Main structural forms:

This valve is composed of parts such as valve body, rubber pipe sleeve, valve cover, etc.

Working principle:

When the control medium is not input, the cavity between the rubber pipe sleeve and the valve body is connected to the atmosphere, and the rubber sleeve is in an outward tension state under fluid pressure. Because there are reinforced curtain layers arranged at a certain angle inside the pipe sleeve, the axial direction of the pipe sleeve is affected

Balanced with radial pressure, the length and diameter of the pipe sleeve will not change due to fluid pressure. When the control medium enters the cavity between the pipe sleeve and the valve body, the rubber pipe sleeve deforms and intercepts flow under the pressure of the medium.

Installation and maintenance:

1. This valve can be installed freely on the pipeline without any restriction on the flow direction of the medium.

2. The maintenance cost of this valve is low, and only the rubber pipe sleeve needs to be replaced according to actual usage.
