Description
Technical field
The invention belongs to field of pipeline equipment, and in particular to a kind of hydrant valve door lock.
Background technology
Everybody is able to turn on or off for the valve of current common fire hydrant, causes someone and utilizes fire hydrant change aqueous nature, steals
Fire demand water, or even destroy fire fighting device.Thus great economic loss and safety are brought to water undertaking and fire department
Hidden danger.And locked on fire hydrant valve, broken down once unlocking, then fire hydrant valve of not opening, will influence to stamp out a fire.
The content of the invention
During it is an object of the invention to overcome existing fire hydrant valve without lock, fire demand water is easily tampered, fire hydrant valve
When having lock, once break down by influence stamp out a fire, for people provide one kind it is safe, be not easy pirate of the open, and can
The hydrant valve door lock of emergency opening.
The purpose of the present invention is achieved through the following technical solutions：
The hydrant valve door lock of the present invention is made up of opener 1 and lock body, and lock body is arranged on hydrant valve top, lock body
Mainly it is made up of outer drive sleeve 3, drive block 4 and spring 5, it is characterised in that magnet steel 2 is provided with opener 1 and emergent pin is inserted
Hole 14, opener 1 coordinates with outer drive sleeve 3 to be driven；Drive block 4 and spring are disposed with from top to bottom in outer drive sleeve 3
5, drive block 4 coordinates with outer drive sleeve 3 to be driven, and the outer lower end of drive sleeve 3 passes through alignment pin 7 and the cage connection of valve rod 8；Drive block 4
Inside it is provided with magnet steel 2, the polar repulsion of magnet steel 2 of the magnet steel 2 in drive block 4 and opener 1；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 departs from valve rod 8；Opener 1 is separately equipped with emergent
Pin 9.
The course of work of the present invention：
Depressed with the external drive sleeve of opener with the corresponding magnet steel of multiple spot, the multiple spot magnet steel on opener is with passing
Multiple spot magnet steel polar repulsion on motion block, so as to promote drive block to overcome the elastic force slide downward of spring, drive block is just engaged
Valve rod, after rotating opener, drive block is moved by outer transmission cuff, just energy band ovable valve stem, so as to open and close fire hydrant.When removing
After opener, the magnet steel on drive block just loses the repulsive force of the magnet steel on opener, and spring also just rebounds and promoted
Drive block rises, and drive block is departed from the occlusion of valve rod, thus how to rotate outer drive sleeve, and idle running, it is impossible to which keying disappears
Anti- bolt.It it is achieved thereby that fire hydrant could be opened and closed with specific purpose tool, and otherwise can only just dally, fire hydrant can not be opened and closed
.
Extremely special, in the case of unexpected, hydrant valve door lock because of magnet steel loss of excitation or other reason cisco unity malfunctions,
The emergent pin carried with opener is put into the emergent pin jack of opener, opener, which is pressed in outer transmission, to be put,
Extract the plate rod of opener out, firmly tap opener, emergent pin is worn out outer drive sleeve, prop up screwdown driving block, overcome
The elastic force of spring, allow drive block to be engaged valve rod, be rotated further by opener, fire hydrant is with regard to that can open and close.
The transmission mechanism of the present invention can effectively prevent artificial destruction using being flexibly connected, must be with special specific purpose tool
It can open and close, and the instrument of imitated profile striking resemblances can only then dally and can not open and close, and effectively prevent the hair of pirate of the open event
It is raw.The present invention also has special emergent safeguard procedures, and fire hydrant can be quickly and easily opened in the case of extremely special, unexpected
Valve lock, used so as to not influence the keying of fire hydrant.
The hydrant valve door lock of the present invention can also be used for other pipeline valves.
Therefore, during instant invention overcomes existing fire hydrant valve without lock, fire demand water is easily tampered, and fire hydrant valve has lock
When, once break down by influence stamp out a fire the defects of, there is provided hydrant valve door lock it is safe, be not easy pirate of the open, and can
Emergency opening.
