Coal water slurry pneumatic cement ball valve fault alarm ⑨ Quick connector: one end is connected to the solenoid valve or actuator, and the other end is directly inserted into the air pipe for use.
Application status and selection criteria of PTFE compensator
1. The compensator is usually installed on the thermal pipes such as hot water, steam, smoke and air, and gas to absorb the deformation caused by heating.
2. The outlet of the pump is suitable for metal soft connection (also called pneumatic butterfly valve). Since it is difficult to set a fixed support for the pipeline in the pump room, the compensator is easily damaged by the pipeline stretching at the pump port.
3. When selecting the type of compensator, the manufacturer shall be provided with the pipe diameter of the pipe, the temperature, pressure, compensation amount and other corresponding coefficients of the PTFE compensator medium. The manufacturer shall calculate the optimal design data to ensure the optimal service life of the compensator. The corrugated compensator is composed of the bellows (an elastic element) that constitutes its main body, end pipes, supports, flanges, conduits and other accessories. It is also called a contraction joint or expansion joint in custom. Due to its special material and use, it should be matched reasonably when selecting models, and understand various models. The detailed precautions for the tetrafluoro compensator are as follows: 1. The corrugated compensator is a disturbing element centered on the corrugated pipe, which can be used for axial, transverse and angular compensation on the pipeline.
2. In order to reduce the self-excited phenomenon of the medium, the PTFE compensator is equipped with an inner sleeve inside the product, which limits the radial compensation ability to a large extent, so it is generally only used to absorb or compensate the axial displacement of the pipeline (if a small amount of radial displacement is really required in the pipeline system, it can also absorb the combination of axial, angular and arbitrary displacement;
3. Pay attention to the hinge compensator, which is used together with two or three compensators (a single hinge compensator has no compensation ability) to absorb the transverse deformation in a single plane;
4. Universal hinge type compensator, used by two or three matching devices, can absorb three-dimensional deformation. Technical characteristics and application status of non-metallic contraction joints
