Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described: as shown in Figure 1, the special quantity control valve of new type high temperature liquid wax, be made up of guiding valve zoarium 1, latch 2, valve seat 3, latch guide way 4, electric cylinder 5, it is characterized in that: coordinated by flange and center hole in the front end of valve seat 3 and guiding valve zoarium 1 is installed, coordinated by flange and central bore in the rear end of valve seat and latch guide way 4 is installed, electricity cylinder 5 is connected with latch guide way 4 by flange, and the piston rod of electric cylinder 5 is connected with latch; Latch guide rod part is arranged in latch guide way center hole, can slide therein, the conical tip of latch 2 be inserted into the taper pin guide pin bushing 1.4 of guiding valve zoarium 1 inner and with its central coaxial.
Wherein guiding valve zoarium 1 is made up of 1.1 sleeve valve case, 1.2 sliding spools, 1.3 springs, 1.4 taper pin guide pin bushings, 1.5 flow orifice plates, 1.6 joints, 1.7 nuts, 1.8 connecting bolts, 1.9 pads, 1.10 zero RunddichtringOs, 1.11 square RunddichtringOs, wherein in the center hole of sleeve valve case 1.1, from right to left sliding spool 1.2, spring 1.3 and flow orifice plate 1.5 are installed successively, and sliding spool or the centring sleeve of spring; Joint 1.6 is connected with sleeve valve case opening end by screw thread, is installed with zero RunddichtringO 1.10 at joint 1.6 and the end face of sleeve valve case 1.1; Nut 1.7 is threaded connection the one end at joint, tightly locking for connecting wax conveying tube Lu Shibei; Taper pin guide pin bushing 1.4 is arranged on the right-hand member of sleeve valve case, and is connected by center hole positioning threads; Zero RunddichtringO 1.10 is embedded in the right-hand member dovetail groove of taper pin guide pin bushing; Connecting bolt 1.8 and pad 1.9 are for being connected guiding valve fit 1 and valve seat 3.
Latch 2 is made up of 2.1 taper pins and 2.2 guide rods, two parts; Wherein taper pin 2.1 is connected with guide rod 2.2 by internal thread, and makes the two coaxial by straight mouth location.
Valve seat 3 is made up of 3.1 mounting flange I, 3.2 inlet flanges, 3.3 valve bodies, 3.4 mounting flanges II; Wherein mounting flange I 3.1 leans against left end face by inner hole sleeve in the outer ring of valve body 3.3; Inlet flange 3.2 inserts and is welded in areole to the left in the middle part of valve body, forms threeway cavity with valve body; Mounting flange II 3.4 is enclosed within the outer ring of valve body 3.3 by center hole and its right end face is concordant with it, and the two welds together.
Latch guide way 4 by 4.1 back-up rings, 4.2 paraffin cutting rings, 4.3 hole seal rings, 4.4 axle combined seal rings, 4.5 guide pin bushings, 4.6 seal rings, 4.7 mounting flanges III totally seven parts form.Its mounting structure is: be installed with axle combined seal ring 4.4 at the front end center cavity inner bottom part of guide pin bushing 4.5, in the outer ring groove of axle combined seal ring, be installed with hole seal ring 4.3; Have on the left of combined seal ring at axle and paraffin cutting ring 4.2 is installed; Back-up ring 4.1 is inlayed in the endoporus groove of the left side of paraffin cutting ring and the left front end of guide pin bushing; Be connected with the endoporus of mounting flange 4.7 by the straight mouth of flange at the right-hand member of guide pin bushing; Seal ring 4.6 is embedded in the groove of guide pin bushing its right end face, is clipped between guide pin bushing and mounting flange both ends of the surface.
Electricity cylinder 5 is the linear motion units adopting servo drive control.It is exported by the flow controlled coordinating between taper pin 2.1 with taper pin guide pin bushing 1.4 in the unit time and the opening and closedown of valve; Carry out output flow regulable control.
Carry out regulation output liquid pressure by the sliding spool 1.2 in guiding valve zoarium 1 and flow orifice plate 1.5, delivery pressure can be regulated at any time.
Sleeve valve case 1.1 has a discharge orifice, and when valve open has flow to export, discharge orifice is covered by sliding spool 1.2, ensures output pipe system No leakage; When the valve is closed, to be removed by valve core 1.2 by automatically reseting of spring 1.3, discharge orifice exposes, and liquid unnecessary in pipeline flows out from floss hole; Wax automatic-discharging more than output pipe can be made.
The control of valve adopts servo electricity cylinder 5 or electric pushrod, can be carried out the opening time of control valve like this by electric program.Accomplish valve opening time parametrization auto-adjustment control.
The guide pin bushing 4.5 of taper pin guide way 4 has left an overflow hole.If the wax liquid in valve seat 3.3 die cavity because poorly sealed reflux is to taper pin guide way rear portion, is then discharged by this overflow hole, be unlikely to infiltrate the use affecting electric cylinder in electric cylinder 5; Have effectively achieved residual wax relief function.
During work, control valve is connected with defeated wax pressure main by inlet flange, is filled with the liquid wax with certain pressure in the die cavity of valve seat 3.
When there being liquid to export, control valve is in open mode, now drive latch 2 to retreat by servo electricity cylinder 5 to extract in taper pin guide pin bushing 4.5, at this moment there is an annular space between taper pin 2.1 and taper pin guide pin bushing 1.4, liquid wax just flows in the cavity of guiding valve zoarium 1 along anchor ring hole system, space through sliding spool 1.2, spring 1.3, flow orifice plate 1.5, joint 1.6 enters in wax conveying tube road, and finally reaches under the effect of the pressure in the filling wax cavity on pipeline top.Sliding spool 1.2 in sleeve valve case 1.1 remains on the die cavity end of sleeve valve case 1.1 under the effect of spring 1.3, the de-waxing hole on sleeve valve case 1.1 sidewall is blocked, thus when ensureing defeated wax, path does not leak.Flow orifice plate 1.5 is used to regulation output fluid pressure.The degree of depth inserted between taper pin 2.1 and taper pin guide pin bushing 1.4 determines the area of the annular hole formed therebetween, also just determine the fluid flow passed through, and the degree of depth that taper pin 2.1 inserts is the Stroke Control by servo electricity cylinder 5.
When control valve does not have liquid to export, control valve is in closed condition, now latch 2.1 is driven to advance by servo electricity cylinder 5, latch 2.1 is allowed to be inserted in latch guide pin bushing 1.4 completely, and the end face of the straight mouth end face of latch 2.1 and latch guide pin bushing 1.4 precision is fitted, end face zero RunddichtringO 1.10 is crushed out of shape and realizes sealing.Simultaneously in the process that taper pin 2.1 is inserted in guiding valve zoarium 1, sliding spool 1.2 forward slip under the promotion of taper pin 2.1, exposes the de-waxing hole of sleeve valve case 1.1 side, and the remaining wax at this moment in wax conveying tube road just flows out from de-waxing hole under gravity.The object of discharging remaining wax in pipeline when the system cools down more than wax solidification, cause pipeline blockage and be not easy dredging.As shown in Figure 2, the special quantity control valve of new type high temperature liquid wax is arranged on bodywork cavity and fills with on the main line of wax equipment, and point bilateral symmetry is arranged, generally one-sidedly installs 8 groups, and often organize 4 cover quantity control valves, 64 cover quantity control valves installed altogether by complete equipment.The liquid wax with certain pressure is filled with in main line.Main line is arranged on the both sides of filling with wax pan.The supply of liquid wax exports by for wax pump, is arranged on storage wax pan for wax pump.
The output terminal of quantity control valve is connected with needing the quantitative bodywork cavity for wax.When defeated wax system works (when existing vehicle body needs to fill with wax), servo electricity cylinder 5 starts makes valve open, at this moment the wax liquid in defeated wax main line will enter in valve valve seat 3 die cavity along valve inlet, and is entered in vehicle body filling wax cavity along output pipe by a series of assemblies arrival delivery outlets of guiding valve zoarium 1.The flow that 64 valves that system is installed export is different, and this adjustment is realized by servo electricity cylinder 5.
