Intoki zifungura gufungura no gufunga, imbaraga zikabije
Ingaruka: valve izangirika niba ari yoroheje, kandi impanuka yumutekano izaterwa niba iremereye
Ibipimo: intoki, intoki cyangwa ikiganza cyayo, yateguwe ukurikije abakozi basanzwe, urebye imbaraga zo gufunga hejuru nimbaraga zikenewe zo gufunga. Kubwibyo, ntabwo byemewe kugenda hamwe na leveri ndende cyangwa umugozi muremure. Abantu bamwe bamenyereye gukoresha umugozi, bagomba kwitondera cyane, ntibakoreshe imbaraga nyinshi, bitabaye ibyo biroroshye kwangiza hejuru yikimenyetso, cyangwa kumena intoki nintoki. Fungura kandi ufunge valve, imbaraga zigomba kuba zihamye, ntabwo ari ingaruka. Ibice bimwe byumuvuduko mwinshi hamwe no gufungura no gufunga byasuzumye imbaraga zingaruka kandi valve rusange ntishobora gutegereza. Kuri valve yamashanyarazi, mbere yo gufungura, igomba gushyukwa hakiri kare hanyuma ikavanwaho amazi. Iyo ufunguye, bizatinda bishoboka kugirango wirinde inyundo y'amazi. Iyo valve ifunguye neza, subiza uruziga rw'intoki inyuma gato, kugirango insinga zifatanye kugirango wirinde kwangirika no kwangirika. Kugirango ufungure ibiti, wibuke umwanya wikibaho mugihe ufunguye neza kandi ufunze byuzuye kugirango wirinde gukubita hejuru yapfuye iyo ifunguye neza. Nibyiza kugenzura niba ari ibisanzwe mugihe bifunze byuzuye. Niba ibiro bya valve biguye, cyangwa sundry nini yashyizwe hagati yikimenyetso cya kashe ya valve, umwanya wikibaho uzahinduka mugihe valve ifunze byuzuye. Iyo umuyoboro ukoreshejwe bwa mbere, haba hari umwanda mwinshi imbere, bityo valve irashobora gukingurwa gato. Umuvuduko wihuse wikigereranyo urashobora gukoreshwa mukwoza, hanyuma urashobora gufungwa gato (ntishobora gufungwa vuba cyangwa urugomo kugirango wirinde umwanda usigaye kwangiza hejuru yikimenyetso). Irashobora gufungura. Subiramo inshuro nyinshi, sukura umwanda, hanyuma ushyire mubikorwa bisanzwe. Iyo valve isanzwe ifunguye, hashobora kuba umwanda hejuru yikimenyetso. Iyo ifunze, uburyo bwavuzwe haruguru buzakoreshwa mu koza neza, hanyuma bufungwe kumugaragaro. Niba intoki n'intoki byangiritse cyangwa byatakaye, bigomba guhita bihuzwa, kandi ntibishobora gusimbuzwa umugozi woroshye, kugirango wirinde kwangiza impande enye z'uruti rwa valve no kunanirwa gukingura no gufunga, bikaviramo impanuka mubikorwa . Kubitangazamakuru bimwe, iyo valve ifunze hanyuma ikonje kugirango igabanye valve, uyikoresha agomba kongera kuyifunga mugihe gikwiye kugirango ubuso bwa kashe butagira kashe nziza. Bitabaye ibyo, itangazamakuru ritembera neza muburyo bwihuse kandi ryangiza byoroshye kashe. Mugihe cyo gukora, iyo bigaragaye ko igikorwa gikora cyane, impamvu zizasesengurwa. Niba gupakira ari binini cyane, birashobora kurekurwa neza. Niba igiti cya valve kigoramye, abakozi bamenyeshwa kugisana. Kuri valve zimwe, iyo zifunze, ibice byo gufunga birashyuha kandi bikagurwa, bigatuma gufungura bigoye; niba zigomba gukingurwa muriki gihe, zirashobora guhanagura umugozi wa bonnet igice cyumuzingi kugirango ukureho imihangayiko yikibaho, hanyuma wimure uruziga rwamaboko.

Kwishyiriraho nabi kwimyanya mubushyuhe bwo hejuru
Ingaruka: impanuka yamenetse
Ibipimo: kubushyuhe bwo hejuru hejuru ya 200 ℃, byashyizwe mubushyuhe busanzwe. Nyuma yo gukoresha bisanzwe, ubushyuhe burazamuka, ibimera byiyongera hamwe nubushyuhe, kandi icyuho kiriyongera. Kubwibyo, bagomba kongera gukomera, aribyo bita "gushyushya ubushyuhe". Umukoresha agomba kwitondera iki gikorwa, cyangwa kumeneka bizaba byoroshye.

Kudatwara igihe mugihe cyubukonje
Ingero: mugihe ikirere gikonje, valve yamazi ifunga igihe kirekire, kandi amazi yegeranijwe inyuma ya valve azakurwaho. Umuyoboro wamazi uhagaze, kondensate nayo igomba gukurwaho. Hasi ya valve ni nkicyuma, gishobora gukingurwa kumazi.

Umuyoboro udasanzwe, gufungura cyane no gufunga imbaraga
Ibipimo: bimwe mubitari ibyuma bitari ibyuma birakomeye kandi byoroshye, kandi bimwe muribi bifite imbaraga nke. Mugihe cyo gukora, imbaraga zo gufungura no gufunga ntizishobora kuba nini cyane cyane imbaraga zikomeye. Witondere kandi kutagusha ibintu.

Gupakira igitutu cya valve nshya irakomeye
Ingamba: mugihe hakoreshejwe valve nshya, gupakira ntibishobora gukanda cyane, kandi urwego rwo kumeneka ntiruzafatwa nkurwego, kugirango wirinde inkoni ya valve gukanda cyane, kwihutisha kwambara, no gukora gufungura no gufunga biragoye. Ubwiza bwo kwishyiriraho valve bugira ingaruka ku buryo butaziguye ku ikoreshwa, bityo rero birakenewe ko twita ku cyerekezo n'umwanya wa valve, kubaka valve, ibikoresho byo kurinda valve, bypass n'ibikoresho, gusimbuza paki.

Nta mwanya wo gukorera mumwanya wo kwishyiriraho
Ingero: umwanya wo kwishyiriraho valve ugomba kuba woroshye gukora; niyo kwishyiriraho bigoye byigihe gito, birakenewe kandi gutekereza kumurimo muremure wumukoresha. Nibyiza gukora uruziga rwamaboko ya valve rujya mu gituza (muri rusange 1,2m uvuye hasi), kugirango gufungura no gufunga valve birusheho kuba byiza. Uruziga rwamaboko ya valve rugwa hejuru, kandi ntirunye kugirango wirinde gukora nabi. Umuyoboro wimashini yegamiye urukuta nibikoresho nabyo bigomba gusiga umwanya uyobora. Ntabwo ari umutekano gukorera mu kirere, cyane cyane muri aside na alkali, itangazamakuru ryangiza, nibindi.

Imyanya ikozwe ningaruka ibikoresho byoroshye
Ingamba: kwishyiriraho no kubaka bigomba kwitonda kugirango wirinde gukubita valve ikozwe mubikoresho byoroshye. Mbere yo kwishyiriraho, genzura valve, reba ibisobanuro na moderi, hanyuma umenye niba hari ibyangiritse, cyane cyane kuruti rwa valve. Kuzenguruka kandi inshuro nke kugirango urebe niba ihindagurika, kuko mugihe cyo gutwara abantu, birashoboka cyane ko yakubita uruti. Kuraho kandi imyanda muri valve. Iyo uteruye valve, umugozi ntushobora guhambirwa ku ruziga rwamaboko cyangwa uruti, kugirango wirinde kwangirika kwibi bice, kandi bizahambirwa kuri flange. Umuyoboro uhujwe na valve ugomba gusukurwa. Umwuka uhunitse urashobora gukoreshwa muguhanagura ibyuma bya okiside ya fer, umucanga wibyondo, gusudira hamwe nizindi sundries. Iyi sundries ntabwo yoroshye gusa gushushanya hejuru yikimenyetso cya valve, ariko kandi irashobora guhagarika valve ntoya hanyuma ikagira agaciro. Iyo ushyizeho icyuma cya screw, gupakira kashe (ikivuguto n'amavuta ya sisitemu cyangwa umukandara wibikoresho bya polytetrafluoroethylene) bigomba gupfunyika kumutwe wumuyoboro, kandi ntibigomba gushyirwa mumurongo, kugirango wirinde ko valve yegeranya kandi ikagira ingaruka kumuzinduko wo hagati. . Mugihe ushyira flange ya flange, witondere gukomera kuri bolts muburyo bumwe kandi buringaniye. Umuyoboro wa valve hamwe nu muyoboro wa pipe bigomba kuba bifitanye isano no guhanagura neza, kugirango wirinde umuvuduko ukabije cyangwa ndetse no guturika kwa valve. Kubikoresho byacitse hamwe nimbaraga nkeya, hagomba kwitabwaho byumwihariko. Kugirango valve isudwe hamwe nu muyoboro, gusudira ahantu bigomba kubanza gukorwa, hanyuma igice gifunze kizakingurwa byuzuye, hanyuma valve izasudwa.
