Description

Technical Field

[0001] This utility model belongs to the technical field of material conveying equipment, specifically relating to a material distribution valve that can achieve stepless flow adjustment. Background Technology

[0002] In various industries, material conveying pipelines often need to transport materials from the main pipeline to different paths. These paths require distribution valves to control the direction of material transport and the flow rate of materials in each branch. Traditional distribution valves are often controlled by cylinders. However, due to the limitations of cylinder structure, they typically only have two positions, allowing only changes in the direction of the material flow path.

[0003] Traditional feed valves cannot control the flow rate of materials in branch circuits. Therefore, a feed valve capable of stepless flow rate adjustment is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a feed valve that can achieve stepless flow adjustment, which solves the problem that traditional feed valves in the prior art cannot control the flow of materials in the branch.

[0005] To achieve the above objectives, the present invention provides a feed valve capable of stepless flow adjustment, comprising a valve body, a flap assembly, a servo electro-hydraulic actuator, a rotating shaft, a rocker arm, and an electrical control system. A mounting base is provided on the side of the valve body, and a servo electro-hydraulic actuator is fixedly mounted on the mounting base. A flap assembly is provided inside the valve body, and a rotating shaft is mounted on the flap assembly. A through hole is provided in the middle of the valve body, and the rotating shaft is installed within the through hole.

[0006] Preferably, the rocker arm is connected to the rotating shaft by a key, and the rocker arm drives the flap assembly to swing.

[0007] Preferably, the tail end of the servo electro-hydraulic actuator is mounted on the mounting base, and the extension rod of the servo electro-hydraulic actuator is connected to the rocker arm. The extension and retraction of the electro-hydraulic actuator causes the rocker arm to swing left and right.

[0008] Preferably, the servo electro-hydraulic actuator includes a servo motor and a hydraulic actuator system, with the servo motor controlled by an electronic control system.

[0009] Preferably, the valve body is welded from steel plate and has three channels, namely one inlet and two outlets, which can be interconnected.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. This utility model can accurately position the valve plate, which can control the direction of material flow and the flow rate of material in both channels. The flip plate is controlled by a servo electro-hydraulic actuator, which is more stable than the commonly used cylinder control and can withstand greater impact. The position of the flip plate can also be adjusted at any time during the material conveying process.

[0012] 2. This utility model has the function of stepless flow adjustment, which solves the problem that the traditional material distribution valve in the prior art cannot control the flow of materials in the branch. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, such as Figure 1-2As shown, a feed distribution valve capable of stepless flow adjustment includes a valve body 1, a flap assembly 2, a servo electro-hydraulic actuator 3, a rotating shaft 4, a rocker arm 5, and an electrical control system 7. The valve body 1 adopts a welded steel plate structure, possessing high strength and impact resistance, suitable for high-load conditions in industrial material conveying. A mounting base 11 is provided on the side of the valve body 1, integrating the actuator. The servo electro-hydraulic actuator 3 is fixedly mounted on the mounting base 11. The flap assembly 2 is located inside the valve body 1. The flap assembly 2 achieves flow distribution by changing its angle through the push of the servo electro-hydraulic actuator 3. The rotating shaft 4 is provided on the flap assembly 2, and a through hole is provided in the middle of the valve body 1, through which the rotating shaft 4 is installed. The electrical control system 7 controls the extension and retraction of the servo electro-hydraulic actuator 3, enabling the flap assembly 2 to rotate to a designated position to form a material flow channel. The electrical control system 7 integrates a servo drive + PLC control module, supports Modbus / PROFINET industrial communication protocols, and is equipped with an HMI (human-machine interface) for parameter setting.

[0020] The servo electro-hydraulic actuator 3 can be precisely extended and positioned at any location, thereby enabling the flap assembly 2 to rotate completely to one side of the valve body 1, forming a single channel to control the conveying direction of the material flow; it can also stop at any position of the valve body 1 to form two channels of different sizes, thereby controlling the flow rate of the material flow on both sides.

[0022] The rocker arm 5 is connected to the rotating shaft 4 by a key, which is a rectangular double-round-head flat key. The length is designed to be 1.5 times the diameter of the rotating shaft 4. The rocker arm 5 drives the flap assembly 2 to swing. The tail of the servo electro-hydraulic actuator 3 is mounted on the mounting base 11. The extension rod of the servo electro-hydraulic actuator 3 is connected to the rocker arm 5. The extension and retraction of the electro-hydraulic actuator causes the rocker arm 5 to swing left and right.

[0023] The servo electro-hydraulic actuator 3 includes a servo motor 31 and a hydraulic actuator system 32. The servo motor 31 is controlled by the electronic control system 7. The servo motor 31 is a Siemens 1FL6044, the hydraulic cylinder has an inner diameter of Φ50mm, the piston rod is a Φ25mm hard chrome plated rod, and the system pressure is 16MPa with an accumulator buffer.

[0024] The valve body 1 is welded from steel plates and has three channels: one inlet and two outlets. The three channels are interconnected. The plate thickness is 20mm for the inlet section and 16mm for the branch section. The three channels are arranged in a Y-shape.
