您要查找的是不是:
- Close the shutoff valve upstream of the regulator. 關閉調節閥上游的關斷閥。
- Close shutoff valve No. 2 then No. 1. 關閉關閉閥2號,然后關閉關閉閥1號。
- Close shutoff valve No. 2 then shutoff valve No. 1. 關閉2號關閉閥,然后關閉1號關閉閥。
- Purpose: To test shutoff valve No. 2 for tightness. 目的:檢測2號關閉閥的密封性。
- Install a shutoff valve upstream of the regulator. 在調節閥的上游安裝關閉閥。
- Remove bypass hose from test cock No. 1, open shutoff valve No. 1. 從測試旋塞1號上拆卸旁路軟管,開啟1號關閉閥。
- The test cock is on the inlet side of the shutoff valve. 測試旋塞位于關閉閥的進口一側上。
- Install a shutoff valve in the cold water inlet line. 在冷水進水管處安裝一個關閉閥。
- Close shutoff valve No. 2 then shutoff valve No. 1 on the assembly. 關閉2號關閉閥,然后關閉總成上的1號關閉閥。
- No downstream shutoff valves are allowed. 不允許有下游關閉閥。
- FLIGHT CONTROLS HYDRAULIC SHUTOFF VALVES. 飛行操縱液壓關斷活門。
- Close shutoff valves No. 1 and No. 2. 關閉1號關閉閥和2號關閉閥。
- Close shutoff valve No. 2 then shut off valve No. 1 on test assembly. 關閉2號關閉閥,然后關閉測試總成上的1號閥門。
- Remove all test equipment and open No. 2 shutoff valve of the device. 拆卸所有檢測設備,開啟裝置上的2號關閉閥。
- There can be no shutoff valves downstream of an AVB. 在大氣真空斷路閥的下游不能有關斷閥。
- If the reading returns to +PSID, No. 2 shutoff valve is leaking excessively and must be replaced to test the valve. 如果讀數恢復到+PSID,則2號關閉閥泄漏過于嚴重,必須對其更換,以便進行閥門的檢測。
- Install a shutoff valve in the cold water inlet. Install a listed temperature-pressure relief valve in the remaining fitting. 在冷水進水管上安裝一個關斷閥。在剩下的螺紋接頭上安裝額定溫度/水壓的安全閥。
- Gate valves are the most commonly used shutoff valve in the industry today. 如今行業內,閘閥最常用作關閉閥,用于要求壓降最小,能夠雙向啟閉的應用場合。
- Slightly open shutoff valve No. 1 and allow water to fill the tube to the top then close No. 1 shutoff. 稍微開啟關閉閥1號,將水注入管子直到頂部為止,然后關閉1號關閉閥。
- NOTE: For Australia and New Zealand: Pipeline strainers should be installed between the upstream shutoff valve and the inlet of the backflow preventer. 注意:適用于澳大利亞和新西蘭:管路過濾器應該安裝在上游關閉閥和防回流閥進口之間。
