iinyunyana kabilidesign iphezulu kakhulu. Osonkontileka bakwaBudi bazosebenzisa ama-valve asebenza ngama-double union kuphela uma befaka izicelo ezibucayi ngoba bangakwazi ukushintshwa ngokuphelele ngaphansi kwemizuzu emihlanu ngaphandle kokusika ipayipi elilodwa. Izindleko ezincane ezengeziwe ezingaphambili zizikhokhela ngokwazo lapho kudingekile ukunakekelwa kokuqala.

Uyini umehluko phakathi kwe-valve eyodwa ne-valve ephindwe kabili?

Uzwa amagama afana ne-"valve eyodwa" kanye "ne-valve ephindwe kabili" bese uyadideka. Ukhathazekile ngokuthi ungase utolike ngokungeyikho imininingwane yephrojekthi, okuholela kuma-oda angalungile.

“I-valve eyodwa” ngokuvamile isho ivalvu elula, enesiqephu esisodwa esingenazinyunyana. “I-valve ephindwe kabili” ivamise ukusho isifinyezo sokuthi “i-valve ye-double union ball,” okuyiyunithi ye-valve eyodwa enokuxhumana okubili kwezinyunyana.

Amatemu angaba nzima. Ake sicacise. "I-valve eyodwa" ngendlela elula kakhulu ngokuvamile "i-compact" nomai-valve yebhola yocezu olulodwa. Kuyiyunithi evaliwe enamathiselwe ngqo epayipini. Ishibhile futhi ilula, kodwa uma ihluleka, kufanele uyinqume. "I-valve ephindwe kabili" noma "i-valve yokuhlanganisa kabili” ibhekisela kumkhiqizo wethu weqhawe: iyunithi eneziqephu ezintathu (iziphetho ezimbili zenyunyana kanye nomzimba omkhulu) evumela ukususwa kalula. Kubalulekile ukungaphambani lokhu nokusethwa kwe-"double block", okubandakanya ukusebenzisa ama-valve amabili ahlukene, angawodwana wokuhlukaniswa nokuphepha okuphezulu. Ku-99% wezinhlelo zamanzi, i-valve yebhola eyodwa "double union" inikeza ibhalansi yebhola evikelekile futhi inikeze ibhalansi evikelekile ye-P yokuvala isevisi kalula. noma yikuphi ukufakwa kwekhwalithi.

I-Valve Serviceability Ukuqhathanisa

Uyini umehluko phakathi kwe-valve yebhola yohlobo 1 nohlobo 2?

Ubheke ipulani elidala noma ishidi lokucaciswa kwesincintisana naye futhi ubone “Uhlobo 1″ noma “Uhlobo 2″ valvu. Le jargon esiphelelwe yisikhathi idala ukudideka futhi yenza kube nzima ukuqhathanisa nemikhiqizo yesimanje.

Lawa amagama amadala. “Uhlobo 1″ ngokuvamile lubhekiselwa kumklamo oyisisekelo, wocezu olulodwa. “Uhlobo 2″ lubhekisele kumklamo omusha onokusebenziseka okuthuthukisiwe, oguqukele kumavalvu ebhola eqembu langempela lanamuhla.

Kucabange njengokuthi "Uhlobo 1" lwemoto oluyimodeli T futhi "Uhlobo 2" oluyimoto yesimanje. Imiqondo iyafana, kodwa ubuchwepheshe kanye nomklamo kuhlukene ngomhlaba. Emashumini eminyaka adlule, imboni yasebenzisa la magama ukuze ihlukanise imiklamo ye-valve yebhola. Namuhla, imigomo ngokuvamile ayisasebenzi, kodwa isengavela ezinhlelweni ezindala. Uma ngibona lokhu, ngichazela ozakwethu abafana noBudi ukuthi iPntek yethuama-valve ebhola lezinyunyana zangempelaziwukuvela kwesimanjemanje komqondo we-"Type 2". Zakhiwe kusukela phansi ukuze zikwazi ukushintshwa kalula futhi zisuswe emgqeni. Kufanele uhlale ucacise "i-valve yebhola lenyunyana yeqiniso" ukuze uqiniseke ukuthi uthola umkhiqizo wesimanjemanje, osebenziseka ngokugcwele, hhayi idizayini ephelelwe yisikhathi eshidini lezicaciso lamashumi eminyaka ubudala.

Uyini umehluko phakathi kwamavalvu ebhola e-DPE ne-SPE?

Ufunda ishidi ledatha yobuchwepheshe elikhuluma ngezihlalo ze-DPE noma ze-SPE. Lawa ma-akhronimi ayadida, futhi wesaba ukuthi ukukhetha okungalungile kungadala isimo sokucindezela esiyingozi epayipini lakho.

I-SPE (I-Single Piston Effect) ne-DPE (i-Double Piston Effect) ibhekisela endleleni izihlalo zamavalvu ezisingatha ngayo ukucindezela lapho ivalvu ivaliwe. I-SPE iyindinganiso yamavalvu e-PVC, njengoba ikhipha ngokuzenzakalelayo ingcindezi ngokuphepha.

Lokhu kuthola ubuchwepheshe, kodwa umqondo ubalulekile ekuphepheni. Ku-valve evaliwe, ukucindezela kwesinye isikhathi kungavaleleka emgodini womzimba omaphakathi.

• I-SPE (I-Single Piston Effect):Leli izinga lomkhakha lamavalvu ebhola e-PVC enhloso ejwayelekile. AnIsihlalo se-SPEama-seal ngokumelene nokucindezela okuvela ohlangothini olungenhla nomfula. Nokho, uma ingcindezi iyandangaphakathiumzimba we-valve, ungaphusha ngokuphepha udlule isihlalo esingezansi nomfula. Kuwumklamo ozikhululayo.
• I-DPE (I-Double Piston Effect): A Isihlalo se-DPEkungaba uphawu ngokumelene ingcindezi evelakokubiliizinhlangothi. Lokhu kusho ukuthi ingabamba ingcindezi emgodini womzimba, okungaba yingozi uma inyuka ngenxa yokwanda kokushisa. Lo mklamo owenzelwe izinhlelo zokusebenza ezikhethekile futhi udinga uhlelo oluhlukile lokukhulula imbobo yomzimba.

Kuzo zonke izinhlelo zokusebenza zamanzi ezijwayelekile, njengalezo amaklayenti ka-Budi anazo, idizayini ye-SPE iphephe kakhudlwana futhi lokho esikwakhela kukho.Ama-valve e-Pntek. Ivimbela ukunqwabelana kwengcindezi eyingozi ngokuzenzakalelayo.

Isiphetho

I-valve ye-double union ball ingcono kunoma iyiphi isistimu edinga ukulungiswa, njengoba ingasuswa ngokugcwele ngaphandle kokusika amapayipi. Ukuqonda i-valve design kuqinisekisa ukuthi ukhetha ngendlela efanele.
