Abstract

The flameout explosion preventer for pipeline of the utility model belongs to the safety equipment of pipelines mainly used in mining, which comprises a signal detection mechanism and a machine actuator. The signal detection mechanism is composed of a temperature sensing probe, a smoke sensing probe, a temperature transmitter, a smoke sensing transmitter, a temperature control switch, a smoke sensing control switch and power line, while the machine actuator is composed of an electromagnet, a magnetic receiver, a lever, a lever bracket, a spring, an anchor gate crank, an anchor gate, an anchor gate shaft, a shaft bearing, a bearing seat and a housing. When detecting a danger signal, the signal detection mechanism cuts off the electric source to make the electromagnet disgauss, and the anchor gate which is normally open in the housing immediately closes to prevent danger spreading. The utility model is characterized in that the utility model is versatile and reliable to blockade not only flame but also the spread of spark, high temperature, harmful gas and material.

Description

Pipeline cutoff explosion-proof device

Affiliated technical field

The utility model relates to the pipe safety device.

Technical background

Being useful on the safety installations that prevents inflammable, explosive, harmful gas or the material conveying pipe generation condition of a fire and spread is flame trap, as corrugated sheet flame arrester for pipe, labyrinth flame arrester for pipe etc., their back-fire relief principle all is by tortuous narrow slit or aperture aisle limit or eliminates combustion condition and stop flame to spread in pipeline, there is following drawback in they: the one, and function singleness, only flame of combustion is played retardation, and spark, high temperature and harmful gas or material still can pass through, and safety is unreliable; The 2nd, resistance greatly, easily stop up, be unfavorable for the conveying of gas or material, it is unreliable to work.

Summary of the invention

The purpose of this utility model be to provide a kind of safe, work is all reliable, the pipeline cutoff explosion-proof device that both prevented fires also anti-high temperature, harmful gas or material spread in pipeline.

The utility model adopts following manner to achieve the goal: this device is made up of input mechanism and mechanical actuating mechanism, feeler mechanism is popped one's head in by the temperature sense, cigarette sense probe, temperature transmitter, cigarette sense transmitter, temp control switch, cigarette sense control switch and power line are formed, mechanical actuating mechanism is by electromagnet, magnetic receiver, lever, lever dolly, spring, the gate crank, gate, the gate axle, bearing and bearing support thereof and housing are formed, when input mechanism detects the dangerous situation signal, cut off the electricity supply, magnet loses magnetic force, and the gate of the interior normal open form attitude of housing is promptly closed and stoped dangerous situation to spread.

Characteristics of the present utility model: the one, multi-functional, outside the decapacitation blocking-up flame, also block spreading of spark, high temperature and harmful gas or material, safe and reliable; The 2nd, in pipeline when work,, gate is opened, and does not have resistance, does not stop up, gas or mass transport is smooth and easy, reliable operation.

Below in conjunction with accompanying drawing embodiment is described:

Description of drawings

Accompanying drawing cuts open the main schematic representation of looking for this general ability.

Specific embodiments

With reference to accompanying drawing, this device is made up of input mechanism and mechanical actuating mechanism, input mechanism is made up of temp probe (1), cigarette sense probe (2), temperature transmitter (3), cigarette sense transmitter (4), temp control switch (5), cigarette sense control switch (6) and power line, and temp probe (1) and cigarette sense probe (2) are positioned in the pipeline of easy generation dangerous situation; Mechanical actuating mechanism is by electromagnet (8), magnetic receiver (9), spring (10), stiffening plate (11,17), lever dolly (12), lever (13), gate crank (14), gate axle (15), bearing and bearing support thereof (16), gate (18), housing (19) and retaining frame (20) are formed, housing (19) is a square tube shape, there is flange head at two ends, be serially connected in the pipeline, gate (18) and retaining frame (20) are arranged in the housing (19), gate (18) is a square plate, the right welding gate axle (15), gate axle (15) both sides external part pass bearing (16) outer end and the welding of gate crank (14) lower end; The gate crank is a U-shaped, and upper cross bar is stuck on lever (13) the left end breach, and lever (13) is hinged on the U-shaped lever dolly (12), and lever (13) right-hand member connects spring (10) upper end, and the magnet (8) that is positioned on the U magnet seat (9) is arranged above the lever right part.
