Embodiment 1

[0037] like Figure 1-6 As shown in the figure, a low-loss temperature and pressure composite sensor air nozzle includes a one-way valve core 1, a one-way valve body 2, a control valve core 6, a control valve body 8, a temperature and pressure sensing core 13, and bolts 11;

[0038] One end of the one-way valve body 2 is connected to one end of the control valve body 8 , and the internal passage of the one-way valve body 2 communicates with the internal passage of the control valve body 8 ;

[0039] The one-way valve spool 1 is located in the inner passage of the one-way valve body 2, the control valve spool 6 is located in the inner passage of the control valve body 8, and the control valve spool 6 The internal passage communicates with the internal passage of the one-way valve spool 1;

[0040] The temperature and pressure sensing core 13 is located in the installation groove of the control valve body 8; the temperature and pressure sensing core 13 collects the temperature...

Embodiment 2

[0061] In this embodiment, on the basis of Embodiment 1, an air release valve 9 is provided on the outside of the control valve body 8 , and the air release valve 9 is screwed to the control valve body 8 .

[0062] The function of the air release valve 9 is to discharge the residual gas in the inner cavity before or after the test, so as to prevent interference with the test test, and the installation position of the air release valve 9 is opposite to the installation position of the voltage stabilization induction core 13 .

[0063] The specific connection relationship between the air release valve 9 and the control valve body 8 is as follows: the air release valve 9 is installed to the control valve body through a threaded connection, and in the working state, the front end cone surface of the air release valve 9 corresponds to the position of the control valve body 8 The cone surface of the inner hole forms a sealing effect. There is a small gap at the connection position b...

Embodiment 3

[0065] This embodiment is further preferred on the basis of the above-mentioned embodiment, the temperature and pressure sensing core 13 is connected to the signal line 14;

[0066] The signal line 14 is used to output the temperature and pressure data of the measured gas detected by the temperature and pressure sensing core 13 . The temperature and pressure sensing core 13 can be a temperature and pressure sensor, or other temperature and pressure detection devices with equivalent functions.

[0067] The temperature and pressure sensing core 13 collects the temperature and pressure values ​​in the test system or the test end, and outputs the collected temperature and pressure values ​​as digital signals through the signal line 14, so as to achieve the purpose of real-time monitoring of test system parameters.

Abstract

The invention discloses a low-loss temperature and pressure composite sensor air nozzle, comprising a check valve core, a check valve body, a control valve core, a control valve body, a temperature and pressure sensing core, and a bolt; One end of the valve body is connected to one end of the control valve body, and the temperature and pressure sensing core is located in the installation groove of the control valve body; the temperature and pressure sensing core collects the temperature and pressure of the gas to be measured, pressure; one end of the one-way valve spool is connected with one end of the control valve spool, and the other end of the control valve spool is connected with a bolt. In this technical solution, a temperature and pressure sensing core body is arranged in the installation groove of the control valve body. When the gas enters the control valve core and the internal channel of the control valve body, the temperature and pressure of the gas can be detected together, so as to realize Multi-parameter measurement function; and the temperature and pressure sensing core is located inside the valve body of the control valve, which reduces the interference of the external environment to the component during the test process.

Description

technical field [0001] The present application relates to the technical field of sensors, in particular to a low-loss temperature-pressure composite sensor air nozzle. Background technique [0002] Sensors are important components in industrial systems. The existing technologies in the sensor field are mature and the measurement indicators are constantly improving. However, most sensors only support single-parameter measurement. For the measurement of multi-parameter signals, the signal types and function coverage are very narrow. , far from meeting the growing needs of the development of automated monitoring technology. [0003] In the field of machinery manufacturing, especially in the air pressure sealing test process in the aviation industry, it is usually necessary to monitor whether the temperature and pressure of the compressed gas injected into the sealing system meet the standards in real time, and automatically record the collected data during the test process.
