Stainless steel globe valve can be divided into manual stainless steel globe valve, pneumatic stainless steelglobe valve, electric stainless steel globe valve. Stainless steel globe valve is a kind of material of globevalve, which has the characteristics of simple structure, good sealing performance and long service life.Generally applicable to pharmaceutical, chemical, shipbuilding, food machinery and other industries.Stainless steel globe valves can be divided into two categories according to the channel and thread position ofthe globe valve, and then subdivided.
According to the direction of the stop valve channel:
1. Straight-through globe valve
2. DC globe valve: In the DC or Y-shaped globe valve, the valve body flow channel and the main flow channel area diagonal line, so that the damage degree under the flow state is smaller than that of the conventional globevalve, so the pressure loss through the valve is also small. .
3. Angle globe valve: In the angle globe valve, the fluid only needs to change direction once, so that the pressure drop through the valve is smaller than that of the conventional globe valve.
4. Plunger type globe valve: In the plunger type globe valve, the valve disc and valve seat are usually designedbased on the plunger principle. The valve disc is polished so that the plunger is connected with the valve stem,and the sealing is realized by two elastic sealing rings sleeved on the plunger. The two elastomeric seals are separated by a collar and hold the seal around the plunger by the load applied to the bonnet by the bonnet nut.Elastomeric seals can be made from a variety of materials and can therefore be replaced.
Classification according to the thread position of the globe valve:
1. Upper threaded stem globe valve: the thread is outside the valve body. The valve stem is not eroded by themedium and is easy to lubricate. This structure is relatively common.
2. Lower threaded stem globe valve: the thread is in the valve body. The threads on the valve stem are in directcontact with the medium and are susceptible to erosion and cannot be lubricated. This structure is mostly used inplaces with small caliber and low temperature.
