Description
Technical field
This utility model is related to a kind of stop valve, more particularly, to new no hydrops stop valve.
Background technology
The opening and closing element of stop valve is fan-shaped flap, and sealing surface is in plane or the conical surface, and flap is made directly along the centrage of fluid
Line moves.The forms of motion of valve rod, has elevating lever-type (valve rod lift, handwheel do not lift), also have lifting rotation rod-type (handwheel with
Valve rod rotation and lifting together, nut is located on valve body).Stop valve is only applicable to standard-sized sheet and fully closed, does not allow to make adjustments and throttle.
Stop valve belongs to forced seal formula valve, so in valve closing it is necessary to apply pressure to flap, not let out with forced seal face
Leakage.When entering valve pocket below medium is by flap, the resistance overcoming required for operating physical force, be valve rod and filler frictional force with by
Thrust produced by the pressure of medium, the power of closing valve is bigger than the power of valve opening door, so the diameter of valve rod is big, otherwise can occur
The fault of valve rod bending.In recent years, after the valve of sealing occurs, the medium flow direction of stop valve just changes by entrance above flap
Valve pocket, the valve of this form is also relatively tighter.China's valve " three change to " once specified：The flow direction of stop valve, without exception using certainly
Upper and under.Stop valve open when, the Lift of flap, be nominal diameter 25%-30% when, flow has been maxed out,
Represent that valve has reached fully open position.So the fully open position of stop valve, should be determined by the stroke of flap, rely on valve rod pressure,
So that valve clack sealing surface is fitted tightly with sealing surface of seat, stop flow of media.Require according to pharmaceutical industry GMP standard, new nothing
Hydrops antibiotic stop valve valve not only will have good sealing property, and to strict demand is also had on encapsulant.From material
Higher temperature, pressure be can adapt on matter；Operationally medium is not subject to shadow to erosion, corrosion and the abrasion of valve seal material
Ring, can guarantee that valve not permeable in validity period (letting out) reveals.We start with from the internal structure design of valve at emphasis, and improving constantly should
Economy benefit resolutely with unit.Antibiotic stop valve modern science and technology, advanced technologies research and development can adapt to fermentation industry completely and want
The new product asked, produces the industry more preferable valve products of offer for meeting pharmacy, food and drink, chemical industry etc..
