Description
Technical field
The utility model belongs to a kind of spark arrester, particularly relates to a kind of unidirectional spark arrester.
Background technology
Spark arrester is the safety device for preventing the propagation of flame of inflammable gas and flammable liquid steam.It is typically mounted at
In the pipeline of transporting combustible gases or ventilation groove tank on, prevent propagating flame (detonation or detonation) by device, by hindering
Fiery core, spark arrester shell and attachment are formed, and installation check valve is usually also needed to during spark arrester is installed, and two equipment are same
When install, occupied space is big, and of high cost.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of unidirectional spark arrester, both plays the role of check valve,
It can play the role of spark arrester in the case where catching fire again.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
The utility model is a kind of unidirectional spark arrester, including back-fire relief body and upper cover, in being internally provided with for back-fire relief body
Fire-resistant block is provided in one end of fire-resistant block into air parcel, spring jacking block is set in the other end of fire-resistant block, into air parcel and back-fire relief
It is provided between body into air parcel O-ring, the screw thread mouth of one end into air parcel and back-fire relief body is provided with phenyl tetrafluoride pad, spring top
One end of block is connected by spring with into gaseous core, and the other end of spring jacking block is provided with and goes out the thimble of air parcel connection, goes out air parcel
It is connected with upper cover.
Further improvement of the utility model is：Into gaseous core and into setting rubber pad between air parcel.
Further improvement of the utility model is：Between back-fire relief body and upper cover be equipped with upper cover O-ring, back-fire relief body and
Upper cover is tightly connected by upper cover O-ring.
The beneficial effects of the utility model are：The utility model is combined check valve and spark arrester are two-in-one, into
This is low, installs and occupies little space, and not only plays the role of check valve, but also the work of spark arrester can be played in the case where catching fire
With.
The utility model is simple in structure, design is rationally novel, easy to operate.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
In order to deepen the understanding to the utility model, the utility model is done further below in conjunction with drawings and examples
It is described in detail, which is only used for explaining the utility model, and the scope of protection of the utility model is not formed and is limited.
As shown in Figure 1, the utility model is a kind of unidirectional spark arrester, including back-fire relief body 1 and upper cover 12, in the back-fire relief
Body 1 is internally provided with fire-resistant block 5, is provided in one end of the fire-resistant block 5 into air parcel 4, in the another of the fire-resistant block 5
End sets spring jacking block 8, O-shaped into air parcel described into being provided between air parcel 4 and the back-fire relief body 1 into air parcel O types circle 3
Circle 3 is O-ring made of fluorine glue, and the screw thread mouth of described one end into air parcel 4 and the back-fire relief body 1 is provided with phenyl tetrafluoride pad
2, phenyl tetrafluoride pad is polytetrafluoroethylene (PTFE) pad, and one end of the spring jacking block 8 is connected by spring with into gaseous core 7, it is described into gaseous core 7 and
It is described that into rubber pad 6 is set between air parcel 4, the other end of the spring jacking block 8 is provided with and goes out the thimble 9 of the connection of air parcel 11,
It is described go out air parcel 11 be connected with the upper cover 12, between the back-fire relief body 1 and upper cover 12 pass through upper cover O-ring 10 sealing connect
It connects.
The working media of the unidirectional spark arrester of the utility model is the fuel gas such as oxygen, hydrogen, operating pressure 20Mpa,
Unidirectional spark arrester is made of SS316 materials, and due to the influence of high temperature, the thawing of fire-resistant block 5 has blocked the intensity of a fire.
