Fixing mechanism for remote transmitting pressure transmitter

Abstract

The invention relates to a fixing mechanism for a remote transmitting pressure transmitter. The remote transmitting pressure transmitter comprises a remote transmitting seal component (4) arranged at a measuring end of the transmitter. The remote transmitting seal component (4) comprises a flange and a pressure measuring diaphragm sealed to a side end face of the flange. The fixing mechanism comprises an instrument stand (1) used for bearing the remote transmitting seal component (4), a protruding mounting plate (2) is arranged on the instrument stand (1), a bakelite plate (3) is connected to the mounting plate (2), and the flange of the remote transmitting seal component (4) is connected with the bakelite plate (3). According to the fixing mechanism for the remote transmitting pressure transmitter, holes are only need to be drilled on the bakelite plate, the holes are used for the installation of the instrument stand and the flange, a standard flange is adopted, additional hole drilling is not needed, and destroy on the mechanical structure of the flange is avoided, so that loading capacity of the flange cannot be influenced, the security and the reliability of the an instrument are improved, and procurement cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of transmitter installation, and in particular relates to a fixing mechanism of a remote pressure transmitter. Background technique [0002] In nuclear power plants, when a pressure transmitter with a remote diaphragm seal is used to measure a medium that is prone to crystallization, it is necessary to add heat insulating material between the medium and the mounting plate of the instrument frame to prevent the remote diaphragm of the transmitter from The medium crystallizes when cooled. like figure 1 As shown, the traditional installation method is to drill 4 holes (tapping) on ​​the outer flange end face of the remote diaphragm of the pressure transmitter, and fix the flange with the mounting plate 2 of the instrument frame 1 with bolts. Asbestos insulation is used between. like Figure 4 As shown, there are four Φ12 through holes in the middle of the existing asbestos insulation layer made of asbestos,...

AI Technical Summary

Problems solved by technology

Asbestos is a commonly used thermal insulation material in nuclear power plants, but its hardness is not high. When the flange and the mounting Additional holes are drilled on the flange of the transmitter. Such a transmitter is a non-standard design that requires special design by the manufacturer and may affect the pressure bearing capacity of the flange.
