Ikizamini cyumuvuduko wikizamini hamwe nuburyo bwo gukora valve akarere kagabana urutonde

Iyo umuyoboro ukoreshwa bwa mbere, hari umwanda w'imbere ,.indanga Irashobora gukingurwa gato, umuvuduko mwinshi wikigereranyo urashobora gukoreshwa mukuyihanagura, hanyuma ugafunga buhoro buhoro (ntabwo ufunze byihuse, ufunze bikabije, kugirango wirinde umwanda usigara udafunze hejuru yikimenyetso), wongere ufungure, usubiremo benshi inshuro, oza umwanda, hanyuma ushyire mubikorwa bisanzwe. Mubisanzwe fungura valve, hashobora kuba umwanda hejuru yikimenyetso. Mugihe cyo gufunga, uburyo bwavuzwe haruguru nabwo bugomba gukoreshwa kugirango bameshe neza, hanyuma bufunge kumugaragaro. Niba intoki nintoki byangiritse cyangwa byatakaye, bigomba guhita byuzuzwa, kandi ntibishobora gusimburwa namaboko yimuka yimuka, kugirango bitangiza kwangirika kwuruti, gufungura no gufunga ntabwo ari byiza, bikaviramo impanuka mubikorwa.
Uburyo bwo gukora bwa valve
Kuri valve, ntabwo igomba gusa kuba ishobora gushiraho no kubungabunga, ariko no gukora.
(a) intoki zifungura gufungura no gufunga
Intoki ni intoki ikoreshwa cyane, uruziga rwamaboko cyangwa ikiganza cyayo, yateguwe hakurikijwe abakozi basanzwe, urebye imbaraga zo hejuru zifunga nimbaraga zikenewe zo gufunga. Ntushobora rero gukoresha leveri ndende cyangwa umugozi muremure. Abantu bamwe bamenyereye gukoresha umugozi, bagomba kwitondera cyane, ntabwo ari imbaraga nyinshi, naho ubundi byoroshye kwangiza hejuru yikidodo, cyangwa isahani yamenetse uruziga rwamaboko, ikiganza.
Fungura kandi ufunge valve, imbaraga zigomba kuba zoroshye, ntabwo ari ingaruka. Ingaruka zimwe zo gufungura no gufunga ibice byumuvuduko mwinshi wibikoresho byazirikanye imbaraga zingaruka kandi valve rusange ntishobora gutegereza. Kuri valve yamashanyarazi, mbere yo gufungura, igomba gushyuha mbere kandi amazi yegeranye agomba kuvanwaho. Iyo ufunguye, bigomba gutinda bishoboka kugirango wirinde ikibazo cyo guhagarika amazi.
Iyo valve ifunguye neza, intoki zigomba guhindurwa gato, kugirango umugozi uri hagati, kugirango udahomba. Kububiko bwa pole-stem, ibuka umwanya wuruti iyo rufunguye rwose kandi rufunze byuzuye, kugirango wirinde gukubita hejuru yapfuye iyo ufunguye byuzuye. Kandi biroroshye kugenzura niba ari ibisanzwe iyo bifunze byuzuye. Niba valve iguye, cyangwa hagati yikimenyetso cya kashe yashyizwemo imyanda minini, umwanya wuruti uzahinduka mugihe ufunze byuzuye.
Iyo umuyoboro ukoreshejwe bwa mbere, habaho umwanda wimbere, valve irashobora gukingurwa gato, umuvuduko mwinshi wikigereranyo urashobora gukoreshwa mukwoza, hanyuma ugafunga gahoro gahoro (ntabwo ufunze byihuse, ufunze cyane, kugirango wirinde umwanda usigaye uva hejuru yikimenyetso), fungura nanone, usubiremo inshuro nyinshi, oza umwanda, hanyuma ushyire mubikorwa bisanzwe. Mubisanzwe fungura valve, hashobora kuba umwanda hejuru yikimenyetso. Mugihe cyo gufunga, uburyo bwavuzwe haruguru nabwo bugomba gukoreshwa kugirango bameshe neza, hanyuma bufunge kumugaragaro. Niba intoki nintoki byangiritse cyangwa byatakaye, bigomba guhita byuzuzwa, kandi ntibishobora gusimburwa namaboko yimuka yimuka, kugirango bitangiza kwangirika kwuruti, gufungura no gufunga ntabwo ari byiza, bikaviramo impanuka mubikorwa.
Bimwe mubiciriritse, gukonjesha nyuma ya valve ifunze, kugirango ibice bya valve bigabanuke, uyikoresha agomba kongera gufungwa mugihe gikwiye, kugirango ubuso bwa kashe budasiga ikidodo cyiza, bitabaye ibyo, uburyo buva kumurongo mwiza- umuvuduko wihuta, biroroshye gukaraba hejuru yikidodo. Mugihe cyo gukora, niba bigaragaye ko imikorere iruhije cyane, impamvu igomba gusesengurwa. Niba gupakira ari binini cyane, birashobora kuruhuka neza, nka valve stem skew, bigomba kumenyesha abakozi gusana. Imyanya imwe, muburyo bufunze, ibice bifunze bishyushye kwaguka, bikaviramo ingorane zo gufungura; Niba igomba gukingurwa muri iki gihe, igifuniko gishobora gukururwa igice cyuruziga kugeza kumuzingi kugirango ukureho imihangayiko, hanyuma isahani yo gutangira uruziga.
(2) Ibintu bikeneye kwitabwaho
1, 200 ℃ hejuru yubushyuhe bwo hejuru, kubera kwishyiriraho ubushyuhe bwicyumba, kandi nyuma yo gukoreshwa bisanzwe, kuzamuka kwubushyuhe, kwaguka kwinshi kwa bolt, kwiyongera kwicyuho, bityo rero bigomba kongera gukomera, byitwa "hot tight", abashoramari bagomba kubyitondera akazi, ubundi bikunda kumeneka.
2. Iyo ikirere gikonje, valve y'amazi igomba gufungwa igihe kirekire, kandi amazi agomba gukurwaho nyuma ya valve. Umuyoboro wamazi nyuma yumwuka, urashaka kandi gukuramo kondensate. Hasi ya valve ni silike kandi irashobora gukingurwa kugirango itwarwe.
3, ibyuma bitari ibyuma, bimwe bikomeye kandi bivunika, imbaraga nke, imikorere, gufungura no gufunga imbaraga ntibishobora kuba binini cyane, cyane cyane ntibishobora gukora imbaraga zikomeye. Witondere kandi kudakomanga ibintu.
4, mugihe hakoreshejwe valve nshya, gupakira ntibigomba gukanda cyane, kugirango bidatemba, kugirango bidatera igitutu cyane, kwihuta kwambara, kandi bigoye gufungura no gufunga.
Ikizamini cyumuvuduko wikizamini
Ikizamini cy'ingutu bivuga imbaraga z'umubiri. Ikizamini cyo kumeneka, bivuga ikimenyetso cyo gufunga hejuru yikizamini, ibi bizamini byombi ni ukugenzura imikorere nyamukuru ya valve. Ikigereranyo cyo gupima ni amazi asanzwe yubushyuhe, kandi kerosene irashobora gukoreshwa mumibande yingenzi. Umutekano wa valve uhoraho wikizamini, urashobora gukoresha azote gaze ihamye, irashobora kandi gukoresha umwuka cyangwa umwuka aho. Kububiko bwa diaphragm, gerageza numwuka.
(1) igitutu cy'ibizamini
Valve imbaraga zo kugerageza, kandi igitutu cyizina gifite isano ikurikira
Umuvuduko w'izina (Mpa) imbaraga zo gupima imbaraga (Mpa0.10.20.250.40.40.60.60.911.51.62.42.53.8466.49.610151624203025383248 ukoresheje igitutu kigaragara, nominal kuva 0.4 Mpa - 32 Mpa, Izi mbaraga zipima imbaraga ni 1.5 inshuro.
(2) Uburyo bwo kugerageza
Ikizamini cyingutu hamwe nikizamini gikorerwa ku ntebe yikizamini. Imiterere yintebe yikizamini (nkuko bigaragara ku gishushanyo cya 5-1) ni uko hari igice gikanda hejuru yintebe yikizamini hamwe numuyoboro uhujwe na pompe yikizamini munsi. Iyo valve imaze gukanda, pompe yipimisha ikora. Uhereye ku gipimo cyerekana umuvuduko wa pompe yikizamini, valve irashobora gusomwa umubare wumuvuduko. Iyo igeragezwa ryumuvuduko wuzuye amazi, umwuka uri muri valve ugomba gutwarwa. Isahani yumuvuduko mugice cyo hejuru cyintebe yikizamini ifite umwobo usohora kandi irakingurwa kandi ifunze hamwe na valve nto. Ikimenyetso cyerekana ko umwuka usukuye nuko amazi yose ava mumashanyarazi. Nyuma yo gufunga umuyaga, tangira kongera ingufu. Inzira yo kuzamura igomba kuba gahoro, ntabwo ityaye. Nyuma yo kugera kumuvuduko wateganijwe, komeza iminota 3, igitutu nticyujuje ibisabwa.
Uburyo bwikizamini cyo kumeneka gishobora kugabanywamo intambwe eshatu:
1, fungura inzira ya valve, wuzuze umwobo wa valve amazi (cyangwa kerosene), hanyuma wongere imbaraga kubisabwa kugirango ugerageze imbaraga, reba umubiri wa valve, igifuniko cya valve, gasketi, gupakira kumeneka.
2, funga umuhanda wa valve, igitutu kuruhande rumwe rwa valve kumuvuduko wizina, reba niba hari imyanda yaturutse kurundi ruhande.
3. Hindura valve hejuru hanyuma ugerageze kuruhande.
Valve mukarere kugabana urutonde rwibikorwa bya valve birenze iki?
Inshuti nyinshi zarayobewe kuruta kumenya icyo abakora kugirango babone indangagaciro, ikirango, aho ubuziranenge bumeze neza, abantu bamwe bavuze Shanghai, abantu bamwe bavuga Zhejiang, abantu bamwe bavuga Jiangsu, xiaobian muriyi modoka yubupfura.
Indangagaciro ziratandukanye kandi hariho ubwoko bwibarurishamibare buzwi bwa valve burenga ibihumbi umunani, kandi imwe 5 ntabwo ari imibare, ifite byinshi byabugenewe byabigenewe, bifite byinshi byateganijwe kumushinga runaka, ntabwo * * * bikoreshwa na isoko, ariko igice gito kivanyweho, burigihe tuvuga byinshi, ni akajagari, kuburyo bugaragara kugeza aho twe, Ibikurikira bikurikira ni inguni ya horizon, imibare yimisatsi yinka, gusura birambuye cyangwa gusura umurima, dukoreshe ibyiza (ibisobanuro birambuye byerekana ibirango n'ibiranga akarere nyamuneka witondere ingingo ikurikira). Hano hepfo tuzasesengura inganda zingenzi zikikije urutonde rwa valve no mugabane wisoko ryibisobanuro, amakuru ashingiye ku mibare y'Ikigo cy'igihugu gishinzwe ibarurishamibare (ababikora bafite impushya zo gukora, umubare w’ibicuruzwa n’ibisubizo by’imisoro ku mwaka).
