Embodiment
Further illustrate the utility model below in conjunction with drawings and Examples, the content of embodiment is not as the restriction to protection domain of the present utility model.
The utility model relates to a kind of single rotor ultrasonic flowmeter, and its structure is simple and be applicable to the accurate measurement of medium.
Fig. 1 shows the longitudinal sectional view of single rotor ultrasonic flowmeter of the present utility model.As shown in Figure 1, similar with existing spinner-type flowmeter, single rotor ultrasonic flowmeter of the present utility model comprises housing 1.The both sides of described housing 1 are respectively arranged with entrance 2 and outlet 3.Wherein, described entrance 2 is for the inflow of medium to be measured.Described outlet 3 is for the outflow of the medium after measuring.In the utility model, preferably, described entrance 2 is provided with inlet flange 11, is connected with medium service by described inlet flange 11.Described outlet 3 is provided with discharge flange 12, is connected with medium outflow conduit by described discharge flange 12.
Different from existing spinner-type flowmeter, as shown in Figure 1, in the utility model, in described housing 1, be provided with a circular cavity 4.Meanwhile, in described circular cavity 4, a rotor 5 is installed.Described rotor 5 is made up of four the identical blades being mutually 90 degree.Wherein, the length of described blade is identical with the radius of described circular cavity 4 thus make described rotor 5 described circular cavity 4 is separated into four identical cavitys be isolated from each other, that is, the cavity I shown in Fig. 1, cavity II, cavity III and cavity IV.And as shown in Figure 2, described rotor 5 is not rotate by the thrust of media flow, but is driven by the motor 13 be positioned at outside described housing 1.Like this, the rotation of described rotor 5 is made not to be subject to the flow stability of medium and the restriction of flowing velocity.
Meanwhile, as shown in Figure 1, the bottom of the side of the close described entrance 2 of described circular cavity 4 is provided with inlet port 14.Described inlet port 14 is connected with described entrance 2 by admission chamber 6.Preferably, on described admission chamber 6, inwall is positioned on the surface level at the central point place of described circular cavity 4, so that medium enters into be communicated with it cavity of described circular cavity 4, in the cavity I namely shown in Fig. 1 from described admission chamber 6.And the top in described admission chamber 6 is provided with ultrasonic liquid level sensor 8.By described ultrasonic liquid level sensor 8, the liquid level of the medium in described admission chamber 6 can be measured.Preferably, described ultrasonic liquid level sensor 8 is roughly concordant with the surface level at the central point place of described circular cavity 4.
In addition, the top of the side of the close described outlet 3 of described circular cavity 4 is provided with flow export 15.Preferably, described flow export 15 is signed on the surface level at the central point place being positioned at described circular cavity 4.Described flow export 15 is connected with described outlet 3 by liquid storage cylinder 7.Like this, make the cavity be communicated with described liquid storage cylinder 7 of described circular cavity 4, that is, the medium in the cavity III shown in Fig. 1 can flow in described liquid storage cylinder 7.
