High pressure check valve, check valve

High pressure check Valve Product overview:

The high pressure check valve is a high temperature and high pressure self-sealing check valve composed of the valve body, valve seat, valve disc, rocker, sealing ring and valve cover, etc. The valve disc rotates around the valve shaft in the body cavity through the rocker. It is generally used in the thermal power plant high temperature and high pressure medium and the flow rate and pressure are relatively stable in the large caliber pipeline system. The valve depends on the flow of the medium on the valve disc, so that the medium flow in one direction, to prevent the medium backflow, the valve disc in the medium flow under the action of the thrust rotation open, in the absence of medium flow, the valve disc usually close to the seat to form a seal, the product opening and closing speed, high pressure, large diameter, smooth medium flow, fluid resistance is small.

High pressure check valve product advantages:

The cavity of the high pressure check valve adopts the pressure self-sealing structure. Before the pressure sealing, the three nuts are tightened to make the screw drive the compression ring to rise, and the pretension force is generated between the compression ring and the thrust ring and between the valve body and the thrust ring, forming the pretension specific pressure of the valve cover seal, so that the valve pressure can also be sealed when the pressure is low. When the pressure of the medium rises, the pressing ring moves upward under the action of the medium pressure, and the sealing specific pressure of the valve cover seal increases gradually with the increase of pressure. The Angle of the cone of the thrust ring is 30°, the Angle of the cone of the pressing ring is 31°, and the sealing surface of the two is in line contact.

The high pressure check valve is a high temperature and high pressure self-sealing check valve composed of the valve body, valve seat, valve disc, rocker, sealing ring and valve cover, etc. The valve disc rotates around the valve shaft in the body cavity through the rocker. It is generally used in the thermal power plant high temperature and high pressure medium and the flow rate and pressure are relatively stable in the large caliber pipeline system.
