Abstract

Πρόκειται για την παραγωγή μιας βαλβίδας μείωσης της πίεσης για διαβρωτικά αιωρήματα, η οποία κάνει δυνατό ένα μεγαλύτερο χρόνο ηρεμίας και ταυτόχρονη καλύτερη συντήρηση. Σε μία βαλβίδα μειώσεως της πίεσης διαβρωτικών αιωρημάτων που αποτελείται από ένα θάλαμο βαλβίδας, από ένα τεμάχιο στραγγαλισμού από μία βελόνα ακροφυσίου και από ένα έδρανο βελόνας ακροφυσίου, ο θάλαμος βαλβίδας αποτελείται από ένα σφαιρικό περίβλημα (1) με ένα συνδεδεμένο κυλινδρικό περίβλημα στρα- γγαλισμού (2), όπου η βελόνα ακροφυσίου (3) εδράζεται στο σφαιρικό περίβλημα (1), κινητά κατά τη διεύθυνση του τεμαχίου στραγγαλισμού (5), ενώ η αιχμή (4) της βελόνας (3) διεισδύει από το σφαιρικό περίβλημα (1) μέσα στο κυλινδρικό περίβλημα στραγγαλισμού (2). Παρασκευή μιας βαλβίβας μείωσης της πίεσης για διαβρωτικά αιωρήματα. ωIt is the production of a pressure reducing valve for corrosive slurries, which enables a longer downtime and at the same time better maintenance. In a corrosive slurry pressure reducing valve consisting of a valve chamber, a nozzle needle throttle and a nozzle needle bearing, the valve chamber consists of a spherical housing (1) with an attached cylindrical throttle housing ( 2), where the nozzle needle (3) is seated in the spherical housing (1), movable in the direction of the choke piece (5), while the tip (4) of the needle (3) penetrates from the spherical housing (1) into the throttle cylinder housing (2). Preparation of a pressure reducing valve for corrosive suspensions. oh
