Isiphumo soBushushu kunye noXinzelelo ekusebenzeni kweValve yeButterfly
Abathengi abaninzi basithumelela imibuzo, kwaye siya kubaphendula sibacela ukuba banike uhlobo oluphakathi, ubushushu obuphakathi kunye noxinzelelo, kuba oku akuchaphazeli nje kuphela ixabiso levalvu yebhabhathane, kodwa kukwayinto ephambili echaphazela ukusebenza kwevalvu yebhabhathane. Impembelelo yabo kwivalvu yebhabhathane inzima kwaye ibanzi.
1. Impembelelo yoBushushu kwiNkqubo yeValve yeButterfly:
1.1. Iimpawu zezinto
Kwiindawo ezinobushushu obuphezulu, izinto ezifana nomzimba wevalvu yebhabhathane kunye nesiqu sevalvu kufuneka zibe nokumelana okuhle nobushushu, kungenjalo amandla kunye nobunzima buya kuchaphazeleka. Kwindawo enobushushu obuphantsi, izinto zomzimba wevalvu ziya kuba buthathaka. Ke ngoko, izinto ze-alloy ezimelana nobushushu kufuneka zikhethwe kwiindawo ezinobushushu obuphezulu, kwaye izinto ezinobunzima obuhle obumelana nokubanda mazikhethwe kwiindawo ezinobushushu obuphantsi.
Ingakanani iqondo lobushushu lomzimba wevalvu yebhabhathane?
Ivalvu yebhabhathane yentsimbi ethambileyo: -10℃ ukuya kwi-200℃
Ivalvu yebhabhathane yeWCB: -29℃ ukuya kwi-425℃.
Ivalvu yebhabhathane ye-SS: -196℃ ukuya kwi-800℃.
Ivalvu yebhabhathane ye-LCB: -46℃ ukuya kwi-340℃.
1.2. Ukusebenza kokutywina
Ubushushu obuphezulu buya kubangela ukuba isihlalo sevalvu ethambileyo, iringi yokutywina, njl.njl. zithambise, zande kwaye ziguquguquke, nto leyo enciphisa isiphumo sokutywina; ngelixa ubushushu obuphantsi bunokuqinisa izinto zokutywina, nto leyo ebangela ukwehla kokusebenza kokutywina. Ke ngoko, ukuqinisekisa ukusebenza kokutywina kwiindawo ezinobushushu obuphezulu okanye obuphantsi, kuyimfuneko ukukhetha izinto zokutywina ezifanelekileyo kwiindawo ezinobushushu obuphezulu.
Okulandelayo luluhlu lobushushu bokusebenza kwesihlalo sevalvu ethambileyo.
• I-EPDM -46℃ – 135℃ Ithintela ukwaluphala
• I-NBR -23℃-93℃ Ayikwazi ukumelana neoyile
• I-PTFE -20℃ -180℃ I-Anti-corrosion kunye ne-chemical media
• I-VITON -23℃ – 200℃ Iyachasana nokugqwala, ukumelana nobushushu obuphezulu
• I-Silica -55℃ -180℃ Ukumelana nobushushu obuphezulu
• NR -20℃ – 85℃ Ukuthamba okuphezulu
• CR -29℃ – 99℃ Ayigugi, ayikhuli
1.3. Amandla olwakhiwo
Ndikholelwa ukuba wonke umntu ukhe weva ngengcamango ebizwa ngokuba "ukwandiswa kobushushu kunye nokucutheka". Utshintsho lobushushu luya kubangela ukuguquguquka koxinzelelo lobushushu okanye ukuqhekeka kwamalungu evalvu yebhabhathane, iibholiti kunye nezinye iindawo. Ke ngoko, xa uyila kwaye ufaka iivalvu zebhabhathane, kuyimfuneko ukuqwalasela impembelelo yotshintsho lobushushu kwisakhiwo sevalvu yebhabhathane, kwaye uthathe amanyathelo afanelekileyo ukunciphisa impembelelo yokwandiswa kunye nokucutheka kobushushu.
1.4. Utshintsho kwiimpawu zokuhamba kwamanzi
Utshintsho lobushushu lunokuchaphazela uxinano kunye nokuxinana kwe-fluid medium, ngaloo ndlela luchaphazela iimpawu zokuhamba kwe-butterfly valve. Kwiindlela ezisebenzayo, impembelelo yotshintsho lobushushu kwiimpawu zokuhamba kufuneka iqwalaselwe ukuqinisekisa ukuba i-butterfly valve inokuhlangabezana neemfuno zokulawula ukuhamba phantsi kweemeko ezahlukeneyo zobushushu.
2. Isiphumo soxinzelelo ekusebenzeni kwevalvu yebhabhathane
2.1. Ukusebenza kokutywina
Xa uxinzelelo lwe-fluid medium lusanda, ivalvu yebhabhathane kufuneka imelane nomahluko omkhulu woxinzelelo. Kwiindawo ezinoxinzelelo oluphezulu, iivalvu zebhabhathane kufuneka zibe nokusebenza okwaneleyo kokuvala ukuqinisekisa ukuba ukuvuza akwenzeki xa ivalvu ivaliwe. Ke ngoko, umphezulu wokuvala iivalvu zebhabhathane uhlala wenziwe nge-carbide kunye nentsimbi engagqwaliyo ukuqinisekisa amandla kunye nokumelana nokuguguleka komphezulu wokuvala.
2.2. Amandla olwakhiwo
Ivalvu yebhabhathane Kwimeko enoxinzelelo oluphezulu, ivalvu yebhabhathane kufuneka imelane noxinzelelo olukhulu, ngoko ke izinto kunye nolwakhiwo lwevalvu yebhabhathane kufuneka zibe namandla aneleyo kunye nokuqina. Ulwakhiwo lwevalvu yebhabhathane ludla ngokuquka umzimba wevalvu, ipleyiti yevalvu, isiqu sevalvu, isihlalo sevalvu kunye nezinye izinto. Amandla angonelanga alo naliphi na kwezi zinto anokubangela ukuba ivalvu yebhabhathane ingaphumeleli phantsi koxinzelelo oluphezulu. Ke ngoko, kuyimfuneko ukuqwalasela impembelelo yoxinzelelo xa uyila isakhiwo sevalvu yebhabhathane kwaye wamkele izixhobo ezifanelekileyo kunye neendlela zokwakha.
2.3. Ukusebenza kwevalvu
Indawo enoxinzelelo oluphezulu inokuchaphazela i-torque yevalvu yebhabhathane, kwaye ivalvu yebhabhathane inokufuna amandla amakhulu okusebenza ukuze ivuleke okanye ivalwe. Ke ngoko, ukuba ivalvu yebhabhathane iphantsi koxinzelelo oluphezulu, kungcono ukhethe ii-actuator zombane, ze-pneumatic kunye nezinye.
2.4. Umngcipheko wokuvuza
Kwiindawo ezinoxinzelelo oluphezulu, umngcipheko wokuvuza uyanda. Nokuba ukuvuza okuncinci kunokukhokelela ekuchithekeni kwamandla kunye neengozi zokhuseleko. Ke ngoko, kuyimfuneko ukuqinisekisa ukuba ivalvu yebhabhathane isebenza kakuhle ekuvaleni kwiindawo ezinoxinzelelo oluphezulu ukunciphisa umngcipheko wokuvuza.
2.5. Ukumelana nokuhamba kwamanzi okuphakathi
Ukumelana nokuhamba kwamanzi luphawu olubalulekileyo lokusebenza kwevalvu. Kuthetha ukuthini ukumelana nokuhamba kwamanzi? Kubhekisa ekuxhathiseni okuhlangatyezwa lulwelo oludlula kwivalvu. Phantsi koxinzelelo oluphezulu, uxinzelelo lwendlela ephakathi kwipleyiti yevalvu luyanda, nto leyo edinga ukuba ivalvu yebhabhathane ibe namandla aphezulu okuhamba kwamanzi. Ngeli xesha, ivalvu yebhabhathane kufuneka iphucule ukusebenza kokuhamba kwamanzi kwaye inciphise ukumelana nokuhamba kwamanzi.
Ngokubanzi, impembelelo yobushushu kunye noxinzelelo ekusebenzeni kwevalvu yebhabhathane inamacandelo amaninzi, kubandakanya ukusebenza kokutywina, amandla olwakhiwo, ukusebenza kwevalvu yebhabhathane, njl. Ukuze kuqinisekiswe ukuba ivalvu yebhabhathane isebenza ngokuqhelekileyo phantsi kweemeko ezahlukeneyo zokusebenza, kuyimfuneko ukukhetha izixhobo ezifanelekileyo, uyilo kunye nokutywina kolwakhiwo, kwaye kuthathwe amanyathelo afanelekileyo okujongana notshintsho kubushushu kunye noxinzelelo.
