Detailed Description

The following non-limiting detailed description of the present invention is provided in connection with the preferred embodiments and accompanying drawings. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a sealing device for slush pump, includes locating rack 1, and locating rack 1 top and bottom are close to outer edge and have all offered locating

hole

2, and 1 inside wall fixedly connected with sealing ring 3 of locating rack is convenient for connect with the flange of slush pump discharging pipe and discharge tube mouth department through setting up of locating hole 2, make sealing ring 3 fixed firm.

As shown in fig. 1, both ends of the outer side wall of the sealing ring 3 are provided with a limiting ring 4 and a positioning ring 5, and the outer diameter of the positioning ring 5 is smaller than that of the limiting ring 4, so that the limiting ring 4 can be tightly attached to the inner wall of the pipeline to be connected, and a good sealing effect is achieved.

The spacing ring 4 is corrosion-resistant rubber material, and the sealing ring 3 is high strength stainless steel material with locating rack 1, receives mud to erode, and difficult wearing and tearing, life are longer.

As shown in fig. 3 and 4, a plurality of keyway 6 has all been seted up at 3 lateral wall both ends of sealing ring, and a plurality of keyway 6 is annular evenly distributed, and the spacing ring 4 inner wall is provided with the protruding piece 7 with 6 one-to-one of a plurality of keyway, is convenient for install fast and fix a position spacing ring 4.

As shown in fig. 2 and 3, the outer side walls of the two ends of the sealing ring 3 are provided with the outer threads 8, the inner side wall of the positioning ring 5 is provided with the inner threads 9 corresponding to the outer threads 8, the outer side wall of the sealing ring 3 is in threaded connection with the inner side wall of the positioning ring 5, the thickness of the limiting ring 4 can be flexibly changed according to the inner diameter of the pipeline with the installation and connection, and therefore the inner wall of the pipeline can be tightly attached to the limiting ring 4 after installation, and sealing is convenient.

When the pipeline sealing device is used specifically, firstly, a user selects the limiting ring 4 with a proper outer diameter size to be sleeved at two ends of the outer part of the sealing ring 3 according to the inner diameter of a pipeline to be installed, and the positioning ring 5 is screwed to fix the position of the limiting ring 4.
