Description
Technical field
It the utility model is related to stop valve technical field, more particularly to a kind of multi-purpose double filtering stop valves.
Background technology
Stop valve is also known as pipe valve valve, belongs to forced seal formula valve, so when valve is closed, it is necessary to applies to flap and presses
Power, do not leaked with forced seal face.When medium is by entering valve below flap, the resistance that overcomes required for operating physical force is valve
The frictional force of bar and filler and the thrust as caused by the pressure of medium, the power of closing valve is bigger than the power of valve opening door, so valve rod
Diameter it is big, the failure of valve rod bending otherwise can occur.It is divided into three kinds by connected mode：Flange connection, screwed connection, welding
Connection.After the valve of self sealss occurs, the medium flow direction of stop valve just changes by entering valve pocket above flap, at this moment in medium pressure
Under power effect, the power of closing valve is small, and the power of valve opening door is big, and the diameter of valve rod can be reduced correspondingly.Meanwhile acted in medium
Under, the valve of this form is also tighter.China's valve " three change to " once provided, the flow direction of stop valve, without exception using from upper and
Under.When stop valve is opened, the Lift of flap, when being the 25%~30% of nominal diameter, flow has reached maximum, represents valve
Door reaches fully open position.The fully open position of stop valve, it should be determined by the stroke of flap.Existing stop valve structure is heavy, outer
Shape size and Lift is larger, required installing space is larger, position-limiting action is limited, open and close speed is slow, exists in water big
The rubbish and impurity of amount, use for a long time can block the stop valve, and often flow backwards, polluted-water, so we need
Want a new stop valve to solve the above problems, meet the needs of people.
