Sleeve compensator commonly used in thermal pipeline use
Sleeve compensator commonly used in thermal pipeline use compensation volume, friction resistance is small sleeve compensator commonly used in thermal pipeline use, according to different characteristics of the classification. Henan Huanxin Xiaobian take you to know the classification way of sleeve compensator and the model. Classification according to its function and compression mode can be divided into the following: displacement compensation form can be divided into: one-way, two-way; packing compression mode can be divided into: ordinary type, injection filling type; restraint form can be divided into: unrestrained type, pressure balance type.
One-way sleeve compensator sealing structure using packing gland type, by the bolt to provide preload, sealed with sealing filler. In the structure is more suitable for hot water pipeline and the pressure is not high. In the occasion of higher pressure and higher temperature, it is easy to appear due to insufficient preload and lead to sleeve compensator leakage. Two-way sleeve compensator in one direction on the basis of the outer sleeve tube in both directions have expansion core tube, compensation volume for the ordinary twice, to achieve two-way compensation, the use of two ordinary type to reduce the length of the size and reduce the cost. Can be divided into ordinary compound and injection-filled compound two kinds. Injection-filled sleeve compensator consists of core tube, outer jacket tube, stuffing box, sealing filler, filling tube, etc. The stuffing box is filled with formed packing and non-formed flexible packing, so that the compensator can both relative axial sliding. Seal packing plays a leading role in sealing, when the seal for the purpose of maintenance work. Pressure-balanced sleeve compensator through the internal device to balance the pressure thrust, also called "no thrust" and do not balance the friction, in the calculation of fixed bracket thrust, divided into straight-through pressure type and bypass pressure type.
