Abstract
A kind of safety cut-off valve replacement and fixation mechanism is the utility model is related to, including：Ratchet and pawl arrangement, ratchet is arranged on pawl base, pawl base is arranged on fixed case, torsionspring is fixed on fixed case and ratchet, ratchet is arranged on gear shaft, gear shaft, fixed case and shield are installed on safety cut-off valve body, during normal work, rotate gear shaft, rotating plate shaft is driven to rotate by driving gear set, ratchet is blocked by ratchet, prevent rotating plate shaft from driving turnover panel reversion to close valve, ensure that turnover panel is in open position, during abnormal work, the downward shock bar of pilot valve weight, ratchet is set to depart from ratchet, out of control turnover panel can automatically revert to closed position.Beneficial effect is：Simple in construction using click, processing cost is low, is easy for installation and maintenance, and because of vibrations turnover panel will not be made to break off relations, and stability is good, long lifespan, and ratchet and pawl can all block automatically after rotating very little angle, and laborsaving and security is good, will not be hurted sb.'s feelings because handwheel inverts.
Description
Technical field
It the utility model is related to a kind of valve reset fixed mechanism, more particularly to a kind of safety cut-off valve replacement and fixation machine
Structure, belong to safety cut-off valve.
Background technology
Safety shut-off valves replacement and fixation mechanism is the mechanism for controlling safety cut-off valve normally-open, ensures safety cut-off valve
In normal work, valve will not close automatically.
The replacement and fixation mechanism majority of safety cut-off valve is to use hook and support block form at present, i.e., in turnover panel branch
One hook to be installed on frame, a hook or support block are installed on valve body, during replacement and fixation, two hooks link together,
Or a hook is ridden in support block.It is disadvantageous in that：1st, between linking up with and link up with or the angle between support block will close
It is suitable, self-locking or automatic disengagement not so can be formed, after forming self-locking, even if by external force collision, two hooks are also difficult to be disengaged, therefore is turned over
Plate can not return to closed position, and safety cut-off valve can not cut off source of the gas, cause potential safety hazard；If often automatic disengage, pacify
Full stop valve can often cut off source of the gas, make it can not normal work.2nd, requirement on machining accuracy is high, if precision is low to cause two
Part frictional force increases, and the result of frictional force increase is identical with the result of self-locking.Above-mentioned 2 points can make processed complex, and cost increases
Height, and above two structure is mounted in safety cut-off valve inner, it is necessary to which opening safety cut-off valve body could install and tie up
Repair, be not easy installation and maintenance, it is very inconvenient.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, in view of the above-mentioned problems, providing one kind uses ratchet
With ratchet pawl reset fixed mechanism.
The utility model to achieve the above object, using following technical scheme：It the utility model is related to a kind of safety cut-off
Valve replacement and fixation mechanism, including：Fixed case, ratchet, gear shaft, ratchet, pawl base, guide sleeve, trip rod, weight, pawl axis,
Torsionspring, fixed seat, driving gear set, rotating plate shaft, shield.Ratchet is arranged on pawl base, and pawl base is arranged on fixed case
On, torsionspring is fixed on fixed case and ratchet, and ratchet is arranged on gear shaft, and gear shaft is driven by driving gear set and turned over
Plate is rotated, and gear shaft, fixed case and shield are installed on safety cut-off valve body, and weight, guide sleeve are arranged on shield, are hit
Bar is arranged in guide sleeve, during normal work, rotates gear shaft, drives rotating plate shaft to rotate by driving gear set, by ratchet card
Firmly ratchet, prevent rotating plate shaft from driving turnover panel reversion to close valve, ensure that turnover panel is in open position, during abnormal work, pilot valve
The downward shock bar of weight forces ratchet to be rotated around pawl axis, departs from ratchet, and out of control turnover panel can automatically revert to
Closed position.
Beneficial effect is：Simple in construction using click, processing cost is low, is easy for installation and maintenance, will not be because of vibrations
And turnover panel is broken off relations, stability is good, long lifespan, and ratchet and pawl can all block automatically after rotating very little angle, laborsaving and safe
Property it is good, will not because handwheel invert hurt sb.'s feelings.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is that safety cut-off valve resetting-mechanism is arranged on front view on valve.
Fig. 2 is that safety cut-off valve resetting-mechanism is arranged on left view on valve.
Fig. 3 is safety cut-off valve resetting-mechanism A-A figures.
In figure：75. fixed case, 76. gear shafts, 77. ratchets, 78. ratchets, 79. pawl bases, 80. guide sleeves, 81. hit
Bar, 82. weights, 83. pawl axis, 84. torsionsprings, 85. fixed seats, 86. driving gear sets, 87. rotating plate shafts, 88. shields,
100. safety cut-off valve, 101. turnover panels.
Embodiment
