Abstract
The utility model discloses a kind of powder metallurgy oil strain mouth.The oil strain mouth includes powder metallurgy integration and fires the cylinder formed, it is characterised in that：The cylinder is provided with centre bore, and the center bore inner wall is provided with the screening plant in impurity screening.Solve and commonly use oil strain mouth in the prior art and can not filter impurity in fluid completely, screen pack is blocked by impurity, cause oil strain mouth can not normal work the problem of.The oil strain mouth is advantageous to improve the degree of purity of fluid, ensure that engine normal table works.
Description
Technical field
It the utility model is related to a kind of oil strain mouth, more particularly to a kind of oil strain mouth made of last metallurgy.
Background technology
Existing Chinese patent database discloses is made oil strain mouth so as to reach oil strain effect with powder metallurgy.Patent Shen
Please number CN201220309626.7, the applying date is：2013-03-20, data of publication of application are：CN202802971U, the inventive features
It is cylinder to be oil strain mouth body, and cylinder is fired by powder metallurgy integration and formed, and has oilhole, the surrounding of oilhole among cylinder
Provided with several semicircle waist holes, the fascia edge of cylinder is provided with flange, and groove is provided between upper lower flange.The powder metallurgy oil strain
Mouth can only filter fluid small particles impurity, can not filter large granular impurity, therefore can not improve the degree of purity of fluid completely.
Utility model content
The purpose of this utility model is in view of the deficienciess of the prior art, providing a kind of screening oil residue, purification oil
The oil strain mouth of liquid.
In order to realize the purpose of above-mentioned novel practical, the scheme that this powder metallurgy oil strain mouth provides is：
The cylindrical tube that forms is fired in a kind of powder metallurgy oil strain mouth, including powder metallurgy integration, the cylinder it is interior
Wall is provided with the screening plant for impurity screening.
During utility model works, cylinder is made up of powder metallurgy, is filtered due to containing many void ratios in mealy structure
Net is also small, therefore cylinder inboard wall can be with filter small particles impurity.Filter is advantageous to filter large granular impurity, and then will be big
Little particle impurity filters completely.
For the ease of the fixation and dismounting of filter, the inner barrel is provided with for overlapping convex shoulder with filter basket.
It is connected and ensures the consolidating of screening plant for the ease of screening plant and cylinder, the screening plant included
Filter basket body, the body are provided with the flange with convex shoulder overlap joint, and the body interior is provided with grid, placed on the grid
There is the screen pack for filtering large granular impurity.
In order to ensure that the powder metallurgy oil strain mouth and external device the cylinder both ends inwall that is connected are provided with and peripheral hardware
The internal thread of device connection.
In order to prevent fluid from being revealed from oil strain mouth two-port, the cylinder both ends open up groove, are provided with the groove
Internal thread, the bottom portion of groove are provided with sealing ring.
Compared with prior art, the beneficial effects of the utility model are:Screening plant is installed in oil strain mouth, was advantageous to
Size impurity in oil strain liquid, and then the degree of purity of fluid is improved, so as to ensure that the work of engine normal table.
Brief description of the drawings
Fig. 1 is the structural representation of the powder metallurgy oil strain mouth.
In figure：1 internal thread, 2 sealing rings, 3 convex shoulders, 4 filter baskets, 41 flange, 42 grids, 43 screen packs, 5 grooves, 6 carry
Beam, 7 cylinders.
Embodiment
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate, it should be understood that these embodiments are only
For illustrating the utility model rather than limitation the scope of the utility model, after the utility model has been read, this area
Modification of the technical staff to the various equivalent form of values of the present utility model falls within the application appended claims limited range.
As shown in figure 1, the cylinder 6 formed is fired in a kind of powder metallurgy oil strain mouth, including powder metallurgy integration.Cylinder 6
Inwall is provided with the screening plant of impurity screening.Screening plant includes the body of filter basket 4, and filter basket 4 is provided with to be overlapped with convex shoulder 3
Flange 41, flange 41 is welded and fixed with filter basket 4, and the body of filter basket 4 is internally provided with grid 42, is welded with the grid 42
Screen pack 43, the inwall of cylinder 7 are welded with the convex shoulder 3 for being overlapped with filter basket 4, and the top of filter basket 4 is articulated with bale handle 6, cylinder
The both ends inwall of body 4 is provided with the internal thread 1 being connected with external device, and the both ends of cylinder 7 open up groove 5, are provided with the groove 5 interior
Screw thread 1, the bottom of groove 5 are provided with sealing ring 2.
During work, fluid is entered in the oil strain mouth from external equipment, and oil strain mouth body is fired by powder metallurgy integration
The cylinder 7 formed, it is also small containing many void ratio screen packs in mealy structure, therefore cylinder inboard wall can be miscellaneous with filter small particles
Matter.When fluid flows through the screening plant of the inside of cylinder 7 setting, the screen pack 43 set inside screening plant can filter bulky grain
Impurity, when impurity screening plant accumulation it is excessive when, cause oil strain mouth can not normal work when, operating personnel utilize screening plant
The bale handle 6 of upper setting extracts screening plant, using threaded connection, oil strain mouth both ends when oil strain mouth is connected with external equipment
Inside sets internal thread 1, and cylinder both ends open up groove 5, and internal thread 1 is located at the inwall of groove 5, and the bottom of groove 5 is provided with sealing ring
2, it ensure that fluid will not be revealed.
The utility model is not limited to above-described embodiment, on the basis of technical scheme disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour can is special to some of which technology
Sign makes some and replaces and deform, and these are replaced and deformed in the scope of protection of the utility model.
