The purpose of this utility model realizes like this, a kind of injection boiler stokehold fuel oil filter, it is characterized in that: described injection boiler stokehold fuel oil filter comprises the open-topped housing of a sealed bottom, described enclosure interior is formed with housing cavity, described housing cavity is horizontally arranged with fuel filter net, described housing sidewall one upper lateral part is provided with fuel filler, described housing sidewall opposite side is provided with fuel outlet, described fuel filler is positioned at described fuel filter side on the net, described fuel outlet is positioned at described fuel filter side off the net, described housing cavity top has been threaded connection a seal cover, sealing ring is provided with between described case top and described seal cover, the first through hole is provided with bottom described housing sidewall, described first through hole is externally connected to relief valve.
In a better embodiment of the present utility model, described case top is provided with an annular groove, and described annular groove inside arranges described sealing ring.
In a better embodiment of the present utility model, described sealing ring is O type circle.
In a better embodiment of the present utility model, described housing cavity comprises upper cavity and lower chamber, and the diameter of described upper cavity is greater than the diameter of described lower chamber, is formed with first step portion between described upper cavity and described lower chamber.
In a better embodiment of the present utility model, described fuel filler is positioned at above described first step portion, and described fuel outlet is positioned at below described first step portion.
In a better embodiment of the present utility model, described first step portion arranges described fuel filter net.
In a better embodiment of the present utility model, described relief valve is ball valve.
In a better embodiment of the present utility model, the quantity of described first through hole is one or more, and the quantity of described relief valve is identical with the quantity of described first through hole.
From the above mentioned, injection boiler stokehold of the present utility model fuel oil filter, have employed seal with screwed joint lid and installs sealing ring additional and seal, and effectively avoids the seepage of fuel oil, improves sealing; This injection boiler stokehold fuel oil filter sidewall bottom arranges relief valve, dismantles, improve the security of unloading process after bleeding off inner overbottom pressure and residual fuel oil.
Accompanying drawing explanation
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein:
Fig. 1: be injection boiler stokehold of the present utility model fuel oil filter structural representation.
Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described.
As shown in Figure 1, the injection boiler stokehold fuel oil filter 100 that the utility model provides, comprise the open-topped housing 1 of a sealed bottom, housing 1 inside is formed with housing cavity 11, housing cavity 11 is horizontally arranged with fuel filter net 2, in the present embodiment, housing cavity 11 comprises upper cavity 111 and lower chamber 112, the diameter of upper cavity 111 is greater than the diameter of lower chamber 112, be formed with first step portion 113 between upper cavity 111 and lower chamber 112, the fuel filter net 2 filtered for fuel oil is arranged on first step portion 113.Housing 1 sidewall one upper lateral part is provided with fuel filler 12, housing 1 sidewall opposite side is provided with fuel outlet 13, fuel filler 12 is positioned at above fuel filter net 2, fuel outlet 13 is positioned at below fuel filter net 2, fuel filler 12 is positioned at above first step portion 113, and fuel outlet 13 is positioned at below first step portion 113.Housing cavity 11 top has been threaded connection a seal cover 3, sealing ring 4 is provided with between housing cavity 11 top and seal cover 3, housing 1 sidewall bottom is provided with the first through hole 14, first through hole 14 is externally connected to relief valve 5, relief valve 5 generally adopts ball valve, in the present embodiment, the quantity of the first through hole 14 is one or more, and the quantity of relief valve 5 is identical with the quantity of the first through hole 14.
Further, housing 1 top is provided with an annular groove 114, and annular groove 114 inside arranges described sealing ring 4.In the present embodiment, sealing ring 4 is O type circle, and for improving the sealing ring life-span, O type circle adopts oil-resistant high-temperature material.
