进口气动高压切断阀美国阿卡迪亚品牌

进口气动高压切断阀Product description:

The following technical scheme is provided: an integrated pneumatic high-pressure cut-off valve, including a valve body, a valve seat and a valve core. The valve body is hollow and its axial ends are inlet and outlet respectively. The valve seat is arranged in the valve body near the outlet. The valve seat is provided with an active chamber that allows the valve core to move back and forth. The active chamber is sealed with the valve core. A block matching with the valve core is arranged between the valve seat and the outlet. The valve core is hollow and provided with a large channel, It also conflicts with the blocking block. The valve core and the valve body form an air pressure chamber. The air pressure chamber is divided into A chamber and B chamber which are not connected with each other through an annular barrier. The annular barrier is fixed on the valve core. The valve body is equipped with A chamber opening corresponding to A chamber and B chamber opening corresponding to B chamber. A chamber is equipped with a spring. The valve stem is canceled, and the valve core is driven by pressure, so that the whole valve body is set in one, reducing the risk of leakage.

characteristic:

The valve core can move relative to the valve seat, and collide with or separate from the blocking block. In case of conflict, the large channel is disconnected from the flow channel, and the medium cannot pass through. After separation, the large channel is connected with the flow channel, so that the medium passes through the inlet ? large channel ? flow channel ? outlet sequence. The valve stem in the existing technology is canceled, and the valve core moves through the pressure difference between chamber A and chamber B, The side with high pressure will push the annular spacer to move to the side with low pressure, so the valve body does not need to be equipped with a mounting hole for the valve stem, making the whole valve body integrated, reducing the risk of leakage; On the one hand, the spring set in cavity A provides corresponding force for the annular blocker through its conflict with the annular blocker, so that the valve core fits more closely with the blocker to avoid gaps between them; on the other hand, it can push the annular blocker to move the valve core to the blocker and conflict with it when the pressure in cavity B is less than that in cavity A, with reset effect and sensitivity.

Principle:

It includes the valve body, the valve seat and the valve core arranged in the valve body. The valve body is hollow and its axial ends are inlet and outlet respectively. The valve seat is arranged in the valve body near the outlet. The valve seat and the valve core are movably sealed. Between the valve seat and the outlet, there is a block block matching with the valve core to form a flow channel between the block block and the valve seat, The other end is connected with the flow channel and conflicts with the blocking block. The valve core and the valve body form an air pressure chamber, which is divided into A chamber and B chamber through an annular barrier
