Abstract

The utility model relates to a hot water boiler temperature control system. The hot water boiler temperature control system comprises a hot water boiler (1), a main water supply pipe (2), a main water return pipe (3), a water supply circulating pump (4) and a temperature controller (5), a distribution pipe (7) is connected between a water outlet and a water return port of the hot water boiler, a proportioning valve (8) is mounted on the distribution pipe (7), a PID (proportion, integration and differentiation) input interface of the temperature controller is connected with a temperature sensor (6), and a control interface of the temperature controller is connected with an actuator on the proportioning valve (8). The hot water boiler temperature control system is used for tobacco nursery pond circulation heating temperature regulating and control devices, and is capable of achieving simple structure and low equipment cost and improving heat efficiency of a pressureless boiler hot water heating system.

Description

The temperature-controlling system of hot-water boiler
Technical field
The utility model relates to tobacco seedling pond circulation heating adjustment control device; Be specifically related to a kind of temperature-controlling system of hot-water boiler.
Background technology
The growing environment that prior art will provide a kind of suitable cigarette seedling to grow up strong and sturdy needs in the tobacco seedling system.Generally be to increase the pressure-less boiler hot-water heating system; In order to make tobacco seedling pond circulation heating temperature stabilization, must increase a constant temperature water tank at the pressure-less boiler output end of hot water, make up a cycle heat exchange loop at constant temperature water tank and pressure-less boiler, and adopt variable frequency pump to cooperate temperature controller to realize that heat supply temperature is stable.So just cause equipment cost to increase, simultaneously more cycle heat exchange loops also can make system thermal efficiency low.
The utility model content
Technical problem to be solved in the utility model is: overcome above-mentioned deficiency, a kind of temperature-controlling system of hot-water boiler is provided.Can implementation structure simple, equipment cost be low, can improve the thermal efficiency of pressure-less boiler hot-water heating system simultaneously.
The technical solution of the utility model is: a kind of temperature-controlling system of hot-water boiler comprises hot-water boiler, main-supply, main water return tube, supplies water-circulating pump and temperature controller; The hot-water boiler delivery port is by connecting main-supply for water-circulating pump, and the hot-water boiler water return outlet connects main water return tube; Establish temperature sensor on the main-supply, between hot-water boiler delivery port and water return outlet, connect an isocon, a ratio adjusting valve is installed on this isocon; The PID input interface of temperature controller connects temperature sensor, and the control interface of temperature controller links to each other with actuator on the ratio adjusting valve.
Temperature display and height temperature alarm device are arranged on the said temperature controller.
Compared with the prior art, the utility model has the advantages that: omitted constant temperature water tank and variable frequency pump cycle heat exchange loop; Only connect an isocon between hot-water boiler delivery port and water return outlet, the proportion of utilization control valve just can be realized temperature control.Have simple in structurely, equipment cost is low, the characteristics that the thermal efficiency of heating system is high.The control of the utility model passing ratio valve finally reaches tobacco seedling pond temperature stabilization at 35 ℃; Build the grow up strong and sturdy growing environment of needs of a kind of suitable tobacco floating seed rearing seedling.
Description of drawings
Fig. 1 is system architecture schematic diagram of the present utility model.
Reference numeral is: 1 hot-water boiler; 2 main-supplies; 3 main water return tubes; 4 for water-circulating pump; 5 temperature controllers; 6 temperature sensors; 7 isocons; 8 ratio adjusting valves.
The specific embodiment
Describe the utility model below in conjunction with accompanying drawing in detail with the specific embodiment.
A kind of temperature-controlling system of hot-water boiler comprises hot-water boiler 1, main-supply 2, main water return tube 3, supplies water-circulating pump 4 and temperature controller 5; The hot-water boiler delivery port is by connecting main-supply 2 for water-circulating pump 4, and the hot-water boiler water return outlet connects main water return tube 3; It is characterized in that: establish temperature sensor 6 on the above-mentioned main-supply 2, between hot-water boiler delivery port and water return outlet, connect an isocon 7, a ratio adjusting valve 8 is installed on this isocon 7; The PID input interface of temperature controller connects temperature sensor 6, and the control interface of temperature controller links to each other with actuator on the ratio adjusting valve 8.

Claims (2)
