This utility model discloses a plastic-coated steel pipe bend joint suitable for low-temperature conditions, comprising a bend section and straight pipe sections welded to both ends, forming a bend structure. It also includes: a stress buffer device comprising a corrugated compensator welded to the junction of the bend section and the straight pipe section, and a flow-damping orifice plate connected to the other end face of the corrugated compensator; and a damping sliding pair comprising a damping sliding tube fixed to the outer wall of the flow-damping orifice plate and a fixed damping kit fitted into the inner wall of the straight pipe section. The end face of the corrugated compensator connected to the flow-damping orifice plate is a free end that slides axially along the straight pipe section, and the damping sliding tube and the fixed damping kit achieve a sliding seal through an elastic seal. This utility model uses the sealing gas, the elastic material in the corrugated compensator, and the friction generated by the relative sliding of the damping sliding tube and the fixed damping kit to jointly counteract the pressure caused by frost heave, making the joint fully adaptable to low-temperature conditions.

The utility model discloses a power plant energy -saving type cyclone, including cyclone main part, the left side intercommunication of cyclone main part has the inlet pipe, and the right side intercommunication has the overflow pipe, the bottom of cyclone main part is provided with the underflow port. The utility model discloses through the first pivot and the second pivot staggered distribution's rubbing rod in the processing box, under the driving of drive motor, can carry out rubbing to the larger particle in the material of entering the processing box, avoids the larger particle to cause the jam after entering cyclone main part, has guaranteed the normal operation of cyclone, has improved separation efficiency, has reduced the energy that stops and clears up because of jamming and consumes, has reached the purpose that saves energy, the setting of vibrating sieve plate can carry out the preliminary screening to material, and the larger particle will be intercepted on the sieve plate, and along the sieve plate from the discharge slot of inclination is discharged, and the larger particle is conveniently handled or recycled, and the processing effect of material is further improved.

The application relates to a commercial vehicle cab front protection structure and belongs to the technical field of vehicle safety protection. The protection fence comprises a head-on collision area and a side collision area, the head-on collision area is used for being connected with a front cross beam of a vehicle frame, and the side collision area is located on the two sides of the head-on collision area; a column piece is connected on the side collision area of the protection fence, one side of the column piece is provided as a fixed surface, and the other side is provided as an anti-collision reinforcing surface; a connecting assembly is connected at one end with the fixed surface and at the other end with the front cross beam of the vehicle frame. The column piece and the protection fence are connected on the front cross beam of the vehicle frame, and the head-on collision area and the side collision area of the protection fence and the anti-collision reinforcing surface of the column piece can resist impact, so that the cab can be well protected when the vehicle collides frontally or laterally.
