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.
