          在水电厂中，装设在水轮机蜗壳前的阀门称为主阀。

 　　水力控制阀主阀是一种利用水自润式阀体，减压阀无须另加机油润滑，如遇主阀内零部件损坏时，请按下列指示进行拆卸。（注：内阀内一般消耗损伤品为膜片和○型圈，其它内部零件损伤甚少） 1.先将主阀前后端闸阀关闭。 2.将主阀盖上的配管接头螺丝松开,调节阀释放阀内压力。 3.将所有螺丝取下， 呼吸阀包括控制管路中的必要铜管的螺帽。 4.取阀盖和弹簧。 5.将轴芯、膜片、活塞等取下，切勿损伤膜片。 6.将以上各项东西取出后，检查膜片及○型圈是否损坏；如无损坏请勿再分自行争其内部零件。 7.如发现膜片或○型圈有损坏，锻钢阀门请将轴芯上的螺帽松脱，逐浙分解出膜片或型圈，取出后重新换上新的膜片或○型圈。 8.详细检视主阀内部阀座、轴芯等是否有损坏，针型阀若有其它杂物在主阀内部将其清理出。 9.依反向是顺序将更换后的零部件组合装好主阀，注意阀门不能有卡阻现象。 10.请参考安装操作注意事项重新用。

            In the hydropower plant, the installation of the valve in the turbine spiral case is called before the main valve. Hydraulic control valve is used Fazhu self-lubricating body of water without additional lubrication oil, the main valve Reducing Valvesparts in case of damage, please follow the instructions to demolition. (Note: the general consumption of injury within the valve products for the diaphragm and ○-ring, very little damage other internal parts) 1. First valve before and after the Balance Valvesend of the main valve closed. 2. The main valve fittings with screw lid release, pressure release valve. 3. Will remove all the screws, including Safety valves the control of the necessary copper piping in the nuts. 4. Take valve cover and spring. 5. The shaft, diaphragm, piston, etc. removed, do not damage membranes. 6. After removing the above stuff, check diaphragm and ○-ring is damaged; Do not be divided without damage to the internal parts on their own struggle. 7. If found ○ diaphragm or ring is damaged, please loose nut on the shaft, it gradually decomposed patch or ring,API Cast Steel Valves remove and replace the new patch or re-○-ring. 8. Details View inside the main valvePlug Valves seat, shaft, etc. for damage, if other debris within the main valve to clean out. 9. By the reverse is the order of replacement parts to install a good combination of the main valve, the valve can not have jamming attention to the phenomenon. 10. Please refer to installation to attention again to use.
