Abstract
The utility model relates to an improved corrosion resistant diaphragm valve which is characterized in that a convex spherical face-shaped diaphragm is designed to face the valve body, and the diaphragm is made of polytetrafluorethylene which is 0.5 to 2 mm. A liner made of fluorine plastic is arranged on the inner wall of the valve body. The utility model has the advantage of strong corrosion resistance, and the diaphragm can be used by more than six hundreds thousand times.
Description
The utility model belongs to the barrier film stopper, particularly a kind of corrosion resistant membrane valve.
Membrane valve be in pipeline in order to the flow of regulated fluid medium and the device of pressure, in pressure differential range allowable, also can cut off or the conducting flowing medium.This valve is by actuator, push rod, and barrier film and valve body are formed.Actuator has manually and pneumatic two kinds.Barrier film is rubber parts mostly, and what have is lined with rubber at valve interior wall.Because the corrosion resistance and the intensity of rubber are relatively poor, the using scope of existing membrane valve is very limited.
The purpose of this utility model provides a kind of suitable conveying and controls various acid, caustic corrosion and oxide isolation, does not have to leak the membrane valve of long service life.
The utility model is to adopt following technological approaches to realize.Adopt good material diaphragm and the valve body linings such as fluoroplastic of decay resistance, simultaneously diaphragm is changed shape by concave spherical surface and be protruding sphere, to improve the fatigue strength of diaphragm towards valve body.
Further describe the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment manual diaphragm valve schematic representation.
Fig. 2 is protruding sphere diaphragm schematic representation.
Fig. 3 is the A-A sectional view of Fig. 2.
As shown in Figure 1, the actuator of membrane valve is a manually operated type, promptly drives the connecting rod 4 at diaphragm 5 back sides by handwheel 1, manual rod 2, spool 3, and diaphragm 5 is moved up or down, carries out the opening and closing that valve is finished in throttling on the face of the weir of valve body 7.It at the topped thickness of the inwall of valve body 71 to 8 millimeter fluoroplastics lining.As F46, F40, F23, F24, F30, F3, polyvinylidene fluoride, polyvinylfluoride, soluble poly tetrafluoroethylene etc.; According to usage requirement, lining material also can use polyethylene, polypropylene, polystyrene or ABS engineering plastics.
Shown in Fig. 2,3, diaphragm 5 adopts the good polytetrafluoroethylmaterial material of decay resistance to make, diaphragm 5 has a protruding sphere 9 towards barrier film valve body 7, and the sealed muscle 8 of projection is arranged on the protruding sphere 9, and the connecting rod 4 of diaphragm 5 is fixed on the central boss at protruding sphere 9 back sides.Diaphragm thickness is 0.5 to 2 millimeter.
The utility model embodiment uses the result to show, valve body fluoroplastics lining and teflon diaphragm corrosion resistance are strong, be applicable to the adjusting control of fluids such as high viscosity suspended particulate fiber medium and poisonous medium, diaphragm reaches more than 600,000 times working life, is up to 930,000 times.
