Why do water flow indic¶π‍©ators often alarm?

Time: 2018-10-11 17:38:20 Clic♣©✘k: 815times

Dear, in view of the situation you said, Xiao Bi≠δ§an believes that the water supply sid ×e pressure should rise, directly from the w&σ$‍ater supply side wat←ε​≈er pressure fluctuations, and theφ  wet alarm valve is essenti←£‌αally a check valve, ¥≠‌∑only water is allowed. F×‌™↓low in one direction. When the system side is atλ× a certain low pressure, the wet alarm valv€✘e is in the closed state, then→∏ the water pressure on the water s↑≤upply side rises, and the wet alarm valve open∏φ§s, causing a false ala‌≠φ♦rm. The method is: using a steady↑€♣-state pump to stabilize the vo‍∏±πltage, if the steady-state<₽ pump fills the level slowly, ©δ♥<the valve flap is always opened at a small angle'φα to replenish the pipe netwo✔₹≈rk, that is, no "false positives" will$✘‍γ occur. Therefore, it is recommended that you pay ↕♦ attention to the wat©₩er pressure not too high wheββ¶ n you use it in the future!
