| description | The invention discloses an oil-submerged pump well washing valve and a well washing method, and relates to the technical field of oil-submerged pump well washing. The oil-submerged pump well washing valve comprises an oil pumping pipeline, wherein an oil way is formed in the oil pumping pipeline, a one-way valve is arranged in the oil pumping pipeline, the one-way valve divides the oil way into an upper oil way and a lower oil way, oil liquid flows from the lower oil way to the upper oil way in a one-way mode, the one-way valve is arranged in the oil pumping pipeline in a sliding mode, an elastic reset device which enables the one-way valve to slide upwards to a reset position is connected to the lower portion of the one-way valve, and a first through hole which communicates with the upper oil way is formed in the side wall of the oil pumping pipeline. When the one-way valve slides to the reset position, the one-way valve cuts off the first through hole and the upper oil way, when the one-way valve is subject |
