Ukuxazulula ikhadi le-valve yokulawula noma ukuvinjelwa kwe-valve kagesi kuyi-valve ewusizo kakhulu?
Ngaphansi kwezimo ezijwayelekile, umlawuli uvame ukunamathela noma avinjwe, lesi simo senza abantu bakhathazeke ikakhulukazi, ngakho-ke vumela umnyango we-valve ye-macro ball ukukusiza ukuxazulula izinkinga zakho!
1) Indlela yokuhlanza
I-slag yokushisela, ukugqwala kanye nezinsalela epayipini kuzobangela ukuvinjelwa noma ukujamu endaweni ephumayo edonsayo, ingxenye eqondisayo kanye nembobo yebhalansi yekhava yevalvu engezansi, okuzobangela ubunzima kanye nokuklwebheka ebusweni be-spool kanye nendawo yokuqondisa, kanye nokushona phansi indawo yokubeka uphawu. Lokhu kuvame ukwenzeka ohlelweni olusha lokusebenza kanye nokusebenza kokuqala ngemva kokulungisa kabusha. Lokhu ukwehluleka okuvame kakhulu. Kulokhu, kumele zisuswe ukuze yokuhlanza, asuse slag, ezifana uphawu umonakalo ebusweni kufanele futhi kube emhlabathini; NGESIKHATHI ESIFANAYO, I-PLUG ESEZANSI IYAVULWA UKUZE KUHLANGANISE NOMA YIYIPHI OKUSELELE EZWILE NGEMBOBO YOKULINGANISA KUBONNET ENGAPHANSI KANYE NOKUSHINTSHISA UMUGQA. Ngaphambi kokuqalisa ukusebenza, vumela isilawuli sivuleke ngokugcwele, sigeleze ngokumaphakathi ngemva kwesikhathi esithile singene ekusebenzeni okuvamile.
2) Indlela yokuhlunga yangaphandle
Kokunye okunemvula okulula, okuqukethe izinhlayiya eziqinile zaphakathi nendawo enomthetho ojwayelekile wamavalvu, ezikhathini eziningi ku-throttle, umhlahlandlela uyavinjwa, kungaba igesi ye-scour kanye nesitimu ngaphandle kwepulaki engezansi yekhava yevalvu. Lapho i-valve ivinjiwe noma ibambekile, vula igesi yangaphandle noma i-valve ye-steam, ingaba esimweni se-valve yokulawula ukuqedela umsebenzi wokuhlanza, ukuze ukusebenza okujwayelekile kwe-valve.
3) Ukufakwa kwendlela yokuhlunga ipayipi
Kuma-valve amancane alawulayo, ikakhulukazi ama-valve alawula ukugeleza amancane kakhulu, igebe le-throttle lincane kakhulu, angeke kube khona insalela encane phakathi nendawo. Kulesi simo, kungcono ukufaka isihlungi kumbhobho ngaphambi kwe-valve ukuqinisekisa ukuhamba okubushelelezi kwe-medium. I-valve yokulawula ene-positioner, i-positioner ayisebenzi ngokujwayelekile, ukuvinjelwa kwegesi kuyiphutha elivame kakhulu. Ngakho-ke, lapho usebenza ne-positioner, kuyadingeka ukubhekana nomthombo womoya, futhi indlela evamile ukufaka i-valve yokunciphisa ingcindezi yokuhlunga emoyeni epayipini lomthombo womoya ngaphambi kokubeka indawo.
4) Khulisa indlela ye-throttle gap
Izinhlayiya eziqinile ezifana ne-medium noma zihlanjwe ku-slag welding we-pipe kanye nokugqwala ngenxa yokudlula umlomo ophefumulayo njengokuminyana, ujamu, njenge-fault, zingaguqula i-throttle gap ibe ucezu olukhudlwana lwe-throttle - indawo edonsayo yefasitela, ivule umgogodla we-valve. kanye nomkhono, kunokuba isiyingi esiyindilinga ngenxa yendawo enyakazisayo yokusabalalisa okugxilile, iphutha lingakhishwa kalula. Uma kuyi-valve yesihlalo esisodwa, esikabili ingashintshwa ibe yi-plunger spool “I-spool yomlomo emise okwe-V, noma ibe yivalvu yemikhono. Isibonelo, isitshalo esithile samakhemikhali sine-valve enezihlalo ezimbili evame ukunamathela, ngemva kokusetshenziswa okunconyiwe kwe-sleeve valve, inkinga yaxazululwa ngokushesha.
5) Indlela yokukhuhla emaphakathi
Ukusetshenziswa kwamandla okuguquguquka okuphakathi kwawo, ukuguquguquka nokuthatha kalula ukuduma, izinto ezixhunywa kalula, ukuze kuthuthukiswe umsebenzi wokuvimba ukuvinjwa kwevalvu. Izindlela ezijwayelekile yilezi: ① ukushintsha ukugeleza kohlobo oluvaliwe; ② Yamukela umzimba we-valve owenziwe lula; (3) Beka i-throttle orifice endaweni yokuguguleka okukhulu. Ngokusebenzisa le ndlela, ukunakekelwa kufanele kukhokhwe ekuthuthukiseni ukumelana nokuguguleka kwempahla ye-throttle.
6) iqonde indlela ye-Angle
Ukugeleza okuqondile wukugeleza okuhlanekezelwe kuka-S okunendlela yokugeleza eyinkimbinkimbi kanye nezindawo eziningi ezifile emigodini engaphezulu nephansi, okunikeza indawo yemvula emaphakathi. Ukuxhumeka kwe-angular, okuphakathi kufana nokugeleza ngendololwane engu-90, ukusebenza kahle kokukhuhla, indawo encane efile, kulula ukuyiklama ibe umugqa wokugeleza. Ngakho-ke, ukusetshenziswa kwe-valve yokulawula eqondile ukukhiqiza ukuvinjelwa okuncane kungashintshwa ku-Angle valve ukuze i-℃.
Imaphi ama-valve asebenza kakhulu kuvalvu yokulungisa kagesi?
Ama-valve okulawula ugesi ahlanganisa i-valve ye-butterfly elawulayo kagesi, i-valve yebhola elawulayo kagesi, i-valve yokulawula kagesi, i-valve yesango elawula ugesi, i-valve yokulawula isihlalo esisodwa kagesi, i-valve yokulawula izihlalo ezimbili kagesi kanye ne-valve yokulawula imikhono kagesi nezinye izinhlobo. I-valve yokulawula umoya ohlanganisa i-pneumatic film control valve, i-pneumatic control ball valve, i-pneumatic control flange butterfly valve kanye nokulawula umoya ohlotsheni lwe-butterfly valve.
I-valve yokulungiswa kwe-butterfly kagesi nayo ibizwa ngokuthi i-flip valve, iyisakhiwo esilula se-valve elawulayo, exhunywe ne-actuator, ingasetshenziselwa ukulawula ukushintshwa okuphakathi kwamapayipi anengcindezi ephansi. Epayipini ikakhulukazi idlala indima yokusika nokushaya. Ingxenye yokuvula nokuvala ye-valve ye-butterfly kagesi iyi-disc-shaped disc plate, ejikeleza ama-degree angu-90 eduze kwe-axis yayo emzimbeni we-valve, ukuze kuzuzwe injongo yokuvula nokuvala noma ukulungisa. I-valve ye-butterfly yokulungisa kagesi ihlukaniswe ngezigaba ezilandelayo:
Ukulungiswa kwe-butterfly valve kagesi (ububanzi obuncane) : inezici ze-torque encane yokuqala, umthamo omkhulu wokugeleza, ukulahlekelwa kokumelana nokugeleza okuncane, ukusebenza okuguquguqukayo, njll.
I-valve ye-butterfly yokulungiswa kukagesi, i-damper yokulungisa kagesi: ilungele i-metallurgical, imboni yokukhanya kanye nezinye izimboni zesithando somlilo esiqhumayo, isithando somlilo, igalaji likaphethiloli nezinye izikhathi zokusebenza.
I-NAC kagesi yokulungiswa kwe-butterfly valve: I-valve ye-butterfly yokulungiswa kagesi ye-NAC ihambisana ne-JB/T8528-97 “Izimo zobuchwepheshe zohlobo oluvamile lwedivayisi kagesi ye-valve”.
Kunezinhlobo ezimbili zamandla kagesi: 220V kanye ne-380V ugesi wezigaba ezintathu (abasebenzisi bangakhetha). Umkhiqizo uwuhlobo lwangaphandle futhi izinga lawo lokuvikela lingu-IP67.
