Technical field the present invention relates to a kind of water separator of steam pipe system.
Background technology is present, and the drain valve kind of using in steam pipe system is a lot, all is that entrance point and endpiece are connected on the pipe network basically, and is closed state, is difficult to detect temperature and the flow that drain valve truly discharges condensate water like this.For the drain valve of some poor-performings, even it causes a large amount of steam leakages, also can't in time find, not only cause energy dissipation, but also can bring economic loss to manufacturing enterprise.
Summary of the invention the object of the present invention is to provide a kind of steam-water separation effect good, can monitor the Automatic steam trap Trap discharging condensate temperature flow monitoring device of condensate temperature and flow simultaneously again.
The present invention mainly comprises drain valve and mechanism for monitoring, wherein, this drain valve can be existing drain valve, but on the close housing of fluid egress point of drain valve, be provided with the screw that is communicated with valve pocket, be the thermopair hole, an end of the thermopair that is threaded on it, the other end of this thermopair is positioned on the passage of drain valve inner fluid.Preferably drain valve has two ends to manage blue cavity housing, and preferably the inlet end of housing is established the slotted eye of diameter greater than the valve pocket aperture, and screen pack places on the boss of slotted eye bottom, and preferably screen pack is arch.On the above-mentioned sidewall of establishing the screen pack slotted eye, be provided with the through hole that passes valve pocket, i.e. mudhole, the other end of this through hole is provided with the blowdown plug.Being provided with the induction movement in above-mentioned drain valve housing chamber is corrugated tube, and this induction movement is with retracing spring towards the front portion of housing inlet, and the one end is stuck on the induction movement, and the other end is stuck on the interior boss of valve pocket.And the front end of induction movement can contact with the central through hole of polytetrafluoroethylene ring in being located at valve pocket, and with its sealing.Best, be provided with the annular metal sheath between this polytetrafluoroethylene ring outside and the valve pocket.End in contact before the afterbody of above-mentioned induction movement and the set screw, this set screw are passed and are threaded on the center screw that blocks up behind the valve.Be connected with the through hole whorl of intracavity inter-connection on the stifled and drain valve housing behind the above-mentioned valve, blocking up behind this valve can be with this through hole movable sealing.Preferably stifled outside is provided with blanking cover behind the valve that is threaded behind this valve.At above-mentioned induction movement outer mask guide pipe is arranged, the cylinder rear end that this wall is provided with some through holes places in the seam that blocks up behind the valve, and front end places in the valve pocket groove corresponding with it.(it is to distinguish successively through order by fluid in above-mentioned drain valve induction movement back, arriving first part is the front, the back is the back to part, housing down together) is provided with two relative screws that are communicated with valve pocket, it is form that this screw is provided with the transparent material layer corresponding with it, be provided with becket in this form outside, its outer wall is threaded with above-mentioned screw.In addition in the form back near on the housing of fluid egress point, be provided with the another screw that is communicated with valve pocket, i.e. thermopair hole, an end of the thermopair that is threaded on it, the other end of this thermopair is positioned at drain valve.
Mechanism for monitoring of the present invention mainly includes: temperature signal collection card, sub-programmable controller, Industrial Ethernet or wireless router, wireless network and master station.Wherein, temperature sensor and temperature signal collection card adopt hardwire directly to be connected, reducing the intermediate link of signal transmission, stable, reliably, the signal of collection site temperature sensor in real time.The plurality of temperature data acquisition card that links to each other with each temperature sensor becomes the signals collecting station by the subrack set, and it inserts in the sub-programmable controller PLC.The sub-programmable controller PLC at this signals collecting station includes power supply, central processing unit CPU, storer, input/output interface circuit and has counting, location and the functional module of communicating by letter, therefore can finish signals collecting, processing and record, as the conversion of engineering value, functions such as out-of-limit differentiation and self-checking alarming.When signals collecting ground and master station when nearer, transmit the signal wired network of gathering, promptly this sub-programmable controller PLC Industrial Ethernet links to each other with the monitor supervision platform of master station; When signals collecting ground and master station apart from each other, transmit the signal wireless network of gathering, being about to this sub-programmable controller PLC is that router DTU is connected by serial communication and 3G radio data-transmission equipment, wireless router DTU sends data by 3G wireless network GPRS then, these data are carried out decoding processing through GPRS network air interface functional module to data, convert the form that transmits in the public network data to, GPRS radio data network by China Telecom transmits, finally be sent to master station, this master station comprises programmable controller PLC and computing machine.The instructions that the while master station sends also is by it data to be issued sub-programmable controller PLC again by 3G wireless network GPRS.
The course of work of the present invention is as follows: the induction movement in the drain valve be heated after expansion and axial elongation.When come in from the drain valve import be steam the time because the vapor (steam) temperature height, the induction movement of elongation can not leak steam the polytetrafluoroethylene ring shutoff; When come in from the drain valve import be condensate water the time because condensate temperature is low, the induction movement is shunk, break away from polytetrafluoroethylene ring, condensate water is discharged from their gap, with steam and condensed moisture from.Induction movement back is provided with visor and temperature sensor, visor can observe the flow of condensate water, temperature sensor can be measured the temperature of condensate water, and pass to master station by temperature signal collection card, sub-programmable controller, wireless router, wireless network, on the display of master station, can see the temperature of the condensate water that each drain valve is discharged.Under the normal condition, the temperature basically identical of the condensate water that numerous drain valves are discharged, be 75-85 ℃ (special requirement exception), when the temperature of the condensate water of discharging far below said temperature or be higher than said temperature far away, assert that then the hydrophobic pipeline that this drain valve relates to breaks down, need maintenance in time to fix a breakdown.
The present invention compared with prior art has following advantage:
1, can monitor at any time the condensate temperature and the flow of the discharging of the drain valve that works online, can in time find the fault of online pipe network, solve the closed circuit steam pipe system unknowable problem of situation that works online by the data that monitor.
2, in time pinpoint the problems, in time solve, the control steam leakage is approximately zero, has reduced a large amount of economic losses and energy dissipation that each enterprise causes because of steam leakage.
3, the operator does not spend the scene, not only save time, laborsaving, and high efficiency, also can make the management of enterprise's this respect step into modernization.
