Abstract
The invention discloses a kind of stop valve clack grinding agent, the stop valve clack grinding agent is made up of the raw material of following weight portion：60 70 parts of silicon-carbide particle, 20 30 parts of diadust, 40 50 parts of glycerine, 10 20 parts of polypropylene glycol, 30 40 parts of paraffin, 8 12 parts of oxirane, 58 parts of sodium tripolyphosphate, 25 parts of dibutyl hydroxy toluene.Mainly subpackage silicon carbide-containing particle and diadust are ground to form in stop valve clack grinding agent of the invention, wherein silicon-carbide particle is divided into two kinds of sizes, when being so ground operation with the grinding agent, the carborundum of bulky grain to the removing speed of dirt faster, when grinding so as to effectively shorten flap, flap grinding efficiency is improve.
Description
Technical field
The present invention relates to valve manufacture field, more precisely, being a kind of stop valve clack grinding agent.
Background technology
Stop valve belongs to forced seal formula valve also known as pipe valve valve, so in valve closing, it is necessary to apply to press to flap
Power, is not leaked with forced seal face.When medium enters valve by flap lower section, the resistance overcome required for operating physical force is valve
The frictional force of bar and filler and the thrust as produced by the pressure of medium, the power of closing valve are bigger than the power of valve opening door, so valve rod
Diameter it is big, the failure of valve rod bending can otherwise occur.It is divided into three kinds by connected mode：Flange connection, screwed connection, welding
Connection.After occurring from the valve of self sealss, the medium flow direction of stop valve just changes by entering valve pocket above flap, at this moment in medium pressure
Under power effect, the power of closing valve is small, and the power of valve opening door is big, and the diameter of valve rod can be reduced correspondingly.Meanwhile, in medium effect
Under, the valve of this form is also tighter.China's valve " three change to " once specified, the flow direction of stop valve, without exception using from upper
Under.When stop valve is opened, the Lift of flap, flows have reached maximum when being the 25%~30% of nominal diameter, represent valve
Door has reached fully open position.So the fully open position of stop valve, should be determined by the stroke of flap.
Surface is easily corroded or deposits dirty stop valve clack in use, it is therefore desirable to grinding agent to it
Surface is ground treatment, to extend the service life of flap.But, the grinding efficiency of the grinding agent for using at present is general not
Height, milling time is more long, increases the operation cost of flap grinding.
The content of the invention
The present invention mainly solves the technical problem existing for prior art, so that providing, a kind of grinding efficiency is higher to cut
Only valve flap grinding agent.
Above-mentioned technical problem of the invention is mainly what is be addressed by following technical proposals：
A kind of stop valve clack grinding agent, is made up of the raw material of following weight portion：
Silicon-carbide particle 60-70 parts, diadust 20-30 parts, glycerine 40-50 parts, polypropylene glycol 10-20 parts, paraffin
30-40 parts, oxirane 8-12 parts, sodium tripolyphosphate 5-8 parts, dibutyl hydroxy toluene 2-5 parts.
Wherein, silicon-carbide particle is spherical, and comprising size two kinds of particles, bulky grain granularity is 220-250um, and sphericity is
0.65-0.7, little particle granularity is 120-150um, and sphericity is 0.75-0.8, and bulky grain is 5 with short grained weight ratio：3；
The preparation method of the stop valve clack grinding agent is：
Reactor, temperature in the kettle is added to be increased to 80-85 silicon-carbide particle, diadust, glycerine, polypropylene glycol
DEG C, it is sufficiently stirred for 20-30 minutes, continuously add paraffin, oxirane, sodium tripolyphosphate, dibutyl hydroxy toluene, temperature reduction
To 60-65 DEG C, it is sufficiently stirred for 10-15 minutes, is obtained final product after natural cooling.
