Description
Technical Field
The utility model relates to a rail engineering car technical field specifically is a desicator fault isolation device.
Background
At present, in order to ensure that wind output by a wind source system is cleaner and drier, a drier is required to be arranged on a railway vehicle, and the drier is a device for removing impurities such as water, oil, dust and the like in compressed air. The device can prevent the railway vehicle braking system from generating the phenomena of corrosion, blockage, condensed water, icing and the like, can avoid the driving accidents caused by the brake failure caused by the phenomena, and can prolong the maintenance period of the brake.
The prior railway vehicle is generally characterized in that an air compressor is directly connected with a dryer through a pipeline and used for processing compressed air output by the air compressor. If the desicator breaks down, when unable normal start-up work, the measure of generally taking is that the desicator switch is turned off, then pulls down the maintenance, and rail vehicle can't use this moment, seriously influences work efficiency.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to overcome current defect, provide a desicator fault isolation device, can not influence the dry cleanness of whole car wind regime system when the desicator breaks down, guarantee the machineshop car normal operating, can effectively solve the problem in the background art.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a desicator fault isolation device, includes the desicator, be provided with first cock between desicator and the air compressor machine, the other end of desicator is provided with the second cock, be connected with the protection pipeline between air compressor machine and the first cock, be provided with third cock and oil water separator on the protection pipeline, the one end of protection pipeline is linked together through pipeline and the pipeline that is provided with the second cock.
As a preferred technical scheme of the utility model, first cock and second cock are the cock that leads to always, the third cock is the normal close cock.
As an optimized technical scheme of the utility model, still be provided with the dirt check valve of straining on the protection pipeline, the dirt check valve setting is in oil water separator's rear end.
As an optimized technical scheme of the utility model, the both ends of protection pipeline are can dismantle with the intercommunication department that corresponds the pipeline and be connected.
Compared with the prior art, the beneficial effects of the utility model are that: (1) The first plug door and the second plug door are additionally arranged at the front and the rear of the dryer respectively, when the dryer fails, the plug doors at the front and the rear of the dryer can be closed, and then the dryer is detached for maintenance, and the whole vehicle air source system cannot be influenced; (2) A protection pipeline is connected in parallel in the gas circuit, a third plug valve is arranged on the protection pipeline, when the dryer is normal, the third plug valve is in a closed state, the normal function of the dryer cannot be influenced, and when the dryer fails, the third plug valve can be opened; (3) The oil-water separator and the dust filtering check valve are arranged on the protection pipeline, the oil-water separator plays a role in drying compressed air, the dust filtering check valve can filter dust and prevent filtered air from flowing backwards, the oil-water separator and the dust filtering check valve play the same functions as the dryer, and the cost is low; (4) The protection pipeline is connected in parallel at the dryer, so that when the dryer is dismounted for maintenance, compressed air can achieve the effects of filtering and drying when passing through the protection pipeline, and the use of a vehicle is not influenced.
Drawings
FIG. 1 is a schematic view of the present invention during normal operation;
fig. 2 is a schematic diagram of the present invention in a fault state.
In the figure: the device comprises a first cock 1, a dryer 2, a second cock 3, a dust filtering check valve 4, an oil-water separator 5, a third cock 6 and a protection pipeline 7.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a desicator fault isolation device, including desicator 2, be provided with first cock 1 between desicator 2 and the air compressor machine, the other end of desicator 2 is provided with second cock 3, be connected with protection pipeline 7 between air compressor machine and the first cock 1, be provided with third cock 6 and oil water separator 5 on the protection pipeline 7, first cock 1 and second cock 3 are the cock that leads to always, third cock 6 is the normally closed cock, still be provided with the dirt check valve 4 on the protection pipeline 7, the dirt check valve 4 sets up the rear end at oil water separator 5, the one end of protection pipeline 7 is linked together through pipeline and the pipeline that is provided with second cock 3, the both ends of protection pipeline 7 and the intercommunication department that corresponds the pipeline are can be dismantled and be connected, be convenient for this device can dismantle and install at any time, this desicator fault isolation device compact structure, and reasonable design, and convenient operation, can not influence the normal use of machineshop when the desicator breaks down, guarantee the drying of wind regime, be favorable to guarantee neatly simultaneously, the work process, the convenience in use nature is greatly improved.
When the dryer is in a normal function, compressed air sequentially passes through the first cock 1, the dryer 2 and the second cock 3, wherein the first cock 1 and the second cock 3 are in a normally open state, namely the compressed air can pass through the first cock 1 and the second cock 3; when 2 troubles of desicator, close first cock 1 and second cock 3 around 2 desicators, compressed air can not pass through desicator 2 this moment, desicator 2 is kept apart promptly, open the third cock 6 on the protection pipeline 7 simultaneously, compressed air can pass through third cock 6, oil water separator 5 and dirt filtering check valve 4, oil water separator 5 plays dry compressed air's effect, dirt filtering check valve 4 not only can strain the dirt, can also prevent the air after the filtration against the current.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
