Detailed description of the invention
As described in Figure 1, the utility model expansion joint shaped by fluid pressure automaton, comprises pressuring pump group 1, switch valve 2, check-valves 3, pressure regulating device 4, plc data processor 5, external pressure equipment 7, rangefinder 8, pipe embryo 9 and mould 10.Pressuring pump group 1 is made up of a blade low-lift pump and a piston high-pressure pump, high output pressure 40MPa, maximum output flow 750L/min.Switch valve 2 is that to be fixed on 500mm × 500mm, a thickness by the magnetic valve of two DN25mm and a DN20mm be that 50mm, material are on 304 stainless installing plates, the both sides of installing plate process liquid-inlet and outlet, at the check-valves of a DN50mm of liquid outlet fixed installation.Pressure regulating device is made up of electromagnetic relief valve and a pressure sensor of two DN25mm.
On rangefinder 8, magnet is housed, is fixedly mounted on the lower table face of mould 10 upper end-face edges or external pressurized equipment 7, convenient operation, three rangefinders 8 are arranged in same level.On switch board, install plc data processor 5 and control flow 6, and operation sequence is write to plc data processor 5.By the control module of the control circuit access PLC of external pressure equipment.
Be connected suppressing the outlet of pumping plant and the import of the switch valve stainless steel tube of long 1 meter of Φ 50mm × 6mm, be connected with the stainless steel tube of 0.3 meter of Φ 50mm × 6mm from the outlet of check-valves and the import of pressure regulating device, the outlet of pressure regulating device is connected with the inlet of pipe embryo with the high-pressure hose of DN32mm again.
On external pressure equipment 7, install and need the pipe embryo of compacting 9 and corresponding mould 10, and the upper and lower port of pipe is sealed.
Operating personnel's input on operation screen needs pressure and the stroke of compacted products, start pressuring pump group by plc data processor, low-voltage solenoid valve, electromagnetic relief valve, and start working, liquid enters the inside of pipe embryo by pressuring pump, because pipe inside is hermetically-sealed construction, after filling, internal liquid presses in generation, the size of force value is by the pressure sensor being connected on pipeline, the numerical value of real-time pressure is passed to plc data processor, in the time that expansion joint internal pressure is greater than a certain force value, plc data processor can cut out low-voltage solenoid valve automatically, and open high-pressure solenoid valve simultaneously.When internal pressure reaches after setting pressure, plc data processor can cut out pressuring pump group and magnetic valve, connect external pressure equipment, external pressure equipment is moved downward, moving downward in process, because pipe embryo internal volume diminishes, pressure raises, electromagnetic relief valve is started working, the liquid of expansion joint inside is outwards discharged, make the pressure of pipe embryo inside remain on setting pressure, be positioned at pipe three groups of infrared ambulators suitable for reading, can on control flow, show the variation of pipe length dimension, if the numerical value of three rangefinder demonstrations is consistent in change procedure, represent that pipe is parallel descending, if there is one group of numerical value to change, the axiality generation deviation of expansion joint is described, device can automatically be adjusted pressure and repair, make the each position of expansion joint DL synchronization, the precision of final expansion joint can reach standard-required.
On the control flow of PLC, after setup pressure value and pressing stroke, open play button, equipment enters duty.In the time that fluid pressure also has 2MPa from setting value, mass flow blade low-lift pump quits work, the work of low discharge piston high-pressure pump, make it distortion to the inner slowly pressurization of expansion joint, in the time that pressure reaches setting value, pump group is closed, while press device starts pressurization and moves down, in the process pressing down, when internal pressure is higher than when setting value, pressure regulating device can carry out pressure release to pipe embryo inside, makes it to keep the stable of internal pressure, and after press device displacement reaches setting numerical value, press quits work, expansion joint internal pressure is all laid down simultaneously, and product has been suppressed.
Although the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Under the utility model, in technical field, have and conventionally know the knowledgeable, not departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is when being as the criterion depending on claims person of defining.
