Two class of degree formula water meter originates from Britain, and the development of water meter has nearly 200 years history, when selecting water meter specification, should first estimate
Then the size and range of flow of used flow under normal conditions selects the water of that specification of the common flow closest to the value
Table is as preferred.Drawback of the prior art is that water meter precision is not high enough.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of Su He water meter measurement mechanism, impeller
The box watchcase gulf wall construction that design one is gradually increased from water inlet direction to water outlet direction, border encryption seal and watchcase interference are matched
Be combined dress, when water is flowed into from watchcase water inlet, encounter the gulf wall that impeller box is gradually increased along water (flow) direction, the speed of water flow by
Gradually accelerate, push the quick rotation of impeller, improves accuracy of water meter, minimum initial-flow and high range ratio.
The purpose of this utility model is achieved through the following technical solutions:
A kind of Su He water meter measurement mechanism, the mechanism are made of shell of water flowmeter, impeller box, impeller, sealing ring, before the watchcase
After be respectively arranged with water inlet interface and water outlet mouthpiece, the impeller is mounted in impeller box, the entirety that impeller and impeller box are formed
In watchcase, the sealing ring forms sealing structure between watchcase, impeller box, wherein the water inlet of impeller box and water inlet
Interface docking, the water outlet of impeller box are docked with water outlet mouthpiece, the watchcase one circle of design from water inlet direction to water outlet direction
The gulf wall construction gradually increased.
As the further improvement of this programme, the gulf wall construction from water inlet interface respective side be starting point to water outlet mouthpiece pair
Side is answered to gradually increase, so that watchcase end face forms inclined-plane, the part between the inclined-plane minimum point and highest point is gulf wall construction.
As the further improvement of this programme, the water inlet of the impeller box is evenly distributed on impeller outer box wall, so that water
Stream can enter in impeller box from gulf wall construction overlay area and uncovered area.
As the further improvement of this programme, interference fit is formed between the sealing ring and shell of water flowmeter, impeller box.
As the further improvement of this programme, the water inlet interface and water outlet mouthpiece are provided with connection screw thread.
As the further improvement of this programme, the water inlet is at least four.
As the further improvement of this programme, movement mechanism is adjusted in the impeller box setting.
The beneficial effects of the utility model are: this programme in impeller box watchcase from water inlet direction to water outlet direction by setting
The one gulf wall construction gradually increased of meter, border encrypt seal and watchcase interference fit assembling, when water is flowed into from watchcase water inlet, edge
Water (flow) direction encounter the gulf wall that impeller box is gradually increased, the speed of water flow ramps up, push the quick rotation of impeller, improve
Accuracy of water meter, minimum initial-flow and high range ratio.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is this practical shell of water flowmeter gulf wall construction schematic diagram.
Specific embodiment
The technical solution of the utility model, but the protection scope of the utility model are described in further detail with reference to the accompanying drawing
It is not limited to as described below.
As shown in Figure 1,
A kind of Su He water meter measurement mechanism, the mechanism are made of watchcase 1, impeller box 2, impeller 3, sealing ring 4, adjusting core 7.
Water inlet interface 5 and water outlet mouthpiece 6 are respectively arranged with before and after shell of water flowmeter 1, the impeller 3 is mounted in impeller box 2, impeller 3 and leaf
What wheel box 2 was formed is integrally located in shell of water flowmeter 1, and the sealing ring 4 forms sealing structure between shell of water flowmeter 1, impeller box 2,
It adjusts core to be located on impeller box, flow of inlet water size is adjusted, wherein the water inlet 21 of impeller box 2 is docked with water inlet interface 5, leaf
The water outlet of wheel box 2 is docked with water outlet mouthpiece 6, i.e., watchcase 1 in this programme, impeller box 2, impeller 3, sealing ring 4, adjusting core 7 it
Between mounting structure it is identical with the mounting structure of conventional water meter.The improvement of this programme is, shell of water flowmeter 1 is from water inlet direction
The gulf wall construction 12 gradually increased to one circle of water outlet direction design, is designed specifically to gulf wall construction 12 and is corresponded to by water inlet interface 5
Side is that starting point is gradually increased to 6 respective side of water outlet mouthpiece, so that 1 end face of shell of water flowmeter forms inclined-plane, the inclined-plane minimum point and highest
Part between point is gulf wall construction 12, as shown in Fig. 2, 11 indicate flow inlet direction, it can be seen that 1 left side of shell of water flowmeter is low
Right side height forms inclined-plane, and water flow flow direction is as shown in outside arrow in Fig. 2, it can be seen that water flow is flowed by 11, along water meter
Clockwise flow in shell 1, in flow process since gulf wall construction 12 gradually increases so that water flow reach water outlet side when water flow
Speed is maximum, represented by black arrow is water velocity in Fig. 2, arrow is more intensive, and water velocity is bigger, the speed of water flow
