Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 and 2, the utility model provides a valve positioner shell, including last casing 1 and lower casing 2, it is equipped with embedded slot 3 to go up casing 1 oral area, 2 lateral walls of casing are equipped with inlet end 5 and give vent to anger end 6 down, 2 oral areas of casing are equipped with corresponding square inserted block 4 down, and when going up casing 1 and casing 2 down during the cooperation, insert square inserted block 4 in slot 3, can realize fixing between them, because inserted block and slot 3's length is great, frictional force between the two is great after the cooperation, is enough to realize fixing between the two, and for installation stability and the leakproofness that improve between casing 1 and the lower casing 2 square inserted block 4 outside parcel has silica gel layer 7, and silica gel layer 7's setting has further increased frictional force to sealed effect improves greatly. Another embodiment of the present solution is: as shown in fig. 4, the outside of the silica gel layer 7 is provided with a limit silica gel thorn 8, the inner wall of the slot 3 is provided with a corresponding reverse silica gel thorn 9, the thorn tip direction of the limit silica gel thorn 8 is towards the insertion direction, when the slot is inserted, the reverse silica gel thorn 9 and the limit silica gel thorn 8 are inserted, when the slot is pulled out reversely, the limit silica gel thorn 8 and the reverse silica gel thorn 9 are clamped with each other, the stability is improved, in addition, when the upper shell 1 and the lower shell 2 are required to be opened, the upper shell 1 and the lower shell 2 are forced to be pulled reversely by a pulling tool, at the moment, the limit silica gel thorn 8 and the reverse silica gel thorn 9 are deformed, the separation is realized, and by the structure, the sealing and installation stability of the device is greatly improved, the screw is not required to be reused, and the assembly is more convenient.
