Umphumela Wokushisa Nokucindezela Ekusebenzeni Kwevalvu Yebhathane
Amakhasimende amaningi asithumelela imibuzo, futhi sizophendula sibacele ukuthi banikeze uhlobo oluphakathi, izinga lokushisa eliphakathi kanye nengcindezi, ngoba lokhu akuthinti nje kuphela intengo yevalvu yevemvane, kodwa futhi kuyisici esibalulekile esithinta ukusebenza kwevalvu yevemvane. Umthelela wabo kuvalvu yevemvane uyinkimbinkimbi futhi uphelele.
1. Umphumela Wokushisa Ekusebenzeni Kwe-Butterfly Valve:
1.1. Izakhiwo Zezinto
Ezindaweni ezinokushisa okuphezulu, izinto ezifana nomzimba we-butterfly valve kanye nesiqu se-valve kudingeka zibe nokumelana okuhle nokushisa, ngaphandle kwalokho amandla nokuqina kuzothinteka. Ezindaweni ezinokushisa okuphansi, izinto zomzimba we-valve zizoba buthakathaka. Ngakho-ke, izinto ze-alloy ezingamelani nokushisa kumele zikhethwe ezindaweni ezinokushisa okuphezulu, futhi izinto ezinokuqina okuhle okungamelani nokubanda kumele zikhethwe ezindaweni ezinokushisa okuphansi.
Iyini izinga lokushisa lomzimba we-butterfly valve?
I-valve yebhabhathane yensimbi ethambile: -10℃ kuya ku-200℃
Ivalvu yebhabhathane le-WCB: -29℃ kuya ku-425℃.
I-valve yebhabhathane le-SS: -196℃ kuya ku-800℃.
Ivalvu yebhabhathane le-LCB: -46℃ kuya ku-340℃.
1.2. Ukusebenza Kokuvala
Ukushisa okuphezulu kuzokwenza isihlalo se-valve esithambile, indandatho yokuvala, njll. ukuthi sithambe, sande futhi siguquguquke, kuncishiswe umphumela wokuvala; kuyilapho izinga lokushisa eliphansi lingase liqinise izinto zokuvala, okuholela ekunciphiseni ukusebenza kokuvala. Ngakho-ke, ukuze kuqinisekiswe ukusebenza kokuvala ezindaweni zokushisa eziphakeme noma eziphansi, kubalulekile ukukhetha izinto zokuvala ezifanele izindawo zokushisa eziphakeme.
Okulandelayo izinga lokushisa lokusebenza kwesihlalo se-valve esithambile.
• I-EPDM -46℃ – 135℃ Elwa nokuguga
• I-NBR -23℃-93℃ Ayimelani Nowoyela
• I-PTFE -20℃-180℃ I-Anti-grosion kanye ne-chemical media
• I-VITON -23℃ – 200℃ Ilwa nokugqwala, ukumelana nokushisa okuphezulu
• I-Silica -55℃ -180℃ Ukumelana nokushisa okuphezulu
• NR -20℃ – 85℃ Ukunwebeka okuphezulu
• CR -29℃ – 99℃ Ayigugi, ayikhuli
1.3. Amandla esakhiwo
Ngikholwa ukuthi wonke umuntu uke wezwa ngomqondo obizwa ngokuthi "ukwanda nokuncipha kokushisa". Izinguquko zokushisa zizobangela ukuguquguquka kokucindezeleka kokushisa noma imifantu emajoyintini e-butterfly valve, ama-bolts nezinye izingxenye. Ngakho-ke, lapho uklama futhi ufaka ama-butterfly valve, kubalulekile ukucabangela umthelela wokushintsha kokushisa esakhiweni se-butterfly valve, bese uthatha izinyathelo ezifanele zokunciphisa umthelela wokwanda nokuncipha kokushisa.
1.4. Izinguquko ezicini zokugeleza
Izinguquko zokushisa zingathinta ubuningi kanye nokuthamba kwe-fluid medium, ngaleyo ndlela zithinte izici zokugeleza kwe-butterfly valve. Ekusetshenzisweni okungokoqobo, umthelela wokushintsha kwezinga lokushisa ezicini zokugeleza udinga ukucatshangelwa ukuqinisekisa ukuthi i-butterfly valve ingahlangabezana nezidingo zokulawula ukugeleza ngaphansi kwezimo ezahlukene zokushisa.
2. Umphumela Wokucindezela Ekusebenzeni Kwevalvu Yebhathane
2.1. Ukusebenza kokuvala
Uma ingcindezi ye-fluid medium ikhuphuka, i-butterfly valve idinga ukumelana nomehluko omkhulu wengcindezi. Ezindaweni ezinomfutho ophezulu, ama-butterfly valve kudingeka abe nokusebenza okwanele kokuvala ukuqinisekisa ukuthi ukuvuza akwenzeki lapho i-valve ivaliwe. Ngakho-ke, indawo yokuvala ama-butterfly valve ivame ukwenziwa nge-carbide nensimbi engagqwali ukuqinisekisa amandla nokumelana nokuguguleka kwendawo yokuvala.
2.2. Amandla esakhiwo
Ivalvu yebhabhathane Endaweni enomfutho ophezulu, ivalvu yebhabhathane idinga ukumelana nomfutho omkhulu, ngakho-ke izinto kanye nesakhiwo sevalvu yebhabhathane kumele kube namandla anele nokuqina. Isakhiwo sevalvu yebhabhathane ngokuvamile sihlanganisa umzimba wevalvu, ipuleti yevalvu, isiqu sevalvu, isihlalo sevalvu nezinye izingxenye. Amandla anganele anoma iyiphi yalezi zingxenye angabangela ukuthi ivalvu yebhabhathane yehluleke ngaphansi komfutho ophezulu. Ngakho-ke, kubalulekile ukucabangela ithonya lomfutho lapho uklama isakhiwo sevalvu yebhabhathane bese usebenzisa izinto ezifanele kanye nezakhiwo.
2.3. Ukusebenza kwevalvu
Indawo enomfutho ophezulu ingathinta i-torque yevalvu yebhabhathane, futhi ivalvu yebhabhathane ingadinga amandla amakhulu okusebenza ukuze ivuleke noma ivale. Ngakho-ke, uma ivalvu yebhabhathane ingaphansi komfutho ophezulu, kungcono ukukhetha ama-actuator kagesi, omoya kanye nezinye.
2.4. Ingozi yokuvuza
Ezindaweni ezinomfutho ophezulu, ingozi yokuvuza iyanda. Ngisho nokuvuza okuncane kungaholela ekuchithekeni kwamandla kanye nezingozi zokuphepha. Ngakho-ke, kubalulekile ukuqinisekisa ukuthi i-butterfly valve isebenza kahle ekuvaleni ezindaweni ezinomfutho ophezulu ukuze kuncishiswe ingozi yokuvuza.
2.5. Ukumelana nokugeleza okuphakathi
Ukumelana nokugeleza kwamanzi kuyinkomba ebalulekile yokusebenza kwevalvu. Kuyini ukumelana nokugeleza kwamanzi? Kubhekisela ekumelaneni okuhlangatshezwana nakho uketshezi oludlula evalvuni. Ngaphansi kokucindezela okuphezulu, ingcindezi ye-medium epuletini levalvu iyanda, okudinga ukuthi ivalvu yevemvane ibe namandla aphezulu okugeleza kwamanzi. Ngalesi sikhathi, ivalvu yevemvane idinga ukuthuthukisa ukusebenza kokugeleza kwamanzi futhi inciphise ukumelana nokugeleza kwamanzi.
Ngokuvamile, umthelela wokushisa kanye nengcindezi ekusebenzeni kwevalvu yebhabhathane kunezici eziningi, okuhlanganisa ukusebenza kokuvala, amandla esakhiwo, ukusebenza kwevalvu yebhabhathane, njll. Ukuze kuqinisekiswe ukuthi ivalvu yebhabhathane ingasebenza ngokujwayelekile ngaphansi kwezimo zokusebenza ezahlukene, kubalulekile ukukhetha izinto ezifanele, ukwakheka kanye nokuvala kwesakhiwo, futhi kuthathwe izinyathelo ezifanele zokubhekana nezinguquko ekushiseni nasekucindezelweni.
