球面关节

球面关节also called spherical compensator, mainly rely on angular displacement to absorb or compensate pipeline one or more directions laterial displacement, the compensator should be used in pairs, single spherical compensator has no compensation ability, can be used as universal joint.

它主要用于具有更高柔韧性的管道连接，球安装在球上以围绕环绕中心自由旋转，以便补偿热膨胀管，扭转ANS振动。它具有高补偿，小占用，较低的流体耐压，易于安装和低的优点。

电子型球形补偿接头的技术参数

Application Range

Spherical compensator is a kind of equipment for solving thermal expansion and contraction of pipelines. It can be widely used in metallurgy, petroleum, chemical, electric power, light industry, textile, construction and national defense construction industries.

The spherical compensator is mainly suitable for pipeline connection with large ground settlement, large vibration and complex terrain, and is installed on the pipe. The sphere can be freely rotated within the angle θ of the center of rotation to compensate for the deflection of the pipeline due to foundation settlement, thermal expansion and contraction. The utility model has the advantages of large compensation amount, small space occupation, small fluid resistance, convenient installation and low comprehensive cost.

Use Occasion

Spherical compensator is suitable for use on pipelines between factories and regional long distance transportation.

压力和膨胀后，高压管道具有有限的变形和位移，但空间有限。

Pipes requiring as low a pressure drop and turbulence as possible due to process operating conditions or economic considerations.

敏感设备的入口和出口管道对连接负载有一定限制。

在建筑物（建筑）与建筑物之间，由于浮桥引起的沉没或地震不均匀，管道的位置可能导致压力过载事故的可能性。

For pipelines with spherical compensators, the overall construction cost of the pipeline should be lower than that of other compensation methods.

Spherical compensator are available in a variety of configurations and are more flexible to use, but usually the main applications are two arrangements: one is to arrange two Spherical compensator fills on a horizontal or vertical Z-shaped pipe; the other is on a horizontal L-shaped pipe. Arrange three Spherical compensator supplements.

球面补偿器的特点：

1. Large compensation capacity, small occupation space, small fluid resistance and beautiful appearance (no filling nozzle).
2. 可以以任何角度围绕轴旋转，也可以在任何方向上弯曲，弯曲角度为±15°，共30°。
3. The sealing performance is good, the sealing material has large elasticity, low friction coefficient, good lubrication performance and small turning torque.
4. 由于补偿能力大，可达300米，可安排一组球补偿，因此固定括号较少，节省总投资和节约能源。
5. Can balance the blind force.
6. 可以实现通用的多维补偿，无论管道水平还是轴向补偿，其他任意方向都可以满足要求。
7. The price is one tenth of the import price.
8. 球通过CNC车床完成，具有高表面光洁度。
9. 球面补偿器具有大的补偿能力，这是传统方形补偿器的10倍。
10. 球面补偿器可以节省投资。
11. 球面补偿器可以减少热量损失和压力损失，节省能量。
