globe valve series-bb平台体育app官网

product description
the opening and closing part of the angle globe valve is a plug-shaped valve disc, the sealing surface is a plane or a conical surface, and the valve disc moves linearly along the center line of the fluid. angle globe valve, also known as angle valve, the movement form of the valve stem, there are lifting rod type (the valve stem rises and falls, the handwheel does not rise and fall), and there is also a lifting rotary rod type (the handwheel rotates and lifts together with the valve stem, and the nut is located in the valve body. superior).

angle type globe valve is only suitable for fully open and fully closed, no adjustment and throttling are allowed. the globe valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface of the globe valve not to leak. when the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the friction force between the valve stem and the packing and the thrust generated by the pressure of the medium. the force of the globe valve" is large, so the diameter of the valve stem should be large, otherwise the failure of the top of the valve stem will occur.

scope of application
angle globe valve is a commonly used cut-off valve, which is mainly used to connect or cut off the medium in the pipeline, and is generally not used to adjust the flow. globe valve products are suitable for a wide range of pressure and temperature, but are generally used for medium and small diameter pipelines, and are suitable for steam, oil, water and other media of ≤425°c.
