Description
Technical field
This utility model relates to natural gas filter, particularly relates to a kind of CNG and adds gas column filter.
Background technology
Natural gas filter is widely used in high pressure compressed natural gas measuring equipment, adds gas column refueling mother station conduct
The visual plant of trade settlement, mass flowmenter is again the core component adding gas column, installs filter in mass flowmenter front end
It is necessary, the small foreign body granule in pipeline both can have been stoped to be brought in natural gas cylinder, it is also possible to play guarantor
Protect effusion meter and ensure the effect of the accuracy measured.The filtration device structure adding gas column employing in the market includes end mostly
Lid, housing, filter element, outlet, entrance, sewage draining exit.The existing gas column filtration device structure that adds is complicated, and end cap individually separates with filter element,
Clean filter element process relatively difficult, filter element could be dismantled after needing to disassemble end cap, then filter element is carried out or
Safeguard, in use bring great inconvenience.
Utility model content
The utility model proposes a kind of CNG and add gas column filter, solve CNG in prior art and add the filter of gas column filter
The problem of core difficult clean and maintenance.
The technical solution of the utility model is achieved in that a kind of CNG adds gas column filter, including end cap, housing and
Filter element, end cap is connected with housing and seals, and housing is provided with outlet, entrance, sewage draining exit and access hole, and end cap is connected with filter element,
For hollow structure and having gas port in surrounding in the middle part of end cap, filter element coordinates with housing seal.Filter element is with stainless steel insert
The filter element prepared of stainless (steel) wire.Outlet and entrance are connected with thread connecting joint or are connected with welded pipe joint.
This utility model has following beneficial effect: simple in construction, circulation area is big；End cap filter element is that integral type sets
Meter, convenient disassembly, it is simple to cleaned and changed filter element.
Accompanying drawing explanation
Fig. 1 is that this utility model CNG adds gas column filter.
Wherein: 1 end cap, 2 housings, 3 filter elements, 4 outlets, 5 entrances, 6 sewage draining exits, 7 gas ports, 8 sealing rings.
Detailed description of the invention
As it is shown in figure 1, this utility model provides a kind of CNG adds gas column filter, including end cap 1, housing 2 and filter element 3,
End cap 1 is threadeded with housing 2 and is passed through sealing ring 8 and seals, and housing 1 is provided with two outlet 5, blowdowns of 4, entrance
Mouth 6 and an access hole, end cap 1 is threaded connection with filter element 3, for hollow structure and has inducing QI in surrounding in the middle part of end cap 1
Hole 7, filter element 3 is coordinated by sealing ring 8 sealing with housing 2.Filter element 3 is filter element prepared by the stainless (steel) wire with stainless steel insert
3.Outlet 4 and entrance 5 are connected with thread connecting joint or are connected with welded pipe joint.
Work process of the present utility model: high-pressure natural gas enters CNG from entrance 5 and adds gas column filter, and natural gas passes through
It is internal that filter element 3 enters filter element 3, and the natural gas after filtration is by the hollow structure in the middle part of end cap 1, then is passed into by gas port 7
Outlet 4, filter outlet 4 connects main process pipeline, and the small foreign body granule in pipeline is filtered at filter element 3 outer surface, just
In the case of Chang, can be by sewage draining exit 6 by most impurity discharge filter.When filter needs to clean, can directly dismantle
Filter end cap 1, end cap 1 is taken filter element 3 out of, is carried out filter element 3 safeguarding.
