Cooling controllable system for polyurethane balloon forming equipment

Abstract

The invention discloses a cooling controllable system for polyurethane balloon forming equipment. The cooling controllable system comprises a circulating cooling device, an adjustable multi-way diverter valve, a control monitoring unit, a flow sensor, a temperature sensor, a first electric switch valve, a cooling pump, a mold with a thermal load and a pipeline, wherein the flow sensor, the temperature sensor, the first electric switch valve and the cooling pump are arranged on each branch; according to the technical scheme, the cooling controllable system adopts the adjustable multi-way diverter valve to distribute the coolant to each branch, and the flow of the coolant on the branch is increased by using the cooling pump; meanwhile, a first electric switch valve is used for controlling the on-off of a cooling flow channel arranged in the mold, so that a coolant can be independently provided for each device in a one-to-one correspondence manner; meanwhile, the cooling agent is distributed according to the cooling requirement of each mold by utilizing the adjustable multi-path flow dividing valve, so that a cooling management system of a plurality of forming devices is established, and the utilization rate of the cooling agent is greatly improved.

Description

technical field [0001] The invention relates to the technical field of balloon molding equipment, in particular to a cooling controllable system for polyurethane balloon molding equipment. Background technique [0002] Balloon catheter is a key device for the dredging of human blood vessels, trachea, esophagus and intestinal tract, as well as widely used stent delivery; among them, in cardiovascular interventional surgery, the balloon catheter can be directly expanded and expanded at the stenosis of blood vessels The stent can also be sent to the stenosis of the blood vessel with the help of a guiding catheter and a balloon catheter, and then the balloon is expanded to open the stent pressed on the balloon, and the stent is embedded in the inner wall of the blood vessel, so as to restore the narrowed blood vessel. Normal size to ensure smooth blood flow; with the development of medical level, medical catheters play a more important role in clinical medicine, and balloons, as...
