It is avoided that the bending of spring during use.
This utility model is further arranged to: described screw is provided with the fixed block passed for spring.
Fixed block has guide effect, further fixes spring, when spring housing is connected on outside screw, is limited by fixed block,
Remain at horizontal level, it is to avoid the fault caused deviate from by spring.
This utility model is further arranged to: described valve pocket is bolted with hydraulic fluid port.
Can be dismounted valve pocket by the bolt on dismounting valve pocket, the housing configuration that bolt is fixed is simple, and connection can
Lean on.
This utility model is further arranged to: described valve pocket is provided with external screw thread, is provided with and coordinates with valve pocket sealing in hydraulic fluid port
Female thread.
Valve pocket is threadeded with hydraulic fluid port, it is only necessary to turns on valve pocket and just can be replaced the check valve in filter, during operation
Between short.
This utility model is further arranged to: the contact surface of described first check valve and the second check valve is provided with some bullets
Property buffer stopper.
First check valve and the second check valve collide abutting after having medium to be passed through filter, and velocity of medium difference causes impulse force
Difference, the lower check valve of long-time collision is easily damaged, and check valve is protected by the impulse force that elastic buffer block energy buffer medium brings
Protect, increase the service life of check valve.
This utility model is further arranged to: be provided with drainage screen in described hydraulic fluid port.
Medium is not filtered when entering filter, and medium is tentatively filtered by drainage screen, it is to avoid the impurity in medium
Causing the blocking of hydraulic fluid port, user can be dismantled lower valve sleeve easily and be replaced drainage screen.
By using technique scheme, this utility model has the advantages that spring is fixed firmly, in filter
Be convenient for changing the parts of damage, check valve can be individually replaced.
Compared with prior art, the utility model has the advantage of: spring fixation is difficult to when abjection, spring breaking down hold
Easily change.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment 1: a kind of bidirectional hydraulic filter, such as Fig. 1 and Fig. 2, including filter 1 and housing 2, filter 1 has for
Two hydraulic fluid ports 3 of turnover medium, medium is filtered by the defecator in housing 2.A valve it is respectively provided with in two hydraulic fluid ports 3
Set 4, valve pocket 4 is fixed by the bolt 15 tightened with filter 1.The first check valve 5 and the second check valve 6 it is provided with between two valve pockets 4,
The spring 7 of compression it is provided with between the first check valve 5 and the second check valve 6.Such as Fig. 3, valve pocket 4 and filter 1 are fixing by bolt 15, can
Take off valve pocket 4 with demounting bolt 15, spring the 7, first check valve the 5, second check valve 6 in valve pocket 4 is replaced.
Such as Fig. 4, the first check valve 5 is provided with a screw 8, and by the left end of spring 7, (orientation of following indication is accompanying drawing
