Description

Technical Field

[0001] The utility model belongs to the technical field of air-tight valves for air conditioners, and in particular relates to an air-tight valve for ventilation and air conditioning. Background Art

[0002] The air conditioning sealing valve, also known as the air conditioning stop valve, is an important component in the air conditioning system. It is used to control the flow of refrigerant, help maintain the normal operation of the system and perform maintenance. Common sealing valves are divided into manual sealing valves and automatic sealing valves, both of which can achieve throttling control.

[0003] When the existing closed valve is opened for use, the internal sealing baffle will be impacted by the flowing medium in the pipeline, causing slight deformation of the sealing baffle. After the sealing baffle is closed, gaps are easily generated, affecting its sealing effect. In addition, the current sealing baffle lacks corresponding reinforcement structures, which makes it difficult to reinforce it and reduces its stability. Utility Model Content

[0021] In order to make the purpose and advantages of this utility model more clear and understandable, the following specifically describes this utility model in conjunction with the embodiments. It should be understood that the following text only describes one or several specific implementation manners of this utility model, and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] As Figures 1 - 5 shown, a closed valve for ventilation and air conditioning includes a valve body 1. There are two baffle plates 2 arranged in the inner cavity of the valve body 1. The upper and lower end faces of the baffle plates 2 are respectively fixedly connected with rotating shafts 3, and the other ends of the rotating shafts 3 are all rotatably connected with the valve body 1. Two flow guide plates 4 are fixedly connected to the inner wall of the valve body 1 near the front side. The flow guide plates 4 are arranged in a V shape, and the lengths of the two side end faces of the flow guide plates 4 are inconsistent. The length of the left side end face extending backward is less than the length of the right side end face. When the baffle plate 2 rotates, it will not be affected, and the right side end face can also be used to limit the baffle plate 2 to prevent the inclination angle of the baffle plate 2 from being too large and affecting the flow of the medium. A drive assembly and a reinforcement assembly are arranged on the top surface of the valve body 1.

[0023] As Figure 2 and Figure 5 shown, the driving assembly includes two sprocket wheels 5. The two upper side rotating shafts 3 penetrate through the valve body 1 and are fixedly connected to the sprocket wheels 5. A belt 6 is drivingly connected between the two sprocket wheels 5. A mounting plate 7 is fixedly connected to the top surface of the valve body 1. A motor 8 is mounted on the side wall of the mounting plate 7. The output end of the motor 8 is fixedly connected to the left sprocket wheel 5. The driving assembly adopts an existing conventional mechanical mechanism and is used to synchronously drive the two side baffles 2 to flip, which will not be elaborated in detail in this solution.

[0024] As Figure 2 and Figure 4 shown, the reinforcement assembly includes a push rod 10 fixedly mounted on the top surface of the valve body 1. A connecting plate 9 is fixedly connected to the output shaft of the push rod 10. Two positioning rods 11 are fixedly connected to the bottom surface of the connecting plate 9 symmetrically left and right. Two positioning holes 12 are formed on the top surfaces of the baffles 2 respectively. The positioning rods 11 correspond to the positioning holes 12.

[0025] Among them, a sealing hole corresponding to the positioning rod 11 is formed on the valve body 1. The positioning rod 11 is located in the sealing hole in the initial state. On the one hand, it plays a positioning role to ensure correspondence with the positioning hole 12 on the baffle 2. On the other hand, it plays a sealing role for the valve body 1 to prevent leakage of the valve body 1. In addition, in order to further improve the sealing effect, a sealing ring can be added at the position of the sealing hole; in addition, the push rod 10 can adopt a telescopic structure such as an electric telescopic rod or a cylinder, which is not limited in this solution.

[0026] As Figure 3 shown, a sealing strip 13 is fixedly connected to the inner wall of the valve body 1. The baffle 2 abuts against the sealing strip 13.

[0027] Specifically, the left and right end faces of the baffle 2 are respectively a convex and a concave structure, presenting a Z-shaped structure as a whole, so as to achieve an efficient sealing effect between the baffle 2 and the baffle 2, and between the baffle 2 and the valve body 1, and can withstand a large pressure, with high practicability.

[0028] As Figure 1 shown, a protective cover 14 is fixedly connected to the top surface of the valve body 1. By providing the protective cover 14, the driving assembly and the reinforcement assembly can be protected. In actual application, a maintenance cover plate can be provided on the side wall of the protective cover 14 for convenient subsequent maintenance.

[0029] The working principle of this utility model is as follows: When it is necessary to open the closed valve, first start the motor 8 to drive the left sheave 5 to rotate. The left sheave 5 drives the right sheave 5 to rotate synchronously through the belt 6. The sheave 5 drives the baffle 2 to flip synchronously by 90° through the rotating shaft 3, facilitating the opening of the closed valve. Then start the push rod 10. The output end of the push rod 10 moves downward through the connecting plate 9. The connecting plate 9 drives the positioning rod 11 to move downward, enabling it to insert into the positioning hole 12 to reinforce the baffle 2 and avoid the phenomenon of deformation of the baffle 2 caused by the impact of the medium in the pipeline, effectively enhancing the strength of the baffle 2.

[0030] The above is only the preferred embodiment of this utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of this utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
