Fig. 2 is upper shell plan structure schematic diagram of the present utility model;
Fig. 3 is support arm plan structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
With reference to Fig. 1-3, rotating material valve described in the utility model, comprise upper shell 1 and lower shell body 9, described upper shell 1 is provided with cylinder supports plate 21, cylinder 19, seal ring 12, rotating shaft 13, connecting rod 17, contiguous block 18 and support arm 11, connecting rod 17 is connected with cylinder 19 by contiguous block 18, described cylinder 19 is connected with cylinder supports plate 21, the two ends of described rotating shaft 13 are connected with connecting rod 17 and support arm 11 respectively, the two ends of described rotating shaft 13 are provided with gland 16, the inside of described gland 16 is provided with seal ring 14, one end of described support arm 11 is provided with valve plate 4, described valve plate 4 seals with seal ring 12 forming surface, the lower end of described valve plate 4 is provided with blind hole 15, described lower shell body 9 is fixedly connected with upper shell 1 by bolt 2, and locked by nut 3, it is characterized in that: one end of described support arm 11 connects valve plate 4, the bottom of described valve plate 4 is provided with two support blocks 5, with rotating shaft 13 on the same axis.
One end that described support arm 11 connects valve plate 4 is provided with two monaurals 22, and the surrounding and the valve plate 4 that are distributed in the shaft shoulder fit tightly.The setting of monaural 22 increases the area of contact with valve plate 4, thus ensures that valve plate 4 is more steady.
Described support arm 11 is provided with spring strut 10, is provided with Compress Spring 6 in described spring strut 10, and the top of described Compress Spring 6 contacts with the blind hole 15 on valve plate 4, and bottom is connected with spring seat 7.Contact extrusion spring seat 7 by adjusting screw 8 thus pressure adjustment is carried out to Compress Spring 6.
