I-valve positioner sisetjenziswa esiyinhloko se-pneumatic actuators. Isetjenziswa ngokubambisana nama-pneumatic actuators ukwenza ngcono ukubekwa kwamavalvu nokunqoba imiphumela yokutjhayisana kwesiqu kanye namandla angalinganiko avela phakathi, ukuqinisekisa bona ivalvu ibekwe ngokunembileko ngokuya ngeempawu ezivela kumlawuli.

Isibekisi kufanele sisetjenziswe ebujamweni obulandelako:

Lokha umfutho ophakathi uphezulu begodu kunomehluko omkhulu womfutho.

Lokha ubukhulu bevalvu bukhulu (DN > 100).

Emavalvu wokulawula amazinga womtjhiso aphezulu nofana aphasi.

Lokha nakunesidingo sokwandisa ijubane lokusebenza kwevalvu yokulawula.

Lokha nawusebenzisa amatshwayo ajwayelekileko begodu usebenzisa amabanga angakajayeleki (amabanga angaphandle kwebanga lama-20 ukuya ku-100KPa).

Lokha nayisetjenziselwa ukulawula ngezigaba.

Lokha nakufezwa isenzo sevalvu esibuyela emuva (isib., ukutjhugulula hlangana nokuvala umoya nokuvulwa ngomoya).

Lokha nakunesidingo sokutjhugulula ubujamo bokugeleza kwevalvu (i-cam yokubeka ingalungiswa).

Lokha nakungekho umtjhini we-spring nofana umtjhini we-piston begodu isenzo esilinganako siyatlhogeka.

Lokha nakusetjenziswa ama-actuator we-pneumatic ngamatshwayo kagesi, kufanele kusetjenziswe isibekisi sevalvu yomoya kagesi.

Ivalvu ye-solenoid:

Lokha ihlelo nalitlhoga ukulawulwa kwehlelo nofana ukulawulwa kokuvula nokuvala, kusetjenziswa amavalvu we-solenoid. Lokha nawukhetha i-solenoid valve, ngaphandle kokucabangela i-AC nofana i-DC yamandla, ivoltheji, kanye nefrikhwensi, kufanele kutjhejwe ubudlelwano obusebenzako hlangana ne-solenoid valve ne-control valve. Kungaba mhlobo ovulekileko namkha ovalekileko. Nangabe kuyatlhogeka ukwandisa amandla we-solenoid valve ukunciphisa isikhathi sokuphendula, ama-solenoid valve amabili angasetjenziswa ngokufanako nofana i-solenoid valve ingasetjenziswa njenge-pilot valve ngokuhlanganiswa ne-pneumatic relay enekhono elikhulu.

I-Pneumatic Relay:

I-pneumatic relay yi-amplifier yamandla engadlulisa amatshwayo we-pneumatic eendaweni ezikude, ukuqeda ukulibaziseka okubangelwa maphayiphi wesignali amade. Isetjenziswa khulu hlangana nama-transmitter wesimu kanye namagumbi wokulawula aphakathi wokulawula iinsetjenziswa, nofana hlangana nabalawuli namavalvu wokulawula wesimu. Godu inomsebenzi wokukhulisa nofana ukwehlisa amatshwayo.

Umtjhugululi:

Iintjhugululi zihlukaniswe zaba zitjhugululi ze-pneumatic-gezi kanye nama-converter kagesi-wegezi. Umsebenzi wazo kukutjhugulula hlangana namatshwayo we-pneumatic newegezi ngokuya ngobudlelwano obuthileko. Zisetjenziswa khulu lokha nakusetjenziswa iinsetjenziswa zomoya ezinamatshwayo kagesi, ukutjhugulula amatshwayo kagesi we-0-10mA nofana we-4-20mA abe ziimpawu zombane ze-0-100KPa nofana ngokuphambene nalokho, ukutjhugulula amatshwayo wegezi we-0-10mA nofana we-4-20mA.

Umlawuli wesihluzo somoya:

Iinlawuli zokuhlunga umoya ziinsetjenziswa ezisetjenziswa eensetjenzisweni zokuzenzakalela zebubulo. Umsebenzi wazo omkhulu kukuhlunga nokuhlanza umoya ogandelelweko ukusuka kumakhompyutha womoya begodu uqinise umfutho ngenani elitlhogekako. Zingasetjenziswa njengemithombo yegesi kanye namadivayisi wokuqinisa umfutho weensetjenziswa ezihlukahlukeneko zomoya, amavalvu we-solenoid, amasilinda, imitjhini yokufafaza, namathulusi amancani womoya.

Ivalvu yokuzikhiya (Ivalvu yokukhiya indawo):

Ivalvu ezizikhiyako mtjhini osetjenziselwa ukugcina ubujamo bevalvu. Lokha ivalvu yokulawula umoya nayihlangabezana nokuhluleka ekuphakeleni komoya, idivayisi le ingavala isignali yomoya, igcine isignali yomfutho egumbini le-diaphragm nofana isilinda isesimeni sangaphambi kokwehluleka. Lokhu kuqinisekisa bona ubujamo bevalvu bugcinwa endaweni yangaphambi kokwehluleka, okwenza umnqopho wokukhiya ubujamo.

Isithuthi sendawo yevalvu:

Lokha ivalvu yokulawula nayikude negumbi lokulawula begodu kuyatlhogeka ukwazi kuhle ubujamo bevalvu ngaphandle kokuya esimini, kufanele kufakwe isitjhugululi sendawo yevalvu. Itjhugulula ukufuduswa kwendlela yokuvula ivalvu ibe siginali kagesi ngokuya komthetho othileko bese ithumela egumbini lokulawula. Itshwayo leli lingaba litshwayo eliragela phambili elitjengisa nanyana ngikuphi ukuvulwa kwevalvu, nofana lingathathwa njengesenzo esiphikisako sesibeki sevalvu.

Iswitjhi yokuTjhugulula (Idivayisi yokuphendula ngendawo):

Iswitjhi yokukhamba itjengisa iindawo ezimbili eziphakemeko zevalvu begodu ngasikhathi sinye ithumela isiginali yokutjengisa. Igumbi lokulawula linganquma ubujamo bokuvula nokuvala kwevalvu ngokuya ngesiginali le begodu ithathe amagadango ahambelana nawo.

I-Tianjin Tanggu Water-Seal Valve Co.,ltdzisekela ithekhnoloji ethuthukileko khulu yamavalvu ahlala aqinileko, kufaka hlangana amavalvu ahlala aqinilekoi-wafer butterfly valve, Ivalvu ye-Lug butterfly, Ivalvu yevithamini ye-flange ephindwe kabili, Ivalvu ye-butterfly ye-flange ephindwe kabili, I-Y-strainer, ivalvu yokulinganisa, ivalvu yokuhlola amapuleti amabili we-Wafer, njll.
