Description

Technical Field

[0001] This utility model relates to the field of ventilation duct valve technology, specifically to the flow guiding structure of ventilation duct valve. Background Technology

[0002] Ventilation duct valves are the core components for controlling the air volume, flow direction, and opening and closing of ventilation systems. Traditional valves mostly use manual or electric butterfly valves or air valves, which are controlled by changing the blade opening. The valve plate, valve seat, and other components of traditional valves can block the airflow, causing local airflow contraction and turbulence, increasing the resistance loss of the ventilation system. Therefore, a flow guiding structure for ventilation duct valves is proposed. Utility Model Content

[0003] The main purpose of this utility model is to provide a flow guiding structure for ventilation duct valves, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A ventilation duct valve flow guiding structure includes two flow guiding pipes arranged opposite each other. The two flow guiding pipes have flow guiding channels inside. One end of each flow guiding pipe is fixedly installed on one side of a connecting seat. The side of the connecting seat away from the flow guiding pipe is fixedly connected to one end of a connecting pipe. The interior of the connecting pipe communicates with the interior of the two flow guiding pipes. The connecting pipe, the connecting seat, and the two flow guiding pipes are all installed inside the valve body. The valve body has a valve plate inside.

[0006] By adopting the above technical solution, and by setting symmetrical guide pipes and guide cones inside the valve, the incoming airflow can be evenly divided into two streams, so that the airflow is smoothly ejected from both sides of the valve plate, no longer directly impacting the valve plate, thus avoiding the effects of airflow contraction caused by the valve plate blocking the airflow.

[0007] Specifically, the end of the connecting pipe away from the connecting seat is fixedly connected to one side of the second flange. The second flange is provided in two sets, and a tapered pipe is provided between the two sets of second flanges. The tapered pipe is connected to the interior of the connecting pipe.

[0008] By adopting the above technical solution, the ventilation duct can be fixedly connected to the tapered pipe through the second flange, allowing the airflow in the ventilation duct to flow from the tapered pipe into the interior of the connecting pipe.

[0009] Specifically, a guide cone is provided in the middle of the side of the connecting seat away from the guide pipe, and the guide cone is located inside the connecting pipe.

[0010] By adopting the above technical solution, the guide cone is used to divide the airflow and guide it into two guide tubes.

[0011] Specifically, both ends of the valve body are provided with a first flange, and the first flange and the second flange are fixedly connected by bolts.

[0012] By adopting the above technical solution, the first flange and the second flange are fastened with bolts to form a sealed connection, ensuring that the flow guiding structure is fixed inside the valve body.

[0013] Specifically, the valve body has a valve cover at its top, and a handwheel is rotatably mounted on the top of the valve cover. The handwheel is used to drive the valve plate to rotate.

[0014] By adopting the above technical solution, the operator drives the valve plate to rotate by turning the handwheel, thereby opening or closing the valve.

[0015] The beneficial effects of this utility model are:

[0016] The ventilation duct valve flow guiding structure of this utility model can evenly divide the incoming airflow into two streams by setting symmetrical flow guiding pipes and flow guiding cones inside the valve, so that the airflow is smoothly ejected from both sides of the valve plate and no longer directly impacts the valve plate, thus avoiding the effects of airflow contraction caused by the valve plate blocking the airflow.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As one embodiment of this utility model, such as Figures 1-4As shown, the ventilation duct valve flow guiding structure of this utility model includes two flow guiding pipes 9, which are arranged opposite each other. The two flow guiding pipes 9 have flow guiding channels 10 inside. One end of the two flow guiding pipes 9 is fixedly installed on one side of the connecting seat 8. The side of the connecting seat 8 away from the flow guiding pipes 9 is fixedly connected to one end of the connecting pipe 7. The interior of the connecting pipe 7 is connected to the interior of the two flow guiding pipes 9. The connecting pipe 7, the connecting seat 8, and the two flow guiding pipes 9 are all installed inside the valve body 1. The valve body 1 has a valve plate 12 inside.

[0025] When in use, when the valve plate 12 is opened, the airflow enters the connecting pipe 7 and is then divided into two streams by the guide cone 11, which flow into the guide channels 10 of the two guide pipes 9 respectively. This design ensures that the airflow is evenly sprayed from both sides of the valve plate 12, avoiding the airflow directly impacting the valve plate 12.

[0026] The present invention also includes that one end of the connecting pipe 7 away from the connecting seat 8 is fixedly connected to one side of the second flange 4, the second flange 4 is provided in two sets, and a tapered pipe 3 is provided between the two sets of the second flange 4, the tapered pipe 3 being in communication with the interior of the connecting pipe 7.

[0027] In use, the ventilation pipe can be fixedly connected to the tapered pipe 3 through the second flange 4, so that the airflow in the ventilation pipe can flow from the tapered pipe 3 into the interior of the connecting pipe 7.

[0028] The present invention also includes a flow guide cone 11 provided in the middle of the side of the connecting seat 8 away from the flow guide pipe 9, and the flow guide cone 11 is provided inside the connecting pipe 7.

[0029] In use, the guide cone 11 is used to divide the airflow and guide it into the two guide tubes 9.

[0030] This utility model also includes a first flange 2 at both ends of the valve body 1, and the first flange 2 and the second flange 4 are fixedly connected by bolts.

[0031] During use, the first flange 2 and the second flange 4 are fastened with bolts to form a sealed connection, ensuring that the flow guiding structure is fixed inside the valve body 1.

[0032] The present invention also includes a valve cover 5 at the top of the valve body 1, and a handwheel 6 is rotatably mounted on the top of the valve cover 5, the handwheel 6 being used to drive the valve plate 12 to rotate.

[0033] In use, the operator drives the valve plate 12 to rotate by turning the handwheel 6, thereby opening or closing the valve.

[0034] It should be noted that the valve plate 12 is internally equipped with a valve stem that is fixedly connected to the center of the handwheel 6, so that the handwheel 6 drives the valve plate 12 to rotate, and the position of the guide tube 9 will not hinder the rotation of the valve plate 12.

[0035] In use, the present invention first inserts the guide pipe 9, the connecting seat 8, and the connecting pipe 7 into the valve body 1, and fixes these structures inside the valve body 1 through the fixed connection of the first flange 2 and the second flange 4. Then, the ventilation pipe is fixedly connected to another second flange 4, so that the ventilation pipe is connected to the inside of the tapered pipe 3. When the handwheel 6 is turned to open the valve plate 12, the airflow in the ventilation pipe will first enter the tapered pipe 3, and then enter the connecting pipe 7 through the tapered pipe 3. After entering the connecting pipe 7, the airflow will be divided into two streams by the guide cone 11 and introduced into the guide channels 10 in the two guide pipes 9 respectively, and finally sprayed out from both sides of the valve plate 12 without directly impacting the valve plate 12.
