Background technology
Cryogenic globe valve refers to closure member, the valve that flap moves along valve seat center line.According to this mobile shape of flap
Formula, the change of valve seat port are and flap stroke direct proportionality.Because the valve rod of such valve is turned on and off stroke phase
To shorter, and there is very reliable cutting function, and the change due to valve seat port and the stroke of flap pass in direct ratio
System, is very suitable for the regulation to flow.Therefore, such valve is highly suitable as cutting off or adjusts and throttle and makes
With.
The valve rod axis of cryogenic globe valve are vertical with sealing surface of seat.It is relatively short that valve rod is turned on and off stroke, and has
There is very reliable cutoff action so that this valve is highly suitable as the cut-out or regulation and throttling use of medium.Low temperature
Stop valve is once in opening, just there is no contact between its valve seat and valve clack sealing surface, thus its sealing surface machine
Tool abrasion is smaller, need not be whole when being easier to repair or changed potted component due to the valve seat and flap of most of stop valve
Valve removes from pipeline, and this is very applicable for the integral occasion of valve and pipeline welding.Medium passes through such valve
Flow direction during door is changed, therefore the flow resistance of stop valve is higher than other valves.
Handwheel controls the switch of cryogenic globe valve by screw thread, and screw thread coordinates when receiving low temperature effect, easily produced low
Temperature extremely, poor durability.In the prior art, it is necessary to it is a kind of prevent handwheel low temperature extremely, improve durability sylphon seal knot
Structure cryogenic globe valve.
