Selection of Y-type globe valve:(1)Y-type globe valve is suitable for small-diameter pipelines to adjust the flow, pressure and accuracy requirements are not high or often closed to cut off the flow of one-way flow of the pipe section. (2) Due to the large resistance of the Y-type stop valve, it is relatively suitable for pipelines with low resistance requirements. (3) It is not suitable for media with high viscosity or containing particles that are easy to precipitate. Y-type globe valve, also known as "DC-type globe valve", Y-type globe valve stem and channel into a certain angle, the valve seat sealing surface and import and export channel also have a certain angle, the valve body can be made into a whole or separate. DC cut-off valve almost does not change the flow direction of the fluid, in
（1）YType A stop valve is suitable for small-diameter pipelines that need to adjust flow, pressure and precision requirements are not high or often close the unidirectional flow of cut-off water.
(2) BecauseYType cut-off valve has large resistance and is relatively suitable for pipelines with low requirements on convection resistance.
(3) It is not suitable for media with high viscosity or containing particles that are easy to precipitate.
Y-type globe valve is also called "DC-type globe valve",YThe valve stem and the channel into a certain angle, the valve seat sealing surface and the inlet and outlet channel also have a certain angle, the valve body can be made integral or separate. DC cut-off valve almost does not change the flow direction of the fluid, the minimum flow resistance in the cut-off valve. Valve seat and disc sealing surface can be surfacing carbide, so that the entire valve is more resistant to erosion and corrosion, very suitable for alumina system in the pipeline control, but also suitable for coking and solid particles in the pipeline.
Y type globe valve working principle:
Y-type globe valve can be straight-through and angle valve of the intermediate state. In order to change the straight-through tortuous fluid channel, the valve seat hole and the valve body are designed at a certain angle, so that the flow channel becomes more straight with the axis to reduce the pressure loss. This structure is popular in most applications and is widely used in steam systems. The solid conveying capacity has been greatly improved, but it needs to be carefully tested in use.
