Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a novel flat valve. Background Art

[0002] At present, in the bulk grain system, the flat valve is an indispensable key component in the bulk grain transportation process, and it mainly plays an important role in opening the valve to control the discharge of materials and closing the valve to prevent leakage.

When the gate is opened for material discharge, the material is easy to enter the groove, affecting the normal closing of the gate. This design will increase the resistance of the gate during operation and cause greater wear. The front end of the gate will come into contact with the material during material discharge. Over time, the front end of the gate will have attachments sticking to it, affecting its complete closing. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a new type of flat valve.

The mounting frame is provided with a driving assembly, and the driving assembly is connected to the gate plate so that the gate plate can be connected to the material cavity or the active cavity. A receiving port that matches the size of the gate plate is provided at the front end of the material cavity so that when the gate plate blocks the material cavity, the front end of the gate plate can be connected to the receiving port.

[0007] Furthermore, the driving assembly includes a driving motor, a lead screw and a slider; the driving motor is arranged on the mounting frame and is connected to the lead screw, the lead screw is in the movable cavity and is matched with a slider, and the slider is connected to the bottom of the gate plate so that the driving motor operates to connect the gate plate to the material cavity or the movable cavity.

[0008] Furthermore, four material guide plates are provided at the material cavity, and the four material guide plates are connected end to end and are inclined inwardly to form a material discharge channel with a gradually decreasing opening to improve the material discharge effect.

[0009] Furthermore, the mounting frame is provided with through holes corresponding one to one with the rollers, the size of the through holes matches the size of the rollers and a mounting plate is connected to each through hole by bolts, the mounting plate is connected to the rollers so that the rollers can be replaced directly from the outside of the mounting frame by loosening the bolts, avoiding maintenance personnel from entering the mounting frame to operate, thereby improving safety and maintenance efficiency.

[0010] Furthermore, a scraper plate is provided at the active cavity, and the scraper plate contacts the surface of the gate plate to prevent accumulation of materials thereon during the process of the gate plate being connected to the active cavity.

[0011] Furthermore, the gate is arranged obliquely and its lowest end is connected to the receiving port to avoid accumulation of materials on the gate during the process of the gate connecting to the active cavity.

[0012] Furthermore, the roller is made of nylon.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1.
