Description
Technical field
The utility model relates to a kind of water meter, is meant a kind of water meter that the anti-pressure surge of anti-backflow is disturbed that has especially.
Background technology
At present, existing water meter principle of work is: current enter water meter impact impeller from the water inlet of water meter, and wheel rotation also passes to counter, by counter records user water consumption.Under the prerequisite of correctly installing and using, water meter can play the effect of accurate metering, still, if the user uses the water meter upside-down mounting, under the impact of current, impeller will reverse, and drive numeration of counter, the water yield that water meter shows reduces, and causes metering wrong, thereby reaches the purpose of stolen water; And present high-rise user uses water tower and water pot to guarantee that the phenomenon of secondary water-supplies such as water supply is more and more, and this causes user pipe aqueous reflux phenomenon through regular meeting, causes to cause the water meter measurement error.Moreover the pressure of water supply pipe often fluctuates, and this reason is that pipeline hydraulic pressure itself is just unstable, and Another reason is the proximal subscribers water, causes other user pipe water pressure fluctuations.Under this pressure surge, the water meter in the useless water state can produce the phenomenon of rotation because of inertia effect, causes the water meter measurement error, causes the dispute between user and water supply company, and this also is a big drawback of existing water meter.
For this reason, at in November, 1999 Granted publication, Granted publication number is: CN2350734Y, the patent No. is: 98223749.9, name is called in the utility model of " the unidirectional tap water meter that has non-return valve " and discloses a kind of water meter, its principal character includes housing, be arranged on the water meter turbine sum counter of enclosure interior and advance, water delivering orifice, in water inlet, be provided with an one way stop peturn valve, it can effectively prevent to be inverted and water meter is installed is carried out stolen water, only locate but still have some deficits, be not provided with resetting-mechanism owing to end the valve plug of valve for unidirectional time, make water meter under normal operating condition, end valve unidirectional time and no matter be in normally open when water meter is opened or closed always, sealing is compact inadequately, just be difficult to solve owing to flowing water pressure fluctuation in the pipeline, the error of the water meter measurement that causes.
Summary of the invention
The utility model is in order to solve the weak point that above-mentioned prior art exists, a kind of simple in structure, sealing compactness, easy to use is provided, even if the user is inverted the purpose that can not reach stolen water is installed, can also effectively prevents the water meter that the water flow pressure fluctuation is disturbed in addition.
For achieving the above object, the utility model adopts following scheme: water meter is disturbed in the anti-pressure surge of a kind of anti-backflow, include housing, be arranged on the water meter turbine sum counter of enclosure interior and advance, water delivering orifice, in water inlet or water delivering orifice, be sealed and installed with the anti-pressure surge interference unit of an anti-backflow, the anti-pressure surge interference unit of anti-backflow includes sleeve pipe, major axis, seal pad and back-moving spring, its middle sleeve is fixedly connected on the inner chamber of water inlet or water delivering orifice, be provided with intake antrum in the sleeve pipe, one end of major axis is fixedly connected on the sleeve pipe, seal pad is actively socketed on the major axis with back-moving spring, and seal pad cooperates with the end face motive seal of sleeve pipe water side by back-moving spring.
The utility model further is set to: described major axis one end is installed in the mount pad of sleeve pipe, and mount pad is fixedly connected on center in the sleeve pipe by reinforcement, forms intake antrum between each reinforcement.
Described seal pad is between sleeve pipe and back-moving spring, and major axis is provided with the setting nut of back-moving spring, and setting nut is connected with the major axis threaded engagement.
Be provided with safety washer between described back-moving spring and the setting nut.
The beneficial effects of the utility model are: the utility model compared with prior art, because water inlet or water delivering orifice at water meter are equipped with the anti-pressure surge interference unit of anti-backflow, integrating metering, antitheft, anti-backflow, anti-pressure surge disturbs, when correctly installing and using, can play the purpose of accurate water measurement; When the water meter upside-down mounting, can stop automatically supplying water, stopped to utilize the water meter upside-down mounting to come the phenomenon of stolen water; Moreover, the anti-pressure surge interference unit of anti-backflow is provided with back-moving spring, make seal pad closely outlet of closed casing the time without water state, the water meter rotation phenomenon that can effectively stop the pipeline water pressure fluctuations to cause, overcome and now caused the wrong defective of metering because of water pressure fluctuations with water meter, thereby saved water resource, had good economic benefit and social benefit.
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
