16 electrical connections, can control opening or closing for the second valve 16, it is notable that in the present embodiment, work as second temperature
When the temperature value that sensor 13 detects is less than some value E, control piece 14 receives the signal of the transmission of second temperature sensor 13
When, which will control the unlatching of the second valve 16, detect the second pipeline section further according to each first temperature sensor 12
Actual temp value on 112 controls the working condition of the first valve 15 on each second pipeline section 112.
When the temperature value that second temperature sensor 13 detects is greater than some value F, illustrate to heat-preserving equipment 21 in this ring
Normal work is able to carry out at a temperature of border, which does not have to carry out heat preservation heat tracing operation, at this point, control piece
14 when receiving the signal of the sending of second temperature sensor 13, which will be such that the second valve 16 closes.It is understood that
, the first valve 15 on each second pipeline section 112 is in close state at this time.It is worth noting that, second temperature at this time
Sensor 13 does not stop working, and the temperature of lasting detection environment, the temperature value of detection are less than by second temperature sensor 13
When some value E, control piece 14 reopens the second valve 16 again, carries out heat preservation heat tracing operation.
It is understood that in the present embodiment, opening or closing for the second valve 16 is determined by the temperature of environment,
There is no directly contact with the size of the temperature of steam in heat tracing pipe 11.
Specifically, control piece 14 is as shown in Figure 3 to the control flow chart of the first valve 15 on the second pipeline section 112, comprising:
S11: maximum value A and minimum value B of the setting about temperature in control piece 14；
S12: detect the temperature value C of the second pipeline section 112 compared with A carries out size the first temperature sensor 12；
If C is greater than A, S13 is carried out: closing the first valve 15；
If C is less than or equal to A, S14 is carried out: by C compared with B carries out size；
If C is less than B, S15 is carried out: opening the first valve 15；
If C is greater than or equal to B, then carries out S12: the first temperature sensor 12 is detected to the temperature of the second pipeline section 112
Angle value C is compared with A carries out size.
What is so recycled is detected and is adjusted to the vapor (steam) temperature in the second pipeline section 112, can not only treat guarantor in time
Warm equipment 21 carries out tracing thermal-insulating operation, and can effectively save steam usage amount, improves the steam tracing system 100
Economy.
It is worth noting that, in the present embodiment, the temperature that control piece 14 can also be detected according to the first temperature sensor 12
The difference for the temperature value that angle value and second temperature sensor 13 detect adjusts the openings of sizes of the first valve 15, to adjust companion
The size of steam flow in heat pipe 11, can be effective energy saving.Specifically, pair of the size of the size and opening of difference
It should be related to, staff can test and determine according to the actual situation.
It should be noted that the specific size of above-mentioned A, B, E, F can be arranged in staff according to the actual situation, here
It will not enumerate.
Fig. 1 is please referred to, in the present embodiment, the first temperature sensor 12 is abutted with the outer wall of the second pipeline section 112, and first
The position of temperature sensor 12 is corresponding with the position of output section of the second pipeline section 112.
It should be noted that the first temperature sensor 12 is abutted with the outer wall of the second pipeline section 112 more accurately to be detected
The temperature of steam in second pipeline section 112.
In the present embodiment, the position of the first valve 15 and the position of the first temperature sensor 12 with the second pipeline section 112
Output section position it is corresponding, and the first valve 15 relative to the first temperature sensor 12 close to the input unit of the second pipeline section 112.
It is understood that the position of the first temperature sensor 12 is located proximate to the second pipeline section relative to the first valve 15
The opening of 112 output section enables 12 accurate detection of the first temperature sensor to the output section of the second pipeline section 112
Temperature, meanwhile, after the first valve 15 opens or closes, the first temperature sensor 12 can also detect the second pipe at the first time
The variation of the temperature of the output section of section 112 sends temperature signal to control piece 14 in time, to the temperature inside the second pipeline section 112
It is monitored in real time, timely on or off tracing thermal-insulating operation.
In the present embodiment, steam tracing system 100 further includes warning device 17, and warning device 17 is electrically connected with control piece 14
It connects.
It should be noted that warning device 17 can alarm in the following two cases；
Situation 1: when the first temperature sensor 12 detects that the temperature value of the second pipeline section 112 is preset most greater than control piece 14
Big alarming value or when being less than 14 preset minimum alarm value of control piece, control piece 14 can issue the finger of alarm to warning device 17
It enables, reduces the steam tracing system 100 and the probability of accident occur.
Situation 2: it is lower than when the first temperature sensor 12 detects that the temperature value of the second pipeline section 112 continues for an extended period of time
When some value, even if the temperature value of first temperature sensor 12 detection still continues relatively low, control after the unlatching of the first valve 15
Such case can be judged as inside heat tracing pipe 11 pipeline blockage occur by part 14, at this point, control piece 14 also can be to warning device 17
Issue alarm command.
It should be noted that the alarm sound of warning device 17 in case 1 is different from alarm sound in case 2,
Staff can carry out specific inspection and maintenance according to specific alarm sound, be conducive to the work effect for improving staff
Rate.
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention can be tied mutually
It closes.
More than, only specific embodiment of the present utility model, but protection scope of the utility model is not limited thereto,
Anyone skilled in the art within the technical scope disclosed by the utility model, the variation that can readily occur in or replaces
It changes, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with claim
