Fitinglar chizmasini bajarish. Fitinlarning ko‘rinishlarini chizishda oldin fitinglardan biri, masalan, o‘tish muftasining rezbali diametrlari d, d1 va uzunligi
L hamda qovurg‘alar soni, elementlarining o‘lchamlari chizmachilik ma’lumotnomasidagi jadvallardan foydalanib chiziladi. 5.34-rasmda biriktiruvchi to‘g‘ri muftaning chizmasi berilgan bo‘lib, uning qismi, shakli va konstruktiv o‘lchamlarini 5.3-jadvaldan olinadi.
5.34-rasm Biriktiruvchi fitinglarning yaqqol tasvirlari va ortogonal proyeksiyalari 5.35-
rasmda berilgan. Uning o‘lchamlari ham 5.3-jadvaldan olinadi.
