Positive impulse generator of water injection well low discharge

The utility model provides a positive impulse generator of water injection well low discharge, including the body, still include ball valve, pulse valve, the body is inside offers two axial passage, is an axial passage and the 2nd axial passage respectively, the ball valve is installed in an axial passage, the pulse valve is installed in the 2nd axial passage. This internal ball valve drive mechanism that still installs, ball valve power input is connected to ball valve drive mechanism power take off end. Ball valve drive mechanism is the motor, and the power shaft output of motor passes through the valve shaft input of umbrella gear connection ball valve. The utility model discloses realize pressure pulse signal transmission to well head, the ball valve is only opened and is closed two states, and control mode is simple, during normal water injection, the path positive impulse generator normally open, and ball valve opening and closing torque is little. 本实用新型提供种注水井小流量正脉冲发生器，包括本体，还包括球阀、脉冲阀，所述本体内部开设两个轴向通道，分别为第
