Description

Technical Field

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

[0002] The discharge valve is an important component of the mixing vessel. Its function is not limited to controlling the discharge of materials, but also includes ensuring the complete mixing of materials and liquids and preventing material leakage. The structure and performance of the discharge valve directly affect the stability of the working performance of the mixing vessel.

[0003] In the prior art, the structure of the discharge valve includes a valve body and a valve core installed inside the valve body. The valve core is controlled to rotate by a valve stem to open or close the discharge valve. However, for a mixing container, when a conventional discharge valve is used for the discharge port, part of the material inside the mixing container will flow into the discharge valve and cannot be fully mixed, so that part of the material needs to be released during discharge to ensure product quality, thereby causing material waste.

[0011] The positioning boss is provided with a plurality of first mounting holes.

[0012] A plurality of sealing grooves are arranged on the inner wall surface of the central hole, and a single sealing groove is annular.

[0013] The structure of the second joint mechanism is as follows: it includes a connecting pipe, the interior of the connecting pipe is hollow to form a second discharge passage, one end of the connecting pipe is provided with a flange, and the other end of the connecting pipe is cooperated with a clamp, and the connecting pipe is installed with the material plug through the clamp.

[0041] In the present invention, the discharge port on the container 7 is opened at the connection between the side wall and the bottom wall, and is L-shaped. An L-shaped bend is formed between the front surface of the cover plate 101 and the plane 105, corresponding to the shape of the discharge port of the container 7; the first joint mechanism 1 can be fixedly connected to the container 7 by welding, such as Figure 6-Figure 8 As shown, the side wall surface of the cover plate 101 is abutted against the side wall surface of the container 7, and the connecting sleeve 102 is abutted against the bottom wall surface of the container 7, so that the first joint mechanism 1 is installed in the discharge port of the container 7;

[0042] In addition, by providing the plane 105, the side wall surface of the connecting sleeve 102 is flush with the bottom wall surface of the container 7, thereby preventing material accumulation.

[0044] Several sealing grooves are arranged on the inner wall of the center hole, and each sealing groove is annular. A sealing member is installed in the sealing groove to improve the sealing performance between the plug 6 and the first joint mechanism 1, and prevent the material in the container 7 from leaking into the discharge valve device when the material is stirred.

[0047] In the utility model, the valve mechanism 3 is used to control the connection and disconnection between the first discharge passage 106 and the second discharge passage 205 when the container 7 is discharged; when the valve body is opened, the first discharge passage 106 is connected to the second discharge passage 205; when the valve body is closed, the first discharge passage 106 and the second discharge passage 205 are disconnected.

[0048] The valve mechanism 3 and the first joint mechanism 1, and the valve mechanism 3 and the second joint mechanism 2 are sealed and installed through a sealing assembly; the second joint mechanism 2 is sealed and installed through a sealing ring 5 and a material plug 6. By providing a sealing assembly and a sealing ring 5, the sealing performance of the discharge valve device can be improved to prevent material leakage.

[0052] The working process of the utility model is as follows:

[0053] like Figure 6 As shown, when the container 7 is stirring, the material plug 6 is installed inside the first joint mechanism 1, the valve mechanism 3 and the second joint mechanism 2 (the valve mechanism 3 is in an open state here), and the material plug 6 is fixed by the clamp 202, so that the material plug 6 completely fills the first discharge passage 106 and the second discharge passage 205, thereby preventing the material inside the container 7 from leaking into the discharge valve device;

[0054] like Figure 7-Figure 8 As shown, when the container 7 has completed the stirring work and needs to be discharged, the clamp 202 is loosened and the plug 6 is pulled out (the valve mechanism 3 is still in the open state here), so that the material in the container 7 flows out through the first discharge passage 106 and the second discharge passage 205 in sequence;

[0055] In addition, after the material plug 6 is pulled out, the second head mechanism 2 can be connected to the material discharge pipe assembly through the clamp 202, so that the material can be transported over a long distance through the material discharge pipe assembly;

[0056] When the discharge of materials needs to be stopped, the valve core 303 is rotated by the valve stem 302, so that the valve mechanism 3 is closed to prevent the materials from flowing out.
