S-tube valves

Glasses plate is called the name of glasses plate because it looks like the appearance of glasses, in fact, glasses plate academic is and cutting ring matching wear-resistant plate. In the concrete pump truck, the spectacle plate and the cutting ring cooperate with each other, they mainly work with the rubber spring, through the pressure self-balancing and rubber spring automatic compensation gap, so that the floating cutting ring has a self-sealing effect, thus increasing the delivery pressure of the S pipe valve. s pipe can withstand tens of thousands of times of swing is by these two things, so, look very simple, in fact, the quality requirements are very high, in general In order to increase the service life of the eye plate a carbide structure will be used.

Eyeglass plate cutting ring installation doubts.

1, glasses plate installation when the final will be the installation surface of the hopper to eliminate clean and tidy, and clear relativity docking set without protrusion, not a transitional fit, easy to cause the eye plate itself deformation, and perhaps not eliminate the deformation of the eye plate itself.

2, when not disassembled S tube, must be in to ensure that the rubber shock absorber installation position no concrete and sediment. Otherwise it will cause the spectacle plate to find abnormal destruction, or even the spectacle plate to fall into the hopper.

3, after the installation of the cobalt plate cutting ring, should find no gap. Otherwise it will cause the cobalt plate cutting ring to find abnormal destruction, or even the cobalt plate falling into the hopper. Many textbook content is required to have a gap of 0.07-0.1MM is wrong, because the rubber shock absorber try to support the plate, glasses plate and cutting ring as tight as possible, the pre-destruction will be reduced.
