求翻译：将组合阀手轮旋转到底即全关，打开稳压阀盖，精心调节调压螺塞进出距离。当压力表指示达到你所需要求的（0.2—0.8MPa）后，检查稳压阀是否进入工作状态。如所调压力为0.4MPa，当进口压力升高后，稳压阀是否在0.4MPa打开降压，并保持进口压力不断续升高。当进口压力下降到0.4MPa以下，稳压阀是否关闭并且无泄漏。是什么意思？

The combination valve hand wheel rotation in the end that is, fully closed, open the regulator valve cover, and carefully adjust the regulator plug out of the distance. When the pressure gauge you need to ask (0.2-0.8mpa), check whether the regulator valve into the working state. The adjusted pressu

The combination valve handwheel that rotate throughout the gateway to open voltage regulator valve cover, carefully adjust pressure plug access distance. The pressure gauge indicates to you the necessary requirements of the (0.2 - 0.8 ) MPa, check for voltage regulator valve is in working condition.

The combination valve handwheel revolving namely entire pass, turns on the constant voltage valve cover, adjusts the accent to press the thread plug turnover distance carefully.After the pressure gauge instructed achieved you need to ask (0.2-0.8MPa), inspection constant voltage valve whether thrust

The combination valve handwheel rotation that is full off, open the regulator valve cover, carefully adjust the regulator screw in and out of the distance. When the pressure gauge indicates that needed to achieve your requirements (0.2-0.8MPa), check whether the regulator valve into a working state.
