安全阀是对于热风炉来讲,是非常的重要,目的就是能够确保热风炉安全的运转,在热风炉或着是管道中的介质压力升高的话,如果超过了规定值的时候就会自动开启,对于热风炉实行安全停机。安全阀如此的重要,对于它旳安装,又有什么安装的注意事项呢,小编根据多年从业的经验,总结几点如下。
Safety valve is very important for hot-blast stove. The purpose is to ensure the safe operation of hot-blast stove. If the pressure of medium in hot-blast stove or pipeline rises, it will automatically open if it exceeds the prescribed value, and the stove will be shut down safely. Safety valve is so important, for its installation, what are the installation considerations? Based on years of experience, the editor summarizes several points as follows. 一、安全阀旳安装
Installation of Safety Valves

1.安全阀需要使在热风炉水压试验完成之后进行安装,需要在初次升火的时候对于安全阀工作压力进行调整。
1. Safety valve needs to be installed after the hot stove water pressure test is completed, and the working pressure of the safety valve needs to be adjusted during the initial fire.

2.依照国家劳动总局“热风炉安全技术监察规程”143条表7-2规定的压力进行调整。
2. The pressure shall be adjusted in accordance with Table 7-2 of Article 143 of the Regulations for Safety and Technical Supervision of Hot Blast Furnace of the State Administration of Labor.


二、安全阀的调整
II. Adjustment of Safety Valves

1.拆去开口销,除去顶盖,拧松六角锁紧螺母,然后拧动调节螺杆,使弹簧放松或拧紧,来达到安全阀要求的排汽压力。
1. Remove the opening pin, remove the top cover, loosen the hexagonal locking nut, and then twist the adjusting screw to relax or tighten the spring to meet the exhaust pressure required by the safety valve.

2.调整后拧紧锁紧螺母,再将其余零件装妥。当安全阀达到规定的整定压力后应进行铅封,除非安全阀进行校验时,其它任何时候不允许私自拆卸铅封。
2. Tighten the locking nut after adjustment, and then install the rest of the parts. Lead seal shall be applied when the relief valve reaches the required setting pressure. Unless the relief valve is checked, it is not allowed to disassemble the lead seal privately at any other time.

3.首先,在调整安全阀时,锅筒内之水位应较平常水位略低,并预备在安全阀开启后能随时进水。
3. First of all, when adjusting the safety valve, the water level in the drum should be slightly lower than the normal water level, and ready to enter water at any time after the safety valve is opened.

4.还有就是 ,一定不可以敲击安全阀上面的任何部分,开启安全阀只可以使用阀上的控制杆。
4. Also, you must not knock on any part of the safety valve. To open the safety valve, you can only use the control rod on the valve.

5.然后,在安全阀没有调整之前热风炉一定要禁止运用。
5. Then, the hot stove must be prohibited before the safety valve is adjusted.
