Fig. 3 is the front view of its valve seat;
Fig. 4 is the front view of its valve plate.
Embodiment
With reference to Fig. 1-4, this Flap valve comprises:
A valve seat 1, this valve seat 1 has a flat board 11, and valve port 12 is established at dull and stereotyped 11 middle parts, and the edge of valve port 12 extends to form installing ring 13 to a dull and stereotyped side on the flat board 11, some mounting holes 15 that distribute on dull and stereotyped 11, one side on dull and stereotyped 11 in a pair of axle bed 14,14 ' of being provided with of valve port 12;
A valve plate 2, this valve plate 2 places valve 12 places of described valve seat 1 and connects with the axle bed 14,14 ' of valve port while passing through axle 4,4 ', valve plate 2 another sides are provided for this valve plate is fixed on fixing device 24 on the valve seat 1, and valve plate 2 nearly center are provided for promoting the handle 25 that this valve plate rotates;
The installing ring 13 of valve seat 1 is vertical substantially with the flat board 11 of this valve seat.In the present embodiment, valve seat 1 is rectangular, is welded by four angle steel, and the another side that a side of four angle steel surrounds 11, four angle steel of flat board of described valve seat 1 surrounds the installing ring 13 of described valve seat 1; Valve plate 2 adopts channel-section steel 21 as main body, at two baffle plates 22,22 ' of channel-section steel 21 two ends welding, in baffle plate 22,22 ' upper end axis hole 23,23 ' is set respectively, is used for valve plate 2 is rotatably installed on the axle bed of valve seat 1.
The manufacturing of present embodiment Flap valve, transportation, easy for installation, concrete grammar is as follows:
Manufacture process: 1. at first valve seat 1 and valve plate 2 are welded on the platform of factory and finish; 2. on large-scale grinding machine, the junction plane of valve seat 1 with valve plate 2 polished; 3. load onto O-ring seal 3; 4. with axle 4,4 ' valve sets installed; 5. valve plate 2 is locked on the valve seat 1 by fixing device 24 and screw rod 16 with nut, valve is just made and is finished.
