Abstract
The invention relates to the technical field of a valve device and especially relates to a rotary ceramic feed valve. the rotary ceramic feed valve comprises an upper valve body and a lower valve body which are fixedly sealed and connected, a valve rod is arranged in the lower valve body, the valve rod adjacent to one side of the upper valve body is provided with a valve plate in which a spring connected with the valve plate is embedded; the connection position of the upper valve body and the valve plate is provided with a sealing ring; the outer wall of the upper valve body is provided with a spindle which is connected with the valve rod, the upper half part of the spindle is connected with a swinging arm which is connected with a pneumatic device. The rotary ceramic feed valve is rationally designed, prolonged in service life, and resists wear and heat, thus the feed valve is applied to a thermal power plant, and various dust and granule conveying systems in metallurgy, medicine and chemical engineering, it is low in dust deposition and simply maintained, and has excellent sealing performance and long service life, without jamming.
Description
Technical field
The present invention relates to valve arrangement technical field, especially a kind of for the rotary-type ceramic feeding valve in all kinds of dust, the particle transport systems such as thermal power plant, metallurgy, medicine, chemical industry.
Background technique
The feeding valve adopted in the transporting system of all kinds of dust such as thermal power plant, metallurgy, medicine, chemical industry, particle adopts carbon steel material usually, due to uninterruptedly washing away of powder particles, seal ring and valve plate are easy to just be worn through, sealability and wear-resisting property poor, whole feeding valve is finally caused to be scrapped, feeding valve is short for working life, not only increases cost, also can affect transfer efficiency.According to stainless steel, manufacture cost can be increased widely.Conventional feeds valve arrangement is complicated, and often has card ash and tie grey phenomenon, affects working life greatly.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of structure simple, the wear-resisting and feeding valve of good seal performance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of rotary-type ceramic feeding valve, there is the upper valve body of fixed seal connection and lower valve body, be provided with valve rod in described lower valve body, valve rod is provided with valve plate near upper valve body side, and valve rod is embedded with the spring connected with valve plate; Described upper valve body and valve plate connecting part are provided with seal ring, and valve plate is embedded with packing ring, and lower valve body is provided with material feeding mouth; Described upper valve body outer wall is provided with the rotating shaft be connected with valve rod, is arranged with shaft seat and end cap outside rotating shaft, and the rotating shaft first half is connected with swing arm, and swing arm is connected with Pneumatic actuator.
Further, described lower valve body is shaping is provided with flange, and flange is provided with mounting hole.
Further, bearing is provided with between the outer wall of described rotating shaft and the inwall of shaft seat.
Further, described seal ring is positioned at valve plate near the side of upper valve body on the surface.
Further, described seal ring is ceramic seal circle.
Working principle: pneumatic actuator makes valve plate rotate by rotating shaft and swing arm, spiral compression spring is loaded between valve plate and seal ring, 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, thus contribute to compensating expanding with heat and contract with cold of valve components, and the impact of any economy on feeding valve sealability can be overcome, can also prevent particle media from entering between sealing surface.The official post of sealing surface of valve plate and seal ring face frictional force in tangential direction obtains valve plate and can produce rotation in opening-closing process, this characteristic makes produce grinding, polishing action between sealing surface, when opening charging, eddy current can be produced, the material vortex formed can clean valve cavity voluntarily, reduce dust stratification, without bite.
The invention has the beneficial effects as follows: the present invention is reasonable in design, there is performance that is wear-resisting, heat resistanceheat resistant, extend the working life of valve, be applicable to the transporting system of all kinds of dust such as thermal power plant, metallurgy, medicine, chemical industry, particle, dust stratification is few, without bite, safeguards simple, favorable sealing property, long service life.
