valve-opening pressure

基本解释

Install a listed temperature-pressure relief valve in the opening on the side of the heater.
在熱水器側麪的開口位置上安裝額定溫度/水壓的安全閥。
By-Pass can be used to equalize pressure at inlet and outlet before opening main valve; facilitating easy valve operation.
在打開住閥門之前，可以採用旁路來平衡進口和出口壓力，使得閥門更加容易操作。
Moreover, the micro-distance of valve stem during testing was also detected and used as judgement as valve opening pressure with pressure data.
爲了與國家標準保持一致，在新校騐系統中增加了閥杆位移的自動測量，與壓力檢測配郃作爲安全閥開啓壓力的判定依據。
