Pressure gas supply pipes 33 and 34 connected to the pressure gas supply source 32 are connected to a pressure gas supply solenoid valve 35, gate valves 36 and 37, and an exhaust solenoid valve 38, respectively.
39, 40, 41, and 42, and normally one of the inner and outer systems is used to supply and exhaust pressure gas to either one of the rubber pipe parts 30, 31. Some have already been developed. That is, in the conventional device described above, when supplying pressure gas from the pressure gas supply source 32 to the rubber pipe portion 31 of the outer inflation seal, when a sealing command is received from the control panel (not shown), the gate valve 36 operates as follows. The gate valve 37 and the pressure gas supply solenoid valve 35 are opened, and the pressure gas (in this embodiment, N 2 ) from the pressure gas supply source 32 is closed.
Gas is used. ) is supplied to the rubber pipe section 31 through the pressure gas supply pipe 34, and the gas pressure in the rubber pipe section 31 is set to a predetermined pressure (for example, 0.8 kg/
cm 2 ), the pressure gas supply solenoid valve 35 is "closed" and sealing is performed. In addition, in the case of exhaust (seal gas release), when a command to release the seal is issued from the control panel (not shown), the exhaust solenoid valves 38, 39, and 40 are opened, and the pressure inside the rubber pipe section 31 is The pressure gas inside the rubber pipe section 31 is naturally released due to the difference between the inside air and the outside air (atmospheric pressure), and the seal is released.

Since it is a natural release type that exhausts the pressure gas inside the rubber pipe section 31 due to the pressure difference between the inside gas pressure and the outside air, it takes time (approximately 15 to 16 seconds or more) for the pressure gas to completely escape, and the seal will be released. Not only does this take a considerable amount of time, but if the sealed state continues for a long period of time, there is a problem in that the rubber pipe cannot return to its original state (form before pressure gas is supplied).

The refrigerator is equipped with a front chamber equipped with a conveyor device, and an openable and closable heat-insulated door equipped with a rubber pipe-type inflation seal that can keep the front chamber airtight on the side of the main room of the refrigerator and on the outside of the front chamber. In the automated gas cold storage warehouse, the rubber pipe part of the inflatable seal is equipped with a pressure gas supply pipe connected to a pressure gas supply source and equipped with a pressure gas supply solenoid valve and a gate valve, and a pressure gas exhaust solenoid connected to a suction blower. Since it is connected to a pressure gas exhaust pipe equipped with a valve, a gate valve, and a check valve, the pressure gas inside the rubber pipe part of the inflatable seal can be forcibly released by using a check valve and a suction blower. As a result, the pressure gas can be released in a shorter time than the conventional natural release type that simply uses the pressure difference between the pressure inside the rubber pipe and the outside air (atmospheric pressure). In addition to being able to release the seal completely and quickly, it is also possible to reliably restore the rubber pipe to its original state even if the seal continues for a long time, and even if the suction blower breaks down. According to the present invention, the check valve is of a swing type and is always open by about 1 mm to 2 mm, and by adjusting it to facilitate release, it has various effects such as being able to vent seal gas. be.
