Air pressure controllable system for polyurethane balloon forming equipment

Abstract

The invention discloses an air pressure controllable system for polyurethane balloon forming equipment, an air pressure management device is composed of a plurality of air pressure control assemblies, and each air pressure control assembly comprises a reversing valve, an air storage tank, a switch valve, a quick interface and an adjustable regulating valve, a port A and a port B of the first reversing valve are respectively connected with an air storage tank, and a port A and a port B of the second reversing valve are respectively connected with the two air storage tanks. A port P of the second reversing valve is sequentially connected with the adjustable regulating valve and the quick connector in series; a plurality of polyurethane balloon forming devices can be supplied with air by one air source device, so that accurate and efficient compressed air is provided for the forming devices, an integral air pressure controllable management system is established, the compressed air with different air pressures can be provided for a plurality of devices together, and the air can be accurately supplied to a single device; other settings are not needed, convenience and simplicity are achieved, the requirement for maintenance personnel is reduced, and the maintenance cost is low.

Description

technical field [0001] The invention relates to the technical field of air pressure control, in particular to an air pressure controllable system for polyurethane balloon molding equipment. Background technique [0002] Balloon catheters are the key equipment used to dredge human blood vessels, trachea, esophagus and intestines, as well as widely used stent delivery, and the balloon is the most critical part on the balloon catheter; the balloon generally requires extremely high resistance Blasting performance requires thin walls, softness, and foldability; to meet these requirements, not only the polymer materials used are required to have extremely strong mechanical and physical properties, but also high requirements are placed on the molding process; in order to meet the process requirements, molding equipment Heating, pressurization, and a wide range of speed and displacement adjustment must be provided accurately and efficiently, as well as accurate temperature and press...

AI Technical Summary

Problems solved by technology

[0003] The existing polyurethane balloon molding equipment is used with one equipment and one compressor, which can provide accurate and efficient compressed gas for the molding equipment; but the investment in production equipment is high, and the installation, maintenance and management of equipment Responsible and cumbersome
