Detailed description of the invention
Describe embodiment below in conjunction with accompanying drawing and concrete elaboration is done to the utility model.
Embodiment one: the retaining mechanism 11 of the present embodiment is cone end holding screw, and sealing gasket is polytetrafluoroethylene (PTFE) plain cushion 9, and filter core diameter is 80mm.
As Fig. 1-2, a kind of flexible membrane filter core jockey, comprise orifice plate 7, filter core mount pad 8, polytetrafluoroethylene (PTFE) plain cushion 9, flexible membrane filter core joint 10, cone end holding screw 11, flexible membrane filter core joint 10 and filter core mount pad 8 are all tube structure, filter core mount pad 8 is welded on orifice plate 7, filter core mount pad 8 is sealing surface with the contact surface of orifice plate 7, filter core mount pad 8 coordinates with the hole of orifice plate 7, flexible membrane filter core joint 10 is arranged in filter core mount pad 8 and is connected with filter core mount pad 8, described flexible membrane filter core joint 10 adopts with described filter core mount pad 8 and is threaded, the screwing length of flexible membrane filter core joint 10 is longer than the screwing length of filter core mount pad 8, flexible membrane filter core joint 10 outer rim is provided with boss 10a, filter core mount pad 8 is provided with inner edge boss 8a, the lower surface of flexible membrane filter core joint 10 outer rim boss 10a and the end face of filter core mount pad 8 inner edge boss 8a arrange polytetrafluoroethylene (PTFE) plain cushion 9, the cone end holding screw 11 of 3 is set in filter core mount pad 8 top circumference, fully can contact with flexible membrane filter core joint 10 after described cone end holding screw 11 screws, to such an extent as to fully lock flexible membrane filter core joint 10, and also near described outer rim boss 10a upper surface on described outer rim boss 10a upper surface.Cone end holding screw quantity determines according to filter core diameter, generally, when filter core diameter≤80mm is just with 3 cone end holding screws, 80-150mm just bores end holding screws with 4, with 6 cone end holding screws during 150-250mm, described filter core diameter is the nominal diameter inside filter core model, the not diameter of filter core head junction, generally, the joint diameter of filter core is greater than filter core diameter 20-30mm, select 80mm, for one uses size comparatively frequently; At flexible membrane filter core joint 10 top, mounting groove 12 is set, be convenient to the installing/dismounting of filter core, adopt special extracting tool during dismounting, this instrument is tube-in-tube structure, and one end is processed with double wedge, match with the mounting groove 12 at filter core joint 10 top, the other end is processed with through hole, during dismounting, is first come loose by lock-screw 11, again the iron rod of applicable size is inserted through hole, pull flexible membrane filter core joint 10 counterclockwise.
Filter core mount pad 8 is welded on orifice plate 7, with this, filter core mount pad 8 is fixed on orifice plate 7, and can be sealed after welding.
Above-mentioned structure, compare current rigid film jockey or be referred to as rigidity filter core jockey, the conical surface can be processed in the hole of the rigidity filter core orifice plate 6 of rigid film jockey, in order to ensure the Surface Machining error of conical seal (contact) face within the specific limits, processing cost just improves thus, from stressed situation, the weight of original structure rigidity filter core 2 acts on the conical surface, so the intensity of rigidity filter core orifice plate 6 will be considered, so thickness is larger, therefore weight also increase, and the orifice plate 7 of the present embodiment, processing through hole is only needed just can, stress surface is also become the plane of orifice plate 7 upper end from the conical surface in hole, the thickness of orifice plate also reduces thus.
The described filter core joint outer rim boss 10a lower surface of the present embodiment and the upper surface of filter core mount pad inner edge boss 8a are sealing surface, such employing flat seal, the requirement of encapsulant is reduced, selective wider, the basis meeting sealing property realizes cost and reduces.
Current rigid film jockey, rigid film is fixed by pressing plate 3 and spring 100, branched filter core is because all adopt same pressing plate 3, filter core is influenced each other by spring 100 and pressing plate 3, therefore will consider overall sealing, and the sealing of each filter core of the present embodiment is all separate, therefore the problem simultaneously will considering overall sealing together can not be there is, be independent of each other sealing effectiveness thus, and installation difficulty reduces, and increases work efficiency.
Embodiment two: as Fig. 3, with the difference of embodiment one be, filter core mount pad 8 is not welded on orifice plate 7, arrange boss 7a in described orifice plate 7 hole, arrange sealing gasket 9 between filter core mount pad 8 outer rim boss 8b lower surface and inner convex platform 7a upper surface, orifice plate 7 hole, orifice plate 7 arranges screw thread in hole, filter core mount pad 8 bottom outer rim arranges screw thread, between cooperatively interact, by sealing gasket 9 and screw thread, reach sealing effectiveness with this.
