Problems solved by technology

[0005] In order to solve the problem that the existing pneumatic valve gas supply method cannot satisfy the problem of high reliable gas supply within the limited time of the launching process, the present invention innovatively proposes a remote control online redundant gas supply path and The air supply method is to work through two pressure reducers at the same time. If any pressure reducer fails, the control process does not need to be changed or switched, and the other line continues to work. Even if the two pressure reducers fail, it can still The gas supply is maintained through the gas storage tank until the launch task is completed. Therefore, the present invention is a high-reliability, hot-backup online redundant design gas supply method

Embodiment 1

[0033] like figure 1 As shown in the figure, the present invention discloses a remote-controlled online redundant air supply circuit for ensuring a plurality of pneumatic valves. There is an air source cut-off valve JF0 on the pipeline connecting the air inlet end of the air pipe with the air source. Air supply can be realized by manually opening the air source cut-off valve JF0, and a filter is set on the pipeline between the air source and the air source cut-off valve JF0. The device G1 is used to filter excess matter. In this embodiment, the gas source is a nitrogen gas source, and the gas collecting pipe is arranged in a circular structure as a whole to play a role of voltage stabilization. Three pressure gauges P0; the gas collecting pipe has a first gas outlet end and a second gas outlet end, the gas storage tank has a first gas inlet end and a second gas inlet end, and the first gas outlet end and the first gas inlet end pass through the first gas The second gas outlet...

Embodiment 2

[0038] like figure 1 , 2 As shown, based on the same inventive concept as the first embodiment, the present embodiment discloses a remote-controlled online redundant gas supply method for ensuring multiple pneumatic valves by utilizing the above-mentioned gas supply gas path. The gas method includes the following steps:

[0039] Step 1. Before the personnel are evacuated, manually open the gas source shut-off valve JF0, then the high-pressure nitrogen gas passes through the filter G1 to achieve the purpose of making the gas in the gas source enter the gas collecting pipe. The gas source pressure displayed on the third pressure gauge P0 is p0 .

[0040] Step 2, adjust the first pressure reducer JQ1 and the second pressure reducer JQ2 respectively, and make the air pressure at the outlet of the two pressure reducers be the upper limit P of the working pressure of the pneumatic valve. 上 , the air pressure displayed on the first pressure gauge P1 is p1, the air pressure display...

Abstract

The invention discloses a gas-supply gas circuit and method guaranteeing remote control online redundancy of multiple pneumatic valves. The gas-supply gas circuit comprises a gas collecting pipe, twogas channels and a gas storage tank; the gas collecting pipe and the gas storage tank are connected by the two gas circuits, and the two gas circuits are provided with a relief valve, a safety valve and a one-way valve respectively; the gas storage tank is connected to the pneumatic valve; the gas supply method comprises the following steps: a gas source check valve is opened, two pressure reducers are adjusted respectively, two electric check valves are opened by remote control, and when the pressure reducer on one gas circuit fails, normal gas supply is realized by online redundancy hot backup of the other gas circuit. When the two pressure reducers both fail, the gas use demand of the multiple pneumatic valves is guaranteed by gas stored in the gas storage tank. The gas supply reliability is improved, no any change and action switching are required in the back end control flow when the pressure reducers have a fault, the emission flow is not effected, and the risk that the staff goto the front end to deal with the emergency and remove the faults is also reduced.

Description

technical field [0001] The invention relates to the technical field of pneumatic valve air supply, and more specifically, the invention relates to an air supply air path and method for ensuring remote control online redundancy of a plurality of pneumatic valves. Background technique [0002] At present, most of the launch of large launch vehicles and space shuttles adopts unattended remote control. A few hours before the launch of large launch vehicles and space shuttles, personnel are evacuated from the site, in order to minimize or even avoid possible damage to personnel and equipment. The damage of the equipment puts forward higher requirements on the reliability of the equipment and the operation of the remote control equipment. [0003] It is worth mentioning that there are many gas-using projects at the space launch site. It is necessary to decompress the high-pressure gas provided by the gas source into a low-pressure gas, and then supply the pneumatic valve to realiz...
