Backflow Preventer Riantuannak Phunglam

TWS hnulei kirnak khamnakcu a thurhnawmmi ti asiloah a dang thilri hna kha din khawhmi ti peknak system asiloah a thiangmi ti system chungah a hnulei in a luangmi khamnak caah sermi seh thilri a si, cu nih cun a hrampi system himnak le thianhlimnak kha a hngalhter. A riantuan ning phunglam cu a bik in fonhmi cungah aa hngatcheck valves, hneknak thleidannak mechanism, le a caancaan ah hnulei luannak dohnak caah “khamnak” sernak caah bawmhnak valve hna. A tlingmi tthennak cu hihi a si:

Dual Check ValveRiantuan ning
Tam deuhhnulei luannak khamnakaa pehtlaimi in chiahmi mah tein rian a ttuanmi check valve pahnih fonh. A hmasa bik check valve (inletcheck valve). Pahnihnakcheck valve(chuahnak awngcheck valve) nih a pahnihnak dawnkhantu rian a ttuan: a hmasa bik a si ahcuncheck valvea tlamtlin lo ahcun, a pahnihnak cu a tangmi hnulei luannak vialte kham awkah a cawlcang, a herh lomi huhphenhnak tthen a pek.

Pressure thleidannak zohkhenhnak
An pahnih karlak ahcheck valves, pressure thleidannak khaan (asiloah a karlak hmun) a um. A ttha tein riantuannak ah, luhnak lei (a hmasa bik check valve cunglei) i a ummi hneknak cu a karlak hmun i a ummi hneknak nakin a sang deuh, cun a karlak hmun i a ummi hneknak cu a chuahnak lei (a pahnihnak a tanglei lei) nakin a sang deuhcheck valve). Hi hneknak thlennak nih hin check valve pahnih cu a on peng hna, hmailei ah a luang kho.

Backflow a nai cang ahcun (tahchunhnak ah, tiva cunglei thli a tlak ruangah asiloah tiva tanglei thli a kai caah), thli tlukruannak cu a rawk. A hmasa bik check valve cu a karlak hmun in luhnak lei ah a kir tthan lonak hnga a khar. A pahnihnak check valve zong nih a hnulei hneknak a hmuh ahcun, a chuahnak lei in a karlak hmun ah a kir tthanmi kha kham awkah a khar.

Bawmhnak Valve Rianternak
Backflow khamnak tampi cu a karlak hmun he aa pehtlaimi bawmhnak valve he an i tlum. Check valve pahnih an rawk ahcun asiloah a karlak hmun i a ummi hneknak nih luhnak hneknak a lonh ahcun (a hnulei ah a luang khomi ttihnung a langhter), a karlak hmun i a thurhnawmmi ti kha thli (asiloah ti chuahnak system) ah chuahter awkah relief valve cu aa hun. Mah nih hin a thurhnawmmi ti kha ti thiang chuahnak ah a kirter lo, a hrampi system a fekmi a kilven.

Mah tein Riantuannak
A dihlak in a kalning cu amah tein a si, kut in hnahnawhnak a herh lo. Mah thilri nih hin ti tthawnnak le a luannak lamthluan thlennak kha a tthawng tein a lehrulh, riantuannak thil sining aa dangmi tangah a kir tthannak in pehzulh tein huhphenhnak a pek.

Backflow khamnak hna i ṭhatnak

Backflow khamnaka thurhnawmmi asiloah duhlonak a ummi thilri pawl a hnulei in a luannak khamnak thawngin ti dinnak thilri pawl, a hleiin din khawhmi ti thilri pawl kilvennak ah a biapi tukmi rian an ttuan. An tthatnak bik hna cu:

1. **Ti tthatnak kilvennak**

A biapi bikmi ṭhatnak cu din khawhmi ti le din awk a si lomi (tahchunhnak ah, riantuannak ti thurhnawm, ti thletnak ti, asiloah ti thurhnawm) karlak ah thurhnawmhnak a kham khawh. Mah nih hin dinmi ti asiloah a thiangmi thilri hna cu a thurhnawm lo nakhnga a bawmh, a thurhnawmmi ti hmannak he aa pehtlaimi ngandamnak ttihnung a zorter.

2. **Phunglam Zulhphung**

Ramkulh tam deuh ahcun, ti luannak khamnak hna cu ti luhchuahnak phunglam le ngandamnak phunglam (EPA asiloah khuachung ti nawlngeitu hna nih an chiahmi bantuk) nih a fial hna. An chiahnak nih thilri le system pawl kha upadi nih a herhmi a tlinter hna, dantatnak asiloah riantuannak kharnak hrial khawhnak a bawmh hna.

3. **A herh lomi le zumhawktlak sinak**

Tam deuhhnulei luannak khamnakcheck valve pahnih le bawmhnak valve a ngeih, a herh lomi himnak system a ser. Thilri pakhat a rawh ahcun, a dang nih backup ah an ṭuan, hnulei kirnak ttihnung kha a zorter. Hi suaisam nih aa thleng lengmangmi hneknak asiloah a luannak dirhmun tangah hmanh ah aa khatmi riantuan ning a hngalhter.

4. **Application kip ah hman khawhnak**

Innchungkhar, chawlehthalnak, riantuannak le khuabawi hna telh in hmunhma phunphun ah an i remh khawh. Plumbing network, ti ​​thletnak system, asiloah industry process line ah hmanmi a si zongah, backflow preventers nih hin ti phun (ti, chemical, tbk.) asiloah system ngan le hme zoh loin backflow kha ttha tein a kham.

5. **Thilri rawhnak tlawmternak**

A hnulei luannak kha ngolternak thawngin, hnulei luannak khamnak nih pump, boiler, ti lumternak, le a dang system thilri pawl kha backpressure asiloah ti hammer (ruah lo piin pressure a kai) nih a chuahtermi rawhralnak in a huhphenh hna. Mah nih thilri nunchung a sauter i zohkhenhnak man a zorter.

6. **Mah tein Riantuannak**

Backflow khamnakkut in hnahnawhnak um loin riantuan, hneknak thlennak asiloah luannak thlennak ah a rannak in a lehrulh. Mah nih hin minung zohkhenhnak cungah i hngat loin pehzulh tein kilvennak a pek, cu nih cun minung um lomi asiloah hlatpi in a ummi system caah aa tlakmi a siter.

7. **Man-Tlawmternak**

A hramthawk ah chiahnak man a um ko nain, caan sau caah tangka khonmi cu a tam ngai. Ti thurhnawmhnak thianhnak, thilri remhnak, phunglam ningin dantatnak, le thurhnawmhnak ti he aa pehtlaimi ngandamnak kong he aa pehtlaimi thil sining hna he aa pehtlaimi hmanmi phaisa kha an zorter. A sullam cu, backflow khamnak hna cu ti-hram bunhmi hmannak phunphun ah system tthatnak, mipi ngandamnak le riantuannak tthatnak kilvennak caah a herhmi an si.
