NOVELTY - The utility model claims a stainless steel clamp check valve, comprising a stainless steel clamp check valve main body, two ends of the stainless steel clamp check valve main body are fixedly connected with a connecting pipe through a flange, the inner part of the connecting pipe is provided with a mounting pipe, one end of the mounting pipe is provided with a connecting port; The utility model is provided with a mounting pipe, so when the connecting pipeline and the stainless steel clamp check valve main body are connected, the graphene block and the sleeve rod will be propped against the outer side wall of the connecting pipeline due to the force, reset spring that the electric heating block is heated so as to make the temperature in the connecting pipeline rise, This not only effectively avoids the problem that when the device is used by the environment with low temperature, the phenomenon of freezing can happen so as to cause blockage, at the same time, it can heat the connecting pipeline with different sizes, so as to improve the practicability and convenience.
