Determine part.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than it is all real
Apply example.Based on the embodiment in the utility model, those of ordinary skill in the art under the premise of creative work is not made, institute
The every other embodiment for obtaining, belongs to the utility model protection domain.
In order that those skilled in the art more fully understand the utility model scheme, below in conjunction with the accompanying drawings and it is embodied as
The utility model is described in further detail for mode.
Fig. 1 is refer to, Fig. 1 is structure of pressure relief device schematic diagram provided by the utility model.
A kind of pressure relief device provided by the utility model, it is including cylinder 1, affixed at the top of the cylinder 1 to be provided with close
Capping plate 2,1 bottom of the cylinder are provided with shrouding 3, and the shrouding 3 is provided with through hole, and affixed connection on the through hole outer wall is provided with
With the connection short tube 4 of high voltage relief pipeline connection, the diameter of section of the cylinder 1 is more than the diameter of section for connecting short tube 4.
Wherein, when pressure release is needed, just can be by connection short tube 4 and high voltage relief pipeline connection, in order to ensure the effect of pressure release
Fruit and avoid compressed air to connect short tube 4 cause damage, preferably connect short tube 4 section directly with the high voltage relief pipe
The section on road is directly equal.
In the course of the work, when pressure release is needed, first by connecting short tube 4 and high voltage relief pipeline, then start to let out
Pressure, compressed air are entered in cylinder 1 by connecting short tube 4, because the diameter of section of cylinder 1 is more than the section of connection short tube 4
Diameter, therefore after compressed air is entered in cylinder 1, moment increases the contact area of compressed air and air, so as to drop indirectly
The low intensity of pressure, this just effectively reduces the pressure of compressed air abrupt release, and then slows down compressed air to system pipes
The damage of reason and equipment.
For the ease of connecting the connection between short tube 4 and high voltage relief pipeline, 4 bottom of the preferred connection short tube is also solid
It is equipped with adpting flange 5.By adpting flange 5 and high voltage relief pipeline connection, be so not only convenient for installing, and be also convenient for it is right
The dismounting of connection short tube 4.
Certainly, it will be appreciated by persons skilled in the art that when compressed air is entered in cylinder 1 by connecting short tube 4
When, and when expanding with air contact moment in the cylinder 1, all can produce certain impact to cylinder 1, so as to when cylinder 1 produce
Life is rocked or is deformed, therefore, it is in order to preferably resist the impulsive force, preferably also affixed at the top of seal cover board 2 to set
Put mounting fixing parts 6.Can be produced with extraneous any device or setting by mounting fixing parts 6 and be connected, cylinder 1 is obtained more preferably
Fixed support, it is to avoid produce when by impulsive force and rock or deform.
In one specific embodiment of the utility model, the seal cover board 2 is sealing flange, the sealing flange and institute
State 1 welded top of cylinder.And preferably described mounting fixing parts 6 are dismantled and assembled flange, and the dismantled and assembled flange is close with described
Envelope flange welding.Flange is the connection member connected between common pipeline in daily life, and the middle part of sealing flange is not
Penetrating, therefore effectively can realize to the sealing at the top of cylinder 1, and flange also has convenience of drawing materials, and it is easy to process
Advantage.
In order to further optimize the various embodiments described above, also including pressure detection means, the pressure detection means include setting
The pressure probe being placed in inside the cylinder 1 and the pressure value table being arranged on 1 outer wall of the cylinder.Those skilled in the art
Although it is understood that product can realize the pressure abrupt release to compressed air, can not learn after discharging pressure
Air also have great pressure values, therefore by arrange pressure detection means obviously can see release after air
Also retain great pressure, and then learn whether display release is safe.In the course of the work, in cylinder 1 pressure probe can when
The pressure change in detection cylinder 1 is carved, and transmits a signal to pressure value table, corresponding correspondence is shown by pressure value table
Pressure, to observe to the pressure in which.
Further, also including warning device, the warning device is connected with pressure probe.Pressure in cylinder 1
When still exceeding predetermined pressure by force, warning device automatically begins to report to the police, and reminds the pressure in current cylinder 1 too high.
Certainly, warning device has diversified, can be such as disposed on 1 outer wall of cylinder alarm lamp, works as cylinder
After pressure in body 1 exceedes predetermined value, alarm lamp starts flicker；Siren can also be made, when when the pressure in cylinder 1 is more than predetermined
After value, siren begins to send out the sound.
It should be noted that alarm lamp can also be arranged with siren simultaneously, and can also be operated simultaneously.
Pressure relief device provided by the utility model, including cylinder 1, is provided with seal cover board 2, cylinder 1 at the top of cylinder 1
Bottom is provided with shrouding 3, is additionally provided with through hole, and through hole outer wall also affixed being provided with and connects short tube 4, finally by connection on shrouding 3
Short tube 4 and high voltage relief pipeline connection, and the diameter of section of cylinder 1 is more than the diameter of section of connection short tube 4.In the course of work
In, when pressure release is needed, first by connecting short tube 4 and high voltage relief pipeline, then starting pressure release, compressed air is by connection
Short tube 4 is entered in cylinder 1, because the diameter of section of cylinder 1 enters more than the diameter of section of connection short tube 4, therefore compressed air
After entering in cylinder 1, moment increases the contact area of compressed air and air, and so as to reduce indirectly the intensity of pressure, this just has
The pressure for reducing compressed air abrupt release of effect, and then slow down damage of the compressed air to system administration and equipment.
Above pressure relief device provided by the utility model is described in detail.It is used herein specifically individual
Example is set forth to principle of the present utility model and embodiment, and the explanation of above example is only intended to help and understands this reality
With new method and its core concept.It should be pointed out that for those skilled in the art, without departing from this
On the premise of utility model principle, some improvement and modification can also be carried out to the utility model, these improve and modification also falls
Enter in the utility model scope of the claims.
