Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically a high-resistance piston-type universal ventilation valve. Background Technology

[0002] A ventilation valve is a device that controls airflow, allowing air to enter or exit a space as needed, thus providing ventilation. A piston-type ventilation valve is a specific type of ventilation valve whose working principle is based on piston movement. It typically includes a piston assembly that slides within the valve body. By changing the position of the piston, the opening and closing of the airflow or the regulation of the air volume is controlled. This type of valve offers good sealing and stability.

[0003] In the prior art, when a ventilation valve is used, the valve cover moves inside the valve after being impacted by airflow, thus closing the valve. However, because there is no adequate protection between the valve cover and the valve, when the valve cover is closed by external force, a hard collision occurs between the inner wall of the valve and the valve cover. This is not conducive to reducing the damage caused by collisions and impacts to the valve cover and the valve, and is not conducive to improving the impact resistance of the ventilation valve. Therefore, in order to solve the above problems, a high-resistance piston-type universal ventilation valve is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a high-resistance piston-type universal ventilation valve to solve the problem mentioned in the background art that, due to the inability to adequately protect the valve cover and the valve, when the valve cover is closed by external force, a hard collision will occur between the inner wall of the valve and the valve cover, which is not conducive to reducing the damage caused by collision and impact to the valve cover and the valve, and is not conducive to improving the impact resistance of the ventilation valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-resistance piston-type universal ventilation valve, comprising a door body, a valve cover movably connected to the inner side of the door body, a lever assembly provided on the surface of the door body, and a sealing ring fixedly connected to the inner wall of the door body;

[0006] The inner side of the door is provided with a protective mechanism, which includes a fixed rod that is fixedly connected to the surface of the door. The inner side of the fixed rod has a movable groove, and a spring is fixedly connected to the inner wall of the movable groove. A movable rod is fixedly connected to the surface of the spring, and a damping element is fixedly connected to the inner wall of the movable groove.

[0007] Preferably, the protective mechanism further includes a buffer pad, which is fixedly connected to the surface of the valve cover, and a groove is provided on the inner side of the door body.

[0008] Preferably, one end of the spring is fixedly connected to the movable groove, and the other end of the spring is fixedly connected to the movable rod, which moves within the movable groove and the inner side of the door.

[0009] Preferably, the end of the movable rod away from the spring is fixedly connected to the valve cover, one end of the damping element is fixedly connected to the movable groove, and the other end of the damping element is fixedly connected to the movable rod.

[0010] Preferably, the surface of the door is provided with a locking mechanism, the locking mechanism including a fixing block, the fixing block being fixedly connected to the surface of the valve cover, a limit groove being formed on the inner side of the fixing block, a connecting block being fixedly connected to the surface of the door, a screw being movably connected to the inner side of the connecting block, a motor being fixedly installed on the inner side of the connecting block, a moving block being threadedly connected to the surface of the screw, and a plug being fixedly connected to the surface of the moving block.

[0011] Preferably, the limiting grooves are formed in two sets on the inner side of the fixed block, the screw is fixedly connected to the output end of the motor, the insert rods are formed in two sets and fixedly connected to the moving block, and the insert rods are movably connected to the connecting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting up a fixed rod and a movable rod, when the valve cover is impacted by airflow and moves, the movable rod moves within the movable groove, causing the spring to deform. Through the elastic properties of the spring and the setting of the damping component, the impact energy can be absorbed and dispersed, reducing the direct impact of the valve cover on the inner wall of the door, thereby reducing the impact on the door body and making the door body and valve cover less prone to damage. This helps to improve the impact resistance of the valve. At the same time, the setting of the buffer pad and the opening of the groove can avoid hard contact between the door body and the valve cover, thereby reducing damage.

[0014] 2. The motor drives the screw to rotate, which in turn moves the moving block and the insert rod. This allows the insert rod and the limiting groove to engage and disengage. When the door is closed and ventilation or exhaust is not required, the engagement of the insert rod and the limiting groove locks and secures the fixing block and the connecting block, thus limiting the valve cover and making it more stable and less likely to be opened.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] The motor 34 used in this application is a product that can be purchased directly from the market. Its principle and connection method are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0024] A high-resistance piston-type universal ventilation valve includes a door body 1, a valve cover 11 movably connected to the inner side of the door body 1, a lever assembly 12 provided on the surface of the door body 1, and a sealing ring 13 fixedly connected to the inner wall of the door body 1. The sealing ring 13 can seal the door body 1 and the valve cover 11, thus ensuring the sealing performance when the door body 1 is closed. The valve cover 11 can be opened and closed when its position inside the door body 1 changes, thus facilitating the exhaust of gas and achieving ventilation.

[0025] A protective mechanism is provided on the inner side of the door body 1. The protective mechanism includes a fixed rod 2, which is fixedly connected to the surface of the door body 1. A movable groove 21 is opened on the inner side of the fixed rod 2. A spring 22 is fixedly connected to the inner wall of the movable groove 21. A movable rod 23 is fixedly connected to the surface of the spring 22. A damping element 24 is fixedly connected to the inner wall of the movable groove 21. Through the elastic properties of the spring 22 and the setting of the damping element 24, as well as the cooperation of the buffer pad 25 and the groove 26, the impact of airflow can be mitigated, which can reduce the direct impact of the valve cover 11 on the inner wall of the door body 1, thereby protecting the door and improving the impact resistance of the door.

[0026] Furthermore, the protective mechanism also includes a buffer pad 25, which is fixedly connected to the surface of the valve cover 11. A groove 26 is provided on the inner side of the door body 1. Through the cooperation of the buffer pad 25 and the groove 26, when the valve cover 11 closes the door body 1 under the action of impact, direct collision between the door body 1 and the valve cover 11 can be avoided, thus avoiding rigid contact.

[0027] Furthermore, one end of the spring 22 is fixedly connected to the movable groove 21, and the other end of the spring 22 is fixedly connected to the movable rod 23. The movable rod 23 moves within the movable groove 21 and the door body 1. The movable groove 21 and the movable rod 23 are connected by the spring 22, so that when the valve cover 11 moves under the action of impact, the movable rod 23 moves within the movable groove 21, which will cause the spring 22 to deform, thereby absorbing the impact to a certain extent and reducing the impact on the door body 1.

[0028] Furthermore, the end of the movable rod 23 away from the spring 22 is fixedly connected to the valve cover 11, one end of the damping element 24 is fixedly connected to the movable groove 21, and the other end of the damping element 24 is fixedly connected to the movable rod 23. By setting the damping element 24, the valve cover 11 can suppress the oscillation when it is subjected to the explosion shock wave, thereby reducing the impact of the valve cover 11 on the door body 1 and thus reducing the damage.

[0029] Furthermore, a locking mechanism is provided on the surface of the door body 1. The locking mechanism includes a fixing block 3, which is fixedly connected to the surface of the valve cover 11. A limit groove 31 is opened on the inner side of the fixing block 3. A connecting block 32 is fixedly connected to the surface of the door body 1. A screw 33 is movably connected to the inner side of the connecting block 32. A motor 34 is fixedly installed on the inner side of the connecting block 32. A moving block 35 is threadedly connected to the surface of the screw 33. An insertion rod 36 is fixedly connected to the surface of the moving block 35. By rotating the screw 33, the moving block 35 can drive the insertion rod 36 to move, thereby enabling the insertion rod 36 and the limit groove 31 to be inserted and separated, which facilitates the fixing and releasing of the fixing block 3 and the connecting block 32.

[0030] Furthermore, two sets of limiting grooves 31 are formed inside the fixed block 3. The screw 33 and the output end of the motor 34 are fixedly connected. Two sets of insert rods 36 are fixedly connected to the moving block 35. The insert rods 36 and the connecting block 32 are movably connected. By setting the insert rods 36, the insert rods 36 and the limiting grooves 31 can be inserted into each other, which can fix the fixed block 3 and the connecting block 32. Thus, when ventilation or exhaust is not required, the valve cover 11 can be limited, making it difficult for the valve cover 11 to be opened.

[0031] Working principle: When in use, when the valve cover 11 is impacted by airflow and moves inside the door body 1, the movable rod 23 will move inside the movable groove 21 under the action of the valve cover 11. At this time, the spring 22 deforms, and with the setting of the damping element 24, the impact force can be absorbed and mitigated to a certain extent. At the same time, the movement of the valve cover 11 causes the buffer pad 25 to enter the groove 26. The cooperation between the buffer pad 25 and the groove 26 can avoid hard contact between the door body 1 and the valve cover 11, and can also mitigate the impact to a certain extent, thereby improving the impact resistance of the ventilation valve.

[0032] When the valve cover 11 is closed, the movement of the valve cover 11 causes the connecting block 32 to move accordingly, and the moving block 35 to face the limiting groove 31. The motor 34 is electrically connected to an external power source. The operator starts the motor 34 by pressing the switch. The motor 34 drives the screw 33 to rotate. The moving block 35 will move under the action of the screw 33 and drive the insertion rod 36 to move accordingly. This enables the insertion rod 36 to be inserted into the limiting groove 31, thereby locking the fixed block 3 and the connecting block 32, achieving the effect of limiting the valve cover 11, and making the valve cover 11 more stable.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
