Isiphumo sobushushu kunye noxinzelelo kuMsebenzi weValve yebhabhathane
Abathengi abaninzi basithumelela imibuzo, kwaye siya kuphendula sibacela ukuba banikeze uhlobo oluphakathi, ubushushu obuphakathi kunye noxinzelelo, kuba oku akuchaphazeli nje ixabiso le-valve butterfly, kodwa yinto ephambili echaphazela ukusebenza kwe-valve butterfly.Impembelelo yabo kwivalve yebhabhathane iyinkimbinkimbi kwaye ibanzi.
1. Impembelelo yoBubushushu kwiNtsebenzo yeValve yebhabhathane:
1.1.Iipropati zeMathiriyeli
Kwiindawo ezinobushushu obuphezulu, izinto ezifana ne-butterfly valve body kunye ne-valve stem kufuneka zibe nokumelana nokushisa okulungileyo, ngaphandle koko amandla kunye nobunzima buya kuchaphazeleka.Kwimeko yobushushu obuphantsi, imathiriyeli yomzimba wevalvu iya kuba brittle.Ke ngoko, izixhobo ze-alloy ezikwazi ukumelana nobushushu kufuneka zikhethwe kwindawo ezinobushushu obuphezulu, kwaye izinto ezinobulukhuni obunganyangekiyo ukubanda kufuneka zikhethwe kwindawo ezinobushushu obuphantsi.
Lithini izinga lobushushu kumzimba wevalve yebhabhathane?
Ivalve yebhabhathane yentsimbi: -10℃ ukuya kuma-200℃
Ivalve yebhabhathane yeWCB: -29℃ ukuya ku-425℃.
Ivalve yebhabhathane ye-SS: -196℃ ukuya ku-800℃.
Ivalve yebhabhathane LCB: -46℃ ukuya kwi-340℃.
1.2.Ukutywinwa kokuSebenza
Ubushushu obuphezulu buya kubangela ukuba isitulo sevalve ethambileyo, umsesane wokutywina, njl.ngelixa ubushushu obuphantsi bunokwenza lukhuni izinto zokutywina, okukhokelela ekunciphiseni kokutywinwa kokusebenza.Ngoko ke, ukwenzela ukuba kuqinisekiswe ukusebenza kokutywinwa kwiindawo eziphezulu okanye eziphantsi kweqondo lokushisa, kuyimfuneko ukukhetha izinto zokutywina ezifanelekileyo kwiindawo zokushisa eziphezulu.
Okulandelayo luluhlu lweqondo lokushisa lokusebenza kwesitulo sevalve ethambileyo.
• EPDM -46℃ – 135℃ Anti-aging
• I-NBR -23℃-93℃ I-Oil Resistant
• PTFE -20℃-180℃ Anti-corrosion kunye neekhemikhali media
• VITON -23℃ – 200℃ Anti-corrosion, ukumelana nobushushu obuphezulu
• I-Silica -55 ℃ -180 ℃ ukumelana nobushushu obuphezulu
• I-NR -20℃ - 85℃ Ukuqina okuphezulu
• CR -29℃ – 99℃ Ukunganxibi, ukulwa nokuguga
1.3.Amandla okwakhiwa
Ndiyakholelwa ukuba wonke umntu uvile ngengcamango ebizwa ngokuthi "ukwandiswa kwe-thermal kunye nokunciphisa".Utshintsho lobushushu luya kubangela ukuguqulwa koxinzelelo lwe-thermal okanye ukuqhekeka kumalungu evalve yebhabhathane, iibholiti kunye nezinye iindawo.Ngoko ke, xa uyila kwaye ufaka i-valve ye-butterfly, kuyimfuneko ukuqwalasela impembelelo yokutshintsha kweqondo lokushisa kwisakhiwo se-butterfly valve, kwaye uthathe amanyathelo ahambelanayo okunciphisa impembelelo yokwandiswa kwe-thermal kunye nokunciphisa.
1.4.Utshintsho kwiimpawu zokuhamba
Ukutshintsha kobushushu kunokuchaphazela ukuxinana kunye ne-viscosity ye-fluid medium, ngaloo ndlela kuchaphazela iimpawu zokuhamba kwevalve yebhabhathane.Kwizicelo ezisebenzayo, impembelelo yokutshintsha kweqondo lokushisa kwiimpawu zokuhamba kufuneka ziqwalaselwe ukuze kuqinisekiswe ukuba i-valve yebhabhathane inokuhlangabezana neemfuno zokulawula ukuhamba phantsi kweemeko ezahlukeneyo zobushushu.
2. Impembelelo yoxinzelelo kwiNtsebenzo yeValve yeButterfly
2.1.Ukusebenza kokutywina
Xa uxinzelelo oluphakathi kwamanzi lusanda, ivalve yebhabhathane kufuneka imelane noxinzelelo olukhulu.Kwiindawo ezinoxinzelelo oluphezulu, iivalve zebhabhathane kufuneka zibe nokusebenza ngokwaneleyo kokutywina ukuze kuqinisekiswe ukuba ukuvuza akwenzeki xa ivalve ivaliwe.Ngoko ke, indawo yokutywinwa kweevalve zebhabhathane ngokuqhelekileyo zenziwe nge-carbide kunye nensimbi engenasici ukuze kuqinisekiswe amandla kunye nokuxhatshazwa kokugqoka kwendawo yokutywina.
2.2.Amandla okwakhiwa
Ivalve yebhabhathane Kwimeko-bume yoxinzelelo oluphezulu, ivalve yebhabhathane kufuneka imelane noxinzelelo olukhulu, ngoko ke imathiriyeli kunye nokwakheka kwevalve yebhabhathane kufuneka ibe namandla okwaneleyo kunye nobungqongqo.Ulwakhiwo lwevalve yebhabhathane ngokuqhelekileyo lubandakanya umzimba wevalve, ipleyiti yevalvu, isiqu sevalvu, isihlalo sevalvu kunye namanye amacandelo.Ukungoneli kwalo naliphi na lala malungu kunokubangela ukuba ivalve yebhabhathane ingasebenzi phantsi koxinzelelo oluphezulu.Ngoko ke, kuyimfuneko ukuqwalasela impembelelo yoxinzelelo xa uyila isakhiwo se-valve butterfly kwaye wamkele izinto ezifanelekileyo kunye neefom zesakhiwo.
2.3.Ukusebenza kwevalvu
Indawo yoxinzelelo oluphezulu inokuchaphazela i-torque yevalve yebhabhathane, kwaye ivalve yebhabhathane inokufuna amandla amakhulu okusebenza ukuvula okanye ukuvala.Ngoko ke, ukuba i-valve ye-butterfly iphantsi koxinzelelo oluphezulu, kungcono ukhethe umbane, i-pneumatic kunye nezinye i-actuator.
2.4.Umngcipheko wokuvuza
Kwiindawo ezinoxinzelelo oluphezulu, umngcipheko wokuvuza uyanda.Nokuvuza okuncinci kunokukhokelela kwinkcitho yamandla kunye neengozi zokhuseleko.Ngoko ke, kuyimfuneko ukuqinisekisa ukuba i-valve yebhabhathane inomsebenzi wokutywina kakuhle kwiindawo ezinoxinzelelo oluphezulu ukunciphisa umngcipheko wokuvuza.
2.5.Ukumelana nokuhamba okuphakathi
Ukuchasana nokuhamba kuyisalathisi esibalulekileyo sokusebenza kwevalve.Yintoni ukuxhathisa ukuhamba?Ibhekisa kuxhathiso olufunyanwa lulwelo oludlula kwivalvu.Ngaphantsi koxinzelelo oluphezulu, uxinzelelo oluphakathi kwipleyiti yevalve luyanda, lufuna ukuba ivalve yebhabhathane ibe nomthamo ophezulu wokuhamba.Ngeli xesha, i-valve butterfly idinga ukuphucula ukusebenza kokuhamba kunye nokunciphisa ukuxhathisa ukuhamba.
Ngokuqhelekileyo, impembelelo yeqondo lokushisa kunye noxinzelelo kwi-valve ye-butterfly i-valve ine-multifaceted, kubandakanywa ukusebenza kokutywinwa, amandla okwakhiwa, i-valve ye-butterfly valve, njl. izinto ezifanelekileyo, uyilo lwesakhiwo kunye nokutywinwa, kunye nokuthatha amanyathelo ahambelanayo ukuhlangabezana nokutshintsha kweqondo lokushisa kunye noxinzelelo.
