[0014] Furthermore, a diverter pipe 52 is provided on one side of the valve body 5 , and the diverter pipe 52 is provided to realize the diversion of the polymer.
[0015] Furthermore, the multiple groups of cone shapes of the shear end 43 array can reduce the resistance received by the fluid multiple times through the multiple groups of cone shapes, reduce the shear force multiple times, and further optimize the effect.
[0016] Furthermore, the valve body 5 is installed with an actuator 10 , and through the setting of the actuator 10 , the relevant parameters of the polymer in the valve body 5 can be collected in real time.
[0017] Example 1, when the pressure difference is 1.0MPa, the polymer concentration is 5000mg / L, the flow rate is 3m3 / h, 5m3 / h, 7m3 / h, the viscosity loss is 0.1%-1.0%.
