Abstract
The utility model provides an air bag sealing structure for a circular material conveying valve. The air bag sealing structure for the circular material conveying valve comprises a valve cover, a valve plate, a sealing ring and a sealing ring seat, wherein, the sealing ring is connected on the valve cover through the sealing ring seat, a metal inner lining ring is embedded in the sealing ring, a plurality of air charging holes are arranged along the periphery of the metal inner lining ring, and an air inlet hole is also arranged on the valve cover and connected with the air charging holes of the metal inner lining ring. The contacting surface of the valve plate and the sealing ring adopts a spherical surface. The air bag sealing structure for the circular material conveying valve has the advantages that the valve plate and the sealing ring are not contacted during the opening and closing processes, the opening and closing torque is small, and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, especially a kind of air sac sealing structure of circular material transfer valve.
Background technology
The valve of material pneumatic conveying system use at present, the general ball-valve structure that adopts rubber and spheroid soft seal, rubber seal is close on the spheroid by initial tension of spring, hoisting capacity is big in opening-closing process, be prone to material stream passed jam phenomenon, damage rubber seal easily, cause the inefficacy of valve.
Summary of the invention
Big in order to overcome existing material pneumatic conveying system valve opening and closing moment, be prone to material stream passed jam phenomenon, damage the deficiency of rubber seal easily, the utility model provides a kind of air sac sealing structure of circular material transfer valve.
The technical scheme that its technical matters that solves the utility model adopts is a kind of air sac sealing structure of circular material transfer valve, comprise valve gap, valve plate, seal ring, packing holder, seal ring is fixed on the valve gap by packing holder, stud with the metal inner lining circle in the seal ring, metal inner lining circle upper edge circumference has a plurality of qi of chong channel ascending adversely hole, also have an induction opening on the valve gap, communicate with the qi of chong channel ascending adversely hole of metal inner lining circle.Valve plate and seal ring contact surface are sphere.
The beneficial effects of the utility model are valve plate and seal ring no touch in opening-closing process, and keying moment is little, have prolonged the service life of valve.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the constructional drawing of present embodiment
Among the figure: 1. induction opening; 2. valve gap; 3. packing holder; 4. metal inner lining circle; 5. qi of chong channel ascending adversely hole; 6. valve plate; 7. seal ring.
The specific embodiment
As shown in Figure 1, a kind of air sac sealing structure of circular material transfer valve, comprise valve gap 2, valve plate 6, seal ring 7, packing holder 3, seal ring 7 is fixed on the valve gap 2 by packing holder 3, stud with metal inner lining circle 4 in the seal ring 7, metal inner lining circle 4 upper edge circumference have a plurality of qi of chong channel ascending adversely hole, also have an induction opening 1 on the valve gap 2, communicate with the qi of chong channel ascending adversely hole 5 of metal inner lining circle 4.Valve plate 6 is a sphere with seal ring 7 contact surfaces.When valve plate 6 was in the closed position, high pressure gas were entered in the seal ring 7 by the qi of chong channel ascending adversely hole 5 on the metal inner lining circle 4 by induction opening 1, were close on the valve plate 6 after seal ring 7 is expanded, and played sealing function.When wanting Open valve, seal ring 7 loses heart, and makes and throws off back rotary valve plate 6 on seal ring 7 and the valve plate 6, does not have friction in the opening-closing process, and keying moment is little, has effectively protected seal ring 7.
Claims (2)
1, a kind of air sac sealing structure of circular material transfer valve, comprise valve gap, valve plate, seal ring, packing holder, seal ring is fixed on the valve gap by packing holder, it is characterized in that: stud with the metal inner lining circle in the described seal ring, metal inner lining circle upper edge circumference has a plurality of qi of chong channel ascending adversely hole, on described valve gap, also have an induction opening, communicate with the qi of chong channel ascending adversely hole of metal inner lining circle.
2, the air sac sealing structure of circular material transfer valve according to claim 1 is characterized in that: described valve plate and seal ring contact surface are sphere.
