Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Present embodiment discloses a kind of gate valve, as shown in Figure 1, 2, including valve body 1, offered in valve body 1 valve plate passage 2 with
And water channel 3 that is vertical with valve plate passage 2 and connecting, valve rod 4 is threaded in valve body 1, one end of valve rod 4 is located at outside valve body 1,
The other end is located in valve body 1.One end that valve rod 4 is located in valve plate passage 2 is rotatably connected to hinged block 5, and the both sides of hinged block 5 are consolidated
Surely there is rectangular connection sheet 6, the centre of two panels connection sheet 6 is provided with articulated shaft 7, axis and the both sides connection sheet 6 of articulated shaft 7
Perpendicular and articulated shaft 7 both ends are fixedly connected respectively with connection sheet 6.
As shown in Figure 2,3, hinged block 5 is connected with valve plate 8, and valve plate 8 includes two pieces of left valve plates 9 for being rendered as collar plate shape and the right side
