Description
Technical field
The utility model relates to the relief valve unit in the gas burning system of natural gas vehicle engine, is particularly useful for the high-pressure filteration structure of vehicle CNG reduction valve.
Background technique
In CNG compressed natural gas, contain a lot of granule foreign gas such as water, machine oil, hydrogen sulfide, if used for a long time, impurity gas can enter reduction valve inside, cause the inner accumulation of mud of reduction valve, likely can affect gas-entered passageway or foreign gas and likely can enter in gas rail nozzle through reduction valve, defective nozzle; Therefore before rock gas enters reduction valve, design high-precision filtration filter core, filters granule foreign in rock gas, guarantees that reduction valve and nozzle can be not damaged.At present a lot of reduction valve filtrating equipments are all generally that the powder metallurgy that felt or sintering are formed directly embeds in reduction valve gas-entered passageway, then utilize cutting ferrule and cutting ferrule bolton high-pressure pipe, felt or powder metallurgy filter precision are more coarse, can not meet the requirement of high-precision filtration fine particles, this kind of structure brought very large inconvenience to C&M simultaneously, when changing or maintain, the high-pressure pipe of not only must first will dismantling, but also to change cutting ferrule.
Summary of the invention
Coarse in order to overcome general reduction valve filter core filter precision, the complicated loaded down with trivial details problem of dismounting maintenance service, the utility model has proposed a kind of new design proposal for filter core form and the structure of reduction valve high-pressure filteration.
The technical scheme in the invention for solving the technical problem is: comprise Y type tunnel tube, high-pressure filteration filter core, plug, described Y type tunnel tube is by filter core tunnel tube being housed and main gas-entered passageway pipe forms, filter core tunnel tube and main gas-entered passageway pipe infall are housed, aforesaid limited location annulus heavy stand A and the spacing annulus heavy stand B successively of being equipped with in filter core tunnel tube pipe from top to bottom, in main gas-entered passageway pipe pipe, there is main gas-entered passageway, netted stainless steel cylinder sleeve has glass fibre cylinder to form, high-pressure filteration filter core, it is characterized in that high-pressure filteration filter core one end is inserted is equipped with in filter core tunnel tube, netted stainless steel cylinder one end and spacing annulus heavy stand A are close to, glass fibre cylinder one end and spacing annulus heavy stand B are close to, plug is connected with the mouth of pipe internal thread that filter core tunnel tube is housed, plug end face props up the other end of netted stainless steel cylinder and glass fibre cylinder, high-pressure filteration filter core is fixed on to be equipped with in filter core tunnel tube.
Also have, glass fibre cylinder and netted stainless steel cylinder interference fit, an end face is concordant, and the netted stainless steel cylinder in other end is than the long 2mm of glass fibre cylinder.
Also the diameter of limited location annulus heavy stand A is less than spacing annulus heavy stand B diameter, and the platform discrepancy in elevation is 2mm between the two.
Further, the diameter of spacing annulus heavy stand A equals netted stainless steel outside diameter of cylinder, and spacing annulus heavy stand B diameter equals glass fibre outside diameter of cylinder.
Further, be equipped with between filter core tunnel tube and plug rear end root and have O RunddichtringO, and have respectively O type circle groove A and O type circle groove B at both.
The beneficial effects of the utility model are: this clearance filter filter precision is high, and gas filtration area is large, and specific filtration resistance is more abundant." Y " type support lug structure is simple, and maintenance operations is very convenient.
