Description
Technical field
The utility model relates to the deslagging tailrace that is used on the fire damp pump drainage pipeline.
Background technology
Pipeline is set under coal mine gas is carried out the important measures that pump drainage is the assurance downhole safety,, have foreign material such as certain water, cinder and entered into pipeline by in the process of pipeline pump drainage gas.For avoiding pipeline blockage, need carry out deslagging to pipeline and discharge water.Chinese patent discloses a kind of deslagging tailrace that is used on the fire damp pump drainage pipeline, its primary structure is: a water intaking valve is equipped with on the top of a storage tank, this water intaking valve and a threeway are joined, floating chamber in the storage tank is connected by the interior ball float of a flexible connecting line and water intaking valve, is connected to a discharging valve in the bottom of storage tank.The shortcoming that this deslagging tailrace exists is: in the process that deslagging discharges water, water does not separate with foreign material such as cinders, be that foreign material such as water and cinder are common by entering storage tank behind the water intaking valve, and also jointly by discharging behind the discharging valve, water intaking valve and discharging valve are stopped up by foreign material such as cinders foreign material such as water and cinder easily; After the water in the storage tank was discharged some, drawdown, discharging valve promptly can cut out, and foreign material such as water in the storage tank and cinder have part and retain; When the negative pressure in the gas exhaust pipeline was excessive, discharging valve might can't be opened.
The utility model content
The purpose of this utility model is to provide a kind of gas pipeline deslagging tailrace, and it is in the process that deslagging discharges water, and foreign material such as water and cinder separate the back discharges, and the negative pressure in the gas exhaust pipeline is when excessive, and it can guarantee that also discharging valve effectively opens.
For achieving the above object, the utility model adopts following scheme: gas pipeline deslagging tailrace, it has a storage tank, the floating chamber of having taken a seat in the storage tank, the bottom of storage tank is connected to a draining valve, side at storage tank is provided with a casing, casing top is connected to the water inlet pipe that communicates with its inside, the casing lower end has opening, but the opening part in the casing lower end is provided with sealing up a door of switch, one gutter and storage tank and casing join, and make both internal communication, the outlet valve that an above inner chamber has spool is housed on the top of storage tank, passed a guide pillar in the floating chamber, on the support plate that is connected with in guide pillar upper end the guide rod corresponding with outlet valve has been housed, guide rod is stretched in the passage of outlet valve and is aimed at spool.One outlet valve of being made up of valve body, adjusting nut, spool and spring is housed on storage tank or gutter, and adjusting nut, spool and spring are contained in the valve body from top to bottom successively, have through hole on adjusting nut.
By such scheme as seen, after the water inlet pipe of the gas pipeline deslagging tailrace that the utility model provides and gas exhaust pipeline join, carry out deslagging when discharging water, foreign material such as water and cinder are entered in the casing by water inlet pipe earlier, foreign material such as cinder then natural sedimentation in the bottom of casing, water is then along with the rising of water level enters into storage tank, when the water in the storage tank reaches a certain amount of, rising by the floating chamber, by guide rod outlet valve is opened, negative pressure in the storage tank reduces, and draining valve is opened, and water is discharged from draining valve; After foreign material such as casing cinder are saved bit by bit a period of time, to open and seal up a door, foreign material such as cinder can fall discharge voluntarily.In addition, when the negative pressure in the gas exhaust pipeline is excessive, regulate pressure regulator valve, can reduce the negative pressure in the storage tank, guarantee draining valve can be normally, open smoothly.
The utility model is rational in infrastructure, dependable performance, and long service life, it can guarantee that smoothly the gas exhaust pipeline being carried out deslagging discharges water.
