Isilinganiso Esijwayelekile Sokuklama kanye Nengcindezi

Le valve yeglobe yakhelwe ngokwezindinganiso ze-DIN njenge-DIN 3356 yokuklama ivalvu yeglobe kanye ne-DIN EN 1092-1 yobukhulu bokuphela okugoqekile. Isilinganiso sokucindezela se-PN16 sibonisa ingcindezi yokusebenza ephezulu evumelekile yebha engu-16 ekushiseni okuzungezile, ngemikhawulo yokucindezela-yokushisa echazwe yizindinganiso zezinto ze-DIN ne-EN ezisebenzayo. Idizayini ejwayelekile iqinisekisa ukuhambisana kobukhulu, ukushintshana, kanye nokusebenza okuthembekile ezinhlelweni zamapayipi zaseYurophu nezamazwe ngamazwe.

Ukwakhiwa Komzimba Nebhonethi

Umzimba we-valve kanye ne-bonnet kukhiqizwa ngensimbi engagqwali ye-ASTM A351 CF8, okulingana ne-EN 1.4308 (GX5CrNi19-10). Insimbi engagqwali ye-CF8 inikeza ukumelana okuhle kakhulu nokugqwala, amandla amahle okusebenza, kanye nokufaneleka ebangeni lokushisa elibanzi. Le nto iphumelela kakhulu ekuphatheni amanzi, umusi, uwoyela, amakhemikhali athambile, kanye noketshezi olubola kancane.

Ibhonethi ngokuvamile yenziwe ngebhawodi, inikeza ukugcinwa okuqinile kwengcindezi kanye nokufinyelela okulula kokunakekelwa. Indawo yokuvala eqondile phakathi komzimba nebhonethi, ehlanganiswe ne-gasket esezingeni eliphezulu, iqinisekisa ukuvalwa okuqinile kanye nokuqina kwesakhiwo kuyo yonke impilo ye-valve.

Umklamo Ovaliwe Wezimbongolo

Isici esiyinhloko sale valve ukuhlanganiswa kwayo kwe-bellows seal. I-bellows yensimbi ixhunyelwe esiqwini nasebhonethini, yakha uphawu olungenamoya oluhlukanisa ngokuphelele uketshezi lwenqubo emoyeni. Lo mklamo uqeda ukuvuza endaweni yokupakisha i-stem, okuyindawo evamile yokwehluleka kuma-valve e-globe avamile.

Ama-bellow avame ukwenziwa ngensimbi engagqwali enokwakhiwa okune-ply eminingi noma okwakhiwe ngendlela ehlanganisiwe, okuvumela ukuthi imelane nemijikelezo ephindaphindwayo yokuvula nokuvala ngaphandle kokwehluleka ukukhathala. Ukuze kuphephe kakhulu, i-valve ivame ukufakwa i-backup gland packing. Uma kwenzeka ukwehluleka kwama-bellow, ukupakisha kwesibili kuvimbela ukuvuza kwangaphandle, okuqinisekisa ukuqhubeka nokusebenza okuphephile.

Umklamo we-Stem, Disc, kanye ne-Seat

I-valve isebenza ngesimiso sokunyakaza okuqondile, lapho isiqu sihamba khona siqonde phezulu ukuze siphakamise noma sehlise idiski esihlalweni. Lokhu kulungiselelwa kunikeza ikhono elihle kakhulu lokugoba kanye nokulawula okunembile kokugeleza. Isiqu ngokuvamile senziwe ngensimbi engagqwali enokuphela okuhle kobuso ukuqinisekisa ukusebenza okubushelelezi nokuphila isikhathi eside kwenkonzo.

Idiski nesihlalo zenzelwe ukuvala okuqinile nokuqina. Ukwakhiwa okujwayelekile kunezihlalo zensimbi nensimbi, ezifanelekela amazinga okushisa aphezulu kanye nezinsizakalo zezimboni ezidinga kakhulu. Ukuze kube nokumelana nokuguguleka okuthuthukisiwe kanye nokusebenza kokuvala, izindawo zokuhlala zingase zibe nobuso obuqinile noma zimbozwe ngezinsimbi ezihambisanayo. I-geometry yevalvu yomhlaba ivumela ukusatshalaliswa kwamandla okuhlala okufanayo, okufaka isandla ekuvalekeni okuthembekile kanye nokuncipha kokuguguleka.

Ukuphela Kokuxhumana

Ivalvu yeglobhu evaliwe ye-DIN CF8 enesivalo ihlinzekwa ngeziphetho ezigobile ngokuhambisana ne-DIN EN 1092-1, PN16. Ukuxhumeka okugobile kunikeza ukufakwa okuphephile, okungenawo amanzi kanye nokulula kokususwa ukuze kuhlolwe noma kulungiswe. Ubukhulu bevalvu ubuso nobuso buvame ukuhambisana ne-DIN EN 558, okuqinisekisa ukuhambisana nezakhiwo zamapayipi ezikhona.

Izici Zokusebenza

Le valve yeglobe ivame ukusebenza ngesondo lesandla, inikeza ukusebenza okubushelelezi nokulawulwayo. Umklamo wesiqu okhuphukayo unikeza isibonakaliso esicacile sendawo yevalve, okuzuzisa ukuphepha kokusebenza kanye nokuhlela ukulungiswa. Ngenxa yephethini yayo yeglobe, ivalve yethula ukwehla kwengcindezi okuphezulu uma kuqhathaniswa namavalve esango, kodwa lokhu kuqhathaniswa nekhono layo eliphakeme lokulawula ukugeleza kanye nokuvala.

Ukwakhiwa okuvalwe nge-bellows kwenza leli valve lifaneleke kakhulu ekusetshenzisweni okuqukethe izinto ezinobuthi, ezivuthayo, noma ezibizayo, lapho ngisho nokuvuza okuncane kungenakubekezelelwa khona. Lifaneleka kahle nasezinhlelweni zikawoyela womusi kanye nowokushisa, lapho amazinga okushisa aphezulu angonakalisa ngokushesha izinto zokupakisha ezivamile.

Ukuhlolwa kanye nokuqinisekiswa kwekhwalithi

Ivalvu ngayinye ye-DIN yensimbi engagqwali ye-CF8 bellows evaliwe ye-DIN PN16 ihlolwa futhi ihlolwe ngokuqinile ngaphambi kokulethwa. Ukuhlolwa okujwayelekile kufaka phakathi ukuhlolwa kokucindezela kwegobolondo ukuqinisekisa ubuqotho bomzimba kanye nokuhlolwa kokuvuza kwesihlalo ukuqinisekisa ukusebenza kokuvala. Ukuhlanganiswa kwe-Bellows kuvame ukuhlolwa okwengeziwe komjikelezo nokuvuza ukuqinisekisa ukuthembeka kwesikhathi eside.

Izitifiketi zokuhlola izinto ezibonakalayo, imibiko yokuhlolwa kwengcindezi, kanye namarekhodi okuhlola ubukhulu ngokuvamile ayatholakala, okunikeza ukulandeleka okugcwele kanye nokuhambisana nezincazelo zephrojekthi.

Izicelo kanye nezinzuzo

Izicelo ezijwayelekile zifaka phakathi imigqa yokucubungula amakhemikhali, izinhlelo zomusi kanye ne-condensate, amayunithi okudlulisa ukushisa, izitshalo zemithi, kanye nezindawo zokucubungula ukudla. Izinzuzo ezibalulekile zaleli valve zifaka phakathi ukuvuza kwesiqu okungenalutho, ukumelana okuhle kakhulu nokugqwala, ukulawulwa okunembile kokugeleza, kanye nezidingo zokunakekelwa ezincishisiwe.
