Description
Technical field
This utility model belongs to universal machine valve technology field, is that stone coal dust is a kind of specially more particularly to using medium
Use valve.
Background technology
Valve is control parts in pipeline fluid induction system, for changing path section and media flow direction, has
The functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release, application is widely.Traditional valve highly versatile, but
Finished products species is a lot, and its production technology is Protean, being very restricted on being suitable for of universal valve.This practicality
New be mainly used for a kind of special valve that medium is stone, coal dust, it be directed to medium particularity valve is weighed
New optimization design, all has breakthrough from material to structure.
Utility model content
The purpose of this utility model is to improve the deficiency of prior art, provides a kind of medium to be stone coal dust special service valve,
Metal flashboard is disc design, and the material with valve seat is all diamondite, and actuator promotes flashboard to move up and down realization
The switch motion of valve.The sealing surface of flashboard is fitted tightly with valve seat by spring, and spring pressure makes flashboard fit tightly all the time
On valve seat, allow valve disc to have displacement in the vertical direction of sealing surface, it is cold due to expanding that this helps compensate for valve partses again
The micro abrasion producing after the deformation contracted and cause and multiple switching, overcomes the impact to sealing for any economy and can prevent
Granule medium enters between sealing surface, and in the opening-closing process of valve, valve base sealing is in the face of flashboard rubbing in tangential direction
The difference of wiping power, makes flashboard produce rotation can constantly shearing while rectilinear movement and is possible in technical process with cleaning
It is deposited in the medium in valve pocket, improve the service life of valve on the whole.
For realizing this utility model purpose, there is provided technical scheme below: a kind of stone coal dust special service valve, its feature exists
In include metal valve body, connect with the left and right flange at metal valve body two ends, be opened in left flange upper valve bore, be installed on valve seat orifice
Valve seat, metal valve body tip side wall is provided centrally with valve rod hole, and valve rod in the hole is provided with valve rod, and valve stem tip connects pneumatic holding
Row mechanism, valve rod bottom connecting spring seat, spring base includes horizontal, is arranged at the vertical spiral shell at horizontal tube body sidewall center
Bar, screw rod is spun with valve rod bottom screw, setting spring in horizontal, is sheathed on the left and right supporting post-rod of both ends of the spring, water
Flat body is inserted in the countersunk head in the hole that plate-like flashboard center opens up, and left support push rod is pressed in counter sink bottom surface, plate-like flashboard in
Valve seat cooperates, and horizontal right-hand member is inserted in adapter sleeve.
Preferably, valve rod hole top connects sealing shroud, sealing shroud is connected with pneumatic actuator bottom end seal, valve rod and
Be provided between sealing shroud automatic compensate packing box assembly, automatically compensate packing box assembly include pad, spring, filler pad with
And stuffing-box.The mild wear of valve rod and filler at work can be compensated.
Preferably, valve seat and plate-like flashboard are made up of diamondite material.
Preferably, hand inspection mouth is offered on right flange, hand inspection mouth is provided with cover plate.Can online at any time
Observe working condition in valve pocket for the medium.
Preferably, offering purge hole in metal valve body, purging in the hole is provided with plug.Do not need valve from pipeline
On disassemble and can use compressed air purging valve pocket, realize on-line maintenance.
Preferably, right flange valve opening minimum point is flushed with metal valve body valve pocket minimum point, constitute and lead cinder notch.Valve pocket is not deposited
Slag.
This utility model beneficial effect: general structure design is short and sweet, it is that Design and Machining has on side flange first
Hand inspection mouth, can observe working condition in valve pocket for the medium online at any time；Secondly on valve body, Design and Machining has purging
Compressed air purging valve pocket can be used it is not necessary to disassemble valve from pipeline in hole, easily realizes on-line maintenance.Three hold
The piston rod of row mechanism and valve rod are all sealed in valve internal, do not expose, are not affected by bad working environments.Four is that stuffing-box sets
Count automatic compensation packing seal, the mild wear of valve rod and filler at work can have been compensated.Five are, in the port of export of valve
Devise and lead cinder notch, inside valve pocket, do not deposit slag.
Therefore, this utility model disclosure satisfy that using scene technical requirements, can easily realize On line inspection and
Line is safeguarded, is particularly well-suited in stone coal dust equigranular mixture condition, the high life of valve, ensure that production and operation are looked forward to
The safe and stable operation of industry, obtains good economic benefit.
