TWS Backflow Preventer

Mfundo Yogwira Ntchito ya Backflow Preventer

TWS backflow preventerndi makina opangidwa kuti ateteze kutuluka kwa madzi oipitsidwa kapena zofalitsa zina kulowa m'madzi otsekemera kapena madzi oyera, kuonetsetsa chitetezo ndi chiyero cha dongosolo loyamba. Mfundo yake yogwirira ntchito imadalira kuphatikiza kwafufuzani ma valve, kukakamiza kusiyanitsa njira, ndipo nthawi zina ma valve operekera chithandizo kuti apange "chotchinga" motsutsana ndi kubwereranso. Nawu kulongosola mwatsatanetsatane:

Dual Check ValveNjira
Ambirizoletsa kubwereraphatikizani ma valve awiri odziyimira pawokha omwe amaikidwa pamndandanda. Chovala choyamba choyang'ana (inletchekeni valavu) amalola kuti madzi aziyenda patsogolo mu dongosolo pansi pazikhalidwe zabwinobwino koma amatseka mwamphamvu ngati kupsinjika kwa m'mbuyo kumachitika, kuteteza kubwereranso kumbuyo kuchokera kumbali yakumunsi. Chachiwirichekeni valavu(chotulukachekeni valavu) imakhala ngati chotchinga chachiwiri: ngati choyambachekeni valavuikalephera, yachiwiri imayambitsa kutsekereza kubwereranso kulikonse, kupereka chitetezo chokwanira.

Pressure Differential Monitoring
Pakati pa awiriwofufuzani ma valve, pali chipinda chosiyanitsira chokakamiza (kapena chigawo chapakati). Pantchito yanthawi zonse, kuthamanga kwa mbali yolowera (kumtunda kwa valavu yoyamba yoyang'ana) kumakhala kokulirapo kuposa kukakamiza kwapakati, ndipo kupanikizika m'dera lapakati ndikwambiri kuposa mbali yakutuluka (kumunsi kwachiwiri).chekeni valavu). Kuthamanga kumeneku kumatsimikizira kuti ma valve onse a cheki amakhalabe otseguka, kulola kuyenda patsogolo.

Ngati kuthamanga kwa m'mbuyo kuli pafupi (mwachitsanzo, chifukwa cha kutsika kwadzidzidzi kwa kuthamanga kwamtunda kapena kutsika kwa kuthamanga kwapansi), kuthamanga kwapakati kumasokonekera. Valve yoyang'ana yoyamba imatseka kuti muteteze kubwereranso kuchokera kudera lapakati kupita kulowera. Ngati valavu yachiwiri yowunika iwonanso kukakamizidwa kobwerera, imatseka kuti itseke kubwerera kuchokera kumbali yotulukira kupita kudera lapakati.

Kuyambitsa Vavu Yothandizira
Ambiri oletsa kubwerera kumbuyo ali ndi valve yothandizira yolumikizidwa kudera lapakati. Ngati ma valve onse a cheki akulephera kapena ngati kupanikizika m'dera lapakati kumadutsa mphamvu yolowera (kusonyeza chiopsezo chobwerera m'mbuyo), valavu yothandizira imatsegula kuti itulutse madzi oipitsidwa m'dera lapakati kupita kumlengalenga (kapena kayendedwe ka madzi). Izi zimalepheretsa madzi oipitsidwa kuti asabwererenso m'madzi oyera, kusunga umphumphu wa dongosolo loyamba.

Ntchito Yodzichitira
Njira yonseyi ndi yodziwikiratu, yosafuna kuchitapo kanthu pamanja. Chipangizocho chimayankha mwamphamvu kusintha kwa kuthamanga kwa madzi ndi kayendedwe ka kayendedwe ka madzi, kuonetsetsa kuti chitetezo chisasunthike pobwerera m'mbuyo pansi pazikhalidwe zosiyanasiyana zogwirira ntchito.

Ubwino wa Backflow Preventers

Backflow preventersZimagwira ntchito yofunika kwambiri poteteza zida zamadzimadzi, makamaka madzi akumwa, poletsa kuthamangitsidwa kwazinthu zoyipitsidwa kapena zosayenera. Ubwino wawo waukulu ndi:

1. **Kutetezedwa kwa Ubwino wa Madzi**

Ubwino wake waukulu ndikuletsa kuipitsidwa pakati pa madzi amchere ndi magwero osathira (monga madzi otayira m'mafakitale, madzi amthirira, kapena zimbudzi). Izi zimatsimikizira kuti madzi akumwa kapena madzi oyeretsera amakhalabe osadetsedwa, kuchepetsa kuopsa kwa thanzi lokhudzana ndi kumwa madzi oipitsidwa.

2. **Kutsata Malamulo**

M'madera ambiri, oletsa kubwerera m'mbuyo amalamulidwa ndi malamulo a mabomba ndi malamulo a zaumoyo (monga omwe amakhazikitsidwa ndi mabungwe monga EPA kapena akuluakulu amadzi am'deralo). Kuziyika kumathandiza kuti malo ndi machitidwe akwaniritse zofunikira zalamulo, kupewa chindapusa kapena kutsekedwa kwa ntchito.

3. **Kusafunikira ndi Kudalirika**

Ambirizoletsa kubwereraimakhala ndi ma valavu apawiri komanso ma valve othandizira, ndikupanga chitetezo chowonjezera. Ngati chigawo chimodzi chikulephera, ena amakhala ngati zosunga zobwezeretsera, kuchepetsa chiopsezo cha kubwereranso. Kapangidwe kameneka kamatsimikizira kugwira ntchito kosasinthasintha ngakhale pansi pa kusinthasintha kwa kupanikizika kapena kuyenda.

4. **Kusinthasintha Pakati pa Mapulogalamu **

Amatha kusintha machitidwe osiyanasiyana, kuphatikizapo nyumba, malonda, mafakitale, ndi ma municipalities. Kaya amagwiritsidwa ntchito pamakina opangira madzi, ulimi wothirira, kapena mizere ya mafakitale, olepheretsa kubwerera kumbuyo amalepheretsa kubwereranso mosasamala kanthu za mtundu wamadzimadzi (madzi, mankhwala, etc.) kapena kukula kwa dongosolo.

5. **Kuchepetsa Kuwonongeka kwa Zida **

Poyimitsa kuyenderera kwa reverse, olepheretsa kubwerera kumbuyo amateteza mapampu, ma boilers, zotenthetsera madzi, ndi zida zina zamakina kuti ziwonongeke chifukwa cha kupsinjika kapena nyundo yamadzi (kuthamanga kwadzidzidzi). Izi zimakulitsa nthawi ya moyo wa zida ndikuchepetsa ndalama zosamalira.

6. **Automatic Operation**

Backflow preventerskugwira ntchito popanda kulowererapo pamanja, kuyankha nthawi yomweyo kusintha kwamphamvu kapena kusintha kwamayendedwe. Izi zimatsimikizira chitetezo chosalekeza popanda kudalira kuyang'anira anthu, kuwapanga kukhala oyenera machitidwe osayendetsedwa kapena akutali.

7. **Kusunga Ndalama**

Ngakhale kuti ndalama zoyambira zilipo, zosungirako nthawi yayitali ndizofunika kwambiri. Amachepetsa ndalama zomwe zimawononga pakuyeretsa madzi, kukonza zida, zilango zowongolera, komanso chiwongolero chomwe chingachitike pazaumoyo wokhudzana ndi madzi oipitsidwa. Kwenikweni, zoletsa kubwerera m'mbuyo ndizofunikira kwambiri pakusunga umphumphu wadongosolo, thanzi la anthu, komanso magwiridwe antchito pamagwiritsidwe osiyanasiyana amadzimadzi.
