Embodiment Construction
[0016] The present invention will be described in more detail below in conjunction with the accompanying drawings.
[0017] As shown in the accompanying drawings, a sealing member suitable for a flow pusher includes a sealing tube 1, a fastening ring 2, a clamp 3, a clamp 2 4 and a spring 5, and is characterized in that: the sealing tube 1 A sealing cavity 6 and a card groove 7 are arranged on the top, and a sealing strip 8 is arranged on the inner wall of the sealing tube 1. The sealing strip 8 is set in a wave-shaped structure, and the sealing tube 1 is set as a polymer rubber material. To facilitate the processing of the sealed tube 1, a sealed cavity 6 is provided on the sealed tube 1, and cooling liquid is added into the sealed cavity 6 to prevent the temperature of the flow maker from being too high and affect the service life of the seal. A plurality of sealing strips 8 improve the sealing performance between the sealing tube 1 and the pusher, the fastening ring 2 is se...

The invention discloses a sealing piece suitable for a flow pushing device. The sealing piece comprises a sealing pipe, a fastening ring, a first clamp, a second clamp and springs. The sealing piece is characterized in that the sealing pipe is provided with a sealing cavity and a clamping groove, sealing strips are arranged on the inner wall of the sealing pipe, and the fastening ring is arranged in the clamping groove; and the first clamp is arranged at the end, close to the fastening ring, of the sealing pipe, the second clamp is arranged at the other end of the sealing pipe, and the first clamp and the second clamp are both provided with fastening plates. The sealing pipe is provided with the sealing cavity, cooling liquid is added in the sealing cavity, and it is avoided that due to the over high temperature of the flow pushing device, the service life of the sealing piece is affected; the multiple sealing strips are arranged on the inner wall of the sealing pipe, and the sealing performance between the sealing pipe and the flow pushing device is improved; and the springs are arranged outside the sealing pipe, the springs are prevented from making contact with dirt water in the flow pushing device, the springs are prevented from being oxidized and corroded, and the service life of the sealing piece is further prolonged.
Description
technical field [0001] The invention relates to a seal, in particular to a seal suitable for a flow pusher. Background technique [0002] At present, the pusher is one of the indispensable equipment in the sewage treatment plant. There are various media of sewage in the sewage treatment plant. When the sewage of different media passes through the pusher, there are different requirements for the seal of the pusher. In the existing pusher seals, the spring of the seal often comes into contact with the sewage, causing the spring to be oxidized and corroded, resulting in a decrease in the seal between the seal and the pusher, making the seal invalid and unable to work normally , shorten the service life of the seal, and even make the flow booster broken, which increases the cost. Meanwhile, the existing seal also has the problem of poor high temperature resistance. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of low seali...
