Abstract
The utility model belongs to an improvement on an explosion venting device of a metal rupture disc for a gas container, in particular to a state detection device for an arch-shaped metal rupture disc, which comprises an explosion venting valve on which the arch-shaped metal rupture disc is mounted, wherein the top of the body of the explosion venting valve is hinged with a lever bracket through a support, a turning plate made of light metal is fixedly connected with one end of the lever bracket, the turning plate is matched with the arch-shaped metal rupture disc that is mounted at the upper port of the explosion venting valve below the turning plate, one end part of a metal rod that is fixedly connected at one end of the lever bracket is matched with an approach switch, the approach switch is connected with a microcomputer monitoring system through a conducting wire, a balancing weight is arranged at the other end of the lever bracket, and the torque of the balancing weight is set such that the turning plate can be turned up by a gas flow leaked due to the rupture of the arch-shaped metal rupture disc. The state detection device for the arch-shaped metal rupture disc can detect the working states and the specific positions of the explosion venting valve and the arch-shaped metal rupture disc in time, and the rupture of the arch-shaped metal rupture disc for pressure relief can be found in time through the microcomputer monitoring system, so as to handle in time, prevent personal injury accidents and ensure safe production.
Description
Technical field
The utility model belongs to the improvement of the metallic rupture disk explosion venting device of poisonous, the flammable explosive gas container that is used for factory, particularly a kind of arch form metallic rupture disk condition checkout gear.
Background technique
The metallic rupture disk explosion venting device that is used for poisonous, inflammable, the explosion hazard gases container of factory, after the superpressure wave phenomenon occurring, microcomputer detecting system can't directly show the state of rupture disk, if untimely discovery fault, start urgent prediction scheme, gas medium diffuses, and just may cause security incidents such as burning, blast or gas poisoning.The arch form metallic rupture disk for playing crucial effect in safety and the production system, is the last line of defense that guarantees device security in gas burning system.With the blast furnace gas dry pulsed jet cloth filter is example, and explosion-released valve is installed in dust remover roof, and the arch form metallic rupture disk is attached to the front end of explosion-released valve.In the normal productive process, when pressure was elevated to the explosion-released valve bursting pressure in the deduster casing, the arch form metallic rupture disk at first broke, and pressure in the deduster casing is laid down, and the control accident occurs in the part, thereby guaranteed the safety of deduster equipment.Pressure release is difficult for reflecting intuitively but the arch form metallic rupture disk breaks, and grasp concrete in more dust catcher chamber is the explosion-released valve arch form metallic rupture disk explosion of which dust catcher chamber, misses an opportunity because of a delay, and causes a large amount of gas leakages, and accident is magnified.
Summary of the invention
The purpose of this utility model is to provide a kind of arch form metallic rupture disk condition checkout gear, can detect the working state and the particular location of explosion-released valve arch form metallic rupture disk timely and effectively, when metallic rupture disk explosion pressure release, can in time find by microcomputer detecting system, in time handle, the prevention personal injury accident guarantees safety in production.
The purpose of this utility model is achieved in that a kind of arch form metallic rupture disk condition checkout gear, comprise the explosion-released valve that the arch form metallic rupture disk is housed, the articulated lever bracket of bearing is passed through at top at the explosion-released valve valve body, one end of lever bracket affixed the turnover panel that constitutes by light metal, turnover panel matches with its below explosion-released valve arch form metallic rupture disk of installing of going up suitable for reading, and on this end lever bracket affixed metal rod ends with match near switch, connect microcomputer detecting system near switch by lead, the other end of lever bracket is installed with balancing weight, the size of balancing weight moment, with the arch form metallic rupture disk break the gas flow revealed can make turnover panel upwards upset be advisable.
After on poisonous, inflammable, the explosion hazard gases container of factory the utility model being installed when superpressure occurring, metallic rupture disk explosion on the explosion-released valve, the gas flow that leaks makes upwards upset of turnover panel, affixed metal rod ends cooperates with breaking away near switch on this end lever bracket, transmit signal to microcomputer detecting system near switch by lead, send alarm signal.Owing to directly show concrete explosion-released valve arch form metallic rupture disk explosion by microcomputer detecting system, in time start emergency preplan:
1, notifies squad leader, long, the coal anti-personnel of operation, wind direction evacuating personnel under the circular gas.
2, close this dust catcher chamber's casing coal gas, purified gas import and export butterfly valve and eyes valve immediately, open casing and diffuse, nitrogen purges.
3, the above colleague of three people, old rupture pressure disc is removed in the anti-monitoring of coal, and new rupture pressure disc is installed.
4, open this dust catcher chamber casing and import and export eyes valve, close casing and diffuse, open casing and import and export butterfly valve, close nitrogen and purge, casing comes into operation.
Find out that thus this model utility is to the generation of prevention personal injury accident and recover blast furnace rapidly and produce significant.
The utility model can detect the working state and the particular location of explosion-released valve arch form metallic rupture disk timely and effectively, when metallic rupture disk explosion pressure release, can in time find by microcomputer detecting system, in time handle, the prevention personal injury accident guarantees safety in production.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing,
Fig. 1 is a sectional structure schematic representation of the present utility model;
Fig. 2 is the plan structure schematic representation of Fig. 1.
Embodiment
A kind of arch form metallic rupture disk condition checkout gear, as Fig. 1, shown in Figure 2, comprise the explosion-released valve 1 that arch form metallic rupture disk 2 is housed, bearing 3 articulated lever brackets 4 are passed through at top at the explosion-released valve valve body, one end of lever bracket 4 affixed the turnover panel 5 that constitutes by light metal, turnover panel 5 matches with its below explosion-released valve 1 arch form metallic rupture disk 2 of installing of going up suitable for reading, and on this end lever bracket 4 affixed metallic rod 6 ends with match near switch 7, connect microcomputer detecting system near switch by lead, the other end of lever bracket 4 is installed with balancing weight 8, the size of balancing weight 8 moments, with arch form metallic rupture disk 2 break the gas flow revealed can make turnover panel 5 upwards upset be advisable.
