Description
Technical field
The utility model belongs to back-fire relief security technology area, and in particular to one kind is novel to use fire arrester coldly.
Background technique
Fire arrester is the safety device for preventing the propagation of flame of inflammable gas and flammable liquid steam.It is typically mounted at
It conveys in flammable, inflammable gas pipeline, or in the groove tank of ventilation, the device for preventing propagating flame from passing through.
Currently, the fire arrester used in oil storage tank, usually arranges in pairs or groups with breather valve and uses.The resistance that cold district uses
Firearm forms water droplet since vapor is attached on back-fire relief disk, and to form blocking, this is breakneck for condensation.
Utility model content
To solve the above problems, the utility model provides a kind of coldly with fire arrester, the inclination for passing through special setting hinders
Fiery disk can effectively prevent freezing, and solve current cold district using vapor in fire arrester when fire arrester and freeze blocking
Problem.
It is a kind of to use fire arrester, including clack box shell and back-fire relief disk coldly.The clack box shell is that both ends are small broad in the middle
Spindle structure, the clack box shell includes inlet side and outlet；The inlet side of the clack box shell and the outer surface of outlet are equipped with
Flange；The outwardly projecting groove different there are two opposite height is set in the middle part of the clack box shell；The clack box shell
Inside is equipped with inclined back-fire relief disk, and the inner wall of the groove is tightly attached at the both ends of the back-fire relief disk respectively；In described two grooves
The outer wall of the lower groove in position is equipped with drainage hole, the external drainage pipeline of drainage hole.
Further, the back-fire relief disk includes the dictyosome at multiple interval；The dictyosome includes made of metal core material and fluorine resin
Layer.
Further, the outer wall of the higher groove in position is equipped with opening in described two grooves, sets in the opening
There is sealing cover, for safeguarding, replacing, maintaining the back-fire relief disk.
Further, higher one end of the back-fire relief disk is equipped with handle, for being put into or taking out back-fire relief disk.
Further, the tilt angle of the back-fire relief disk is 5 to 10 degree.
Compared with prior art, the utility model has the beneficial effects that the utility model structure is simple, maintenance is convenient, antifreeze
Significant effect.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram for using fire arrester coldly provided by the utility model.
Description of symbols:
It include clack box shell 1 in Fig. 1, back-fire relief disk 2, drainage hole 3, drainage pipeline 4, sealing cover 5, handle 6, inlet side 7, out
End 8.
Specific embodiment
In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, below in conjunction with attached drawing
And specific embodiment is described in detail.
It please refers to shown in Figure of description 1, the utility model is a kind of coldly with fire arrester, including 1 He of clack box shell
Back-fire relief disk 2.The clack box shell 1 is the small spindle structure broad in the middle in both ends, and the clack box shell 1 includes inlet side 7 and outlet
8；The inlet side 7 of the clack box shell 1 and the outer surface of outlet 8 are equipped with flange；The middle part of the clack box shell 1 is set there are two phase
Pair the different outwardly projecting groove of height；The inside of the clack box shell 1 is equipped with inclined back-fire relief disk 2, the back-fire relief disk 2
Both ends be tightly attached to the inner wall of the groove respectively；The outer wall of the lower groove in position is equipped with row in described two grooves
Water hole 3, the external drainage pipeline 4 of the drainage hole 3.
As preferred and non-limiting, dictyosome of the back-fire relief disk 2 including multiple interval；The dictyosome includes made of metal core material
With fluorine resin layer.The material and structure can effectively prevent freezing.
As preferred and non-limiting, the outer wall of the higher groove in position is equipped with opening, institute in described two grooves
It states opening and is equipped with sealing cover 5, for safeguarding, replacing, maintaining the back-fire relief disk 2.
As preferred and non-limiting, higher one end of the back-fire relief disk 2 is equipped with handle 6, for being put into or taking out back-fire relief
Disk 2.
As preferred and non-limiting, the tilt angle of the back-fire relief disk 2 is 5 to 10 degree.The tilt angle can guarantee
In the case where the back-fire relief effect of back-fire relief disk 2, it effectively prevent droplets freeze.
The application method of the utility model are as follows: the utility model provides a kind of coldly with fire arrester, is mounted on combustibility
In pipeline, imflammable gas is flowed into from inlet side 7, is flowed out from outlet 8.Back-fire relief disk 2 can effectively prevent flame propagation.It is attached to back-fire relief
At water droplet, water droplet can glide Water vapor condensation on disk 2 along back-fire relief disk 2, flow into drainage hole 3, be discharged via drainage pipeline 4,
It effectively prevent droplets freeze to form blocking.
Above specific embodiment is only the preferred embodiment of this creation, all in this wound not to limit this creation
Any modification, equivalent substitution, improvement and etc. done within the spirit and principle of work, should be included in this creation protection scope it
It is interior.
