Valve Positioner Configuration:

Valve positioners inogona kukamurwa kuitapneumatic valve positioners, electro-pneumatic Valve positioner uye yakangwara vharafu chinzvimbo zvinoenderana nechimiro chayo uye musimboti wekushanda.
Iyo valve positioner inogona kuwedzera simba rekubuda revhavha inogadzirisa, kuderedza kutakura lag yechiratidzo chekutonga, kukurumidza kufamba kwevhavhavhavha, kugadzirisa mutsara wevhavha, kukunda kukwesha kwevhavhavha uye kubvisa simba iyo isina kuenzana simba Kuti uve nechokwadi chekumisikidza kwakaringana kwevhavha yekudzora.

Valve Positioner Adapters:

Inowanzo shandiswa actuator pneumatic actuator, yemagetsi actuator, kune yakatwasuka sitiroko, angular sitiroko.Kuvhura otomatiki, bhuku rekuvhara nekuvhara marudzi ese emavharuvhu, ndiro yemhepo, nezvimwe.

Kushanda Nheyo yeValve Positioner:

Iyo valve positioner ndiyo inonyanya kushandiswa yevhavha yekudzora.Zvinotora iyo valve stem displacement chiratidzo seyekuisa mhinduro yekuyera chiratidzo, inotora iyo controller inobuda chiratidzo sechiratidzo chekumisikidza, inotakura pakuenzanisa, kana vaviri vacho vaine kutsauka, inoshandura chiratidzo chayo chekubuda kune iyo Executive mashandiro, inokonzera iyo Executive Meshini chiito. , iyo imwe-kune-imwe inonyorerana pakati pekusimuka kwakawanda kwevhavha stem uye chiratidzo chinobuda chemutongi chinotangwa.Naizvozvo, iyo vharafu inomira ine yevhavha stem displacement kuyerwa chiratidzo kune inobuda ye controller set chiratidzo mhinduro yekudzora system.Iyo control system's control variables ndiwo masaini anobuda evhavha positioner kune actuator.

Kukamurwa kweValve Positioners:

Valve positioner zvinoenderana nechiratidzo chekuisa yakakamurwa kuita pneumatic valve positioner uye yemagetsi valve positioner.Chiratidzo chepneumatic valve positioner chiratidzo chegasi, semuenzaniso, 20 ~ 100KPA gasi chiratidzo, chiratidzo chayo chekubuda chiratidzo chegasi.Magetsi valve positioner yekuisa siginecha ndiyo yakajairwa ikozvino kana voltage siginecha, senge 4 ~ 20mA yazvino chiratidzo kana 1 ~ 5V voltage siginecha, nezvimwe. Mumagetsi valve positioner inoshandurwa kuita magetsi emagetsi, siginecha yegesi inobva yabuda kune dial. control valve.
Zvinoenderana negwara rekuita rinogona kukamurwa kuita imwe-nzira vharafu chinzvimbo uye maviri-nzira vharafu chinzvimbo.Kana iyo yenzira imwe chete yevharuvhu ichishandiswa muPiston actuator, iyo vharafu inomira inoshanda munzira imwe chete, uye maviri-nzira vharafu chinzvimbo inoshanda mumativi ese episton actuator silinda uye munzira mbiri.

Zvinoenderana neiyo vharafu yekumisikidza inobuda uye yekupinza chiratidzo chekuwana zviratidzo zvakakamurwa kuita positive valve positioner uye negative valve positioner.Kana iyo yekuisa chiratidzo cheiyo positive-acting valve positioner ichiwedzera, chiratidzo chekubuda chinowedzerawo, kuitira kuti kuwana kwakanaka.Kana iyo yekuisa chiratidzo cheiyo counter-acting Valve positioner ichiwedzerwa, chiratidzo chekubuda chinoderedzwa uye, saka, kuwana kwakaipa.

Zvinoenderana nevhavha chinzvimbo chekuisa chiratidzo chiratidzo cheanalog kana chiratidzo chedhijitari, inogona kupatsanurwa kuita general valve positioner uye munda bhazi yemagetsi valve positioner.Chiratidzo chekupinza che general valve positioner is analog air pressure kana yazvino uye voltage sign, uye chiratidzo chekupinza chemumunda bhazi remagetsi valve positioner chiratidzo chedhijitari chebhazi remumunda.

Zvinoenderana nekuti iyo valve positioner ine CPU inogona kukamurwa kuita general electric valve positioner uye yakangwara yemagetsi valve positioner.Iyo general electric valve positioner haina CPU, saka, haina hungwaru uye haigone kubata kwakakodzera kwakangwara mashandiro.Iyo yakangwara valve inomira neCPU inokwanisa kubata yakangwara mashandiro, semuenzaniso, inogona kuita iyo isiri mutsara muripo weiyo yekumberi chiteshi, nezvimwewo. Munda bhazi electric valve positioner inogonawo kuita basa module sePID kuti ione kushanda kunoenderana. .
