| Zusammenfassung: | The utility model discloses a geo-membrane downward air-exhausting pressure-reducing valve which is characterized by comprising a stainless steel hard frame (1). Two sides of the stainless steel hard frame (1) are fixed with a geo-membrane (9) through a thread (2) and a nut (3). A hollow upper channel and a hollow lower channel are arranged in the stainless steel hard frame (1). The upper portion of the stainless steel hard frame (1) is provided with an air outlet hole (4). The bottom of the stainless steel hard frame (1) is provided with an air inlet hole (6). The front of the air outlet hole (4) and the front of the air inlet hole (6) are respectively and sequentially provided with a heart-shaped valve (5), a rigid filtering membrane (7) and a rigid baffle (8). The geo-membrane downward air-exhausting pressure-reducing valve can improve collection of membrane lower air, prevents external water flow and soil from entering and causing block, can effectively exhaust air as a whole, and prevents the geo-membran |
