Negative pressure eliminating device in recharge water well
The invention relates to a negative pressure eliminating device in a recharge well, which is structurally characterized in that a floater is arranged in a recharge pipe inserted into the recharge well, a conical upper cover body is suspended at the lower end of the floater, and the conical upper cover body covers a pipe orifice blocking body and is connected with the pipe orifice blocking body through a telescopic connecting piece; a necking sealing and blocking edge used for preventing the pipe opening sealing and blocking body from being disengaged is arranged at the lower end opening of the recharge pipe. A plurality of oblique impact drainage channels are formed in the pipe orifice blocking body, the upper end openings of the impact drainage channels are formed in the top surface of the pipe orifice blocking body, and the lower end openings of the impact drainage channels are formed in the positions, capable of being blocked by necking-down blocking edges on the recharge pipe, of the pipe orifice blocking body; a vertical impurity discharging channel is formed in the middle of the pipe opening blocking body, and the lower end of the impurity discharging channel is communicated with the impact drainage channel through an inclined communicating pipe. The change amplitude of the water level in the pipe can be controlled within a certain range, the recharge pipe from the lower end opening to the wellhead section is filled with water, and therefore separation of gaseous substances contained in recharge water is correspondingly reduced.
本发明涉及一种回灌水井内负压消除装置，其结构是在插入回灌井的回灌管内设置有浮子，所述浮子的下端悬吊有锥形上盖体，锥形上盖体遮盖在管口封挡体上，并通过伸缩连接件与管口封挡体相接，在回灌管的下端口处设置有用于防止管口封挡体脱出的缩口封挡边；在所述管口封挡体中开有若干斜向冲击排水通道，所述冲击排水通道的上端口开在管口封挡体的顶面，所述冲击排水通道的下端口开在管口封挡体的能由回灌管上的缩口封挡边封挡住的位置处；在所述管口封挡体的中部开有直立的排杂通道，排杂通道的下端通过斜向连通管与冲击排水通道相连通。本发明可将管内水位的变化幅度控制在一定范围之内，使回灌管自下端口至井口段的回灌管内充满水，从而相应减少回灌水中所含的气态物质的析出。
