Wherein, two sets of circulation passageway 2 have partial area for parallel arrangement, and the both ends interconnect of two sets of circulation passageway 2 is the square of mouth. The feed pipe 3 and the discharge pipe 4 are respectively arranged at two ends of the flow channel 2, wherein the functions of the feed pipe 3 and the discharge pipe 4 can be exchanged, and the installation design is carried out according to requirements. In addition, in the present application, two sets of diaphragm valve elements 5 are respectively installed in the mutually parallel regions of the two sets of flow channels 2, and the two diaphragm valve elements 5 may be coaxially disposed. It should be noted that, two sets of flow channels 2 are provided with flow through cavities 21, and two sets of diaphragm valve cores 5 are respectively installed in the corresponding flow through cavities 21. The valve body 1 can be provided with a valve cover 13 in the area corresponding to the overflowing cavity 21, wherein the valve cover 13 fastens the edge of the diaphragm valve core 5 on the edge of the overflowing cavity 21 close to one side of the valve cover 13, and is fastened by a screw, and a gap exists between the middle part of the diaphragm valve core 5 and the bottom of the overflowing cavity 21, so that the communication of the circulating channel 2 can be realized. When the middle of the diaphragm valve element 5 completely engages the bottom of the flow-through chamber 21, a closure of the flow channel 2 is achieved.

The pneumatic diaphragm valve of the utility model is provided with two sets of circulation channels 2 in the valve body 1, the two sets of circulation channels 2 are utilized to reduce the water hammer problem in the opening and closing process of the traditional single-group channel, and simultaneously, the pressure in plugging is also reduced; corresponding diaphragm valve cores 5 are arranged in each flow channel 2 respectively, and the same pneumatic mechanism 6 is adopted to drive the two sets of diaphragm valve cores 5 to plug the two flow channels 2, so that efficient plugging is realized, the reaction force of the pneumatic mechanism 6 is reduced, and further the abrasion is reduced.
