Abstract
The invention discloses a pulse valve used for oil pipe blockage removing. The pulse valve comprises a valve body, a resonant pulse pipe, a periodic flow guide plate, a pulse rotating sheet, an upper fixing hole plate, a flow guide blade, a cooperation cylinder and a lower fixing hole plate, wherein the resonant pulse pipe, the periodic flow guide plate, the pulse rotating sheet, the upper fixing hole plate, the flow guide blade, the cooperation cylinder and the lower fixing hole plate are arranged in the valve body. The periodic flow guide plate is fixed to the middle of the valve body, the resonant pulse pipe is arranged on the periodic flow guide plate, and a gap exists between the resonant pulse pipe and the periodic flow guide plate. Crude oil flows into the valve from the lower end of the pulse valve used for oil pipe blockage removing, flows through the lower fixing hole plate, enters the flow guide blade, pushes the flow guide blade to rotate and then drives the pulse rotating sheet to rotate. Meanwhile, the crude oil flows through the cooperation cylinder, the flow guide blade and the lower fixing hole plate to reach the periodic flow guide plate. The crude oil generates periodic pressure changes at the periodic flow guide plate and then flows into the resonant pulse pipe. The periodic vibration of the crude oil is amplified through the resonant pulse pipe and then transmitted to a stratum and an oil pipe, and the function of removing blockage of a channel from an oil reservoir to a shaft is achieved.
