Description
Technical field
The utility model is related to a kind of control unit, especially a kind of valve of locking device.
Background technology
Valve is the control unit in fluid media (medium) transport system, in fluid system, for controlling cutting for fluid media (medium)
It is disconnected with connection, direction, pressure, flow device；In industrial production environment, when maintenance personal overhauls equipment and pipeline
When, in order to ensure absolutely being closed with the equipment of valve control switch and pipeline, equipment and pipeline is made to be maintained at safe condition, or
In order to realize the keying of personal management's valve, limits other people and illegally open and close, be convenient for public utilities and community's estate management, make the energy
Allotment with convey planned progress, it is therefore desirable to the valve position of equipment and pipeline lock and listed warning, to accuse
Know other staff, workplace is being overhauled or use state, this valve must not operate without authorization, and machinery otherwise may occur and set
The release of standby accidental activation or the dangerous energy simultaneously causes damages, to ensure that maintenance personal will not be because of other in maintenance
The maloperation of personnel and lead to dangerous generation.
Existing valvular locking device is all fixed from activity adjustment, institute due to manufacturing scale error and lockhole
Cause locking inaccurate to be susceptible to two lockhole decentractions, the center spool of valve just, off-set phenomenon does not occur and leads
Valve is caused to have leakage phenomenon, for example it is particularly the case by Chinese utility model patent CN 201198920Y.
Utility model content
The utility model will solve the disadvantage that the above-mentioned prior art, provide it is a kind of can to the standard-sized sheet of valve or full off state into
Line-locked valve meets the demand of plant maintenance personnel safety.
The utility model solves the technical solution of its technical problem use：The valve of this locking device, including valve body
And runner, the spool that control runner opens and closes is installed on runner, is provided with the valve rod of movable valve plug rotation on valve body, it is solid on valve body
Surely there is upper cover, be fixed with longitudinally disposed positioning pin on upper lid, positioning pin is equipped with clamping block, opens that there are two opposite on clamping block
The first lockhole and single spliced eye being arranged, are arranged between two first lockholes and spliced eye in triangular shape, and clamping block passes through grafting
Hole is plugged at positioning pin and can rotate, and the top of valve rod is equipped with the shaft coupling of energy band ovable valve stem rotation, the foreign steamer of shaft coupling
Exterior feature is equipped with the handle that shaft coupling can be driven to rotate, and is fixed with extension board at the outer profile of shaft coupling, second is provided on extension board
Lockhole is provided with locating slot on shaft coupling, and positioning pin is located at locating slot, stops when shaft coupling rotates forward and stopped by positioning pin
When, valve be full-gear and manually drive clamping block rotation make side the first lockhole and the second lockhole position pairing, work as connection
Axis device rotates backward and stops that the when of stopping, valve are full off state and manually drive clamping block makes the first of the other side by positioning pin
Lockhole and the second lockhole position are matched.Here the effect of shaft coupling, positioning pin, clamping block, handle is, for valve wide open or entirely
Locking is carried out to valve when off status and ensure that equipment and the safe operation of pipeline maintenance personnel, also can avoid releasing for the dangerous energy
It puts and causes public safety hazards；Here the effect of locating slot is, can using locating slot come the full-gear of control valve or
Full off state or half-open position；Here shaft coupling is the shaft coupling block for connecting valve rod；When the first lockhole and the second lockhole match

It is useful for the transverse holes of lockset installation.Here the diameter of cylindrical bar is identical as the first lockhole, the second lockhole diameter, only coordinates
Tolerance is different, so after coordinating the first lockhole, the second lockhole using the cylindrical bar on fixed beam, shaft coupling and clamping block
Between there is no running clearance, to ensure that absolute positional relation of the spool in valve wide open or fully closed valve is motionless, avoid
Have running clearance between shaft coupling and clamping block and cause center spool not just, there is off-set phenomenon and valve caused to have leakage
Phenomenon occurs.
It is further perfect, the drawstring of high intensity is equipped between fixed beam and clamping block, one end of drawstring is fixed on locking
The bottom surface of block, the other end of drawstring are fixed on the top surface of limited block.Here stretching, the effect of fixed beam are to be convenient for fixed link
The placement of part is conducive to timely carry out grafting limit (as shown in Figure 2) to the first lockhole, the second lockhole.
The utility model has the advantages that：The utility model smart structural design, rationally, using shaft coupling, positioning pin,
Clamping block, handle carry out locking to valve when for valve wide open or full off state and ensure that equipment and pipeline maintenance personnel
Safe operation also can avoid the release of the dangerous energy and cause public safety hazards；It is capable of the complete of control valve using locating slot
Open state or full off state or half-open position, it is good to the locking effect of valve, it is worthy of popularization.
