Description
Technical Field
The invention relates to the technical field of PVC pipe processing, in particular to a safe bending mechanism used in the installation process of a PVC pipe.
Background
The PVC pipe is a plastic pipe which is formed by extrusion by a hot pressing method after polyvinyl chloride resin is matched with a stabilizer, a lubricant and the like, and is developed and applied at the earliest time. The PVC-U pipe has strong corrosion resistance, easy adhesion, low price and hard texture, but is only suitable for a water supply system with the conveying temperature not exceeding 45 ℃ due to the seepage of PVC-U monomer and additives. Plastic pipes are used for drainage, waste water, chemicals, heating and cooling liquids, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems.
PVC can be divided into soft PVC and hard PVC. The soft PVC is generally used for floors, ceilings and leather surfaces, but the soft PVC contains a plasticizer (which is a difference between the soft PVC and the hard PVC), and has poor physical properties (the soft PVC is not suitable for use if the water supply pipe needs to bear a certain water pressure), so that the use range of the soft PVC is limited. The hard PVC does not contain a plasticizer, so the hard PVC is easy to form and has good physical properties, thereby having great development and application values. In the production process of the polyvinyl chloride material, several auxiliary agents such as a stabilizer, a plasticizer and the like must be added, and if all the environmental-friendly auxiliary agents are adopted, the PVC pipe is also a nontoxic, tasteless and environment-friendly product.
At present, a PVC pipe and a pipe joint are installed through a hot melting technology, the arrangement and the steering of the pipeline are realized, the potential safety hazard can exist due to too many joints, the PVC pipe can be directly bent according to the situation when being used, if the pipe is bent, an elbow is not needed, one joint is used for reducing the potential safety hazard, the angle bending of the PVC pipe is directly carried out manually by a person, the great manpower is consumed, the bending angles are different, and the phenomenon that the pipe fitting is damaged due to the fact that the manual bending force of the person is uneven is easy to happen.
