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
The present invention relates to the gas transmission and distribution field, the electromagnetism telecontrol mechanism of fuel gas shutoff valve in particularly a kind of gas transmission and distribution system.
Background technique
Gas transmission and distribution system is similar with the electric power distributing system, also disposes safety installations in its loop, such as diffusing valve and cut-off valve.
When pressure governor front end inlet pressure fluctuation or other factors make pressure governor rear end downstream line internal pressure rise sharply; And when surpassing the upper safety limit value that cut-off valve sets; The cut-off valve automatic cutting in emergency breaks off cut-off valve rear end fuel gas supply, and the downstream gas-fired equipment is carried out safety protection.Therefore cut-off valve is a requisite constituent element in the gas transmission and distribution system.
In the existing gas industry, most for the cut-out control mode of cut-off valve is following two kinds: 1) on-site manual cuts off; 2) pneumatic superpressure (or under-voltage) is cut off automatically.Thereby ubiquity following defective: 1) because of certain uncertain factor, such as unsafe conditions such as combustion gas leakage in a large number, fire, earthquakes, personnel can not body face the scene and cut off manually, can't realize cutting off control when thinking long-range cut-out.2) do not have program control property, can't realize long-distance intelligent control, must the on-the-spot post of arrangement personnel, the manpower and materials of labor cause the increase of operating cost, and simultaneously owing to receive artificial factor, the reliability of operation and monitoring property etc. are relatively poor.
Summary of the invention
The objective of the invention is to above two point defects, overcome the deficiency of existing technology, a kind of fuel gas shutoff valve control device that can long-range Electromagnetic Control cuts off is provided.
The technological scheme that the present invention solves its technical problem employing is: a kind of electromagnetism telecontrol mechanism of fuel gas shutoff valve is characterized in: which comprises at least anti-explosion is electromagnetic iron, power interface, armature, linkage rod, Monitoring and Controlling and data processing system; The power interface of anti-explosion is electromagnetic iron is connected with Monitoring and Controlling and data processing system through power line, and the side mouth place of anti-explosion is electromagnetic iron is equipped with armature, and an end of armature and linkage rod flexibly connects, and the other end of linkage rod and the lever of cut-off valve bottom flexibly connect.
Built-in control knob of described Monitoring and Controlling and data processing system and PLC control circuit board.
Described Monitoring and Controlling and data processing system are arranged in the control room away from cut-off valve.
Be connected with bearing through bolt on the described anti-explosion is electromagnetic iron, bearing also is connected with the cut-off valve body-fixed.
The opening that described anti-explosion is electromagnetic iron is equipped with armature is fixedly connected with screwed retaining ring; Armature is in the inboard iron core of anti-explosion is electromagnetic iron and the position between the screwed retaining ring; Linkage rod is passed one side of screwed retaining ring and armature and is fixed, and the another side of armature is the inboard iron core of anti-electromagnet.
The bar hole on described lever bottom one side and linkage rod the right flexibly connects, and lever bottom opposite side connects with the cut-out bar of pneumatic automatic cut off device.
Described lever top and carriage articulate, and the lever middle part is connected with positioning rod.
The invention has the beneficial effects as follows owing to also be fixedly connected electromagnetism telecontrol of the present invention mechanism in the bottom of lever; When needing long-range cut-out combustion gas, Monitoring and Controlling and data processing system are that SCADA can attract armature by telecontrol anti-explosion is electromagnetic iron, and armature drives the linkage rod translation; The linkage rod pull lever turns clockwise around positioning rod; At this moment, carriage breaks away from from the lever top end, realizes the telecontrol of cut-off valve is cut off.
