Abstract

The utility model discloses a plate filter, which comprises a tubular casing and a tubular filter core coaxially arranged in the casing. One end of the casing is fixed with a filter head matched with the casing in sealing mode, the filter head is provided with a liquid inlet channel and a liquid outlet channel, and the other end of the casing is provided with an end cover in sealing mode. A supporting plate matched with the filter core in clamping mode is fixed in the casing close to the end cover end, and the filter core is connected between the supporting plate and the filter head in butting mode. The central axial of the liquid outlet channel is close to the central axial of the casing. The plate filter is simple in structure and small in installation space.

Description

A kind of leaf filter

Technical field

The utility model relates to the board-like mesohigh filter that a kind of hydraulic equipment pipe-line system is used.

Background technique

The filter of present domestic use mostly is leaf filter and traditional tubular filter, the use of leaf filter has promoted the development of integrated valve block, but the leaf filter of domestic use mostly is the leaf filter that install the side, although promoted the development of integrated valve block, but, need provide the filter of more mounting types along with the raising of integrated valve block technical requirements.

Existing leaf filter as shown in Figure 1 and Figure 2, comprise housing 21, housing 21 1 end sealing and fixing have top cover 51, the other end sealing and fixing that filter 11 is arranged, in the housing 21 between filter 11 and top cover 51 the coaxial tubular element 31 that is equipped with, described top cover 51 is sleeved on the housing 21, and be top-loaded with spring 10 between top cover 51 and the filter core 31, complex structure, in addition, the centre distance of liquid entering hole and liquid outlet is bigger than normal, cause filter boundary dimension bigger than normal, can not satisfy the strict demand of integrated valve block installing space.

The model utility content

The purpose of this utility model provides a kind of simple in structure, and the little leaf filter of installation footprint.

The utility model adopts following technological scheme: a kind of leaf filter, comprise tubular shell and the coaxial tubular element that is arranged in the housing, described housing one end is fixed with the filter that cooperates with housing seal, offer liquid entering hole passage and liquid outlet passage on the filter, described housing the other end one sealing is provided with end cap, be fixed with the pallet of joining with described filter core card near the end cap end in the housing, described filter core apical grafting is between pallet and filter; The central axis of described liquid outlet passage is near the central axis of housing.

Described housing is fixedlyed connected by screw thread with described filter.

Offer circular groove with the filter threaded connection place along the housing circumferencial direction on the described housing, described go up to be furnished with in the circular groove be used for the housing cushion rubber that is sealed and matched with filter.

Offer down circular groove with the filter threaded connection place along the housing circumferencial direction on the described housing, be furnished with in the described down circular groove and be used for the tetrafluoro back-up ring that is sealed and matched with filter, described housing cushion rubber at tetrafluoro back-up ring and housing between the end face of filter one end.

Adopt the filter of said structure, be fixed with the pallet of joining near the end cap end in the housing with the filter core card, described pallet apical grafting is between filter and chuck, and the sealing of housing one end one is provided with top cover, and is simple in structure, in addition, the central axis of liquid outlet passage is near the central axis of housing, the centre distance of liquid entering hole and liquid outlet is less than normal, can guarantee that the boundary dimension of filter is enough little, thereby satisfy installation footprint.
