TWS Backflow Preventor

Cik mi tic pa Backflow Preventer

TWS backflow preventerutiye jam tic moko ma juyike pi juku mol pa pii ma cido nyo piny mukende i pii ma jumadhu nyo i pii maleng, ma ketho bedo maleng man maleng pa piny ma pire tek. Tic pare ucungo iwi rwom panen valves, yore mi poko kero, man kare mukende relief valves mi cwio "barrier" ikum backflow. Kae utiye poko lembe:

Dual Check ValveYore
Mapol neju ma juku dwoko cenmed check valves ario ma timo tic giri giri ma juketho i rwom acel. Valve mir acel mi neno (inletcheck valve). Mir aryocheck valve(kare mi wokcheck valve) timo tic calu jamb cing mir aryo: ka mir acelcheck valveka epodho, mir aryo timo tic mi juku backflow moko ci ma udong, ma miyo gwok ma rwinyo.

Lubo tung tung pa tegu
Ikind lembe aryo eninen valves, utiye kabedo ma tung tung pa pressure (nyo kabedo ma ikin piny). I tic maber, tegu ma nwang i thenge mi donjo (ma malu pa check valve mir acel) utiye malo uloyo tego ma ni i thenge ma ikin, man tego ma i thenge ma ikin utiye malo uloyu i thenge ma wok woko (piny pa valve mir aryocheck valve). Gradient pa pressure eni ketho check valves ario zoo bedo ma oyabere, miyo pii mol anyim.

Ka backflow ubetimere (e.g., pi rwinyo pa pressure ma malu nyo mediri pa pressure ma piny), rwom pa pressure ubedo marac. Valve mir acel cego pi juku pii ma wok kud i kind piny ni dhugola. Ka check valve mir aryo de unwangu reverse pressure, ecego pi juku dwoko cen kud i thenge mi wok ni thenge mi dyere.

Relief Valve Activation
Jam tic mapol ma juku pii ma wok kud i ngeye gitiye ku relief valve ma juketho i kind zone. Ka check valves ario zoo utur nyo ka pressure i kind zone ukadhu pressure mi inlet (ma nyutho nia copo bedu rac pa backflow), relief valve oyabere pi wodhu pii ma cido i intermediate zone i yamu (nyoke i drainage system). Eni juku pii ma cido ni dwogo i pii maleng, ma gwoko leng pa piny ma pire tek.

Tic ma timo kende
Lembe ceke utiye automatic, man epe ku cing. Jam tic ne dwoko wang lembe maber ni aloka loka pa tegu pa pii man yo ma pii mol kudu, ma miyo bedo maber ikum mol pa pii i thenge mi tic matung tung.

Ber pa ju ma gwoko pii ma wok cen

Jam juku dwoko centimo tic ma pire tek i gwoko pii, asaga pii ma madhu, ni juku mol pa piny ma rac nyo ma ber ongo. Ber migi madongo uketho i iye:

1. **Gwoko ber pa pii**

Ber pa piny ma pire tek utiye juku two ma rac ikind pii ma madhu ku pii ma madhu ngo (e.g., pii ma rac mi tic, pii mi pur, nyo pii ma rac). Eni ketho pii ma madhu nyo pii maleng ma jucwalo bedo maleng, ma jwigo peko mi yot kum ma bino pi madhu pii ma leng.

2. **Lubu cik**

I kabedu madwong, ju ma gwoko pii kud i pii juyike ku cik mi pii man cik mi yot kum (macalu ma ju ketho ku dilo macalo EPA nyo judongo pa pii). Kethu gi konyo kabedo man jam tic ni timo lembe ma cik mito, ni jwigo cul nyo juku tic.

3. **Redundancy man Reliability**

Mapol neju ma juku dwoko centiye ku valve aryo mi neno man valve mi dwoko piny, ma cwio yore mi gwoko kwo. Ka piny acel utur, mukende timo calu backup, ma jwigo peko mi backflow. Kit ma juyubu kudu eni ketho tic maber kadi i rwom ma malu pa pressure nyo flow conditions.

4. **Bedo ku tic matung tung**

Gicopo lokore i kabedo matung tung, ikinde utiye kabedo mi bedo, kabedo mi kuloka, kabedo mi tic, man kabedo mi adhura. Kadi bed jutiyo kudu i yore mi pii, yore mi pii, nyo yore mi tic mi cuma, piny ma juku pii ma mol cen gi gwoko pii ma mol cen labongo paro pi kit pii (pi, kemikol, man mukende mapol) nyo dit pa pii.

5. **Dwoko piny pa peko pa jam tic**

Ka juku pii ma dwoko cen, ju ma gwoko pii ma dwoko cen gwoko pump, boilers, heaters mi pii, man piny mukende ma tiyo kudu kud i peko ma wok kud i backpressure nyo water hammer (sudden pressure surges). Eni medu kwo pa jam tic man dwoko piny wel mi gwoko gi.

6. **Tic ma timo kende**

Jam juku dwoko centimo tic manangu cing timo ngo, dwoko wang lembe iwi aloka loka pa pressure nyoke flow reversals. Eni ketho bedo maber mandha labongo geno dhanu, ma weko gibedo ber pi dhanu ma dhanu ope i iye nyo kabedo mabor.

7. **Bedo maber**

Kadi bed ni wel mi caku kethu piny utiye, lim ma jugwoko pi kare malac utiye madit. Gidwoko piny wel piny ma jutiyo kudu pi yweyu pii ma cido, yiku jam tic, cul pa cik, man lembe ma copo wok ikum peko mi yot kum ma mako pii ma cido. I andha, ju ma gwoko backflow gibedo piny ma pire tek pi gwoko leng pa piny, yot kum pa dhanu, man tic maber ikind tic matung tung ma tiyo ku pii.
