Description

Technical Field

[0001] The utility model relates to the technical field of flow control valves, and particularly relates to an easily assembled flow control valve. Background Art

[0002] A flow control valve is a high-precision and multi-functional flow control device, which is applicable to pipelines that need to control flow and pressure. It has characteristics such as high control sensitivity, safety and reliability, and is widely used in various occasions that require precise flow control, such as water conservancy projects, petrochemical industry, metallurgical industry, food processing and other fields.

[0003] However, the existing assembly structure of the flow control valve is single, lacking an easily assembled structure. During the assembly process, it may consume more time and labor, increase production costs, reduce assembly efficiency, and at the same time increase the difficulty of overhaul, maintenance and reassembly, resulting in an extended maintenance cycle and increased maintenance costs. Therefore, we propose an easily assembled flow control valve. Content of the Utility Model

This new type of flow control valve has an easily assembled structure, which can effectively reduce the time and labor consumed during the assembly process, improve the assembly efficiency, and can also reduce the difficulty of overhaul, maintenance and reassembly, thereby effectively reducing the maintenance cycle and saving maintenance costs.

[0005] The technical solution adopted by the utility model to solve its technical problems is an easily assembled flow control valve, which includes a flow control valve body, a first flange, a second flange, a stepping motor, a mounting bracket and a threaded interface.

[0007] By adopting the above technical solution, personnel can connect the water pipe to the flow control valve body through the threaded interfaces at both ends of the flow control valve body by threading the end of the water pipe, or can also set a flange at the end of the water pipe and connect the water pipe to the flow control valve body through the first flange and the second flange, thereby achieving the purpose of connecting the water pipe to the flow control valve body by using two connection methods of threaded connection and flange connection;

[0008] Both the first sealing washer and the second sealing washer are made of silica gel material, with a soft texture, which can closely fit with the end of the water pipe, enhance the sealing performance of the connection, and make the connection more stable.

[0009] Installing the spherical opening and closing part inside the flow control valve body helps to reduce the resistance of the fluid inside the valve. Through the stepper motor encoder, precise control can be achieved over parameters such as the rotation angle, rotation speed, and rotation direction of the stepper motor, and thus precise control can be exerted over the rotation angle, rotation speed, and rotation direction of the spherical opening and closing part.

[0010] Specifically, an installation frame is provided at the top of the flow control valve body. A stepper motor is installed at the top of the installation frame. A spherical opening and closing part is inlaid inside the flow control valve body.

[0015] Specifically, a through hole is provided at the top of the flow control valve body.

[0016] By adopting the above technical solution, the through hole facilitates the lower end of the connecting rod to pass through the flow control valve body and be connected to the spherical opening and closing part.

On the outer side of the second flange 7, there is a second sealing washer 18. Installation holes 19 are provided on the first flange 6, the second flange 7, the first sealing washer 17, and the second sealing washer 18.

[0029] During use, personnel can connect the water pipe to the flow control valve body 1 by threading the end of the water pipe and using the threaded interfaces 14 at both ends of the flow control valve body 1, or can also set flanges at the end of the water pipe and connect the water pipe to the flow control valve body 1 through the first flange 6 and the second flange 7, thereby achieving the purpose of connecting the water pipe to the flow control valve body 1 by using two connection methods: threaded connection and flange connection.

[0030] Both the first sealing washer 17 and the second sealing washer 18 are made of silica gel material, with a soft texture, capable of closely fitting with the end of the water pipe, enhancing the sealing performance at the connection, and making the connection more stable.

[0031] Installing the spherical closing member 16 inside the flow control valve body 1 helps reduce the resistance of the fluid inside the valve. Through the stepper motor encoder 12, parameters such as the rotation angle, rotation speed, and rotation direction of the stepper motor 8 can be precisely controlled, and thus the rotation angle, rotation speed, and rotation direction of the spherical closing member 16 can be precisely controlled.

[0032] Exemplarily, as Figure 1 、 Figure 2 shown, on the top of the flow control valve body 1, there is an installation frame 11. On the top of the installation frame 11, a stepper motor 8 is installed. Inside the flow control valve body 1, a spherical closing member 16 is inlaid. The top of the spherical closing member 16 is connected to a connecting rod 15, and the top of the connecting rod 15 is connected to the output end of the stepper motor 8.

[0033] During use, the stepper motor 8 can drive the spherical closing member 16 to rotate through the connecting rod 15.

[0034] Exemplarily, as Figure 1 shown, on one side of the installation frame 11, a stepper motor encoder 12 is installed by screws. The current output end of the stepper motor encoder 12 is electrically connected to the current input end of the stepper motor 8 through a wire 13.

[0035] In use, by presetting the stepper motor encoder 12 by personnel, parameters such as the rotation angle, rotation speed, and rotation direction of the stepper motor 8 can be precisely controlled using the stepper motor encoder 12.

[0036] Exemplarily, as Figure 1 shown, a reinforcement plate 9 is provided at the top of the stepper motor 8, and reinforcement rods 10 are evenly connected to the periphery of the bottom of the reinforcement plate 9, and the reinforcement rods 10 are connected to the top of the mounting frame 11.

[0040] Exemplarily, as Figure 3 shown, a through hole 21 is provided at the top of the flow control valve body 1.

[0041] In use, the through hole 21 facilitates the lower end of the connecting rod 15 to pass through the flow control valve body 1 and be connected to the spherical closing member 16.

[0042] When the present utility model is in use, personnel can connect the water pipe to the flow control valve body 1 by threading the end of the water pipe and using the threaded interfaces 14 at both ends of the flow control valve body 1. If a flange is connected to the end of the external water pipe, the water pipe can be connected to the flow control valve body 1 through the first flange 6 and the second flange 7;

[0043] Furthermore, both the first sealing washer 17 and the second sealing washer 18 are made of silicone material, with a soft texture, capable of closely fitting with the end of the water pipe, enhancing the sealing performance at the connection, and making the connection more stable;

[0044] Furthermore, the flow control valve body 1 can be reinforced through the first end plate 2, the second end plate 3, the screw rod 4, and the nut 5 to avoid the phenomenon of deformation of the flow control valve body 1 when impacted by the medium;

[0045] Furthermore, the spherical closing member 16 has smooth lines and a uniform stress area. By installing the spherical closing member 16 inside the flow control valve body 1, it helps to reduce the resistance of the fluid inside the valve;

[0046] Furthermore, through the stepper motor encoder 12, precise control of parameters such as the rotation angle, rotation speed, and rotation direction of the stepper motor 8 can be achieved.
