Detailed description of the invention
Below in conjunction with embodiment, this utility model is further described, but protection domain of the present utility model is not limited solely to embodiment.
One manually can enclosed storm valve, there is valve body 1, valve rod 13, valve gap 11, there is in valve body 1 valve seat 2, water stream channel 9 and the valve pocket 10 being made up of valve body 1 and valve gap 11, valve seat 2 is additionally provided with locating shaft 7, locating shaft 7 is physically located in valve pocket 10.Being provided with the arm of force 3 and lever 4 that are mutually connected to each other in valve body 1, shown in Fig. 3, one end of lever 4 is hinged with locating shaft 7, and lever 4 can rotate centered by locating shaft 7.
Shown in Fig. 4, the arm of force 3 being provided with sealing gasket 6, the side of sealing gasket 6 is provided with pressing plate 15, equipped with bolt assembly on pressing plate 15, makes described pressing plate 15 be pressed on the arm of force 3 by sealing gasket 6 by bolt assembly.Sealing gasket 6 is located close to the position of water stream channel 9, and lever 4 is located close to the position of valve pocket 10, and lever 4 is provided with balancing weight 5, and balancing weight 5 is arranged on lever 4 by bolt 8.The upside of valve pocket 10 is provided with sleeve pipe 12, and the lower end of valve rod 13 is placed in valve pocket 10 and is against on lever 4.Valve rod 13 upper end is provided with handle 14, and turning handle 14 can move up and down by band ovable valve stem 13.When not having current in water stream channel 9, relying on the gravity of balancing weight 5 and the downward active force of valve rod 13 can make to be close to sealing between sealing gasket 6 and valve seat 2, make water stream channel 9 closed center, current up can not reflux from little.When draining, turning handle 14 makes to move on valve rod 13, and sewage, from the top of water stream channel 9 toward dirty, relies on the impulsive force of water, and sealing gasket 6 and valve seat 2 depart from, and the arm of force 3 and lever 4 all rotate counterclockwise；After sewage discharge, relying on the gravity of balancing weight 5, the arm of force 3 and lever 4 rotate clockwise, and turning handle makes valve rod 13 move down, and valve rod 13 lower end abuts with lever compact, make to be close to sealing between sealing gasket 6 and valve seat 2.
