Pnevmatik kelebek klapanning umumiy ko'rinishi, pnevmatik kelebek klapan pnevmatik aktuator va kelebek valfdan iborat. Pnevmatik kelebek klapan ochish va yopish uchun valf novdasi bilan o'zgarib turadigan dumaloq kapalak plitasidan foydalanadi. Faollashtirish harakatini yakunlash uchun pnevmatik klapan asosan o'chirish{0}}valfi sifatida ishlatiladi va u shuningdek, jo'natish yoki qism vana va jo'natish ta'siriga ega bo'lishi uchun mo'ljallangan bo'lishi mumkin. Hozirgi vaqtda kelebek klapan yuqori bosim ostida. Katta va o'rta diametrli quvurlardan foydalanish ortib bormoqda. Pnevmatik kelebek klapan tasnifi, zanglamaydigan po'latdan yasalgan pnevmatik kelebek klapan, qattiq muhrlangan pnevmatik kelebek klapan, yumshoq muhrlangan pnevmatik kelebek klapan, karbonli po'latdan yasalgan pnevmatik kelebek klapan.
Pnevmatik kelebek klapanning ishlash printsipi pnevmatik aktuator va kelebek valf ulanishidan iborat. Pnevmatik kelebek klapan siqilgan havo orqali pnevmatik aktuatorga tiqilib, dumaloq kapalak plitasini 90 graduslik aylanish harakati qilish uchun harakatga keltiradi, bu quvur liniyasini o'zgartirish va tartibga solish oqimi sifatida ishlatiladi. Pnevmatik kelebek klapan ish printsipi sifatida 0-90 darajagacha ochiladi va yopiladi. Ya'ni, 0 daraja to'liq yopiq holat, 90 daraja esa to'liq ochiq holat. Pnevmatik aktuatorga joylashtiruvchi qo'shing va mos keladigan signalni kiriting va kelebek valf plitasi o'zboshimchalik bilan 0 dan 90 darajagacha sozlanishi mumkin. Pnevmatik gofretli kelebek klapan aktuatori boshqaruv ma'lumotlarini qabul qiladigan va avtomatlashtirilgan texnik vositalarda boshqariladigan ob'ektlarga boshqaruv effektlarini qo'llaydigan qurilma. Amaldagi harakatlantiruvchi energiyaga ko'ra, aktuatorlar pnevmatik, elektr va gidravlik aktuatorlarga bo'linadi. Elektr aktuatorlari va pnevmatik aktuatorlar hozirgi asosiy aktuatorlardir.
Pneumatic butterfly valve adopts the new series GT type pneumatic actuator, with double effect type and single effect type (spring reset), gear transmission, safe and reliable; large diameter valve adopts series AW type pneumatic actuator fork type transmission, reasonable structure, output Large torque, there are double-effect type and single-effect type. Pneumatic butterfly valve gear type double piston, large output torque and small volume. The cylinder is made of aluminum and gold material, which is light in weight and beautiful in appearance. Manually operated tissue can be installed on top and bottom.
Pnevmatik kelebek klapanning kukunli tizimi uchun boshqa omillarni hisobga olish kerak, masalan: material yuqoridan trolleybusga qo'yilganda, uni to'g'ridan-to'g'ri valfning valf plitasiga shoshilib bo'lmaydi (bu zarba kuchi shuningdek, valfni mahkam yopilmasligiga olib keladi) va material Vana statik bosimi ham pnevmatik kelebek klapanning mo'ljallangan yotqizish bosimidan oshmasligi kerak va hokazo.
The difference between the control valve and the general manual valve is that it cannot be regarded as an isolated component, but needs to be considered as part of the entire automatic control system. Many problems in the use of the control valve are not the selection and The problem of equipment is due to the lack of user's knowledge of the control valve, which causes the control valve to fail to debug and cooperate with the control system. As long as you know the key point of the problem, select the valve correctly, and debug the control valve in the system debugging stage, the failure rate will be greatly reduced, and the automatic control system will run stably for a long time.
