Abstract
The utility model relates to a piston type anti-puncture gas drainer. The utility model is composed of an outer tube, an inner tuber and other parts, the utility model performs the function of preventing the coal gas leakage through a piston plate and a guiding tube arranged in the inner cavity of the inner tube and injecting a certain weight of water at the upper part of the piston plate. When the coal gas in the pipeline exceeds the certain pressure, the piston plate can be opened by utilizing the self-pressure of the coal gas, the alarming function is performed, and simultaneously the overflowing coal gas can be sealed, thereby to avoid the occurrence of the accidents. The utility model has the advantages that the structure is simple, the installation and the operation are convenient, and the security and the reliability are good.
Description
Technical field:
The utility model relates to the protective gear that uses in a kind of coal gas industry, particularly relates to the anti-breakdown coal gas drainer of a kind of piston type.
Technical background; In China's industrial trade, can use a large amount of coal gas, act as a fuel, and the transportation of these coal gas, often all be to transport by a large amount of pipelines, particularly in China present stage, emphasize today of energy-saving and emission-reduction, the CO gas that a large amount of steel mills discharge is all adopting various methods to reclaim, to reach the purpose of recycling, but in the process that reclaims tail gas, the Safety performance of pipeline is a hidden danger always, if because the air pressure of the CO of output is too high, perhaps occurs because foreign material and the water slug pipeline in the pipeline, tend to the accident of meeting accident, cause casualties.So when carrying the CO that blast furnace produced, on pipeline, all be provided with a drainage device at present every certain distance.But this drainage device, partial impurities and the water that generally also can only discharge in the coal gas to be contained, and for the excess pressure of coal gas, the pipeline breaking that causes but is provided with and fundamentally is controlled effectively and solves.
Summary of the invention:
The purpose of this utility model will provide a kind of piston type anti-breakdown coal gas drainer exactly, and it can solve the existing problem of above equipment effectively.The purpose of this utility model is achieved in that the anti-breakdown coal gas drainer of piston type is made up of outer tube, interior pipe, support block, it is characterized in that: at the inner chamber of outer tube, be provided with several support blocks; Described support block one end is that the steel plate with oblique bottom lock is welded on the inwall of outer tube, and the other end of support block and interior pipe weld together, and also are provided with the guide pipe that welds together mutually with piston plate at the inner chamber of interior pipe; Described piston plate is provided with pull bar; Tube cover plate outside the upper end of outer tube is provided with, the central authorities of described outer tube cover plate have the circular hole of pull bar turnover.The utility model is simple in structure, and fitting operation is convenient, and Safety performance is good, can utilize water to seal, and guarantees that coal gas can not can leak by any way.
Description of drawings:
Fig. 1 is the utility model structural representation;
1. outer tube, 2. support block, 3. in pipe, 4. piston plate, 5. pull bar, 6. cover plate, 7. guide pipe.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing;
In the drawings, the anti-breakdown coal gas drainer of the utility model piston type is made up of outer tube 1, interior pipe 3, support block 2, it is characterized in that: at the inner chamber of outer tube 1, be provided with several support blocks 2; Described support block 2 one ends are that the steel plate with oblique bottom lock is welded on the inwall of outer tube 1, and the other end of support block 2 and interior pipe 3 weld together, and also are provided with the guide pipe 7 that welds together mutually with piston plate 4 at the inner chamber of interior pipe 3; Described piston plate 4 is provided with pull bar 5; Tube cover plate 6 outside the upper end of outer tube 1 is provided with, and the central authorities of described outer tube cover plate 6 have the circular hole of pull bar 5 turnover.During concrete enforcement, the anti-breakdown coal gas drainer of piston type is arranged in the pipeline of coal gas blowdown, has an end setting of pull bar to make progress, after installing, inwardly inject the water of packed-piston from the circular hole of pull bar turnover; Described support block is supporting the weight of piston plate and inner chamber injection water, and piston plate is tightly pushed down support block under the pressure of water, to prevent the leakage of coal gas.And when the coal gas in the gas pipe line surpasses certain pressure, perhaps carry the pipeline obstruction of coal gas, build-up of pressure raises, this moment, coal gas will and be arranged on space between the guide pipe in the inner chamber extrusion piston plate that makes progress along the inner chamber of interior pipe, when greater than the weight of set water, piston plate will be by coal gas jack-up, this moment, piston plate was upwards withstood under the cover plate of outer tube under the effect of coal gas, the coal gas of being overflowed is closed in again in the pipeline, and will be played the effect of warning by the piston pulling rod of jack-up.During practical operation, the red ball of reporting to the police can be set at the top of push rod, or adopt the shake-up warning device to report to the police.So that the pipe fitter in time finds dangerous situation, get rid of hidden danger.After fault was got rid of, the pressure of coal gas will be got back to safe condition, and piston plate is got back to original working state under the effect of guide pipe.At this moment, the water that is overflowed just need add to certain height, and the utility model will continue to play the purpose that prevents gas leakage.
