In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1-3, the present invention provides a technical solution: a fan induced draft control valve device comprises a cylinder 1, a bakelite support seat 2, a bakelite sliding block 3, a valve body air suction pipe 4, an air inlet 5 and a suction valve air source inlet 6; a suction valve air source inlet 6 and an air inlet 5 are formed in the bakelite support seat 2, a valve body air suction pipe 4 matched with the suction valve air source inlet 6 and the air inlet 5 is arranged on the bakelite sliding block 3, the valve body air suction pipe 4 is used for connecting a negative pressure station, and the bakelite sliding block 3 is in sliding connection with the bakelite support seat 2 under the action of the air cylinder 1; bakelite sliding block 3 slides and sets up on bakelite supporting seat 2, all has deflector 7 through the screw mounting on the lateral wall about bakelite supporting seat 2, is provided with guide way 8 on deflector 7, and bakelite sliding block 3 slides and sets up in guide way 8.
Further, the cross section of the guide plate 7 is of an L-shaped structure.
Further, the vertical portion of the guide plate 7 is fixed to the side wall of the bakelite support base 2 by screws, and a cavity between the bakelite support base 2 and the horizontal portion of the guide plate 7 is provided as a guide groove 8.
Further, the output end of the air cylinder 1 is connected with a connecting seat 10 through a bull eye bearing 9, and the connecting seat 10 is fixed on the bakelite sliding block 3.
Further, the cylinder 1 is horizontally fixed on the bakelite support seat 2 through the matching of the flange 11 and the bolt.
