Elektr qalpoqcha valf ta'rifi
Kelebek valve ning xususiyatlari mavjud oddiy struktura, kichik nuqta hajmi, engil og'irligi, past material iste'mol, kichik o'rnatish hajmi, tez o'tish, 90 daraja recipro burilish aylanishi, va kichik haydovchi torna. It ishlatiladi uchun kesilgan off 2c ulash, va tartibga laydi the orta in in the pipeline. It has Good flow control characteristics and shut-off sealing performance.

Boshqaruv printsipi of elektr kelebek valver
nazorat printsipi the electric butterfly valve is to control the switching of the valve disc through a motor to achieve flow regulation of liquid or gas. The specific control principle is as follows:
1. Motor control:
Elektr kelebek valflari boshqariladi motorlar, umuman yordamida DC motorlar yoki AC motorlar. Ko'ra the control signal, the motor rotates to open and close the valve disc, shu changlatish hajmi ning o'lchami suyuqlik kanali.
2. Qabul boshqaruv signallari:
Elektr kelebek vallar qabul olish tashqi boshqaruv signallari, odatda elektr signallari yoki pnevmatik signallar. Elektr signallari odatda analog signallar (masalan %{{ kabi 0}}mA) yoki raqamli signallar (masalan {0-5V), va pnevmatik signallar odatda havo bosimi signallari bo'ladi.
3. Lavozim fikr-mulohazalar:
Elektr kelebek valflari odatda jihozlangan bilan jihozlangan a pozitsiya fikr-mulohazalar uskuna to feedback the position information of the valve disc. Keng tarqalgan foydalaniladigan pozitsiya feedback uskunalar ichiga kiradi rotator pozitsiya sensorlar yoki Zal sensorlar. The position feedback device feeds back the valve disc position information to to control system to achieve precise valve control.
4. Boshqaruv tizimi:
elektr kelebek valning boshqaruv tizimi hisoblaydi the drive control signal of the motor orqali a control algoritm asosida olingan nazorat signal va pozitsiya fikr-mulohazalar signal, va boshqaruv uchun aylanish yo'nalishi va tezligi uchun motor to to erishish ochilish va yopish boshqaruvi val disk.
In summa, the control principle of the electric butterfly valve is to receive external control signals and position feedback signals through the control system%2 hisoblang disk disk control signal to the motor, shunday boshqarish uchun ochilish va yopish of of the valve disk va erishish suyuqlik oqimi tartibga solish.
