BAB 6 DETAIL JUNCTION

6.1 Simbol Yang Digunakan Aksesoris yang digunakan pada gambar detail junction umumnya digambarkan dengan simbol-simbol tertentu. Simbol dari detail junction yang digunakan dalam perencanaan ini dapat dilihat pada tabel dibawah. Tabel. 6.1 Simbol Detail JunctionNo Nama Fungsi

1 Tee All Flange

Digunakan bila ada 3 percabangan

2. CI Pipe with Flange

Digunakan bila ada 2 percabangan

3. Bend Flange 45o

Digunakan untuk belokan 450

4. Bend Flange 90o

Digunakan untuk belokan 900

Dipakai sebagai penyambung yang kuat dan 5. Giboult Joint fleksibel, agar mudah melepas aksesoris didekatnya bila ada kerusakan

6. Gate Valve

Mengatur debit air yang keluar/mengalir

7. Reducer

Untuk sambungan pipa diperbesar atau diperkecil

65 Arum Teja Asmara 3308100072


8. Flange with Thrust 9. Meter air

Sambungan pipa yang masuk tembok, agar pegangan pipa kuat pada tembok

Mengetahui besarnya debit air yang mengalir

6.2 Detail Junction Gambar detail junction menunjukkan jenis-jenis aksesoris yang digunakan pada tiap node yang ada pada jaringan pipa distribusi, yang dapat dilihat pada tabel 6.1 akan tetapi terlebih dahulu harus diketahui diameter dari tapping yang diinginkan, berikut adalah contoh diameter tapping untuk blok I (junctio N2): Debit ( Q ) Kecepatan pipa Diameter pipa ( D ) Diameter pipa ( D ) terpakai = 20,95 liter/detik = 0,02095 m3/detik = 0,75 m/detik4.Q .v = 160 mm
