An electric heating constant-temperature barrel is fixedly connected to the bottom end of the inner side of a clamping supporting frame, extrusion electric push rods are clamped to the bottom end of the electric heating constant-temperature barrel, a closed supporting frame is clamped to the top ends of the multiple extrusion electric push rods, and a synchronous transmission box is clamped to the bottom end of the closed supporting frame; an output shaft of the synchronous transmission box is sleeved with a centrifugal separation sleeve, a centrifugal motor is installed at the position, located on the input shaft, of one end of the synchronous transmission box through a motor base, and a hollow protruding block is fixedly connected to the position, corresponding to the centrifugal separation sleeve, of the middle of the inner side of the electric heating constant-temperature barrel; the problems that in existing production, due to uneven feeding, uneven air inlet and insufficient external shaping, products are wrinkled, different in thickness and broken are solved, the production speed is increased, the production quality is guaranteed, the problem that in existing extrusion shaping, due to insufficient exhaust, extrusion protrusions or bursts, and defective products are generated is solved, and the production efficiency is improved. And the yield of products is further improved.

The utility model relates to the field of heat supply pipe network leak protection device, especially supply heat and heat with heat supply pipe network leak protection device. A kind of heat supply pipe network leak protection device for heating and heating, including fixed pipe, vice sleeve pipe, connecting pipe, rotating rod, guide rod and clamping block, fixed pipe is away from center end and is uniformly connected with vice sleeve pipe, two vice sleeve pipe insides are uniformly connected with connecting pipe, two connecting pipes are fixedly connected with fixed pipe, two connecting pipes are away from center end and are rotatably connected with rotating rod on two sides, four rotating rods are away from center end and are slidably connected with guide rod, four guide rods are close to center end and are fixedly connected with clamping block.The utility model is through the cooperation of fixed pipe, vice sleeve pipe, connecting pipe, prevents heat supply pipe network leakage, then through the cooperation of clamping block, connecting block and screw rod, it is fixed, finally through the cooperation of fixed round plate, plugging block and spring, effectively control the air pressure in pipeline, prevent pipeline from leaking due to excessive pressure.
