Pnevmatik boshqaruv klapanining ishlash printsipi bo'yicha qisqacha tahlil

Pnevmatik boshqaruv valfi asosan ikki qismdan iborat: aktuator va vanve organi. The actuator receives the air pressure signal from the controller (usually 3-15PSI or 6-30PSI), converts it into mechanical displacement, and then drives the valve body to change the flow cross-sectional area, thereby achieving precise control of fluid flow, pressure or liquid level and other parameters. Uning ish oqimlari quyidagilarni o'z ichiga oladi: signalni qabul qilish, bosimni qabul qilish, valfning harakatlanishi va valfi qayta ishlash parametrlari belgilangan qiymatga yaqin ekanligiga ishonch hosil qilish uchun yopiq-quruq nazoratni shakllantirish.
