Terrestrial heat recharge system and impulsive force valve

The invention is suitable for the technical field of terrestrial heat utilization, and provides a terrestrial heat recharge system and an impulsive force valve. The terrestrial heat recharge system comprises a recharge well, a lifting pump, a filtering and emptying unit, a conveying pipeline and an impulsive force valve. According to the terrestrial heat recharge system provided by the invention, the impulsive force valve is arranged in the recharge water flow direction and located between the lifting pump and the conveying pipeline, and during lifting operation, the impulsive force valve communicates with the lifting pump and the conveying pipeline; during recharge operation, the impulsive force valve cuts off communication between the lifting pump and the conveying pipeline, and recharge water in the conveying pipeline is discharged into the recharge well, so that the situation that the recharge water flows into the lifting pump in the recharge process is reduced, damage to the lifting pump is reduced, the
