"Ivalvu yebhabhathane eli-150" idla ngokubandakanya iiparameter ezimbini eziqhelekileyo:
- DN150: Ububanzi obuqhelekileyo yi-150mm (bulingana nee-intshi ezi-6 kwi-NPS).
- 150lb / 150 / Udidi lwe-150: Uvavanyo loxinzelelo lwe-ANSI/ASME Udidi lwe-150 (malunga ne-150 psi, oluqhelekileyo kwiinkqubo ezisemgangathweni zaseMelika, olulingana ne-PN20 eTshayina/eJamani).
1. Ubukhulu beValve yeBhabhathane ye-DN150 / 6"
Iintlobo zeevalvu zebhabhathane ziquka iWafer, iLug, kunye neDouble Flanged. Le datha ilandelayo ishwankathela iiparameter eziphambili ngokusekelwe kwimigangatho efana ne-ASME B16.5.
1.1 Uhlobo lweWafer/Lug (Uhlobo lweClip-on/Lug, uqhagamshelo oluqhelekileyo olufutshane, oluhambelana ne-ISO 5752):
Ubude boBuso ngoBuso: 55–57 mm
- Ubude obupheleleyo (umngxuma ongenanto ngaphandle kwe-actuator): 320–400 mm (ukusebenza okujonge phezulu/okuphezulu)
- Ubungakanani bomgodi:≈14*14mm
1.2 Uhlobo lweFlanged kabini (Uqhagamshelo lweFlanged kabini, oluhambelana ne-ISO 5752):
- Ubude boBuso noBuso: Malunga ne-140mm/210mm
- Ubude obupheleleyo (umngxuma ongenanto ngaphandle kwe-actuator): 410 mm/589mm (oyi-concentric/ophindwe kabini) 2. Iiparamitha ze-ASME B16.5 Class 150 Flange Basic (Isebenza kwi-NPS 6" / DN150)
Lo ngumgangatho woqhagamshelo lweflange yebhabhathane (Uhlobo lweWafer/Lug lufuna iflange yepayipi efanayo, uhlobo lweDouble Flanged luza neflange).
| Ipharamitha | Ixabiso (ii-intshi) | Ixabiso (mm malunga) | Amanqaku |
| Ububanzi obungaphandle beFlange (OD) | 11.00 | 279.4 | |
| Ububanzi beSangqa seBolt | 9.50 | 241.3 | |
| Inani leeBholti | 8 | – | |
| Ubungakanani beBolt | 3/4" | Ilingana ne-M20 | Imisonto ye-UNC 3/4"-10 |
| Ububanzi beBolt Hole | 0.88 | 22.2 | |
| Ububanzi bobuso obuphakanyisiweyo | 8.50 | 215.9 | Okuqhelekileyo kwiiflange zeRF |
| Ubukhulu beFlange (umzuzu) | 1.00 | 25.4 | Kubandakanya ubuso obuphakanyisiweyo |
3. Itshati yeFlange Bolt eyi-150 kunye neTorque
3.1Iinkcukacha zeBolt yeKlasi ye-150 NPS 6":
- Inani leeBholti: 8
- Ububanzi beBolt: 3/4"
- Ubude beStud Bolt obucetyiswayo (1/16" RF): Malunga ne-4 intshi (102 (mm)
I-torque ye-flange bolt ecetyiswayo yokufakela i-butterfly valve (emva kokuthambisa, ukuqinisa):
| Ubungakanani beValve | Ubungakanani beBolt | I-Torque encinci (ft-lb) | I-Max Torque (ft-lb) |
| 5"–8" | 3/4" | 30–40 | 100–120 |
3.2 Amanyathelo Okuqinisa (Ukuqinisa Ngokunqamlezayo):
a. Umjikelo Wokuqala: I-Torque engama-30%
b. Umjikelo Wesibini: I-60% Torque
c. Umjikelo Wesithathu: I-100% Torque
d. Umjikelo Wokugqibela: Jonga ngokwewashi/ngokuchasene newashi
