Description
Technical field
The utility model belongs to filter, particularly relates to a kind of oil absorption filter of diaphragm type compressor.
Background technique
Diaphragm type compressor is a kind of positive displacement compressor, determines that it has two major features by its structural characteristics: compression ratio is large, good airproof performance, the vitality place of this also diaphragm type compressor just.Its main operational principle is: by driving mechanism driven plunger or plunger reciprocating, piston or plunger promote fluid (fluid cannot compress) the drive diaphragm pressurized gas in oil cylinder, in film chamber, the volume of gas obtains change, achieves the object of gas compression under the cooperation of suction, outlet valve.Diaphragm type compressor is primarily of motor, base, crankcase, crankshaft link rod motion mechanism, part of cylinder block, oil gas pipeline, automatical control system and oil absorption filter composition.The oil absorption filter of conventional membrane compressor connects fuel tank and gear pump, drives oil pressure, released by fluid from fuel tank by gear pump work.When the contaminated thing of the filter core in filter blocks oil outlet, need repairing and more renew cartridge, now then all must release the oil in fuel tank.Each maintenance load is very large, reduces working efficiency.
Model utility content
The utility model is to overcome deficiency of the prior art, provides a kind of oil absorption filter of diaphragm type compressor, without the need to releasing the oil in fuel tank when maintenance or more renew cartridge, directly can take out filter core.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of oil absorption filter of diaphragm type compressor, comprise front cover, connection block, filter core and joint, described front cover and connection block spin, in the oil pocket of described cartridge support in the middle of front cover and connection block, be connected with filter core after described joint spins with connection block, it is characterized in that: between described filter core front end and front cover, in space, be provided with one-way valve, described filter core front end is connected with one-way valve, described one-way valve comprises valve plate and valve seat, described valve plate forms the T-shaped entirety of shape of cross section by circular valve plate and cylinder axis, described valve seat is provided with center hole, the cylinder axis of valve plate and the center hole of valve seat are slidably matched, described valve seat and front cover internal thread spin, in sealing state after described circular valve plate and valve seat planes touch, Compress Spring is equipped with between described circular valve plate front end and front cover, described valve base surface was circumferentially provided with oily circular hole.
Described cylinder axis right-hand member is provided with supports end cap, and supports end cap supports filter core one end.
Described valve base surface circumferential concentric circular shaft crosses oily circular hole to uniform 1-6.
In described front cover, dilapidated walls are provided with the concave station containing Compress Spring.
Beneficial effect: compared with prior art, the advantage that the utility model increases one-way valve is when the contaminated thing of the filter core in filter blocks oil outlet, and maintenance or more renew cartridge do not need to release the oil in oil box.After direct taking-up filter core, there is oil when avoiding maintenance or renewal part and leak, improve working efficiency.

In figure: 1, front cover, 1-1, concave station, 2, Compress Spring, 3, one-way valve, 3-1, circular valve plate, 3-2, cylinder axis, 3-3, supports end cap, 4, valve seat, 4-1, cross oily circular hole, 4-2, center hole, 5, filter core, 6, connection block, 7, joint.
Embodiment
Below in conjunction with preferred embodiment, to the embodiment provided according to the utility model, details are as follows:
Embodiment
Refer to accompanying drawing, compared with prior art, the utility model provides a kind of oil absorption filter of diaphragm type compressor, comprise front cover 1, connection block 6, filter core 5 and joint 7, described front cover and connection block spin, in the oil pocket of described cartridge support in the middle of front cover and connection block, be connected with filter core after described joint spins with connection block, one-way valve 3 is provided with in space between described filter core front end and front cover, described filter core front end is connected with one-way valve, described one-way valve comprises valve plate and valve seat 4, described valve plate forms the T-shaped entirety of shape of cross section by circular valve plate 3-1 and cylinder axis 3-2, described valve seat is provided with center hole 4-2, the cylinder axis of valve plate and the center hole of valve seat are slidably matched, described valve seat and front cover internal thread spin, in sealing state after described circular valve plate and valve seat planes touch, Compress Spring 2 is equipped with between described circular valve plate front end and front cover, described valve base surface was circumferentially provided with oily circular hole 4-1.
Preferred version of the present utility model is, described cylinder axis right-hand member is provided with supports end cap 3-3, and supports end cap supports filter core one end.
Preferred version of the present utility model is, described valve base surface circumferential concentric circular shaft is to uniform 6 oily circular holes of mistake.
Preferred version of the present utility model is, in described front cover, dilapidated walls are provided with the concave station 1-1 containing Compress Spring.
Working procedure: oil absorption filter adds one-way valve 3 and valve seat 4 on original filter basis, when machine run, compressing filter core 5 tightened by joint 7 makes the circular valve plate of one-way valve separate with valve seat 4, and fluid is just flowed out through filter screen filtration through the oil-through hole of one-way valve 3 with valve seat 4 by casing.When unloading connection block 6 with joint 7, Compress Spring 2 loses pressure, withstands one-way valve 3, and the circular valve plate of one-way valve 3 and valve seat 4 are tamping, fluid not by.
Above-mentioned detailed description of the oil absorption filter of this kind of diaphragm type compressor being carried out with reference to embodiment; illustrative instead of determinate; several embodiments can be listed according to institute's limited range; therefore in the change do not departed under the utility model general plotting and amendment, should belong within protection domain of the present utility model.
