Product details

Product Introduction

The QJB type spherical compensator is composed of a shell, a sphere, a flange, and a sealing ring. During the working process, the sphere is nested inside the shell, and the two are sealed and connected by a rubber sealing ring. The sphere can rotate freely within a certain range during use, which can compensate for the angular displacement of the pipeline. Spherical compensator is a new member of the compensator family. Due to its excellent compensation pipeline's lateral and angular displacement, it has received unanimous praise from customers since its entry into the market. If used alone, it can be considered a universal compensation joint, usually used in boiler cooling systems. If only two combinations are used, it can achieve compensation for the lateral displacement of the pipeline, and its compensation amount is much larger than other general compensators. Good sealing performance and stable operation greatly reduce a large number of maintenance processes.



Product advantages

The QJB type spherical compensator is composed of a circular shell, a sphere, and a sealing ring. The shell contains a circular sphere with a sealing ring connected in the middle. In this way, the spherical compensator can freely achieve displacement compensation at various angles within the range of motion, which is suitable for pipelines with angular displacement and convenient for construction. The product is suitable for transporting media such as seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, finished oil, air, coal gas, steam and granular powder with a temperature not exceeding 250 degrees.


Product Features

The QJB spherical compensator has a large angular displacement compensation capacity and a long service life.

The QJB type spherical compensator has excellent material and stable operation.

The QJB type spherical compensator can effectively protect pipelines from adverse effects caused by subsidence.
