<p>Disclosed is a water hammer discharge valve, comprising a valve body (1) and a sleeving tube (12) connected via a connecting seat (7), wherein a valve seat (2) and a valve clack (4) which are mutually matched are arranged in the valve body (1), the valve clack (4) is provided with a central shaft (4.1), a pressure adjusting system is arranged in the sleeving tube (12), a central hole (7.1) matched with the central shaft (4.1) of the valve clack (4) is arranged at the lower end of the connecting seat (7), an inner hole (7.2) is arranged at the upper end of the connecting seat (7), the central hole (7.1) is in communication with the inner hole (7.2), the central shaft (4.1) of the valve clack (4) passes through the central hole (7.1) of the connecting seat (7), a piston (9) is arranged between the central shaft (4.1) of the valve clack (4) and the pressure adjusting system, and the piston (9) is arranged in the inner hole (7.2) of the connecting seat (7) in a sealing mode; and the side of the connecting seat (7) is also in communication with an oil cup (16) via a connecting pipe (17), and a one-way throttle valve (15) is mounted on the connecting pipe (17). The present invention is simple in structure and reasonable in design, can be rapidly started for eliminating a water hammer, can slowly close at the same time, avoiding a secondary water hammer being produced due to a valve being closed too quickly, and thus having a high practical value.</p> |
