如果泄压口正常，那么，不接工件，用高压截止阀截断压力，看试验机本身能否保住压力。
If the discharge pressure is normal, so, don't answer the artifacts, cutting with high pressure cut-off valve pressure, see if we can keep pressure testing machine itself.
防护区应设置泄压口，防护区设置的泄压口，宜设在外墙上，安装高度应为室内高度的三分之二处。
Set up the pressure relief device in the protection area, it shall be placed over 2/3 of the net height in the protection area, shall be set up in the outer wall.
