The utility model discloses a kind of coal gas draining valve, including base, transverse pipe is filled on base, one end of transverse pipe is closed, and the other end is sewage draining exit, and sewage draining exit is provided with door；Longitudinally disposed gas condensed water inlet pipe and longitudinally disposed water cavity is filled in transverse pipe, the bottom of the gas condensed water inlet pipe and water cavity communicates with transverse pipe, the water cavity bottom sets discharge outlet, discharge outlet is communicated with overflow water channel, the flap of closing discharge outlet is set in discharge outlet, and flap is connected by swing rod with ball float；Liquid level gauge is set on water cavity wall.The utility model is rational in infrastructure, good working effect, and original " water trap（Drainage seal tank）Or the water trap with device for preventing leakage " compare, there is more safe and efficient draining, sealed reliable, easy to maintenance.
Description
Technical field
The utility model is related to a kind of coal gas draining valve.
Background technology
Existing coal gas draining valve has been widely used on gaspipe network, but pipeline is high before blast furnace gas TRT
Pressure system（Gas pressure is general in 150-300KPa or so）The multi-stag water seal drainage valve using effect for using is not good, the draining
Valve is often in off position, main cause：Gas pressure is big, and draining valve cabin is more, and exhaust, sewage draining exit are more, and water seal is easy
Failure, recovers difficulty big after failure.
The content of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, coal gas draining valve of good working effect.
Technical solution of the present utility model is：
A kind of coal gas draining valve, it is characterized in that：Including base, transverse pipe is filled on base, one end closing of transverse pipe is another
It is sewage draining exit to hold, and sewage draining exit is provided with door；Longitudinally disposed gas condensed water inlet pipe and longitudinally disposed water is filled in transverse pipe
The bottom of chamber, the gas condensed water inlet pipe and water cavity communicates with transverse pipe, and the water cavity bottom sets discharge outlet, discharge outlet with
Overflow water channel is communicated, and the flap of closing discharge outlet is set in discharge outlet, and flap is connected by swing rod with ball float；On water cavity wall
Liquid level gauge is set.
The utility model is rational in infrastructure, good working effect；It is fully achieved and " does not have water-stop, there is water draining, few water is arranged less, many
Water is multiple rows of " functional requirement, preferably resolve gas-pipe line, gas fittings（Valve etc.）The drainage problem of ponding, it is suitable extensively
For the safety drain of coal gas high-low pressure occasion.With original " water trap（Drainage seal tank）Or the water trap with device for preventing leakage "
Compare, there is more safe and efficient draining, sealed reliable, easy to maintenance.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the cross-sectional view of Fig. 1.
Specific embodiment
A kind of coal gas draining valve, including base 1, fill transverse pipe 2 on base, one end of transverse pipe is closed, and the other end is row
Dirty mouth 3, sewage draining exit is provided with door；Longitudinally disposed gas condensed water inlet pipe 4 and longitudinally disposed water cavity 5 is filled in transverse pipe,
The bottom of the gas condensed water inlet pipe and water cavity communicates with transverse pipe, and the water cavity bottom sets discharge outlet 6, discharge outlet with overflow
Flowing flux 7 is communicated, and the flap 8 of closing discharge outlet is set in discharge outlet, and flap is connected by swing rod 9 with ball float 10；In water cavity
Liquid level gauge 11 is set on wall.
When draining valve has ponding（The equipment such as gas-pipe line, valve have ponding）, when draining valve internal water accumulation does not arrive certain position,
Still in sealing state；When ponding exceeds certain position, draining valve seal is automatically turned on and draining；When water level is less than the position
When, valve is automatically switched off and seals.
This draining valve can continuous drainage, can intermittent drainage, sealed reliable when anhydrous, safety drain when having water, pipeline coal gas
Pressure oscillation works without influence this draining valve.
