Fig. 1 is the structural representation of prior art magnetic lockable valve.
Fig. 2 is the utility model example structure schematic representation.
Fig. 3 is that the utility model embodiment is installed in the structural representation on the valve.
Embodiment
Now with specific embodiment the utility model is further specified by reference to the accompanying drawings.
With reference to figure 2, present embodiment discloses a kind of valve Sealing mechanism, its valve gap 1 top of being located at valve is used for the rotation of restriction valve rod 2 with the opening and closing of control spool, described locking framework comprises opens key 3, bonnet 4 and lock tube 5, being located on the bonnet 4 of described unlatching key 3 activities, described lock tube 5 is rotating to be located on the valve gap 1 of valve, and be fixedly connected with the valve rod 2 of valve by bearing pin 6, being sheathed on the lock tube 5 of described bonnet 4, and can do lost motion around valve rod 2 outsides of valve, be provided with the idle running axially stop block between the valve rod 2 of described bonnet 4 and valve, described idle running axially stop block is that the periphery at described valve rod 2 has annular groove 21, the position of the corresponding stem ring connected in star of the periphery of described bonnet 4 is evenly equipped with 3 hinge lasts, be inserted with respectively pony axle in described each hinge last and consign 41, described each pony axle is consigned and 41 is stretched into respectively in the annular groove 21 of valve rod 2, described pony axle 41 those ends that stretch in the annular groove 21 of consigning are provided with the hemispherical projections corresponding with annular groove 411, the idle running limit stoper makes the bonnet 4 can not axially taking exercises along valve rod 2, but can rotate along valve rod 2, described lock tube 5 upper, on the lower both ends of the surface wall body respectively along circumferentially evenly offering 4 mutually corresponding upper lockhole and lower lockholes that arrange, be respectively equipped with lower magnetic steel 52 in described each time lockhole, describedly be respectively equipped with upper magnetic steel 51 in the lockhole on each, described upper magnetic steel 51 and lower magnetic steel 52 corresponding end polarity arrange on the contrary, offer on described bonnet 4 and lock tube 5 contacted those end-face wall and lock tube 5 corresponding the stretching into and the open hole 42 that ejects for each upper magnetic steel 51 of lockhole on each, be respectively equipped with on described unlatching key 3 position corresponding with bonnet 4 each open hole with upper lockhole in the opposite keying magnet steel 31 of upper magnetic steel 51 magnetic, for thereby the magnetic force that opens and closes magnet steel is sucked upper magnetic steel in the open hole greater than the magnetic that the magnetic force of lower magnetic steel overcomes lower magnetic steel, between described upper lockhole and the lower lockhole is 2mm apart from a ', thereby so that upper magnetic steel can be held by lower magnetic steel when opening key and not working, when opening key work, upper magnetic steel can be unlocked in the magnet steel suction open hole.
Described bonnet 4 tops are circular protrusions 43, the general opener of circular protrusions of bonnet top is difficult for clamping, can further remind this valve of people not open by the general purpose tool clamping, further guarantee the Security that valve uses, further prolonged the working life of magnetic valve.
Such as Fig. 3, the utility model embodiment is installed in the structural representation on the valve, when the needs Open valve, the opened lock key case of carrying is located at the bonnet top, because of the upper magnetic steel magnetic pole opened on facing the wall and meditating on unlatching magnet steel and the lock tube in the key opposite, under the effect that the magnetic heteropole is inhaled mutually, the unlatching magnet steel that upper magnetic steel is unlocked in the device sucks in the open hole of bonnet, so that each upper magnetic steel is between bonnet and lock tube, thereby so that bonnet can rotate with opening the key turn, then drive lock tube and rotate, rotate the open and close that realize spool 7 thereby drive the valve rod that fixes with lock tube; Do not work when packing up when opening key, because the interattraction of magnetic different poles, the lower magnetic steel of lock tube below can hold the upper magnetic steel of lock tube top and make upper magnetic steel break away from the open hole of bonnet, like this, when valve is illegally opened by other opener, because upper magnetic steel does not contact with the open hole of bonnet, so that bonnet can and be done lost motion in all sides of valve rod with general opener rotation, thereby valve can not opened because of malice to be damaged, guaranteed to a certain extent the Security that magnetic valve uses, reduced the phenomenon that magnetic valve is maliciously damaged in the pipeline, bring convenience for the maintenance work of magnetic valve, prolonged the working life of magnetic valve.
Based on the aforementioned techniques scheme, needing only apart from a ' between described upper lockhole and the lower lockhole all can realize the purpose of this utility model between 1.5～3.5mm.
The above record, only for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do all belong to the claim that this creation is advocated, and are not limited to those disclosed embodiments.
