Malangizo
Vavu ya singano yapamwamba kwambiri imatha kugwira ntchito pamanja kapena yokha. Mavavu a singano ogwiritsidwa ntchito pamanja amagwiritsa ntchito gudumu lamanja kuti azitha kuwongolera mtunda pakati pa chopondera ndi mpando wa valavu. Gudumu lamanja likatembenuzidwa mbali imodzi, chopondera chimakwezedwa kuti chitsegule valavu ndikulola madzi kudutsa. Gudumu lamanja likatembenuzidwa mbali ina, chopondera chimayandikira mpando kuti chichepetse kuthamanga kwa madzi kapena kutseka valavu.
Ma valve odzipangira okha amalumikizidwa ku mota ya hydraulic kapena actuator ya mpweya yomwe imatsegula ndikutseka yokha valavu. Mota kapena actuator idzasintha malo a plunger malinga ndi nthawi kapena deta yakunja yogwira ntchito yomwe yasonkhanitsidwa poyang'anira makinawo.
Ma valve onse a Needle oyendetsedwa ndi manja komanso odziyimira pawokha amapereka ulamuliro wolondola wa kuchuluka kwa madzi omwe akuyenda. Gudumu lamanja lili ndi ulusi wabwino, zomwe zikutanthauza kuti limatenga nthawi zambiri kuti lisinthe malo a plunger. Chifukwa chake, valavu ya singano ingakuthandizeni kuwongolera bwino kuchuluka kwa madzi omwe akuyenda mu dongosolo.
Zida ndi Zithunzi za Valavu ya Singano
1. Valavu ya singano
2. Yopangidwa ndi chitsulo chosapanga dzimbiri ASTM A479-04 (Giredi 316)
3. Malekezero okhala ndi ulusi molingana ndi ASME B 1.20.1(NPT)
4. Kupanikizika Kwambiri Kogwira Ntchito 6000 psi pa 38 °C
5.Kutentha Kogwira Ntchito -54 mpaka 232°C
6. Chotsekera cha bonnet chachitetezo chimaletsa kutayika mwangozi.
7. Kapangidwe ka mipando yakumbuyo kamateteza kulongedza katundu pamalo otseguka kwathunthu.

Chithunzi cha Kutayika kwa Mutu wa Valavu ya Singano
Ma Valves a Singano Kuyeza Kutentha kwa Kupanikizika
MFUNDO ZA Kv
KV = Kuchuluka kwa madzi mu mita imodzi pa ola limodzi (m³/h) komwe kudzapangitsa kuti kupanikizika kuchepe ndi bala imodzi kudutsa valavu.

Zipangizo zolumikizira mapaipi ndi zinthu zofunika kwambiri mu dongosolo la mapaipi, zomwe zimagwiritsidwa ntchito polumikiza, kusinthira, kusintha kukula, kutseka kapena kuwongolera kayendedwe ka madzi. Zimagwiritsidwa ntchito kwambiri m'magawo monga zomangamanga, mafakitale, mphamvu ndi ntchito za m'matauni.
Ntchito Zofunika Kwambiri:Imatha kugwira ntchito monga kulumikiza mapaipi, kusintha njira yoyendera, kugawa ndi kuphatikiza madzi oyenda, kusintha mainchesi a mapaipi, kutseka mapaipi, kuwongolera ndikuwongolera.
Chiwerengero cha Ntchito:
- Kupereka madzi ndi ngalande m'nyumba:Zigongono za PVC ndi ma PPR tris amagwiritsidwa ntchito pa maukonde a mapaipi amadzi.
- Mapaipi a mafakitale:Ma flange achitsulo chosapanga dzimbiri ndi zigongono zachitsulo chopangidwa ndi alloy zimagwiritsidwa ntchito kunyamula zinthu zamagetsi.
- Kuyendera mphamvu:Mapaipi achitsulo amphamvu kwambiri amagwiritsidwa ntchito m'mapaipi amafuta ndi gasi.
- HVAC (Kutenthetsa, Kupumira mpweya, ndi Kuziziritsa Mpweya):Zipangizo za mapaipi a mkuwa zimagwiritsidwa ntchito polumikiza mapaipi oziziritsa, ndipo malo olumikizirana osinthasintha amagwiritsidwa ntchito pochepetsa kugwedezeka.
- Ulimi wothirira:Zolumikizira mwachangu zimathandiza kusonkhanitsa ndi kusokoneza makina othirira opopera madzi.
