Background technique
For the manufacturing of heavy caliber axial flow type check valve, be a difficult problem at present.Because the weight and volume of heavy caliber safety check is large, difficulty of processing is very large.Generally, the weight of valve body has several tons of weights, and the weight of flap has one ton of left and right, and only valve seat also has several thousand kilograms, and the huge monster of super weight like this not only brings very large difficulty large to processing, and the support of flap and a sealing hang-up especially.
For current conventional axial flow type check valve, be also only applicable to the pipeline of 20 cun of following latus rectums.Between sealing surface of seat and valve clack sealing surface, adopt conical surface seal, the afterbody of flap has guide rod, and guide rod external diameter is provided with spring, and when medium back flow, reaction force makes the flap conical surface contact with the valve seat conical surface, to stop medium back flow.The safety check of this kind of seal form, cannot be applied to large bore valves.The one, because, large bore valves, because size is large, Heavy Weight, sealing cone is difficult to processing; The 2nd, because large bore valves is generally applied to the pipeline that pressure medium is large, the super large weight of valve self in addition, the support difficulty of spool is quite large, only depends on the flow resistance of rod-support at rear portion to realize.
Summary of the invention
Technical barrier to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of heavy caliber axial flow type check valve is provided, and by front and back dual support, makes flap stress balance, and moving equilibrium is reliable, and good seal performance.
Technical solution of the present invention is, comprises valve body 1, valve seat 2 and flap 5, and valve seat 2 is embedded on valve body 1, and flap 5 is placed in valve pocket, it is characterized in that: in valve body 5, be also provided with air guide sleeve 12, it is conical that air guide sleeve 12 bodies are, and coaxially arranges with valve body 1; The central authorities of air guide sleeve 12 are provided with supporting tube 8, and the bottom of air guide sleeve 12 is provided with air guide sleeve base 11, and supporting tube 8 is connected as a whole by stiffening rib 13,10 with air guide sleeve 12 bodies respectively with air guide sleeve base 11; The inner side of valve seat 2 is provided with supporting frame 3; Flap 5 is "T"-shaped, and its T shape bar is provided with spring 7, and inserts in the supporting tube 8 of air guide sleeve 12 central authorities, is slidably matched, and supports wherein with it; On the T shape end face of flap 5, be connected with supporting slider 4, its supporting slider 4 is supported on supporting frame 3, and is slidably matched with it.
Supporting frame 3 consists of inside and outside two circles, and its outer ring is welded on valve seat 2 and valve body 1, and inner ring is provided with central through bore that can supported slide bar 4.
On the T shape end face of flap 5, by screw thread, be connected with supporting slider 4.
On the sealing surface of flap 5T shape end face, on the sealing surface of valve seat 2 end faces, heap is welded with hard alloy layer respectively.
On valve seat 2, be also provided with the O-ring seals 6 of anti-explosion type.
Air guide sleeve 12 is fixed on valve body 1 by hexagon socket head cap screw 9 by air guide sleeve base 11.
The profile of valve body 1 is horizontal " bottle " shape.
The present invention and prior art compare, the advantage possessing, and soft or hard double seal, sealing is reliable; The forward and backward balanced type dual support of T-valve lobe, makes flap can overcome the gravity of self, and unrestricted motion is vertically steadily without jam; Valve body is designed to " bottle " shape, and pressure medium is effectively discharged in valve body, has ensured that the long-term safety of large bore valves is used, the working life of having improved valve; Air guide sleeve both can carry out water conservancy diversion to medium, can support flap again, made the present invention realize heavy caliber check function.
