怎樣安裝1噸燃氣鍋爐的壓力表
How to install 1 ton gas boiler pressure gauge
1、每臺1噸燃氣鍋爐必須裝有與鍋筒空間直接相連的壓力表。在給水調節閥前、可分式省煤器出口、過熱器出口、過熱器出口與主汽閥之間，再熱氣進出口、都應裝設壓力表。
Each steam boiler must have a pressure gauge connected directly to the drum space. In front of the feed water regulating valve, the outlet of the coal feeder, the outlet of the superheater, the outlet of the superheater and the main steam valve, the pressure gauge should be installed in the heat and the import and export.
2、而在每臺熱水鍋爐的進水管和出水管閥入口，都應裝一個壓力表。循環水泵的進水管和出水管上也應裝壓力表。
A pressure gauge should be installed in the inlet and outlet of each hot water boiler. The inlet pipe and outlet pipe of circulating pump should also be filled with pressure gauge.
3、壓力表的安裝位置應設置在便于觀察沖洗處，應避免受到輻射熱、凍結或振動等不利因素影響；表盤可向前傾斜15度。
The location of the pressure gauge should be set up to facilitate the observation and flushing and should avoid the adverse factors such as radiant heat, freezing or vibration. The dial can be tilted 15 degrees forward.
在壓力表的連接管外應該裝有存水彎管，使高溫蒸汽在存水彎管內凝結成水，防止高溫蒸汽直接進入彈簧管；同時壓力表應盡可能地裝在遠離高溫蒸汽管道或易受高溫輻射的地方；壓力表的彈簧管，由無縫銅管制成，它的工作條件應該保持在80度以下，如果彈簧管內長期直接受高溫蒸汽的作用，或壓力表裝在靠近高溫的地方，將會使壓力表的指示值產生誤差，影響壓力表的準確性和使用壽命，而且還可能使表內傳動機構損壞，因此，在壓力表下的連接管外應該裝有存水彎管；存水彎管的內徑，用銅管時不應小于6毫米，用鋼管時不應小于10毫米。在存水彎管的下部，最好裝有防水旋塞，以便停爐后放掉管內的積水。
The pipe should be installed in the connection tube of the pressure gauge, and the hot steam condenses into water in the pipe, preventing the hot steam from entering the spring tube directly. At the same time, the pressure gauge should be placed as far away from the high temperature steam pipeline or as susceptible to high temperature radiation. Pressure gauge of the spring pipe, made from seamless copper tube, its working conditions should be kept below 80 degrees, if the spring tube directly affected by the effect of high temperature steam for a long time, or in a place near the high temperature pressure gauges, will make the pressure gauge indicating value error, affect the accuracy of the pressure gauge and service life, but also can make table drive gear is damaged, therefore, under the pressure gauge of connecting pipe should be equipped with trap tube; The inner diameter of the pipe should not be less than 6mm in copper pipe and should not be less than 10mm in steel pipe. In the lower part of the depositing bend, it is best to have a waterproof cocks to remove the water from the pipe after the stove.
壓力表和緩沖彎管之間應裝有三通旋塞，它有兩個作用：一是沖洗存水彎管；二是裝置經過校驗的壓力表，以便核對工作壓力表的準確度。更換和校驗壓力表。
There should be a three-way cock between the pressure gauge and the cushioned pipe, and it has two functions: one is to flush the trap. The device is calibrated to check the accuracy of the work pressure gauge. Replace and check pressure gauge.
