Description

Technical Field

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

[0002] In the process of industrial production, extremely high precision requirements are imposed on the control of the material conveying system. Different materials have different physical properties, such as viscosity, density, temperature sensitivity, etc. These properties directly affect the performance of the valve during the conveying process. To ensure high-precision flow control under various working conditions, the valve needs to have excellent design and manufacturing processes to adapt to a wide range of working environments. In addition, during the discharging operation, the sealing performance of the valve is crucial, which is directly related to production safety and product quality. Traditional valve designs often have difficulty in achieving long-term stable operation and high sealing performance under complex working conditions. Especially when dealing with special media (such as corrosive or highly viscous fluids), problems such as poor sealing and material leakage are likely to occur. Summary of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0023] In addition, the descriptions involving "first", "second", etc. in the present application are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0024] By providing a material control discharge valve in the embodiments of the present application, the technical problem that the discharge valve in the prior art is prone to leakage when used for different materials is solved.

[0025] The general idea of the technical solutions in the embodiments of the present application to solve the above technical problems is as follows:

[0026] As Figures 1-5 shown, the present application provides a material control discharge valve, including: a valve body 1, a valve plate 2 is arranged inside the valve body 1, the valve plate 2 is driven to move up and down by a valve rod 3, a discharge port 4 is arranged on the valve body 1, a sealing ring 5 is arranged in the discharge port 4, the valve plate 2 can be operably pressed on the sealing ring 5 to block the discharge port 4, a first retaining ring 7 is connected to the lower end of the valve plate 2 through a connecting member 6, the valve plate 2 can be operably driven to cooperate the first retaining ring 7 with the discharge port 4, and the material of the first retaining ring 7 is stainless steel or alloy steel or corrosion-resistant plastic.

[0027] During the discharging process, when the valve plate 2 blocks the discharge port 4, the valve plate 2 presses on the sealing ring 5. After the valve plate 2 is opened, the valve plate 2 drives the first retaining ring 7 to move upward, so that the first retaining ring 7 cooperates with the inner ring of the sealing ring 5. The material passes through the first retaining ring 7, and the first retaining ring 7 blocks the material, reducing the contact area and time between the material and the sealing ring 5, slowing down the aging of the sealing ring 5 to cope with the influence of different materials on the sealing ring 5.

[0028] To better understand the above technical solution, the following will combine the specification drawings and specific implementation manners to describe the above technical solution in detail.

[0029] Preferably, as Figures 1-5 shown, the connecting member 6 includes a cross bar 61 and a vertical bar 62. The vertical bar 62 is fixedly connected to the lower end surface of the valve plate 2, the cross bar 61 is fixedly connected to the inner wall of the first retaining ring 7, and the end of the vertical bar 62 away from the valve plate 2 is located inside the first retaining ring 7 and fixedly connected to the cross bar 61. Specifically, the cross bar 61 is multiple and arranged radially along the first retaining ring 7.

[0030] During the installation process, the valve plate 2, the vertical bar 62 and the first retaining ring 7 are coaxially arranged. It is preferably to select two cross bars 61, which not only play a role in stable fixation but also do not affect the flow of materials.

[0031] Furthermore, an inner shrinking ring 71 is provided at the port of the first retaining ring 7 close to the valve plate 2. During the upward movement of the first retaining ring 7, first the inner shrinking ring 71 contacts the discharge port 4. The diameter of the inner shrinking ring 71 is smaller than the diameter of the discharge port 4, which is convenient for the first retaining ring 7 to be inserted into the discharge port 4 and prevents the first retaining ring 7 from damaging the sealing ring 5 during the movement.

[0032] Furthermore, as Figures 4-6 shown, a second retaining ring 8 is fixedly arranged inside the valve body 1. The bottom surface of the second retaining ring 8 presses on the sealing ring 5. The second retaining ring 8 is fixedly connected to the valve body 1 by bolts or the second retaining ring 8 is welded to the valve body 1. The second retaining ring 8 shields the sealing ring 5 to prevent the material from contacting the upper end surface of the sealing ring 5. And after the first retaining ring 7 moves into the discharge port 4, the first retaining ring 7 cooperates with the second retaining ring 8. During the passing of the material, the narrow gap between the first retaining ring 7 and the second retaining ring 8 can reduce the contact between the material and the sealing ring 5, playing a protective role for the sealing ring 5 to prevent the sealing ring 5 from being corroded or worn.

[0033] A pressing ring 81 is arranged at the lower end inside the second retaining ring 8. After the valve plate 2 presses the sealing ring 5 and presses on the pressing ring 81, after the valve plate 2 blocks the discharge port 4, the valve plate 2 deforms the sealing ring 5 by extrusion, and the valve plate 2 also fits with the pressing ring 81, further reducing the contact between the sealing ring 5 and the material and playing a protective role for the sealing ring 5.

[0034] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications once they learn the basic creative concepts. Therefore, the appended claims are intended to be construed to include the preferred embodiments as well as all changes and modifications that fall within the scope of the present invention.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
