Sealing structure for industrial machinery

[0014] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0015] see figure 1 , figure 1 It is a schematic diagram of the structure of the present invention.

[0016] An industrial mechanical seal structure includes a connecting plate 1, a positioning ring 2 is arranged inside the connecting plate 1, the contact surface between the positioning ring 2 and the connecting plate 1 is stepped, and the positioning ring 2 and the lower friction The plates 4 are in contact, and the lower friction plate 4 is in contact with the upper friction plate 5 , wherein the lower friction plate 4 and the upper friction plate 5 have the same diameter. The central position of the positioning ring 2 is provided with a rotating rod 3, the upper side of the upper friction plate 5 is connected with the moving ring 6, wherein the upper friction plate 5 is embedded in the moving ring 6, and the rotating rod 3 is connected with the moving ring 6. The locking nuts 8 are connected by threads, the upper side of the moving ring 6 is in contact with the tensioning spring 7 , and the upper end of the tensioning spring 7 is in contact with the locking nut 8 . When the present invention is in use, the positioning ring 2, the lower friction plate 4 and the upper friction plate 5 can be mutually tensioned by the tensioning spring 7, so as to achieve better sealing and meet the needs of industrial production.

[0017] In the description of the present invention, unless otherwise expressly specified and limited, the terms "installed", "connected", "connected" and "fixed" should be understood in a broad sense, for example, it may be a fixed connection or a detachable connection , or integrated; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of the two elements or the interaction relationship between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific situations.

[0018] The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the protection of the present invention. within the range.
