Audo Look6.0 downloadWhen the drive pressure of set machine pump, accurate method is to make drive presses 1-1.5kg/cm2 of back pressure of force prep above (15-20psig) . This is correct below most circumstance. But discharge an amount to achieve the requirement of pump sometimes, need sets drive pressure a few more tallishly. When drive pressure is high, adverse one side is easy wear away to entering gas a powerful person to cause. If drive presses force prep above to ask to be worth, can serious to entering gas a powerful person to cause wear away and must change ahead of schedule a powerful person that take energy of life.
Below this kind of circumstance, the proposal uses pressure-relief valve or pressure-relief valve stands. Pressure-relief valve can allow to keep drive pressure already calm pressure is set in what can satisfy pumpage, also can protect a powerful person that take energy of life not to suffer at the same time wear away. Additional, it is when applied space is more cramped, the proposal uses the pressure-relief valve station that carries dry pipe. In process of pump pump water, dry pipe provided buffer for pump thereby for steam for pump. This buffer makes the movement of whole apparatus downy, reduce pair of pressure-relief valve wear away.
