Description
Technical field
Valve technology field is the utility model is related to, more particularly to a kind of lock controlled ball valve.
Background technology
On the various pipelines of the industry such as water supply, supply, pipeline transportation, valve has a wide range of applications.In many occasions,
People need to be controlled valve, to prevent other people to be arbitrarily opened and closed.Therefore, the valve with locking device is very practical.
The existing valve species with locking device is a lot, and its structure is also different.Some are to use mechanical cylinder lock or electricity
Son lock carrys out the handle or valve rod of Locked valve.This method is although feasible, but because different valves needs different keys
It is inconvenient or password is opened, therefore for controlling the administrative staff of substantial amounts of user.Using magnetic principles,
Opened using specific purpose tool, be a kind of more satisfactory method.
As Chinese patent storehouse discloses a kind of Anti-dismantling ball-valve [Application No.:201310025948.8], it is mainly characterized by
Magnetic automatic locking mechanism is further comprises, by pressing handle, the back-moving spring compression in handle, handle when handle moves down
Cut in two relative positions the opposite magnet straight pin of magnetic it is attracting after enter stem groove, realize and lock.Such a Anti-dismantling ball-valve
Following defect be present:Because the Anti-dismantling ball-valve need to press down on handle, to realize locking, and press handle and be easy to cause behaviour by mistake
Make, such as during ball valve is installed, the handle of imprudence pressing will pin ball valve, cause unnecessary trouble.
Chinese patent storehouse discloses a kind of lock controlled ball valve [Application No.:201420761195.7], including with neck
Valve body, neck are cylindrical in shape, and valve element and valve rod are provided with valve body, and valve rod outer end stretches out neck and cuts valve rod the inner outer rim provided with O-shaped
Circle.There is socket, valve rod the inner, which is plugged on the socket inscribe valve rod, can drive valve core rotation, on valve rod the inner on valve element lateral wall
A lockhole for being in strip is also extended radially through, lockhole both ends are plugged with both ends magnetic pole phase adjacent in a magnetic pole and two magnetic poles respectively
Instead, neck both sides offer the positioning hole with lockhole position correspondence respectively, and the two magnetic pole other ends are plugged on corresponding positioning respectively
The force piece for making two magnetic poles that there is opposite moderate tone is provided with hole, in neck, is also had when valve rod is inside on neck madial wall
The stopper slot for being caught in O-ring during translation.Following defect be present in such a lock controlled ball valve:When needing locking, first ball valve is closed, connect
Pull-up valve rod so that O-ring spins off out of stopper slot, now both ends magnetic pole phase adjacent on force piece and two magnetic poles
Under anti-collective effect so that two magnetic poles are reinserted into lockhole and lock valve rod, and such a lock controlled ball valve is complicated, operation
Cumbersome, valve rod is arranged in handle, is pulled also inconvenient.

Two second boss 304 are may also set up on the ground inwall of neck groove 307, two second boss 304 are oppositely arranged.Due to two it is spacing
Baffle plate 503 and second boss 304 are to be oppositely arranged ground, and therefore, another breach 504, which will be arranged on, opens spacing lug 501
Between postive stop baffle 503, so, upward handle 3 when ball valve is closed, two second boss 304 on handle 3
Corresponding breach 504 could be passed through simultaneously.
Described magnetic locking component includes at least two magnetic pins 8 and at least two springs 9, described valve rod hole 302
Inwall be provided with least two radial pin slots 306;The periphery wall of described valve rod 2 is provided with neck 202;Described magnetic pin
8 are slidably fitted in corresponding radial pin slot 306, and described spring 9 is located at corresponding magnetic pin 8 and the bottom land of radial pin slot 306
Between;When lock handle 3 is with valve rod 2, one end of described magnetic pin 8 is contained in described radial pin slot 306, described magnetic
Property pin 8 the other end be contained in described neck 202;When release lever 3 is with valve rod 2, one end of described magnetic pin 8 houses
In described radial pin slot 306, the other end of described magnetic pin 8 is against on the outer wall of described valve rod 2.Described radial direction
Cotter way 306 is provided with two, and two radial pin slots 306 are oppositely arranged, and correspondingly, described magnetic pin 8 and spring 9 are also all provided with
There are two.Described neck 202 can be ring-type or the counterbore corresponding with magnetic pin 8.
When described magnetic locking component lock handle 3 is with valve rod 2, the described lower surface of first boss 303 and valve rod 2
Certain operating range between the end face of one end be present, the operating range is the stroke that handle 3 moves downward, therefore, by setting
Putting the distance between first boss 303 and the end face of valve rod 2 can the stroke that moves downward of joystick 3.
The course of work of lock controlled ball valve of the present utility model is as follows:
The original state of ball valve is set as free switch state:Magnetic pin 8 staggers with the position of neck 202 on valve rod 2, magnetic
Property pin 8 end face contradict and be located in valve rod 2 in the side wall on the downside of neck 202.Described second boss 304 is held into activity space
In 505, second boss 304 is driven in the rotation of the downside of postive stop baffle 503 by handle 3.The lower surface of described first boss 303
It is against on the end face of one end of described valve rod 2.Handle 3 is by the second boss 304, the spacing lug 501 of unlatching and closes
Spacing lug 502 realizes 90 degree of rotary stoppers, and handle 3 turns over 90 degree clockwise or counterclockwise, realizes that ball valve turns off or on.
During locking ball valve:Ball valve is in and closed, now, second boss 304 is directed at described breach 504, and is located at institute
The position directly below for the breach 504 stated.The handle 3 is lifted upwards, and handle 3 is transported upwards together with magnetic pin 8 on its interior
It is dynamic.When described magnetic pin 8, which moves to, to be located at the neck 202 in the side wall of valve rod 2 in same horizontal line, the magnetic
Magnetic pin 8 is pushed into neck 202, handle 3 is locked with valve rod 2 by pin 8 by the effect of spring 9.Now, on described handle 3
Second boss 304 be located just in described breach 504, handle 3 is rotated by limitation, realizes ball valve locking, i.e., described in
The stroke of handle motion be less than second boss lower surface described in when ball valve be in opening and described breach upper edge it
Between distance.
When opening ball valve:Solution lock key 10 is placed on outside handle 3, described solution lock key 10 is lid-like, described
Solve and be provided with magnet 1001, described magnetic pin 8 with the corresponding position of the magnetic pin 8 on handle 3 on the inwall of lock key 10
The end magnetic relative with magnet 1001 is different.When solve lock key 10 be placed on handle 3 it is outer when, magnet 1001 is by magnetic pin 8 to remote
Direction from neck 202 attracts, and magnetic pin 8 acted on during neck 202 is exited by the elastic force of spring 9, magnetic pin 8 with
The lower wall card jail of described neck 202, magnetic pin 8 can not be bounced back in radial pin slot 306 by frictional force effect.Now, upwards
Light handle 3, handle 3 drives magnetic pin 8, and motion can be such that magnetic pin 8 departs from the lower wall of neck 202 upwards, move back magnetic pin 8
Go out neck 202 to be held into radial pin slot 306.At the same time, cancel the lifting power upward to handle 3, acted on by return spring 7,
By 3 downward bullet of handle untill first boss 303 is contradicted on the end face of valve rod 2.Now, the second boss 304 of handle 3 is worn
Breach 504 is crossed, has been located in the lower section of described breach 504, ball valve is in free switch state.
