Abstract
The utility model provides a servomotor pressure-resisting sleeve seal assembly. The servomotor pressure-resisting sleeve seal assembly is arranged between a servomotor guide tube and a pressure-resisting sleeve and plays a seal role. The servomotor pressure-resisting sleeve seal assembly comprises an iron ring and a nylon gasket. One end of the pressure-resisting sleeve close to the servomotor guide tube is provided with the iron ring, and the nylon gasket is arranged between the iron ring and the inner side of the servomotor guide tube. The servomotor pressure-resisting sleeve seal assembly adopts the nylon gasket as main sealing material, and the iron ring structure is arranged to press the nylon gasket, deformation amount of the nylon gasket is larger that of an aluminum gasket, rigidity of the nylon gasket is larger than that of an O-shaped rubber ring, the nylon gasket has fine seal performances and has fine sealing effect in pressure resisting tests of an servomotor, and the test efficiency of the pressure resisting tests of the servomotor is improved.
Description
Technical field
The utility model relates to the transformation of hydraulic system sealing technique, relates in particular to a kind of servomotor pressure jacket black box.
Background technique
The speed regulator servomotor need carry out pressure test by means of pressure jacket after maintenance, as shown in Figure 1, the end face seal face out-of-flatness of existing speed regulator servomotor pilot sleeve, connecting screw hole is too little from the internal diameter distance, with the Sealing of withstand voltage sleeve, is generally aluminium pad 5.Because aluminium pad 5 is partially hard, in sealing place, the leakage of oil pressure release easily constantly occurs when carrying out pressure test, cause pressure not rise, pressure test is unsuccessful.
The model utility content
The utility model provides a kind of servomotor pressure jacket black box, to strengthen the sealing effect between pressure jacket and servomotor guide cylinder, improves the speed regulator servomotor and carry out the test efficiency of pressure test after maintenance.
For achieving the above object, the utility model provides a kind of servomotor pressure jacket black box, it is arranged between servomotor guide cylinder and pressure jacket, play seal action, described servomotor pressure jacket black box comprises iron hoop and nylon pad, described pressure jacket is provided with iron hoop near an end of described servomotor guide cylinder, and described nylon pad is arranged between the inner side surface of described iron hoop and described servomotor guide cylinder.
Further, the internal diameter of described iron hoop is identical with the internal diameter of described pressure jacket.
Further, described iron hoop welding is arranged at the end of described pressure jacket near described servomotor guide cylinder.
Compared with prior art, the utlity model has following beneficial effect:
The servomotor pressure jacket black box that the utility model provides has adopted nylon pad as main sealing material, and iron hoop structure is set to push down nylon pad, the deformation quantity of nylon pad is large than the aluminium pad, rigidity is strong than the rubber "O"-ring, there is very good sealability, can play good sealing effect when carrying out the pressure test of servomotor, the test efficiency of servomotor pressure test is provided.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
The structural representation that Fig. 1 is servomotor pressure jacket Sealing in prior art;
The structural representation of the servomotor pressure jacket black box that Fig. 2 provides for the utility model embodiment.
In Fig. 2,
1: the servomotor guide cylinder; 2: pressure jacket; 3: iron hoop; 4: nylon pad; 5: the aluminium pad.
Embodiment
Below in conjunction with the drawings and specific embodiments, the servomotor pressure jacket black box the utility model proposes is described in further detail.According to the following describes and claims, advantage of the present utility model and feature will be clearer.It should be noted that, accompanying drawing all adopts very the form of simplifying and all uses non-ratio accurately, only in order to convenient, aid illustration the utility model embodiment's purpose lucidly.
Core concept of the present utility model is, a kind of servomotor pressure jacket black box is provided, it is arranged between servomotor guide cylinder and pressure jacket, play seal action, described servomotor pressure jacket black box comprises iron hoop and nylon pad, described pressure jacket is provided with iron hoop near an end of described servomotor guide cylinder, described nylon pad is arranged between the inner side surface of described iron hoop and described servomotor guide cylinder, the servomotor pressure jacket black box that the utility model provides has adopted nylon pad as main sealing material, and iron hoop structure is set to push down nylon pad, the deformation quantity of nylon pad is large than the aluminium pad, rigidity is strong than the rubber "O"-ring, there is very good sealability, can when carrying out the pressure test of servomotor, play good sealing effect, the test efficiency of servomotor pressure test is provided.
Please refer to Fig. 2, the structural representation of the servomotor pressure jacket black box that Fig. 2 provides for the utility model embodiment.
As shown in Figure 2, the utility model embodiment provides a kind of servomotor pressure jacket black box, it is arranged between servomotor guide cylinder 1 and pressure jacket 2, play seal action, described servomotor pressure jacket black box comprises iron hoop 3 and nylon pad 4, described pressure jacket 2 is provided with iron hoop 3 near an end of described servomotor guide cylinder 1, and described nylon pad 4 is arranged between the inner side surface of described iron hoop 3 and described servomotor guide cylinder 1.
Further, the internal diameter of described iron hoop 3 is identical with the internal diameter of described pressure jacket 2.
Further, described iron hoop 3 welding are arranged at the end of described pressure jacket 2 near described servomotor guide cylinder 1.
The servomotor pressure jacket black box that the utility model embodiment provides has adopted nylon pad 4 as main sealing material, and iron hoop 3 structures are set to push down nylon pad 4, the deformation quantity of nylon pad 4 is large than the aluminium pad, rigidity is strong than the rubber "O"-ring, there is very good sealability, can play good sealing effect when carrying out the pressure test of servomotor, the test efficiency of servomotor pressure test is provided.
Obviously, those skilled in the art can carry out various changes and distortion and not break away from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model also is intended to comprise these changes and modification interior.
