Isikhokelo esibanzi sobunjineliIivalvu zeButterfly zePneumatic—igubungela iindlela zokuqhuba i-actuator,uyilo lwe-offset, ukubalwa kwe-torque, ukufakwa kwe-ISO 5211, kunye nemigangatho ye-API 609 yokwenza izinto ngokuzenzekelayo kwimizi-mveliso.
Isishwankathelo soLawulo: Yintoni iValve yeButterfly eSebenzayo ngePneumatic?
1. Umgaqo Wokusebenza kunye ne-Pneumatic Actuator Mechanics
I-othomathikhiivalvu yebhabhathane enomoyaiguqula uxinzelelo lwe-pneumatic (ngesiqhelo i-4.0–8.0 barumoya wesityalo) ungene kujikelezo lwe-mechanical shaft. Umoya ocinezelweyo usebenza ngokuchasene neepiston zangaphakathi okanye ii-diaphragmsngaphakathi kwendlu ye-actuator, eqhuba ishafti ejikelezayo engama-90° eqhagamshelwe kwidiski yevalvu nge-an
I-ISO 5211ujongano lweflange ephezulu.
Iintlobo zeeNkqubo zeButterfly Valve Actuator Drive
Ukukhetha okuchanekileyoi-actuator yevalvu yebhabhathanekuxhomekeke kwi-torque output curve, i-cycle frequency, kunye nobukhulu be-valve bore:
- Ii-Actuators zeRack kunye nePinion:Iipiston ezimbini ezinee-gear racks ezidityanisiweyo zibonelela ngomgca othe tyabai-torque kuyo yonke i-stroke ye-90°. I-compact footprint kunye ne-rapid cycling zibenza babe lishishiniumgangatho weevalvu ezizenzekelayo ezisuka kumbane ukuya kumbindi (DN40 ukuya ku-DN300).
- Ii-Actuators zeScotch Yoke:Indibano ye-joke pin-and-block ivelisa i-torque engeyiyo emgceniiprofayili enemveliso ephezulu kwiziphelo ze-stroke (ukuphuma kunye nokuhlala). Le nzuzo yoomatshini yenzazilungele ukusetyenziswa ngobukhulu obukhulu, ukusebenza okuphezulu, okanye izihlalo zentsimbiiivalvu zebhabhathane eziphindwe kathathu
(DN350 ukuya kwiDN1200+).
Iindlela zesenzo se-Pneumatic: Ukusebenza kabini vs. Ukubuya kwentwasahlobo
| Uqwalaselo lwe-Actuator | Indlela Yokusebenza | Imeko yesenzo esikhuselekileyo |
|---|---|---|
| Ukusebenza kabini (DA) | Ifuna umoya ocinezelweyo kwiPort A ukuze ivuleke kwaye iPort B ivale. | Indawo yokusilela:Ibamba indawo yangoku xa umoya ulahlekile. |
| Ukubuya kweNtwasahlobo (i-SR / i-Slender Acting) | Uxinzelelo lomoya luqhuba kwicala elinye ngelixa lucinezela izipringi zangaphakathi. Izipringi ziqhuba isipitshi esichaseneyo. | Ikhuselekile kwiMechanical:Itshintshela ngokuzenzekelayo kwiUkusilela-Ukuvala (FC) or I-Fail-Open (FO)xa umoya ungasebenzi. |
Ingqiqo yoBunjineli obuPhambili
Kwizicelo ezibalulekileyo kukhuseleko (umz., iinkqubo zokuvala ngexesha likaxakeka), soloko ucacisaii-actuators zokubuya kwentwasahlobokwindawo efanelekileyo yokukhusela ukusilela. Ii-actuators ezisebenza kabini zikhethwa xa kulungiswa ulawulo aphoukugcina indawo ngexesha lokuphelelwa ngumbane kuyamkeleka.
2. Ulwakhiwo lomzimba weValve kunye neendidi zoyilo lwe-Offset
Ukususwa komatshini kwe-disc shaft kulawula i-torque yokusebenza, ukungqubana kwesihlalo, kunye nokukwazi ukufudumalayeivalvu yebhabhathane yohlobo lwe-actuator:
1. Iivalvu zebhabhathane ezixineneyo (ezihlala ziqinile)
Isiqu sibekwe embindini wediski kunye nembobo yesitulo. Isebenzisa ii-liner ezithambileyo ze-elastomeric (EPDM, NBR,iViton, okanye iPTFE) ukufezekisaUkuvalwa kokuvuza okungavuziyo kwe-ANSI/FCI 70-2 Class VI. Eyona ifanelekileyokwiinkonzo zamanzi, umoya, i-HVAC, kunye neekhemikhali eziphantsi koxinzelelo oluphantsi ukuya kuthi ga kwi-16 bar kunye ne-150°C.
2. Iivalvu zeButterfly ze-Offset ezimbini (ezisebenza kakuhle)
Umahluko phakathi kweshafti kunye nesiseko sesihlalo kunye nebhore yepayipi. Oku kungavakali kabini kubangela idiski"ukuphakamisa" isihlalo ngexesha lokujikeleza, ukunciphisa ukungqubana, ukunciphisa i-torque yokuhlala, kunye nokwandisa isihlaloubomi benkonzo. Ifumaneka ngezihlalo ezithambileyo ze-PTFE/RPTFE okanye iiringi zesitywino zesinyithi eziguquguqukayo zoxinzelelo oluphakathi
imigca yomphunga kunye nenkqubo.
3. Iivalvu zebhabhathane ezine-Triple Offset (TOBV) Metal-Seat Butterfly Valves
Inendawo yesithathu ye-offset edityaniswe kwi-geometry yekhoni yesihlalo. Le ayikhuhli, ayisebenzi kakuhle.uyilo lufezekisa ukujikeleza okungenazingxabano kunye nezihlalo eziqinileyo ukusuka kwisinyithi ukuya kwisinyithi (iStellite / Laminated StainlessYenziwe ngentsimbi). Yenzelwe inkonzo enzima, amaqondo obushushu aphezulu ukuya kuthi ga kwi-550°C+, ulwelo oluyi-cryogenic, kunye nokhuseleko emlilweni.imisebenzi.
Iinketho Zokuphelisa Uqhagamshelo
- Uhlobo lweWafer:Umzimba oxineneyo ubanjwe phakathi kweeflange zepayipi ngeebholithi ezidlulayo. Ubunzima obuphantsi kunye nophawu olusezantsi.
- Uhlobo lweLug:Iilugs ezinemisonto emzimbeni ezihambelana neepateni zebholithi yeflange. Ivumela inkonzo engapheliyo kunye nokugcinwa komgca ongezantsi.
- Uhlobo oluphindwe kabini:Iiflange ezidityanisiweyo kuzo zombini iziphelo; kuyimfuneko kwiidayamitha ezinkulu (DN300+) kunye nokufakelwa koxinzelelo lwemibhobho egqunyiweyo okanye enzima.
3. Izixhobo zeLoop yoLawulo oluZenzekelayo

5. Imibuzo Ebuzwa Rhoqo (Imibuzo Ebuzwa Rhoqo Ngobunjineli)
Q1: Ngaba ivalvu yebhabhathane ye-pneumatic actuator ingasetyenziselwa ukulawula ukuhamba kwamanzi ngokuchanekileyo?
Ewe. Ngokuxhobisa ivalvu yebhabhathane ephindwe kabini okanye ejikelezileyo ene-digital electro-pneumatic positioner(Isignali ye-4–20mA), indibano isebenza njengevalvu yokulawula esebenza kakuhle yokulawula ukuhamba kwamanzi aphezulu kunye noxinzelelo oluphantsiimibhobho yokuwisa.
Umbuzo 2: Yeyiphi inzuzo ephambili yevalvu yebhabhathane yohlobo lwe-actuator ngaphezu kwevalvu yebhola?
Iivalvu zebhabhathane ezisebenzisa umoya zikhaphukhaphu kakhulu, zincinci xa zijongwa ubuso ngobuso, kwaye zinkulu kakhuluixabiso liphantsi kakhulu kwiisayizi ezinkulu zemigca (DN200 / 8-intshi nangaphezulu) xa kuthelekiswa neevalvu zebhola ezinobukhulu obulinganayo.
UMBUZO 3: Kutheni umgangatho wokufakelwa kwe-ISO 5211 ubalulekile kwi-actuator ye-butterfly valve?
I-ISO 5211 ichaza iipateni zebholithi ezifanayo, ubukhulu beshaft yokuqhuba, kunye nobukhulu beflange. Oku kuqinisekisa ukuba imigangatho iyafana.ukutshintshiselana, okuvumela ii-actuators zomoya ezivela kubavelisi abahlukeneyo ukuba zifake ngqo kwiziqu zevalvungaphandle kwezibiyeli ezenziwe ngokwezifiso.
Umbuzo 4: Yintoni umahluko phakathi kweevalvu zebhabhathane ezihlala phantsi ezithambileyo nezihlala phantsi kwesinyithi?
Iivalvu ezithambileyo zisebenzisa izihlalo ze-elastomeric okanye ze-PTFE ukuze zivalwe zingaphumi xa kushushu kakhulu.(ngesiqhelo i-≤150°C). Iivalvu ezihlala ngentsimbi (i-triple offset) zisebenzisa i-metal-to-metal sealing kwaye ziyakwazi ukumelanaamaqondo obushushu afikelela kwi-550°C+, nto leyo eyenza ukuba zilungele umphunga, ioyile yobushushu, kunye neenkonzo ze-cryogenic.
