Problems solved by technology

However, the above patents use a first-level sensor. If it is applied to measure the pressure of liquid metal sodium, there is a danger of sodium contacting with air, so it is not suitable as a pressure sensor for liquid metal sodium.

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the drawings:

[0023] See figure 1 , The present invention includes sodium connector, elastic stress sheet, sodium-sodium-potassium alloy pressure sensing box, sodium-potassium alloy-air pressure sensor and pressure gauge. The sodium connection pipe is connected from the main pipe where the pressure needs to be measured, and is connected to the sodium-sodium-potassium alloy pressure sensing box. There is an elastic stress sheet in the middle of the sodium-sodium potassium alloy pressure sensing box, and the elastic stress sheet transmits the pressure of sodium from one side to the other One side of sodium potassium alloy makes the pressure on both sides consistent. After the sodium-potassium alloy in the sodium-sodium-potassium alloy pressure sensing box is connected, connect a sodium-potassium alloy-air pressure sensor, and the pressure signal is changed into an electrical signal in the s...

Abstract

The invention discloses a liquid-state metallic sodium experiment loop pressure sensor. The pressure sensor comprises: a sodium adapter, an elastic strain gauge, a sodium-sodium potassium alloy pressure sensor box, a sodium potassium alloy-air pressure sensor and a pressure gauge. The sodium adapter is connected with a main pipe. Liquid state sodium can enter into the sodium-sodium potassium alloy pressure sensor box through the sodium adapter. The elastic strain gauge is in the middle of the pressure sensor box. Two sides of the strain gauge are the liquid state sodium and liquid-state sodium potassium alloy. The liquid-state sodium potassium alloy enters into the sodium potassium alloy-air pressure sensor through the pipe. A pressure signal is converted into an electric signal in the pressure sensor. The converted electric signal is displayed through the pressure gauge. Two-stage sensing is used so that the sodium can not contact with the air. A sealing property is good. A temperature compensation circuit is used in a bridge circuit of the sodium potassium alloy-air pressure sensor. An error generated by temperature can be avoided and overall measurement accuracy can be increased.

Description

Technical field [0001] The invention belongs to the technical field of pressure measurement of liquid metal sodium, and specifically relates to a sensor device used in a liquid metal sodium test circuit to measure the pressure of liquid metal sodium. Background technique [0002] Because of its good thermal conductivity, fluidity and good neutron performance, liquid sodium has become the preferred coolant material for fast neutron reactors. Therefore, in recent years, the experimental research on various properties of liquid metal sodium has gradually deepened. When carrying out the liquid metal sodium experiment, it is necessary to measure the pressure of liquid metal sodium at some positions, especially before and after the electromagnetic pump. Due to the unique chemical properties of sodium, it cannot be in contact with air and water, so a special pressure measuring device is required for liquid sodium. The pressure is measured. [0003] The basic working principle of the liqu...
