What role do the glasses plate and cutting ring play? Let us understand

Issue Time:2021-03-29
1. Reduce the cost of use. It replaces the wear between the S valve feed port and the feed port of the cylinder with the wear between the eye plate and the cutting ring. In this way, the cost of replacing a set of eye plate and cutting ring is much lower than the cost of replacing the S valve and the material cylinder. 2. Improve the sealing performance. Because there is a rubber compression ring between the cutting ring and the S valve, it acts as the cutting ring to give the eye plate a pre-pressure, thereby improving the sealing performance between the cutting ring and the eye plate. 3. It has a cutting effect on the aggregate between the cutting ring and the eye plate of the concrete pump truck, so as to ensure the correct position between the cutting ring and the eye plate.

Glasses plate, cutting ring, rubber spring, special-shaped nut, transition sleeve, seal, big and small bearing and S-tube welded body constitute the S-tube valve. The glasses plate and cutting ring of the concrete pump truck mainly play the following functions: Sealing function: They mainly work with rubber springs, and the gap is automatically compensated through pressure self-balancing and rubber springs, so that the floating cutting ring has a self-sealing effect, thereby increasing The delivery pressure of the S pipe valve.
