Description of drawings
Fig. 1 is the structural representation of the embodiment of the utility model.
The specific embodiment
High pressure mixing is to the embodiment of flushing device, and is as shown in Figure 1, comprises rifle head 15; Offer tapping channel 16 on the lower surface of rifle head; Offer two feeding-passages 7,9 on the upper surface of rifle head, feeding-passage 7,9 is arranged on two high pressure nozzles, 6, the 10 corresponding connections on the rifle head with spout towards relative fixed respectively, and described high pressure nozzle comprises cavity 11; Described spout is arranged on the front end of cavity 11; The cavity inner wall of spout rear end is provided with the conical surface, is provided with in the cavity to move with the inner wall sealing of cavity 11 to cooperate the push rod 17 that is used to open and close spout, and the conehead that push rod 17 is joined through the conical surface seal with said spout rear end of its front end setting does not seal spout when the rifle head is not worked; Putting back-end is provided with back-moving spring 5; Article two, feeding-passage is connected with the cavity of the push rod front end of high pressure nozzle respectively, and the rear end of high pressure nozzle is equipped with the single-acting pneumatic cylinder, and the single-acting pneumatic cylinder comprises cylinder body; Cylinder body by the open rearward end front end through end plate closes cylindrical shell 3 and revolve the cover 1 that is located at the cartridge openings end and form; Cover 1 is provided with air inlet 14, and said end plate is provided with gas outlet 18, is provided with piston 2 in the cylindrical shell of cylinder body; The sealing ring that is provided with between the cylinder inboard wall of piston 2 through its outer peripheral face and cylindrical shell moves with the cylinder body sealing and cooperates; The boss that the single-acting pneumatic cylinder is convexly equipped with through its barrel front end plugs the rear end of the cavity that is fixed on high pressure nozzle, offers the through hole that cylindrical shell is connected with cavity on the boss, fixedly installs on the front end face of said piston to be useful on to promote the piston mandril that push rod moves when moving with piston 2; Described piston mandril passes described through hole and stretches out the cylinder body of single-acting pneumatic cylinder and extend in the cavity of high pressure nozzle, is communicated with between two spouts of high pressure nozzle to be provided with the mixing chamber 8 that is connected with tapping channel 16.
The foregoing description in use; At first this device is connected to the terminal of high pressure foaming machine feeding system; End of line before just urethane raw mixes, with high pressure produce urethane raw---the tip line of MDI and POL is connected to the charging aperture place of two feeding-passages, and guarantee that 7 and 9 places seal strictness and do not leak material; When not starting the high pressure feeding system; Under the effect of the returning spring of both sides, the conehead of left and right sides push rod front end and the conical surface of spout rear end fit tightly together, make two kinds of raw materials of MDI and POL not leak from spout; Strict guarantee because material crystal phenomenon before the high pressure mixing not, insert compressed air at the air inlet place of the single-acting pneumatic cylinder of both sides.
Start high pressure foaming machine during work, when treating that system pressure reaches manufacturing technique requirent, self-corresponding feeding-passage enters in the cavity of push rod front end of each self-corresponding high pressure nozzle the raw material of certain pressure through each respectively in MDI and POL tip line; Under the effect of feed pressure, the axial compressive force that the push rod of both sides will overcome spring moves backward, owing in the footpath of push rod sealing ring is installed upward; Raw material can not revealed herein, has well guaranteed the pressure and the flow of raw material system, and the high pressure feedstock of both sides gets in the mixing chamber that is provided with between the high pressure nozzle through the spout of high pressure nozzle respectively simultaneously; Owing to the raw material of high pressure sharply sprays at spout, the high-pressure atomization collision that liquidates is connected to the outside through tapping channel at the mixing chamber place; And can MDI and POL be mixed very fully, the pressure of single-acting pneumatic cylinder air inlet that can be through the online adjustment left and right sides makes pressure be delivered on the push rod through piston; When the pressure of the raw material of the spout of high pressure nozzle ejection diminishes; The air inlet of single-acting pneumatic cylinder, gas pressure promote piston forward and move, and piston mandril promotes push rod and moves forward; Make the pressure of the raw material of high pressure nozzle spout ejection increase to the pressure of regulation; When the pressure of the raw material of the spout of high pressure nozzle ejection increased, the pressure of single-acting pneumatic cylinder air inlet reduces made piston move certain distance backward, and the active force that the raw material of high pressure nozzle spout ejection will overcome spring moves push rod backward; When the pressure of raw material that moves to the spout ejection of high pressure nozzle when push rod reaches the pressure of regulation; The piston mandril of single-acting pneumatic cylinder withstands push rod, and the pressure stability of raw material that makes the spout place can well guarantee the stability of feed pressure like this in the force value of regulation; Make that the foam of continuous lines slabstock polyurethane is fine and smooth more, and effectively improve the flatness and stability of polyurethane core.
In other embodiment; Described single-acting pneumatic cylinder can also be arranged to front opening, the structure of back-end closure, and directly spiral-lock is in the rear end of described high pressure nozzle; Described air inlet is arranged on the end plate of back-end closure, and described gas outlet is arranged on the front end of cylinder body.
In other embodiment, described single-acting pneumatic cylinder can also replace to hydraulic cylinder or the pneumatic cylinder except that the single-acting pneumatic cylinder.
