Description
Technical field
The invention belongs to valve field, be specifically related to a kind of double inclined plane eccentric-butterfly-valve.
Background technique
Traditional three eccentric butterfly valve adopts Multi-layer sealing structure (metallic graphite carbon, the combination of tetrafluoroethylene or asbestos), although sealing configuration has good elasticity, is easy to ensure the qualified of product zero leakage.But this structure also existing defects: 1) conventional construction sealing principle is still and produces larger specific pressure by the distortion of sealing seat elastic packing, sealing is still and seals by graphite or asbestos, metal just plays skeletal support effect, the hardness of graphite and asbestos is very low, so there is being the operating mode of particle, the sealing of conventional multilayer time is being easy to destroy.2) during switch, valve sealing face deformation comparison is large, so the fretting wear of turn-off transient sealing surface is relatively more serious, has influence on its life-span.3) under low temperature, Multi-layer sealing seat is due to the effect of expanding with heat and contract with cold of material, and tetrafluoroethylene, graphite, asbestos seal seat thickness can be thinning, so that sealing seat and cover plate produce gap, causes leakage.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide one and can realize 90 degree of rotations without friction under the various flow direction, pressure and temperature, zero leakage, the double inclined plane eccentric-butterfly-valve that the life-span is long.
The present invention is achieved through the following technical solutions:
A kind of double inclined plane eccentric-butterfly-valve, it is characterized in that, comprise valve body, valve rod, valve plate and metal sealing seat, be provided with import, outlet in valve body and be communicated with the valve pocket of import and outlet, the valve pocket part of valve body offers axis hole, and valve rod is fixedly connected with valve plate through described axis hole;
Described valve body is provided with the metal seat valve with valve body, described valve plate opens and closes under the drive of valve rod on metal seat valve; Metal sealing seat is arranged on valve plate by the clamping of seal ring cover plate, and is sealed and matched with metal seat valve;
Form two the first gaps and the second gap interconnected between described metal sealing seat and valve plate, be provided with metal C type circle in described first gap, described metal C type circle is partially embedded in the groove on valve plate surface; Selfsealings composite structure is provided with in described second gap.
The further setting of the present invention is, described selfsealings composite structure comprises the first seal ring, gasket ring and the second seal ring, described first seal ring is provided with V-type groove, described gasket ring is arranged in described V-type groove, one end face of described second seal ring is provided with spur, and described spur abuts with the V-type channel opening end of the first seal ring.
The further setting of the present invention is, described valve plate and valve rod are fixed together by multiple taper pin.
The further setting of the present invention is, is provided with muff, Packing seat, filler and Gland between described valve rod and valve body, and filler is arranged on Packing seat and Gland.
Double inclined plane eccentric-butterfly-valve of the present invention takes integrated type metal sealing seat and the structure of close formula of floating, and valve body built-up welding stellite forms integrated type metal seat valve, has higher mechanical property, rub resistance weares and teares, intensity is high, and hardness is high, is applicable to various operating mode; Metal C type circle simultaneously under metal sealing seat, less with metal sealing seat area of contact, metal sealing seat is easy to mobile, oneself centering position.So at switching moments, metal sealing seat is easy to mobile, thus avoids the fretting wear with valve body; The present invention significantly can promote working life and the usability of butterfly valve.
