Wherein: 1, housing, 2, inlet flange, 3, outlet pipe, 4, retain baffle plate, 5, condensation water channel, 6, floating drum, 7, warning indicating arm, 8, fixing rod, 9, first connecting rod, 10, second connecting rod, 11, third connecting rod, 12, axle ear, 13, seal ring, 14, sealing seat, 15, blowdown valve.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to protection domain of the present utility model.
As depicted in figs. 1 and 2, a kind of coal gas drainer automatic drain valve with instruction of reporting to the police of the present utility model, comprise housing 1, side, housing 1 top is provided with inlet flange 2, inlet flange 2 runs in hydrophone flow-off, housing 1 top opposite side is provided with outlet pipe 3, in housing 1, welding one retains baffle plate 4, this retains baffle plate 4 and housing 1 is divided into upper and lower two spaces, retain the condensation water channel 5 baffle plate 4 being processed with band sealing, condensed water is discharged by this passage, retain in the housing 1 above baffle plate 4 and floating drum 6 is set, retain bottom baffle plate 4 and linkage mechanism is set, linkage mechanism one end connects floating drum 6, the linkage mechanism the other end connects warning indicating arm 7, warning indicating arm 7 is installed in outlet pipe 3.
Linkage mechanism is set, for the ease of controlling rising or the decline of warning indicating arm 7, linkage mechanism comprises fixing rod 8, first connecting rod 9, second connecting rod 10 and third connecting rod 11, fixing rod 8 upper end connects bottom floating drum 6, hinged first connecting rod 9 one end, fixing rod 8 lower end, first connecting rod 9 the other end hinged second connecting rod 10 one end, second connecting rod 10 the other end hinged third connecting rod 11 one end, the hinged warning indicating arm 7 of third connecting rod 11 the other end.
Wherein, be fixed on by axle ear 12 in the middle part of first connecting rod 9 and retain bottom baffle plate 4.First connecting rod 9 is by bearing pin with the Placement of axle ear 12, makes first connecting rod 9 have the individual strong point.
When the water yield is few, in order to make floating drum 6 keep sealing in decline process, with seal ring 13 bottom floating drum 6, the condensation water channel 5 retaining baffle plate 4 is provided with the sealing seat 14 mated with seal ring 13.
In side, housing 1 bottom, blowdown valve 15 is installed, is convenient to blowdown, extend the drain valve life-span.
Working procedure of the present utility model:
With reference to figure 1, after being full of water in housing 1, floating drum 6 floats by the effect of buoyancy, and drive warning indicating arm 7 to stretch out outlet pipe 3 mouthfuls by linkage mechanism, now drainage channel is opened, and condensed water can from outlet pipe 3 mouthfuls discharge.
With reference to figure 2, when deficient water appears in housing 1, the water level in automatic drain valve declines gradually, and the buoyancy of floating drum 6 reduces gradually, and now, floating drum 6 closes drainage channel gradually.When height of water level is not enough to overcome gas pressure, water seal and breakdown, coal gas goes out hydathode, floating drum 6 is pressed on sealing surface (seal ring 13 referred to bottom floating drum 6 seals with condensation water channel 5 upper seal support 14) tightly under the effect of gas pressure, prevent the leakage of coal gas, driven by linkage mechanism with alarm indicating arm 7, fall in water outlet.
Drain valve of the present utility model is directly contained in normal discharge device flow-off, is therefore easy to normal discharge device to be transformed into leakage-proof type hydathode.
Automatic drain valve of the present utility model, closed structure, prevents moisture from evaporating; Band warning indicating arm display working condition; Simple to operate, use, easy to maintenance; Safely, reliably, automaticity is high, has water draining, anhydrous closedown, gas leakage preventing.
