Imirongo itanu yo gusaba hamwe nibyiza byo gushyingura umupira wa valve amabwiriza ya ball valve

Imirima itanu yo gusaba hamwe nibyiza byo gushyingura umupira wamabuye amabwiriza yumupira wumupira wuzuye Amashanyarazi yo gusudira umupira wuzuye kubikoresho bitandukanye byubukanishi: umuyoboro utandukanye wo gutunganya ubushyuhe, umusaruro utandukanye winganda zikora gazi zamazi hamwe nu miyoboro yo gushyushya. Gushyingura umupira wa valve inshuro ebyiri gucomeka no gusohora koresha torsion isoko ya torque ihindagurika, ntanubwo valve yaba iri kumugaragaro cyangwa ifunze, intebe yo hejuru, hagati no hepfo yintebe ikora inzitizi y'amazi, isahani yinzira ya peteroli mukugumana kwa cavite ukurikije valve isohoka metabolism. Ingaruka yumuvuduko wumubyigano wumupira ushyinguwe urashobora gutuma ubushyuhe bwibikoresho byo kugumana impyiko bwiyongera kandi bigatera ihinduka ryumuvuduko udasanzwe, bitabaye ngombwa ko wishingikiriza kuri valve, kandi imikorere yintebe irashobora guhita yorohereza umuvuduko ukabije, bizabikora menya neza umutekano wa valve mugutwara ibintu byamazi ni ngombwa cyane. 1, amashanyarazi yuzuye yo gusudira umupira wa gazi yo mumujyi: umuyoboro wa gazi wohereza ibicuruzwa hanze, umuhanda munini na buri shami rishinzwe gutanga amasoko, nibindi 2, gushyushya hagati: ibikoresho byo gushyushya ibikoresho binini kandi biciriritse byohereza ibicuruzwa hanze, umuhanda munini, imirimo kuruhande. 3, amashanyarazi yuzuye yo gusudira umupira wa valve kugirango uhindure ubushyuhe: umuyoboro hamwe nu mugenzuzi wo gufungura no gufunga. 4. 5, amashanyarazi yuzuye yo gusudira umupira wibikoresho bitandukanye byubukanishi: imiyoboro itandukanye yo gutunganya ubushyuhe, umusaruro winganda zitandukanye za gaze ya gazi yamazi hamwe nu miyoboro yo gushyushya. Gushyingura umupira wa valve inshuro ebyiri gucomeka no gusohora koresha torsion isoko ya torque ihindagurika, ntanubwo valve yaba iri kumugaragaro cyangwa ifunze, intebe yo hejuru, hagati no hepfo yintebe ikora inzitizi y'amazi, isahani yinzira ya peteroli mukugumana kwa cavite ukurikije valve isohoka metabolism. Ingaruka yumuvuduko wumubyigano wumupira ushyinguwe urashobora gutuma ubushyuhe bwibikoresho byo kugumana impyiko bwiyongera kandi bigatera ihinduka ryumuvuduko udasanzwe, bitabaye ngombwa ko wishingikiriza kuri valve, kandi imikorere yintebe irashobora guhita yorohereza umuvuduko ukabije, bizabikora menya neza umutekano wa valve mugutwara ibintu byamazi ni ngombwa cyane. Ibyiza byumupira washyinguwe 1, gufunga gutabara amavuta yihutirwa: kubera ibintu byanduye mubintu cyangwa impanuka zumuriro biganisha ku gutungurwa gutunguranye kwintebe ya valve, valve yamavuta izana isano hagati yo gutera amavuta, pompe yatumijwe mu mahanga itwara igihe kandi imbaraga zo gutera amavuta yo gufunga mumwanya wo gufunga intebe, kugabanya kumeneka. 2. Ikirangantego cyizewe gifunga kashe hamwe na torque ikora cyane: usibye gushyirwaho impeta yerekana ibimenyetso bifatika, O-impeta yongewe kumutwe wapakira, gufunga inzira ebyiri byemeza ko kashe ya valve ihagaze neza; Kwiyongera kwinshi kwa grafite gupakira no gufunga amavuta bituma igiti kiva nyuma yumuriro muke cyane. Kuzunguruka kw'ibiti hamwe no gusunika bituma valve yoroshye gukora. 3. Diameter yuzuye cyangwa diameter yagabanutse: Umuyoboro wuzuye wa diameter cyangwa kugabanya imiterere ya diameter birashobora gukoreshwa ukurikije uko ibintu bimeze. Igiteranyo cyuzuye cya diametre yuzuye ya diameter yuzuye ihuye na diameter nominal yumuyoboro, ifasha gusukura imiyoboro. 4, uruti rwa valve rushobora kwagurwa: ukurikije ibikenewe byo guterana cyangwa gukora, uruti rwa valve rushobora kwagurwa. Umuyoboro mugari wa ball ball, cyane cyane ukwiranye na gaze yo mumijyi nahandi hantu hagomba gushyingurwa mu buryo butaziguye imiyoboro ya kaburimbo. Kwagura valve stem ibisobanuro nkuko bisabwa nabakiriya. 5. Biroroshye gukora: intebe ya valve hamwe nigiti kizunguruka gifite imbaraga zo kurwanya friction hamwe no kwisiga neza byatoranijwe kugirango bigabanye umuriro wimikorere ya valve. Kubwibyo, imipira yashyinguwe irashobora gukora kuburyo bworoshye kuri valve igihe kirekire nubwo idatanga amavuta yo gufunga. Igikoresho cyo kugenzura intoki hamwe na rocker cyangwa ibikoresho, amashanyarazi cyangwa pneumatike yumupira utwarwa nigikoresho cyamashanyarazi cyangwa igikoresho cya pneumatike, kora umupira kuzunguruka 90. Fungura cyangwa ufunge valve. Ukuboko - gukoreshwa umupira wa valve uruti hejuru. Concave groove azimuth hamwe nuburebure bwicyerekezo cyizunguruka nicyerekezo cyumuyoboro utemba urakinguye, kandi icyerekezo gihagaritse cyibicuruzwa byafunzwe. Ububiko bwigihe kirekire bwo kubika bugomba kubungabungwa buri gihe, *** imyanda. Ugomba kwitondera gusukura hejuru, ukirinda kwangirika kwubuso. Mbere yubwubatsi kugirango ugenzure umuyoboro wa valve nubuso, niba hari ikizinga, ugomba guhitamo guhanagura neza. Intambwe ya 1: Icyiciro Aya mabwiriza akubiyemo diameter nominal DN15mm ~ 500mm (1/2 "~ 20"), diameter nominal PN1.6MPa ~ 10MPa (ANSI> 2. Ibyingenzi bikoresha 2.1 Urufunguzo rukoreshwa mugukingura cyangwa gufunga imiyoboro n'imashini. 2.2 Koresha ibikoresho bya valve ukurikije ibikoresho. 2.2.1 130 fiber Ikirahuri cya PTFE ≤160 ℃ PPL (admixture polystyrene) ≤300 ℃ Intambwe ya 3: Imiterere 3.1 Imiterere yimipira yumupira irerekanwa mumashusho 1 3.2 Ibice bikoreshwa bifunga gasketi, gupakira PTFE cyangwa igishushanyo cyoroshye, kashe yizewe 4.1 Igikoresho cyo kugenzura intoki koresha ibikoresho byohereza ibyuma cyangwa ibikoresho, amashanyarazi cyangwa pneumatike umupira utwarwa nigikoresho cyamashanyarazi cyangwa igikoresho cya pneumatike, kugirango umupira uzunguruke 90. Fungura cyangwa ufunge valve 4.2 Intoki zumupira wintoki hejuru yometse kumurongo wa concave groove azimuth na uburebure bwicyerekezo cyizunguruka nicyerekezo cyumuyoboro utemba urakinguye, kandi icyerekezo gihagaritse cyibicuruzwa byafunzwe. 4.3 Gufungura no gufunga ibimenyetso byumupira wumuriro na pneumatike birangwa nicyerekezo cyumwanya mubikoresho byamashanyarazi nigikoresho cya pneumatike. 5. Kubika, kubungabunga, gushiraho no kubishyira mu bikorwa 5.1 Umuyoboro ugomba kubikwa mucyumba cyumye, gihumeka. Impande zombi zumutekano wumuhanda zigomba guhagarikwa. 5.2 Ububiko bwigihe kirekire bwo kubika bugomba kubungabungwa buri gihe, imyanda. Ugomba kwitondera gusukura hejuru, ukirinda kwangirika kwubuso. 5.3 Mbere yo kubaka, genzura neza niba ikimenyetso cya valve gihuye nibisabwa gukoreshwa. 5.4 Mbere yo kubaka, reba umuyoboro wa valve n'ubuso. Niba hari ikizinga, kwoza ukoresheje igitambaro cyoza. 5.5 Reba niba gupakira byafunzwe mbere yo kubaka, kandi urebe neza ko gupakira. Mugihe kimwe, kuzenguruka kuruti rwa valve ntibishobora gukumirwa. 5.6 Indangagaciro zigomba kuba zifunguye neza nyuma yo kurangiza kwishyiriraho sisitemu cyangwa ikizamini cya hydrostatike. 5.7 Umupira ugomba gukingurwa cyangwa gufungwa mbere yo gukoreshwa, kandi igice cyumupira ntigomba gufungurwa kugirango uhindure valve. 5.8 Mugihe cyo gufungura cyangwa gufunga valve yintoki, rocker igomba gukoreshwa mugukingura cyangwa kuyifunga, kandi infashanyo yimari cyangwa ibindi bikoresho ntigomba gukoreshwa. 5.9 Gusaba Valve bigomba kubungabungwa buri gihe kugirango harebwe niba hari ibyangiritse hejuru no gupakira gasike. Niba ibyangiritse bitemewe, bigomba gusanwa no gusimburwa mugihe. 5
