Description
Technical field
The utility model relates to shut-off valve technical field more particularly to a kind of new antibiotic shut-off valves.
Background technique
The opening and closing element of shut-off valve is the flap of stopper, and sealing surface is in plane or the conical surface, and flap is made straight along the center line of fluid
Line movement.The forms of motion of valve rod has elevating lever-type (valve rod lifting, handwheel do not go up and down), also have lifting rotation rod-type (handwheel with
Rotation and lifting, nut are located on valve body bracket valve rod together).Shut-off valve is only applicable to standard-sized sheet and Quan Guan, do not allow to make adjustments and
Throttling.Shut-off valve belongs to forced seal formula valve, so when valve is closed, it is necessary to apply pressure to flap, with forced seal
Face does not leak.When medium is by entering valve chamber below flap, the resistance overcome required for operating force, is the friction of valve rod and filler
Power 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 the diameter of valve rod is big, otherwise
The failure of valve rod bending can occur.In recent years, after the appearance of the valve of self-sealing, the medium flow direction of shut-off valve just changes by flap
The valve that side enters valve chamber kind form is also relatively tight.China's valve " three changes are given " once provides, the flow direction of shut-off valve, without exception using certainly
Under above.When shut-off valve is opened, the Lift of flap, when being the 25%~30% of nominal diameter, flow has reached maximum, table
Show that valve has reached fully open position.So the fully open position of shut-off valve, should be determined by the stroke of flap, by valve rod pressure, be made
Valve clack sealing surface is fitted closely with sealing surface of seat, prevents flow of media.
According to pharmaceutical industry GMP standard requirements, valve design and quality comply fully with pharmaceutical industry GMP standard (Q/
WJF01-2002 it is required as defined in), novel no hydrops antibiotic stop valve will not only have good sealing performance, but also to sealing
Also there is strict demand on material.It can adapt to higher temperature, pressure from material；Medium is to valve seal material at work
Erosion, corrosion and abrasion are unaffected, can guarantee that valve not permeable in validity period (letting out) reveals.There are flow resistances for existing shut-off valve
The problems such as power is big and inside is easily contaminated, therefore it is proposed that a kind of new antibiotic shut-off valve.
