Description
Technical field
The utility model relates to gas-tight door technical field, especially relates to a kind of air-channel system.
Background technique
At present, airtight translation door is under the working state opening and closing, need to be to being arranged on the airbag aeration on translation every body or losing heart, realize sealing outdoors in door, for the inflation of air bag or lose heart that what adopt at present is to use two air pumps, an inflation completing air bag, another completes losing heart to air bag, this system architecture complexity, and each air pump needs respectively to provide a voltage could drive air pump work, is also a kind of waste for electric power resource.
Model utility content
The utility model aims to provide a kind of air-channel system, to solve system architecture complexity in prior art, the problem of the wasting of resources.
In some illustrative embodiment, described air-channel system comprises: air pump, be fixed at least one air bag and three-way valve on a body periphery; The first interface of described three-way valve, as suction port, is connected with described air pump; The second interface of described three-way valve, as Common Interface, is connected by air pipe with described air bag; The 3rd interface of described three-way valve is idle, as leakage port; Described three-way valve also has the valve of controlling described first interface or described the 3rd interface folding.
Compared with prior art, illustrative embodiment of the present utility model comprises following advantage:
By adopting an interface of three-way valve idle as leakage port, in the situation that needs are disappointing to air bag, leakage port is opened, closed suction port, utilize the pressure in gas circuit to be greater than extraneous pressure, automatically by the gas in gas circuit by the leakage port of three-way valve, discharge, do not need air pump of additional configuration as air releasing device, and power for air releasing device, simplify system architecture, saved electric power resource.
Brief description of the drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the system block diagram according to illustrative embodiment of the present utility model.
Embodiment
In the following detailed description, a large amount of specific detail are proposed, so that provide thorough understanding of the present utility model.But, person of skill in the art will appreciate that, also can implement the utility model even without these specific detail.In other cases, do not describe well-known method, process, assembly and circuit in detail, in order to avoid impact is to understanding of the present utility model.
Referring now to Fig. 1, Fig. 1 shows according to the block diagram of the air-channel system in some illustrative embodiment.
As shown in Figure 1, in some illustrative embodiment, disclose a kind of air-channel system that is applied in airtight translation door, having comprised: air bag 5, air pump 1, two-position three-way valve 2, pressure transducer 4, proportional relief valve 3, and gate controller 6.
Wherein, air bag 5 is connected with air pump 1 by two-position three-way valve 2, and air bag 5 is connected with two-position three-way valve 2 by air pipe, and pressure transducer 4 is arranged on air pipe with proportional relief valve 3, and gate controller 6 is electrically connected with two-position three-way valve 2 and pressure transducer 4 respectively.
In some illustrative embodiment, air bag 5 is fixed on the door body periphery of airtight translation door, is connected with one end of air pipe.At door body, under closed state, airbag aeration expands, and with the seam between seal door body and doorframe, the inside and outside realization of door is sealed, and before door body is opened, air bag loses heart, to prevent air bag wearing and tearing in the process of opening.
In some illustrative embodiment, two-position three-way valve 2 has three interfaces, is respectively first interface, the second interface and the 3rd interface, and two-position three-way valve also has a valve of controlling any two interface conductings.First interface is connected with the output port of air pump, as suction port; The second interface is connected with the air pipe the other end, as Common Interface, all the time on state.The 3rd interface is idle, as leakage port.Valve is for switching controls first interface and the second interface conducting or the 3rd interface and the second interface conducting.
In some illustrative embodiment, proportional relief valve 3 is arranged on air pipe, be communicated with air pipe, for the air pressure size in autonomous monitoring air pipe, in the time that pressure is greater than predefined threshold values, open relief opening, the gas in air pipe is discharged, while preventing that air pressure in air pipe is excessive, damage for whole air-channel system.
In some illustrative embodiment, pressure transducer 4 is arranged on air pipe, is communicated with, for detection of the concrete numerical value of the air pressure in air pipe with air pipe.
In some illustrative embodiment, gate controller 6 is open or close for controlling airtight translation door, it is electrically connected with pressure transducer, the air pressure numerical value also detecting for receiving pressure transducer, the air pressure numerical value receiving is externally shown by connected display unit, be convenient to the monitoring of personnel to air pressure.
In some illustrative embodiment, two-position three-way valve 2 is two-bit triplet solenoid valve, its valve is electromagnetic valve, be electrically connected with gate controller, receive gate controller closed maybe by the electrical signal of opening at airtight translation door, control valve is switched to first interface and the second interface on state or the 3rd interface and the second interface on state.
In some illustrative embodiment, in three interfaces of two-position three-way valve 2, at least one interface, be provided with filter screen, for the airborne impurity of filtering, prevent from that impurity from entering in gas circuit, to cause device failure.
In some illustrative embodiment, described filter screen is metal filter screen or plastic filtering net.
