Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The utility model provides a novel rotatory unloading valve, includes motor 1, speed reducer 2, valve case 3, valve shaft 4 and fixed mounting multi-disc valve block 5 on valve shaft 4, valve shaft 4 and valve block 5 arrange valve case 3 in, 3 inner walls of valve case are located and use valve shaft 4 as the virtual face of cylinder in axle center, the upper end of valve case 3 is feed inlet 6, the lower extreme is discharge gate 7, motor 1 drive speed reducer 2 rotate, speed reducer 2 passes through the chain and drives the rotation of valve shaft 4. The above technical features existing in the prior art are not described in detail herein.

The utility model discloses an innovation point lies in: valve block 5 be extending structure, including fixed valve block 51 and movable valve block 52 two parts, fixed valve block 51 one end is installed on valve shaft 4, and the recess 9 is opened to the other end, movable valve block 52 activity cartridge is in recess 9 in, and then valve block 5 is scalable, has avoided the condition of card material to take place, avoids valve block 5's mechanical damage, more be favorable to promoting work efficiency. The movable valve plate 52 and the fixed valve plate 51 on the two sides of the groove 9 are respectively connected through the inelastic dustproof cloth 8, on one hand, the inelastic dustproof cloth 8 can limit the maximum sliding-out displacement of the movable valve plate 52, and the movable valve plate is prevented from interfering with the inner wall of the valve housing 3; on the other hand, the phenomenon that the movable valve plate 52 slides unsmoothly can be prevented from occurring when polyacrylamide particles enter the groove 9, and the scalability of the valve plate 5 is fully ensured. A spring is arranged between the movable valve plate 52 and the fixed valve plate 51 in the groove 9, the movable valve plate 52 has a trend of being far away from the fixed valve plate 51 under the action of the spring, the free end of the movable valve plate 52 is abutted against the inner wall of the valve shell 3, and the free end of the movable valve plate 52 is an arc-shaped curved surface.
