Udinga ivalvu enamandla kunengxenye eyodwa kodwa engabizi njengengxenye ezintathu. Ukukhetha engalungile kusho ukukhokha ngokweqile noma ukuthola ivalvu ongeke uyilungise uma kudingeka.

Ivalvu yebhola enezicucu ezimbili yakhiwe izingxenye ezimbili zomzimba eziyinhloko ezihlanganisa ndawonye, ​​zibambe ibhola futhi zivale ngaphakathi. Lo mklamo unamandla kunevalvu yengxenye eyodwa futhi uvumela ukulungiswa, yize kufanele iqale isuswe epayipini.

I-valve yebhola enezicucu ezimbili iyindlela yokusebenza ngempela emhlabeni wokufaka amapayipi. Ingenye yezinhlobo ezivame kakhulu engixoxa ngazo nabalingani bami, njengoBudi, umphathi wokuthenga e-Indonesia. Amakhasimende akhe, ikakhulukazi abangosonkontileka abajwayelekile kanye nabasabalalisi, adinga ikhambi elithembekile nelingabizi kakhulu lemisebenzi yansuku zonke. Umklamo wezicucu ezimbili ufika kahle kuleyo ndawo enhle. Inikeza ukuthuthukiswa okukhulu kwamandla kanye nokusebenziseka kahle ngaphezu kwama-valve ayisisekelo ngaphandle kwezindleko eziphakeme zamamodeli ezimboni ayinkimbinkimbi. Ukuze uqonde ngempela inani layo, kufanele ubone ukuthi ifanelana kuphi esithombeni esikhulu.

Iyini ivalvu enezicucu ezimbili?

Ungabona umthungo lapho umzimba we-valve uhlanganiswe khona, kodwa kusho ukuthini lokho? Ukuqonda ukwakheka kwawo kubalulekile ekwazini ukuthi kuyisinqumo esifanele yini empilweni yesikhathi eside yesistimu yakho.

Ivalvu enezicucu ezimbili inomzimba oyinhloko kanye nengxenye yesibili, isixhumi sokugcina, esiyifaka ngezikulufo. Lokhu kuxhuma okunezintambo kugcina ibhola nezihlalo, okwenza ivalvu ilungele ukusetshenziswa futhi imelane kakhulu nengcindezi kunomklamo wengxenye eyodwa.

Ukwakhiwa kwe-ivalvu enezingcezu ezimbiliisici sayo esiyinhloko. Cabanga ngomzimba wevalvu wenziwe ngezigaba ezimbili. Ingxenye enkulu ibamba isiqu kanye nesibambo, kanti ingxenye encane empeleni iyisivalo esinezintambo. Uma zihlanganiswa ndawonye, ​​​​zibamba ibhola kanye nezihlalo ezithambile (ngokuvamile ezenziwe nge-PTFE) ezidala uphawu. Lo mklamo womzimba onezintambo unamandla kakhulu kunevalvu enengxenye eyodwa, lapho ibhola lifakwa khona ngembobo encane, evame ukudinga ibhola elincane (imbobo encishisiwe). Ukwakhiwa kwezingcezu ezimbili kuvumela ibhola elikhulu, "eligcwele imbobo", okusho ukuthi imbobo ebholeni ilingana nepayipi, okuholela ekugelezeni okungcono ngokulahlekelwa okuncane kwengcindezi. Uma uphawu luguga, ungaluvula umzimba, ushintshe izingxenye, bese ulubuyisela ekusebenzeni. Kuyindawo enhle ephakathi kwamakhasimende amaningi eBudi adinga ivalvu eqinile futhi elungisekayo.

Uyini umehluko phakathi kwevalvu yebhola yohlobo 1 nevalvu yebhola yohlobo 2?

Uzwa amagama anjengokuthi “Uhlobo 1″ kanye “Uhlobo 21″ kodwa awuqiniseki ukuthi asho ukuthini. Ukukhetha ngokusekelwe kula magama ngaphandle kokuwaqonda kungasho ukuphuthelwa izici zokuphepha ezibalulekile.

La magama awabhekiseli ekwakhiweni komzimba (njengezicucu ezimbili) kodwa abhekisela ezizukulwaneni zomklamo, ngokuvamile wama-valve e-union angempela. I-“Type 21″ iwuphawu olufushane lwemboni lomklamo wesimanje onezici zokuphepha ezithuthukisiwe kanye nokusebenziseka kalula.

Kubaluleke kakhulu ukungadidanisi isitayela somzimba nalezi zinombolo "zohlobo". Ivalvu "yezingcezu ezimbili" ichaza indlela umzimba owakhiwe ngayo ngokomzimba. Amagama anjengokuthi "Uhlobo 21," ngakolunye uhlangothi, achaza isethi ethile yezici zesimanje, futhi cishe atholakala njalo kumavalvu e-union angempela ezingxenye ezintathu. Kufanele ngicacise lokhu eqenjini likaBudi ngezinye izikhathi. Ikhasimende lingase licele"Ivalvu yohlobo lwe-21 enezingcezu ezimbili,"kodwa lezo zici ziyingxenye yesigaba se-valve esihlukile. Isici esibaluleke kakhulu sesitayela sohlobo 21 yi-i-union nut ephephile ngamabhulokhi, okuvimbela ivalvu ukuthi ingavulwa ngengozi ngenkathi uhlelo lungaphansi kwengcindezi. Lesi yisici esibalulekile sokuphepha. Ngokuvamile zifaka phakathi izindandatho ze-O-stem ezimbili zokuvala kangcono isibambo kanye nephedi yokufaka eyakhelwe ngaphakathi yokwengeza i-actuator. Lezi yizici zekhwalithi ephezulu zemisebenzi enzima kakhulu, kuyilapho ivalvu ejwayelekile enezingcezu ezimbili iyindlela ethembekile yomsebenzi wenhloso ejwayelekile.

Iyini ivalvu yebhola enezindlela ezimbili esetshenziselwa yona?

Udinga nje ukumisa noma ukuqala ukugeleza kwamanzi. Njengoba kunezinhlobo eziningi zamavalvu eziyinkimbinkimbi ezitholakalayo, kulula ukwenza ikhambi libe nzima kakhulu futhi usebenzise imali eningi ezintweni ezingadingekile zomsebenzi.

I-valve yebhola enezindlela ezimbili isetshenziselwa ukulawula okuyisisekelo kokuvula/ukuvala epayipini eliqondile. Inamachweba amabili—ukungena kanye nendawo yokuphuma—futhi inikeza indlela elula nethembekile yokuvala ukugeleza kwezinhlelo zokusebenza eziningi.

Ivalvu enezindlela ezimbili uhlobo lwevalvu oluvame kakhulu olukhona. Yenza umsebenzi owodwa: ihlukanisa ukugeleza. Cabanga ngayo njengesibani sokukhanyisa amanzi—kungaba ukuthi ivuliwe noma icishiwe. Iningi lamavalvu ebhola ozoke uwabone, kufaka phakathi cishe wonke amavalvu anezicucu ezimbili, angamavalvu anezindlela ezimbili. Angumgogodla wezinhlelo zamapayipi yonke indawo. Uwasebenzisa ukuvala amanzi endaweni yokufafaza, ukuhlukanisa ucezu lwemishini yokulungisa, noma njengokuvala okuyinhloko kwesakhiwo. Ubulula bawo amandla awo. Lokhu kuhlukile kumavalvu anezimbobo eziningi, njengevalvu enezindlela ezintathu, eklanyelwe ukuphambukisa ukugeleza, njengokuthumela amanzi endleleni ethile noma kwenye. Ngemisebenzi engama-95% amakhasimende kaBudi abhekana nayo, ivalvu yebhola elula, eqinile, enezindlela ezimbili iyithuluzi elifanele. Umklamo wezingxenye ezimbili uyisinqumo esihle kakhulu nesivamile kakhulu kulo msebenzi oyisisekelo.

Uyini umehluko phakathi kwevalvu yebhola yesiqephu esisodwa nevalvu yesiqephu ezintathu?

Ukhetha phakathi kwevalvu eshibhile kakhulu nebiza kakhulu. Ukwenza ukukhetha okungalungile kusho ukuthi awukwazi ukulungisa inkinga noma uchithe imali ezintweni ongeke uzisebenzise.

Umehluko oyinhloko ukuthi iyasebenza kahle. Ivalvu enengxenye eyodwa iyiyunithi evaliwe, elahlwayo. Ivalvu enezingxenye ezintathu ingalungiswa kalula ngenkathi isaxhunywe epayipini. Ivalvu enezingxenye ezimbili ihlala phakathi.

Ukuqonda izinketho ze-one-piece kanye ne-three-piece kubonisa ngempela ukuthi kungani i-valve ye-two-piece ithandwa kangaka.ucezu olulodwaIvalvu yenziwe ngomzimba owodwa, okwenza kube okungabizi kodwa kungenzeki ukuyivula ukuze ilungiswe. Kuyinto "yokusebenzisa nokufaka esikhundleni" engcono kakhulu emigqeni engeyona ebalulekile. Ngakolunye uhlangothi kukhonaivalvu enezingcezu ezintathu. Inomzimba ophakathi kanye nezixhumi ezimbili ezihlukene ezibanjwe ndawonye ngamabhawodi amade. Lo mklamo ukuvumela ukuthi ususe yonke ingxenye ephakathi yevalvu ukuze ufake izivalo ngaphandle kokunquma ipayipi. Lena yisinqumo esiphezulu sezimboni noma amachibi okuhweba lapho isikhathi sokungasebenzi sibiza kakhulu.izingcezu ezimbiliIvalvu inikeza ukuvumelana okuphelele. Iqinile kakhulu futhi ivame ukuba nokugeleza okungcono kuneyodwa, futhi iyalungiseka. Nakuba kufanele uyisuse emgqeni ukuze uyilungise, lokho kuyindlela eyamukelekayo ngokuphelele ngentengo yayo ephansi uma kuqhathaniswa nevalvu enezicucu ezintathu.

Ukuqhathaniswa Kohlobo Lomzimba Wevalvu

Isiphetho

A ivalvu yebhola enezingcezu ezimbiliiyihhashi elisebenzayo elithembekile nelilungisekayo. Linikeza ibhalansi ephelele yamandla kanye nezindleko phakathi kwento eyodwa elahlwayo kanye nemiklamo yesevisi ephezulu, yezingcezu ezintathu zezinhlelo zokusebenza eziningi.
