Description
(1), technical field
The utility model relates to a kind of water meter, is a kind of high-precision measuring water meter concretely.
(2), background technology
The principle of work of existing tap water gauging table is, tap water flows in the housing from water inlet, flow through and drive shell in the impeller rotation, flow out from water delivering orifice then.Gear counter work on the described impeller impeller box shows discharge.
Therefore, following two major defects of existing tap water gauging table ubiquity: the first, the water supply line water pressure fluctuations can cause the water meter rotation phenomenon, and water meter also might be rotated further after promptly water swivel was closed.The second, the initiating flow is too high, can not measure water clock water.Because measuring the metering of existing water meter and actual used water, the existence of these two kinds of shortcomings showed very big error.
(3), utility model content
The purpose of this utility model is the deficiency that overcomes above-mentioned existing tap water gauging table, and a kind of high precision water meter is provided, and mainly solves following two technical matterss by improving structure: the first, the water meter rotation problem that causes of water supply line water pressure fluctuations.The second, the problem that can not measure water clock water.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of high precision water meter, it comprises the housing that has water inlet and water delivering orifice, and the impeller box that impeller is housed is installed in housing, it is characterized in that: the be threaded valve cover of outer end band freeing port of described water outlet end; Be provided with the CT valve between water delivering orifice and freeing port, the shutoff face of CT valve cooperates with the outer face of water delivering orifice, and the valve rod of CT valve can be installed on the support axially slidably; Have crossed strip on the valve rod of CT valve, be fixed with in the shutoff face of CT valve and the outer face of water delivering orifice the contact pin that can be deep into the impeller clearance of impeller when closed on the shutoff face of CT valve.
Offer groove on the shutoff face of CT valve, this end face of establishing groove is provided with glued membrane, and the tail end of described contact pin is fixed on the glued membrane.
Establish the 3rd rubber cushion between support and the housing.
The bottom of impeller box is provided with the impeller-driven chamber of lower end band screen pack in housing; Indoor being provided with the impeller-driven chamber of impeller-driven is the valve body positioning seat of one, and AT valve and BT valve are installed on the valve body positioning seat; Have longitudinal spring on the valve rod of BT valve; Two chambers about space between impeller box and the valve body positioning seat is divided into by dividing plate; Wherein left chamber connects the AT valve, and is communicated with the through hole that impeller box sidewall bottom edge is offered by the micrometeor access opening, and the micrometeor access opening is the gap between indoor sidewall of impeller-driven and the impeller box lateral wall; Wherein right chamber connects the BT valve, and is communicated with the impeller box inner chamber.
Establish second rubber cushion between impeller-driven chamber and the housing.
AT valve upper end establishing weight.
Establish first rubber cushion on the shutoff face of BT valve.
High precision water meter of the present utility model has been compared following good effect with existing procucts:
1), after water swivel closes, crossed strip relies on its screen resilience that the shutoff face of CT valve is fitted in the outer face of water delivering orifice, contact pin is deep in the impeller clearance of impeller simultaneously, the rotation of restriction impeller, water meter is no longer had good luck.
2), when water clock appears in the water meter freeing port, the AT valve is open, current enter the rotation of impeller box drive impeller, meter reading through micrometeor access opening and the through hole that is communicated with impeller box.
Therefore, the utility model has been realized the high-precision measuring of water meter.
(4), description of drawings
Fig. 1 is a structural representation of the present utility model.
(5), embodiment
Further specify the utility model below in conjunction with accompanying drawing and instantiation.
As shown in Figure 1, this example comprises the housing 4 that has water inlet 5 and water delivering orifice 19, and the impeller box 29 that impeller 6 is housed is installed in housing 4.On impeller box 29, establish gear counter 3, on gear counter 3 upper shell 4, establish glass plate 26, on glass plate 26, establish protecting glass 1, between protecting glass 1 and glass plate 26, establish locking cap 2, establish sealing gasket 30 between glass plate 26 and the housing 4.
The be threaded valve cover 18 of outer end band freeing port 28 of described water delivering orifice 19 ends.Be provided with CT valve 27 between water delivering orifice 19 and freeing port 28, the shutoff face of CT valve 27 cooperates with the outer face of water delivering orifice 19, and the valve rod of CT valve 27 can be installed on the support 20 axially slidably.Establish the 3rd rubber cushion 21 between support 20 and the housing 4.Have crossed strip 22 on the valve rod of CT valve 27, be fixed with in the shutoff face of CT valve 27 and the outer face of water delivering orifice 19 contact pin 25 that can be deep into the impeller clearance of impeller 6 when closed on the shutoff face of CT valve 27.
The bottom of impeller box 29 is provided with the impeller-driven chamber 16 of lower end band screen pack 15 in housing 4.Establish second rubber cushion 17 between impeller-driven chamber 16 and the housing 4.Be provided with in the impeller-driven chamber 16 with impeller-driven chamber 16 and be the valve body positioning seat 31 of one, AT valve 9 and BT valve 10 are installed on valve body positioning seat 31.AT valve 9 upper end establishing weights.Establish first rubber cushion 11 on the shutoff face 12 of BT valve 10.Have longitudinal spring 13 on the valve rod of BT valve 10, the valve rod lower end of this BT valve 10 has spring washer 14.Two chambers about space between impeller box 29 and the valve body positioning seat 31 is divided into by dividing plate.Wherein left chamber connects AT valve 9, and is communicated with the through hole 7 that impeller box 29 sidewall bottom edge are offered by micrometeor access opening 8, and micrometeor access opening 8 is the gap between impeller-driven chamber 16 madial walls and impeller box 29 lateral walls.Wherein right chamber connects BT valve 10, and is communicated with impeller box 29 inner chambers.
When using this high precision water meter, water meter inserts, and water enters from water meter water inlet 5, and water passes screen pack 15 with AT valve 9, and BT valve 10 is pushed open and entered impeller box 29.The water that enters impeller box 29 promotes the glued membrane 24 that impeller 6 has promoted CT valve 27 simultaneously, glued membrane 24 is reduced in the groove 23 by hydraulic pressure, contact pin 25 is dragged by glued membrane 24 simultaneously, and spring 22 was compressed when contact pin 25 was drawn out from the impeller clearance, and water flows out water delivering orifice 19 and freeing port 28.AT valve 9, what BT valve 10 was opened is big less by water meter water delivering orifice 19, the decision of freeing port 28 flows.
When water clock appearred in water meter water delivering orifice 28, AT valve 9 was open earlier, and along with the aquifer yield increase of water delivering orifice 28, BT valve 10 is open.During the anhydrous outflow of freeing port 28, glued membrane 24 drives contact pins 25 and resets, and this moment, fluctuation appearred in pipeline hydraulic pressure, and impeller 6 is subjected to the control of contact pin 25 rotation can not occur.
