Description of drawings
By reading the detailed description of non-limiting example being done with reference to following accompanying drawing, it is more obvious that other features, objects and advantages of the present utility model will become:
Fig. 1 illustrates a kind of internally-arranged type return filter of the present utility model and splits structural representation;
Fig. 2 illustrates the installation applied environment schematic diagram of a kind of internally-arranged type return filter of the present utility model.
The specific embodiment
Come a kind of internally-arranged type return filter of the present utility model is done explanation in further detail below in conjunction with specification drawings and specific embodiments.
Fig. 1 illustrates a kind of internally-arranged type return filter of the present utility model and splits structural representation.As shown in Figure 1, described internally-arranged type return filter comprises filter cylinder 401, filter core 402, spring 403, pad 404, gland 405, plug 406 and trip bolt 407.
Particularly, filter cylinder 401 surfaces are provided with some through holes, and the sealing of one end also is provided with counterbore locating slot, other end opening; The sealing of filter core 402 1 ends also is provided with positioning boss, and other end opening also is provided with sealing O shape circle; Gland 405 comprises a spill port, and the one end is provided with boss.
With reference to figure 1, filter core 402 filter cylinder 401 of packing into, filter core 402 are positioned the position of the counterbore locating slot in the filter cylinder 401 by the positioning boss on it; A side that has boss of gland 405 inserts in an end of the sealing O shape circle of institute's filter core 402.Spring 403 is the common cylinder helical spring, is installed between the end face of filter core 402 open ends and gland 405 band boss, and wherein, described spring 403 is nested in outside the sealing O shape circle of described filter core 402.Pad 404 is a rubber washer, and pad is located between filter cylinder 402 and the gland 405.Gland 405 connects the openend of filter cylinder 401 by trip bolt 407.Plug 406 plugs can insert the oil return pipe (not shown) in this spill port in the spill port of the outside of gland 405, plug 406 has guaranteed the sealing of spill port and oil return tube connector interface.
In one embodiment, filter cylinder 401 adopts the stainless steel manufacturing.This is because stainless steel surfaces is need not coating protection antirust, has stopped fluid secondary pollution hidden danger
