Technical Field

[0001] This utility model relates to a homogenizing valve assembly for low-pressure single emulsification. Background Technology

[0002] Currently, the high-pressure homogenizers on the market, according to a search, include a patent: "An Emulsification Module Suitable for Primary Emulsion Preparation in High-Pressure Homogenizers" (CN202323550920.4). This module comprises an emulsification shell, an emulsification chamber within the shell, an oil phase inlet connected to the top of the shell, an oil phase outlet pipe connected to the inlet within the chamber, an oil phase outlet hole on the outlet pipe, a water phase inlet connected to the chamber on one side of the shell, a rotating dispersing plate located below the oil phase outlet hole within the chamber, and an outlet connected to the chamber at the bottom of the shell. Emulsification is typically completed using a two-stage valve assembly, which usually includes two sets of homogenizing valves totaling six components; using two sets increases costs.

[0003] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of homogenizing valve assembly for low-pressure single emulsification, making it more industrially valuable. Utility Model Content

The corrugated structures on the valve seat and valve core are identical, with a depth of 0.5 mm to 1 mm, a bottom width of 1 mm to 2 mm, and a 60° arc.

[0007] Preferably, in the homogenizing valve assembly for low-pressure single emulsification, the valve seat is connected to the working chamber via a valve seat sealing ring.

[0008] Preferably, in the homogenizing valve assembly for low-pressure single emulsification, the depth of the wave structure is 0.8 mm and the width is 2 mm.

[0009] Preferably, in the homogenizing valve assembly for low-pressure single emulsification, a top rod sealing ring is fitted on the top rod.

[0010] Preferably, in the homogenizing valve assembly for low-pressure single emulsification, the length of the feed channel is between 5 mm and 8 mm.

[0011] Preferably, in the homogenizing valve assembly for low-pressure single emulsification, the length of the feed channel is 5 mm.

[0012] By means of the above solution, this utility model has at least the following advantages:

[0013] This invention can complete homogenization in one step without multiple processing steps, avoiding the use of a circulation tank, reducing production costs, and is simple to install and easy to use.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings. Attached Figure Description

[0015] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0016] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0019] Example

[0020] like Figure 1 As shown, a homogenizing valve assembly for low-pressure single emulsification includes a valve body 1, a working chamber within the valve body 1, a discharge channel 2 communicating with the working chamber on the valve body 1, a valve seat 3 connected within the working chamber, a feed channel 4 communicating with the discharge channel 2 on the valve seat 3, a push rod 5 connected within the working chamber, and a valve core 6 connected to the push rod 5. The valve core 6 is disposed opposite to the valve seat 3. A wave structure 8 is provided on the inner surface of the valve seat 3, and a wave structure is provided on the inner surface of the valve core 6 opposite to the wave structure of the valve seat 3. The wave structures on the valve seat 3 and the valve core 6 are identical, with a depth of 0.5 mm to 1 mm, a bottom width of 1 mm to 2 mm, and an arc of 60°.

[0021] In this invention, the valve seat 3 is connected to the working chamber via a valve seat sealing ring 7, and a top rod sealing ring 9 is fitted onto the top rod 5. This improves the sealing performance.

[0022] The wave structure described in this invention has a depth of 0.8 mm and a width of 2 mm.

[0023] The length of the feed channel 4 in this invention is between 5 mm and 8 mm, wherein the length of the feed channel 4 is 5 mm. Using a longer feed channel can reduce the slowdown speed, allowing the material in the homogenization section to be homogenized better and more fully.

[0024] The working principle of this utility model is as follows:

[0025] In practical operation, the homogenizing valve of this utility model works on the same principle as the homogenizing valve in the prior art, except that a wave structure is used in the homogenization section, so that the material entering from the feed channel is repeatedly sheared by the wave structure. Each shearing will reduce the size of the product and eventually achieve emulsification.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
