Abstract
The utility model relates to a high-accuracy non-magnetic sensitive intelligent water meter, which comprises a meter shell, a valve seat, a machine core, an electric valve, a jet stream generator and a non-magnetic sensor. The utility model improves the structure of a traditional multi-jet dry water meter, the jet stream generator is additionally arranged, a non-magnetic sensitive signal collecting device is utilized, the starting flow of the water meter is reduced, and thus measurement is reasonable and accurate. Illegal water use is avoided, and the aim of saving water is obtained. The utility model has the advantages of reasonable and novel structure and compact and beautiful appearance.
Description
The utility model relates to a kind of high precision does not have magnetic sensing intellectual water meter, is the high precision water meter of the accurate metering of low discharge specifically.
Traditional multithread bundle velocity type water meter, water directly enters movement after the watchcase water inlet flows into, the drive impeller rotation, the rotation of impeller is connected with the input end of mechanical counter of water meter by the magnet steel transmission, existing intellectual water meter major part is to set up magnet on certain one-level of the mechanical count of original water gauge---the such magnetic of the tongue tube pass of spreading, realize the collection of count signal.These structures and signals collecting mode, energy loss is big in Machine Movement Process, causes metering inaccurate; On the other hand, adding magnet---tongue tube can cause certain resistance to mechanical part, has further increased the initiating flow of water meter; Three, the initiating flow of this multithread Shu Shuibiao itself is just bigger, makes that stealing the water behavior succeeds.
The utility model purpose is: by the improvement to water meter physical construction, adopt no magnetic transducing signal harvester, realize the accurate measurement of low discharge, thereby realize improving the precision and the antimagnetic steal of water meter.
The technical scheme that the utility model is implemented is: comprise compositions such as watchcase, valve seat, movement, jet baffle plate, wedge action valve, Based Intelligent Control plate, non-magnetic sensor.Dress valve seat (2) in the watchcase (1), valve seat (2) are gone up and jet plate washer (3) are installed, jet baffle plate (3) and spring (4) butt.Aperture on the valve seat (2) is connected with jet tubule (5), jet tubule (5) is connected with movement (6), movement (6) is installed on the valve seat (2), non-magnetic sensor (7) is contained in the top center of movement, battery (8) is connected with primary control program plate (9), and primary control program plate (9) is connected with motor gearbox (10), and motor gearbox (10) is connected with nut (11), nut (11) is socketed on the screw rod (12), and screw rod (12) is connected with valve (13).Directly by being installed in the watchcase, movement is contained on the valve seat valve seat, and semicircle sheet metal is housed on the movement impeller, and the Sensor section of non-magnetic sensor is close to above the sheet metal, between separate by the dividing plate of movement, realize the sealing in table chamber.The valve seat of the inlet end of water meter is provided with jet baffle plate and ostium excurrens, when water consumption is very little, the jet baffle plate is blocked water inlet, current can only enter movement via tubule by ostium excurrens, because sectional area reduces, hydraulic pressure increases, form jet, the rotation of promotion impeller realizes the accurate measurement of low discharge, reduces the initiating flow of water meter.When wheel rotation, the metal halfround bar slice moves in a circle, and by sensor water-flow signal is transformed into electric signal output, than the magnetic transmission, impeller is subjected to resistance and reduces greatly, and the initiating flow is further reduced.At the water meter water outlet end, valve seat is provided with a wedge action valve, and gate valve is connected with an electric gear roller box, comes the control gear case to reach the open and close of valve by the primary control program plate.
The utility model novel and reasonable structure, outward appearance is small and exquisite, and measuring accuracy height, control are the leading-edge products of modern domestic water meter reliably, have fabulous market outlook.
The utility model is described in further detail now to lift an example.
Fig. 1, structural front view of the present utility model.
As shown in Figure 1, dress valve seat (2) in the watchcase (1), valve seat (2) are gone up and jet plate washer (3) are installed, jet baffle plate (3) and spring (4) butt.Aperture on the valve seat (2) is connected with jet tubule (5), jet tubule (5) is connected with movement (6), movement (6) is installed on the valve seat (2), non-magnetic sensor (7) is contained in the top center of movement, battery (8) is connected with primary control program plate (9), and primary control program plate (9) is connected with motor gearbox (10), and motor gearbox (10) is connected with nut (11), nut (11) is socketed on the screw rod (12), and screw rod (12) is connected with valve (13).
This table course of work is as follows: the user is after sell water station and buy water, in the water information of the purchasing input table in the card, after primary control program plate (9) receives and purchases water information, send out the valve instruction, motor gearbox (10) action, drive nut (11) rotation, the screw rod that is attached thereto (12) rises thereupon, opens the aperture on the valve earlier, then spurs valve (13) and rises, open valve, water meter is opened the valve water.
During water meter downstream water, fluid enters from the import of watchcase (1), if the tail water flow is very little, jet plate washer (3) is withstood by spring (4), block water inlet, the tiny jet impulse impeller that current can only form via jet tubule (5) by the aperture that is located on the valve seat (2), make the impeller rotation in the movement (6), make water meter under low discharge, realize metering, when the downstream water consumption was big, the pressure reduction on jet baffle plate (3) both sides was big, thus the pressure compression spring (4) of Xing Chenging, the jet baffle plate is open, and water meter enters normal operating condition.
On the impeller of water meter movement (6) semicircle sheet metal is housed, in impeller when rotation,, sheet metal rotates thereupon, is close to the rotation that the non-magnetic sensor (7) of movement (6) is sensed impeller, rotating signal is transformed into electric signal sends to primary control program plate (9), realize counting.
When user's the purchase water yield ran out, the primary control program plate sent the pass valve and instructs to motor gearbox (10), motor gearbox (10) work, by nut (11) and the screw rod (12) that is attached thereto, drive valve (13) and descend, block the apopore on the valve seat (2), realize closing the valve control of cutting off the water supply.
