- All pressure instruments shall have a vent valve to provide the capability of depressurizing the sensing line after the block valve is closed. 所有壓力儀表應配備一個(gè)排氣閥，以便在截止閥關(guān)閉后能夠使導壓管泄壓。
- A pilot-operated vent valve for pressure relief uses tank pressure, not weights or a spring, to keep the vent valve seat closed. 先導式通氣閥泄壓時(shí)利用儲罐壓力，而不是重力或彈簧外力，來(lái)保持通氣閥閥座關(guān)閉。
- For modulating action, the main vent valve opens gradually with increasing pressure and achieves rated relieving capacity at relieving pressure. 對于調制式先導器，主閥門(mén)將隨壓力增加而逐漸打開(kāi)，在泄放壓力時(shí)達到額定排放量。
- Unlike in a direct-acting vent valve, the force holding the seat closed in a pilot vent valve increases with increasing pressure. 不同于直動(dòng)式通氣閥，先導式通氣閥保持閥座關(guān)閉的作用力隨壓力增加而增加。
