The utility model is to realize like this, and it comprises the tubular shell that two ends link to each other with pipeline, and permanent magnet is set in the housing.
The housing two ends are connected with pipeline by joint, permanent magnet ringwise, its inwall is provided with annular protective jacket; Protective jacket two ends outward flanging is clamped by joint, and contacts with inner walls; Annular preserving and sealing bed course is set between protective jacket and permanent magnet; Preserving and sealing bed course two ends outward flanging, and contact with inner walls; Between protective jacket flange and preserving and sealing bed course flange lead ring is set, the preserving and sealing bed course is clamped by lead ring; Described housing, permanent magnet, lead ring, preserving and sealing bed course have two groups at least, connect by joint; The top of housing is connected with filter; Described filter comprises conical pan; The grid net is set in the toroidal cavity between pan and shell.
The utility model is owing to be provided with permanent magnet in housing, the protective jacket of tubular has completely cut off contacting of permanent magnet and chemical substance, avoided permanent magnet to be subjected to chemical attack and magnetic force is weakened; Permanent magnet has further been protected in the setting of preserving and sealing bed course.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model structure as shown in Figure 1, three cylindrical portions in upper, middle and lower, each part all has housing, adjacent housings connects by joint screw thread.
Top is filter, and it comprises the box oil connection 1 at top, and oil connection 1 lower surface has external screw thread, and its internal thread with filter housing 5 tops is complementary and is connected; Conical pan 4 is set in the filter housing, and the upper level flange of pan 4 contacts with oil connection 1 lower surface, and flange is pressed on the lower surface of oil connection 1 by last back-up ring 2; In the cavity that filter housing 5 and pan are 4 grid net 3 is set, it is full of cavity basically; The bottom of pan 4 is provided with centralizing bracket 7, plays the circumferentially effect of location of pan 4 bottoms that makes, and the edge of centralizing bracket 7 is by back-up ring 6 and lining 8 clamp down; Last back-up ring 2, following back-up ring 6 all closely contact with filter housing 5 inwalls with lining 8.
The middle part is that first highfield district part also has shell 11, it is threaded by two snapping heads 9 with filter housing 5, have cavity in the cylindrical outer casing 11, annular protective jacket 14 is set in the housing cavity, protective jacket 14 internal diameters are identical with two snapping head 9 internal diameters, in the toroidal cavity that protective jacket 14 and housing are 11 permanent magnet 12 is set, protective jacket 14 two ends outward flangings, and contact with housing 11 inwalls; 12 of protective jacket 14 and permanent magnets are provided with annular preserving and sealing bed course 13; Preserving and sealing bed course 13 two ends outward flangings, and contact with housing 11 inwalls; Between protective jacket 14 flange and preserving and sealing bed course 13 flange lead ring 10 is set; Protective jacket 14, lead ring 10, preserving and sealing bed course 13, permanent magnet 12 outer rims all closely contact with housing 11 inwalls, and these parts axially compress mutually.
Shell 11 bottoms are connected with second highfield district part of bottom by another pair snapping head 16, the structure of second highfield district part is identical with first highfield district part at middle part, it comprises same shell 21, protective jacket 20, permanent magnet 18, last lead ring 17, following lead ring 22, preserving and sealing bed course 19, and housing 21 bottoms are connected with oil pipe by oil connection 23.
Being provided with of protective jacket 14,20 is specific as follows: at first the expansion part with protective jacket carries out clip, and clip requires five equilibrium uniform, and the clip length requirement is identical; Be rolled into tubular by upper and lower side then, be placed in the preserving and sealing bed course, under the effect of special tool expansion force, make protective jacket external surface and preserving and sealing bed course inner surface bonding firmly, behind the some hrs, again with protective jacket two ends clip flange (special tool operation), make that it is bonding, press between lead ring and joint inner face.Take out special tool at last.
As the selection of protective jacket material, not only to consider characteristics such as acidproof, alkaline-resisting, oil resistant, heatproof, but also will consider non magnetic and plasticity.
