Problems solved by technology

At present, there is no special device for positioning and calibrating the position of the reflector on the market. Once the position of the reflector deviates, it will affect the calculation of the heat value, thereby affecting the final result, making the obtained result different from the actual value. There is a large difference, which reduces the accuracy of the heat meter

Abstract

The invention provides a positioning tool for reflection pillars in a valve, belonging to the technical field of machinery. The positioning tool solves the problem that a special tool for positioning the reflection pillars does not exist in the prior art. The positioning tool for reflection pillars in the valve comprises a positioning base and cylindrical positioning sleeves. Two cylindrical reflection pillar dies are arranged on the positioning base. Positioning surfaces with opposite tilting directions and the same tilt angle are respectively arranged at the end parts of the reflection pillar dies. The inner diameter of the positioning sleeves is matched with the outer diameter of the reflection pillar dies. The positioning sleeves are sheathed on the reflection pillar dies and the positioning surfaces are in the positioning sleeves. The positioning tool for reflection pillars in the valve has the advantages of simplicity in operation, high reflection pillar positioning accuracy, wide application scope and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a positioning tool, in particular to a positioning tool for a reflective column in a valve. Background technique [0002] At present, the structure of the ultrasonic heat meter equipped with a reflection device includes a meter body, two ultrasonic sending and receiving devices vertically installed on the meter body, a reflecting device arranged inside the meter body, and two ultrasonic sending and receiving devices connected respectively. Electronic circuit and flow accumulation display system. Its working process is as follows: one of the ultrasonic transmitting and receiving devices including the ultrasonic transducer emits ultrasonic waves, the ultrasonic waves are reflected by the reflecting device and propagate along the direction of liquid flow, and are received by another ultrasonic transmitting and receiving device; this ultrasonic transmitting and receiving device emits ...
