Intelligent Valve electro-pneumatic Positioner
Valve positioner , iyo huru yevhavhavha inogadzirisa, iyo yevhavha yevhavha ndiyo inonyanya kushandiswa yevhavha inogadzirisa, iyo inoshandiswa kudzora dhigirii yekuvhura yepneumatic kana yemagetsi valve kuti ive nechokwadi chokuti valve inogona kumira zvakarurama kana inosvika kune yakafanotemerwa. chinzvimbo. Kuburikidza nekutonga kwakanyatsoita kwevhavha positioner, kunyatsogadziriswa kwemvura kunogona kuwanikwa kuzadzisa zvinodiwa zvakasiyana-siyana zvemaindasitiri. Mavharuvhu ekuisa mavharuvhu akakamurwa kuita pneumatic valve positioners, electro-pneumatic valve positioners uye akangwara mavharuvhu chinzvimbo zvinoenderana nechimiro chazvo. Ivo vanogashira chiratidzo chinobuda cheiyo regulator vobva vashandisa iyo inobuda chiratidzo kudzora iyo pneumatic inodzora vharafu. Kutamiswa kwechidzitiro chevharuvhu kunodzoserwa kuchigaro chevharuvhu kuburikidza nemuchina wemuchina, uye chinzvimbo chevharuvhu chinotapurirwa kuhurongwa hwepamusoro kuburikidza nechiratidzo chemagetsi.Pneumatic valve positioners ndiyo inonyanya kukosha mhando, kugamuchira uye kudyisa kumashure masaini kuburikidza nemichina michina.
Iyo electro-pneumatic valve positioner inosanganisa magetsi uye pneumatic tekinoroji kuvandudza iko kurongeka uye kuchinjika kwekutonga.
Iyo yakangwara vharafu chinzvimbo inounza microprocessor tekinoroji kuti iwane yakakwirira otomatiki uye nehungwaru kutonga.
Valve positioners vanoita basa rakakosha mumaindasitiri otomatiki masisitimu, kunyanya mumamiriro ezvinhu anodiwa kunyatso kudzora kuyerera kwemvura, senge maindasitiri emakemikari, peturu, uye gasi rechisikigo. Vanogashira masaini kubva kuhurongwa hwekutonga uye kunyatsogadzirisa kuvhurwa kwevhavha, nekudaro vachidzora kuyerera kwemvura uye kusangana nezvinodiwa zveakasiyana maindasitiri maitiro. -
muganhu chinja bhokisi-Valve Position Monitor -kufamba chinja
The valve limit switch box, inonziwo Valve Position Monitor kana valve yekufamba chinja, chinhu chinoshandiswa kuona nekudzora nzvimbo yekuvhura nekuvhara yevhavha. Yakakamurwa kuita michina uye yepedyo mhando. modhi yedu ine Fl-2n, Fl-3n, Fl-4n, Fl-5n. Muganhu chinja bhokisi kuputika-uchapupu uye mazinga ekudzivirira anogona kusangana nepasi-yemhando zviyero.
Mechanical muganho switch inogona kukamurwazve kuita yakananga-kuita, rolling, micro-kufamba uye akasanganiswa marudzi zvinoenderana neakasiyana maitiro modes. Mechanical valve limit switch inowanzo shandisa micro-motion switch ine passive contacts, uye mafomu avo ekuchinja anosanganisira single-pole double-throw (SPDT), single-pole single-throw (SPST), nezvimwewo.
Proximity limit switch, inozivikanwawo senge isingabatike yekufamba switch, magineti induction valve limit switch inowanzo shandisa electromagnetic induction proximity switch ine passive contacts. Mafomu ayo ekuchinja anosanganisira single-pole kaviri-kukanda (SPDT), single-pole single-kukanda (SPST), nezvimwe.
