Abstract
The utility model discloses a drainage device of a gas drainage pipeline, which comprises a tee connected in series with the valley of the gas drainage pipeline, the lower end of the tee is connectedwith a container, the lower end of the container is connected with a normally opened ball valve and is connected with a water reservoir through a high-pressure conduit, and a water drain valve is mounted on the bottom of the water reservoir. The utility model improves the effect of gas drainage, and cannot produce negative pressure to damage drainage equipment.
Description
Technical field
The utility model relates to the colliery pipeline that draws out methane.
Background technology
When under coal mine, drawing out methane, need in the tunnel, to lay extraction pipeline.Because the tunnel fluctuations along the seat earth driving is big, the pipeline injustice, pocket accumulated slag ponding, form bigger resistance, cause bigger difficulty for the draining of gas drainage under suction pipeline, deslagging, have a strong impact on the gas drainage under suction effect, and the extra negative pressure that increases is damaged gas suction pump and fixture easily.
Summary of the invention
The purpose of this utility model is for solving the deslagging problem that discharges water of gas drainage under suction pipeline, designing a kind of tailrace.
Technical scheme is, it comprises the threeway that is serially connected in the low-lying place of gas drainage under suction pipeline, and the threeway below connects container, the ball valve of often opening arranged below the container, connects water receiver by pressure duct, and discharging valve is installed at the bottom of the water receiver.
The utility model has the advantages that often the ponding accumulated slag falls into water receiver, when ponding was full, the ball valve of container below was closed, and opens the water receiver bottom blow valve and can discharge.Because the low-lying place of pipeline is accumulated slag ponding no longer, has improved the gas drainage under suction effect, can not reproduce into negative pressure and damage extraction equipment.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Marginal data: 1---extraction pipeline; 2---threeway; 3---container; 4---the valve of often kicking off; 5---pressure duct; 6---water receiver; 7---discharging valve.
The specific embodiment
As shown in Figure 1, the utility model is included in the threeway 2 at serial connection gas drainage under suction pipeline 1 low-lying place, and threeway 2 belows are connected with container 3, the valve 4 of often kicking off is arranged below the container 3, and connects water receivers 6 by pressure duct 5, and discharging valve 7 is installed at 6 ends of water receiver.
Claims (1)
1, a kind of gas drainage under suction pipeline tailrace is characterized in that it comprises the threeway that is serially connected in the low-lying place of gas drainage under suction pipeline, and threeway below connects container, the ball valve of often opening is arranged below the container, connects water receiver by pressure duct, and discharging valve is installed at the bottom of the water receiver.
