Embodiment 1

[0042] Such as figure 2 As shown, the remote monitoring and alarm control system of the pipeline interception device includes the wellhead safety hydraulic interception device 1, and also includes a remote actuator 2. The remote actuator 2 is connected with the hydraulic control system 13 of the wellhead safety hydraulic interception device 1 to control the The high-pressure hydraulic oil in the hydraulic control system 13 returns to the oil storage tank 12 to realize the closing of the hydraulic shutoff valve 11.

[0043] The pipeline interception remote monitoring alarm control system of this embodiment is connected with the hydraulic control system 13 of the wellhead safety hydraulic interception device 1 by setting the remote actuator 2 to remotely control the flow of hydraulic oil in the hydraulic control system 13 to force the high-pressure hydraulic pressure in it. The oil returns to the storage tank 12, and the hydraulic cut-off valve 11 loses the support of the high-pres...

Embodiment 2

[0048] Such as image 3 As shown, the pipeline cut-off remote monitoring alarm control system of this embodiment has the same structure as that of Embodiment 1, except that: the control valve 21 is detachably provided with a device for controlling the opening and / or closing of the control valve 21 Manual switch 23.

[0049] In the remote monitoring and alarm control system for pipeline interception of this embodiment, a manual switch is set on the control valve 21 as the valve control mechanism 22, so that when the valve control mechanism 22 fails, the control valve 21 can be manually opened to realize the hydraulic shutoff valve 11. Manual remote cutoff ensures timely cutoff of the cutoff valve.

[0050] Preferably, the manual switch 23 is detachably connected to the control valve 21. Due to the detachable connection of the manual switch 23 and the control valve 21, it is possible to choose whether to install the manual switch 23 according to the actual situation of the site, so ...

Embodiment 3

[0052] Such as Figure 4-5 As shown, the pipeline interception remote monitoring alarm control system of this embodiment has the same structure as that of Embodiment 2, except that it also includes an alarm device 4, which includes an audible and visual alarm module and / or a voice broadcast module. The alarm device 4 is in communication connection with the valve control mechanism 22.

[0053] In the pipeline interception remote monitoring and alarm control system of this embodiment, the alarm device 4 is provided to notify the staff through the alarm sound and / or flashing and / or voice broadcast in time, so that the staff can accurately know the position of the interception valve in time and Carry out the corresponding treatment to reduce the accident handling time and avoid losses.

[0054] Preferably, it further includes a power supply device 3 that includes a solar panel 31 and a power storage device 32, and the power storage device 32 is electrically connected to the alarm devi...

Abstract

The invention relates to a safety protection facility for a mining and transportation pipeline, in particular to a remote monitoring alarm control system of a pipeline cutoff device. The remote monitoring alarm control system of the pipeline cutoff device comprises a wellhead safety hydraulic cutoff device and a remote executing mechanism, wherein the remote executing mechanism communicates with ahydraulic control system of a wellhead safety hydraulic cutoff device, the flow of hydraulic oil in the hydraulic control system is remotely controlled, high-pressure hydraulic oil in the hydraulic control system is forced to return to an oil storage tank, and a hydraulic cutoff valve loses supporting of the high-pressure hydraulic oil in the hydraulic control system. A flat gate valve forming the hydraulic cutoff valve is closed under the action of an internal spring of the flat gate valve, so that the cutoff of an air source is achieved, the structure is simpler and the closing is faster. According to the actual situation, the remote executing mechanism communicates with the wellhead safety hydraulic cutoff device arranged on the site through a hydraulic oil pipe, so that the distance between the remote executing mechanism and the wellhead safety hydraulic cutoff device is far, and the functions of remotely closing the hydraulic cutoff valve and cutting off the air source are achieved.

Description

Technical field [0001] The invention relates to safety protection facilities for mining and transportation pipelines, in particular to a remote monitoring alarm control system for a pipeline cutting device. Background technique [0002] The wellhead safety hydraulic interception device is an important safety protection facility at the well site. It is generally installed in the high-pressure pipeline of the natural gas production and transmission system, such as figure 1 As shown, the wellhead safety hydraulic cut-off device 1 mainly includes a hydraulic cut-off valve 11, a hydraulic control system 13, pipelines and connectors, etc. The hydraulic cut-off valve 11 is a combination of a hydraulic cylinder and a flat gate valve. When the set pressure is exceeded, the pressure of the station pipeline is lower than the set pressure due to rupture, leakage, or a fire alarm occurs, the hydraulic shut-off valve can be automatically closed through the high-pressure hydraulic oil stored in ...
