Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drying equipment, and in particular relates to an electric three-way air regulating valve used in a drying ventilation system. Background Art
[0002] Temperature control is crucial during the seed drying process. Freshly harvested seeds have a high moisture content and a high metabolism. Directly drying them at high temperatures can damage their internal structure due to the rapid rate of water loss, thus affecting their vitality. Therefore, it's common practice to dry seeds at low temperatures followed by high temperatures. This helps protect the seeds' physiological structure and prevents them from losing vitality.
[0003] For single-cycle drying bins, each drying bin is equipped with an independent drying and ventilation system. The drying time and drying temperature of the drying and ventilation system are determined according to the seed batch and seed type. Drying and ventilation systems with different drying parameters are difficult to synchronize. In order to achieve a low-temperature-then-high-temperature drying method, two sets of drying and ventilation systems with different drying parameters are required, which not only increases the cost of seed drying, but also takes up too much space. In addition, the pipelines of the drying and ventilation system are complicated, and a transmission device is required between the two drying and ventilation systems, which adds additional construction costs and control difficulty. Utility Model Content
[0004] In view of this, the present invention aims to provide an electric three-way air regulating valve for a drying and ventilation system to solve the technical problem that a drying and ventilation system cannot achieve low-temperature drying followed by high-temperature drying.
[0005] In order to achieve the above-mentioned purpose, the technical solution created by the utility model is implemented as follows:
[0006] An electric three-way air regulating valve for a drying and ventilation system includes a valve body, one end of the valve body forms an air outlet, the other end of the valve body forms two side-by-side air inlets connected to the air outlet, an air volume adjustment unit is provided between the two air inlets and the air outlet, the air volume adjustment unit includes a linear actuator and a valve plate, one end of the linear actuator is fixedly connected to the valve body, and the other end of the linear actuator is hinged to the valve plate, and the valve plate is driven by the linear actuator to perform linear reciprocating motion between the two air inlets.
[0007] Furthermore, the valve body includes a frame, two upper side plates and a partition. The two upper side plates are relatively fixed at the top of the frame. The partition is connected between the two upper side plates. The two spaces enclosed by the partition and the two upper side plates constitute two air inlets.
[0008] Furthermore, the valve body also includes two lower side plates and a bottom plate. The two lower side plates are relatively fixed at the bottom end of the frame. The bottom plate is connected to the same side of the two lower side plates. The space enclosed by the bottom plate and the two lower side plates constitutes an air outlet.
[0009] Furthermore, one end of the linear actuator is fixedly connected to the frame, and the other end of the linear actuator is hinged to the valve plate through the ear plate.
[0010] Furthermore, the linear actuator is an electric push rod.
[0011] Furthermore, the frame is a frame structure surrounded by four vertical panels.
[0012] Furthermore, a reinforcement plate is fixed on the periphery of the frame.
[0013] Furthermore, slideways for the valve plate to slide are fixed on the two opposite vertical plates respectively.
[0014] Furthermore, a horizontal brace for supporting the linear actuator is connected between the two vertical plates.
[0015] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0027] An embodiment of the present invention provides an electric three-way air regulating valve for a drying ventilation system, including an electric three-way air regulating valve for a drying ventilation system, including a valve body, one end of the valve body forming an air outlet, and the other end of the valve body forming two side-by-side air inlets, one of the air inlets being connected to a high-temperature air duct, and the other air inlet being connected to a low-temperature air duct, the two air inlets being connected to the air outlet respectively, and an air volume regulating unit being arranged between the two air inlets and the air outlet, the air volume regulating unit including a linear actuator and a valve plate, one end of the linear actuator being fixedly connected to the valve body, and the other end of the linear actuator being hinged to the valve plate, and the valve plate being driven by the linear actuator to perform linear reciprocating motion between the two air inlets, thereby realizing opening and closing control of the two air inlets and regulating the hot air temperature.
[0028] The linear actuator can adopt a mechanism that generates linear motion, such as a ball screw, a pneumatic actuator, a hydraulic actuator, etc. The utility model takes an electric push rod as an example to explain in detail the structure and working principle of the electric three-way air regulating valve.
[0029] like Figure 1-Figure 3 As shown, the valve body includes a frame 101, a first upper side plate 102, a second upper side plate 103 and a partition 104. The frame 101 is a frame structure surrounded by four vertical plates. The first upper side plate 102 and the second upper side plate 103 are fixed at the top ends of the two opposite vertical plates. The partition 104 is connected between the first upper side plate 102 and the second upper side plate 103. The partition 104 divides the first upper side plate 102 and the second upper side plate 103 into two areas respectively. The partition 104 and the first area of the first upper side plate 102 and the first area of the second upper side plate 103 form a first air inlet 201, and the first air inlet 201 is connected to the high-temperature air duct. The partition 104 and the second area of the first upper side plate 102 and the second area of the second upper side plate 103 form a second air inlet 202, and the second air inlet 202 is connected to the low-temperature air duct. The first upper side plate 102 and the second upper side plate 103 are thin plate structures, and there is no restriction on their shapes. The shapes of the first upper side plate 102 and the second upper side plate 103 are adaptively adjusted for different low-temperature air ducts and high-temperature air ducts.
[0030] The valve body further includes a first lower side plate 105, a second lower side plate 106, and a bottom plate 107. The first lower side plate 105 and the second lower side plate 106 are fixed to the bottom ends of two opposing vertical plates. The bottom plate 107 is connected to the same side of the first lower side plate 105 and the second lower side plate 106. The bottom plate 107, the first lower side plate 105, and the second lower side plate 106 form an air outlet 3. The direction of the air outlet 3 can be adjusted by adjusting the positions of the first lower side plate 105, the second lower side plate 106, and the bottom plate 107.
[0031] The frame 101 serves as a load-bearing center, carrying the first air inlet 201 and the second air inlet 202 on the upper side and the air outlet 3 on the lower side. In order to improve the strength of the frame 101 , a reinforcing plate 108 is fixed to the outer side of the frame 101 .
[0032] A lug is fixed to the bottom of the valve plate 402, and the fixed end of the electric push rod 401 is fixedly connected to the frame 101. The extended end of the electric push rod 401 is hinged to the lug via a pin. The electric push rod 401 drives the valve plate 402 to perform linear reciprocating motion.
[0033] In order to ensure that the valve plate 402 moves in a straight line, slideways 109 are respectively fixed on the two opposite vertical plates, and both sides of the valve plate 402 slide in the slideways 109 .
[0034] In order to improve the stability of the electric push rod 401, a cross brace 110 is connected between the two vertical plates. The cross brace 110 is located at the bottom of the electric push rod 401 to support the upper electric push rod 401.
[0035] When the electric three-way air regulating valve is in use, the position of the valve plate 402 is adjusted by the electric push rod 401. When the valve plate 402 moves to an extreme position, the first air inlet 201 is fully opened and the second air inlet 202 is fully closed. When the valve plate 402 moves to the other extreme position, the first air inlet 201 is fully closed and the second air inlet 202 is fully opened. Therefore, by adjusting the position of the valve plate 402, it is possible to independently connect to the high-temperature air duct or the low-temperature air duct, thereby independently providing high-temperature hot air or low-temperature hot air, thus realizing the switching between high-temperature hot air and low-temperature hot air.
[0036] When the valve plate 402 moves to a position midway between the two extreme positions, both the first air inlet 201 and the second air inlet 202 are partially opened. At this point, as the first air inlet 201 becomes more open, the second air inlet 202 becomes less open. Conversely, as the first air inlet 201 becomes less open, the second air inlet 202 becomes more open. Thus, by adjusting the position of the valve plate 402, it is possible to achieve a mixture of high-temperature hot air and low-temperature hot air in varying proportions. This mixture can be used to create either low-temperature hot air for the front-end drying process or high-temperature hot air for the back-end drying process, thereby achieving dual-purpose functionality for the electric three-way air regulating valve in a drying and ventilation system.
[0037] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this disclosure can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution disclosed in this disclosure can be achieved. This is not a limitation herein.
[0038] The above specific embodiments do not limit the scope of protection of this utility model. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model shall be included within the scope of protection of this utility model.
