Description
Technical field
The utility model relates to a kind of ducted device in systems such as gas discharge in mine system and ground gas utilization system and coal bed gas conveyings, the automatic tailrace of gas pipeline specifically.
Background technology
In systems such as gas discharge in mine system and ground gas utilization system and coal bed gas conveying, when nearer, generally use solenoid control to discharge water apart from supply terminals; When far away, generally adopt the draining of artificial fixed cycle operator valve; The electromagnetic valve draining is easy to generate corrosion and causes the spool jam, and the electric fault rate is higher; The draining of manually-operated valve, operation often, valve is fragile, when human factor does not discharge water when pipeline is catchmented, will cause a large amount of band water in the Device in Gas course of conveying, the undesired even disconnected combustion of combustion apparatus burning, igniting are not smoothly or can't normal ignition.
Summary of the invention
In order to overcome the deficiency of prior art, and provide a kind of simple in structure, be easy to safeguard the automatic tailrace of safe and reliable gas pipeline.
The utility model is to realize like this; The automatic tailrace of gas pipeline; Mainly be made up of water inlet pipe, Water collecting tube, float, lever, draining valve, it is characterized in that: an end of described Water collecting tube bottom is provided with the valve body of draining valve, and valve rod, stem guiding plate are installed in the described valve body in order; The bottom of described stem guiding plate and valve body fixes, and the outside low side of valve body is provided with fixed valve base; Described valve rod passes fixed valve base and is connected with rubber spool, spool disk, clamp nut in order; The other end of described valve rod and valve rod junction plate are hinged, and described lever one end and valve rod junction plate are hinged, and the other end and float fix; The other end of described Water collecting tube passes through bolt seals by flange and blind plate; Described water inlet pipe is arranged on the top of Water collecting tube.
Device in Gas is in course of conveying; The aqueous water of some is brought in the pipeline, and after temperature in the running descended, the moisture content condensation was deposited on the methane gas below; Flow forward along duct bottom; When arriving the tailrace water inlet pipe mouth, the valve on the water inlet pipe is the enable possition at this moment, and water flows into Water collecting tube through valve.According to situation such as the ratio of gas band water and pipeline distances, several tailraces of installing in pipeline, collect respectively with each section of regular discharge pipeline on catchmenting, make methane gas resistance in course of conveying minimum, carry the section maximum.
Automatically tailrace is according to buoyancy of water and mechanical lever principle, is fulcrum with the support arm, buoyancy of water is converted into the mechanical slide force of lever; Make spool do relative motion along the valve rod center line; Control the switching of draining valve: should the water in the Water collecting tube be drained, guarantee that again discharging valve in time cuts out, avoid methane gas to external leakage; Thereby the gas conveyance conduit is worked under anhydrous relatively condition; Maximally utilise the line transportation section and reduce flow resistance, improve transfer efficiency, guarantee the delivery safety of methane gas and the normal operation of follow-up gas equipment.
Therefore the utlity model has simple in structurely, be easy to safeguard safe and reliable advantage.

Fig. 1 is the structural representation of the utility model
Fig. 2 is the lateral view of the utility model
The specific embodiment
Below in conjunction with description of drawings, the utility model is done further elaboration.
The automatic tailrace of aforesaid gas pipeline; Mainly form by water inlet pipe 1, Water collecting tube 2, float 3, lever 11, draining valve; It is characterized in that: an end of described Water collecting tube 2 bottoms is provided with the valve body 5 of draining valve, and valve rod 4, stem guiding plate 13 are installed in the described valve body 5 in order; Described stem guiding plate 13 fixes with the bottom of valve body 5, and the external bottom end of valve body 5 is provided with fixed valve base 9; Described valve rod 4 passes fixed valve base 9 and is connected with rubber spool 8, spool disk 7, clamp nut 6 in order; The other end of described valve rod 4 and valve rod junction plate 10 are hinged; Described lever 11 1 ends and valve rod junction plate 10 are hinged, and the other end and float 3 fix; The other end of described Water collecting tube 2 is sealed through bolt 17 by flange 16 and blind plate 18; Described water inlet pipe 1 is arranged on the top of Water collecting tube 2.
Automatically tailrace is installed in the more low-lying location in the gas pipeline, uses slip-on welding flange, and elbow bend is connected with gas tube through valve, when current flow to water inlet along the gas throughput direction, stores in the Water collecting tube through inlet valve entering tailrace.Its manner of execution is following:
1, relative static conditions
When design; Float 3 lower ends and dust-collecting bucket 2 bottoms keep static relatively equilibrium state; Float 3 forms one to the moment that presses down on lever, because the effect of lever support arm 12 fulcrums, the other end of lever 11 produces a pulling force that makes progress; Drive valve rod 11 with upwards tension of rubber spool 8, sealing through valve rod junction plate 10, make water level keep motionless.
2, catchment and the draining course of action
Water in pipeline constantly flows into Water collecting tube 2, and the buoyancy of float 3 constantly increases, if this moment, water level continued to rise; When buoyancy of water is enough to overcome the pressure of float 3 and lever 11 and when float 3 is moved up; Pull lever 11 is upwards operation simultaneously, is fulcrum with lever support arm 12, and the other end of lever 11 produces downward pressure simultaneously; Promote valve rod 4 and move down with rubber spool 8, draining begins; When the water in the Water collecting tube 2 was disposed to design water height, float 3 descended, and pulling valve rod 4 makes progress, rubber spool 8 and fixed valve base 9 closures, and draining ends.
3, circulation
After draining circulation finished, water level, float 3, lever 11, valve rod 4, rubber spool 8 all kept the relative static conditions of temporarily sealing, if this moment the anhydrous Water collecting tube 2 that flows into, this standstill seal state is kept continuing; If continue water inlet in the Water collecting tube 2, water level continues to rise, and breaks the relative equilibrium of original standstill seal, carries out per two drainage procedures.Reciprocation cycle like this is all without manually-operated.The operating principle and the working method of Here it is the automatic tailrace of gas pipeline.
