A bracket base (3) on a bracket plate is hinged with one end of an air cylinder (4); a piston rod is hinged with one end of a connecting rod (6); the other end of the connecting rod (6) is fixedly connected with the upper end of a rotating shaft (7); the rotating shaft (7) is fixedly connected with one end of a rotating arm (8); the other end of the rotating arm (8) is provided with a vertical support bush; the upper end and the lower end of the support bush are respectively dynamically matched with shaft cores of an upper valve plate (9) and a lower valve plate (10); a lower static ring (18) is arranged between an upper valve cap (1) and the rotating shaft (7) and connected with the upper valve cap; an upper cover (17) is connected with the upper valve cap (1); an upper static ring (19) is arranged between the upper cover (17) and the rotating shaft (7) and connected with the upper cover; an upper dynamic ring (15) and a lower static ring (14) are sleeved on the rotating shaft (7); O-shaped seal rings are arranged among the upper static ring, the lower static ring, the upper cover and the upper valve cap; the upper static ring is connected with the end surface of the upper dynamic ring in a sealing manner; and the lower static ring is connected with the end surface of the lower dynamic ring in a sealing manner.
Description
Technical field:
The utility model is relevant with the valve of the fine powder medium transport of thermal power plant, polysilicon and Coal Chemical Industry industry, and is especially relevant with the two plate valves of the mass transport of band edge face seal.
Background technique:
Existing mass transport valve, packing seal is used in rotating shaft more, leaks outside to stop the pressure medium in the valve pocket.Packing seal can not compensate automatically, when between rotating shaft and filler because of constantly rotating wearing and tearing when the gap occurring, will produce medium and leak outside.In fine powder is carried, leak outside because of what packing seal produced, seriously polluted environment, influenced production and operator's health.
The model utility content:
The purpose of the two plate valves of the utility model mass transport provides the two plate valves of mass transport of a kind of rational in infrastructure, good seal performance, a kind of band edge face seal of compensate for wear automatically.
The utility model is achieved in that
The two plate valves of the utility model mass transport, bonnet 1 is connected with valve body with bottom flange 11, and bonnet 1 is connected with supporting plate 2; Bracket 3 on the supporting plate is hinged with an end of cylinder 4, and the piston rod that the other end of cylinder 4 exposes is hinged through the end of coupling yoke 5 with connecting rod 6, and the upper end of the other end of connecting rod 6 and rotating shaft 7 is connected; The lower end of rotating shaft 7 is supported on the inner face of bottom flange 11, and rotating shaft 7 is connected with an end of pivoted arm 8, and the other end of pivoted arm 8 has the vertical support cover; The upper and lower end of supporting sleeve respectively with the axle core of upper and lower valve plate 9,10 movingly, upper and lower valve plate respectively with upper and lower valve gap on valve base sealing cooperate, have following stationary ring 18 to be connected between bonnet 1 and the rotating shaft 7 with bonnet; Loam cake 17 is connected with bonnet 1; There is last stationary ring 19 to be connected between loam cake 17 and the rotating shaft 7, is with upper and lower rotating ring 15,14 in the rotating shaft 7, the O RunddichtringO is arranged between upper and lower rotating ring and the rotating shaft with loam cake 17; Pressure spring 16 is arranged between the upper and lower rotating ring; The O RunddichtringO is arranged between upper and lower stationary ring and loam cake, the bonnet, and last stationary ring is connected with last rotating ring end face seal, and following stationary ring is connected with following rotating ring end face seal.
The utility model has following advantage:
(1) end face seal is used in the valve rod rotating shaft, after rotating ring and the wearing and tearing of stationary ring sealing pair, can be compensated automatically by spring, has prevented that effectively the valve pocket medium from leaking outside, and sealing is reliable, long service life.
(2) applied widely.
Description of drawings:
Fig. 1 is the structural drawing of the utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the local I enlarged view at Fig. 1 rotating shaft end face seal position.
Embodiment:
The supporting plate 2 of the two plate valves of the utility model mass transport is connected with bonnet 1; An end that is positioned at bracket 3 and cylinder 4 on the supporting plate 2 is hinged; The other end of cylinder 4 is hinged through the end of coupling yoke 5 with connecting rod 6 with the cylinder piston rod that exposes; One end of the other end of connecting rod 6 and rotating shaft 7 is connected, and valve plate 9 is connected with the pivoted arm 8 that lower valve plate 10 rotates the other end of rotating shaft 7 with driving upward.Rotating shaft 7 is bearing on bottom flange 11 inner faces.
Rotating shaft 7 drives rotating ring 14 and 15 rotations, and with stationary ring 18 and 19 formation end face seals on the axle sleeve that is fixed on bonnet 1 and loam cake 17 compositions, rotating ring and stationary ring wearing and tearing back are compensated by spring 16 automatically.Rotating ring and rotating shaft, stationary ring and shaft room are with the seal with elastometic washer of O type.
There is the band screw bonnet 1 of the utility model and bottom flange 11 exterior edge faces and at the adpting flange 13,12 of same shaft axis, and valve can adopt double-screw bolt to wear nut with pipeline to be connected.
The structure of the utility model, inside nominal diameter DN is eight kinds of 50～300mm, and nominal pressure PN is seven kinds of 0.3～6.4 MPa, and totally 56 descriptions can satisfy the needs of thermoelectricity, polysilicon and the different operating modes of Coal Chemical Industry industry.
