Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-4, the compact type combined seal ring in this embodiment includes a seal ring 2, a first seal groove 3 and a pressure ball 5, the first seal groove 3 is formed on the seal ring 2, a pull block 6 is formed on two side walls of the first seal groove 3, the pressure ball 5 is bonded on one side of the pull block 6, a pull rope 7 is bonded below the pull block 6, the seal groove 3 and the second seal groove 4 are stably supported by the seal ring 2, so as to facilitate sealing of a connecting member, the pressure ball 5 is stably supported by the pull block 6, and the pull rope 7 is connected to facilitate connection of the pull rope 7, the pull block 6 is pulled by the pull rope 7, so that the pressure balls 5 on two sides are squeezed towards the middle to compress the seal ring 2 onto the connecting member, a metal ring 1 is bonded on the periphery of the seal ring 2, the metal ring 1 provides stable support for the seal.
