DN50-DN400 Slight Resistance Non-return Flanged Backflow Preventer Has CE Certification made in China

Lanyuth:

Gwok ma nok Non-return Backflow Preventer (Flanged Type) TWS-DFQ4TX-10/16Q-D - utiye kit jam tic moko ma juyubu ku kampuni mwa, ma pol kare jutiyo kudu pi kelo pii kud i adhura ni kabedo mi pii ma rac ma juku pii ma mol kud i paip kara pii ubed yo acel kende. Tic pare utiye mi juku dwoko pa pipeline medium nyo kit moko ci pa siphon flow back, pi jwigo backflow pollution.

Kura kit:

1. Etiye piny ma nyap man ma nyap; kwero ma nok; gwoko pii (pe ku lembe ma rac ma nyayu pii i pii ma mol); ber (i rweny pa pii ma rwinyo i rwom ma malu, valve mi pii copo bedo ma oyabere i kare ma mitire, ma wok, man kabedo ma ikin pa backflow preventer kare ku kare bedo ma pire tek uloyu i rwom ma malu i poko pa yamo); nwangu man gwoko piny iwi yamu man mukende mapol. I thenge mi tic maber, peko pa pii ikum piny ma juyubu ubedo 1.8~ 2.5 m.

2. Two levels check valve' s wide valve cavity flow design is of flow small flow resistance, rapidly on-off seals of check valve, ma copo juku ret pa valve man pipe ku rwom ma malu mi back pressure, ku mute function, ma medo kwo pa valve.

3. Yub maber pa drain valve, drain pressure copo loko pressure fluctuation value pa cut off water supply system, mi gwoko pressure fluctuations pa system. On-off maber man ma gen, pii ma mol marac ope.

4. Kit ma juyubu kudo diaphragm madit miyo gen pa piny ma pire tek ubedo ber uloyu pa backlow preventer mukende, maber man gen pa on-off pi drain valve.

5. Kit ma juyubu ko pii ma dit man yore mi loko pii, pii ma pii pii man pii ma mol i valve cavity epe ku peko mi pii, juku yore mi dok piny man siphon flow reversals timere.

6. Yub ma dhanu timo copo bedu pima man gwoko iwi yamu.

Tic:

Ecopu tiyu kudu i pollution ma rac man pollution pa lero, pi pollution ma rac, jutiyo kudu de ka ecopu juku ngo dwoko cen pa yamo;
Ecopu bedu ni tiyo kudu pi kelo peko i pollution man pressure flow ma mediri, man jutiyo kudu ngo pi juku backlow pa
pollution ma rac.
