Abstract
The utility model discloses automatic regulation and control equipment of a boiler damper, which belongs to the field of automatic regulation and control equipment. The equipment is composed of a control module, a data recording module and a motor, wherein the control module, the data recording module and a valve detection and switch module are connected to a central terminal; the output of the control module is connected with a display screen; the data recording module is mutually connected with the motor; and the output of the motor is connected with the damper. According to the automatic regulation and control equipment of the boiler damper, a P+F guard grating is provided with a special configuration software which is more simple and convenient than a position transmitting module during configuration; no fault occurs; maintenance is reduced; position feedback of the damper no longer affects the work of an operator; and steam supply is ensured.
Description
Technical field
The utility model belongs to device for automatically regulating, relates to a kind of boiler air door device for automatically regulating specifically.
Background technology
Boiler air door device for automatically regulating is power with the AC power, accepts unified standard signal 4-20mA signal, through DCS system control relay; The output Switching Power Supply; Drive motors advanced mechanical reduction, converted corresponding output shaft corner displacement to; Handle the air door baffle plate, realize the control and regulation of air quantity.Position transmitter in original air door is the 4-20mA current signal that the angular displacement of axle is converted to direct current; Because it is very high that the module failure rate is sent out in the WF-S type position in the former loop; Often break down because module is sent out in the position, operating personnel can't see the aperture of air door, influence the aperture of air door; Influence the normal operation of boiler, can have influence on the steam supply of whole factory when serious.
Summary of the invention
In order to address the above problem, the utility model is intended to create a kind of boiler air door device for automatically regulating of simple to operate, stable and safe in operation.
The boiler air door device for automatically regulating of the utility model is made up of control module, data recordin module and motor, and control module, data recordin module and valve detection modular converter are connected in center terminal; Control module output connects display screen, and data recordin module and motor are coupled to each other, and motor connects with air door.
As the further improvement of the utility model, air door is a venetian blind type.
The boiler air door device for automatically regulating of the utility model, reasonable in design, because the P+F guard grating has special configuration software, it is easy to be a lot of to send out module than the position during configuration; Fault-free has reduced maintenance, and operating personnel can be again because the position feedback of air door influence operation guaranteed the supply of steam yet.
Description of drawings
Fig. 1 is the boiler air door device for automatically regulating structured flowchart of the utility model;
Fig. 2 is the control principle figure of the utility model.
The specific embodiment
The boiler air door device for automatically regulating of the utility model is to be made up of control module, data recordin module and motor, and described control module, data recordin module and valve detection modular converter are connected in center terminal; Control module output connects display screen, and data recordin module and motor are coupled to each other, and motor connects with air door.
Described air door is a venetian blind type.
The boiler air door device for automatically regulating of the utility model, the terminal 5 in control room changes 24VDC+ into by original 220VAC+, and is as shown in Figure 2; Receive the terminal 7 of intermediate connection case, pick out 12 terminals that a cable is received the intermediate connection case by the terminal 3 in control room, as 24VDC-; 7 of intermediate connection case; 12 terminals are received 14,15 terminals of P+F guard grating, as its power supply; The terminal 1 (zero line) in control room is constant, receives the terminal 6 of intermediate connection case, is received the terminal 3 of motor again by terminal 13, as the zero line of motor; 2,4th of control room, relay contact is received 3 and 8 terminals of intermediate connection case, is received 1,2 terminal of motor again by 5,10 terminals, controls the just commentaries on classics of motor, counter-rotating through the control live wire.18,19,20 terminals of potentiometer are received 18,19 of intermediate connection case; 20 terminals, 1,2,3 terminals of receiving the P+F guard grating again receive the resistance signal of potentiometer; By 7, the 8 terminals output 4-20mA analog signal of guard grating, deliver to 1,2 terminal of intermediate connection case again; Deliver to 6,7 terminals in control room again, indicate to DCS.Its principle is: the output of control relay from the control room, and control rotating and reverse of on-the-spot motor, thereby reach the purpose of control air door, control the size of air quantity.The angular displacement that air door produces converts corresponding resistance value to and delivers to the P+F guard grating; The P+F guard grating converts resistance value to corresponding 4-20mA signal; The DCS system that delivers to the control room shows; At this moment operating personnel can see the aperture of air door, and operating personnel can further come the output of regulating relay according to the aperture of air door, control the aperture of air door.
Claims (2)
1. boiler air door device for automatically regulating is to be made up of control module, data recordin module and motor, it is characterized in that control module, data recordin module and valve detection modular converter are connected in center terminal; Control module output connects display screen, and data recordin module and motor are coupled to each other, and motor connects with air door.
2. boiler air door device for automatically regulating as claimed in claim 1 is characterized in that air door is a venetian blind type.
