Description

Technical Field

[0001] The utility model relates to the technical field of material cut-off valves, in particular to a clearing type material cut-off valve. Background Art

[0002] The shut-off valve usually changes the size of the internal channel of the valve by moving the valve core, thereby controlling the material flow. When the valve core is completely closed, it can prevent the flow of material; when the valve core gradually opens, the material can pass through the valve at a certain flow rate. Nowadays, the shut-off valve has the effect of clearing the material.

[0003] The prior art, such as the utility model with publication number CN219949788U, provides a device for quickly cleaning a cut-off valve, comprising a raw material cavity, the raw material cavity being provided with a first discharge port; an air-material mixing cavity connected to the raw material cavity, the first discharge port extending to the left and protruding from the raw material cavity and being located in the air-material mixing cavity; the device is characterized in that it also comprises a baffle arranged in the air-material mixing cavity for blocking the first discharge port; a cylinder driving the baffle to block and open the first discharge port; and an air inlet duct, the air inlet duct comprising an air inlet, the air inlet being connected to an expansion The air section and the air expansion section have a wider diameter than the air inlet and are longer than the air inlet, the air expansion section is connected to the air-material mixing chamber, the air expansion section is connected to the second discharge port, and a fan is provided at the air inlet. The utility model can quickly take away the raw materials, improve efficiency, save energy consumption, and solve the problem that the existing air inlet duct only uses a single duct to induce air, which is easy to generate vortex and cannot quickly fill the air in the pipe. In addition, the air expansion section is too short, and the air is not completely dispersed into the air-material mixing chamber, which is easy to generate turbulence, making it impossible to extract the raw materials in the wall, affecting the cleaning efficiency of the raw materials in the air-material mixing chamber.

[0004] In daily work, it is found that when the existing emptying type cut-off valve is used, the observation port glass on the surface of the cut-off valve is easily contaminated with adsorbed impurities due to long-term use of material discharge and cutting, which affects the operator's real-time observation of the material flow, cut-off status and equipment operation status inside the cut-off valve. When the contamination is serious, the observation port glass needs to be removed, which makes the operation troublesome and inconvenient to clean, which leads to the problem that the existing emptying type cut-off valve is not convenient for cleaning the observation port glass of the cut-off valve.
