According to the invention, through application of the structure, the device has the advantages that the structure is novel; installation is convenient; the service life is long; the use cost is low; and the volume could be adjusted at any time according to the environmental temperature changes, etc.
Description
Technical field
The present invention relates to flow measurement technical field, the ultrasonic flow rate measurement device that specifically a kind of anti-ice is frozen.
Background technology
It is known that, existing ultrasonoscope scale is by table body, integrator and transducer assemblies composition, described table body sidewall is provided with transducer and installs body, it is installed with carriage assembly in described table body, it is installed with transducer assemblies in described transducer installing pipe body, described transducer assemblies are connected with integrator, when measuring flow, the principle propagated in a liquid by one or more pairs of transducer assemblies is recording sound wave forward, reverse propagation speed differential and calculate the flow velocity of fluid, again outflow is calculated by the integral formula in integrator, when installing transducer assemblies, generally transducer assemblies pressing plate is fixed in transducer installing pipe body, to prevent the fluid in table body from overflowing, the substantive deficiency of this structure is：Because transducer assemblies pressing plate is fixed in transducer installing pipe body, when using in winter, after fluid in table body is frozen, its volume becomes big, because table body typically adopts copper alloy or stainless steel, there is good ductility, will not bursting by freezing, become big after energy cannot discharge and to lead to ultrasonic transducer assembly to rise broken, and then lead to ultrasonic flowmeter cannot use, need to change and freeze broken transducer assemblies, cause use cost and installation cost to increase.
Up to the present, the antifreezing measures in cold season for this transducer assemblies also cannot solve.
Content of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, provide the ultrasonic flow rate measurement device that a kind of structure is novel, easy for installation, long service life, use cost are low, can freeze according to the anti-ice that the change of ambient air temperature adjusts volume at any time.
The technical solution adopted for the present invention to solve the technical problems is：
The ultrasonic flow rate measurement device that a kind of anti-ice is frozen, including table body, integrator and transducer assemblies, described table body sidewall is provided with transducer and installs body, it is characterized in that body installed by described transducer is provided with transducer position adjusting means, it is beneficial to and the change that transducer assemblies adapt to ambient temperature is adjusted by transducer position adjusting means, avoid the deficiency of table body and transducer assemblies easy bursting by freezing in severe cold environment, significantly improve the service life of ultrasonic flow rate measuring.
Transducer position adjusting means of the present invention includes compression spring、Mounting flange、Connect pressing plate、Pressure cover and O-ring seals，Described transducer is installed body upper end and is provided with mounting flange，Described connection pressing plate lower end is fixedly connected with mounting flange，Upper end is fixedly connected with pressure cover，Described transducer assemblies are installed inboard wall of tube body through O-ring seals and transducer and are tightly connected，Described transducer assemblies upper end is provided with compression spring，Described compression spring lower end is inconsistent with transducer assemblies，Upper end is inconsistent with pressure cover，After the fluid in table body is frozen，The volume of its swell promotes transducer assemblies to install body axial displacement along transducer，After the fluid of table body is defrosted，Transducer assemblies return in the presence of compression spring，Table body and transducer assemblies are made to avoid the risk of bursting by freezing，Extend the service life of table body，Greatly save use cost.
The present invention, due to adopting said structure, has the advantages that structure is novel, easy for installation, long service life, use cost are low, can adjust volume at any time according to the change of ambient air temperature.

Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings：
As shown in drawings, the ultrasonic flow rate measurement device that a kind of anti-ice is frozen, including table body 1, integrator and transducer assemblies 4, described table body 1 side wall is provided with transducer and installs body 10, shown transducer is installed body and can be arranged on table body side, as shown in accompanying drawing 1,2；The both sides of table body can also be arranged on, as shown in Figure 4；Can adopt in table body of the present invention and be provided with transducer reflection receivable part, described transducer reflection receivable part can be provided with the structure of mirror surface using wall in table body, the mounting means of the mirror support assembly 2 of plug-in type can also be adopted, this is prior art, no longer describe in detail, the annexation of described integrator and transducer assemblies 4 is same as the prior art, this does not repeat, it is characterized in that body 10 installed by described transducer is provided with transducer position adjusting means, it is beneficial to and the change that transducer assemblies adapt to ambient temperature is adjusted by transducer position adjusting means, avoid the deficiency of table body and transducer assemblies easy bursting by freezing in severe cold environment, significantly improve the service life of ultrasonic flow rate measuring.
Transducer position adjusting means of the present invention includes compression spring 6、Mounting flange 11、Connect pressing plate 7、Pressure cover 12 and O-ring seals 3，Described transducer is installed body 10 upper end and is provided with mounting flange 11，Described connection pressing plate 7 lower end is fixedly connected with mounting flange 11 with screw 8 through packing ring 9，Upper end is fixedly connected with pressure cover 12，Described transducer assemblies 4 are installed body 10 inner wall sealing through O-ring seals 3 and transducer and are connected，Described transducer assemblies 4 upper end is provided with compression spring 6，Described compression spring 6 lower end is inconsistent with transducer assemblies 4，Upper end is inconsistent with pressure cover 12，After the fluid in table body 1 is frozen，The volume of its swell promotes transducer assemblies 4 to install body 10 axial displacement along transducer，After the fluid of table body 1 is defrosted，Transducer assemblies 4 return in the presence of compression spring 6，Table body 1 and transducer assemblies 4 are made to avoid the risk of bursting by freezing，Extend the service life of table body，Greatly save use cost.
The present invention is in when using under cold state in the winter time, after fluid in table body 1 is frozen, the volume of fluid gradually swell, the volume of swell promotes transducer assemblies 4 to install body 10 axial displacement along transducer, through O-ring seals 3 and transducer, body 10 is installed due to transducer assemblies 4 to be tightly connected, it is to avoid move on the fluid in table body 1 and overflow；When ambient temperature is under thawed state, after the fluid of table body 1 is defrosted, the fluid in table body 1 gradually melts, and its volume gradually restores, transducer assemblies 4 then under the tension force effect of compression spring 6 return it is ensured that the normal use of table body 1 and transducer assemblies 4.
