Abstract

The invention discloses a rotary sliding disc type pressure electronic scanning valve. The rotary sliding disc type pressure electronic scanning valve comprises an installation support internally provided with a hollow cavity, a rotary driving piece arranged in the hollow cavity, a rotary disc driven by the rotary driving piece to be switched between a first position state and a second position state in a rotary mode, a front end cover wrapping the rotary disc, and a plurality of pressure sensor assemblies annularly embedded in the installation support. A plurality of first air guide needle tubes and second air guide needle tubes are arranged on the front end cover; first sets of channels communicating with the pressure sensor assemblies in a one-to-one correspondence mode are arranged inthe installation support, and second sets of channels for communicating the first air guide needle tubes with the first sets of channels in a one-to-one correspondence mode and third sets of channelsfor communicating all the first sets of channels and communicating with the second air guide needle tubes are arranged in the rotary disc. Thus, automatic switching between a pressure detection stateand a sensor calibration state can be realized, online automatic calibration is realized, and the accuracy and reliability of pressure detection are greatly improved.

Description

【Technical field】

[0001] The invention belongs to the technical field of pressure detection, in particular to a rotary sliding disc pressure electronic scanning valve. 【Background technique】

[0002] The pressure scanning valve is a kind of multi-channel pressure scanning measurement equipment. It is an intelligent sensing device used to realize real-time measurement of multi-channel pressure signals. It is widely used in wind tunnel, impeller, engine, and propulsion track tests. At present, the commonly used pressure scanning valves or similar products are mostly 16-channel pressure data measurement, and there are generally disadvantages such as large product size, many accessories, inconvenient installation, and slow scanning speed. It is urgent to develop a highly integrated, miniaturized, scanning valve. Fast and manometrically accurate pressure scanning measurement device.

[0003] In the prior art, CN201920362403.9 is a multi-channel pressure scanning measurement and ...
