Two. background technique
Mixing extrusion pelleting machine set is one of most important equipment of petrochemical industry ethylene project.Melt compounded degree modulating valve and driving valve all belong to the extruding pelletization system of extruder grain unit.The main effect of melt compounded degree modulating valve is by changing the corner of dish shape valve body, regulate the mixing degree of melt in cylindrical shell, promptly having regulated the back pressure of material in the extrusion system, thereby changed the plasticizing rate of material and the actual consumption of main drive motor; And the effect of driving valve be when driving a large amount of not have the good raw material of plasticizing and the material that is mixed with impurity from then on valve arrange earthward, otherwise those materials can be with the moulding hole plug of template; When treating ordinary production, again materials flow is transformed into the heading in downstream.In the unit in the past, mixing degree modulating valve is two valve bodies that independently separate with the employing of driving valve, thereby causes the passage lengthening of fused materials, has increased the cost of device fabrication, unfavorable technology controlling and process, and energy consumption strengthens.
Three. summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of mixing milling squeezing granulation units melt control valve is provided, the valve body of melt compounded degree modulating valve and driving valve unites two into one, and is simple in structure, easy and simple to handle, energy-conservation.
The technological scheme that the present invention is adopted for achieving the above object is: mixing milling squeezing granulation units melt control valve; have melt modulating valve runner and driving valve traveller passage in the valve body; the modulating valve runner intersects with driving valve traveller passage; the melt modulating valve be equipped with rotating in the material runner and circulation area with corner different and different spool or valve plates; have the curved passage of melt straight passage and refuse material on the driving valve traveller, the curved passage of melt straight passage and refuse material can be communicated with the modulating valve runner respectively.
The curved passage of described refuse material is the curved passages of 90 degree.
Described melt modulating valve is in the material runner rotatingshaft to be installed, and spool or valve plate fixedly are housed on the rotatingshaft, and as fixedly connected by pin or key, rotatingshaft connects control gear.
Described valve body and spool or valve plate are that the surface is through alloyed steel valve body and spool or valve plate wear-resisting, anti-corrosion processing.
Described rotatingshaft does not directly contact with valve body, between rotatingshaft and the valve body axle bush is housed.
Sealing cover is equipped with in described rotatingshaft both sides, and wherein a side sealing lid and valve body adopt Spielpassung, the fused materials sealing; Rotatingshaft setting sleeve and sealing gasket are housed between opposite side sealing cover and the rotatingshaft, and sealing gasket and setting sleeve and valve body be Spielpassung respectively, the fused materials sealing.
Described melt modulating valve drive unit be electronic, surge or manual overvide.
The end of the rotatingshaft of described melt modulating valve is provided with an angular displacement sensor, detects the angle of valve plate or spool and material runner at any time.
Offer heating or cooling channel on the described valve body.
The present invention scientifically designs the modulating valve runner and the curved passage of refuse material of fused materials, on shared valve body, be processed with melt modulating valve passage and driving valve traveller passage respectively, modulating valve and driving valve are united two into one, needs according to the material processing technology process heating or cooling channel and temperature detection hole etc. simultaneously, assemble according to parts concrete structure separately then, the adjustment of melt compounded degree modulating valve is to realize by rotational valve plate; It is to realize by moving up and down of driving valve traveller that the function of driving valve realizes.Compare with modulating valve, the driving valve of traditional equivalent effect, have compact structure, floor space is few, and the manufacturing cost is low, and is convenient for installation and maintenance, and technology controlling and process is easy, advantages such as energy efficient.

Fig. 1 is structural representation of the present invention when production (improper).
Fig. 2 is structural representation of the present invention (during an ordinary production).
Fig. 3 is a melt compounded degree modulating valve structure diagram.
Five, embodiment
Be the mixing milling squeezing granulation units melt control valve of abnormal operating state as shown in Figure 1.Under the effect of the oil cylinder (not drawing among the figure) of driving valve traveller 3 upper ends, traveller moves up, and the curved passage 4 of 90 degree refuse material of melt modulating valve runner 5 and driving valve traveller is communicated.Accompanying drawing 2 is depicted as when treating proper functioning, and traveller moves down, and melt modulating valve runner 5 is communicated with the straight passage 6 of driving valve traveller, makes material enter channel 8 through the straight passage of modulating valve runner and driving valve.In the modulating valve runner 5 rotatingshaft 9 is installed as shown in Figure 3, the surface fixedly is housed through alloyed steel spool 1 or valve plate wear-resisting, anti-corrosion processing by key on the rotatingshaft, that rotatingshaft connects is electronic, surge or manual overvide.Rotatingshaft does not directly contact with valve body 2, connects by two end supports axle bush 11, and sealing cover 10 is equipped with in rotatingshaft axle bush both sides, and wherein a side sealing lid and valve body adopt Spielpassung, the fused materials sealing; Rotatingshaft setting sleeve 12 and sealing gasket 13 are housed between opposite side sealing cover and the rotatingshaft, sealing gasket and setting sleeve and valve body adopt Spielpassung respectively, the fused materials sealing, and sealing cover is equipped with stuffing box gland 14 outward, stuffing box packing 15 is housed, with the sealing gasket double seal in the stuffing box gland.
Also an angular displacement sensor can be set in the end of rotatingshaft, detect the angle of valve plate or spool and material runner at any time, the sensor signal input control device is convenient to the mixing degree of more accurate adjusting.Regulate the melt compounded degree under the effect of modulating valve valve plate, the melt of regulating behind the mixing degree enters the extruder grain machine barrel.Can offer heating or cooling channel 7 according to material processing technology needs on the valve body, guarantee the material technological temperature.
Drive the starting stage as shown in Figure 1; driving valve traveller slides into the curved passage of refuse material and is communicated with the modulating valve runner in passage; this moment, straight passage was not communicated with; thereby will not have good raw material of plasticizing and the material that is mixed with impurity to arrange earthward in a large number, thereby protected the safe in utilization of upstream device from curved passage.
