Description
Technical field
The present invention relates to magnetic locking valve technical field, more particularly to it is a kind of can the magnetic lock that is turned on and off of single direction rotation
Close gate valve.
Background technology
Magnetic lockable gate valve is to reach closure member in control valve (magnet, clamping screw and spring) by the active force of magnetic force
Opening and closing, belong to a kind of magnetic lock.On the valve for being generally used for some important, specific positions and function, valve is prevented
Door is used by any switch.
At present, magnetic lockable gate valve need to can be opened and closed by specific purpose tool, facilitate water supply administrative department to valve
Control, specific purpose tool typically rests in water supply administrative department, and no matter the product, which is turned on or off, is both needed to by specific purpose tool
(supporting magnetic key) could be realized.
But, the shortcoming of such a magnetic lockable gate valve is embodied in：On the one hand when valve water outlet end subscriber is in an emergency
When need to close valve cut-out water supply, such as pipeline leak within doors, user can only contact with administrative department, and now leak situation can not
Stop, often influencing whether the vital interests of resident family, cause unnecessary loss；On the other hand the valve of some special occasions is not
It can arbitrarily close, but need very easily to open, existing magnetic lockable gate valve can not meet use demand.
The content of the invention
It is an object of the invention to propose a kind of unidirectional magnetic lockable gate valve, to solve magnetic lock present in prior art
Close the technical problem that gate valve must be opened and closed by specific purpose tool.
For up to this purpose, the present invention uses following technical scheme：
A kind of unidirectional magnetic lockable gate valve, including fixed lid, the fixation have covered removable cover, and the removable cover includes upper
Interface, the fixed lid includes lower interface, and the upper interface is provided with upper circular hole, and the lower interface is provided with lower circle
Hole, the upper circular hole and the lower circular hole are oppositely arranged, and latch assembly is provided with the upper circular hole and the lower circular hole；
The latch assembly includes the spring and the permanent magnet in the upper circular hole being located in the lower circular hole, institute
State and be located at the spring in lower circular hole provided with locking post, the tip portion of the locking post is located in the upper circular hole, described
Lock and spin is provided between post and the permanent magnet；
The upper circular hole clockwise or counterclockwise direction downstream be provided with along the upper circular hole circumferencial direction set
Arc groove, described arc groove one end connects with the upper circular hole, the arc groove and the upper circular hole junction
Depth is less than the depth of the upper circular hole, rotates clockwise or rotate counterclockwise direction, the depth of the arc groove is gradually
Reduce until being flushed with the upper interface.
Further, the upper interface and the lower interface are provided with multigroup upper circular hole being oppositely arranged and institute
State in lower circular hole, the upper circular hole and the lower circular hole and be equipped with the latch assembly；
The multiple upper circular holes and the lower circular hole are located on same circumference, and the arc of each upper circular hole connection
Connected in star is set clockwise or counterclockwise along identical.
Further, the top of the removable cover is provided with projection, and the raised side wall, which is provided with, to be used to fix valve rod
Pin hole.
Further, the outer wall of the removable cover is provided with annular knurl.
Further, it is described raised for square shaped prism or regular hexagon prism.
Further, it is in cone-shaped intermediate incline that the top of the locking post, which is provided with,.
Further, the cone angle of the intermediate incline is obtuse angle.
A kind of unidirectional magnetic lockable gate valve that the present invention is provided, in use, passing through locking group between fixed lid and removable cover
Part is locked, that is, the spring descended in circular hole promotes locking post, and locking post pushes into spin and permanent magnet in upper circular hole, locks post
Tip portion is located in upper circular hole.The upper circular hole of removable cover along the circumferential direction has the arc in (or counterclockwise) direction clockwise recessed
Groove, therefore removable cover can rotate freely along (or counterclockwise) direction clockwise, specifically, removable cover is along (or counterclockwise) clockwise
Direction is rotated, and arcuately groove is moved locking post, can gradually be moved to the lower section of interface, and then can release the lock of locking post
Tight state；Conversely, when removable cover is along when (or clockwise) direction is rotated counterclockwise, locking post can enter circular hole internal resistance on removable cover
Only removable cover continues to rotate, wherein in rotary course, when locking column top is located in arc groove, and the top of locking post coordinates rolling
The rotation of ball, makes locking post to enter in circular hole, it is to avoid block of the permanent magnet to locking post, now need to be by special tool
Rotation can be continued by having in the lower circular hole for pushing permanent magnet and spin and promoting locking post to enter fixed lid.
The unidirectional magnetic lockable gate valve, can be achieved being turned on and off for unidirectional rotation, during this, without using special
Instrument, e.g., in family expenses water lines, can be achieved unidirectional shutoff operation, and opening needs specific purpose tool to operate, such a situation
Under, when drainage occurs in interior conduit, magnetic lockable gate valve voluntarily can be closed by conventional instrument, can avoid making
Into loss.
The unidirectional magnetic lockable gate valve, need to be by specific purpose tool during unlatching (or closing), and closing (or when opening) only needs
Manpower or by general tool, more hommization when using, to unidirectional when can meet emergent moment or special key requirement
The manipulation demand of magnetic lockable gate valve, the scope of application is more extensive.
