The invention discloses a high-precision pressure and flow measurement and control instrument, which includes a flow pressure converter, the bottom end of the flow pressure converter is fixedly connected with a first installation pipe, and the bottom end of the first installation pipe is provided with a second installation pipe. The bottom end of the first installation pipe is fixedly pierced with a reinforcement ring, and an installation sleeve is provided on the outside of the connection between the reinforcement ring and the second installation pipe, and a limiting groove is opened on the outside of the installation sleeve, and the second installation pipe An inward installation groove is opened at the bottom end of the outer side. A spring is provided at one end of the installation groove, and a restricting post is provided at one end of the spring. One end of the restricting post penetrates the installation groove. The limiting column is engaged with the installation sleeve through the limiting groove; by installing an installation sleeve on the outside of the connection between the second installation pipe and the reinforcement ring, under the action of the limiting column and the limiting groove, the self-loosening of the installation sleeve is effectively avoided. To further improve the firmness of the connection between the first installation pipe and the second installation pipe.
Description
technical field [0001] The invention belongs to the technical field of measurement and control instruments, in particular to a pressure and flow measurement and control instrument with high precision. Background technique [0002] Flow measurement and control instrument is an industrial automation instrument used to measure and control the flow and pressure of fluids such as liquid, gas or steam in pipes or open trenches. It is widely used in petroleum, chemical, metallurgy, electric power and light industry and other industries. In the existing measurement and control instruments, the installation sleeve lacks a limit, and the installation sleeve is easy to rotate under the action of external force, thereby reducing the problem of the firmness of the connection between the first installation pipe and the second installation pipe. Pressure and flow measurement and control instruments. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a h...
