连接在气压调节器下游的控制装置可防止气压过大。
如果不满足要求的运行条件,则关闭气源。
对于所有气压控制系统,根据EN 746-2,都需要一个安全截止阀,在该系统中,气压调节器下游的控制装置不能抵抗供气压力。
Controls which are connected downstream of a gas pressure regulator are secured against excess gas pressure.
If the required operating conditions are not met, the gas supply is shut off.
A safety shut-off valve is required in accordance with EN 746-2 for all gas pressure control systems in which the controls downstream of the gas pressure regulator are not resistant to the supply pressure.
