Ubuyobozi bwuzuye bw'ubuhanga bwoValves z'ibinyugunyugu zo mu mwuka—ikubiyemo uburyo bwo gutwara actuator,Imiterere ya offset, kubara torque, gushyiraho ISO 5211, n'amahame ya API 609 yo gukoresha ikoranabuhanga mu nganda.
Incamake y'Ubuyobozi: Valve y'ikinyugunyugu ikoreshwa mu mwuka ni iki?
1. Ihame ry'imikorere n'ubuhanga mu by'amashanyarazi mu by'umwuka
Ikoranabuhanga rikora mu buryo bwikoravalve y'ikinyugunyugu gihumekaihindura umuvuduko w'umwuka (ubusanzwe 4.0–8.0 barumwuka utangwa n'ibimera) mu buryo bwa mekanike. Umwotsi ufunze ukora ku mapiston y'imbere cyangwa diaphragmmu cyumba cy'imashini ikoresha actuator, ikoresha umugozi uzenguruka wa 90° uhujwe na disiki ya valve unyuze kuri
ISO 5211urwego rwo hejuru rw'ikirango.
Ubwoko bwa sisitemu yo gutwara valve y'ikinyugunyugu
Guhitamo igikwiyeicyuma gikoresha amashanyarazi cya valve y'ikinyugunyugubiterwa n'umuvuduko w'ingufu zisohoka, ingano y'uruziga, n'ingano y'agasanduku k'amashanyarazi:
- Ibikoresho bya Rack na Pinion:Piston ebyiri zifite ibikoresho byabugenewe bitanga umurongo ugororotseimbaraga zikoreshwa mu gushyuha kwa dogere 90. Imiterere mito n'ingufu zikoreshwa mu gusiganwa ku maguru bibagira ingandaibisanzwe kuri valve zikoresha amashanyarazi kuva ku mucyo kugeza ku gipimo (DN40 kugeza DN300).
- Ibikoresho bya Scotch Yoke:Iteraniro ry'ingoyi n'ibumba ritanga umuvuduko utari umurongoimiterere ifite umusaruro mwinshi ku mpera z'imitsi (guhagarara no kwicara). Iyi nyungu ya mekanike itumani byiza cyane ku bikoresho bifite uburebure bunini, bikora neza cyane, cyangwa ibyumavalve eshatu z'ibinyugunyugu zikoreshwa mu gupima ibinyugunyugu
(DN350 kugeza DN1200+).
Uburyo bwo gukora ibikorwa bya pneumatic: Gukora kabiri ugereranije no kugaruka mu mpeshyi
| Imiterere ya Actuator | Uburyo bwo Gukora | Imiterere y'ibikorwa bidatekanye |
|---|---|---|
| Double Acting (DA) | Bisaba umwuka ufunze kuri Port A kugira ngo bifunguke kandi Port B ifunge. | Kunanirwa mu mwanya wabyo:Iguma aho ihagaze iyo umwuka ubuze. |
| Gusubira mu mpeshyi (SR / Umukinnyi w'imikino utari uwabo) | Umuvuduko w'umwuka uyobora icyerekezo kimwe mu gihe ukandagira amasoko y'imbere. Amasoko ayobora inzira inyuranye. | Ingeso mbi za tekiniki:Ihinduka mu buryo bwikora ijya kuriGutsindwa-Gufunga (FC) or Gupfa-Gufungura (FO)iyo umwuka upfuye. |
Inyigisho z'ingenzi z'Ubwubatsi
Ku bijyanye n'ibikorwa by'ingenzi mu mutekano (urugero, sisitemu zo gufunga byihutirwa), buri gihe garagazaibikoresho bitanga ingufu zo kugarura imvura mu mpeshyihamwe n'umwanya ukwiye wo kwirinda kwangirika. Imashini zikora inshuro ebyiri ni zo zikundwa mu guhindura uburyo bwo kugenzura ahoKugumana umwanya mu gihe cy'ibura ry'amashanyarazi biremewe.
2. Ubwoko bw'imiterere y'imiyoboro ya Valve n'imiterere ya Offset
Uburyo bwo gusimbuza disiki bukoresha ikoranabuhanga rituma habaho imbaraga zo gukora, ubwivumbure bw'intebe, n'ubushobozi bwo gushyuha.by'umuntuvalve y'ikinyugunyugu yo mu bwoko bwa actuator:
1. Valves z'ibinyugunyugu zifata ahantu hakomeye (zifite intebe ihamye)
Ifite igiti kiri hagati hagati ya disiki n'agace k'intebe. Ikoresha imigozi yoroshye ya elastomeric (EPDM, NBR,Viton, cyangwa PTFE) kugira ngo bigerwehoANSI/FCI 70-2 Class VI irafunga nta gusohoka kw'amazi. Ikwiriye cyaneku mazi, umwuka, HVAC, na serivisi z'imiti yoroheje ifite umuvuduko muke kugeza kuri 16 bar na 150°C.
2. Valve ebyiri z'ikinyugunyugu (zikora neza)
Umugozi uva hagati y'intebe n'aho hagati y'umuyoboro w'amazi. Uku guhindagurika kubiri ni byo bituma disiki"gukura" ku ntebe mu gihe cyo kuzenguruka, kugabanya gukururana, kugabanya imbaraga zo kwicaraho, no kongera umwanya wo kwicarahoIgihe cyo kuyikoresha. Iboneka hamwe n'intebe zoroshye za PTFE/RPTFE cyangwa impeta zoroshye zo gufunga ibyuma kugira ngo ikoreshwe mu buryo buringaniye.
imiyoboro y'umwuka n'iy'imikorere.
3. Valve z'ibinyugunyugu zikozwe mu byuma (TOBV) zifite icyuma
Ifite inguni ya gatatu ya offset ikubiye mu ishusho y'agace k'intebe. Iyi shusho ntikora cyane, kandi ikora neza.Igishushanyo mbonera kigera ku kuzunguruka kudahindagurika no kwicara hagati y'icyuma n'icyuma (Stellite / Laminated StainlessIcyuma). Cyakozwe mu rwego rwo gukora cyane, ubushyuhe bwinshi kugeza kuri 550°C+, amazi ashyushye kandi akoreshwa mu buryo butangiza umuriro.ibikorwa.
Amahitamo yo Guhagarika Ihuza
- Ubwoko bwa Wafer:Umubiri muto ufatanye hagati y'imiyoboro ifunganye hakoreshejwe bolts. Uburemere n'aho umuntu ahagaze ni bike cyane.
- Ubwoko bw'ikirenge:Udupira tw’imigozi ku mubiri duhuye n’imiterere ya flange bolt. Bituma serivisi idakora neza kandi bigakorwa neza.
- Ubwoko bw'ibice bibiri:Udupira tw’amashanyarazi dufatanye ku mpera zombi; ni ngombwa ku miyoboro minini (DN300+) n’imiyoboro itwikiriwe cyangwa iremereye.

5. Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa mu Buhanga)
Q1: Ese valve y'ikinyugunyugu ikoresha umwuka ishobora gukoreshwa mu kugenzura neza imikorere y'amazi?
Yego. Mu gushyira valve y'ibinyugunyugu ifite ikoranabuhanga rikoresha amashanyarazi n'umwuka (digital electro-pneumatic positioner) ifite icyuma gikingira umwuka (double offset or concentric butterfly valve).(ikimenyetso cya 4–20mA), iyi teraniro ikora nk'ingufu igenzura neza ikoreshwa mu gutuma umuvuduko urushaho kwiyongera kandi ugabanukaimiyoboro y'amazi imanuka.
Q2: Ni iyihe nyungu nyamukuru ya valve y'ikinyugunyugu yo mu bwoko bwa actuator kurusha valve y'umupira?
Udupira tw'ibinyugunyugu dukoresha umwuka tuba tworoheje cyane, duto cyane mu ngano z'imbonankubone, kandi dukomeye cyaneihendutse cyane mu ngano nini z'umurongo (DN200 / santimetero 8 no hejuru) ugereranije na valve z'umupira zingana.
Q3: Kuki igipimo ngenderwaho cya ISO 5211 ari ingenzi kuri actuator ya valve y'ikinyugunyugu?
ISO 5211 isobanura imiterere y'amaboliti amwe, ingano z'umugozi wo gutwara, n'ingano z'urukiramende. Ibi byemeza ko bihuye n'imiterere y'amaboliti.guhindagurika, bigatuma ibikoresho bikoresha umwuka biva mu nganda zitandukanye bishyirwa ku giti cya valventa dukingirizo twihariye.
Q4: Ni irihe tandukaniro riri hagati y'udupira tw'ibinyugunyugu twicaye mu buryo bworoshye n'utw'icyuma?
Valves zoroshye zikoresha intebe za elastomeric cyangwa PTFE kugira ngo zihagarike nta gusohoka kw'amazi ku bushyuhe buri hasi.(ubusanzwe ≤150°C). Vali zicaye mu cyuma (zifite ibice bitatu) zikoresha uburyo bwo kuzifunga kuva ku cyuma kugera ku cyuma kandi zishobora kwihanganiraubushyuhe bugera kuri 550°C+, bigatuma biba byiza gukoreshwa mu mwuka w'umwuka, amavuta ashyushye, na serivisi zo gushyushya.
