Abstract
The utility model discloses a steam drum water level low declination mica water level gage which is a measuring device of boiler steam drum water level belonging to a boiler assorted device. The steam drum water level low declination mica water level gage is characterized in that the upper part of the surface relative to two water communication pipes are respectively added with a condensing pot. As the condensing pot can cool the saturated steam, complement and heat the water in the water communication pipes in time, the temperature of the water in the water communication pipes approximates to the temperature of the water in the steam drum and the water level of the steam drum can be accurately reflected. The water in the water communication pipes can flow back to the steam drum through a water side sampling pipe to increase the flowability of the water and obtain the effect of heat transfer and self pollution discharge. The mica can be kept clean and transparent and the lifetime of the mica can be prolonged.
Description
Technical field:
The utility model relates to a kind of steam water-level low deviation mica water level meter, is the measurement mechanism of boiler drum level.Belong to the boiler auxiliary products.
Background technology:
Existing steam water-level low deviation mica water level meter (is seen Fig. 1, Fig. 2), its structure is the water communicating pipe 11 that interconnects in the processing of the left and right sides, inside of table body 4, the centre of water communicating pipe 11 and both sides three vapour communicating pipes 23 of reprocessing, the bottom of water communicating pipe 11 is connected with water valve 13 by water pipe 24, top is connected to steam valve 1, be connected to balance pipe 9 between steam valve 1 and the water valve 13, steam valve 1 passes on left vapour side probe tube 2 and is connected with drum 12, water valve 13 passes on left lateral water sampling tube 8 and is connected with drum 12, the bottom of water valve 13 is connected with blow-off pipe 10, vapour communicating pipe 23 connects drainpipe 25 by steam pipe 22, drainpipe 25 is connected to down-comer 26, and five tappings in the both sides, front and back of water communicating pipe 11 are pressed on mica sheet 7 on water communicating pipe 11 with foundary weight 5 respectively and (specifically illustrate as Fig. 2); As shown in Figure 2, with foundary weight 5 mica sheet 7, Graphite pad 21 and auxiliary glass 17 are pressed on the table body 4, with stud 16 and nut 6 foundary weight 5 and table body 4 are linked together, the light that columnar lamp 14 sends is by being fixed on the water communicating pipe 11 on red glass 18, green glass 19 and the refracting glass 20 exposure chart bodies 4 on the glass seat 15 and since in water communicating pipes 11 the refractive index difference of water, vapour to make that opposite side at table body 4 can observe light green vapour red.The water of doing although it is so in his-and-hers watches body 4 well and the table body 4 heat, reach the purpose that the water temperature that makes table body 4 approaches the water temperature in the drum 12, but its shortcoming is the additional untimely of water in water communicating pipe 11, mobile little, water level reduces to cause temperature to reduce just, blowdown is untimely, and mica sheet 7 is very easily fuzzy, observes unclear; Because the heat of balance pipe 9 distributes, cause near the water level in the communicating pipe 11 of balance pipe 9 one side water will be higher than away from the water level in the water communicating pipe 11 of balance pipe 9 one sides, cause measurement inaccurate.
The content of utility model:
In order to overcome the shortcoming of original technology, the purpose of this utility model provides a kind of steam water-level low deviation mica water level meter that the drainer that has the tubule that inserts water communicating pipe is installed on position relative with water communicating pipe above the table body.
The purpose of this utility model is achieved through the following technical solutions, a kind of steam water-level low deviation mica water level meter, by table body 4, water communicating pipe 11, steam valve 1, water valve 13, vapour side probe tube 2, lateral water sampling tube 8, vapour communicating pipe 23, light-source box 3 is formed, it is characterized in that on position relative above the table body 4 welding respectively has the left drainer 27 and the right drainer 28 of the tubule 29 that inserts water communicating pipe 11 with two water communicating pipes 11, the tube wall welding of one end of tubule 29 and left drainer 27 and right drainer 28, the other end inserted in water communicating pipe 11, and the left drainer 27 of close balance pipe 9 one sides is than right drainer 28 wall thickness 1-5mm.
Advantage of the present utility model:
1, owing to above the table body 4 relative, increased left drainer 27 and right drainer 28 with water communicating pipe 11, meeting condensation after saturated vapor enters left drainer 27 and right drainer 28 forms saturation water and is flow to downwards in water communicating pipe 11 by tubule 29, in time replenish and add water in hot water communicating pipe 11, make water temperature in water communicating pipe 11 more near the water temperature in the drum 12, can accurately reflect the water level in the drum 12, and the water in water communicating pipe 11 can be back to drum 12 by lateral water sampling tube 8, increase the flowability of water, reach heat exchange and from filth-discharging effect, it is transparent that mica sheet is kept clean, and reduces on-the-spot blowdown number of times.
2, because left drainer 27 and right drainer 28 have increased the complementary capabilities to the water in water communicating pipe 11, it is little to make that water in water communicating pipe 11, stripping temperature change, reduce the thermal stress of table body and foundary weight, the slip of table body is descended greatly, guaranteed the reliability service of water level meter.
3, because near the wall thickness of the left drainer 27 of balance pipe 9 one sides wall thickness greater than right drainer 28, the condensation effect of right drainer 28 is better than the condensation effect of left drainer 27, to more away from water communicating pipes 11 moisturizing of balance pipe 9 one sides, it is better to add thermal effect, so just can balance both sides water communicating pipe 11, make it reach the water level unanimity.
