Abstract
The utility model discloses a kind of oil drilling pump valve body of modified node method, it is made up of valve cylindrical body, valve body taking-up groove hanging hole, rubber cup gland, rubber cup, valve body sealing surface, leading truck, cylindrical body welding block.It is characterized in that lower cylinder welds soon and leading truck welds together, valve body sealing surface screws fastening by screw thread and leading truck, and rubber cup is enclosed within above valve body sealing surface, screws fastening by rubber cup gland screw thread; Valve body takes out groove hanging hole and is provided with four hanging holes, is provided with groove around hanging hole.The utility model has the advantages that the easily damaged parts valve body sealing surface of oil drilling pump valve body can disassembling, assembling and replacing, take out easily faster, overcome traditional valve body sealing surface and damage the defect and valve body taking-up difficulty that cannot dismantle, assemble replacing, the problem that valve body entirety is scrapped.
Description
Technical field
The utility model belongs to the parts of oil drilling pump, is a kind of oil drilling pump valve body of modified node method concretely.
Background technique
For now widely used oil drilling pump, such as: 3NB-1300F, 3NB-1600F and 3NB-2200 drilling pump, traditions of the past design continued to use by its valve body assembly always, and valve body sealing surface wherein, valve rubber cup are easily damaged partss, dismounting and assembling is often needed to change in using at the scene, and, because its valve body sealing surface and valve cylindrical body are integrated, valve body takes out hanging hole has two to take out hanging hole on valve body pillar face, the defect that design exists; Damaging at valve body sealing surface constantly cannot disassembling, assembling and replacing, valve cylindrical body and valve sealing surface together can only be changed or scrapped, valve body takes out hanging hole and only has two, and in valve cylindrical body upper end, on oil drilling pump, water end (W.E.) is owing to taking out hanging hole directionality problem, takes out very difficult.In order to overcome this two problems, designer of the present utility model has done at the scene and has studied in earnest, proposes goal of the invention of the present utility model.
Summary of the invention
Goal of the invention of the present utility model is to overcome the upper defect existed of current oil drilling pump valve body structure design, cannot disassembling, assembling and replacing when valve body sealing surface damages, and together scraps together with valve body; Take out in difficult problem at valve body and put forward, namely a kind of oil drilling pump valve body of modified node method is provided.
Technical solution of the present utility model realizes like this, the oil drilling pump valve body of this modified node method, there is valve cylindrical body and be assemblied in the valve body sealing surface on cylindrical body on the contrary, and its distinguishing characteristics is that the valve body sealing surface being assemblied in valve cylindrical body bottom is tightened on valve body cylindrical body screw thread by screw thread, screw firmly with spanner by leading truck when screwing, rubber cup is enclosed within your sealing surface anti-by valve cylindrical body top, rubber cup gland is tightened on valve cylindrical body screw thread by screw thread, be connected firmly by six rib fasteners and leading truck with spanner when screwing.When taking out valve body, the oil drilling pump valve body of this modified node method, top has groove hanging hole, be uniformly distributed four holes in groove, the hook taking of valve body moved up and down, finds groove, then in groove, carry out circumference move, insert hole hook taking, above extract.
Advantageous Effects of the present utility model is: when oil drilling pump valve sealing surface damages, valve sealing surface is tightened with screw thread, rubber cup is enclosed within valve cylindrical body, valve body sealing surface and rubber cup at the scene can disassembling, assembling and replacings, solve over traditional oil drilling pump valve body sealing surface, rubber cup damage change time, together with the problem that valve body is together scrapped, more simple on manufacturing processing technic.
When taking out valve body, be difficult to see taking-up hanging hole, because valve body upper bands is fluted, four holes be evenly distributed are had in groove, as long as hook taking is carried out moving up and down finding groove on valve body top, in groove, carry out circumference move, soon hanging hole is inserted in hook taking, on carry by valve body take out, overcome traditional valve body be difficult to take out problem.
Accompanying drawing explanation
Accompanying drawing Fig. 1 is structural profile schematic diagram of the present utility model, and it is made up of valve cylindrical body, valve body taking-up groove hanging hole, rubber cup gland, rubber cup, valve body sealing surface, leading truck, cylindrical body welding block.Marking serial numbers in accompanying drawing Fig. 1 describes: 1 is valve cylindrical body, and 2 is that valve body takes out groove hanging hole, and 3 is rubber cup glands, and 4 is rubber cups, and 5 is valve body sealing surfaces, and 6 is leading trucks, and 7 is cylindrical body welding blocks.
Embodiment
Below in conjunction with accompanying drawing Fig. 1, structure of the present utility model is described in detail.
With reference to accompanying drawing Fig. 1, the oil drilling pump valve body of this kind of modified node method, it is characterized in that leading truck (6) is inserted on cylindrical body welding block (7), by being welded to connect in valve cylindrical body bottom, valve body sealing surface (5), by six rib fasteners on valve body sealing surface, valve body sealing surface is tightened on valve cylindrical body (1) outside thread with spanner, with leading truck (6) compact siro spinning technology, rubber cup (4) is enclosed within valve cylindrical body (1), rubber cup gland is tightened on valve cylindrical body (1) outside thread by six rib fasteners on rubber cup by rubber cup gland (3) spanner, with leading truck (6), valve body sealing surface (5), rubber cup gland (3) compact siro spinning technology is fixed.When oil drilling pump valve body is dismantled, by six rib fasteners on rubber cup gland (3) rubber cup gland (3) to be outwarded winding with spanner and unload, after rubber cup gland (3) is outwarded winding and is unloaded, rubber cup (4) is taken out, after rubber cup (4) takes out, complete with spanner valve body sealing surface (5) outwarded winding unmount.When oil drilling pump valve body is assembled, as long as valve body sealing surface (5) is tightened on valve cylindrical body (1) with spanner, by valve cylindrical body (1), rubber cup (4) is enclosed within valve body sealing surface (5), be tightened on by rubber cup gland (3) on valve body sealing surface (5) and rubber cup (4), assembling completes.Being easy to realize the dismounting of valve body, assembling, revolutionizing oil drilling pump valve body when changing valve body sealing surface and rubber cup, together with the problem that valve body is together scrapped.
With reference to accompanying drawing Fig. 1, on valve cylindrical body (1) top, be provided with four holes, groove is provided with, when taking out valve body, as long as hook taking carried out moving up and down finding groove on valve body top around hole, in groove, carry out circumference move, soon hanging hole is inserted in hook taking, above carry and valve body is taken out, overcome the problem that traditional valve body takes out difficulty.
