Abstract
The invention belongs to the technical field of machinery manufacturing and particularly relates to a wear-resisting seal valve. The wear-resisting seal valve comprises a valve body, a cylinder, a guide rail, a connecting rod, a pin shaft, a pressing rod, a valve plate, a guide wheel and a sealing structure, wherein the cylinder is provided with the guide rail; the valve plate is connected with the connecting rod and the pressing rod by virtue of the pin shaft; the guide wheel is arranged on the pressing rod and in the guide rail; the sealing structure is formed on the valve body and comprises sealing rings and grooves; the grooves have symmetrical cavity structures and are matched with the sealing rings; the thickness of each sealing ring is more than the depth of each groove; sealing gaskets are arranged on the valve plate; and a wear-resisting coating is coated on the surface of the valve plate. As the wear-resisting coating is coated on the surface of the valve plate of the seal valve, the wear-resisting and corrosion-resisting properties of the seal valve are improved. As the sealing structure is formed on the valve body of the seal valve, the sealing effect of each sealing ring in the seal valve is improved, and a loosening effect is added.
Description
Technical field
The invention belongs to machinery manufacturing technology field, particularly relate to the wear-resistant seal valve.
Background technique
At present, seal valve plays an important role at industrial particularly aviation industry and chemical industry.Seal valve of the prior art, ring structure single, be difficult to the sealing effect that reaches good, and the valve plate of seal valve easily is subject to the erosion of harmful atmosphere or corrosive materials, shortened the working life of valve.
Summary of the invention
Technical problem to be solved is to overcome the defect that prior art exists, and provides a kind of wear resistant corrosion resistant and sealing good wear-resistant seal valve.
The technology used in the present invention solution is the wear-resistant seal valve, comprises valve body, cylinder, guide rail, connecting rod, bearing pin, depression bar, valve plate, upper saw pulley and sealing configuration, and described cylinder is provided with guide rail; Described valve plate is connected with depression bar with connecting rod by bearing pin; Described depression bar is provided with upper saw pulley, and upper saw pulley is arranged in guide rail; Be provided with sealing configuration on described valve body.
Described sealing configuration comprises seal ring and groove, and described groove is symmetrical cavity body structure, and seal ring matches with groove, and the thickness of seal ring is greater than the degree of depth of groove.
Be provided with sealing gasket on described valve plate.
Described valve plate surface is coated with wear resistant coating.
Compared with prior art, the beneficial effect that the present invention has is: 1. the present invention, by seal valve valve plate surface coating wear resistant coating, has improved the wear-resisting and decay resistance of seal valve;
2. the present invention, by the seal valve valve body, sealing configuration being set, having improved the sealing effect of seal ring in seal valve and has also increased relaxation effect.
