The globe valve is divided into right angle type, straight type and direct current type according to the structure of the valve body.1, right-angle fluid only need to change the direction, so that the pressure drop through the valve than the conventional structure of the cut-off valve.

The globe valve is divided into right angle type, straight type and direct current type according to the structure of the valve body.1, right-angle fluid only need to change the direction, so that the pressure drop through the valve than the conventional structure of the cut-off valve. The valve body is mostly forged, suitable for smaller pass through, the higher pressure of the cut-off valve.2, straight-through type is the most common structure, the media import and export channels in the same direction was 180 °, but the fluid resistance of the largest.3, DC or Y-Type Forged Steel Globe Valve, the valve body flow channel and the main channel into a slash, the fluid resistance is small, and more for solid particles or large viscosity of the fluid.

Cut-off valve, also known as cut-off valve, are mandatory sealed valve

When the types of globe valves is closed, pressure must be applied to the flap to force the sealing surface from leakage.

When the types of globe valves is closed, pressure must be applied to the flap to force the sealing surface from leakage. When the medium from the bottom of the valve into the valve, the operating force to overcome the resistance is the stem and packing friction and pressure generated by the pressure of the valve, close the valve force than the valve, so the stem Of the diameter to be large, otherwise there will be stem stem bending failure. According to the connection is divided into three types: flange connection, threaded connection, welding connection. From the self-sealing valve appears, the valve out of the valve flow will be changed from the top of the valve into the valve chamber, then under the action of the media pressure, close the valve force is small, and open the valve force, stem diameter can be corresponding To reduce. At the same time, in the role of the media, this form of the valve is also more tight. China's valve "three to" has been provided, the flow of the valve, all from top to bottom. When the valve is opened, the opening height of the valve is 25% ~ 30% of the nominal diameter, and the flow has reached the maximum, indicating that the valve has reached the full position. So the full stop position of the cut-off valve should be determined by the stroke of the valve. View Details
