Insimbi, i-alumina embonini yama-valve amacala okusebenza kwe-valve izingxenye zensimbi zokubukeka kwezidingo zekhwalithi

I-valve yebhola, i-globe valve, i-butterfly valve
Ukubunjwa kwensimbi kwamavalvu kuzohlolwa isekhondi ngemva kokugqokiswa nokusikwa, futhi kuzohlaziywa ukuthi azikho yini iziphambeko ezihlukahlukene endaweni ngokwezithombe ezishiwo kuleli zinga (bona Isahluko 4). Leli zinga liqoqa izinhlobo zeminyaka yobudala eyi-12 yokukhubazeka (bona 4.1–4.12, uhlobo ngalunye lwesici luhlanganisa amakesi angu-5 amelwe u-A, B, C, D kanye no-E. Zonke izinhlobo zokukhubazeka [uhlobo a} olukhanyayo c}} amatemu ezithombeni zokulinganisa zichaziwe. kuphela ngenxa yokukhubazeka okungaphezulu Izinhlobo nezici zokukhubazeka okuhlukahlukene kwendawo zichazwa kanje:
1 Ububanzi
Leli zinga licacisa izinhlobo nezici zokukhubazeka kwendawo kuma-valve, ama-flange, ukufakwa kwamapayipi nokunye ukucindezelwa kwensimbi.
Leli zinga lisebenza ekuhlolweni okubonakalayo nokwamukelwa kwekhwalithi engaphezulu yama-valve, ama-flange, ukufakwa kwamapayipi nokunye ukucindezelwa kwensimbi.
2. Ukuhlola izinga eliphezulu
Ama-castings ensimbi kufanele ahlolwe isekhondi ngemva kokulungiswa nokusikwa, futhi amaphutha ebusweni be-castings kufanele ahlolwe ngokuvumelana nezithombe ezichazwe kuleli zinga (bheka Isahluko 4).
3. Linganisa amazwibela esithombe
3.1 Leli zinga liqoqa izinhlobo zeminyaka eyi-12 yokukhubazeka okungaphezulu (bona 4.1–4.12), uhlobo ngalunye lwesici luhlanganisa izimo ezingu-5 ezimelwe u-A, B, C, D no-E, izimo ezimbili eziboniswe ngu-A no-B zamukelekile (zifanelekile), futhi izimo ezintathu ka-C, D kanye no-E amaphutha angamukelekile (angafaneleki). Uma kucatshangelwa izinkinga ezibangelwa ama-wax asebenzisa izinga elifanayo ukunquma usayizi wobubanzi bendawo yokulingisa, izithombe ezingu-60 ezinikezwe kuleli zinga ziyizibonelo zemidwebo yosayizi bangempela yanoma iyiphi indawo engu-4 X 100 mm X 125 mm yokulingisa okucacisiwe. phezulu.
3. 2 Zonke izinhlobo zokukhubazeka ezithombeni zokulinganisa [Thayipha a} ukukhanya c}} amatemu achazwa ukuthi asebenza kuphela kokonakala kwendawo. Izinhlobo nezici zesici ngasinye sobuso zichazwa kanje:
a} i-crack: ukuqhekeka okuqondile endaweni yensimbi ngenxa yesenzo sokucindezeleka kwangaphakathi nangaphandle. Ngokuvamile imifantu ebonakalayo ayifaneleki.
b) Imbobo yokushwabana: Ngenxa yensimbi}}L-1}}, ekuthelweni nasekusikeni kwesikhuphukeli sensimbi, umumo awujwayelekile ngokwedlulele, udonga lukhuni futhi kunezimbobo zekristalu ezinjenge-dendri.
C) Izimbobo zesihlabathi (slag): izimbobo ezinesanti (slag) ezakhiwe ebusweni bensimbi ngenxa yokubandakanyeka kwesihlabathi ensimbi encibilikisiwe.
d) Izimbotshana: ngenxa yengxube yegesi ensimbi encibilikisiwe, kanye nokwakheka kosayizi abahlukahlukene ebusweni be-skim l ", udonga lwembobo lubushelelezi futhi lunezimbobo ezimise okwepheya, eziyindilinga, ezisaqanda noma eziyizinaliti.
e (I-Ridged projection): I-spike (i-ridge) iphrojekshini yensimbi enomumo ongaphezulu kokusansimbi kwensimbi. Umumo wokusabalalisa okungajwayelekile kakhulu, okune-reticular noma okufana nomthambo wama-burrs abizwa ngokuthi imithambo.
f) Umsila wegundane: ama-indent angashoni (ngaphansi kuka-5~) anama-engeli ashubile akhiwa ebusweni be-skimmer ngenxa yokukhubazeka noma ukuguqulwa kwendawo yesihlabathi.
g) Ukuhlukaniswa okubandayo kanye nokuqhekeka: imifantu engena ngaphakathi noma engangeneki eyakhiwe phezu kwezinsimbi zokulingisa ngesimo samakhona ayindilinga ngenxa yokungaphelele kokuhlanganiswa kohlobo lomdanso. Ku-epidermis ngokuvamile enenethiwekhi ejulile yemisele ebizwa ngokuthi ama-creases.
h) Sika isibazi: insimbi ephonswe inqubo yokuhlanza, ukusika nokuthululwa, isikhuphukeli, ngenxa yokugqoka okungafanele kwesokunxele.
i) Isibazi: ama-protrusions ensimbi akhiwe ebusweni bensimbi anjengesibazi. Ingaphezulu limahhadlahhadla, unqenqema lubukhali, kukhona insimbi yethemba elizwakalayo elincane kanye nomzimba wensimbi oboshwe ozankosi uxhumekile, futhi kukhona ungqimba lwesihlabathi phakathi kwesibazi nokubunjwa.
j} Isibazi se-brace: Ishiywe phezu kwensimbi ephonswe ukwehluleka kwe-core brace noma i-inner chiller ukuncibilika ngokuphelele.
k) Isibazi sokushisela: ukulungiswa kokushisela kwezinsimbi zensimbi kushiywe ngenxa yokungalungiswa kahle ngemva kokushisela.
l) Indawo eqinile: ingaphezulu lensimbi ayibushelelezi futhi ayilingani.
