Description

Technical Field

[0001] The utility model relates to the technical field of batching equipment, and more specifically, to a batching valve. Background Art

[0002] In industries like flavors and fragrances, and pharmaceutical preparation, batching is a common process, involving the metering and mixing of multiple liquid, powder, or granular ingredients according to a recipe. Typically, this process involves regulating valves to control the liquid mixing process. However, current batching valves, after long-term use, can cause liquid deposits and crystallization within the valve, leading to blockage.

[0003] Chinese patent CN 218818186U reports a flow-adjustable dispensing valve that utilizes a piston structure and a blocking assembly to achieve control of high and low flow rates. However, the valve has a complex structure, a small flow adjustment range, low dispensing accuracy, and inconvenient operation. Furthermore, liquid accumulation in the storage chamber can easily cause blockage. Summary of the Invention

[0004] In response to the defects in the existing technology, the utility model provides a dosing valve, which sets a discharge channel in the blocking component and drives the blocking component to move up and down by the power component to complete the opening and closing of the feed port, so that the feed port is connected to different discharge paths, thereby adjusting the dosing flow rate.

[0005] In order to solve the above technical problems, the utility model proposes a dispensing valve, which includes: a power assembly; a discharging cylinder installed at the bottom end of the power assembly, a discharging cavity is provided inside the discharging cylinder, and a discharging port is provided at the bottom of the discharging cylinder; and further includes:

[0006] A feed port is provided on the side wall of the discharge barrel;

[0007] The blocking component is connected to the power component, and a discharge channel that can connect the feed port and the discharge port is provided inside the blocking component. The power component drives the blocking component to move inside the discharge cavity to open and close the feed port.

[0008] Furthermore, a discharge nozzle with an adjustable inner aperture is provided at the bottom of the blocking component, and the discharge nozzle is communicated with the discharge channel.

[0009] Furthermore, a gas purge port is provided on the side wall of the discharge barrel, located below the feed port, for blowing purge gas into the discharge channel or the discharge cavity.

[0010] Furthermore, the gas purge port and the feed port are located on the same side.

[0011] Furthermore, the gas purge port and the feed port are located on different sides, and the discharge channel is provided with a through hole communicating with the gas purge port.

[0012] Furthermore, the power component drives the blocking component so that the discharge channel is located above the feed port, and the liquid feed enters the discharge cavity through the feed port and is discharged from the discharge port, thereby performing large-flow batching.

[0013] Furthermore, the power component drives the blocking component so that the discharge channel is connected to the feed port, and the liquid feed enters the discharge channel through the feed port and is discharged from the discharge port, thereby performing small flow rate batching.

[0014] Furthermore, the power component drives the blocking component so that the discharge channel is located below the feed port, and the material dispensing is stopped.

[0015] Furthermore, the feed port is connected to a feed cylinder.

[0016] Furthermore, the discharge port is arranged at the bottom of the discharge barrel.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] The dosing valve of the present invention realizes flow regulation of the dosing valve through the cooperation of the blocking component and the power component. By designing a discharge channel on the blocking component, small flow rate feeding is achieved, and the end of the discharge channel is also connected to the discharge nozzle to further control the flow rate. The flow rate regulation range is large and can meet different dosing requirements. By designing a gas purge port on the discharge barrel, the discharge channel or discharge cavity can be cleaned before and after dosing, which not only ensures the cleanliness of the dosing process and reduces the risk of crystallization blocking the discharge path, but also ensures that there is no residue of the liquid and improves the accuracy of dosing. The dosing valve of the present invention is simple to operate, and the flow control can be completed by driving the blocking component through the power component. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention.

[0028] A dosing valve, such as Figure 1-4 As shown, it includes: a power assembly 1; a discharge barrel 2 installed at the bottom end of the power assembly 1, which is provided with a discharge port 202 and a discharge cavity 201 inside; a feed port 4, which is provided on the side wall of the discharge barrel 2; a blocking assembly 5, connected to the power assembly 1, and provided with a discharge channel 501 that can connect the feed port 4 and the discharge port 202. The power assembly 1 drives the blocking assembly 5 to move inside the discharge cavity 201 to open and close the feed port 4. The power assembly 1 drives the blocking assembly 5 to move up and down inside the discharge cavity 201 to close and open the feed port 4. In the open state, the feed liquid enters the discharge channel 501 or the discharge cavity 201 through the feed port 4, which are two different discharge paths, and is discharged from the discharge port 202, completing the liquid distribution with different flow rates.

[0029] In some embodiments, Figure 1-4 As shown, the bottom of the blocking component 5 is further provided with a discharge nozzle 502 with an adjustable inner diameter, and the discharge nozzle 502 is connected to the discharge channel 501. The discharge nozzle 502 is designed with different apertures to further control the liquid flow rate.

[0030] In some embodiments, such as Figure 1-4As shown, a gas purge port 3 is further provided on the side wall of the discharge barrel 2, which is located below the feed port 4. Before and after mixing, a purge gas (such as nitrogen, etc.) can be blown into the discharge channel 501 or the discharge cavity 201 through the gas purge port 3. On the one hand, it is used for cleaning; on the other hand, it is used to clean the residual liquid therein to prevent the residual liquid from crystallizing and causing blockage.

[0031] In some embodiments, such as Figure 1-3 As shown, the gas purge port 3 is located on the same side as the feed port 4. The purge gas is blown directly into the discharge channel 501 or the discharge cavity 201 from the gas purge port 3 to clean the discharge channel 501 or the discharge cavity 201.

[0032] In some embodiments, such as Figure 4 As shown, the gas purge port 3 and the feed port 4 are located on different sides, and the discharge channel 501 is provided with a through hole connected to the gas purge port 3. The purge gas is blown directly into the discharge cavity 201 from the gas purge port 3, or blown into the discharge channel 501 through the through hole to achieve cleaning.

[0033] In some embodiments, Figure 1-4 As shown, the feed port 4 is connected to a feed cylinder.

[0034] In some specific embodiments, the power component 1 can be a cylinder, for example, a two-stroke cylinder, which can adjust the position of the sealing component 5 to open and close the feed port 4, so that the feed port 4 is connected to different discharge paths.

[0035] In some specific embodiments, the discharge port 202 is disposed at the bottom of the discharge cylinder 2 .

[0036] The working principle of this utility model is as follows:

[0037] like Figure 1 As shown, when the material dispensing stops, the power component 1 drives the blocking component 5 so that the discharge channel 501 is located below the feed port 4. At this time, the blocking component 5 fully seals the feed port 4, completing the closure of the feed port 4.

[0038] like Figure 2 As shown, during high-flow batching, the power assembly 1 drives the blocking assembly 5 so that the discharge channel 501 is located above the feed port 4. At this time, the feed port 4 is completely connected to the discharge chamber 201, and the liquid feed enters the discharge chamber 201 through the feed port 4 and is discharged from the discharge port 202. Before and after the batching process, purge gas can be introduced into the discharge chamber 201 through the gas purge port 3 to keep the chamber clean.

[0039] like Figure 3As shown, during low-flow batching, the power assembly 1 drives the blocking assembly 5 to connect the discharge channel 501 with the feed port 4. The liquid feed enters the discharge channel 501 through the feed port 4 and is discharged from the discharge port 202. After batching is completed, the blocking assembly 5 can also be driven downward to connect the gas purge port 3 with the discharge channel 501. Clean gas is blown into the discharge channel 501 to remove residual liquid feed in the discharge channel 501, ensuring batching accuracy and preventing residual liquid feed from crystallizing in the discharge channel 501 and causing blockage.

[0040] It should be noted that when dispensing with a large or small flow rate, the position of the blocking component 5 can also be adjusted to adjust the connection area between the feed port 4 and the discharge cavity 201 or the discharge channel 501, thereby achieving control of various flow rate dispensing.

[0041] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
