When the rotating shaft 41 is actuated to rotate, the sleeve 31 and the rotating shaft 41 are tightly sleeved. Therefore, the shaft 31 and the shaft connected to the sleeve 31 can be simultaneously linked by the rotation of the rotating shaft 4 The components such as the cymbal, the =rotating ring 332, the first-stage sealing assembly 34, the second rotating ring 391, and the feeding ring 38 are synchronously rotated, and have a firm force in the process side A of the mechanical device 4 to ensure mechanical damage. 4 The seal leakage prevention effect is achieved when the liquid is transferred. In addition, because the conveyor ring 38 1% rotates with the rotation shaft 41 together with the second rotation ring 391, the guide grooves are disposed on the outer peripheral wall (10) of the conveyor ring 38. It will exert a continuous plucking effect on the insulating liquid, forcing the insulating liquid to accelerate the flow and guiding the insulating liquid to be naturally and smoothly introduced by the first insulating liquid circulation mouth, and discharged by the second insulating liquid circulation port 364, so that it is not needed In addition to the additional pressure of the isolation fluid, the excellent cooling #ring effect can be achieved, and the toxic fluid on the process side can be effectively isolated. Specifically, when the rotating shaft 41 rotates at a high speed, the card type double shaft seal 3 is generated; the offset phenomenon occurs, and the second body is used to define the inner wall of the channel 361 near the atmosphere side. The recessed space is formed at 8 places, and the space for the second stationary ring 392 to be displaced is provided to prevent the second stationary ring 392 from being damaged by rubbing the second body 36 for a long time, thereby prolonging the service life of the component. Furthermore, the cartridge type double shaft seal 3 of the present invention is designed to be combined with the first seat ring to form a first stationary ring 333 by means of 11 201100676, which not only increases the transmission time. The stability, and can reduce the number of transmission components, reduce unnecessary interference, and can increase the pendulum of the first stationary ring 333 without deformation problems. In addition, the first stationary ring 333 of the embodiment is a body-shaped forming, and the first abutting ring and the first seat ring are combined in a pressing manner compared with the conventional one, and there is no secondary seal or elastic element between the two components. 'If it is used at high temperature and high speed or for a long time, breakage (4) will occur; therefore, the strength of the first stationary ring 333 of the present embodiment is much larger than that of the conventional first abutment ring, and the service life can be greatly improved. Referring to Fig. 5' is a second preferred embodiment of the dicing double (4) 3 of the present invention. The second preferred embodiment is substantially identical to the first preferred embodiment, wherein the #th yoke example is not suitable for general use. The sealed cavity a space is called, and the second preferred embodiment is applicable to the large sealed cavity 43 space (bigb〇red) mechanical device 4, and the second preferred embodiment further includes The accompanying sample q 0 in the valley hole 3 51 of the first body 35, the second order *35= etc. described above: the:: holding ring 3. - the facet is defined as the view angle relationship is not displayed. = =; the coffee and the strict groove (35S) then placed on the second step of the retaining ring 30 is no longer the same as the above-described preferred embodiment Therefore, this == description. Further, in the present embodiment, the support # 372 has a contact with the second stop washer 371, and therefore, the support ring is directly formed on the first body to be in the form of a body. The ΦίΓΓ firstly inserts the compression ring 334 into the first body 35, and the piece 335 is placed in the retaining ring 30, and then the retaining 12 201100676 . & 3〇 is screwed to the inner wall of the first body. The compression ring 334, the first elastic piece 335, the retaining ring 3〇 and the first body % constitute the purpose of the integrated transmission assembly. Therefore, the personnel only need to remove the bolt 51 on the second body 36 during maintenance. The occlusion double shaft seal 3 is withdrawn from the rotating shaft 41, and the first body 35, 36 is disassembled, so that the first body 35, the retaining ring 30, the compression ring, and the first elastic member 335 are simultaneously separated, and In the process, the problem of looseness of the first elastic τ 片 335 will not be issued, and the module can be directly replaced - the component can be reused even without replacement, which not only saves the maintenance of the 〇 (4) '(4) can be large (four) provincial maintenance costs. Referring to Fig. 6 'the third preferred embodiment of the card g type double shaft seal 3 of the present invention, the A is the same as the previous embodiment, except that the outer peripheral surface of the end cover 3U of the sleeve μ is provided with " The spiral channel 31G is additionally provided on the end cover 311, and may be designed as shown in FIG. With the foregoing two designs of the preferred embodiment, the impurity particles generated during the scramble process can be rotated by the sleeve 31 while the spiral channel 310 is taken away from each other to prevent each The component is blocked, which leads to a better sealing and leak-stopping effect. In summary, the invention of the present invention can achieve a simplified transmission assembly by the above-mentioned structural design to avoid excessive interference of the components, and at the same time, it ensures more stable operation, so that no additional insulation is required. Under the condition of pressure, an excellent sealing effect can be achieved, thereby effectively isolating the toxic fluid of the process side A; in addition, the service life of the component can be extended, and the sealing and leakage prevention effect can be effectively improved, so that the present invention can be achieved. purpose.
