Abstract
The utility model relates to a kind of energy-conservation twin flue water supply flow metering system, this system comprises main water supply pipe, front end valve, flow meter and the rear end valve be successively set on along water (flow) direction on main water supply pipe, described system also comprises the by-pass line in parallel with main water supply pipe, bypass front end valve, bypass flow meter and the bypass rear end valve be successively set on along water (flow) direction on by-pass line, and the forward and backward two ends of described by-pass line are connected with main water supply pipe respectively by front end adapter and rear end adapter.Compared with prior art, the utility model structure is simple, bypass line road in parallel on main water supply pipe, flow when can detect that summer, hot water output was less by bypass flow meter, can realize the winter, season in summer two water supply line switching, and the precision that when can ensure winter, Xia Liangji, hot water flow detects, economical and practical, can effectively increase flow measurement accuracy.
Description
Technical field
The utility model relates to a kind of metering system, especially relates to a kind of energy-conservation twin flue water supply flow metering system.
Background technology
At present, the flow measurement of hot and cold water is that the mode installing flow meter additional by pipeline realizes.But because the hot and cold water consumption of terminal temperature difference can change with season, winter is hot water demand when measuring maximum, now, bore is that the flow meter of DN400 can the flow of accurate-metering about 400t/h; But, when summer, workshop is fewer for the demand of hot water, flow probably at about 100t/h, now, then can there is the unmeasurable situation of low discharge in the flow meter re-using DN400, thus make metering not accurate enough, be unfavorable for the promptness ensureing hot water supply, but also hot water can be caused to waste, increase running cost, remain to be further improved.
Summary of the invention
The purpose of this utility model is exactly provide a kind of structure simple to overcome defect that above-mentioned prior art exists, economical and practical, effectively can increase the energy-conservation twin flue water supply flow metering system of flow measurement accuracy.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of energy-conservation twin flue water supply flow metering system, this system comprises main water supply pipe, front end valve, flow meter and the rear end valve be successively set on along water (flow) direction on main water supply pipe, described system also comprises the by-pass line in parallel with main water supply pipe, bypass front end valve, bypass flow meter and the bypass rear end valve be successively set on along water (flow) direction on by-pass line, and the forward and backward two ends of described by-pass line are connected with main water supply pipe respectively by front end adapter and rear end adapter.
Described front end valve, flow meter and rear end valve are successively set between front end adapter and rear end adapter.
Described main water supply pipe is DN400 pipeline, and described flow counts DN400 flow meter.
Described main water supply pipe is also provided with total valve, and described front end adapter is arranged between total valve and front end valve.
The caliber of described by-pass line is less than the caliber of main water supply pipe.
Described by-pass line is DN200 pipeline, and described bypass flow counts DN200 flow meter.
In actual use, during winter, because workshop hot water demand is larger, now, open total valve, front end valve, rear end valve, and close bypass front end valve, bypass rear end valve, hot water, by main water supply pipe, flows through flow meter, by cmf record flow now; When summer, because workshop hot water demand is less, now, open total valve, bypass front end valve, bypass rear end valve, and closed front end valve, rear end valve, hot water enters by-pass line by front end adapter, flow through bypass flow meter, and by bypass flow meter record flow now.
Compared with prior art, the utility model adopts bypass line road in parallel on main water supply pipe, because the caliber of by-pass line is less than main water supply pipe, flow when can detect that summer, hot water output was less by bypass flow meter, can realize the winter, season in summer two water supply line switching, and the precision that when can ensure winter, Xia Liangji, hot water flow detects, the promptness that hot water is supplied can be ensured, and reduce unnecessary hot water waste, solve original water supply line water supply flow and measure inaccurate problem.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment:
A kind of energy-conservation twin flue water supply flow metering system, this system comprises main water supply pipe 1, the front end valve 3 be successively set on along water (flow) direction on main water supply pipe 1, flow meter 4 and rear end valve 5, system also comprises the by-pass line 2 in parallel with main water supply pipe 1, the bypass front end valve 6 be successively set on along water (flow) direction on by-pass line 2, bypass flow meter 7 and bypass rear end valve 8, and the forward and backward two ends of by-pass line 2 are connected with main water supply pipe 1 respectively by front end adapter 9 and rear end adapter 10.
Wherein, front end valve 3, flow meter 4 and rear end valve 5 are successively set between front end adapter 9 and rear end adapter 10.Main water supply pipe 1 is also provided with total valve 11, and front end adapter 9 is arranged between total valve 11 and front end valve 3.The caliber of by-pass line 2 is less than the caliber of main water supply pipe 1.
In the present embodiment, main water supply pipe 1 is DN400 pipeline, and flow meter 4 is DN400 flow meter.By-pass line 2 is DN200 pipeline, and bypass flow meter 7 is DN200 flow meter.
In actual use, during winter, because workshop hot water demand is larger, now, open total valve 11, front end valve 3, rear end valve 5, and close bypass front end valve 6, bypass rear end valve 7, hot water by main water supply pipe 1, flows through flow meter 4, records flow now by flow meter 4; When summer, because workshop hot water demand is less, now, open total valve 11, bypass front end valve 6, bypass rear end valve 8, and closed front end valve 3, rear end valve 5, hot water enters by-pass line 2 by front end adapter 9, flows through bypass flow meter 7, and records flow now by bypass flow meter 7.
