Ukufakwa kwe-valve eqhelekileyo ye-valves

A.Ukufakwa kwe-Palve yeSango

I-Palve yesangoKwakhona esabizwa njenge-valve yesango, ivali esebenzisa isango lokulawula ukuvulwa nokuvalwa, kwaye iguqula ukuhamba kwepayipile kwaye ivula kwaye ivale i-Pipeline ngokutshintsha icandelo lomnqamlezo.I-valves yesango Zisetyenziselwa kakhulu imibhobho evulekileyo okanye ivale ngokupheleleyo i-fluid wine. Ukufakwa kwe-Palve yeSango akunakubakho mfuneko yesalathiso, kodwa ayinakubhalwa.

B.Ufakelo lweiglobhu ivalve

Ivalve ye-globe yivali esebenzisa i-valve disc ukulawula ukuvulwa nokuvalwa. Lungisa ukuhamba okuphakathi okanye ukunqunyulwa kwindinyana ephakathi ngokutshintsha umsantsa phakathi kwediski ye-valve kunye nesitulo sevali, oko kukuthi, ukutshintsha ubungakanani becandelo lesitishi. Xa ufaka ivalve evalelweyo, ingqalelo kufuneka ihlawulwe kwindlela yokuhamba kwe-flweid.

Umgaqo ekufuneka ulandelwe xa ufaka i-valve globec kukuba ulwelo kwi-pipew luhamba ngomngxunya we-valve ukusuka ezantsi ukuya phezulu, iphantsi 'kwaye ayivumelekanga ukuyifaka ngasemva.

C.Ukufakelwa kweValve yokujonga

Jonga i-valve, ekwabizwa ngokuba yivalve yokujonga kunye ne-valve enye, yivali evula ngokuzenzekelayo kwaye ivale phantsi kwesenzo sobume boxinzelelo phakathi kwevalve engaphambili. Umsebenzi wayo kukwenza ukuhamba okuphakathi kwendlela enye kuphela kwaye kuthintele iphakathi ukusuka ekuhambeni kwendlela yokubuyela kwicala lokubuyela umva. Ngokwemibutho yabo eyahlukeneyo,Jonga i-valveves Faka uhlobo lokuphakamisa, uhlobo lokutshisa kunye nebhabhathane. Ukuphakamisa iValve yahlulwe yaba luthe tye kwaye luthe nkqo. Xa ufaka iJonga i-valve, ingqalelo kufuneka ihlawulwe kukhokelela ekuhambeni kwendlela kwaye ayinakufakwa ekubuyiselweni.

D.Ukufakwa koxinzelelo ukunciphisa ivalve

Ivali yokunciphisa uxinzelelo yivali elinciphisa uxinzelelo lwe-inlet kwingcinezelo ethile efunekayo ngokuhlengahlengiswa, kwaye ixhomekeke kumandla e-PHERHE ngokuzenzekelayo igcina ngokuzenzekelayo inyanzeliseke ngokuzenzekelayo.

1. Iqela loXwongelo lokuChintela iValve lifakwe ngokuthe nkqo lusetwe eludongeni kwindawo efanelekileyo emhlabeni; Isibonelelo sokunciphisa i-Valve Valve esifakiweyo ngokuthe tyaba ngokubanzi sifakwe kwiqonga lokusebenza ngokusisigxina.

2. Isitya sokusebenza silayishwe eludongeni ngaphandle kweevalves ezimbini zolawulo (zihlala zisetyenziselwa i-vallves) ukwenza i-blocket, kwaye umbhobho we-Bypass unamathele kwinqanaba kunye nokulungelelaniswa.

3. Ivali yokunciphisa uxinzelelo kufuneka ifakwe ngokuthe tye kumbhobho othe tye, kwaye akufuneki ityekelwe. Utolo kwi-veli umzimba kufuneka lukhombe kwicala lokuhamba okuphakathi, kwaye akufuneki ifakwe ngasemva.

I-4. I-Globe Bulves kunye ne-Globe Bigs ye-Globe Gaugs yoxinzelelo kufuneka ifakwe kumacala omabini ukujonga uxinzelelo olutshintsha ngaphambi nasemva kwevalve. Ububanzi bombhobho ongemva kwevalve yokunciphisa uxinzelelo kufuneka ibe yi-2 # -3 # inkulu kune-poile pile pile phambi kwevalve ye-Inlet PAIRE, kwaye umbhobho we-Bypass kufuneka afakwe kulondolozo.

5. Ingcinezelo yokunyanzelwa kombhobho we-membrane uxinzelelo lweValve kufuneka iqhagamshelwe kumbhobho woxinzelelo ophantsi. Imibhobho yoxinzelelo esezantsi kufuneka ixhotyiswe ngamandla okhuseleko ukuqinisekisa ukusebenza ngokukhuselekileyo kwale nkqubo.

I-6. Xa isetyenziselwa i-steam decompic, umbhobho wokuphelisa kufuneka usekwe. Ngeenkqubo zemibhobho efuna inqanaba eliphezulu lokucocwa, isihluzo kufuneka sifakwe phambi koxinzelelo lokunciphisa ivalve encipha.

7. Emva kokufakwa koxinzelelo lwe-Voveve ifakiwe, ivalve yokunciphisa uxinzelelo kunye nevalve encitshisiweyo kufuneka ihlolwe, kwaye igqitywe kwaye ilungiswe ngokweemfuno zoyilo, kwaye kufuneka yenziwe ngolungelelwaniso.

8. Xa usandul 'ukugungxula ivalve enciphisa ivalve enciphayo, vala ivalve ye-inlet yoxinzelelo kwaye uvule ivalve egudileyo yokufunxa.

E.Ukufakwa kwemigibe

Umsebenzi osisiseko we-Steam Trap kukukhupha amanzi acocekileyo, umoya kunye ne-carbon diokside kwinkqubo ye-Steam ngokukhawuleza; Kwangelo xesha, inokuthintela ngokuzenzekelayo ukuvuza kwe-steam ukuya kuthi ga kwinqanaba elikhulu. Zininzi iintlobo zemigibe, nganye inomsebenzi owahlukileyo.

I-1. Vala i-valves evaliweyo (i-valves) kufuneka isetiwe ngaphambi nasemva, kwaye isihluzo kufuneka sibekwe phakathi komgibe kunye ne-valve engaphambili yokuthintela ubumdaka kumanzi aqinisekisiweyo ukusuka ekuthinteleni umgibe.

2. Umbhobho wokuhlola kufuneka ufakwe phakathi komgibe we-steam kunye ne-valve engasemva ivaliwe ukuze ujonge ukuba ingaba i-steam isebenza ngesiqhelo. Ukuba isixa esikhulu se-Steam sikhutshiwe xa kuvulwa umbhobho wokuhlola, kuthetha ukuba umgibe we-steam waphukile kwaye kufuneka alungiswe.

3. Injongo yokubeka umbhobho we-Bypass kukukhupha isixa esikhulu samanzi ancitshisiweyo ngexesha lokuqalisa kunye nokunciphisa umthwalo wombala wetrayi.

4. Xa umgibe usetyenziselwa ukukhulula amanzi acocekileyo esixhobo sokufudumeza, kufuneka ifakwe kwinxalenye engezantsi yezixhobo zokufudumeza, ukuze umbhobho otshisiweyo abuyiselwe nkqo ukuba agcinwe kwizixhobo zokufudumeza.

I-5. Indawo yokufakelwa kufuneka ikufuphi nendawo ye-drain kangangoko kunokwenzeka. Ukuba umgama kude kakhulu, umoya okanye i-steam iya kuqokelela kumbhobho omncinci phambi komgibe.

I-6. Xa umbhobho othe tyaba wombhobho ophambili we-steam kude kakhulu, ingxaki yengxaki kufuneka ithathelwe ingqalelo.

F.Ukufakwa kweValve Envelo

Ivalve yokhuseleko yi-valve ekhethekileyo yokuba iindawo zokuvula kunye nokuvala zikwimeko evaliweyo evaliweyo phantsi kwesenzo samandla angaphandle. Xa uxinzelelo lwendawo yendawo okanye i-pipeline inyuka ngaphaya kwexabiso elichaziweyo, iyayikhupha ngaphandle kwenkqubo yokuthintela uxinzelelo oluphakathi kumbhobho okanye izixhobo ezivela kwixabiso eliphezulu. .

1. Ngaphambi kofakelo, imveliso kufuneka ihlolwe ngononophelo ukuqinisekisa ukuba ingaba kukho isatifikethi sokungqinelana nencwadi yemveliso, ukuze icacisa uxinzelelo oluqhubekayo xa lishiya umzi-mveliso xa ushiya umzi-mveliso xa eshiya umzi-mveliso xa eshiya umzi-mveliso xa eshiya umzi-mveliso.

2. Ivalve yokhuseleko kufuneka icwangciswe kufutshane kangangoko kunokwenzeka kwiqonga lokuhlolwa kunye nokugcinwa.

3. Ivalve yokhuseleko kufuneka ifakwe ngokuthe nkqo, i-medium kufuneka iphume ezantsi ukuya phezulu, kwaye i-verication ye-vave itshekishwe.

4. Phantsi kweemeko eziqhelekileyo, iivalves ezivaliweyo azinakusetwa ngaphambi nasemva kwevali yokhuseleko yokuqinisekisa ukhuseleko kunye nokuthembeka.

5. Uncedo lweValve Elveve Xa i-Medium yirhasi, ikhutshelwe ngokubanzi kwimozulu yangaphandle;

I-6. I-oyile kunye negesi ephakathi inokuthi ikhutshwe emoyeni, kwaye i-Outlet yoMbhobho weValve yeValve i-3M kufuneka ibe ngaphezulu kweyona candelo liphezulu, kodwa ezi meko zilandelayo kufuneka zikhutshwe kwinkqubo evaliweyo yokuqinisekisa ukhuseleko.

I-7. Ububanzi bombhobho wabantu kufuneka bube nokulingana kububanzi bombhobho wevali; Ububanzi bombhobho wokukhupha akufuneki bube mncinci kune-valet yevali, kwaye umbhobho wokukhupha kufuneka ukhokelwe ngaphandle kwaye ufakwe i-elbow yendawo ekhuselekileyo.

8. Xa kufakwe ivalve yokhuseleko, xa unxibelelwano phakathi kwevalve ekhuselekileyo kunye nezixhobo zivula i-Ilding, i-Depleter yoLwimi kufuneka ilingane nobukhulu beendawo ezinqabileyo.
