Description
Technical field
Metering field is the utility model is related to, more particularly, to a kind of flowmeter.
Background technology
When ultrasonic flowmeter is propagated by ultrasonic wave in the fluid of flowing, the information of rate of flow of fluid is recorded, is then led to
The flow velocity that the ultrasonic wave can that sensor receives detects fluid is crossed, so as to be converted into flow, the flow in pipeline is entered
Row test.But water-carrying capacity test interface is of all kinds, flowmeter not only needs to be connected with standard water pipe sometimes, also needs non-with other
The instrument connection of standard class is used cooperatively, and traditional flowmeter can not be applicable.
Utility model content
Based on this, the utility model is to overcome the flowmeter of prior art can not coordinate with the instrument of other non-standard classes
A kind of the defects of use, there is provided flowmeter.
Its technical scheme is as follows：
A kind of flowmeter, for being connected with water pipe or other meters, including：Table provided with first interface and second interface
Body, the first interface are connected with water pipe, and the second interface is connected with other meters, and the external diameter of the second interface is less than the
The external diameter of one interface.Wherein first interface is water inlet, and second interface is delivery port, and fluid enters table body by first interface
Afterwards, table body is calculated flow, and subsequent fluid flows out table body by second interface.
The technical program first interface is standard interface, and the flowmeter is connected by first interface with standard water pipe, in addition,
The first interface can be also connected with the standard interface of other meters, when flowmeter second interface need to be with small-bore non-standard class
When meter connects, segment standard switching water pipe, and the second interface external diameter of the flowmeter of the technical program need to be generally further provided with
Less than first interface, directly second interface can be inserted in the socket of non-standard class meter, plug in construction effectively solves tradition
By standard transfer water pipe thread switching loosen after drainage, and need not be further provided with transfer water pipe.Also, due to stream
The detection of gauge is strict to the requirement of flow size criteria, but the utility model second interface is delivery port, and first interface is water inlet
Mouthful and be standard interface, fluid enters table body via standard interface, and progress flow detection is finished afterwards just by second interface stream
Go out, therefore, detection of the table body to flow can't be influenceed by changing the size of second interface.
In one of the embodiments, in addition to second interface the adapter matched, in the first end of the adapter
Footpath matches with the external diameter of second interface, the second end internal diameter and water pipe to be connected or the external diameter of other meters of the adapter
Match somebody with somebody.When second interface arranges adapter, make it more stable with the connection of other meters, prevent connection from releasing.
In one of the embodiments, the screw thread coordinated with water pipe, the second interface are provided with outside the first interface
Outside is provided with the groove coordinated with adapter.In one of the embodiments, it is provided with water proof ring in the groove.Water proof ring blocks
Hydraulic pressure so that adapter is by internal pressure.
In one of the embodiments, the table body includes measurement pipeline and two peaces being arranged at intervals on measurement pipeline
Hole, the first interface and second interface are filled located at the both ends of measurement pipeline, the first interface is water inlet end, and second interface is
Water side, the mounting hole are located between first interface and second interface.The mounting hole is used for the measuring cell for installing table body,
Such as reflection subassembly, sensor etc..
In one of the embodiments, the plane where the opening of the mounting hole and first interface and/or second interface
The plane at place is vertical.Therefore, measuring cell by first interface and second interface without being installed, first interface and/or second
The size of interface changes the installation for having no effect on measuring cell, and measuring cell directly can be fit into by the opening of another plane
In mounting hole.
In one of the embodiments, the table body also includes the measurement such as reflection subassembly, sensor, wiring board and output end
Element, the reflection subassembly is in mounting hole, and the sensor is above reflection subassembly, and the sensor and circuit
Plate, output end are electrically connected with successively.The ultrasonic reflections of fluid to sensor, sensor are transmitted a signal to line by reflection subassembly
Road plate, then transmitted by output end to external device.
In one of the embodiments, the mounting hole interior edge hole week is provided with a circle boss, and the reflection subassembly is set up in
On boss, it is easy to fix the reflection subassembly.
In one of the embodiments, the reflection subassembly includes reflector plate and the support frame located at reflector plate both ends, institute
The T-shaped structure of support frame is stated, one end of support frame is connected with reflector plate, and the other end is set up on the boss in mounting hole.
In one of the embodiments, the inner wall of the hole installing is provided with neck, and the neck matches with support frame, makes support
Frame is arranged in neck, and one end is set up on boss, is improved the stability of reflection subassembly installation, it is not moved with current
It is dynamic.
The beneficial effects of the utility model are：
The second interface external diameter of the flowmeter of the technical program is less than first interface, directly can insert second interface nonstandard
In the socket of quasi- class meter, plug in construction effectively solves the leak after traditional water pipe thread switching loosening of being transferred by standard
Phenomenon, and water pipe of transferring need not be further provided with.Also, because the detection of flowmeter is strict to the requirement of flow size criteria, but this
Utility model second interface is delivery port, and first interface is water inlet and is standard interface, and fluid enters table via standard interface
Body, just flow out by second interface after flow detection finishes, therefore, table can't be influenceed by changing the size of second interface
Detection of the body to flow.
