Further, it is provided with the signal transmitter being made up of signalling component magnet steel and tongue tube or magnetic switch in described sender base table, and is sent water measurement signal by tongue tube or magnetic switch to described governor circuit.
Further, described governor circuit includes single-chip microcomputer and the power module being connected with single-chip microcomputer, low voltage detecting module, pulse measurement module, IC-card module for reading and writing, LCD MODULE, switch valve control module, data storage, reset switch, acoustic-optic alarm, wherein, pulse measurement module is for receiving the water measurement signal that described sender base table sends, switch valve control module is for controlling opening or closing of switch valve, when switch valve cuts out because the single reaching to set continues water-supply quantity or the lasting water supply time of single, warned by sound and light alarm, and resetted by reset switch, IC-card module for reading and writing is used for writing the forward purchasing water yield, LCD MODULE is while display water-meter essential information, it is additionally operable to show that set single continues water-supply quantity or single continues water supply time.
Further, in described sender base table, it is provided with ultrasound wave water measurement sensor, this ultrasound wave water measurement sensor sends water measurement signal to described governor circuit.
Further, described switch valve is ball valve, motor drive and open or close, and described governor circuit controls the work of described motor.
This utility model water meter continues water supply time limit by single continues water-supply quantity or single, make in the case of leaking occurs in water meter downstream pipe, to leaking the water yield or the persistent period of leaking limits, thus can reduce and even avoid the destruction to causing with water place of leaking.
Accompanying drawing explanation
Fig. 1 is this utility model water meter principle assumption diagram；
Fig. 2 is governor circuit principle assumption diagram in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is illustrated.
Fig. 1 is the preferred embodiment of this utility model water meter.As shown in FIG., this water meter includes that sender base table, switch valve, governor circuit, sender base table and switch valve are arranged on the water stream channel between water meter water inlet and outlet, and switch valve is ball valve, motor drive and open or close.
Being provided with the signal transmitter being made up of signalling component magnet steel and tongue tube or magnetic switch in sender base table, the form that arranges of signal transmitter refers to Chinese patent ZL94245635.1.When having current out-of-date in sender base table, tongue tube or magnetic switch send water measurement pulse signal to governor circuit.
Fig. 2 is governor circuit principle assumption diagram.The water measurement pulse signal that sender base table sends is received by the pulse measurement module of governor circuit, and single-chip microcomputer is shown by LCD MODULE after water measurement pulse signal is processed into water-supply quantity.
Being provided with IC-card module for reading and writing in governor circuit, user is by the IC-card module for reading and writing write forward purchasing water yield, and when water-supply quantity reaches to purchase in advance the water yield, single-chip microcomputer i.e. drives motor closing switch valve by switch valve control module.After user writes the forward purchasing water yield again, switch valve is opened, and water meter enters new metering cycle.
In addition to conventional water meter function, the water yield that single is persistently supplied water by governor circuit is also carried out setting, when the water yield that single persistently supplies water reaches to set numerical value, and governor circuit closing switch valve.Being provided with reset switch on governor circuit, after switch valve cuts out because single water-supply quantity reaches to set numerical value, user need to open switch valve by reset switch.
In addition to single being continued water-supply quantity and is set, it is also possible to by governor circuit, single is continued water supply time and be set, when the lasting water supply time of single reaches to set numerical value, governor circuit i.e. closing switch valve.
It is set, as long as one of them reaches to set numerical value, governor circuit i.e. closing switch valve in the two it is, of course, also possible to continue water supply time by governor circuit water-supply quantity lasting to single and single simultaneously.
In routine use, likely there is the leakage that flow is less in the pipeline in water meter downstream, because the flow that leaks is little, people are difficult to find at the beginning, but once find, indoor article, furniture are soaked the most for a long time, and form greater loss.Single is continued water supply time be set, can effectively reduce relatively low discharge and leak caused harm.
Additionally, its forward purchasing water yield is reached because the closedown of switch valve is likely to be user's water consumption, it could also be possible that because the lasting water-supply quantity of single or the lasting water supply time of single reach setting value and close, thus acoustic-optic alarm can be set on governor circuit, the situation that switch valve reaches setting value because of the lasting water-supply quantity of single or the lasting water supply time of single and cuts out warns, to inform the reason that subscriber switch valve cuts out, it is user-friendly to.
Liquid crystal indicator in governor circuit both can be the LCDs being set directly on main control board, it is also possible to be the LCDs of teletransmission, and teletransmission mode both can be wired, it would however also be possible to employ wireless.
Signal transmitter in above-described embodiment sender base table be all multi-form in one, as water measurement device, can use the water measurement sensor of various suitable pattern as signal transmitter, such as ultrasound wave water measurement sensor.
It addition, above-mentioned switch valve is made up of ball valve, this ball valve is arranged on the water stream channel between intake-outlet, is directly closed water stream channel by ball valve.In addition, it is also possible to switch valve is carried out control bound work as pilot valve.And, switch valve can use the valve of various suitable pattern, and is not limited to ball valve.
It is understood that above-described embodiment is merely to illustrate that principle of the present utility model and the illustrative embodiments that uses, this utility model is not limited thereto.For those skilled in the art, in the case of without departing from principle of the present utility model and essence, can make various modification and improvement, these modification and improvement are also considered as protection domain of the present utility model.
