Njengevalve enomsebenzi obalulekileyo wokukhusela,ivalve yokhuselekoisetyenziswa ngokubanzi kwiinqanawa ezahlukeneyo zoxinzelelo kunye neenkqubo zombhobho, ezinokuvulwa ngokuzenzekelayo xa inkqubo ifikelela kumda ophezulu wexabiso elichaziweyo loxinzelelo Ukukhupha i-medium engaphezulu ngaphandle kwenkqubo, kwaye emva kokukhutshwa kunokuvalwa ngokuzenzekelayo ukuqinisekisa ukuba inqanawa yoxinzelelo inokukhuseleka, uxinzelelo oluthembekileyo oluvunyelwe ukuba lusebenze ngaphakathi komda ukunqanda iingozi ezinkulu zokhuseleko.

Njengomvelisi wevalvu yokhuseleko, i-COVNA izibophelele ekukuncedeni ukuba ukhethe kwaye wenze ivalvu yokhuseleko oyifunayo.Qhagamshelana nathi ngesisombululo sevalve sasimahla ngexabiso elifanelekileyo.

● Ubungakanani bobungakanani: DN20 ukuya kwi-DN400

● Max.Uxinzelelo: 60 bar.Ukuba ufuna uxinzelelo oluphezulu, nceda uqhagamshelane nathi.

Ukusebenza okuqhelekileyo kwevalve yokukhusela akuhambelani kuphela nokusetyenziswa okukhuselekileyo okuqhelekileyo kweenqanawa zoxinzelelo ezifana neebhoyili kodwa zihambelana ngqo nokhuseleko lobomi babantu kunye neepropati.Ngoko ke, ingqwalasela enkulu kufuneka ihlawulwe kwiintsilelo eziqhelekileyo ze-Boiler Safety Valve kwaye ziphelise ngexesha elifanelekileyo.

1. IValve yoKhuseleko iyavuza

Ukuvuza kwevalve yenye yezona mpazamo zixhaphakileyo zevalve yokhuseleko lwebhoyila.Ibhekisa ikakhulu ekuvuzeni phakathi kwediski yevalvu kunye nesitulo sevalvu phantsi koxinzelelo oluqhelekileyo lokusebenza.

Izizathu zokusilela kunye nezisombululo zabo:

1.1Ukungcola kuwela kumphezulu wokutywina.Sebenzisa isitshisi sokuphakamisa ukuvula ivalve amaxesha amaninzi ukukhupha ubumdaka.

1.2Vala umonakalo womphezulu.Ngokwezinga lomonakalo, indlela yokugaya okanye ukugaya emva kokujika kufuneka isetyenziswe ukulungisa.Emva kokulungiswa kufuneka kuqinisekiswe ukutywinwa komphezulu wokutyibilika, ukuguda kwayo akufanele kube ngaphantsi kwe-10.

1.3Ngenxa yendibano engafanelekanga okanye umthwalo wombhobho, ukugxila kwamacandelo kutshatyalaliswa.Imithwalo eyongezelelweyo yombhobho iya kuhlanganiswa kwakhona okanye ingabandakanywa.

1.4Uxinzelelo lokuvula i-valve lusondele kakhulu kuxinzelelo oluqhelekileyo lwezixhobo, ukwenzela ukuba indawo yokutywina iphantsi kunoxinzelelo.Xa ivalve iphantsi kokungcangcazela okanye ukuguquguquka koxinzelelo oluphakathi, ithanda ukuvuza.Uxinzelelo lokuvula kufuneka luhlengahlengiswe ngokwemeko yamandla yesixhobo.

1.5I-Lose Spring Yehlisa uxinzelelo lokumisela kwaye ibangele ukuvuza kwevalvu.Ngamana Kuba ngenxa yobushushu obuphezulu okanye ukubola kunye nezinye izizathu, kufuneka kuthathwe ukutshintsha intwasahlobo, okanye utshintshe ivalve kunye namanye amanyathelo.Ukuba kubangelwa ummiselo ongafanelekanga, i-screw yokulungelelanisa inokuqiniswa ngokufanelekileyo.

2. Uxinzelelo oluphantsi lokuBuyisa kweValve yoKhuseleko

Isizathu 1:Uxinzelelo lwe-Low Return luya kubangela ukuba inani elikhulu eliphakathi likhuphe ngokuhamba kwexesha, okubangela ukulahlekelwa kwamandla okungadingekile.Isizathu sesokuba ivalve yokunceda i-spring pulse kumthamo omkhulu wokukhutshwa komphunga, olu hlobo lwevalvu yokuphefumla ukuvula, i-medium iyaqhubeka nokuphuma, i-vibration relief valve body, okanye ivalve yokuphefumla ngaphambi nasemva kwamandla Ukukhutshwa kwevalve ephakathi akwanelanga ukuqhubeka nokunyuka, ngoko ke umphunga okwityhubhu ye-pulse ecaleni kwentloko yerhasi yomgqomo uyaqhubeka nokuqukuqela intshukumo yevalvu yokuphefumla.

Kwelinye icala ngenxa yolu hlobo lwentshukumo yokhuseleko lwevalve yentshukumo yevalve yokhuseleko.Ukulungelelaniswa kwayo kwakhona ukwenza indawo yoxinzelelo lwe-kinetic, i-spool iya kuphakanyiswa, ukwenzela ukuba i-valve yokukhusela i-impulse iqhubeke nokuphuma, ukukhutshwa okukhulu kwe-steam, indima ye-spool ekukhuseleni kwe-thrust enkulu, ukhuseleko lwe-impulse. ivelufa kuya kuba lula ukubuyela esitulweni.

Isisombululo 1:Okwangoku, indlela yokuphelisa impazamo kukuvala i-valve ye-throttle encinci, ukwenzela ukuba ukuhamba kwe-medium ngaphandle kwe-valve yokunceda ukunciphisa uxinzelelo kwindawo yoxinzelelo lwamandla e-kinetic, ukwenzela ukuba i-valve yokukhupha i-valve ibuyele kwi-valve. isihlalo.

Unobangela 2:Isizathu sesibini esibangela ukubuyiswa kwengcinezelo ephantsi kukuba imvume ehambelanayo phakathi kwe-spool kunye ne-sleeve yesikhokelo ayifanelekanga, kwaye i-fit clearance yithuba elincinci lokubuya lokulibaziseka.

Isisombululo 2:Indlela yokuphelisa olu kusilela kukukhangela ngononophelo ubungakanani be-spool kwakhona isikhokelo sendawo yomkhono, kunye nomsantsa omncinci kakhulu, ukunciphisa isigqubuthelo sediski ngokuthe ngqo okanye idiskhi yokumisa i-valve ububanzi okanye ukwandisa i-disc kunye nesikhokelo se-sleeve gap radial, ukwandisa indawo yokujikeleza kwenxalenye, ukwenzela ukuba ukuhamba komphunga kungaphambukiswa xa uxinzelelo lwengingqi lwenza indawo yoxinzelelo lwekinetic ephezulu.

3. Ukuvuza okudibeneyo koMzimba

Ukuvuza komphezulu odityanisiweyo wevalve kubhekisa ikakhulu kumphezulu nasezantsi wevalve umphezulu wokuvuza.

Izizathu zokusilela kunye nezisombululo zabo:

Isizathu 1:Omnye ngumphezulu odityanisiweyo we-bolt force force ayonelanga okanye uqine kancinci, okukhokelela kumphezulu ombi wokudityaniswa kwetywina.
Isisombululo 1:Indlela yokuphelisa kukulungelelanisa ibholithi yokuqinisa amandla, kwibholiti eqinileyo kufuneka ibanjwe ngokuhambelana nendlela yokuqinisa i-diagonal, kungcono ukulinganisa yonke i-side side clearance, i-bolt iqinile ukuba ingahambi ukuza kuthi ga ngoku, kwaye wenze. ukucocwa komphezulu odibeneyo kuzo zonke iindawo ezihambelanayo.

Unobangela 2:Okwesibini, i-valve yomzimba we-joint surface ye-tooth seal gasket ayihambelani nomgangatho.Oku kubangela ukuba umdibaniso womzimba wevalvu uvuze.
Isisombululo 2:Ukugcinwa komgangatho we-spare parts, ukusetyenziswa kwe-gasket eqhelekileyo efana nezinyo kunokuphepha le nto.

Isizathu 3:Okokugqibela, yivalve umzimba wendiza edibeneyo ihlwempuzekile kakhulu okanye ngokusilela kwetywina lokutywinwa komcamelo wokungacoceki.
Isisombululo 3:Ukupheliswa kokuvuza komphezulu womzimba ngenxa yokungafihli kakuhle komphezulu womzimba kukuqhawula ivalve kwaye ubuye usila umphezulu odibeneyo de ube udibana nemigangatho yomgangatho.Ukuba isitywina asiphumeleli ngenxa yokupakishwa kokungcola, coca ngokucophelela indawo edibeneyo ukuze ugweme ukungcola okuwela kwi-valve assembly.

4. Ivalve yokuNceda ilibazise ukuBuyisa

Umsebenzi ophambili wevalve yokunceda emva kokubuya kwevalve ephambili ilibazisekile ixesha lokubuya likhulu kakhulu.

Izizathu zokusilela kunye nezisombululo zabo:

Isizathu 1:Kwelinye icala, ukuvuza kwegumbi lepiston yevalve enkulu yokunceda inkulu.
Isisombululo 1:Indlela yokuphelisa olu hlobo lwenkathazo isonjululwa ngokuvula ivalve ye-throttle banzi kunye nokwandisa i-diameter ye-throttle hole.

Isizathu 2:Ngakolunye uhlangothi, ukungqubuzana phakathi kweendawo ezihambayo kunye neendawo zokulungisa i-valve yokhuseleko oluphambili luya kubangela ukuba i-valve ekhuselekileyo yokukhusela ibuyele esihlalweni ngokukhawuleza.
Isisombululo 2:Isisombululo sale ngxaki kukulingana eyona ndawo iphambili yevalve yokunceda kunye neendawo ezizinzileyo ngaphakathi koluhlu oluqhelekileyo lwekhonsoli yokucoca.

5. Ingxoxo yeValve yoNcedo

Isenzeko sokungcangcazela kwevalve yokhuseleko kwinkqubo yokukhupha ibizwa ngokuba yingxoxo yevalve yokhuseleko.Into yokuncokola yenza lula ukudinwa kwesinyithi, okunciphisa ukusebenza koomatshini beValve yoKhuseleko kwaye ibangele ingxaki enkulu efihliweyo yezixhobo.

Izizathu zokusilela kunye nezisombululo zabo:

Isizathu 1:Ngakolunye uhlangothi, i-valve isetyenziswe ngokungafanelekanga, umthamo wokukhupha i-valve inkulu kakhulu.
Isisombululo 1:Indlela yokuphelisa kukuba ukukhutshwa okulinganiselwe kwe-valve kufuneka kusetyenziswe ngokusondeleyo kangangoko kunokwenzeka ukukhutshwa okufunekayo kwesixhobo.

Unobangela 2:Ngakolunye uhlangothi, ngenxa yokuba ububanzi bombhobho wokungena buncinci kakhulu, buncinci kunobubanzi bokungena kwevalve, okanye ukuchasana kombhobho wokungena kukhulu kakhulu.
Isisombululo 2:Indlela yokuphelisa xa i-valve ifakwe, ububanzi bangaphakathi bombhobho wokungena akufanele bube ngaphantsi kwe-inlet ye-valve okanye ukuchasana kombhobho wokungena kufuneka kuncitshiswe. Oku kunokusombulula ngokunciphisa ukuchasana kokuphuma umgca.

Nayiphi na imfuno okanye ingxaki yevalve yokhuseleko, nceda uqhagamshelane nathi kwaye siya kukuvuyela ukukunceda ukuyisombulula.
