Abstract
The invention discloses a fire hydrant valve lock, and belongs to the field of pipeline equipment. The fire hydrant valve lock is composed of an opener (1) and a lock body. The lock body is mainly composed of an outer transmission sleeve (3), a transmission block (4) and a spring (5). The opener (1) is internally provided with a magnetic steel (2) and an emergency pin inserting hole (14), and the opener (1) and the outer transmission sleeve (3) are in matched transmission; the transmission block (4) and the spring (5) are arranged in the outer transmission sleeve (3), and the transmission block (4) and the outer transmission sleeve (3) are in matched transmission; the lower end of the outer transmission sleeve (3) is connected with an outer shell of a valve rod (8) through a positioning pin; magnetic steel (2) is arranged in the transmission block (4), and the polarity of the magnetic steel in the transmission block (4) is repellent to the polarity of the magnetic steel (2) of the opener (1); when the spring (5) is in the compressed state, the transmission block (4) is matched with the valve rod (8); when the spring is in the extending state, the transmission block (4) and the valve rod (8) are separated; and the opener (1) is additionally provided with an emergency pin (9) in a matched manner. The fire hydrant valve lock is high in safety, not prone to being stolen away and capable of being emergently unlocked.
Description
Technical field
The invention belongs to field of pipeline equipment, be specifically related to a kind of hydrant valve door lock.
Background technique
Everybody is able to turn on or off for the valve of current common fire hydrant, causes someone and utilizes fire hydrant to change use matter, steal fire-fighting water, even destroy fire fighting device.Bring great economic loss and potential safety hazard to thus water undertaking and fire department.And lock on fire hydrant valve, once unblank to break down, then fire hydrant valve of not opening, stamps out a fire impact.
Summary of the invention
When the object of the invention is to overcome existing fire hydrant valve without lock, fire-fighting water is easily stolen, when fire hydrant valve has a lock, the defect stamped out a fire will be affected once break down, for people provide a kind of Security high, not easily pirate of the open, again can the hydrant valve door lock of emergency opening.
The object of the invention is to be achieved through the following technical solutions:
Hydrant valve door lock of the present invention is made up of opener 1 and lock body, lock body is arranged on hydrant valve top, lock body forms primarily of outer drive sleeve 3, drive block 4 and spring 5, it is characterized in that being provided with magnet steel 2 and emergent pin jack 14 in opener 1, opener 1 coordinates transmission with outer drive sleeve 3; Be disposed with drive block 4 and spring 5 in outer drive sleeve 3 from top to bottom, drive block 4 coordinates transmission with outer drive sleeve 3, and outer drive sleeve 3 lower end is connected with valve rod 8 shell by locating stud 7; Magnet steel 2 is provided with, the magnet steel 2 in drive block 4 and magnet steel 2 polar repulsion of opener 1 in drive block 4; When spring 5 is in compressive state, drive block 4 coordinates with valve rod 8, and when spring 5 is in extended configuration, drive block 4 and valve rod 8 depart from; Opener 1 is separately furnished with emergent pin 9.
Working procedure of the present invention:
With the external drive sleeve pressure of the opener with the corresponding magnet steel of multiple spot, multiple spot magnet steel on opener and the multiple spot magnet steel polar repulsion on drive block, thus promote drive block overcome spring elastic force slide downward, drive block is just engaged valve rod, after rotating opener, move drive block by outer transmission cuff, just can be with ovable valve stem, thus open and close fire hydrant.After taking off opener, the magnet steel on drive block just loses the repulsive force of the magnet steel on opener, and spring also just rebounds and promotes drive block rising, drive block is made to depart from the occlusion of valve rod, so just how to rotate outer drive sleeve, be also idle running, can not fire hydrant be opened and closed.Thus achieve and could open and close fire hydrant with special tool, and otherwise just can only dally, cannot fire hydrant be opened and closed.
Extremely special, in unexpected situation, hydrant valve door lock is because of magnet steel loss of excitation or other reason cisco unity malfunction, the emergent pin carried with opener is put into the emergent pin jack of opener, opener is pressed in outer transmission put, extracts the plate rod of opener out, firmly knock opener, emergent pin is made to wear out outer drive sleeve, prop up screwdown driving block, overcome the elastic force of spring, allow drive block be engaged valve rod, rotate opener again, fire hydrant just can open and close.
Driving mechanism of the present invention adopts and is flexibly connected, and effectively can prevent artificial destruction, could must open and close with special special tool, and the imitated living instrument of profile then can only dally and can not open and close, and has effectively stopped the generation of pirate of the open event.The present invention also has special emergent protective measures, can open hydrant valve door lock quickly and easily in extremely special, unexpected situation, thus the keying not affecting fire hydrant uses.
Hydrant valve door lock of the present invention also can be used for other pipeline valve.
Therefore, when instant invention overcomes existing fire hydrant valve without lock, fire-fighting water is easily stolen, and when fire hydrant valve has a lock, will affect the defect stamped out a fire once break down, the hydrant valve door lock Security provided is high, and not easily pirate of the open again can emergency opening.
