5Indlela Yokubala Usayizi We-Actuator kanye Ne-Torque
Ukwenza ivalvu yebhola enezindlela ezintathu ngokuzenzakalela kudinga ukubalwa kwe-torque ngokucophelela ukuze kuvinjelwe ukumiswa kwe-actuator, ukucheba isiqu, noma ukuvalwa okunganele ngaphansi kwezimo zokusebenza ezimbi kakhulu. Ngenxa yokuthi ivalvu enezindlela ezintathu enezihlalo ezine igcina ukuxhumana okuqhubekayo ezivalweni ezine zezihlalo ezilayishiwe ngaphambilini, i-torque yayo ephukile (Tb) iphakeme kakhulu kunevalvu yebhola entantayo enezihlalo ezimbili ejwayelekile enobukhulu obufanayo—ngokuvamile iphakeme ngo-40-60%.
Ifomula Yokulinganisa I-Torque
Ukuze kutholakale i-torque ye-actuator edingekayo encane (Ta) ngaphansi kwezimo zokucindezela okukhulu komehluko (ΔP):
Kuphi:
- Tb= I-torque yokuqhekeka eyisisekelo enikezwa umenzi we-valve (ilinganiswa ngokucindezela okukhulu komehluko kanye nokushisa okuphezulu)
- SF= Isici Sokuphepha Kohlelo Lokusebenza (bheka ithebula elingezansi)
Izici Zokuphepha Ezinconyiwe Ngokwesimo Sesevisi
| Isimo Sesevisi | Isici Sokuphepha (SF) | Ukufaneleka Kobunjiniyela |
|---|---|---|
| Uketshezi oluhlanzekile lokugcoba (amanzi ahlanzekile, uwoyela we-hydraulic, ama-hydrocarbon alula) | 1.25 | I-margin engu-25% ibangela ukuguguleka okuncane kwezihlalo kanye nokuguquguquka kwe-viscosity |
| Imidiya engagcobi (umoya, igesi eyomile, amanzi angenawo amaminerali, izinto eziqandisiwe) | 1.35–1.50 | I-coefficient ephezulu yokungqubuzana; Kunconywa umkhawulo ongu-35-50% |
| I-Viscous, slurry, noma imidiya yokushisa ephezulu (>180°C) | 1.50–1.60 | Kubangela ukwanda kokungqubuzana emazingeni okushisa aphezulu kanye nokungena kwezinhlayiya endaweni yokuxhumana kwesihlalo |
| Isevisi enzima (ama-slurry arhabaxayo, izinsizakalo zokupheka, ukugibela ibhayisikili okuvamise kakhulu) | 1.60–1.80 | Xhumana nefektri ukuthola idatha ye-torque ethile yohlelo lokusebenza |
Ukubalwa Kwesampula Ye-Torque
Kunikezwe:
- Ivalvu yebhola yekilasi lama-300 enama-three-way engu-4″, umklamo we-PTFE onezihlalo ezi-4
- I-torque yokuqhekeka kwesisekelo somkhiqizi (Tb) ku-600 psi ΔP: 450 N·m
- Isevisi: Amanzi acwengekile ku-120°C (awagcobi)
- I-SF Enconyiwe: 1.40
I-Ta = 450 × 1.40 = 630 N·m i-torque encane ye-actuator
Khetha i-actuator:630 N·m × 1.05 (isici sokusebenza kahle kwesixhumi esisebenzisana ne-actuator-to-valve) =662 N·m → Khetha usayizi olandelayo ojwayelekile we-actuator: imodeli engu-700 N·m noma engu-800 N·m
Ukukhetha Ukuhamba kwe-Actuator ye-Pneumatic
| Uhlobo lwe-Actuator | I-engeli yokuhamba | Isicelo |
|---|---|---|
| Ukusebenza Okubili okungu-90° (i-Rack ne-Pinion) | 90° | Ukushintshwa okujwayelekile kwe-L-port; i-T-port eyisisekelo enezindawo ezimbili (ukuxuba noma ukuphambukisa) |
| 90° Ukubuya Kwentwasahlobo (Ukuphepha Okungaphumeleli) | 90° | Izinhlelo zokusebenza ze-L-port ezidinga indawo ephephile (entwasahlobo-ekuvaleni noma entwasahlobo-ekuvula) |
| Ukusebenza Okubili okungu-180° (i-Scotch Yoke) | 180° | Ama-valve e-T-port asebenzisa zonke izikhundla ezintathu zokusebenza (i-Center-Off / Left-Divert / Right-Divert) |
| I-Actuator Yezikhundla Ezi-3 Ene-Center-Off | 90° + 90° | Izinhlelo zokusebenza zokuxuba ezikhethekile ezidinga isikhundla esiphakathi "esivaliwe konke" |
Izinga Elibhekiselwe Kulona:Zonke izixhumi zokufaka ze-actuator kufanele zivumelaneI-ISO 5211(ubukhulu bephedi yokufaka ngqo kanye nosayizi wesikwele sesiqu). Lokhu kuqinisekisa ukushintshana phakathi kwabakhiqizi be-actuator futhi kwenza kube lula ukushintshwa kokulungiswa kwesikhathi esizayo.
6Izindlela Ezinhle Zokufaka: Ukuvimbela I-Water Hammer kanye Nokusiza Ekushiseni
Ukuvimbela I-Water Hammer Ngesikhathi Sokusebenza Ngesivinini Esiphezulu
Ukushintsha okusheshayo komoya (izikhathi zokushaya ngaphansi kwemizuzwana engu-0.5) kuma-valve amakhulu anama-three-way kungadala imithwalo yokushaqeka okukhulu kwe-hydraulic ngenxa yokwehla kokugeleza okusheshayo. Izingcindezi zesando samanzi ezimweni ezimbi kakhulu zingafinyelela ingcindezi yokusebenza evamile engu-5-10×, okungase kubangele:
- Ukufuduka kokusekelwa kwamapayipi
- Ukukhishwa kwe-Flange gasket
- Umonakalo wesiqu se-valve noma isihlalo
- Ukwehluleka kwethuluzi elingezansi
Isixazululo Sobunjiniyela:

- Lungisa isikhathi sokushaya sibeImizuzwana emi-2–5kuye ngobukhulu bomugqa kanye nesivinini sokugeleza
- Uma ufuna osayizi bomugqa ≥ 6″ noma ijubane ≥ 3 m/s, xhumana nomkhiqizi wamavalvu ukuze uthole izincomo zesikhathi sokushaya kwenhliziyo.
Ukukhululeka Kokukhuliswa Kokushisa Ezinhlelweni Zokushisa Okuphezulu
Ezindaweni zokushisa okuphezulu (ngaphezu kuka-200°C), uketshezi oluvaleleke ngaphakathi komgodi ofile we-ball port ehlukanisiwe lungakhula ngokushesha. I-volumetric expansion coefficient yama-hydrocarbon amaningi ku-200°C ingabangela ukucindezela koketshezi oluvalelekile kudlule i-10,000 psi—okungenzeka kuqhume ibhola noma kuphambukise umzimba we-valve.
Izidingo Zokuklama:
- Cacisa ama-valve anawoizihlalo zokukhulula umgodi(imigoqo yesihlalo esizikhululayo)
- Qinisekisa ukuthi ukwakheka kwesihlalo kuvumela uketshezi oluvalelekile ukuthi luphume luye ohlangothini olungezansi (umfutho ophansi) lapho umfutho udlula umthwalo wesihlalo obekwe kusengaphambili
