Description
Technical field
The present invention relates to a kind of valve reset fixed mechanism more particularly to a kind of safety cut-off valve replacement and fixation mechanisms, belong to
In safety cut-off valve.
Background technology
Safety shut-off valves replacement and fixation mechanism is to control the normally-open mechanism of safety cut-off valve, ensures safety cut-off valve
In normal work, valve will not be automatically closed.
The replacement and fixation mechanism majority of safety cut-off valve is to use hook and supporting block form at present, i.e., in turnover panel branch
One hook to be installed on frame, a hook or supporting block are installed on valve body, when replacement and fixation, two hooks link together,
Or a hook rides in supporting block.It is disadvantageous in that：1, between linking up with and link up with or the angle between supporting block will close
It is suitable, self-locking or automatic disengagement not so can be formed, after forming self-locking, even if being disengaged by difficult if two hooks of external force collision, therefore is turned over
Plate cannot return to closed position, and safety cut-off valve cannot cut off air source, cause security risk；If often automatic disengage, pacify
Full stop valve can often cut off air source, it is made to can not work normally.2, requirement on machining accuracy is high, if precision is low to cause two
Part frictional force increases, and the increased result of frictional force is identical with the result of self-locking.Above-mentioned 2 points can make processing complicated, and cost increases
Height, and above two structure is mounted in safety cut-off valve inner, needs opening safety cut-off valve body that could install and tie up
It repaiies, is not easy installation and maintenance, it is very inconvenient.
Invention content
It is an object of the invention to overcome the shortcomings of above-mentioned technology, in view of the above-mentioned problems, providing a kind of using ratchet and spine
Pawl replacement and fixation mechanism.
The present invention to achieve the above object, using following technical scheme：The present invention relates to a kind of safety cut-off valves to reset admittedly
Determine mechanism, including：Fixed case, ratchet, gear shaft, pawl, pawl base, guide sleeve, trip rod, weight, pawl axis, torsion bullet
Spring, fixed seat, driving gear set, rotating plate shaft, shield.Pawl is mounted on pawl base, and pawl base is mounted on fixed case, torsion
Spring is fixed on fixed case and pawl, and ratchet is mounted on gear shaft, and gear shaft drives turnover panel to rotate by driving gear set,
Gear shaft, fixed case and shield are installed on safety cut-off valve body, and weight, guide sleeve are mounted on shield, trip rod installation
In guide sleeve, when normal work, gear shaft is rotated, rotating plate shaft rotation is driven by driving gear set, ratchet is blocked by pawl,
It prevents rotating plate shaft from turnover panel reversion being driven to close valve, ensures that turnover panel is in open position, when abnormal work, pilot valve weight is downward
Shock bar forces pawl to be rotated around pawl axis, is detached from ratchet, and out of control turnover panel can automatically revert to closed position.
Advantageous effect is：Simple in structure using click, processing cost is low, is easy for installation and maintenance, will not be because of vibrations
And turnover panel is made to break off relations, stability is good, long lifespan, and ratchet and pawl can all block automatically after rotating very little angle, laborsaving and safe
Property is good, will not hurt sb.'s feelings because handwheel inverts.
