怎样安装1吨燃气锅炉的压力表
How to install 1 ton gas boiler pressure gauge
1、每台1吨燃气锅炉必须装有与锅筒空间直接相连的压力表。在给水调节阀前、可分式省煤器出口、过热器出口、过热器出口与主汽阀之间,再热气进出口、都应装设压力表。
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、而在每台热水锅炉的进水管和出水管阀入口,都应装一个压力表。循环水泵的进水管和出水管上也应装压力表。
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、压力表的安装位置应设置在便于观察冲洗处,应避免受到辐射热、冻结或振动等不利因素影响;表盘可向前倾斜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.
在压力表的连接管外应该装有存水弯管,使高温蒸汽在存水弯管内凝结成水,防止高温蒸汽直接进入弹簧管;同时压力表应尽可能地装在远离高温蒸汽管道或易受高温辐射的地方;压力表的弹簧管,由无缝铜管制成,它的工作条件应该保持在80度以下,如果弹簧管内长期直接受高温蒸汽的作用,或压力表装在靠近高温的地方,将会使压力表的指示值产生误差,影响压力表的准确性和使用寿命,而且还可能使表内传动机构损坏,因此,在压力表下的连接管外应该装有存水弯管;存水弯管的内径,用铜管时不应小于6毫米,用钢管时不应小于10毫米。在存水弯管的下部,最好装有防水旋塞,以便停炉后放掉管内的积水。
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.
压力表和缓冲弯管之间应装有三通旋塞,它有两个作用:一是冲洗存水弯管;二是装置经过校验的压力表,以便核对工作压力表的准确度。更换和校验压力表。

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.
