The price of the industrial filling pump eyeglass plate cutting ring for filling industrial pump accessories includes the eyeglass plate, cutting ring, rubber spring, shaped nut, transition sleeve, seal, large and small bearings, and S-pipe welding body, which constitute the S-pipe valve.

And the eyeglass plate and cutting ring mainly play the following roles:

Sealing function: They mainly work in conjunction with rubber springs, and through pressure self balancing and automatic compensation of gaps by rubber springs, the floating cutting ring has a self sealing effect, thereby increasing the delivery pressure of the S-pipe valve.

Cost reducing effect: Due to the action of the eyeglass plate and cutting ring, they replace the wear between the feeding port and the material cylinder, protecting the service life of both.

Their working principle is that under the pre tightening force of the unfolded nut, the rubber spring is compressed, and the cutting ring is tightly attached to the eyeglass plate. The cutting ring and the eyeglass plate belong to relative motion coupling components. After wear occurs, the rubber spring can compensate for the wear of the eyeglass plate and the cutting ring by relying on its own elasticity, eliminating the wear gap. When the wear of the cutting ring reaches a certain level, the compression of the rubber spring is zero, and there is no pressing force on the cutting ring. The nut can be tightened and unfolded to pull the S-tube welded body back and restore the compression of the rubber spring. Then, the eyeglass plate and rubber spring are compressed tightly, and the gap is compensated. This method effectively ensures the sealing performance between the eyeglass plate and the cutting ring.
充填工业泵配件之工业充填泵眼镜板切割环价格眼镜板、切割环、橡胶弹簧、异形螺母、过渡套、密封件、大小轴承和S管焊接体构成了S管阀。

而眼镜板、切割环主要起到以下作用：

密封作用：它们主要和橡胶弹簧配合工作，通过压力自平衡和橡胶弹簧自动补偿间隙，使浮动的切割环具有自密封作用，从而增大S管阀的输送压力。

减少成本作用：由于眼镜板和切割环的作用，它们取代了进料口与料缸之间的磨损，保护了二者的使用寿命。

它们的工作原理是：在展开螺母预紧力的作用下，橡胶弹簧受压，便切割环与眼镜板紧密贴合。切割环与眼镜板属于相对运动耦合件，产生磨损后，橡胶弹簧可依靠自身的弹性开补偿眼镜板与切割环的磨损量，消除磨损间隙。当切割环的磨损达到一定程度，橡胶弹簧压缩量为零，对切割环无压紧力，可拧紧展开螺母，将S管焊接体往后拉紧，恢复橡胶弹簧的压缩量，便眼镜板与橡胶弹簧压紧，间隙得到补偿。这种方式很好的保证了眼镜板与切割环的密封性能。
