A kind of through type W reflection-type ultrasound wave pipeline section structure capable of washing
Technical field
The utility model relates to a kind of improvement of pipeline section structure of ultrasonic measurement flow, relates to a kind of through type W reflection-type ultrasound wave pipeline section structure capable of washing particularly.
Background technology
Ultrasonic applications has pinpoint accuracy, without hindrance measurement and lower cost in measuring the fluid flow aspect, has become the first-selection in flow measurement field.In recent years, the ultrasonic measurement fluid flow also is widely used in civilian measuring instrument industry, like ultrasound wave water meter, ultrasonic calorimeter or the like.The ultrasound wave instrument of most of manufacturer production all is to utilize the ultrasound wave mistiming that following current propagation and adverse current are propagated in fluid this principle that is directly proportional with rate of flow of fluid to measure fluid flow; The measurement transducer of tubule run-off generally adopts the W type to install; Improve measuring accuracy through prolonging the transmission range of ultrasound wave in little caliber; On the pipeline section structure, most of producer adopts is that the reflector plate of reflection supersonic wave is installed in pipe interior, and the shortcoming of this kind way is following: (1) ultrasonic reflections sheet can produce dirt in the reflector plate surface in operational process for a long time; Influence measuring accuracy, reflector plate inconvenience is cleaned; (2) reflector plate is installed in pipe interior, has taken space in the pipeline, and crushing is bigger, and causes line clogging easily, not only influences the accuracy of ultrasound wave metering, also can cause ultrasonic flow meter normally not measure.
Summary of the invention
The purpose of the utility model provides a kind of through type W reflection-type ultrasound wave pipeline section structure capable of washing of blocking, improving measuring accuracy capable of washing, difficult.
To achieve these goals, the technical scheme of the utility model is described below:
A kind of through type W reflection-type ultrasound wave pipeline section structure capable of washing; Contain flow measurement straight tube body, flow inlet, water export, flow to a mouthful transducer mounting pipe, flow export transducer mounting pipe, flow to oral reflex sheet mounting seat, flow export reflector plate mounting seat, water inlet reflector plate, water delivering orifice reflector plate, sleeve pipe, top reflector plate; It is characterized in that: flow to the vertical respectively flow measurement straight tube body that is located at flow inlet end and water export end of mouthful transducer mounting pipe and flow export transducer mounting pipe above; It is inboard that the top reflector plate is stuck in the sleeve pipe top; Sleeve pipe and flow measurement straight tube body adopt screw to fix; Flow to a mouthful transducer mounting pipe effluent measurement amount straight tube body respectively vertical be provided with relative and flow to oral reflex sheet mounting seat and flow export reflector plate mounting seat with flow export transducer mounting pipe; Both become 30-45 degree angle with flow measurement straight tube body water (flow) direction; The transducers transmit ultrasonic waves that is installed in the stream entrance point arrives flow export end transducer through triple reflection, realizes the collection of flow signal.
The described oral reflex sheet mounting seat that flows to adopts screw to be connected with flow export reflector plate mounting seat and flow measurement straight tube body, convenient water inlet reflector plate and the water delivering orifice reflector plate of cleaning.
Described sleeve pipe places in the flow measurement straight tube body.
The beneficial effect of the utility model is:
(1) a kind of through type W reflection-type ultrasound wave pipeline section structure capable of washing of the utility model patent can prevent that reflector plate from producing dirt in long-play because reflector plate is capable of washing, and the reflection line can be not influenced, improves measuring accuracy.
(2) a kind of through type W reflection-type ultrasound wave pipeline section structure capable of washing of the utility model patent adopts the through type design, has reduced crushing, thereby improves measuring accuracy.

Embodiment
Be described in further detail below in conjunction with embodiment and description of drawings technical scheme the utility model.
Shown in accompanying drawing 1; A kind of through type W reflection-type ultrasound wave pipeline section structure capable of washing contains flow measurement straight tube body, flow inlet 10, water export 5, flows to a mouthful transducer mounting pipe 1, flow export transducer mounting pipe 3, flow to oral reflex sheet mounting seat 9, flow export reflector plate mounting seat 7, water inlet reflector plate 8, water delivering orifice reflector plate 6, sleeve pipe 4, top reflector plate 2; Flow to mouthful transducer mounting pipe 1 and the flow export transducer mounting pipe 3 vertical respectively flow measurement straight tube body tops that are installed on flow inlet 10 and water export 5; It is inboard that top reflector plate 2 is stuck in sleeve pipe 4 tops; Sleeve pipe 4 adopts screw to fix with flow measurement straight tube body; Flow to mouthful transducer mounting pipe 1 and flow to oral reflex sheet mounting seat 8 and flow export reflector plate mounting seat 7 with flow export transducer mounting pipe 3 relative vertical respectively being provided with of an effluent measurement amount straight tube body; Both become 30-45 degree angle with flow measurement straight tube body water (flow) direction; The transducers transmit ultrasonic waves that is installed in the stream entrance point arrives flow export end transducer through triple reflection, realizes the collection of flow signal.
Flow to oral reflex sheet mounting seat 9 and adopt screw to be connected, convenient water inlet reflector plate 8 and the water delivering orifice reflector plate 6 of cleaning with flow export reflector plate mounting seat 7 and flow measurement straight tube body.Sleeve pipe 4 places in the flow measurement straight tube body.
