The process of axial high temperature compensator and the composition of sleeve compensator
2023-09-23
The axial high temperature compensator can compensate for the axial deformation of the high temperature pipeline. When the metal material cannot solve the problem fundamentally, the method of heat insulation can be used.Fill in temperature-resistant insulation materials of different thicknesses between the diversion tube and the bellows to avoid direct contact with the bellows by the high-temperature medium, so that the heat of the medium is slowly transmitted to the bellows. At the same time, natural or artificial cooling measures are taken outside the expansion joint to make the actual temperature of the bellows lower than the allowable temperature of the bellows material.It is also possible to continuously pass steam or air with low temperature between the diversion tube and the bellows.A gas layer is formed between the two, which brings the heat to be transmitted to the bellows into the pipe and acts as heat insulation.
The sleeve compensator consists of an inner and outer sleeve capable of axial relative movement.Packing letters are used to seal the inner and outer sleeves.Keep the pipes at both ends moving on an axis when in use.The products are mainly composed of sleeves (core tube), housings, sealing materials, etc.It is used to compensate for the axial expansion and contraction of the pipeline and the axial rotation at any angle.It has the characteristics of small size and large compensation amount. It is suitable for hot water, steam, and grease media. Through the sliding movement of the sliding sleeve to the outer sleeve, the compensation for thermal expansion is achieved.
The inner sleeve of the sleeve compensator is connected to the pipe, and adopts the principle and structure of self-compression dynamic sealing. It can slide freely in the shell with the expansion and contraction of the pipe, and can adapt to the sealing requirements of any pipe.A new type of synthetic material is used to seal between the shell and the inner sleeve, and the applicable temperature is -40 to 150, and in some cases it can reach 350.It can not only slide axially, but also the medium in the tube does not leak.
