CONNECTION FOR PRESSURE VESSELS' COVERS PACKING EQUIPPED WITH QUICK-CLOSING DEVICES

摘要

Solution with sealing located in the pressure tank flange groove, pressed in all phases of operation cycle to the flange of the cap of the quick-closing device by pressure exerted by working medium kept in the groove by sealing in required height, while all the safety standards for pressure tanks are followed.The overpressure in the sealing groove is ensured on the beginning of the pressuring of the pressure tank by feed of pressurized medium via tubing behind the closing armature on the inlet of the pressurized medium, and via tubing behind two or more closing armatures completed with regulating armatures on the inlet of the pressurized medium, where the parallel branches on the inlet of the pressurized medium are interconnected by means of one-way armature with flow of pressurized medium from the closing and regulating armatures with larger inner diameter, from the point between the closing and regulating armature towards closing and regulating armatures with smaller inner diameter. The leakage of pressure from the tubing to sealing groove into the pressure tank space is prevented by means of one-way armature in the circuit of tubing of overpressure in the groove for sealing after termination of pressuring by means of closing of the closing armature on the inlet of the pressurized medium by overpressure from the pressure tank space.<IMAGE>
