Slight resistance Non-return Backflow Preventer (Flanged Type) TWS-DFQ4TX-10/16Q-D - is a kind of water control combination device developed by our company, mainly used for water supply from urban unit to the general sewage unit strictly limit the pipeline pressure so that the water flow can only be one-way. Ntchito yake ndikupewa kusanja kwapakatikati kapena chinthu chilichonse Sifeon abwerera, kuti apewe kuipitsa.

Makhalidwe:

1. Ndi yaying'ono komanso yayifupi; kukana pang'ono; Kupulumutsa Madzi (Palibe chotupa chonyansa panjira yamadzi abwinobwino); safe (in abnormal loss of pressure in the upstream pressure water supply system, the drain valve can be open timely, emptying, and the middle cavity of backflow preventer always takes precedence over the upstream in air partition); Kuzindikira pa intaneti ndi kukonzanso kwa etc. Pamagulu wamba pakuyenda kwachuma, kuwonongeka kwa madzi kwazinthu zomwe zimapanga zida 1.8 ~ ma 2.

3. Mapangidwe olondola a Valani valavu, kupsinjika kumatha kusintha phindu lofufumitsa lodula dongosolo lamadzi, kuti mupewe kusinthasintha kwa dongosolo. Pa-onyamuka bwino komanso modalirika, palibe kutaya kwamadzi konyansa.

6. Mapangidwe a anthu akhoza kukhala mayeso pa intaneti ndi kukonza.

Mapulogalamu:

Itha kugwiritsidwa ntchito poipitsidwa ndi kuipitsa, chifukwa chowopseza poizoni, amagwiritsidwanso ntchito ngati sangathe kubwezeretsedwa ndi mpweya wabwino;
Itha kugwiritsidwa ntchito poyambitsa chitoliro cha nthambi m'malo owonongeka ndikuyenda kosalekeza, osagwiritsidwa ntchito popewa kuleka
kuwonongeka kwa poizoni.
