Embodiment
Below in conjunction with description of drawings and embodiment the utility model is done further to describe in detail.
Referring to Fig. 1 to Fig. 4, the board-like unloading valve of the pendulum of the utility model comprises valve body 1; Valve plate 2, the inwall of valve body 1 upper end is provided with seal ring 3, through lock pin bearing pin 4 valve plate 2 is installed on the madial wall of said valve body 1; The fixed plate 15 of valve plate 2 lower end surfaces is provided with skewed slot 8, and bearing pin 9 is installed in the skewed slot 8, and bearing pin 9 is connected with an end of piston rod 7; The other end of piston rod 7 passes valve body 1 and is connected with drive unit; The below of said seal ring 3 is provided with rubber seal 5, and the below of rubber seal 5 is provided with seal ring pressure ring 6, and corresponding rubber seal 5 is provided with protruding arc surface on the described valve plate 2.
The internal diameter of said seal ring pressure ring 6 is less than or equal to the internal diameter of rubber seal 5, and the internal diameter of rubber seal 5 is less than the internal diameter of seal ring 3.
The upper-end surface of said valve plate 2 is the sphere that raises up.
Said valve body 1 is a cylindrical shape, and a side of valve body 1 connects the transition casing 11 that is connected with rectangle.
Described transition casing 11 is provided with drive unit fixed base 13, on the drive unit fixed base 13 drive unit is installed.
Described drive unit is oil hydraulic cylinder 14 or cylinder.
On the inwall of valve body 1 upper end, be respectively arranged with seal ring 3 and seal ring pressure ring 6; Between seal ring 3 and seal ring pressure ring 6, accompany rubber seal 5; Seal ring 3 also can be annular boss, and seal ring pressure ring 6 mainly plays the support of rubber seal 5 and fixation.The internal diameter of seal ring pressure ring 6 is less than or equal to the internal diameter of rubber seal 5, and the internal diameter of rubber seal 5 is less than the internal diameter of seal ring 3, and the dust above can avoiding so directly drops on the rubber seal 5 and influences sealing effect.The lower end of seal ring pressure ring 6 is equipped with valve plate 2; One end of valve plate 2 is installed on valve body 1 inwall of seal ring pressure ring 6 lower ends through lock pin bearing pin 4; The upper-end surface of valve plate 2 is the arc surface that raises up; The fixed plate of the lower end surface of valve plate 2 is provided with skewed slot 8, and the bearing pin 9 that can in skewed slot 8, slide is installed in the skewed slot 8, and an end of piston rod 7 is connected with bearing pin 9.
The outside of valve body 1 is fixed with drive unit fixed base 13, and oil hydraulic cylinder or cylinder are installed on the drive unit fixed base 13, and the end of piston rod 7 reaches the outside of valve body 1 and is connected with oil hydraulic cylinder or cylinder, promotes piston rod 7 through oil hydraulic cylinder or cylinder level.In the time of need closing the valve plate 2 of unloading valve; Oil hydraulic cylinder or cylinder level promote piston rod 7; Piston rod 7 makes bearing pin 9 slide and promote valve plate 2 along skewed slot 8 and upwards rotates around lock pin bearing pin 4; The upper end face of valve plate 2 contacts and compresses with rubber seal 5 after valve plate 2 is horizontal, and unloading valve is closed.In the time of need closing the valve plate 2 of unloading valve, piston rod 7 retractions, piston rod 7 make bearing pin 9 slide and spur valve plate 2 along skewed slot 8 and rotate around lock pin bearing pin 4, and valve plate 2 is opened.Rubber seal 5 is that line contacts with the upper end arc-shaped surface of valve plate 2; Compare with the mode that seal ring employing face in traditional unloading valve contacts; This line contact sealing can make sealing part not have dust and particulate matter, not only helps sealing closely, and helps reducing wearing and tearing.
On the outer wall of valve body 1 and the lower end that is positioned at piston rod 7 be provided with transition casing 11; The intracavity inter-connection of transition casing 11 and valve body 1; The space of unloading under the dust when transition casing 11 can increase valve plate 2 and is in open mode can prevent that valve plate 2 from influencing owing to the space of unloading under the dust is less to unload ash when open mode.This is put board-like unloading valve and can singlely use, and also can use in pairs, if be separately installed with a unloading valve up and down; When unloading grey operation, open the unloading valve that is positioned at the top earlier, the unloading valve that be positioned at the below this moment is in closed condition; Dust unloads the back and gets in the cavity between two unloading valves, and when waiting dust to reach a certain amount of, the unloading valve of top is closed; The unloading valve of below is along with unlatching, and dust falls.Accomplish the unloading valve of the rear lower side and close, the unloading valve of top is opened, and repeats said process.
The upper end of unloading valve is equipped with push-pull valve 10, and push-pull valve 10 is in opening state when flat, closure just during the maintenance of the unloading valve below being positioned at only, and the plate on the push-pull valve 10 can move forward to realize closure when rotary handle crank.Offer viewing window 12 on the cylindrical shell of unloading valve below, can easily observe and unload grey situation, open viewing window 12 and can overhaul.
