Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of inflatable doors, in particular to an inflatable door control system and an inflatable door. BACKGROUND

[0002] In many modern fields, such as laboratories, clean workshops, warehouse facilities, and some special activity sites, inflatable doors are widely used due to their good sealing performance and the characteristics of quick assembly and disassembly. They can effectively isolate different environmental areas and prevent the mutual penetration of dust, pollutants, harmful gases, etc., or maintain specific environmental conditions such as pressure, temperature, humidity, etc. in specific scenarios.

[0003] Traditional inflatable door systems have many technical defects in actual operation, such as air path blockage and air path leakage. Air path leakage is an important factor that threatens the normal operation and sealing effect of inflatable doors. Due to factors such as long-term use, vibration, temperature changes, etc., the sealing performance of the pipe connection parts, valve sealing parts, etc. in the air path may decrease. Once air path leakage occurs, it is difficult to maintain the internal air pressure of the inflatable door at a normal level, which greatly reduces its sealing performance and cannot effectively play an isolation role, which may adversely affect the internal experimental environment, production process, or stored goods. For example, in a laboratory, it may lead to inaccurate experimental data and contaminated experimental samples; in a clean workshop, it may damage the cleanliness level and increase the rate of defective products; in a warehouse facility, it may cause the stored goods that are susceptible to oxidation, moisture, or environmental sensitivity to deteriorate and be damaged.

[0004] In order to overcome the defects of traditional inflatable door systems in terms of air path reliability, emergency handling capacity, and air inflation uniformity, there is an urgent need for an innovative inflatable door system design to meet the needs of modern fields for efficient, safe, and stable operation of inflatable doors.

The high-pressure air bag 29 is made of high-strength and high-pressure-resistant rubber material, has good sealing performance and elasticity, and in use, a certain pressure gas is filled into the high-pressure air bag 29 through the high-pressure storage tank 28. In actual use, a one-way valve can be installed between the high-pressure storage tank 28 and the high-pressure air bag 29 to keep the gas pressure in the high-pressure air bag 29 stable.

[0031] Specifically, when the control system works normally, the back blowing system is in a closed state, when the control unit determines that the main gas pipeline 8 may be blocked (such as abnormal inflation pressure rise, inflation speed significantly decreases, etc.) according to the signal of the gas pressure sensor two 18, the back blowing system is started, the back blowing electromagnetic valve one 21 is opened, the back blowing pressure and time are set, and the main gas pipeline 8 is back purged, in the process, the back blowing electromagnetic valve one 21 on the back blowing branch 24 between the pressure maintaining valve 9 and the electromagnetic valve two is first opened for back purging, then the back blowing electromagnetic valve one 21 is closed and the back blowing electromagnetic valve one 21 on the back blowing branch 24 between the pressure reducing valve 10 and the pressure relief valve 17 is opened for back purging, then the back blowing electromagnetic valve one 21 is closed and the back blowing electromagnetic valve one 21 on the back blowing branch 24 at the gas outlet end of the pressure reducing valve 10 is opened for back purging, so that the entire main gas pipeline 8 can be back purged, and in the above process, the inflation can be tried after the back purging is completed, when the inflation pressure or speed is normal, the subsequent back purging is not needed, and the above method can also avoid the phenomenon that the back purging effect is not ideal due to the long distance between the back purging port and the blocked point.

[0032] An inflation door comprises an inflation door body 30 and an inflation door control system, wherein the inflation door body 30 is rotationally connected with a door frame through a plurality of hinges 11, a male connector and a female connector in a joint 31 are respectively arranged on the hinge inner piece and the hinge outer piece on one of the hinges 11, and the male connector and the female connector are completed when the inflation door body 30 is closed.

[0033] The workflow of the embodiment is as follows: when the inflatable door body 30 is sealed, the door body 30 is closed and the magnetic lock is activated to ensure the fixation of the door body, the air pump 1 is controlled to work by the control unit to start the inflation process, and the inside of the door reaches the set air pressure; when the inflatable rubber strip 16 leaks, the emergency system starts to work to maintain the sealing state of the inflatable door body 30; when the control unit determines that the main air path pipeline 8 may be blocked according to the signal of the air pressure sensor 2 18 (for example, the inflation pressure abnormally rises, the inflation speed obviously decreases, etc.), the back-blowing system is started; when the door needs to be opened, the air release operation is first performed to reduce the air pressure in the door body, and then the power supply of the magnetic lock is disconnected, so that the door can be opened; in the case of electronic system failure, the air can be released manually through the emergency switch, thereby ensuring safety and allowing the system to be maintained.
