Abstract
The invention discloses an explosion-proof valve special for instrument wind; once the pipeline is broken and burst, the explosion-proof valve special for the first instrument wind before the burst point and the rupture point is automatically closed, so that the system pressure is effectively prevented from being reduced and the interlocking stop is realized due to the leakage of a large amount of media. After the explosion and the fracture point are repaired, the explosion-proof valve special for the instrument wind can be automatically in an open state (normal state) and can restore normal operation, the explosion-proof valve can be automatically cut off when a fault is finished without human intervention, and is provided with a balance pressure hole which can be automatically reset after the fault is restored; the invention has the beneficial effects that: the automatic switching-off device has the advantages of being capable of achieving automatic switching-off when a fault occurs without human intervention, automatically resetting after the fault is recovered, simple in structure, safe, reliable and easy to popularize and use.
Description
Technical field
The present invention relates to a kind of instrument wind special anti-explosion valve and processing thereof and using method.
Background technique
Instrument wind also claims to purify wind, that non-purification wind is through filtering, dry and obtained, non-purification wind is through dehydration, can be used as instrument wind after purification to use, instrument wind shows controlling mechanism in instrument and meter for automation as pneumatic valve, the air-source that flowmeter etc. use, instrument wind is specially for the instrumentation of modulating valve provides power, there is provided source of the gas both can to the instrument controlling and show process parameter, can be used for again to each production air valve as pneumatic valve, pneumatic fuel taps etc. provide power, its degree of purity requires higher, pressure stability, therefore in production process, instrument wind will often be opened.
And usually run into because other outer hydraulic pipings burst suddenly, disconnect in the industrial production, cause instrument wind line fracture to cause a large amount of instrument wind to outflow, instrument wind system pressure reduces interlocking action, causes system shutdown, causes very large economic loss to enterprise.
At present also there is no special protective gear to prevent because pipeline bursts suddenly, to disconnect and the instrument wind medium that causes leaks the generation of situation in a large number.
Generally speaking, the technical problem needing those skilled in the art urgently to solve at present is: how to manufacture an equipment and can prevent the medium in instrument wind from bursting suddenly at pipeline, leak in a large number when disconnecting.
Summary of the invention
Object of the present invention is exactly to solve the problem, and provides a kind of instrument wind special anti-explosion valve, and it has when not needing human intervention can complete fault and automatically cuts off, and automatically resets after fault recovery, and structure is simple, safe and reliable, is easy to the advantage promoted the use of.
To achieve these goals, the present invention adopts following technological scheme:
A kind of instrument wind special anti-explosion valve, mainly comprising valve body and spool, is spool import and outlet respectively about described valve body, and described spool inlet diameter is slightly less than valve core diameter, and described spool inlet diameter is greater than spool outlet diameter; Described spool there is balance pressure hole.
Described valve body becomes cylindrical, cube rod or multi-edge column-shaped.
Described spool becomes sphere-like.
Balance pressure hole on described spool is 1 or 2, is applied on spool.
Described instrument wind special anti-explosion valve with pipeline Placement is: flange, screw thread or weld.
A kind of processing method of instrument wind special anti-explosion valve is specific as follows:
Valve body once-through, valve core diameter is slightly larger than spool inlet diameter, and spool inlet diameter is greater than spool outlet diameter, and assembling type heats valve body, and carry out sub zero treatment to the spool of special anti-explosion valve, spool is provided with balance pressure hole.
Described assembling type is heated to be valve body and valve body is heated dilate, and loads spool.
A kind of using method of instrument wind special anti-explosion valve is specific as follows:
During normal operation, pressure reduction between spool inlet pressure and spool outlet pressure is not enough to promote valve core movement to closed condition, medium will pass through valve chamber, spool flows out, when pipeline after special valve once rupture, explosion, spool outlet pressure is in atmospheric pressure state, and spool inlet pressure is the same with manifold pressure, pressure reduction between such spool inlet pressure and spool outlet pressure increases suddenly, pressure reduction will promote valve core movement instantaneously to closed condition, close instrument wind special anti-explosion valve valve, the aperture only left on spool can flow through the medium of trace, after fault point is repaired, no longer closed state is formed to sky after instrument wind special anti-explosion valve valve, instrument wind carries out pressure balance by the balance pressure hole on spool, pressure reduction between spool inlet pressure and spool outlet pressure reduces gradually, when after spool inlet pressure and spool outlet pressure balance, spool returns to normal state under gravity.
Beneficial effect of the present invention:
1 can close explosion, front first the instrument wind special anti-explosion valve valve of point of rupture automatically, and effective Accident prevention expands.
2 are provided with balance pressure hole due to spool, automatically cut off, automatically reset after fault recovery when not needing human intervention can complete fault.
3 do not need to find and occur that pipeline bursts suddenly, front first valve of cut-off point is closed, and this valve can be closed instantaneously, avoids causing a large amount of medium to leak, enlargement loss; Prevent because system pressure reduces, cause system interlock to stop.
Accompanying drawing explanation
Fig. 1 is instrument wind special anti-explosion valve schematic diagram when normally working;
Schematic diagram when Fig. 2 is instrument wind special anti-explosion valve fault;
Wherein, 1 is valve body, and 2 is spool, and 3 is balance pressure hole, and P1 is spool inlet pressure, and P2 is spool outlet pressure, and P3 is normal pressure, and d1 is valve inlet diameter, and d2 is valve core diameter, and d3 is spool outlet diameter, and F1 is normal flow rate, reveals flow when F2 is fault.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As Fig. 1, a kind of instrument wind special anti-explosion valve, mainly comprises valve body 1 and spool 2, and described valve body about 1 is spool import and outlet respectively, and described spool inlet diameter d1 is slightly less than valve core diameter d2, and described spool inlet diameter d1 is greater than spool outlet diameter d3; Described spool 2 there is balance pressure hole 3.
Described valve body 1 one-tenth cylindrical or cube rod, multi-edge column-shaped.
Described spool 2 one-tenth sphere-like.
Balance pressure hole 3 on described spool 2 is 1 or 2, punches on spool 2.
Described instrument wind special anti-explosion valve with pipeline Placement is: flange, screw thread, weld.
A kind of processing method of instrument wind special anti-explosion valve is specific as follows:
Valve body 1 once-through, valve core diameter d2 is slightly larger than spool inlet diameter d1, and spool inlet diameter d1 is greater than spool outlet diameter d3, and assembling type heats valve body 1, and carry out sub zero treatment to the spool 2 of special anti-explosion valve, spool 2 is provided with balance pressure hole 3.
