Description

Technical Field

[0001] The utility model belongs to the technical field of air film buildings, and particularly relates to an air film interlocking door system with automatic pressure relief. Background Art

[0002] In the field of air film buildings, with the continuous development of technology and the expansion of the application scope, the requirements for the internal environment control and safety performance of buildings are increasing day by day. As a lightweight, environmentally friendly and energy-saving building form, a certain air pressure needs to be maintained inside the air film building to support the membrane structure and ensure the stability and safety of the building. However, while this air pressure maintenance mechanism brings many advantages, it also poses technical challenges to the design of the entrances and exits of air film buildings, especially the interlocking door system.

[0003] In the case of a large pressure difference between the inside and outside, traditional air film interlocking door systems often have problems such as difficult door opening, large resistance, and easy damage to the door body and door opening and closing machine. This is mainly because when the indoor air pressure is much higher than the outdoor air pressure, the air pressure difference on both sides of the door leaf will form a huge resistance, making the door opening process laborious and likely to cause damage to the door body.

[0004] To solve this problem, some improved air film interlocking door systems have emerged on the market, such as the design of using a manual regulating valve for air pressure balance. However, these systems still have many deficiencies in actual application. For example, the manual regulating valve requires manual operation by the user, which is not only cumbersome and error-prone, but may also lead to inaccurate air pressure adjustment due to improper operation, thus affecting the door opening effect. In addition, the response speed of the manual regulating valve is slow and cannot quickly adapt to air pressure changes, resulting in difficulty in effectively reducing the door opening resistance when the air pressure difference is large. Therefore, it is particularly important to develop an interlocking door system that can automatically sense air pressure changes and automatically adjust the air pressure. Content of the Utility Model

[0005] Aiming at the above problems, the purpose of the utility model is to provide an air film interlocking door system with automatic pressure relief, which solves the problems that traditional air film interlocking door systems often have difficult door opening, large resistance, and easy damage to the door body and door opening and closing machine in the case of a large pressure difference between the inside and outside.

Detailed implementation mode

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0037] Example 1:

[0038] As Figure 1As shown in FIG. 4: An automatic pressure relief air film interlocking door system includes two interlocking doors 2, a buffer chamber 3, an automatic pressure relief valve 6 and a control mechanism. The two interlocking doors 2 are respectively installed on both sides of the buffer chamber 3 for connecting the indoor and outdoor. The automatic pressure relief valve 6 is installed on the interlocking door 2. The control mechanism includes a door opener 4 and a two-color indicator switch 8. The door opener 4 is installed on the door frame 1 and is used to drive the interlocking door 2. The interlocking door 2 is rotatably installed on the door frame 1 through a load-bearing hinge 9. A door opening is provided on the buffer chamber 3 for fitting and installing the door frame 1. The two-color indicator switch 8 is arranged on the wall surface of the buffer chamber 3 on both the inside and outside of the interlocking door 2. Through the linkage structure of the automatic pressure relief valve 6, it effectively solves the problem of opening the interlocking door of the air film building under high air pressure difference, reduces the opening resistance, and improves the safety and reliability of the system. It prolongs the service life of the interlocking door 2 and the door opener 4, reduces the failure rate, and reduces the maintenance cost. It meets the opening requirements under higher internal and external pressure differences, breaks through the limitations of common products on the market, and improves the practicability and applicability of the air film building. The door frame 1 is a frame structure composed of welded steel pipes. The interlocking door 2 includes a door leaf outer frame 21 and tempered laminated glass 22. The door leaf outer frame 21 is a frame structure formed by welding steel pipes. The tempered laminated glass 22 is fixed on the door leaf outer frame 21. The door frame 1 can provide stable support for the interlocking door 2, and the door leaf outer frame 21 in the interlocking door 2 can ensure the stability of the overall structure of the interlocking door 2. A threshold 10 is arranged in the door opening of the buffer chamber 3 below the door frame 1. A floor stop 11 is arranged on the threshold 10. Rubber sealing strips 12 are arranged on both the floor stop 11 and the side surface of the door frame 1 facing the interlocking door 2. The rubber sealing strips 12 play an effective sealing role to ensure the sealing performance at the connection between the interlocking door 2 and the door frame 1. The opening directions of the two interlocking doors 2 both open towards the high-pressure side indoors. When the internal pressure of the buffer chamber 3 is adjusted by pressure relief to a small difference from the internal and external pressures, the door opener 4 can drive the interlocking door 2 to rotate and open with a small load. Pull handles 7 are arranged on both the inside and outside of the interlocking door 2. Operators can push and pull the interlocking door 2 labor-savingly through the pull handles 7. The interlocking door 2 is designed as a pair of opening door bodies. An electric door opener 4 is arranged between one of the door leaf outer frames 21 of the two interlocking doors 2 and the door frame 1, and a mechanical door closer 13 is arranged between the other door leaf outer frame 21 and the door frame 1. The pair of opening design can reduce the load of the door opener 4 while ensuring the passability of the door frame 1 by manually opening the other door leaf outer frame 21. A magnetic lock 5 is arranged between the two door leaf outer frames 21. The magnetic lock 5 can play a role in stably connecting the two door leaf outer frames 21.

[0039] The working principle of this technical solution is as follows: The control of the dual-color indicator light switch 8 over the automatic pressure relief valve 6 and the door opener 4 can be achieved through relays and PLCs in existing conventional technologies. When the indoor air pressure is higher than that in the buffer chamber 3, and the air pressure in the buffer chamber 3 is higher than that outdoors, touching the dual-color indicator light switch 8 turns on the indoor door. At this time, the automatic pressure relief valve 6 on the indoor door opens for pressure relief, allowing the indoor air pressure to enter the buffer chamber 3, increasing the air pressure in the buffer chamber 3, thereby balancing the air pressure on both sides of the door and reducing the resistance when the door is opened. After the automatic pressure relief valve 6 has been open for a certain period, such as 2 seconds, the door opener 4 operates to drive the inner door of the interlocking door 2 to open, and personnel enter the buffer chamber 3. When opening the outdoor door, press the dual-color indicator light switch 8 that controls the outdoor door, causing the automatic pressure relief valve 6 on the outdoor door to open, discharging the air pressure in the buffer chamber 3 to the outdoors, reducing the air pressure in the buffer chamber 3, thereby balancing the air pressure on both sides of the door and reducing the resistance when the outdoor door is opened. Subsequently, the door opener 4 operates to drive the outer door of the interlocking door 2 to open, and personnel go outdoors. The operation principle for entering the indoor area is the same as described above.
