Problems solved by technology

Therefore, there are generally the following defects: 1) Due to certain uncertain factors, such as large gas leakage, fire, earthquake and other unsafe conditions, personnel cannot manually cut off the scene manually, and the cut-off control cannot be realized when they want to cut off remotely
2) There is no program control, and remote intelligent control cannot be realized. Personnel must be arranged on site, which consumes a lot of manpower and material resources, resulting in an increase in operating costs. At the same time, due to the influence of human factors, the reliability and monitoring of operations are poor.

Embodiment 1

[0019] Such as figure 2 As shown, the cut-off valve is respectively connected with a manual cut-off device, a pneumatic automatic cut-off device 12 and an electromagnetic remote control mechanism.

[0020] Wherein the connection relationship between the manual cut-off device and the pneumatic automatic cut-off device 12 and the cut-off valve is the same as that of the prior art, one end of the lever 10 is articulated with the bracket 9, and the other end of the lever 10 is fixedly connected with the cut-off rod 14 of the pneumatic automatic cut-off device 12 , the middle part of the lever 10 is connected with a positioning rod 11, the position of the lever 10 is fixed by the positioning rod 11, and the positioning rod 11 also functions as a rotating shaft in the middle of the lever 10.

[0021] After the gas enters from the air inlet 13 at the bottom of the pneumatic automatic cut-off device 12, once overpressure or underpressure occurs, the cut-off rod 14 of the pneumatic au...

Embodiment 2

[0027] The explosion-proof electromagnet 2 is fixedly connected with a support 1 by bolts, and the support 1 is also fixedly connected with the shut-off valve body, so that the explosion-proof electromagnet 2 is firmly fixed on the outside of the shut-off valve body.

[0028] The opening of the explosion-proof electromagnet 2 with the armature 4 is fixedly connected with an anti-loosening nut 6, the anti-loosening nut 6 can limit the position of the armature 4, so that it can only move towards the inner core direction of the opening of the explosion-proof electromagnet 2, preventing the armature from 4 falls off after moving outward.

Abstract

The invention relates to an electromagnetic remote control mechanism for a gas cut-off valve. The electromagnetic remote control mechanism at least comprises an anti-explosion electromagnet, a power interface, an armature, a linking rod and a supervisory control and data acquisition (SCADA) system, wherein the power interface of the anti-explosion electromagnet is connected with the SCADA system by a power line; the armature is arranged at a side opening of the anti-explosion electromagnet; the armature is movably connected with one end of the linking rod; and the other end of the linking rod is movably connected with the bottom of a lever of a shut-off valve. The electromagnetic remote control mechanism for the gas cut-off valve has the advantages that the electromagnetic remote control mechanism is further fixedly connected at the bottom of the lever; when gas needs to be cut off remotely, the SCADA system can control the anti-explosion electromagnet to attract the armature remotely, the armature drives the linking rod to translate, the linking rod pulls the lever to rotate around a locating rod clockwise; at the moment, a bracket breaks off the top end of the lever to implement the remote control cut-off of the cut-off valve.

Description

technical field [0001] The invention relates to the field of gas transmission and distribution, in particular to an electromagnetic remote control mechanism for a gas cut-off valve in a gas transmission and distribution system. Background technique [0002] The gas transmission and distribution system is similar to the power transmission and distribution system, and its circuit is also equipped with safety devices, such as relief valves and shut-off valves. [0003] When the inlet air pressure at the front end of the regulator fluctuates sharply or other factors cause the pressure in the downstream pipeline at the rear end of the regulator to rise sharply and exceed the safety upper limit set by the shut-off valve, the shut-off valve will automatically cut off in an emergency, and the rear end of the shut-off valve will be disconnected. Gas supply, safety protection for downstream gas equipment. Therefore, the shut-off valve is an indispensable part of the gas transmission ...
