In order to increase the valvebarrel strength and service life, the method of hole hydraulic self-reinforced is used.
为了增加泵头体的强度和使用寿命，采用内孔液压自增强法对内腔进行预应力处理。

The higher flow capacity and reduced turbulence in the valve allow the barrel filling operation on the scale to be accomplished faster and with less splashing and waste.
流动性更好了，也降低了阀门内流体的紊乱，因此灌桶过程更快，溅出浪费也更少。

The barrel, plunger and standing valve of the pump were designed, improving the barrel's force conditions and reinforcing the screw thread's sealing performance and tensile strength.
