The device comprises a connecting rod 1, a connecting rod sleeve 2, a flashboard valve frame 3, a circular flashboard 4, a flashboard guide groove 5, a material 6, an inclined opening 7, a supporting block 8, a 9L-shaped necking and a 10L-shaped flat opening.

Detailed Description

The utility model discloses a prevent that material from unloading accumulational circular slide valve, for making the utility model discloses an aim at, technical scheme and advantage understand more clearly, below combine the attached 3-5 of drawings and embodiment, right the utility model discloses go on further the detailed description. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1:

the utility model provides a prevent that material from unloading accumulational circular slide valve, is similar with prior art, all includes slide valve frame 3, arranges in circular flashboard 4 in slide valve frame 3, the upper portion of circular flashboard 4 is provided with connecting rod 1, the connecting rod sleeve pipe 2 has been put to the cover on the connecting rod, connecting rod sleeve pipe 2 set up in slide valve frame 3's top. The connecting rod 1 drives the circular gate 4 to reciprocate up and down in the gate valve frame 3 under the driving of the driving piece to complete the opening and closing of the gate valve.

Different from the prior art, the circular gate plate 4 is provided with an inclined opening 7 at the bottom, and the bottom of the gate valve frame 3 is convexly provided with a supporting block 8 matched with the inclined opening 7. The mating is described herein as the surfaces of the two mating tangentially to form a seal. The bevel opening 7 and the supporting block 8 are mutually matched to play roles of fixing, clamping, supporting and material accumulation preventing. Specifically, the bevel 7 means that the bottom of the circular gate plate 4 is inclined, and in this embodiment, the bevel 7 is disposed in the middle of the bottom of the circular gate plate 4. The bottom of the gate valve frame 3 is smooth, the cross section of the supporting block 8 on the surface of the bottom is triangular, and the upper surface of the supporting block 8 is tangent to the lower surface of the bevel connection 7. Because the lower extreme of slide valve frame 3 has adopted the form of not having the guide slot, has avoided the material to inlay in the guide slot, and has formed the inclined plane through supporting shoe 8 for the landing that the material can be smooth can not cause material 6 to pile up, has avoided the later stage to need the manual work to carry out continuous clearance to maintain.

Example 2:

as a further preferred embodiment, further optimization is made under the same conditions as those of embodiment 1. Specifically, the circular gate plate 4 is provided with a reducing section, and a flat opening matched with the reducing section is arranged in the gate plate valve frame 3.

In this embodiment, the circular gate 4 is provided with an L-shaped reducing opening 9, and an L-shaped flat opening matched with the L-shaped reducing opening 9 is arranged in the gate valve frame 3. The diameter reducing and reducing section is from the middle to the bottom of the circular gate plate 4, the L-shaped flat opening of the gate valve frame 3 matched with the diameter reducing and reducing section is a guide groove form formed by removing the original concave part from the middle of the gate valve frame 3 to the lower part, and the smooth surface is in sealing fit with the reducing section, so that the accumulation of materials in the guide groove is avoided. Thereby effectively preventing the problems of leakage, untight sealing and the like caused by material accumulation.
