Description
Technical field
The utility model belongs to valve technology field, is related to a kind of dual locking ball valve of magnetic.
Background technique
Ball valve is very common valve, by ball valve in standard GB/T21465-2008 " valve term " is defined as: opening and closing
The valve that part [sphere] is driven by valve rod, and rotated around the axis of valve rod.Pipeline may be implemented by the rotation of sphere
The circulation or cut-off of interior medium；When flow of media, ball valve is in the open state；When the maximum flow of flow of media, at ball valve
In fully open state；When medium cut-off circulation, ball valve is in off state.It is often fixedly connected on the valve rod of ordinary ball valve
Handle, anyone can change the use state of valve body by rotational handle, other people optionally change valve in order to prevent
Use state, need it is a kind of can be with the ball valve of locking valve rod.
Chinese patent literature data, which discloses, proposes a kind of magnetic locking ball valve [application number: 201120318553.3；Bulletin
Number: 202215837U], including valve body, ball valve core, valve rod, magnet valves lock and magnetic wheel of unlocking, the rotatable peace of ball valve core
Between valve inleting water mouth and water outlet, ball valve core is equipped with the fluid latus rectum being connected with entery and delivery port, valve body upside
Wall extends a stem bearing, and the stem bearing that one end of valve rod passes through valve body upper side wall is connected with ball valve core, magnet valves lock by
Magnetism is unlocked on the removable stem bearing for being sheathed on valve body upper side wall of wheel control.It is opened up on the periphery wall of stem bearing
There is annular arc groove, magnet valves lock includes outer cover and inner cover, and the inner sidewall of inner cover is corresponding with stem bearing annular arc groove
At least three spherical pores are offered on position, spherical pore is provided with ball, and the outer diameter of ball is greater than the sidewall thickness of inner cover, outer cover
Inner sidewall, which is located at below ball, is provided with annular cavity, between inner cover that free end and outer cover inner sidewall far from stem bearing
At least two springs are laid with, magnetic lock device is additionally provided between inner cover and outer cover, magnetic lock device is remote in inner cover
From lockhole is symmetrically arranged on that one end periphery wall of valve body, it is recessed that annular is provided on outer cover position corresponding with inner cover lockhole
Slot, lockhole are provided with magnetic substance and reset spring, and magnetic substance free end is resisted by reset spring in outer cover annular groove, magnetic
Property wheel of unlocking be equipped with and the magnetic identical magnet of magnetic substance.
When magnet valves lock is in the lock state, the ball in inner cover makes ball under the press of the inner sidewall of outer cover
A part protrusion inner cover is embedded in the annular arc groove of valve body stem bearing, makes entire magnet valves lock that cannot be detached from valve body, ball
Valve realizes normal locking.When needing Open valve, magnetism, which is unlocked, to take turns to be sheathed on the magnet valves side of locking and press makes magnetism
Magnet in unlocking wheel is corresponding with the magnetic body position that magnet valves are locked, because of the magnetism of magnet and magnet valves lock in magnetic wheel of unlocking
The magnetic pole of body is homopolarity, and under the action of magnetic homopolarity mutually repels, the magnetic substance of magnet valves lock is to reset spring connected to it
It generates pressure to be entirely retracted in lockhole, so that magnet valves lock outer cover can be mobile relative to inner cover, while outer cover under the action of the spring
Rise, until ball is not by a part of retraction outer cover of the press of outer cover inner sidewall when the spherical pore of its annular cavity face inner cover
When annular cavity, so that it may take away entire magnet valves lock from valve body, after magnet valves lock is removed from valve body, magnetism be unlocked and is taken turns
Rectangular open keyhole alignment valve rod on square protrusion rotary valve rod can Open valve, ball valve realize normal use.
But this locking ball valve uses two blocks of magnet in the outside of outer cover, magnet pushes the magnetic substance that magnet valves are locked open
Afterwards, it will be able to magnet valves lock be removed from valve body, greatly reduce the anti-theft effect of ball valve in this way.
Summary of the invention
