Ukusombulula ikhadi levalve yolawulo okanye isenzeko sokuvaleka kwevalve yombane yeyona isebenzayo?
Phantsi kweemeko eziqhelekileyo, umlawuli uhlala ebambekile okanye evaliwe, le meko yenza abantu bakhathazeke ngakumbi, ke vumela umnyango wevalve yebhola enkulu ukukunceda ukusombulula iingxaki zakho!
1) Indlela yokucoca
Ukuwelda i-slag, irusi kunye nentsalela kumbhobho kuya kubangela ukuvaleka okanye i-jam kwi-orifice evuthuzayo, inxalenye yesikhokelo kunye nomngxuma olungeleleneyo wesigqubuthelo sevalvu esezantsi, nto leyo eya kubangela ubunzima kunye nokukrwela kumphezulu we-spool kunye nomphezulu wesikhokelo, kunye nokuhlenga kwi-valve. indawo yokutywina. Oku kaninzi kwenzeka kwinkqubo entsha yokusebenza kunye nomsebenzi wokuqala emva kokulungiswa kwakhona. Le yeyona ntsilelo ixhaphakileyo. Kule meko, kufuneka isuswe ukucoca, susa i-slag, njengokutywina umonakalo wendawo kufuneka kwakhona ube ngumhlaba; NGEXESHA ELINYE, I-BOTTOM PLUG IVULELWE UKUGUQUKA NAYAYIPHI NA INSILELA EYE YAWELA NGINGXOXO YEBHNTI ENGAPHANTSI KWAYE UKUGUQUKA UMDA. Ngaphambi kokuqalisa ukusebenza, vumela isilawuli sivuleke ngokupheleleyo, ukuhamba okuphakathi emva kwexesha elithile ukuya ekusebenzeni okuqhelekileyo.
2) Indlela yokucoca yangaphandle
Kuba lula ukuna, eziqulathe amasuntswana aqinileyo ophakathi kunye nommiselo wevalvu eqhelekileyo, rhoqo kwi-throttle, isikhokelo sivaliwe, sinokuba yigesi ye-scour kunye nomphunga ngaphandle kweplagi esezantsi yesivalo sevalve. Xa i-valve ivaliwe okanye ibambekile, vula igesi yangaphandle okanye i-valve ye-steam, ingaba kwimeko yevalve yokulawula ukugqiba umsebenzi wokugungxula, ukwenzela ukuba umsebenzi oqhelekileyo wevalve.
3) Ukufakwa kwendlela yokucoca umbhobho
Kwiivalvu ezincinci zokulawula i-caliber, ngakumbi i-valve encinci yokulawula ukuhamba, i-gap ye-throttle incinci kakhulu, akunakubakho ntsalela encinci phakathi. Kule meko, kukulungele ukufaka isihluzo kwipayipi phambi kwevalve ukuqinisekisa ukuhamba kakuhle kwendawo. Ivalve yokulawula ene-positioner, i-positioner ayisebenzi ngokuqhelekileyo, ukuvaleka kwegesi ukuvaleka yeyona mpazamo ixhaphakileyo. Ngoko ke, xa usebenza ne-positioner, kuyimfuneko ukujongana nomthombo womoya, kwaye indlela eqhelekileyo kukufaka i-valve yokunciphisa uxinzelelo lomoya kumbhobho womthombo womoya phambi kwendawo yokubeka.
4) Yandisa indlela ye-throttle gap
Amasuntswana aqinileyo anjengendawo ephakathi okanye ahlanjwe kumbhobho welding slag kunye nomhlwa ngenxa yokudlula komlomo we-throttle njengokuxinana, ijem, efana nempazamo, inokuguqula i-throttle gap iqhekeza elikhulu le-throttle-indawo yokutshiza yefestile, vula undoqo wevalve. kunye ne-sleeve, kunokuba i-circumference yesangqa ngenxa ye-throttling area yokusasazwa koxinzelelo, impazamo inokukhutshwa ngokulula. Ukuba yinto enye, ivelufa yesitulo esiphindwe kabini ingatshintshwa ibe yi-plunger spool “i-V-shaped mouth spool, okanye ivalufa yomkhono. Umzekelo, isityalo esithile sekhemikhali sinevalve enezihlalo ezibini ehlala ibambekile, emva kokusetyenziswa kwevalve yomkhono, ingxaki yasonjululwa kwangoko.
5) Indlela yokucoca ephakathi
Ukusetyenziswa kwamandla okugungxulwa okuphakathi, ukugungxulwa kunye nokuthatha lula ukugungxulwa, kulula ukuplaga izinto, ukuze kuphuculwe umsebenzi ochasene nokuvalwa kwevalve. Iindlela eziqhelekileyo zezi: ① utshintsho kuhlobo oluvaliweyo lokuqukuqela; ② Yamkela umzimba wevalvu olungelelanisiweyo; (3) Beka i-throttle orifice kwindawo yokukhukuliseka okukhulu. Ngokusebenzisa le ndlela, ingqwalasela kufuneka ihlawulwe ekuphuculeni ukuxhathisa ukukhukuliseka kwezinto ze-throttle.
6) ngqo ukuya kwindlela ye-Angle
Ukuhamba ngokuthe ngqo kukuhamba kwe-S eguquliweyo kunye nendlela yokuhamba eyinkimbinkimbi kunye neendawo ezininzi ezifileyo kwimingxuma ephezulu nangaphantsi, ebonelela ngendawo yokunetha kwemvula ephakathi. Uxhulumaniso lwe-angular, i-medium ifana nokuhamba nge-90 elbow, ukusebenza kakuhle kokucoca, indawo encinci efileyo, kulula ukuyila kumgca wokuhamba. Ke ngoko, ukusetyenziswa kwevalve yokulawula ethe tye ukuvelisa ukuvaleka okuncinci kunokutshintshwa kwivalve ye-Angle ukuze i-℃.
Zeziphi ezinye iivalvu ezisebenzayo kwivalve yohlengahlengiso lombane?
Iivalve zokulawula umbane zibandakanya ivalve yokulawula ibhabhathane yombane, ivalve yebhola elawula umbane, ivalve yokulawula umbane, ivalve yokulawula umbane, ivalve yokulawula isitulo sombane, ivalve yokulawula izihlalo ezibini kunye nevalve yokulawula imikhono yombane kunye nezinye iintlobo. Ivalve yokulawula ipneumatic equka ivalve yokulawula ifilimu yomoya, ivalve yebhola yomoya yokulawula umoya, ivalve yebhabhathane yolawulo lwepneumatic kunye nolawulo lwe-pneumatic kuhlobo lwevalve yebhabhathane.
Ivalve yebhabhathane yohlengahlengiso lombane ikwabizwa ngokuba ivelufa yeflip, sisakhiwo esilula sevalve yokulawula, edityaniswe ne-actuator, ingasetyenziselwa ulawulo lombhobho ophakathi woxinzelelo oluphantsi. Kwimibhobho ikakhulu idlala indima yokusika kunye ne-throttling. Inxalenye yokuvula kunye nokuvala i-valve ye-butterfly yombane yi-disc-shaped disc plate, ejikeleza i-90 degrees malunga ne-axis yayo kumzimba we-valve, ukuze ufezekise injongo yokuvula nokuvala okanye ukulungelelanisa. Ivalve yebhabhathane yokulungiswa kombane yahlulwe ngokwezi ndidi zilandelayo:
I-valve ye-butterfly yokulungiswa kombane (i-diameter encinci) : ineempawu ze-torque encinci yokuqala, umthamo omkhulu wokuhamba, ukulahleka kokuchasana kokuhamba okuncinci, ukusebenza okuguquguqukayo, njl.
Ivalve yebhabhathane yokulungiswa kombane, i-damper yokulungiswa kombane: ilungele i-metallurgical, imboni yokukhanya kunye namanye amashishini omlilo oqhumayo, isithando somlilo, isikhululo segesi kunye nezinye izihlandlo zokusebenza.
Ivalve yebhabhathane yokulungiswa kombane ye-NAC: Ivalve yebhabhathane yohlengahlengiso lombane ye-NAC ihambelana ne-JB/T8528-97 “Iimeko zobuGcisa zohlobo oluqhelekileyo lweSixhobo sombane sombane”.
Kukho iintlobo ezimbini zobonelelo lwamandla: 220V kunye ne-380V unikezelo lwamandla amanqanaba amathathu (abasebenzisi bangakhetha). Imveliso luhlobo lwangaphandle kwaye ibakala lokukhusela yi-IP67.
