Embodiment Construction

[0020] A kind of filling method of intelligent transmitter measuring bellows pressure transmission medium (see figure 1 ), which includes the following steps:

[0021] ① Before filling starts, close all valves.

[0022] Open the valve II8, and use the RVP-6 vacuum pump 3 produced by Beijing Zhongke Keyi Technology Development Co., Ltd. to vacuum the inside of the flange 1 of the smart transmitter to make the vacuum inside the flange 1 of the smart transmitter reach below 1.33Pa. , in a vacuum state.

[0023] ② Use the H01-1A magnetic heating stirrer 9 produced by Shanghai Meiyingpu Constant Temperature Magnetic Stirrer Factory to stir and heat the signal transmission medium of the flange intelligent transmitter until no bubbles are generated, so that the light components and water in it are evaporated Then open valve I7, take away light component and moisture with vacuum pump 3, make oil tank 2 (volume is 5 liters) internal vacuum degree reach below 1.33Pa, thereby obtain th...

Abstract

The invention relates to a filling method for an intelligent transducer measuring film box pressure conductive medium, which comprises following steps: (1) enabling the intelligent conductive flange 1) in a vacuum state; (2) purifying the conductive medium; (3) opening the oil check valve 4), oil charging valve 5) to make the conductive medium get through the oil check valve 4), oil charging valve 5) to be filled to the intelligent conductive flange 1); (4) opening the gas discharging valve 6) at the top of the oil tank 2) for pressing the conductive medium to the intelligent conductive flange 1). The invention has the characteristic of assuring the purity of the conductive medium at the same time of enhancing the working efficiency.

Description

technical field [0001] The invention relates to a filling method for the production of a flange intelligent transmitter, in particular to a filling method for the intelligent transmitter to measure the pressure transmission medium of a bellows. Background technique [0002] The flange intelligent transmitter is composed of a basic meter, a capillary and a flange. The corrugated gap inside the flange is connected to the outside of the measuring bellows of the basic meter through the capillary. Silicone oil, as the pressure transmission medium of the flange smart transmitter measuring bellows, must be filled inside the transmitter. When the external pressure acts on the flange diaphragm to compress the inner space of the diaphragm, the silicone oil inside the diaphragm will flow to the base gauge under pressure, and the silicone oil will generate pressure on the measuring bellows of the base gauge. After the measuring bellows is pressurized, the sensor The measured signal is ...
