Description

Technical Field

[0001] This utility model relates to the field of electric dispensing valve technology, specifically an electric dispensing valve. Background Technology

[0002] A feed distribution valve is a control device primarily used for precisely controlling the flow direction and flow rate of fluids. Its basic working principle is to achieve precise control of fluid flow by changing the on / off state of the valve's internal channels or adjusting the size of the channel opening. Feed distribution valves have the advantages of simple structure and easy operation, and are widely used in various industrial automation systems. For example, in the processes of material distribution, mixing, and conveying on production lines.

[0003] A feed valve typically consists of a valve body, a valve core, and a drive mechanism. The valve body is the main body of the valve and has internal fluid passages. The valve core is the key component of the valve; its position within the valve body adjusts the flow of the passage or the size of the opening. The drive mechanism drives the movement of the valve core, and the drive method can be manual, electric, or pneumatic.

[0004] Existing material distribution valves typically have one inlet and two outlets. The valve body usually contains two sets of valve plates (A and B) and one set of baffles. The area between valve plates A and B forms a closed flow zone, with valve plate A forming flow channel 1 and valve plate B forming flow channel 2. During operation, the drive mechanism simultaneously rotates valve plates A and B clockwise or counterclockwise, opening the inlet and flow channel 1 or 2. Material entering through the inlet can then flow through flow channel 1 or 2 and exit through outlet 1 or 2, creating a diversion conveying mechanism. Simultaneously, adjusting the opening size of valve plate A or B relative to the inlet can control the material flow rate. However, in existing structures, the two valve plates are single-piece plates, which have low pressure resistance and are prone to deformation and damage under prolonged full-load conditions. In addition, although the valve plate end side is provided with a strip-shaped elastic sealing block to form a seal with the inner wall of the valve body, after long-term use, the valve plate is prone to deformation or wear and fall off, resulting in poor sealing and leakage, which affects the performance of the dispensing valve. Therefore, there is an urgent need for an electric dispensing valve to solve the above technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an electric dispensing valve to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The motor and reducer together constitute a drive device. The drive device is equipped with a brake assembly to prevent the valve core from moving accidentally during rotation. The housing has an inlet, an outlet, and a diversion port. The inlet is used to receive material, the outlet is used to output material, and the diversion port is used to divide the material into two directions. The outlet is located on the upper left side of the diversion port.

[0025] Please see Figure 1-5 An electric material distribution valve includes a housing 1, a valve plate 2 on one side of the housing 1, and a motor 8 and a reducer 9 on the top of the housing 1. The motor 8 and the reducer 9 together constitute a drive device. The drive device is equipped with a brake assembly 11 to prevent the valve core 10 from moving accidentally during rotation. The housing 1 is provided with an inlet 6, an outlet 4, and a diversion port 5. The inlet 6 is used to receive materials, the outlet 4 is used to output materials, and the diversion port 5 is used to divide the materials into two directions. The outlet 4 is located on the upper left side of the diversion port 5.

[0026] Among them, the valve core 10 is made of wear-resistant and corrosion-resistant metal or non-metal materials, with a smooth and flat surface.

[0027] The shell 1 is made by welding, and its inner surface is smooth to reduce fluid resistance.

[0028] Among them, the electric motor 8 drives the valve core 10 to rotate through the reducer 9, thereby realizing the switching of material diversion and merging.

[0029] Among them, sealing elements 3 are provided on both sides of the discharge port 4.

[0030] The lower end of the electric dispensing valve is equipped with an air connection end 7.

[0031] The working principle and usage process of this utility model: The basic structure of the electric dispensing valve includes the following:

[0032] (1) The electric feed valve housing 1 is provided with a feed inlet 6, a discharge outlet 4 and a diversion outlet 5 respectively. The feed inlet 6 is used to receive materials, the discharge outlet 4 is used to output materials, and the diversion outlet 5 is used to divide the materials into two directions. The discharge outlet 4 is located on the upper left side of the diversion outlet 5. The housing 1 is made of a material with good wear resistance and strong corrosion resistance to ensure the stability and reliability of long-term use.

[0033] (2) The valve core 10 is made of wear-resistant and corrosion-resistant metal or non-metal materials with a smooth and flat surface to ensure smooth material flow. The valve core 10 can be operated manually or driven by an electric drive device to achieve automated control.

[0034] (3) Drive device: The drive device uses an electric motor 8 and a reducer 9. The reducer 9 drives the valve core 10 to rotate, thereby switching between material diversion and merging. The drive device is equipped with a brake assembly 11 to prevent the valve core 10 from moving accidentally during rotation.

[0035] Working process: When the dispensing valve is closed, the valve core 10 tightly fits against the channel inside the valve body, preventing fluid from passing through. When the valve needs to be opened, the motor 8 and the reducer 9 drive the valve core 10 to move, creating a gap between the valve core 10 and the valve body channel, allowing fluid to flow through this gap. By adjusting the position of the valve core 10, the opening size of the channel can be controlled, thereby achieving precise control of the fluid flow rate.

[0036] Meanwhile, the valve core 10 adopts a high-quality steel plate welded structure, ensuring the strength and durability of the structure. At the same time, the valve core thickness is designed with consideration for factors such as valve diameter and operating pressure; the valve core 10 has a streamlined design: the valve core 10 is designed as a disc, with a good streamlined structure, which is consistent with the fluid flow direction during opening and closing, and can effectively reduce fluid resistance.

[0037] Furthermore, the sealing design between the valve cover and the valve body uses a rubber gasket. The sealing design between the valve cover and the valve stem uses a metal-reinforced vulcanized rubber sealing ring and a retaining ring. The arc surface of the valve core 10 is made of polytetrafluoroethylene (PTFE) elastic material; at the same time, the inner wall surfaces of the outlet and the diversion port are also made of PTFE elastic material to achieve an effective soft seal between the valve body and the valve core.

[0038] Cleaning port: An air connection end 7 is provided directly below the valve body for cleaning the valve body cavity and preventing material residue.
