Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Fig. 1 to Fig. 3 shows the embodiment of core of integrative calorimeter of the present invention.Comprise the water inlet pipe 5 and return pipe 4 of device in table body 10; The rear end of water inlet pipe 5 connects a flow of inlet water sensor 6, and the front end of return pipe 4 connects a circling water flow rate sensor 3; As shown in Figure 1.Flow sensor is to promote wheel rotation by current in the pipeline, utilizes electromagnetic induction principle to produce umber of pulse, converts corresponding flow again to, is converted into heat.Adopt flow of inlet water sensor 6 and circling water flow rate sensor 3 and usefulness, can play the effect of balance metering, can overcome many shortcomings of single-sensor calorimeter.For example forbid that the user illegally uses the backwater in the heat supplying pipeline etc.
The front end that is positioned at flow of inlet water sensor 6 in water inlet pipe 5 is provided with a screen pack 9, and the filtering surface of screen pack 9 is set to and water inlet pipe 5 axes intersect 45 degree pitch angle, as shown in Figure 1; To improve its filtration efficiency.The conventional filtration mesh-shaped is circular, filtering surface is perpendicular to the pipeline axis, and the plane of 45 ° of oblique angle screen packs and pipeline axis angle at 45, and the filter screen ovalize, useful area is bigger than circle in same pipeline, the also corresponding increase of mesh, fluid resistance is little, impurity is not easy to be flushed to return pipe by electronic flushing valve again attached on the filter screen, prevents the impurity blocking pipeline.
The front end of screen pack 9 is provided with an inflow temperature sensor 7 that is used to control and monitor inflow temperature; As shown in Figure 1, 2.
The front end of screen pack 9 is provided with an automatically controlled water intaking valve 11 that is used to control water inlet switch.The front end of automatically controlled water intaking valve 11 is provided with the hot water access port 51 that is used to enter user's heating installation 13.
One end of return pipe 4 is provided with the return pipe interface 41 that is used to connect 8 drainage waters of user's heating installation; The front end of return pipe interface 41 is provided with one year ends valve 1, carries the function of ending valve 1 and be to be used to stop that the user is lack of standardization discharges water i.e. only a few user's the water behavior of stealing; If the user takes illegal lack of standardization discharging water from the return pipe of heating pipeline, cause enormous economic loss can for heating system and heating unit, be difficult to correctly measure the heat energy of actual consumption again.
The front end that carry to end valve 1 is provided with an electrical ball valve 2, the function of electrical ball valve 2 be used for automatically, the impurity of periodic flushing screen pack and valve; The stifled effect that can influence user's heating of impurity resistance in screen pack and valve and its pipeline.
The front end of electrical ball valve 2 is provided with a circling water flow rate sensor 3.The front end of circling water flow rate sensor 3 is connected with water return pipeline.
The connector 8 that middle part between water inlet pipe 5 and the return pipe 4 is provided with the band inner chamber is like this designs: a connecting hole 83 is set in the upper end of return pipe 4, the lower end of water inlet pipe 5 a joint pin 51 is set, joint pin 51 surfaces are provided with " U " word buckle 81; Connecting hole 83 matches with joint pin 51 and " U " word buckle 81 thereof; As shown in Figure 3.
Be provided with end-face seal ring 82 between the end face of connecting hole 83 and joint pin 51, to prevent the seepage that is connected end face between water inlet pipe and the return pipe.
Adopt new-type U type bayonet socket to be tightly connected between water inlet pipe 5 and the return pipe 4, go up the lower pipeline position to not just when avoiding connecting, cause installation inconvenience and sealing property bad with thread seal.The advantage that U type bayonet socket is tightly connected is a good seal performance, and is easy for installation, and last lower pipeline position can arbitrarily angledly be adjusted.
