In the figure: the filter block 1, the input port 2, the output port 3, the filter screen plug 4, the screwing nut 41, the screw thread 42, the compression ring 43, the through hole 44, the filter cavity 5, the filter screen 6, the attaching circular ring 61, the filter screen cover 62, the buffer cavity 7 and the sealing ring 8.

Detailed Description

As shown in fig. 1-6, a lubrication valve block with filtration comprises a filter block 1 which is a cuboid, wherein two ends of the filter block 1 are respectively provided with an input port 2 and an output port 3, the middle part of the filter block 1 is provided with a filter cavity 5 which is opened upwards, one side of the filter cavity 5 is communicated with the input port 2, the lower part of the filter cavity 5 is communicated with the output port 3, a filter screen 6 is arranged in the filter cavity 5 and compresses the lower part of the filter cavity 5 through a filter screen plug 4, and the upper part of the filter cavity 5 is sealed by the filter screen plug 4.

Grease enters the filter cavity 5 through the input port 2, enters the output port 3 downwards after being filtered by the filter screen 6, the whole valve block is simple in structure and convenient to process, and when the filter screen 6 needs to be cleaned, the filter screen 6 is taken down only by taking down the interface of the filter screen plug 4, so that the valve block is convenient and quick.

The lower part of the filter screen 6 is a circular attaching ring 61, the lower end surface of the attaching ring 61 contacts with the lower end surface of the filter cavity 5, the inner edge of the attaching ring 61 is provided with a filter screen cover 62 connected with the inner edge, and the top of the filter screen cover 62 is folded.

The structure of the annular filter screen cover 62 attached to the annular ring 61 and the inner edge exposes the outer edge to facilitate the compression of the filter screen plug 4, so that the filter screen cover 62 becomes a boundary between the filter cavity 5 to be filtered and the filtered.

The filter screen plug 4 comprises a screw cap 41, a screw thread 42 is arranged at the lower end of the screw cap 41, a compression ring 43 is arranged at the lower end of the screw thread 42, a plurality of through holes 44 are formed in the compression ring 43, the screw thread 42 and the compression ring 43 are of a hollow structure, and the hollow interior is used for accommodating a filter screen cover 62.

The screw thread 42 is tightly pressed on the attaching circular ring 61 of the filter screen 6 through the lower end of the pressing ring 43 after being tightly screwed, and lubricating grease enters the screw thread 42 and the hollow inside of the pressing ring 43 through the through hole 44 and passes out of the attaching circular ring 61 to enter the output port 3 after being filtered through the filter screen 62.

A gap exists between the outer wall of the clamp ring 43 and the interior of the filter chamber 5.

The gap between the outer wall of the compression ring 43 and the inside of the filter cavity 5 serves as a buffer before entering the inside of the filter screen plug 4, and can be hollow inside by entering through the through holes 44 around the outside of the compression ring 43 for a circle, so that the efficiency is quickened through entering from a plurality of through holes.
