Steel pipe 3 is welded with SAE flange group 4 again, and SAE flange group is fixedly connected with the high-pressure hose 5 with SAE bump joint, with this
Mode accesses in hydraulic system pipeline.Such connection type needs to weld at 2, needs one group of (i.e. 2) SAE flange, element is more
And structure is complicated causes assembly difficulty high, furthermore because high pressure filter is generally used at hydraulic pump outlet, pressure is high and presses
Fluctuation is big, is all also easy to produce oil seepage phenomena in weld and SAE flange group bolt bearing.
Utility model content
The purpose of the utility model is to provide a kind of high pressure filter connection structure, with solve element in the prior art it is more,
Structure is complicated and weld is also easy to produce leakage of oil problem.
To achieve the above object, a kind of high pressure filter connection structure of the utility model adopts the following technical scheme that one
Kind high pressure filter connection structure, including the connecting flange for connecting with high pressure filter, connecting flange screwing is connected with
It is threaded with pipe fitting in SAE flange or connecting flange centre bore, is sealedly connected with flange in the centre bore of SAE flange and connects
Head is connected with high-pressure hose on bump joint or the other end of pipe fitting is connected with high-pressure hose.
The first screw hole is provided at four angles of the connecting flange for connecting with high pressure filter, on connecting flange
The second screw hole is provided between two the first screw holes on centre bore and a diagonal line for connecting SAE flange.
The quantity of second screw hole is two pairs and is arranged along the axisymmetrical of connecting flange centre bore, each pair of second spiral shell
Nail hole line between the center and the center of corresponding second screw hole of connecting flange centre bore is symmetrical arranged, and the two of every centering
Line is vertically arranged between a second screw hole center and corresponding first screw hole center.
The centre bore of the connecting flange is threaded hole.
First screw hole is counterbore.
The utility model has the beneficial effects that direct screw connects SAE flange on connecting flange, or reconnect flange
It is threadedly coupled pipe fitting in centre bore, eliminates a SAE flange and seamless steel pipe compared with the prior art, reduces parts number
Amount, structure is simple, and eliminates welding procedure, solves and is all also easy to produce in weld and SAE flange group bolt bearing
The problem of leakage of oil.
Further, it is provided between two the first screw holes on centre bore and a diagonal line on connecting flange
Second screw hole is for connecting SAE flange, while the centre bore of connecting flange is that threaded hole can connect pipe fitting, which can
With selection using SAE flange either pipe fitting, so that the connection structure is versatile, it is easy to use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of high pressure filter connection structure in the prior art；
Fig. 2 is a kind of structural schematic diagram of the embodiment one of high pressure filter connection structure of the utility model；
Fig. 3 is the structural schematic diagram of connecting flange in Fig. 2；
Fig. 4 is a kind of structural schematic diagram of the embodiment two of high pressure filter connection structure of the utility model.
Specific embodiment
A kind of embodiment one of high pressure filter connection structure of the utility model, as shown in Figures 2 and 3, including is used for
The connecting flange 2 connecting with high pressure filter 1,2 screwing of connecting flange are connected with SAE flange 3, in the centre bore of SAE flange 3
It is sealedly connected with bump joint 4, high-pressure hose 5 is connected on bump joint 4.The structure of connecting flange 2, as shown in figure 3, connection
Flange 2 is rectangular configuration, and the first screw hole 6 is provided at four angles of connecting flange 2 for connecting with high pressure filter 1, even
7 hole of the second screw is provided between two the first screw holes 6 on centre bore 8 and a diagonal line on acting flange 2 to be used for
Connect SAE flange 3.
The quantity of second screw hole 7 is two pairs and is arranged along the axisymmetrical of connecting flange centre bore, each pair of second screw
Hole line between the center and the center of corresponding second screw hole of connecting flange centre bore is symmetrical arranged, and two of every centering
Line is vertically arranged between second screw hole center and corresponding first screw hole center.First screw hole 6 is counterbore, in this way in spiral shell
Nail is screwed into the first screw hole 6, and screw head will not leak out, and will not influence the installation of SAE flange 3.The centre bore of connecting flange 2
8 be threaded hole, and threaded hole can choose installation pipe fitting, and the other end of pipe fitting is connected with high-pressure hose, when in use can be with
Pipe fitting and SAE flange are chosen to install, so that the connection structure is versatile, it is easy to use.
The embodiment two of a kind of high pressure filter connection structure of the utility model, as shown in figure 4, the area with embodiment one
It is not that SAE flange is not installed, and is threadedly coupled pipe fitting 9, the other end connection of pipe fitting 9 in the centre bore of connecting flange 2
There is high-pressure hose 5, realizes high pressure filter and be directly accessed to the system in pipeline by high-pressure hose.
It can be omitted welding procedure using above-mentioned connection structure, working hour not only be greatly saved, but also avoid weld
The failure risk of leakage of oil, it is only necessary to high-pressure hose be directlyed adopt a SAE flange or pipe fitting is fixed on connecting flange
On, element is simplified, and provide diversified connection type.
In the other embodiments of the utility model, the quantity of the second screw hole can be adjusted according to actual needs；Even
It can also be not provided with the second screw hole on acting flange, and be directly threadedly coupled pipe fitting in the centre bore of connecting flange；Connection
When being provided with the second screw hole on flange, the centre bore of connecting flange can not be screw hole at this time, can also be common mistake
Oilhole.
