Detailed Description
In order to facilitate a better understanding of the present invention, the present invention will be further described with reference to the following embodiments and drawings.
As shown in fig. 1-2. In the embodiment, the multi-pipeline intelligent integrated gas distribution and supply device comprises a split distributor 1, a cutting pipeline 2, an ignition pipeline 3 and a cutting pre-use pipeline 4, wherein the cutting pipeline and the ignition pipeline respectively comprise automatic operation control valves 5 connected to corresponding gas output ports of a gas distributor through corresponding pipeline joints 9; the pre-use line comprises a pre-use control valve 6 connected to a respective output port of the gas distributor, and an adaptive universal coupling 7. The distributor, the cutting pipeline and the ignition pipeline which respectively comprise an automatic operation control valve, and the pre-use pipeline which comprises a pre-use control valve and a self-adaptive universal coupler are arranged to form a multi-channel air supply switching combination integrated body.
The multi-path gas supply switching combination integrated body comprises a gas input port 10 of a gas distributor, an output port of a self-adaptive universal coupler forms a cutting gas output port of a cutting gun, and an output port of an automatic operation control valve of an ignition pipeline forms an ignition gas output port of the cutting gun.
During installation, the installation can be completed only by connecting the hexagonal external thread pipe joint 9a of the input port of the gas distributor to the external gas supply pipeline and connecting the hexagonal external thread pipe joint of the output port of the straight-through type self-displacement flow conversion chamber and the output port of the automatic operation control valve of the ignition pipeline to the cutting gas channel and the ignition gas channel inlet of the cutting gun.
In this example, the adaptive universal coupler comprises a straight-through type self-displacement flow-changing chamber 7a, the whole inner peripheral wall of the straight-through type self-displacement flow-changing chamber is provided with self-lengthening connection coupling threads 7b in the whole length, one side wall of the straight-through type self-displacement flow-changing chamber corresponding to the straight-through type self-displacement flow-changing chamber is provided with a radial flow-changing port 8 connected with a pre-used control valve of a pre-used pipeline, and the flow-changing port is formed by a full threaded hole.
The self-adaptive universal coupler also comprises a self-displacement coupling hole 7c which is arranged on one corresponding side wall of the straight-through type self-displacement flow-changing chamber, is long along the length direction of the straight-through type self-displacement flow-changing chamber, has the length larger than the corresponding diameter of the flow-changing port or the full threaded hole of the flow-changing port and is connected with the flow-changing port and the inner cavity of the self-displacement flow-changing chamber.
The self-adaptive universal coupler is connected with the output port of the pre-used control valve through a full threaded hole of the straight-through type self-displacement flow conversion chamber and through corresponding threaded pipe connectors and the like, and is connected with the output port of the automatic operation control valve of the cutting pipeline and the cutting air channel of the cutting gun through corresponding hexagonal external thread pipe connectors 9a through self-length connecting coupling threads 7b of the straight-through type self-displacement flow conversion chamber.
The output port of the automatic operation control valve hand of the ignition pipeline is connected with the ignition channel of the cutting gun through a hexagonal external thread pipe joint.
Due to the structural characteristics of the self-displacement flow-changing chamber and the self-lengthening connection coupling thread thereof, the physical position of the self-displacement flow-changing chamber can be automatically changed and adjusted through different connection depths of corresponding connecting pipe joints (in this case, hexagonal external thread pipe joints) connected with two ends of the self-lengthening connection coupling thread, so that reliable butt joint assembly can be accurately carried out on the self-displacement flow-changing chamber and a pre-used control valve which is changed at a certain installation position. The method has strong assembly adaptability, and can greatly reduce the requirements on the assembly precision of processing and manufacturing of parts such as connecting pieces, valves and the like. Time, labor and cost are saved. Meanwhile, no matter the self-variable length connecting coupling thread is connected to the body position, the self-variable length connecting coupling thread can always ensure that the flow change port is reliably communicated with the self-variable position flow change chamber through the self-variable position coupling hole.
The pre-use control valve may be constituted by an angle type cut-off valve. When the automatic operation control valve of the cutting pipeline breaks down during operation, the switching can be immediately carried out by opening the pre-use control valve, the cutting gun is cut by gas of the pre-use pipeline for gas supply, and the normal operation of corresponding continuous casting cutting is ensured. The preliminary control valve is closed in the normal operation state.
The automatic operation control valve can be an electromagnetic valve, the electromagnetic valves of the ignition pipeline and the cutting pipeline are connected with the corresponding automatic cutting gun controller, and the automatic ignition and the automatic cutting operation of the cutting gun are controlled by the automatic controller. The pre-use control valve may be manual or automatic.
The self-adaptive universal coupler is arranged in a hexagon nut type, and a fastening force applying part of the self-adaptive universal coupler is formed by the peripheral wall surface of the hexagon nut.
In another embodiment, the pre-use control valve is an automatic control valve connected with an automatic controller, meanwhile, an automatic gas flow or pressure detector connected with the automatic controller is arranged at the output end of the automatic displacement flow switching chamber of the cutting pipeline, when the cutting gas flow or pressure detector detects that no flow or pressure exists or is lower than a normal value, the cutting pipeline electromagnetic valve or a corresponding pipeline system of the cutting pipeline electromagnetic valve fails, the automatic controller controls the pre-use control valve to open, and the pre-use pipeline system supplies gas to the cutting gun. The flow or pressure detector type, the automatic controller and its control structure mode can be the same as the existing control detection mode. The rest of the structure and the corresponding control operation mode of this example can be similar to the above-mentioned embodiment.
