Technical field
The utility model relates to the ammonia refrigeration system field, particularly a kind of pollution discharge type ammonia liquid reservoir level instruction device.
Background technology
In ammonia refrigeration system, existing ammonia fluid reservoir is installed an easy liquid level charactron (glass tube) through communicating pipe usually, and is so that the operating personnel can observe the level condition of the ammoniacal liquor in the fluid reservoir at any time, as shown in Figure 1.Owing in whole ammonia refrigeration system, be mixed with refrigeration oil, though after filtering through the wick of oil content, oil cooling and condenser, still residual in the ammoniacal liquor have a spot of refrigeration oil; Therefore in the low temperature fluid reservoir, the ammoniacal liquor surface can form one deck oil film, and liquid level charactron causes liquid level fuzzy owing to freeze the oil alluvial; Low visibility; Can not react the level condition of ammoniacal liquor in fluid reservoir timely and effectively, have a strong impact on the operating personnel and observe the ammoniacal liquor position in the fluid reservoir, form potential safety hazard; And liquid level charactron is behind glass tube alluvial refrigeration oil, and it is bigger that greasy dirt is got rid of difficulty, very inconvenient.
Summary of the invention
The utility model technical matters to be solved provides a kind of pollution discharge type ammonia liquid reservoir level instruction device; Can prevent that the liquid level that causes because of the refrigeration oil alluvial is fuzzy; Phenomenons such as low visibility; Increase the visibility of liquid level, help the convenient working personnel and observe the ammoniacal liquor in the liquid reservoir constantly, further can also have the function of automatic warning.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of pollution discharge type ammonia liquid reservoir level instruction device, comprise fluid reservoir, and fluid reservoir is communicated with communicating pipe at two ends up and down; Be provided with liquid level charactron in the middle part of communicating pipe; Communicating pipe, two ends were provided with first stop valve and second stop valve, also were provided with blow-off pipe in the position near the liquid level charactron lower end, and blow-off pipe is provided with the 5th stop valve.
Also be provided with the parallel transistor parallelly connected with liquid level charactron, parallel transistor is provided with electromagnetism floating ball lever meter and following electromagnetism floating ball lever meter.
Also be provided with the 3rd stop valve and the 4th stop valve at the liquid level charactron two ends, blow-off pipe is between second stop valve and the 4th stop valve.
A kind of pollution discharge type ammonia liquid reservoir level instruction device that the utility model provides; Through the blow-off pipe that is provided with; Can at any time the ammoniacal liquor in the liquid level charactron be discharged, thereby prevent that the liquid level that causes because of the refrigeration oil alluvial is fuzzy, phenomenons such as low visibility; Increase the visibility of liquid level, help the convenient working personnel and observe the ammoniacal liquor in the fluid reservoir constantly; Simultaneously, the electromagnetism floating ball lever meter of setting has the function that the high and low limit liquid level of the ammoniacal liquor in the ammonia fluid reservoir is reported to the police automatically.The utility model has ensured the safe operation of ammonia fluid reservoir effectively, has improved ammonia refrigeration process safe property.Simple in structure, easy to make, long service life, and energy-conserving and environment-protective, construction are convenient, effectively reliable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the prior art constructions synoptic diagram.
Fig. 2 is the one-piece construction synoptic diagram of the utility model.
Among the figure: communicating pipe 1, the first stop valve 2, liquid level charactron 3, the second stop valves 4, drain pipe 5; Feed tube 6, fluid reservoir 7, parallel transistor 8, blow-off pipe 9, the five stop valves 10; The 3rd stop valve 11, last electromagnetism floating ball lever meter 12, following electromagnetism floating ball lever meter 13, the four stop valves 14.
Embodiment
In Fig. 2; A kind of pollution discharge type ammonia liquid reservoir level instruction device comprises fluid reservoir 7, and fluid reservoir is communicated with communicating pipe 1 at two ends about in the of 7; Communicating pipe 1, the middle part was provided with liquid level charactron 3; Communicating pipe 1, two ends were provided with first stop valve 2 and second stop valve 4, also were provided with blow-off pipe 9 in the position near liquid level charactron 3 lower ends, and blow-off pipe 9 is provided with the 5th stop valve 10.Described communicating pipe 1 adopts the steel pipe of diameter 25mm to process, and liquid level charactron 3 is the glass tube of diameter 25mm.The general flexible plastic tube that adopts with the footpath of blow-off pipe 9 afterbodys, and be embedded in the water, leak in the air to prevent ammonia.
Structure thus; Can get rid of liquid level charactron 3 and the ammoniacal liquor that contains refrigeration oil in communicating pipe 1 at any time, to keep the sharpness of liquid level charactron 3, method of operating is following: before the discharging; Earlier first stop valve 2 and second stop valve 4 are closed; Open the ammoniacal liquor that 10 dischargings of the 5th stop valve are mixed with refrigeration oil then, close the 5th stop valve 10 after discharging finishes, again first stop valve 2 and second stop valve 4 are opened and can be returned to normal production at last.
In the scheme of optimizing, also be provided with the parallel transistor 8 parallelly connected with liquid level charactron 3, parallel transistor 8 is provided with electromagnetism floating ball lever meter 12 and following electromagnetism floating ball lever meter 13.Structure thus: when the ammoniacal liquor liquid level in the ammonia fluid reservoir 7 reaches this high and low position of limit, last electromagnetism floating ball lever meter 12 or down 13 of electromagnetism floating ball lever meters give the alarm automatically, remind the operating personnel to take appropriate measures; Simultaneously, can also introduce in the warning horn in the office, be used for managerial personnel's early warning to the distant place at connection line on last electromagnetism floating ball lever meter 12 and the following electromagnetism floating ball lever meter 13.
