Description
Technical field
The utility model relates to a kind of natural filtering technique, is specifically related to a kind of CNG pneumatic filter.
Background technology
In CNG Gas Industry, CNG natural gas private filter is most important for filling machine at present.
Generally, because CNG natural gas just arrives gas station through links such as exploitation, conveying, sale, transportations, then be filled into by CNG filling machine in the gas bomb of gas-fueled vehicles.Thereby CNG filling machine is that CNG natural gas comes out to end user's " throat " equipment from exploitation, so for CNG filling machine, for guaranteeing the good overall performance of CNG filling machine, choose the outstanding CNG natural gas private filter of a combination property most important.
Therefore,, for the demand of prior art, be necessary to provide a kind of CNG pneumatic filter of new structure.
Utility model content
In view of this, the purpose of this utility model is the problem and shortage existing for existing natural gas filter, and a kind of suitable CNG pneumatic filter is provided.
For achieving the above object, the utility model provides following technical scheme:
A kind of CNG pneumatic filter, distribution bolt, the outlet connection being connected with valve body, the inlet attack being connected with valve body, the filter core that is positioned at valve inner, filter core support, filter core sealing gasket, the blowdown valve body being connected with valve body, the blowdown valve rod that is positioned at blowdown valve inner and blowdown nut that it comprises valve body, coordinates with valve body, described filter core employing copper powders sintering.
Preferably, in above-mentioned CNG pneumatic filter, between described distribution bolt and valve body, be provided with O RunddichtringO.
Preferably, in above-mentioned CNG pneumatic filter, between described valve body and outlet connection, be provided with O RunddichtringO.
Preferably, in above-mentioned CNG pneumatic filter, the filter core sealing gasket that described filter core sealing gasket is polytetrafluoroethylmaterial material.
Can find out from technique scheme, CNG pneumatic filter of the present utility model is elegant in appearance, and filtering accuracy is high, and circulation area is large.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing relevant of the present utility model in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structure cutaway view of the utility model CNG pneumatic filter.
The specific embodiment
The problem and shortage that the utility model exists for existing natural gas filter, discloses a kind of suitable CNG pneumatic filter.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is described in detail, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to the scope that the utility model is protected.
As shown in Figure 1, the disclosed CNG pneumatic filter of the utility model, it comprises valve body 3, the distribution bolt 1 coordinating with valve body 3, the outlet connection 5 being connected with valve body 3, the inlet attack 8 being connected with valve body 3, the filter core 7 that is positioned at valve body 3 inside, filter core support 10, filter core sealing gasket 9, the blowdown valve body 11 being connected with valve 3, the blowdown valve rod 12 that is positioned at blowdown valve body 11 inside and blowdown nut 13, and described filter core 7 adopts copper powders sintering.
Between described distribution bolt 1 and valve body 3, be provided with an O RunddichtringO 2.
Between described valve body and outlet connection, be provided with the 2nd O RunddichtringO 4 and the 3rd O RunddichtringO 6.
The filter core sealing gasket that described filter core sealing gasket 9 is polytetrafluoroethylmaterial material.
The operation principle of CNG pneumatic filter of the present utility model is: CNG gases at high pressure enter and carry out contaminant filter through inlet attack 8, foreign gas enters in filter chamber along inner fabrication hole, after dielectric gas is filtered by the filter core 7 of copper powders sintering, then flow out by fabrication hole; In the time that dielectric gas is filtered, will be filtered if any impurity, be attached to filter core 7 surfaces or drop below filtration cavity, while needing blowdown, open and filter the blowdown valve body 11 that cavity below arranges, the spiral air flow that utilizes powerful air inlet to produce, by external the impurity discharge filter that is attached to filter core 7 surfaces and drop below filtration cavity.
Can find out from technique scheme, CNG pneumatic filter of the present utility model is elegant in appearance, and filtering accuracy is high, and circulation area is large.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the utility model.Any Reference numeral in claim should be considered as limiting related claim.
In addition, be to be understood that, although this description is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should make description as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
