Abstract
The invention discloses a pipe end flame arrester, belonging to the technical field of pipeline safety equipment. The pipe end flame arrester comprises a valve body and a flame arresting plate, wherein the flame arresting plate is fixed in the valve body through a bolt; the pipe end flame arrester is characterized in that an openable protective rain cover is also arranged on the valve body; a bolt cap is arranged on the protective cover and is connected with a fusible metal component together; a spring is also arranged on the valve body; and the pipe end flame arrester is mainly applied to pipeline and storage tank safety aspects.
Description
Technical field
The present invention relates to pipe safety equipment technical field, being specifically related to one can opening protection function canopy pipe end spark arrester.
Background technology
The tempering of flame when the explosion-proof type spark arrester of pipe end formula can prevent air detonation, protects when there is air detonation (blast) not damaged.The high temperature and high pressure that they produce when can bear inflammable gas/air mixture detonation.Air detonation can be stoped, but can not stop by the tempering of detonation initiation.
Existing pipe end formula explosion-proof type spark arrester generally adopts fixed protection canopy, and such design can directly cause spark arrester to have no idea continual and steady burning.Heat radiation back-fire relief ability under stable combustion case that these fixed apparatuses can limit spark arrester back-fire relief element further can further reduce, and causes spark arrester than tempering easier under open environment.Tempering phenomenon may a few minutes can occur after combustion, even only have a few second.
Summary of the invention
In order to overcome above-mentioned technical problem, the invention provides a kind of openable protection canopy pipe end spark arrester, the technical scheme of employing is as follows:
Pipe end spark arrester, comprises valve body and fire-proof plate, and fire-proof plate is fixed in valve body by bolt, it is characterized in that, valve body is also provided with openable protection canopy, protective cover is provided with nuts, nuts and fusible metal element link together, and valve body is also provided with spring.When in the process used, heat on fire-proof plate gets more and more, thus fusing fusible metal element, thus protective cover is flicked under the action of the spring, thus decrease the accumulation of heat on fire-proof plate, make in the whole emitting air of heat, thus reach that the safety of product is improve is many, and can the continual and steady burning of ability IIA and IIB gas.
The present invention has the following advantages:
1. the continual and steady burning of ability IIA and IIB gas.。
2. greatly increase the safety coefficient of product, provide safety guarantee for factory normally produces, for the safety of people is laid a good foundation.
Accompanying drawing explanation
Fig. 1 is the cut-away view of pipe end spark arrester of the present invention;
Fig. 2 is the using state device cut-away view of pipe end spark arrester of the present invention;
Fig. 3 is pipe end spark arrester using state schematic diagram of the present invention.
Detailed description of the invention
Embodiment 1
As Figure 1-3
Pipe end spark arrester, comprise valve body 5 and fire-proof plate 7, fire-proof plate 7 is fixed in valve body 5 by bolt 6, it is characterized in that, valve body 5 is also provided with can opening protection function canopy 1, protective cover is provided with nuts 4, nuts 4 and fusible metal element 3 link together, valve body 5 is also provided with spring 2, when in the process used, heat on fire-proof plate 7 gets more and more, thus fusing fusible metal element 3, thus protective cover 1 is flicked under the effect of spring 2, thus decrease the accumulation of heat on fire-proof plate 7, thus make in the whole emitting air of heat, thus reach that the safety coefficient of product is improve is many, and the continual and steady burning of energy ability IIA and IIB gas, be conducive to popularizing in an all-round way and application.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
