Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of high-presure polyurethane foaming machine, as shown in figures 1 and 3, two the feedstock circulation systems 7 comprising rifle head 1 and be connected with rifle head 1 respectively; Each described feedstock circulation system 7 comprises batch can 2, material pump 3, high-low pressure reversal valve 4 and testing valve 5; Described batch can 2 is connected with material pump 3 by pipeline; Described high-low pressure reversal valve 4 one end is by the discharge end of pipeline binder pump 3; Described testing valve 5 is provided with test port 6, is also connected with batch can 2, rifle head 1 and high-low pressure reversal valve 4 respectively by pipeline in addition.
Wherein, as shown in Figure 2, described rifle head 1 comprises with symmetrically arranged two charging apertures 12 on the rifle body 8 of jet 11, the piston rod 9 of the interior setting of rifle body 8 and rifle body 8; Described piston rod 9 front end is provided with the groove 91 of energy conducting two charging aperture 12.It should be noted that, groove 91 is the endless grooves can established along piston rod 9 circumferencial direction, and upper and lower two charging apertures 12 all therewith groove are connected.
Wherein, described testing valve 5 is cross valve, and its import is connected with high-low pressure reversal valve 5 by pipeline, three outlet in one as test port 6, one is connected with rifle body 8 by pipeline, one is connected with batch can 2 by pipeline.It should be noted that, the import of this cross valve can only export and connects with one, can not connect the outlet of two (and more than) simultaneously.
Wherein, the pipeline be connected with described rifle body 8 is rubber hose, facilitates outdoor site operation, flexibly mobile, workable.
Wherein, the pipeline of described feedstock circulation system 7 is provided with pressure-detecting device 10.Pressure tap on described pressure-detecting device 10 is provided with Pressure gauge 101, can real-time monitored to the pressure in pipeline.
Wherein, described rifle head 1 is by Hydraulic Station 110 control action, and Hydraulic Station 110 can external independent connection, also can, when dispatching from the factory, being installed in the machine, flexible arrangement, when client has Hydraulic Station, can saving purchase cost.
