Abstract
The utility model discloses an installation structure of an ultrasonic transducer, comprising an ultrasonic flow tube. A side pressure hole is arranged on the ultrasonic flow tube, the ultrasonic transducer is installed in the side pressure hole, and the side pressure hole is a step hole with a larger upper part and a smaller lower part. An annular step is arranged on the outer wall of the lower part of the ultrasonic transducer, an upwards concave annular trough is arranged on the annular step, and a sealing ring is installed in the annular trough. The annular step clings to the step of the side pressure hole, and the sealing ring clings to the step surface of the side pressure hole. By adopting the structure, the upwards concave annular trough is arranged on the annular step, and the sealing ring can be well fixed by the annular trough. In addition, since the sealing ring clings to the step of the side pressure hole, a good sealing effect is achieved.
Description
Technical field
The utility model relates to a kind of physical measuring instrument, particularly relates to a kind of ultrasonic transducer mounting structure.
Background technology
Existing ultrasonic transducer mounting structure is such, on the hypersonic flow buret, have the side pressure hole, in the side pressure hole, ultrasonic transducer is installed, described side pressure hole is up big and down small stepped hole, described ultrasonic transducer bottom outer wall is provided with ring-shaped step, and described ring-shaped step is close on the step in described side pressure hole, and this kind structure is not provided with hermetically-sealed construction separately, therefore liquid flows out in the hypersonic flow buret easily, causes deficiencies such as measuring out of true; Also have a kind of structure to be, between the inwall in the outer wall of described ultrasonic transducer and side pressure hole, O-ring seal is set directly, this kind structure, after long-time the use, O-ring seal is easy to generate distortion, wear out etc., thereby also do not have the effect of sealing.
Summary of the invention
The purpose of this utility model provide a kind of good sealing effect ultrasonic transducer ultrasonic transducer mounting structure.
For achieving the above object, the technical solution of the utility model is: a kind of ultrasonic transducer mounting structure, comprise the hypersonic flow buret, on this hypersonic flow buret, have the side pressure hole, in described side pressure hole, ultrasonic transducer is installed, its main points are: described side pressure hole is up big and down small stepped hole, described ultrasonic transducer bottom outer wall is provided with ring-shaped step, on this ring-shaped step, have the ring groove of fovea superior, in this ring groove, O-ring seal is housed, described ring-shaped step is close on the step in described side pressure hole, and described O-ring seal is close to the step surface in described side pressure hole.Adopt above structure, have the ring groove of fovea superior on ring-shaped step, this ring groove can be good at O-ring seal is fixed, and simultaneously, because O-ring seal is close to the step in side pressure hole, thereby plays good sealing effectiveness.
In described side pressure hole, described pad is fixed on the described hypersonic flow buret through housing screw described ultrasonic transducer, adopts above structure through spacers, ultrasonic transducer can be limited in the described side pressure hole reliably.
Effect of the present utility model: the utility model novelty simple in structure, on the ring-shaped step on the outer wall of ultrasonic transducer bottom, have the ring groove of fovea superior, O-ring seal is close to the step in side pressure hole, thereby plays good sealing effectiveness., have and improve the life-span, be easy to advantage such as realization.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
See also Fig. 1: shown in a kind of ultrasonic transducer mounting structure, comprise hypersonic flow buret 1, on this hypersonic flow buret 1, have side pressure hole 2, in described side pressure hole 2, ultrasonic transducer 3 is installed, it is characterized in that: described side pressure hole 2 is up big and down small stepped hole, described ultrasonic transducer 3 bottom outer walls are provided with ring-shaped step 3a, on this ring-shaped step 3a, have the ring groove 3b of fovea superior, in this ring groove 3b, O-ring seal 4 is housed, described ring-shaped step 3a is close on the step in described side pressure hole 2, and described O-ring seal 4 is close to the step surface in described side pressure hole 2.
It can also be seen that in Fig. 1: described ultrasonic transducer 3 is fixed in the described side pressure hole 2 through pad 6, and described pad 6 is fixed on the described hypersonic flow buret 1 through housing screw 5.
The above only is preferred embodiment of the present utility model; it is not restriction with the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
