Description
Technical field:
The utility model relates to a kind of interior curing glass steel conduit heating control apparatus.
Background technology:
Nineteen sixties, the U.S. at first developed high-pressure fiberglass pipe, and the instead of steel pipe is used for oil collector and delivery pipe road, had obtained good economic benefit and social benefit.China initial stage of tertiary oil recovery from external introduction high-pressure glass fibre reinforced plastic pipe, to solve the etching problem of polymkeric substance to steel pipe.Traditional GRP pipe adopts the equipment (wrapping machine, curing oven and ingot stripper) of three platform independent to carry out pipeline winding, curing and the demoulding usually; adopt the outer curing process that heats body and core from outside to inside that the FRP pipeline is cured, this has increased equipment cost and production cost.And pipeline when in curing oven, solidifying heat transfer efficiency low, solidification temperature regulation and control difficulty, body solidifies of poor quality, therefore outer curing process is difficult for the efficient suitability for industrialized production of realization pressure piping.
Summary of the invention:
The purpose of this utility model is to overcome deficiency of the prior art, a kind of interior curing glass steel conduit Steam Heating control device is provided, can on the heating and cooling program, can do meticulous adjusting and control, to improve the quality of products, reduce cost, realize full-automatic production, enhance productivity greatly.
Above-mentioned purpose realizes by following technical scheme:
Interior curing glass steel conduit Steam Heating control device, its composition comprises: with the centralized control unit PLC of control program, described centralized control unit PLC connects touch-screen and Continental Europe 2404 type temp controlled meters, described Continental Europe 2404 type temp controlled meters connect temperature sensor and two variable valve, described centralized control unit PLC comprises power supply, CPU and the switching value input block that is attached thereto thereof, switching value output unit and analog input unit, described switching value input block connects the input switch signal, described switching value output unit connects auxiliary reclay, described auxiliary reclay connects the solenoid control switch, and described analog input unit connects pressure transducer.
Beneficial effect:
1. the utility model adopts thermometer that temperature is carried out PID control, by setting to each stage parameter of temp controlled meter, and can be more accurate to the control in each stage of temperature.
2. the utility model has used Continental Europe 2404 type temp controlled meters in control system, has realized the automatic adjusting of PID, makes temperature-rise period not have overshoot, and the process of heating is more stable.
3. it is more even that the utility model makes the curing of GRP pipe, and set time is short, and it is low to consume energy, GRP pipe evenness of wall thickness, intensity consistance, and presentation quality all is improved.
4. the utility model can make the operator that heating process is got more information about by the control of touch screen, and convenient operates.Simple to operate, easy to use, increase work efficiency.
