Remote control system of long-distance pipeline block valve chamber

Abstract

The invention discloses a remote control system of a long-distance pipeline block valve chamber, and the remote control system comprises a driving system, a remote control and transmission system, an upper operation center and a solar energy power supply system, wherein the driving system comprises an execution mechanism connected with a valve rod of a block valve, a 24V direct current electric head used for driving the execution mechanism to open or close the block valve, and a control cabinet; the remote control and transmission system comprises a remote measurement and control terminal which is used for remotely controlling the control cabinet and realizing the real-time transmission of long-distance pipeline pressure data and temperature data; the upper operation center is mutually communicated with the remote measurement and control terminal and realizes the remote control over the block valve through transmitting control instructions to the remote measurement and control terminal; and the solar energy power supply system supplies power for the execution mechanism and each instrument unit. A 24V large-power weak current driving mode is adopted for the execution mechanism, remote control of a big-caliber high-pressure crude oil or other medium long-distance pipeline block valve chamber without mains power support and without optical cable concomitance is realized, line patrol workload of workers is reduced, and loss and impact on the environment possibly caused at a pipeline failure state are reduced.

Description

technical field [0001] The present invention relates to the remote control of the cut-off valve in the pipeline, more specifically, relates to a remote control system for the cut-off valve chamber of the long-distance crude oil pipeline, which is used for large-diameter and high-pressure crude oil without mains support and without optical cable accompanying The remote control of the cut-off valve chamber of the long-distance pipeline can also be used for the remote control of the cut-off valve chamber of the remote area of ​​the large-diameter long-distance pipeline for transporting other media. Background technique [0002] When long-distance pipelines transport crude oil or refined oil, a certain number of shut-off valve chambers will be set along the way according to the regulations to ensure that the pipelines are shut off during maintenance and emergency rescue, and to a certain extent reduce the possible losses and environmental pollution caused by accidents. The shut-...

Problems solved by technology

[0008] Disadvantages of the existing cut-off valve control: the first and second configurations cannot realize the remote control of the valve, and cannot realize the shut-off of the valve at the first time of the accident, so as to reduce the economic loss and possible damage to the environment to a minimum Smallest, workers need to patrol the line frequently, labor intensity is high, and the number of workers is large

The third configuration can only be equipped in a very small number of valve rooms with good conditions, and most of the valve rooms are located in remote places, without mains power and optical cable support, so it is difficult to realize remote control and video monitoring of the valve room
