Embodiment
With specific embodiment the utility model is further elaborated below, but embodiment only is used for explanation, does not limit scope of invention.
Embodiment 1:
As Fig. 1, Fig. 2, shown in Figure 3, a kind of gas allocation set apparatus for converting of oxygen gas supersonic spray coating equipment mainly comprises: inlet end 1, body 2, a plurality of electromagnetic switch valve 3～N, outlet side damping piece 8, gas flow gate ring 9, electromagnetic valve core 10, valve pocket 11; Installation, the boot sequence of each magnetic valve and the time of switch of a plurality of magnetic valve 3～N on body 2 is controlled by PLC.
In the automatic ignition process of oxygen gas supersonic spray coating, all kinds of gases (oxygen, combustion gas, pressurized air) that spraying is used, enter by inlet end 1, under the control of PLC controller, magnetic valve 3～N carries out the substep startup and turn-offs, thereby realizes that high-pressure gas after fired outside, changes the stable burning of the high pressure conditions in the rifle over to smoothly, obtain having ultrasonic burning flame stream, realize hypersonic flame spraying.
This device solves gas distributing valve is in the past installed complexity, leakage and the high shortcoming of failure rate, has simplified the equipment installation and has reduced the volume of gas distribution assembly and the weight of distribution member.To the ON time of electromagnetic switch valve and the control of order, make simple more, the reliable and miniaturization of operation of oxygen gas supersonic speed equipment by the PLC controller.
Embodiment 2:
One-way valve to the mode of the control of gas is: a kind of working gas enters from inlet end 1, electromagnetic valve core 10 by a solenoid controlled, flow through the gas flow gate ring 9 of restriction gas flow, by the outlet side damping piece 8 powder spares of damping stabilization are arranged, enter spray gun again.At hypersonic flame spraying, can high-pressure gas and oxygen produce ultrasonic flame in the time of burning, its multiple gases could stable burning at high pressure conditions, must guarantee the conversion of low flow velocity flame to supersonic flame by the action of multipath gas threshold switch time, order.Under the control of PLC controller, combustion gas, oxygen, pressurized air, powder delivering gas are by the different switching times of magnetic valve 3～N on a plurality of combination valves island and the control of order, make the external combustion flame that makes a fire change the supersonic flame of the high pressure conditions in the rifle over to, thereby realize the spraying coating process of supersonic flame.
Ignition operation gas can be (single channel gas trap island) shown in the following table from the external combustion of the beginning flame that makes a fire step by step to the gas control process of supersonic flame:
Finishing external combustion the make a fire conversion of flame to rifle in supersonic flame in 4* (N-1) step as the magnetic valve on 4 valve islands (controlling oxygen, hydrogen, propane, nitrogen respectively) under the commander of PLC, 4*N goes on foot Close All, open the main valve of working gas pipeline simultaneously, carry out hypersonic flame spraying.
Use the valve island device that makes up to significantly reduce the quantity of gas piping as can be seen from the above table, if 6 magnetic valves are installed on the single valve island, make 6 road gas pipings in the past be reduced to 1 road gas piping, 4 groups of valve islands are reduced to 4 road pipelines from 24 road gas pipings, particularly the erection joint of pipeline also is reduced to 8 contacts from 24 contacts, and the air seal performance and the safety performance of supersonic velocity flame plating equipment are greatly improved.
