Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, a kind of resistivity, it comprises aligning assembly 1, short protection tube 2, short central joint 3, adaptive joint 4 of transferring, long protection tube 5, long center sub 6, short central connector cover 7, long center sub lid 8.Aligning assembly 1 is connected with the internal thread of short protection tube 2 by end external screw thread, the other end of short protection tube 2 is connected by the external screw thread of internal thread with short central joint 3, the other end of short central joint 3 is connected with the adaptive joint 4 of switching by circlip for shaft, the other end of adaptive joint 4 of transferring is connected by the internal thread of external screw thread with long protection tube 5, the other end of long protection tube 5 is connected by the external screw thread of internal thread with long center sub 6, the other end of long center sub 6 is connected by the internal thread of external screw thread with short protection tube 2, the other end of short protection tube 2 is connected with aligning assembly 1 by internal thread.Short central connector cover 7 is fixed on the outer wall of short central joint 3 by screw 17, and long center sub lid 8 is fixed on the outer wall of long center sub 6 by screw 17, jointly constitutes resistivity.
Aligning assembly 1 is placed on the two ends of resistivity, avoids the great cantilever design of resistivity, reduce resistivity and descend vibration level and vibration deformation in working order.
As shown in Figure 2, a kind of structure of aligning assembly, it comprises aligning rubber 13, rubber standoff 14, screw 15, support 16.As shown in Figure 3, circumferentially hexagon is made in the middle part of support 16, in order to reduce the difficulty of processing of aligning rubber 13, avoid aligning rubber 13 to be directly installed on pressurized on support 16 and produce moderate finite deformation, affect the effectiveness in vibration suppression of aligning assembly, aligning rubber 13 is made rectangle, load in the slot of rubber standoff 14, hurt by rubber standoff 14 after aligning rubber 13 loads resistivity body compressive deformation, the edge designs of rubber standoff 14 has fillet, in order to ensure at-20 ° of C ~ 150 ° C, strong vibration, under shock environment condition, the effectiveness in vibration suppression of aligning assembly 1, according to resistivity body 12, aligning rubber 13, rubber standoff 14, the material thermal expansion coefficient of support 16, the rigidity of aligning rubber 13 and damping, rubber standoff 14 end face is lower than aligning rubber 13 more than end face 5mm, preferred 10mm.3 rubber standoff 14 are distributed on the radial position of support 16, rubber standoff 14 bottom design becomes the v-shaped openings of 120 degree of angles, coordinate with six prisms, two faces of support 16, bottom its V-shaped, cylindrical hole has been offered in axial centre position, and screw 15 is fixed on support 16 through the step cutting pattern hole of aligning rubber 13, the cylindrical hole of rubber standoff 14.As shown in Figure 4, aligning assembly 1 and resistivity body 12 lumen contact, achieve the resiliency supported between aligning assembly 1 and resistivity body 12 inner chamber, reach the object of resistivity vibration damping.The environmentally material of condition determination aligning rubber 13 and hardness.
As shown in Figure 5, short central connector cover 7 is fixed on short central joint 3 by 3 screws 17, short central connector cover 7 arc surface is shaped with 4 cylindrical bosses, lug boss position is positioned at the radial connector position be arranged on short central joint 3, as shown in Figure 6, each outer wall of boss offers annular radial sealed groove, avoid O RunddichtringO 9 to depart from from sealed groove when assembling, or according to end face seal form, dimensional tolerance is accumulative causes O RunddichtringO not contact with resistivity body 12, thus affects the risk of sealing effectiveness.Because ambient pressure is larger, one sealing ring is only adopted to be difficult to meet instructions for use, but resistivity body 12 radial direction limited space, radial dimension only enough installs the space of single track O RunddichtringO, therefore in order to realize the effective sealing of 4 cylindrical boss positions, short central connector cover 7 arc surface placed 2 rectangle grooves, as shown in Figure 7, 4 cylindrical bosses drop in 2 rectangle frames completely, by O RunddichtringO 10, O RunddichtringO 11 is respectively charged in rectangle groove, realize the second between short central connector cover 7 and resistivity body 12, three seal structures.As shown in Figure 5, resistivity and resistivity body 12 radial direction are connected by screw 18, make the lumen contact of 3 seal structures on short central connector cover 7 and resistivity body 12, and the elastic packing achieving resistivity tester connects.The environmentally material of condition determination sealing ring 9, sealing ring 10, sealing ring 11 and hardness.
The installation form of long center sub lid 8 and resistivity body 12, basically identical with the installation form of resistivity body 12 with short central connector cover 7, no longer elaborate here.
