Abstract

The utility model relates to a ceramic double-gate fly ash valve. The ceramic double-gate fly ash valve comprises a valve body, a valve base, a gate, a valve rod and a transmission mechanism. The ceramic double-gate fly ash valve is characterized in that the gate adopts a floating type automatic sealing structure, the gate is arranged on cylinders on two sides of a gate frame in a sleeved mode through circular holes formed in the back face of the gate to form the floating type automatic sealing structure, and the floating type automatic sealing structure can rotate along with the gate frame in the circumferential direction of the cylinders; a through hole which is concentric with a valve body channel is formed in the gate frame, a spring is arranged in the through hole, and two ends of the spring press the back face of the gate in an abutting mode; a ceramic sealing ring is embedded in the valve body to form the valve base, and a ceramic sealing ring is embedded in a gate base plate to form a gate sealing face. The gate can rotate in an opening or closing process, and even abrasion of the circumference of the sealing face is achieved. The valve base and the gate sealing face are made of ceramic materials, and the advantages of being resistant in abrasion, resistant in corrosion, resistant in washing, reliable in sealing performance, long in service life and the like are achieved. The ceramic double-gate fly ash valve is suitable for valves of conveying pipes for media of dry ash, cerement, powder and the like.

Description

Pottery double-flashboard flying dust valve
Technical field
The utility model belongs to valve field, particularly about a kind of gate valve.The utility model is applicable to the valve of dry ash, cement, the contour wear medium conveyance conduit of powder.
Background technique
In dry ash pneumatic conveying process pipelines such as mine, colliery, cement plant, power plant, medium is carried through the situation of be everlasting pressurization or negative pressure.Carry the pipeline of dry ash such as power plant's strength, be in pipeline, to feed pressure or vacuumize to carry, dry ash is high-speed motion under gas pressure, just as the emery wheel that rotates at a high speed, pipe-line equipment is produced wearing and tearing fast, general Structural Hardware valve is worn very soon and loses break-in facility, and working life is very short.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, provides that a kind of wear-resisting property is good, the ceramic double-flashboard flying dust valve of long service life.
The technical solution of the utility model comprises valve body, valve seat, flashboard, valve rod, driving mechanism, Sealing and assembling set, is provided with stuffing seal between valve rod and the valve body, and flashboard adopts the double-flashboard structure, is connected the valve rod lower end by the flashboard frame; It is floating type from movable sealing structure mainly to be that flashboard adopts, and the described floating type circle hole sleeve that is flashboard by the back side from movable sealing structure is contained on the cylinder of flashboard frame both sides, can rotate with flashboard frame cylinder circumferencial direction; The flashboard frame is shaped on the through hole concentric with valve channel, mounting spring in this through hole, and the both ends of the spring roof pressure is at the flashboard back side; Valve seat is embedded on the valve body by the ceramic seal circle to be formed, and the flashboard sealing surface is embedded on the flashboard substrate by ceramic-seal ring to be formed.
In above technological scheme, valve body is made up of main valve body and side valve body, and main valve body both sides and side valve body are tightly connected by bolt.
In above technological scheme, stuffing seal adopts spring attachment, this spring attachment is made up of filler gland and gland spring, and filler gland lower end is fitted on the filler, and the gland spring is installed between the spring capping of filler gland upper end and driving mechanism lower end.
The utility model has the advantages that: flashboard adopts floating type from movable sealing structure, and flashboard can be rotated in opening-closing process, realizes the uniform wear of sealing surface circumference; Valve seat and flashboard sealing surface adopt stupalith, have wear-resisting, corrosion resistant, anti-characteristics such as wash away.Its sealability is reliable, long product lifecycle.
