Udinga ukukhetha i-ball valve, kodwa uhlobo lwayo lukhulu kakhulu. Ukukhetha uhlobo olungalungile kungasho ukungalingani kahle, ukuvuza kwesikhathi esizayo, noma uhlelo oluyiphupho elibi ukulugcina.

Izinhlobo ezine eziyinhloko zama-ball valve zihlukaniswa ngokwakhiwa komzimba wazo: ucezu olulodwa,izingcezu ezimbili, izingcezu ezintathu, kanye ne-top entry. Umklamo ngamunye unikeza ibhalansi ehlukile yentengo, amandla, kanye nokulula kokulungiswa, okwenza kube ngokwezinhlelo zokusebenza ezithile kanye nezidingo zokulungisa.

Ukuqonda lezi zinhlobo eziyisisekelo kuyisinyathelo sokuqala, kodwa kumane kuyisiqalo. Ngivame ukuba nale ngxoxo noBudi, umphathi oyinhloko wokuthenga engibambisene naye e-Indonesia. Amakhasimende akhe ayadideka yiwo wonke amagama asetshenziswayo. Uthola ukuthi uma esekwazi ukuchaza umehluko oyinhloko ngendlela elula, amakhasimende akhe azizwa eqiniseka kakhulu. Angasuka ekubeni nokungaqiniseki aye ekwenzeni ukukhetha kochwepheshe, kungakhathaliseki ukuthi athenga ivalvu elula yomugqa wokunisela noma eyinkimbinkimbi kakhulu yenqubo yezimboni. Ake sichaze ukuthi lezi zinhlobo zisho ukuthini ngempela kuwe.

Yiziphi izinhlobo ezahlukene zamavalvu ebhola?

Ubona amagama anjengokuthi “i-full port,” “trunnion,” kanye “ne-floating ball” kuma-spec sheet. Leli gama lobuchwepheshe lenza kube nzima ukwazi ukuthi uthola ukusebenza okulungile yini ngokwezidingo zakho ezithile.

Ngaphandle kwesitayela somzimba, ama-valve ebhola athayishwa ngosayizi wawo webhore (imbobo egcwele uma iqhathaniswa nembobo ejwayelekile) kanye nomklamo wangaphakathi webhola (ontantayo vs. i-trunnion). Imbobo egcwele iqinisekisa ukugeleza okungavinjelwe, kuyilapho imiklamo ye-trunnion iphatha ukucindezeleka okuphezulu kakhulu.

Ake singene shí ezinhlotsheni zomzimba nezangaphakathi. Ukwakhiwa komzimba kumayelana nokufinyelela ekunakekelweni.ucezu olulodwaivalvu iyiyunithi evaliwe; ayibizi kakhulu kodwa ayikwazi ukulungiswa.izingcezu ezimbiliUmzimba wevalvu uhlukana phakathi, okuvumela ukulungiswa, kodwa kufanele uwususe epayipini kuqala. Umklamo olula kakhulu ukulungiswa yi-izingcezu ezintathuivalvu. Ingxenye ephakathi equkethe ibhola ingasuswa ngokukhumula amabhawodi amabili, kushiye ukuxhumana kwamapayipi kuphelele. Lokhu kulungele imigqa edinga isevisi njalo. Ngaphakathi, “imbobo” noma imbobo ebholeni ibalulekile.imbobo egcweleivalvu inomgodi olingana nowepayipi, okwenza kube nomkhawulo wokugeleza okungekho.imbobo ejwayelekileincane kancane, okuyinto efanele ukusetshenziswa kakhulu. Okokugcina, cishe wonke ama-valve ebhola e-PVC asebenzisa i-ibhola elintantayoumklamo, lapho ingcindezi yesistimu isunduza ibhola ngokuphephile esihlalweni esingezansi ukuze kudalwe uphawu.

Izinhlobo ze-Ball Valve Ngokubuka

Yiziphi izinhlobo ezahlukene zokuxhumeka kwe-ball valve?

Usuyitholile ivalvu ephelele, kodwa manje kufanele uyixhume. Ukukhetha indlela yokuxhuma engalungile kungaholela ekufakweni okunzima, ukuvuza okuqhubekayo, noma uhlelo ongeke ukwazi ukulusevisa ngaphandle kwe-hacksaw.

Izinhlobo zokuxhuma ezivame kakhulu zama-ball valve yizisekelo ze-solvent-weld zesibopho se-PVC esihlala njalo, iziphetho ezinentambo zokuhlanganisa izinto ezahlukene, iziphetho ezine-flanged zamapayipi amakhulu, kanye nokuxhumeka kwe-union yangempela ukuze kube lula ukusebenza.

Uhlobo lokuxhuma olukhethayo luchaza indlela ivalvu ehlangana ngayo namapayipi akho.Isokhethinoma ukuxhumeka "okushelelayo" kusetshenziswa ipayipi le-PVC, okudala isibopho esihlala njalo, esingavuzi kusetshenziswa usimende we-solvent. Lokhu kulula futhi kuthembekile kakhulu.Kufakwe uchungechungeUkuxhumeka (i-NPT noma i-BSPT) kukuvumela ukuthi ubophe ivalvu epayipini elinomucu, okuyinto enhle kakhulu yokuxhuma i-PVC ezingxenyeni zensimbi, kodwa idinga isivali sentambo nokufakwa ngokucophelela ukuze kugwenywe ukuvuza. Kumapayipi amakhulu (ngokuvamile angaphezu kwamasentimitha amabili),okujiyilekusetshenziswa ukuxhumeka. Basebenzisa amabhawodi kanye ne-gasket ukudala uphawu oluqinile, oluphephile, nolususwa kalula. Kodwa ukuze kube lula ukugcinwa emapayipini amancane, akukho okudlulaUbumbano Lweqinisoivalvu. Lo mklamo unama-union nuts amabili akuvumela ukuthi ususe ngokuphelele umzimba ophakathi wevalvu ukuze ulungiswe noma ushintshwe ngenkathi iziphetho zokuxhuma zihlala zinamathelisiwe epayipini. Kungcono kakhulu kuzo zombili lezi zindawo: uxhumano oluqinile kanye nensizakalo elula.

Ukuqhathanisa Izinhlobo Zokuxhumana

Yiziphi izinhlobo ezahlukene zama-valve e-MOV?

Ufuna ukwenza uhlelo lwakho lube ngokuzenzakalelayo, kodwa i-“MOV” izwakala njengemishini yezimboni eyinkimbinkimbi. Awuqiniseki ngomthombo wamandla, izinketho zokulawula, nokuthi ingabe iyasebenza yini kuphrojekthi yakho.

I-MOV imele i-Ivalvu Esebenza Ngenjini, okuyinoma yiliphi i-valve elawulwa yi-actuator. Izinhlobo ezimbili eziyinhloko yi-actuator kagesi, esebenzisa injini kagesi, kanye ne-pneumatic actuators, esebenzisa umoya ocindezelwe ukuze isebenze i-valve.

I-MOV akuyona uhlobo olukhethekile lwe-valve; iyi-valve ejwayelekile ene-actuator efakwe kuyo. Uhlobo lwe-actuator yilona olubalulekile.Ama-actuator kagesiyizona ezivame kakhulu kuma-valve ebhola le-PVC ezinhlelweni zamanzi. Zisebenzisa injini encane ukuvula noma ukuvala i-valve futhi zitholakala ngama-voltage ahlukahlukene (njenge-24V DC noma i-220V AC) ukuze zifane nomthombo wakho wamandla. Zilungele izinhlelo zokusebenza ezifana nezindawo zokunisela ezenzakalelayo, ukulinganisa ukwelashwa kwamanzi, noma ukugcwalisa ithangi elikude.Ama-actuator omoyaSebenzisa amandla omoya ocindezelwe ukuze uvule noma uvale ivalvu ngokushesha okukhulu. Zinamandla kakhulu futhi zithembekile kodwa zidinga i-air compressor kanye nemigqa yomoya ukuze zisebenze. Ngokuvamile uzibona kuphela ezitshalweni ezinkulu zezimboni lapho umoya ocindezelwe usuvele uyingxenye yengqalasizinda. Kwabaningi bamakhasimende kaBudi, ama-actuator kagesi anikeza ibhalansi efanele yokulawula, izindleko, kanye nobulula.

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

Ufunda ishidi lemininingwane bese ubona elithi “Type 21 Ball Valve” futhi awazi ukuthi kusho ukuthini lokho. Ukhathazekile ukuthi ungase uphuthelwe imininingwane ebalulekile mayelana nokuphepha noma ukusebenza kwayo.

Leli gama livame ukubhekisela ezizukulwaneni zama-valve ebhola le-union angempela avela kumikhiqizo ethile. I-“Type 21″ isibe yisifushaniso somklamo wesimanje, osebenza kahle kakhulu ohlanganisa izici ezibalulekile zokuphepha kanye nokusebenziseka kalula njenge-union nut ephephile ngamabhulokhi.

Amagama athi “Uhlobo 1” noma “Uhlobo 21” awawona amazinga ajwayelekile kubo bonke abakhiqizi, kodwa abhekisela kumiklamo enethonya eye yakha imakethe. Cabanga ngokuthi “Uhlobo 21” lumelela indinganiso yesimanje, ye-premium ye-valve ye-union yangempela. Lapho siklama ama-valve ethu e-Pntek true union, safaka izimiso ezenza le miklamo ibe mihle kangaka. Isici esibaluleke kakhulu yi-I-Union Nut Ephephile Nge-BlockLena indlela yokuphepha lapho i-nut inentambo ekhiyayo, okwenza kube nzima ukuyivula ngengozi ngenkathi ingaphansi kwengcindezi. Lokhu kuvimbela ukuqhuma okuyingozi. Ezinye izici ezivamile zalesi sitayela zifaka phakathiizindandatho ze-O ezimbili zesiquukuze kuvikelwe ukuvuza okuphezulu esibambweni kanyeiphedi yokufaka ehlanganisiwe(ngokuvamile ngokwezinga le-ISO 5211) okwenza kube lula ukwengeza i-actuator kagesi kamuva. Akuyona nje i-valve; kuyingxenye yesistimu ephephile, ethembekile, futhi evikela ikusasa.

Isiphetho

Izinhlobo ezine eziyinhloko zamavalvu zibhekisela kwisitayela somzimba, kodwa ukuqonda kweqiniso kuvela ekwazini imbobo, uxhumano, kanye nezinketho zokuqalisa. Lolu lwazi lukuvumela ukuthi ukhethe ivalvu efanele noma yimuphi umsebenzi.
