Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of magnetic locking valve.
Background technique
At present, ball valve has been widely used in the industrial fields such as civil area and oil, chemical industry.For example, in civil area, ball valve has become indispensable controlling component in residential building water supply, gas burning system.But existing ball valve in use cannot open and close operation to it and be limited; open and close structure all protrudes from outside valve body; unprotect device; easily destroyed and open steathily; and any people that can touch ball valve can be random unlatching or close, caused strengthening the property management difficulty of public utilities and community.
Certainly, on market, now also there is the valve with locking device to be widely used.Although the structure of Valve with lock is different, mostly use mechanical lock body, need to open with private key.Although this method is more safe and reliable, but when the installation quantity of Valve with lock is many and key is while being taken care of by special messenger, because the corresponding private key of each valve can not be general, custodial staff carries all private key inconveniences, and when operation also need to check private key, operation is trouble very.
Summary of the invention
The purpose of this utility model be for prior art exist the problems referred to above, proposed a kind of simple in structure, the magnetic locking valve of easy-to-operat.
The purpose of this utility model can realize by following technical proposal: a kind of magnetic locking valve, comprise the inner valve body for cavity, the two ends of valve body are respectively feed-water end and waterexit end, in described valve body, be provided with ball core and valve rod inner and that ball core is connected, described valve body upper end has bump, stretch out outside bump the outer end of described valve rod, it is characterized in that, described valve rod and bump axial restraint, the sidepiece of described bump has positioning hole, the sidepiece of described valve rod has mounting hole, in described mounting hole, be provided with spring and magnetic patch, the two ends of described spring lean respectively on mounting hole bottom and magnetic patch and magnetic patch leans on the madial wall at bump, in the time that valve rod turns to mounting hole and positioning hole and faces, magnetic patch falls in positioning hole, this magnetic locking valve also comprises a release lever that can be socketed on bump and be connected with valve rod, described release lever inner side has the magnet same with magnetic patch Magnetic Phase with position of positioning hole corresponding section.
Valve is in the time of opening state, and the position of positioning hole on the mounting hole on valve rod and valve body bump staggers mutually, and the magnetic patch in mounting hole is resisted against on the madial wall of bump under the elastic force effect of spring.When needs are during by valve closing, because valve rod outer end is positioned at outside valve body bump, therefore utilize the instrument can rotation valve rod, in the time valve rod being turned to positioning hole and mounting hole and faces, magnetic patch has lost the barrier effect of bump madial wall and has fallen in positioning hole in the elastic force effect of spring, thereby the bump of valve rod and valve body is locked mutually, and valve also cannot rotate in closed condition and valve rod.
Need to and open valve to valve release time, release lever is enclosed within on bump and is connected with valve rod, because release lever inner side has the magnet same with magnetic patch Magnetic Phase, according to the principle of two like magnetic poles repel each other, magnetic patch under magnetic force to inside contracting, lose the connection of magnetic patch, the bump of valve rod and valve body is locked no longer mutually, just can be with ovable valve stem that valve is opened again by rotating release lever like this.
In above-mentioned magnetic locking valve, the sidepiece of described bump has curve bath, and described valve rod sidepiece and corresponding section, curve bath position have projection, and described projection is positioned at curve bath.
When valve rod rotates, and the projection of sidepiece is while contacting with the cell wall at curve bath two ends respectively, and valve is in opening or closed condition, utilizes the match slewing area of incompatible restriction valve rod of projection and curve bath.
In above-mentioned magnetic locking valve, the external diameter that described magnetic patch is cylindric and magnetic patch is identical with positioning hole, described positioning hole runs through the sidepiece that is arranged at bump, described bump is fixed with door outward, inner side, described door upper end has gear edge and keeps off along the upper end face that is resisted against bump, and described valve rod outer end flushes through the exterior edge face of door and valve rod exterior edge face and door.
Magnetic patch is cylindric and its external diameter is identical with positioning hole, in the time that valve rod turns to positioning hole and mounting hole and faces, magnetic patch is inserted in positioning hole, in order to prevent that magnetic patch from outwards flying out under the elastic force effect of spring from positioning hole, at bump, door is set outward, magnetic patch can be stopped by door again in by valve rod and bump locking like this.
In above-mentioned magnetic locking valve, described door and bump are connected through door sidepiece the pin that penetrates bump sidepiece by one.
In above-mentioned magnetic locking valve, as another kind of technological scheme, described magnetic patch is spherical, and the external diameter of described magnetic patch is greater than the internal diameter of positioning hole.The external diameter of magnetic patch is greater than the internal diameter of positioning hole, and in the time that positioning hole and mounting hole face, magnetic patch can part fall in positioning hole under the elastic force effect of spring, so also can make valve rod and the bump of valve body lock mutually like this.
In above-mentioned magnetic locking valve, the outer end of described valve rod has connecting groove, on the face that described release lever inner side and valve rod outer end face, has the contiguous block matching with connecting groove shape.
In above-mentioned magnetic locking valve, as another kind of scheme, the outer end of described valve rod has square contiguous block, on the face that described release lever inner side and valve rod outer end face, has the connecting groove matching with contiguous block.
After release lever is enclosed within on the bump of valve body, valve rod is connected with the mode that release lever cooperatively interacts with connecting groove by contiguous block, like this when the magnet in release lever just can be with ovable valve stem to rotate by rotating release lever after magnetic patch release.
In above-mentioned magnetic locking valve, on described release lever, there is the joint of column, the upper end sidepiece of described joint offers through hole, in described through hole, is provided with inserted link, and one end of described inserted link has the block that external diameter is greater than through hole internal diameter.
In the time of release, inserted link is inserted in the through hole of joint on release lever, because inserted link one end has the block that external diameter is greater than warp in through hole, when therefore inserted link being moved to block and joint and leans along through hole, now the arm of force reaches maximum, and user can be like a cork by valve release.
Compared with prior art, the magnetic patch that the utilization of this magnetic locking valve is arranged in mounting hole locks valve rod and valve body in the time of valve closing, simple in structure, easy to operate, only need to utilize the instrument that can be connected with valve rod by valve closing, magnetic patch just can lock valve rod automatically, and only release lever need be enclosed within and on valve body, utilize the magnetic force of the magnet in release lever automatically valve rod to be carried out to release when release, saves time and laborsaving; In addition, because magnetic patch is arranged between valve rod and the bump of valve body, and be provided with door outward at bump, not only improved well the aesthetics of valve, and strengthened Security due to outside not being exposed to, be difficult for destroyed.
