Abstract
And a pneumatic valve connecting pipeline of a hydrogen drier of the hydrogen-cooled generator set. The dryer body has the functions of moisture absorption, heating and regeneration, and the circulation process is completely finished by setting and switching the pneumatic valve, and the pneumatic valve plays a leading role; the key point is to ensure the safe and normal switching of the pneumatic valve. The utility model comprises the following components: connecting tube (3) and cover the outside warning cover (4) of connecting tube, the warning cover be the integral type structure of constituteing by a plurality of straight tubes (8) and a plurality of soft cover (9), the straight tube with soft cover interval arrangement, every the straight tube on all be fixed with a whistle (7). The connecting pipeline is used for the pneumatic valve connecting pipeline of the hydrogen drier of the hydrogen-cooled generator set.
Description
Technical Field
The utility model relates to a pneumatic valve connecting pipeline of a hydrogen drier of a hydrogen-cooled generator set.
Background
Modern power generation enterprises attach high importance to the safe and economic operation of the generator set, and the requirements on humidity maintenance and hydrogen purity in the hydrogen-cooled generator are particularly important; the drying in the generator is kept, so that the insulation strength of the stator and rotor windings is not influenced, the generator is protected from the increase of ventilation friction loss caused by overhigh humidity and reduced hydrogen purity, and the safe and stable operation of the unit is influenced; in the daily operation of the hydrogen dryer, the dryer body has the functions of moisture absorption, heating and regeneration, and the cycle process is completely finished by setting and switching the pneumatic valve, so that the pneumatic valve plays a leading role; the key point is to ensure the safe and normal switching of the pneumatic valve.
Disclosure of Invention
The utility model aims to provide a pneumatic valve connecting pipeline of a hydrogen drier of a hydrogen-cooled generator set.
The above purpose is realized by the following technical scheme:
the utility model provides a hydrogen-cooled generating set hydrogen desicator pneumatic valve connecting line, its constitution includes coupling hose and cover the outside warning cover of coupling hose, the warning cover be the integral type structure of constituteing by a plurality of straight tubes and a plurality of soft cover, the straight tube with soft cover interval arrangement, every the straight tube on all be fixed with a whistle.
The hydrogen-cooled generator set hydrogen dryer pneumatic valve connecting pipeline, the soft sleeve of the alarm sleeve is bound with a binding belt and tightly tied with the connecting hose.
Has the advantages that:
1. according to the utility model, the alarm sleeve is sleeved outside the connecting hose, so that the alarm sleeve can play a role in protecting the connecting hose, and meanwhile, when the connecting hose is broken and leaks air or when a connector leaks air, the air leakage can be discharged from each straight pipe through the whistle on each straight pipe, so that the whistle can make a sound to play an alarm role, and the phenomenon of air leakage can be found in time.
Description of the drawings:
FIG. 1 is a front view of the present invention;
FIG. 2 is a schematic structural view of the present invention;
in the figure: 1. a dryer; 2. a joint; 3. a connecting hose; 4. an alarm sleeve; 5. a pneumatic valve; 6. a threaded sleeve; 7. a whistle; 8. a straight pipe; 9. a soft sleeve; 10. and (6) binding the belt.
The specific implementation mode is as follows:
example 1:
the utility model provides a hydrogen-cooled generating set hydrogen desicator pneumatic valve connecting line, its constitution includes coupling hose 3 and cover the outside warning cover 4 of coupling hose, the warning cover be the integral type structure of compriseing a plurality of straight tubes 8 and a plurality of soft cover 9, the straight tube with soft cover interval arrangement, every the straight tube on all be fixed with a whistle 7.
Example 2:
according to the pneumatic valve connecting pipeline of the hydrogen drier of the hydrogen cooling generator set in the embodiment 1, the soft sleeve of the alarm sleeve is bound with the binding belt 10 and tightly tied with the connecting hose.
The working principle is as follows: the swivel nut 6 is fixed at the joint part where the dryer 1 and the pneumatic valve 5 are connected, the alarm sleeve is sleeved on the connecting hose, the connecting hose is fixed with the joint 2, then the two ends of the alarm sleeve are in threaded connection with the swivel nut, and finally the binding belt is bound at each soft sleeve to be tightly bound, so that each straight pipe forms an independent gas leakage space, when the connecting hose and the joint leak, leaked gas can flow into the straight pipe from the connecting hose, sound is formed by blowing out a gas whistle from the straight pipe, and workers can find the gas in time.
Claims (2)
1. The utility model provides a hydrogen-cooled generating set hydrogen desicator pneumatic valve connecting line, characterized by: the alarm sleeve is an integrated structure consisting of a plurality of straight pipes and a plurality of soft sleeves, the straight pipes and the soft sleeves are arranged at intervals, and each straight pipe is fixed with a whistle.
2. A hydrogen-cooled generator set hydrogen dryer pneumatic valve connecting line as claimed in claim 1, characterized by: the soft sleeve of the alarm sleeve is bound with a binding belt and tightly tied with the connecting hose.
