Description
Technical field
The utility model relates to valve arrangement technical field, especially a kind of rotary-type ceramic inlet valve for all kinds of dust such as thermal powerplant, metallurgy, medicine, chemical industry, particle transport system.
Background technology
The inlet valve adopting in the delivery system of all kinds of dust such as thermal powerplant, metallurgy, medicine, chemical industry, particle adopts carbon steel material conventionally, due to uninterruptedly washing away of powder particle, seal ring and valve plate are easy to just be worn through, sealing property and wear resisting property are poor, finally cause whole inlet valve to be scrapped, inlet valve is short service life, has not only improved cost, also can affect transport efficiency.If employing stainless steel, can increase manufacturing cost widely.Conventional feeds valve arrangement is complicated, and often has card ash and tie grey phenomenon, affects greatly service life.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of simple in structure, the inlet valve of wear-resisting and good seal performance.
The utility model solves the technical scheme that its technical matters adopts: a kind of rotary-type ceramic inlet valve, upper valve body and the lower valve body with fixed seal connection, in described lower valve body, be provided with valve rod, valve rod is provided with valve plate near upper valve body one side, and valve rod is embedded with the spring joining with valve plate; Described upper valve body and valve plate joint are provided with seal ring, and valve plate is embedded with packing ring, and lower valve body is provided with inlet point; Described upper valve body outer wall is provided with the rotating shaft being connected with valve rod, and rotating shaft is arranged with shaft seat and end cap outward, and the rotating shaft first half is connected with swing arm, and swing arm is connected with pneumatics.
Further, the one-body molded flange that is provided with of described lower valve body, flange is provided with mounting hole.
Further, between the outer wall of described rotating shaft and the inwall of shaft seat, be provided with bearing.
Further, described seal ring is positioned on the side surface of valve plate near upper valve body.
Further, described seal ring is ceramic seal circle.
Principle of work: pneumatic actuator rotates valve plate by rotating shaft and swing arm, between valve plate and seal ring, load spiral compression spring, spring force makes sealing surface of valve plate and seal ring face fit tightly all the time, and allow again valve plate to move in the vertical direction, thereby contribute to compensate expanding with heat and contract with cold of valve components, and can overcome the impact of any economy on inlet valve sealing property, can also prevent that particle media from entering between sealing surface.The official post of sealing surface of valve plate and the friction force of seal ring face in tangential direction obtains valve plate can produce rotation in opening-closing process, this characteristic makes can produce grinding, polishing action between sealing surface, when opening charging, can produce eddy current, the material vortex forming can clean valve cavity voluntarily, reduce dust stratification, without bite.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, there is performance wear-resisting, heat resistanceheat resistant, extended the service life of valve, be applicable to the delivery system of all kinds of dust such as thermal powerplant, metallurgy, medicine, chemical industry, particle, dust stratification is few, without bite, safeguard simply favorable sealing property, long service life.
