Description

Technical Field

[0001] This utility model specifically relates to a pressure relief valve. Background Technology

[0002] Air-supported membrane structures refer to a building structure system that uses special architectural membrane materials as its outer shell and is equipped with an intelligent electromechanical system that provides positive air pressure inside the structure to support the main body. Examples include coal-fired power plants, dock storage yards, industrial warehouses, quarries, and air-supported gymnasiums.

[0003] The air pressure inside a typical air-supported membrane structure is 300-500 Pa. Excessive pressure poses a safety hazard, necessitating the use of pressure relief devices to regulate the internal air pressure. However, existing pressure relief devices have several shortcomings, such as: the inability to adjust the automatic pressure relief value; insufficient structural stability; and excessively small opening angle of the pressure relief valve, resulting in ineffective pressure relief.

[0004] To solve one of the above problems, this utility model proposes a pressure relief valve. Utility Model Content

[0005] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a pressure relief valve with the advantages of automatic pressure relief, stable structure, and adjustable pressure relief.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a pressure relief valve, installed on the side wall of an air-supported membrane structure, comprising:

[0007] Frame, valve plate, electric window opener, window opening controller, and pressure detector;

[0008] The valve plate is mounted on the frame, and the electric window opener is connected to the valve plate to drive the valve plate to open and release pressure, or to drive the valve plate to close and maintain pressure.

[0009] The pressure detector and the electric window opener are both electrically connected to the window opening controller. The pressure detector is used to detect the air pressure inside the air-supported structure, and the window opening controller can control the electric window opener to drive the valve plate to open or close based on the pressure detected by the pressure detector.

[0010] The present invention further includes a frame comprising a valve chamber and a pressure detection chamber, both of which open toward the inner side of the air-supported structure;

[0011] The valve plate is disposed inside the valve cavity, and the pressure detector is disposed inside the pressure detection cavity.

[0012] The present invention further includes a valve frame provided on the inner circumference side of the valve cavity, and the valve plate disposed within the valve frame;

[0013] One side of the valve plate is hinged to one side of the valve frame. The electric window opener is located inside the valve cavity and connected to the valve plate, and can push or pull the valve plate to make the valve plate rotate.

[0014] The present invention is further provided that the valve frame is inclined to the side away from the air-supported membrane structure, and the valve plate is hinged to the side of the valve frame closer to the air-supported membrane structure.

[0015] The present invention further comprises that the electric window opener is disposed in the valve cavity and located on the side away from the valve frame and the valve plate hinge, and the electric window opener is connected to the side of the valve plate away from the valve frame and the valve plate hinge.

[0016] The present invention is further provided that the valve frame is inclined from top to bottom toward the side away from the air-supported membrane structure, and the upper side of the valve frame is the side closer to the air-supported membrane structure;

[0017] The upper end of the valve plate is hinged to the upper side of the valve frame, and the electric window opener is located on the lower side of the valve cavity and connected to the lower end of the valve plate.

[0018] In a further embodiment of this invention, a sealing strip is provided between the valve frame and the valve plate.

[0019] The present invention further includes a ventilation mesh panel on the side of the frame near the air-supported membrane structure.

[0020] The present invention further includes a display screen, which is electrically connected to the window opening controller to display the pressure inside the air-supported structure and / or the set pressure relief pressure.

[0021] The present invention further includes a control button, which is electrically connected to the window opening controller to adjust the set pressure relief pressure and / or control the opening and closing of the valve plate.

[0022] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0023] In this invention, when the pressure detector detects that the pressure inside the air-supported structure is greater than the set pressure, the window opening controller will cause the electric window opener to drive the valve plate to open the valve, thereby relieving pressure on the air-supported structure and preventing excessive air pressure inside the structure, thus reducing safety hazards. When the pressure detector detects that the pressure inside the air-supported structure is less than or equal to the set pressure, the window opening controller will cause the electric window opener to drive the valve plate to close the valve, thereby maintaining pressure on the air-supported structure, preventing excessively low air pressure inside the structure, ensuring sufficient pressure inside the air-supported structure, and maintaining the structural stability of the air-supported structure.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0035] This embodiment relates to a pressure relief valve, installed on the side wall of an air-supported membrane structure, used to adjust the air pressure inside the structure, such as... Figure 1-7 As shown, the pressure relief valve includes: a frame 100, a valve plate 200, an electric window opener 300, a window opening controller 400, and a pressure detector 500.

[0036] The valve plate 200 is mounted on the frame 100 and is used to close the valve. Opening the valve plate 200 allows for pressure relief of the air-supported structure, while closing it allows for pressure maintenance. An electric window opener 300 is connected to the valve plate 200. The electric window opener 300 can drive the valve plate 200 to open the valve to relieve internal air pressure in the air-supported structure, or drive it to close the valve to maintain internal air pressure. Both the pressure detector 500 and the electric window opener 300 are electrically connected to the window controller 400. The pressure detector 500 is used to detect the air pressure inside the air-supported structure. The window controller 400 can obtain the pressure detected by the pressure detector 500 and control the opening and closing of the valve plate 200 driven by the electric window opener 300 based on the pressure detected by the pressure detector 500: when the pressure detector 500 detects that the pressure inside the air-supported structure is greater than the set pressure, the window controller 400 will cause the electric window opener 300 to drive the valve plate 200 to open the valve to release pressure from the air-supported structure, preventing excessive air pressure inside the air-supported structure and reducing safety hazards; when the pressure detector 500 detects that the pressure inside the air-supported structure is less than or equal to the set pressure, the window controller 400 will cause the electric window opener 300 to drive the valve plate 200 to close the valve to maintain pressure in the air-supported structure, preventing excessively low air pressure inside the air-supported structure, ensuring sufficient pressure inside the air-supported structure, and maintaining the structural stability of the air-supported structure.

[0037] In this embodiment, the frame 100 includes a valve chamber 110 and a pressure detection chamber 120. Both the valve chamber 110 and the pressure detection chamber 120 open towards the inside of the air-supported membrane structure and communicate with the inside of the air-supported membrane structure. A valve plate 200 is disposed within the valve chamber 110. By opening or closing the valve plate 200, the valve chamber 110 can connect the inside of the air-supported membrane structure to the outside, thereby relieving pressure on the air-supported membrane structure. A pressure detector 500 is disposed within the pressure detection chamber 120 to detect the air pressure inside the air-supported membrane structure. The valve chamber 110 and the pressure detection chamber 120 are independently configured to prevent air from flowing within the valve chamber 110 when the valve plate 200 is open, which could affect the detection effect of the pressure detector 500. This avoids interference from the pressure relief airflow, improves the pressure relief accuracy of the pressure relief valve, and ensures stable air pressure inside the air-supported membrane structure.

[0038] In this embodiment, a valve frame 130 is provided on the inner circumference of the valve cavity 110, and a valve plate 200 is disposed within the valve frame 130. One side of the valve plate 200 is hinged to one side of the valve frame 130. An electric window opener 300 is disposed within the valve cavity 110, and its working end is connected to the valve plate 200. It can push or pull the valve plate 200, causing the valve plate 200 to rotate, thereby changing the gap between the valve plate 200 and the valve frame 130, realizing the flow or blockage of airflow, thereby depressurizing or maintaining the pressure of the air-supported structure.

[0039] In this embodiment, the valve frame 130 is inclined towards the side away from the air-supported structure, and the valve plate 200 is hinged to the side of the valve frame 130 closest to the air-supported structure. This allows for greater airflow when the valve plate 200 is rotated open, resulting in better and faster pressure relief. As a preferred embodiment, the valve frame 130 is inclined from top to bottom towards the side away from the air-supported structure, with the upper side of the valve frame 130 being the side closest to the air-supported structure. The upper end of the valve plate 200 is hinged to the upper side of the valve frame 130.

[0040] In this embodiment, the electric window opener 300 is disposed within the valve chamber 110 and located on the side away from the hinge between the valve frame 130 and the valve plate 200. The electric window opener 300 is connected to the side of the valve plate 200 away from the hinge between the valve frame 130 and the valve plate 200, allowing the electric window opener 300 to better drive the valve plate 200 to open or close. With the same driving distance, a larger gap can be achieved between the valve plate 200 and the valve frame 130, resulting in faster pressure relief and reducing the driving distance required for the electric window opener 300. This reduces the cost and failure rate of the electric window opener 300, improving the performance of the pressure relief valve. As a preferred embodiment, the electric window opener 300 is disposed on the lower side of the valve chamber 110 and connected to the lower end of the valve plate 200 to effectively drive the opening and closing of the valve plate 200.

[0041] As a preferred embodiment, a sealing strip 600 is provided between the valve frame 130 and the valve plate 200. The sealing strip 600 can be located on the inner circumference of the valve frame 130 or the outer circumference of the valve plate 200, or both the valve frame 130 and the valve plate 200 can have sealing strips 600. When the valve plate 200 is closed, the sealing strip 600 can increase the sealing between the valve frame 130 and the valve plate 200, and the electric window opener 300 can drive the valve plate 200 to compress the sealing strip 600 to achieve a better sealing effect. The sealing strip 600 can effectively prevent air leakage from the pressure relief valve, which would affect the pressure holding effect of the pressure relief valve and thus cause insufficient air pressure in the air-supported structure.

[0042] In this embodiment, a ventilation mesh plate 700 is provided on the side of the frame 100 near the air-supported structure. The ventilation mesh plate 700 can filter out debris brought by the flowing air, effectively preventing debris from accumulating in the pressure relief chamber and causing problems such as the valve plate 200 not closing properly or the electric window opener 300 malfunctioning. At the same time, it prevents debris from entering the pressure detection chamber 120 and affecting the detection effect of the pressure detector 500. This improves the stability and accuracy of the pressure relief valve.

[0043] In this embodiment, a display screen 800 is also included. The display screen 800 is electrically connected to the window opening controller 400 to display the pressure inside the air-supported structure and / or the set pressure relief pressure, allowing users to observe and understand the internal air pressure and the set pressure relief pressure of the air-supported structure. As a preferred embodiment, a control button 900 is also included. The control button 900 is electrically connected to the window opening controller 400, and the set pressure relief pressure can be adjusted via the control button 900, or the valve can be manually opened and closed to adjust the pressure inside the air-supported structure. Of course, in other embodiments, other devices can be connected to the window opening controller 400 to set the pressure relief pressure or control the opening and closing of valves.

[0044] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
