Hluav taws xob tswj Valve
Cov yam ntxwv ntawm cov hluav taws xob tswj valve
1. Lub servo amplifier txais kev sib sib zog nqus tawm tswv yim tsis zoo, uas tuaj yeem txhim kho qhov tseeb ntawm kev hloov kho tsis siv neeg.
2. Cov neeg siv hluav taws xob tuaj yeem ua ntau hom thiab haum rau 4 ~ 20mA. DC los yog 0 ~ 10mA.
3. Lub adjustable ntau yam yog loj, qhov inherent adjustable ratio yog 50, thiab cov yam ntxwv ntws muaj xws li cov kab ncaj nraim thiab sib npaug feem pua.
4. Lub tshuab hluav taws xob tswj hluav taws xob tuaj yeem tswj tau lub valve ncaj qha los ntawm cov teeb liab tam sim no yam tsis tas yuav muaj lub servo amplifier.
5. Lub valve lub cev yog tsim raws li lub hauv paus ntsiab lus ntawm cov dej mechanics nrog ib tug tsawg-flow kuj passage sib npaug zos cross-section, thiab cov rated flow coefficient yog nce los ntawm 30%.

Regulating valve, tseem hu ua tswj valve, yog cov cuab yeej siv hluav taws xob ua haujlwm los hloov cov dej ntws hauv cov txheej txheem txheej txheem. Lub International Electrotechnical Commission (IEC) txhais lub regulating valve [hu ua Control Valve txawv teb chaws] raws li: "Nws muaj xws li ib tug net tivthaiv, ib tug sab hauv valve lub cev tivthaiv uas hloov tus khiav tus nqi ntawm cov txheej txheem kua, thiab ib los yog ntau tshaj actuators.
Tus actuator yog siv los teb rau cov teeb liab xa los ntawm kev tswj xyuas. Lub regulating valve yog tsim los ntawm ib tug actuator thiab ib tug valve tivthaiv. Lub actuator yog tus tsav tsheb ntawm lub regulating valve. Nws tsim cov kev sib tw sib tw raws li lub teeb liab siab, ua rau lub laub pas nrig txav mus ib ntus, yog li tsav lub valve tseem ceeb ntawm cov tswj valve kom txav mus. Lub valve tivthaiv yog lub regulating ib feem ntawm lub regulating valve. Nws ncaj qha cuam tshuam nrog qhov nruab nrab los ntawm kev hloov pauv ntawm tus actuator laub pas nrig kom hloov qhov throttling cheeb tsam ntawm regulating valve kom ua tiav lub hom phiaj ntawm kev cai. Regulating li qub feem ntau muab faib ua pneumatic regulating li qub, hluav taws xob tswj li qub thiab hydraulic regulating li qub raws li lawv lub zog. Qhov txawv yog nyob rau hauv lub actuator lawv nruab nrog. Lub pneumatic tswj valve siv compressed cua raws li lub hwj chim qhov chaw thiab yog nruab nrog ib tug pneumatic actuator. Lub tshuab hluav taws xob tswj valve siv hluav taws xob raws li lub zog hluav taws xob thiab nruab nrog lub tshuab hluav taws xob; hydraulic tswj valve siv hydraulic siab raws li lub hwj chim qhov chaw thiab yog nruab nrog ib tug hydraulic actuator.
Raws li kev xav tau, lub valve tswj tau tuaj yeem nruab nrog ntau yam khoom siv los ua kom yooj yim siv thiab ua tiav ntau dua hauv kev ua haujlwm. Cov khoom siv no suav nrog valve positioners, handwheel mechanisms, hluav taws xob converters, thiab lwm yam.

Ua hauj lwm hauv paus ntsiab lus ntawm hluav taws xob tswj valve
Lub tshuab hluav taws xob tswj lub valve tuaj yeem tswj qhov qhib ntawm lub valve raws li lub teeb liab los ntawm kev tswj hwm, yog li tswj qhov nruab nrab ntws, siab thiab qib kua. Kev siv ntau tshaj plaws 4-20mA tam sim no teeb liab ua piv txwv, thaum lub teeb liab los ntawm kev tswj hwm mus rau hluav taws xob tswj valve yog 4mA, lub valve tswj tau nyob rau hauv lub xeev kaw tag nrho, thiab thaum lub teeb liab 20mA muab rau nws, tswj valve yog nyob rau hauv ib tug tag nrho qhib lub xeev. Cov teeb liab sib txawv ntawm 4-20mA sib haum rau qhov sib txawv ntawm qhov kev tswj lub valve, uas yog, thaum lub kaw lus tswj muab nws lub teeb liab 12mA, qhov qhib ntawm lub regulating valve yog 50%. Xaiv qhov tsim nyog txaus coefficient raws li koj tus kheej qhov kev ua haujlwm nruab nrab, thiab koj tuaj yeem suav tus nqi ntws thiab siab sib haum rau txhua qhov qhib ntawm lub valve. Yuav kom ua tiav cov kev cai ntawm kev tswj lub valve rau qhov nruab nrab ua haujlwm.
