Description
Technical field
The invention belongs to compound water metre, integral deck compound water metre is especially belonged to.
Background technology
Compound water metre is commonly called as primary and secondary water meter, and the water meter for planting bore by a big young waiter in a wineshop or an inn is constituted.The metering model that running water passes through water meter
Enclose the maximum stream flow from small diameter watermeter minimum discharge to large-diameter water meter.So it is maximum current measurement range, under flow
The minimum mechanical water meter of limit.It is to automatically control current according to the size for flowing through water by flow conversion control valve to flow through bypass osculum
Footpath subtabulation flows through the bigbore master meter of main road simultaneously, and in water consumption hour, flow conversion control valve is closed, by pair
Meter amount, master meter is not measured；When flow exceedes certain value, flow conversion control valve is opened, and master meter, subtabulation are measured simultaneously；Stream
When amount drops to certain value, flow conversion control valve is closed again, subtabulation metering.
Traditional compound water metre uses split-type structural substantially, there is two kinds of structures：Split type casing or integral housing with
Split type core, Split type casing：As shown in figure 1, using large-diameter detachable formula horizontal screw wing type water meter and small-bore rotor
Formula water meter is attached by taking over, connecing the parts such as elbow, and assembling structure is complicated, and assembly parts are various, often due to close during assembling
Envelope problem causes housing leak, and quality, volume are larger, installs and safeguards cumbersome.
Integral housing and Split type core, i.e., using large-diameter detachable formula horizontal spiral type water as shown in Figure 2,3
The housing that table is lengthened installs small diameter watermeter and flow diverter valve additional with blind flange, so as to reach the purpose of metering water volume total amount.
The direction of arrow is water (flow) direction, and its structure is complex, the cavity uniform diameters of outlet passage, while there is flow diverter valve
In the presence of causing current moment to be slowed down, metered pressure loss is larger, influences certainty of measurement.
The content of the invention：
Present invention mainly solves problem be directed to the deficiencies in the prior art, there is provided a kind of simple structure, metered pressure loss it is small,
Certainty of measurement integrated machine core compound water metre high.
The technical problem to be solved in the present invention is achieved through the following technical solutions, integrated machine core compound water metre, its
Being characterized by it includes integral type watchcase, integral deck support, master meter, subtabulation and flow control switching valve, integral type machine
The sprue of master meter metering and the branch flow passage of subtabulation metering are designed with core support, branch flow passage is located at the upper left of sprue
Side（In face of Way in）, master meter measuring mechanism is provided with sprue, flow control switching valve is arranged on master meter measuring mechanism
In the sprue of water outlet side, the runner of the cross section of fluid channel product more than flow control switching valve front end of flow control switching valve water side
Sectional area, the just watchcase to master meter impeller assembly are provided with master meter gauge assembly, and subtabulation measuring mechanism is provided with branch flow passage,
The watchcase for facing subtabulation measuring mechanism is provided with the gauge assembly of subtabulation.
It is well known that current are by after valve body, water flow pressure can decline, existing compound water metre outlet passage area is in valve
Body rear and front end is held essentially constant, and constant by moment water flow space after valve body, the pressure loss cannot make up, and the present invention by
Radially vertical with installation pipeline with the distribution of master meter in subtabulation, width increases, and makes have certain on integral housing width
Extension, water outlet and the master meter delivery port of subtabulation mutually converge, so that the sectional area of master meter water outlet increases, water is flowed through
Moment space increase after valve body is crossed, water flow pressure is gone up, so as to reduce the pressure loss, reaches and make up current by caused by valve body
The pressure loss.Width of the present invention increases, and length direction shortens, and closer to square, the shape of water meter chamber is generally four directions
Shape, so activity space of the present invention in water meter chamber is big, the applicable less table well of water meter of same caliber.
Subtabulation uses positive displacement measuring mechanism.Low discharge precision is higher.
Master meter measuring mechanism uses spiral type impeller measuring mechanism.
Using integral type opposite sex sealing ring, special-shaped seal ring has two seal faces to sealing means, and one is that blind flange is close
Envelope, is placed between blind flange and integral type watchcase, and another is sealed for shell ends normal thereto, is placed in integral deck support
Between integral type watchcase.
Sealing system of the invention have also been made great improvement, and above two water meter is more due to composition surface, the position to be sealed
Put also many, such as：At the independent sealed circle of split type sealing mechanism at least flange, reversal valve at independent sealed circle, measuring mechanism
Independent sealed circle.The sealing of Split type casing is more：Independent sealed circle, measurement at two independent sealed circles of flange, reversal valve
Independent sealed circle at mechanism, at subtabulation adapter etc..The possibility of more leaks is also bigger at sealing, only one of which sealing of the present invention
Circle, while sealing two end faces, due to being that once injection is made, does not have interface, compared with two end faces, two sealings of sealing ring
Effect is good.
Blind flange end sealing ring part is designed with the rubber cylinder pin for coordinating positioning with blind flange, and phase is designed with blind flange
The pin-and-hole of cooperation, the inner side of shell ends sealing ring part be designed with dovetail wedge, be designed with for coordinating swallow on integral deck
Tail wedge prevents from assembling the dovetail groove for coming off.Sealing ring is set to be accurately positioned with the end face for being sealed, firmly engagement.
Flow channel entry point is provided with rectification muscle.Make water flow stationary using rectification muscle, certainty of measurement is high.
Subtabulation check valve is designed with subtabulation measuring mechanism.Water meter upside-down mounting is prevented, aqueous reflux causes counter to reverse, and causes
Metering is inaccurate.
Subtabulation counter uses vacuum sealing mode.Reading is forever directly perceived, clear, it is to avoid the influence of weather makes reading form
Produce water smoke.
Compared with above-mentioned traditional compound water metre, the present invention has abandoned traditional Split watchcase and Split type core
Structure, using integral deck, makes the metering performance of water meter more preferably, and certainty of measurement is high, contraction in length, takes up space and also reduce,
It is more convenient for I＆M of the water meter on water supply line, a sealing ring there are two seal faces, effectively prevents sealed interface
Place's leak.This novel product has simple structure, and metered pressure loss is small, novel, and dependable performance stabilization, stain resistance is strong,
Can be measured exactly under larger flow and less flow, the features such as long service life.
