Abstract
The utility model relates to a chemical feeding device for a heat supply circulating system. The chemical feeding device for the heat supply circulating system is characterized by comprising a chemical box and a chemical liquid box, wherein a chemical feeding pipe is arranged between the chemical box and the chemical liquid box, a chemical feeding valve is installed on the chemical feeding pipe, the chemical liquid box is connected to the heat supply circulating system in parallel through a liquid inlet pipe and a liquid outlet pipe, the liquid inlet pipe is arranged on the upper portion of the chemical liquid box, the liquid outlet pipe is arranged at the bottom of the chemical liquid box, and the liquid inlet pipe and the liquid outlet pipe are respectively provided with a control valve. Due to the facts that the structure of the chemical feeding device for the heat supply circulating system is not limited by the height of a large-sized water tank, and the chemical feeding device only needs to be connected to the heat supply circulating system in parallel, operability is improved, labor intensity of management personnel is reduced, corrosion of the water tank is avoided, the frequency of cleaning the water tank is reduced, and maintenance cost is reduced; in addition, the chemical feeding device for the heat supply circulating system has the advantages of being simple in structure, reasonable in design and capable of being easily connected with an existing heat supply circulating system.
Description
Technical field
The utility model belongs to heating system water circulation water quality adjustment technical field, particularly relates to a kind of for the heat circulating system chemicals dosing plant.
Background technology
Much in the heat exchange station of heat unit, needing to add some stink agent, prevent that the user from stealing water at present, but in standing, be all that the stink agent directly is added in water tank and is squeezed in system by small pump, going down for a long time water tank can be by heavy corrosion, or heavy base impurity causes water tank normally to use, and general our stand water tank volume larger maintenance difficult all of interior use, renewal cost is very high, if leak and will stop heat supply like this impact is very large at heating period water tank seriously corroded, also have the height of water tank very high, also very dangerous in actual dosing.Like this
Summary of the invention
The utility model provides a kind of water tank of having protected simple in structure, easy to install, effective for solving the technical problem existed in known technology, increase work efficiency for the heat circulating system chemicals dosing plant.
The technical scheme that the utility model is taked for the technical problem existed in the solution known technology is:
A kind of for the heat circulating system chemicals dosing plant, it is characterized in that: comprise medicine box, spray tank, be provided with chemical feed pipe between described medicine box and spray tank, the dosing valve is installed on described chemical feed pipe, described spray tank is connected in parallel in heating system by feed tube and drain pipe, described feed tube is positioned at the top of spray tank, and described drain pipe is positioned at the bottom of spray tank, and by-pass valve control all is installed on feed tube and drain pipe.
The utility model can also adopt following technical measures:
The sidewall of described spray tank also is provided with several the parallel branches of controlling spray tank inner liquid medicine height, and every parallel branch is provided with by-pass valve control.
Advantage and the good effect that the utlity model has are: because the utility model adopts above-mentioned technical side, this chemicals dosing plant in parallel in existing confession heat circulating system, not limit by the height of bulky water tank on the one hand, improved operability, reduce administrative staff's labour intensity, the colleague also avoids the corrosion to water tank, has reduced the cycle of water tank cleaning, has reduced maintenance cost; The utility model also has simple in structurely, reasonable in design in addition, is easy to be connected with existing heating system.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is used state diagram.
In figure: 1, medicine box; 2, spray tank; 3, chemical feed pipe; 4, dosing valve; 5, feed tube; 6, drain pipe; 7, by-pass valve control; 8, by-pass valve control; 9, by-pass valve control; 10, by-pass valve control; 11, by-pass valve control.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of for the heat circulating system chemicals dosing plant, comprise medicine box 1, spray tank 2, be provided with chemical feed pipe 3 between described medicine box and spray tank, dosing valve 4 is installed on described chemical feed pipe, and described spray tank is connected in parallel in heating system by feed tube 5 and drain pipe 6, and described feed tube 5 is positioned at the top of spray tank, described drain pipe is positioned at the bottom of spray tank, and by-pass valve control (7,8) all is installed on feed tube 5 and drain pipe 6.
The sidewall of described spray tank also is provided with several the parallel branches of controlling spray tank inner liquid medicine height, every parallel branch is provided with by-pass valve control, adopt three parallel branches in this enforcement, the control valve on every parallel branch under be respectively by-pass valve control 9, by-pass valve control 10 and by-pass valve control 11.
In said structure, when dosing, closing control valve (7, 8, 9, 10, 11) open dosing valve 1 when continuous full medicament, close the dosing valve and open by-pass valve control 7 and by-pass valve control for No. 1 No. 8, so owing to having pressure and the flow direction medicament can be along with being circulated in the water (flow) direction flowed into system in pipeline, now in spray tank, be full of water when carrying out dosing next time again, closing control valve 7 and by-pass valve control 8, open by-pass valve control (9 according to the chemical feeding quantity different choice, 10, 11), water in spray tank is emitted, emit rear closing control valve (9, 10, 11) open again No. 1 and carry out dosing.
The above is only to preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
