Description
Technical field
The utility model relates to paraffin continuous shaping machine casting device, is specifically related to the novel casting valve of a kind of paraffin continuous shaping machine.
Background technique
What existing paraffin continuous shaping machine used is threeway rotation switching valve, and its structure is basically: valve body is the cuboid that adopts the alloyed steel forging, and finished size is 410mm * 195mm * 96mm, is fixedly mounted on the bottom surface of hopper; Vertically connect that install can be through the valve rod of pneumatic direct control and electronic indirect control direction conversion in the valve body, equidistantly above the valve body process slotted eye two and half logical, an all-pass in order, be respectively material inlet; When liquid wax cylinder piston was raised, valve rod was by interlock effect rotation, and when the liquid wax in liquid wax cylinder reached and limits the quantity of, the valve rod rotation was closed outlet immediately with inlet for 45 ° and opened, and makes the liquid wax in the liquid wax cylinder flow to fluid director (nozzle); Refluxing opening is to open refluxing opening when liquid wax in the hopper reaches automatically after the modulating valve on the material pipeline when limiting the position is received the signal of level meter, and unnecessary liquid wax is got back to liquid wax basin through reflux pipeline.Six casting valves are installed below the hopper side by side.Its deficiency is: 1. complex process, and operation is many, and the manufacturing cycle is long; 2. volume is big, and the material consumption is big, and it is big to take up room; 3. weight is big, and is mounted in the hopper bottom surface, the maintenance, more change poles is not convenient; Need two kinds of power to control outer power system complex respectively when 4. working; 5. because of belonging to the mechanical chain transmission, the casting time is restricted at regular time and quantity, and 5 kilograms of liquid waxes of every notes need 10 seconds, and efficient is low; 6. because of its outlet flow is to lead directly to not have buffer space, very fast with its flow velocity under the equal pressure, the moment that is expelled to cake wax can form reflection, vaporific splashing occur, and has both influenced the casting precision, causes the waste of raw material again, also befouling environment.
Summary of the invention
The purpose of the utility model is to provide a kind of paraffin continuous shaping machine novel casting valve, i.e. integrated, the simplification of structure is convenient to automatic control, and then is addressed the above problem.
The utility model adopts following technological scheme: the casting valve is combined by cylinder (1), valve rod (2), valve body (3), spool (5) and valve seat (7); Cylinder (1) is connected with valve rod (2) upper end, bottom in valve body (3), valve rod (2) lower end, and the end studs with spool (5), and valve body (3) lower end is processed to form valve seat (7).
Said valve body (3) is the cylindrical three way valve of φ 100mm * 100mm, and its threeway is respectively inlet (12), outlet (8) and refluxing opening (4), is clear opening; Inlet (12) and refluxing opening (4) are distributed in corresponding side, cylinder shape valve (3) middle and upper part; Inlet (12) is connected with charging mouth of pipe silk, and refluxing opening (4) is connected with the reflux line silk; Outlet (8) is in valve seat (7) lower end.
The thermal medium groove runner (11) of said valve body (3) outer wall processing twice UNICOM; Secondary operations formed the light face after the notch of thermal medium groove runner (11) was added a cover welded closure; Still keep valve body (3) cylindrical shape; Thermal medium groove runner (11) two ends are set up import and outlet separately, are connected with the heat medium pipe filament respectively with flexible pipe.
Said inlet (12) is distributed in cylinder shape valve (3) side with refluxing opening (4), is an angle of 90 degrees along circumference.
Said outlet (8) is processed to form profile and is up-narrow and down-wide bell mouth shape, and it highly is 10mm cylindrical (9) that terminal inboard is processed as.
Said spool (5) middle part is provided with opening slot (6).
The utlity model has following advantage:
1. simple and reasonable for structure, volume is little, in light weight, consumptive material is few;
2. the valve body inlet is connected with material pipeline straight line, raises the efficiency;
3. valve outlet becomes bell mouth shape, and the instantly slowing down flow velocity is avoided spraying and splashed, and conservation, protection environment the more important thing is to guarantee the casting precision;
4. the valve body skin is provided with steam heater, both can adjust material liquid wax temperature at any time, can occur when preventing just to start shooting stopping up to the valve body preheating before start again.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Fig. 1 is new-type casting valve cross-sectional schematic;
Fig. 2 is that the cylinder valve volume surrounding is along circumference expanding map.
Picture in picture mark: cylinder 1, valve rod 2, valve body 3, refluxing opening 4, spool 5, opening slot 6, valve seat 7, outlet 8, cylindrical 9, fluid director 10, thermal medium groove runner 11, inlet 12.
Embodiment
As shown in Figure 1; The casting valve is combined by cylinder 1, valve rod 2, valve body 3, spool 5 and valve seat 7, and cylinder 1 is connected with valve rod 2 upper ends, and valve rod 2 is the rhabodoids with the processing of 304 stainless steels; Bottom in valve body 3, valve rod 2 lower ends; The end studs with spool 5, and spool 5 middle parts are provided with opening slot 6, mainly is in order to alleviate spool 5 weight; Move through the upper and lower of spool 5, make valve body 3 inlet 12 or with outlet 8 UNICOMs or with refluxing opening 4 UNICOMs; Valve body 3 lower ends are processed to form valve seat 7.
Valve body 3 is the cylindrical three way valvies that are processed into φ 100mm * 100mm with common 304 stainless steels, and threeway is respectively inlet 12, outlet 8 and refluxing opening 4 on the valve body 3, is clear opening; Inlet 12 is distributed in corresponding side, valve body 3 middle and upper parts with refluxing opening 4, is an angle of 90 degrees along circumference; Inlet 12 is connected with the charging mouth of pipe, and refluxing opening 4 is connected with reflux line; Outlet 8 is processed to form bell mouth shape from top to bottom in valve seat 7 lower ends, guarantees that liquid wax goes downstream not hang on outlet 8 inwalls, exports 8 bottoms and is processed into highly to cylindrical 9, the inwall of 10mm along inwall and processes thread, is connected with fluid director 10.
Thermal medium groove runner 11 as shown in Figure 2, that valve body 3 outer walls processing twice are communicated with, the notch place of thermal medium groove runner 11 adds a cover welded closure; Secondary operations forms the light face, still keeps valve body 3 cylindrical shapes, and thermal medium groove runner 11 two ends are set up import and outlet separately; Connect with flexible pipe and thermal medium pipeline; Use for the thermal medium circulation, specially valve body 3 is heated in good time, to guarantee that liquid wax keeps constant temperature in the valve body 3; Can occur when preventing just to start shooting stopping up to valve body 3 preheatings before start again.
During the work of casting valve, realize opening or closing of casting valve by spool 5.When cylinder 1 drives valve rod 2 and upwards promotes, move on the spool 5, separate with valve seat 7 and open, make inlet 12 and outlet 8 UNICOMs, liquid wax flows in the corresponding cake wax through outlet 8 fluid director 10 of flowing through at regular time and quantity thus; When valve rod 2 relied on power that cylinders 1 give to lower slider, spool 5 was closed with valve seat 7, enter the mouth this moment 12 with refluxing opening 4 UNICOMs, liquid wax flows to the circulation basin through reflux line.
