Description

Wet type air filter

Technical field

The utility model is related to air filter technical field, more particularly to a kind of wet type air filter.

Background technology

Wet type air filter is used widely in middle low power tractor gas handling system, current air filter sealing structure letter It is single, be made up of upper tub assembly, lower tub assembly, sealing ring and net-filter assembly, air inlet pipe and net-filter assembly in upper tub assembly and O-ring seal is arranged between upper lower barrel body to be sealed, and is simply arranged between this kind of O-ring seal and above-mentioned part, Not only sealing effectiveness is poor, and easily comes off in use and servicing operations, and the dust granule in air enters empty by gap Filter, the air with particle and dust without bottom machine oil absorption, filtration be put into engine, easily cause engine Premature wear.

Utility model content

Technical problem to be solved in the utility model is：A kind of wet type air filter is provided, using radial seal and end face The sealing structure form of seal combination, improves the sealing effectiveness between internal each part, improves the strainability of air filter.

To solve above-mentioned technical problem, the technical solution of the utility model is：A kind of wet type air filter, including inner hollow Upper barrel body and lower barrel body, the lower end of the upper barrel body is open, and the upper end of the lower barrel body is open, the upper end set of the lower barrel body Enter in the lower end of the upper barrel body and corresponding with the inwall step of upper barrel body, and pass through between the upper barrel body and the lower barrel body Lock locking is integrated；

Air inlet pipe is fixed with the upper barrel body, the air inlet pipe is extended in the lower barrel body, on described Fixation in the air inlet pipe in staving is arranged with upper filter component, and the fixation in the air inlet pipe in the lower barrel body is arranged with Lower filter component, is arranged with the first sealing ring between the air inlet pipe and the lower filter component, and first sealing ring Upper end flange is located between the upper filter component and the lower filter component；

The inwall step of the inwall step of lower barrel body upper end open-mouth and upper barrel body lower end open-mouth it Between be provided with the second sealing ring.

Further, the lower end of first sealing ring is provided with lower end flange, and the lower end insertion of the air inlet pipe is described In the groove of lower end flange；

The upper end flange of the filter core exterior bowl of the lower filter component is inserted in the groove of corresponding second sealing ring.

Employ above technical scheme, the beneficial effects of the utility model：

Due to the first sealing ring between the air inlet pipe inside wet type air filter and lower filter component, the first sealing ring it is upper End boss is located between upper filter component and lower filter component, thus the first sealing between air inlet pipe and lower filter component Circle forms the radial seal of the position, and the upper end flange between upper filter component and lower filter component forms the end of the position Face seals, thus substantially increases the sealing between air inlet pipe and upper and lower element kit, it is to avoid flow out from air inlet pipe lower end Do not cross air filtering directly to flow to after top into engine from the gap between air inlet pipe, lower filter component and element kit； It is close due to being arranged with second between the inwall step of the inwall step of lower barrel body upper end open-mouth and upper barrel body lower end open-mouth Seal, thus the end face that the two ends for acting against the second sealing ring at upper and lower inner wall of barrel step respectively are formed between lower barrel body Sealing, the second sealing ring between upper and lower inner wall of barrel step forms the radial seal between upper lower barrel body, so as to fabulous Avoid extraneous air and directly enter inside staving from the place of being fastened and connected of upper lower barrel body, air is filtered to be directly entered and sends out Problem inside motivation, sealing ring overall structure is simple, and sealing effectiveness is greatly improved.

Because the lower end of the first sealing ring is provided with lower end flange, and the groove of the lower end insertion lower end flange of air inlet pipe； The upper end flange of the filter core exterior bowl of lower filter component is inserted in the groove of corresponding second sealing ring.Thus it is wet safeguarding During formula air filter, when lower barrel body is opened into replacing self-filtering fluid, because the first sealing ring is connected with air inlet pipe, the second sealing Circle is connected with the exterior bowl of lower filter component, thus will not be because of dropping after the support without lower barrel body, it is to avoid because missing Sealing ring and cause to reinstall wet filter sealing effectiveness difference problem.
