Product Description

J41W-16P flange globe valve 304 stainless steel flange globe valve plunger type high pressure industrial globe valve

 

Flange 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 to not leak. When the medium enters the valve six from below the disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the valve The diameter of the stem should be large, otherwise the valve stem will bend up failure. In recent years, since the emergence of self-sealing valves, the flow direction of the flanged globe valve has changed from above the valve disc into the valve cavity. At this time, under the action of the medium pressure, the force of closing the valve is small, while the force of opening the valve is large. The diameter of the rod can be reduced accordingly. At the same time, under the action of the medium, this type of valve is also tighter. my country's valve "Sanhua" once stipulated that the flow direction of the stop valve should be top-down.

 

When the shut-off valve is opened, when the opening height of the disc is 25%~30% of the nominal diameter, the flow has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the fully open position of the shut-off valve should be determined by the stroke of the valve disc. This type of valve should generally be installed horizontally in the pipeline.

Advantage
1. Simple structure, convenient manufacturing and maintenance.

2. The working stroke is small, and the opening and closing time is short.

3. Good sealing performance, small friction between the sealing surfaces, and long service life.

 

The disadvantages of the globe valve are as follows:

1. The fluid resistance is large, and the force required for opening and closing is large.

2. It is not suitable for media with particles, high viscosity and easy to coke.

3. Poor adjustment performance.

 

The types of globe valves are divided into external thread type and internal thread type according to the position of the valve stem thread. According to the flow direction of the medium, there are straight-through type, direct-flow type and angle type. The stop valve is divided into sealing form, there are packing sealing stop valve and bellows sealing stop valve.

 

The structure of the globe valve:

The structure of the globe valve body includes straight-through, direct-flow and right-angle. Straight-through is the most common structure, but its fluid resistance is the greatest. Direct flow fluid has low resistance and is mostly used for fluids containing solid particles or high viscosity. Right-angle valve bodies are mostly forged, which is suitable for shut-off valves with smaller passages and higher pressures.
