4 Ufakelo
4.1 Ukulungiselela uFakelo
4.1.1 Phambi kofakelo lwevalvu, khangela ukuba isiqinisekiso sokufaneleka kwemveliso kunye nofakelo kunye nencwadana yokusebenza yesivalo siphelele kwaye siyasebenza.
4.1.2 Uhlolo lwenkangeleko luya kwenziwa phambi kofakelo lwevalvu, oluya kuthobelana nala malungiselelo alandelayo:
a) Umphezulu awuyi kuba neentanda, imingxunya yesanti, umonakalo womatshini, umhlwa, amabala kunye nezinye iziphene;
b) Ipleyiti yegama lomzi-mveliso ayisayi kuwa, kwaye iiparameters zokusebenza kwi-nameplate yomzi-mveliso ziyangqinelana neendawo eziphambili zoyilo lwesixokelelwano;
c) Amacala omabini evalvu kufuneka agcinwe enesigqubuthelo sokhuseleko.
d) Kufuneka kungabikho kugcinwa kwamanzi, umhlwa, amabala kunye nomonakalo kwibhodi yesekethe yeoli;
e) Akusayi kubakho peyinti kwiflange eqhagamshelweyo isikrufu, isikrufu siya kuhlala sicocekile, umphezulu wokutywina weflange awuyi konakaliswa ngumjelo wombhobho we-axial kunye nezinye izinto, kwaye isiphelo sewelding yombane siya kuba sinjalo, kwaye kuya kubakho. kungabikho umonakalo womatshini wokuwelda;
f) uhlobo lwevalve yokhuseleko lohlobo lwasentwasahlobo ukujonga ukuthembeka kwesitywina. Ivalve yodidi lwentonga kufuneka ibe nesixhobo sokubeka ihamile enzima;
g) Umphezulu ongaphakathi womzimba wombhobho werabha owenziwe ngerabha, iporcelain efakwe echibini kunye nevalve enemigca yeplastiki kufuneka igudiswe, i-lining kunye nesiseko sezinto kufuneka zidityaniswe ngokuqinileyo, ngaphandle kokuqhekeka, amaqhuma kunye nezinye iintsilelo.
4.1.3 Ukuhlolwa kweValve kunye nokuvalwa kovavanyo kunye novavanyo loxinzelelo
I-valve (ngaphandle kwevalve) iswitshi kufuneka ibe novakalelo, isalathisi sendawo sichanekile. Ngaphambi kofakelo, tshintsha ngesandla amandla evalve kathathu ukuze ubone ukuba kukho imeko yokuncamathela.
Ivalve (ngaphandle kwevalve) iyakuyekwa umzi-mveliso ngaphezulu konyaka omnye, kwaye kucetywa ukuba kwenziwe uvavanyo loxinzelelo phantsi kweemeko. Uvavanyo lwe-valve ye-petrochemical industry kunye nemimandla ehambelana nayo iya kwenziwa ngokuhambelana nemimiselo efanelekileyo ye-JB / T 9092, kunye novavanyo lwe-valve ye-industrial generally iya kwenziwa ngokuhambelana nemimiselo efanelekileyo ye-GB / T 13927.
4.2 Ukufakela
4.2.1 IiMfuno ngokuBanzi
4.2.1.1 Funda incwadi yofakelo ngononophelo phambi kokufaka ivalve.
4.2.1.2 Iivalvu ezibalulwe ukungena ngaphakathi ziya kufakwa ngokuhambelana neemfuno zevalvu.
4.2.1.3 Ngokubanzi, ivalve yokusonta akufuneki ifakwe ezantsi ukuthintela isitulo ukuba singagxunyekwa.
4.2.1.4 Ivalve yokukhangela yokuphakamisa kufuneka ifakwe kwinqanaba, i-swing check valve shaft sleeve kufuneka ibe kwinqanaba.
4.2.1.5 Kukho ivalve yesixhobo sokukhulula, kwaye ivelufa kufuneka iqulathe umbhobho ophumayo, kwaye ulwalathiso lokukhululwa akufuneki lujongane nomsebenzisi.
4.2.1.6 Indawo yofakelo ivelufa kufuneka ilungele ukusebenza kunye nokugcinwa kwayo.
I-actuating mechanism ibambekile ngenxa yokubola kwe-carbon steel torsion spring ekusetyenzisweni kwevalve elawula ubushushu obusebenza ngokwayo. Ingxaki yasonjululwa ngokutshintshwa kwemithombo ye-torsion ibe yintsimbi engenasici. (4) Kwimibhobho esetyenziswa kancinci, ezinye iinxalenye ziyaxinga ngenxa yokuba iivalvu ezisebenza ngokwazo azisebenzi ixesha elide. Ngokwenza ukugcinwa rhoqo kunye nokulinganisa i-valve, amathuba okuhluleka okuqhelekileyo ayancipha.
Imo yevalvu yokulawula ubushushu obusetyenziswayo ngokuzimeleyo
Ukuzimela ngokuzimeleyo iteknoloji yokulawula ivalve yesitshixo
(1) Ivalve yokulawula ubushushu (indawo yokubona ubushushu besakhiwo sangaphakathi) kwindawo yokutshintsha ubushushu kunye nolawulo lobushushu lokuphuma.
(2) Ivalve yokulawula ubushushu (indawo yokuva ubushushu yangaphandle yecapillari) kwindawo yokutshintsha ubushushu kunye nolawulo lobushushu obuphumayo.
2. Iingxaki zesicelo zenzekile
(1) I-spool ixingile;
(2) Ivalve ayinakuvulwa;
(3) i-capillaries efudumeleyo i-dehysis;
(4) I-activator ixingile;
(5) Ulwakhiwo lwangaphakathi lwe-activator ludliwe emva kwe-condensate;
(6) Ikhonkco elincinci le-activator alikwazi ukukhupha emva kokuba livaliwe;
(7) Ivalve evuzayo inkulu.
3 Ugcino kunye nokugcinwa kwamanyathelo
(1) Phambi kohlolo olufanelekileyo lonyaka, ukubakho kokusilela okuqhelekileyo kukhulu kakhulu. Ukwandisa amathuba okuhlola kulo nyaka. Umxholo wokuhlolwa kwalo nyaka kukuba: khangela ukuba kukho nayiphi na ingxaki kwinkqubo yokulungelelanisa, ukulungelelanisa ngesandla ubushushu, ukubona ukuba kukho indawo ehambelanayo yevalve yokulungisa; Khangela ukuvuza kwe-capillary.
(2) Ngenxa yokukhethwa kweglue ye-foam ukwenza ukufudumala kokushisa, okubangela ukuba i-foam glue ibe yi-valve, ukwenzela ukuba i-valve ibambelele. Emva kokutshintsha indlela yokushisa ukushisa, le ngxaki ixazululwa ngexesha.
(3) I-actuator ibambekile ngenxa yokubola kwe-carbon steel torsion spring. Ingxaki yasonjululwa ngokutshintshwa kwemithombo ye-torsion ibe yintsimbi engenasici.
(4) Kwimibhobho esetyenziswa kancinci, ezinye iinxalenye ziyaxinga ngenxa yokuba iivalvu ezisebenza ngokwazo azisebenzi ixesha elide. Ukugcinwa rhoqo kunye nokulinganisa kuqhutyelwa i-valve ukunciphisa amathuba okuhluleka okuqhelekileyo.
