Description
Technical field
The present invention relates to a kind of ball valve, specifically refer to for HVAC, drinking water pipeline keying, a kind of non-return valve being provided with magnetic key adverse current can be stoped, not allowing user to open voluntarily.
Background technique
HVAC, the maintenance of drinking water pipeline and operation management, need to register one's residence end device when a failure occurs it at pipeline, anyly can to close per capita, but user can not open voluntarily, namely public relations is allowed, stop the private valving opened, prior art adopts at the non-return valve of end device two series connection of registering one's residence, wherein ball-cock device is in locking can, when a failure occurs it, user blinds off a line by the ball valve outside can, before failture evacuation, maintenance man blinds off a line by the ball valve in can, pipeline is opened voluntarily to prevent user's malfunction, so, make pipeline complicated, cost occupies high, and it is inconvenient to install, and time-consuming, therefore, prior art exists pipeline complexity, cost occupies high, to install inconvenience problems and shortcomings.
Summary of the invention
For above-mentioned prior art Problems existing with not enough, the present invention adopts and arranges at valve rod base and valve rod place the magnetic lock be made up of pin-and-hole, bullet groove, magnetic bullet and spring, wherein, bullet groove, magnetic bullet and spring are located at valve rod place, pin-and-hole is located on the inwall of valve rod base, when ball valve core is in closed condition position, bullet groove is corresponding with pin-and-hole to communicate; Ball valve core is in the valve rod base inwall place of opening state position without pin-and-hole; The top of valve rod is also provided with spin slot; Adopt by being provided with magnetic core, revolve the magnetic key that the rotation set of tongue and handle form, and it is relative that magnetic core and the magnetic pole of magnetic bullet are arranged to the same sex; When ball valve core is in closed position, magnetic bullet inserts in pin-and-hole by spring action, and valve rod and valve rod base lock mutually; During application, when ball valve core is in closed position, rotation set is enclosed within valve rod base, revolving tongue inserts in spin slot, because of the magnetic pole two like magnetic poles repel each other of magnetic core and magnetic bullet, magnetic bullet pushes in the bullet groove of valve rod by magnetic core, and valve rod and valve rod base unlock mutually, pull rotatable handle rotation set, revolve tongue and make ball valve core be diverted to enable possition through spin slot band ovable valve stem; When ball valve core is in enable possition, herein because valve rod base is without pin-and-hole, therefore valve rod and valve rod base are in lock-free state mutually, even if without magnetic key, user also can close ball valve by rotary valve rod by a word turn screw, namely, allow public relations, stop the private technological scheme opened, a kind of non-return valve being provided with magnetic key is provided, is intended to by magnetic key, permission be diplomatized, stop the private pipeline opened, reaches the object simplifying pipeline, reduce costs, be convenient to installation.
The object of the present invention is achieved like this: a kind of non-return valve being provided with magnetic key, comprise valve body, valve rod base, valve rod, ball valve core, antireverse valve spool, union and magnetic key, wherein: the internal channel being provided with hollow centered by described valve body, the copper shell of the circular tube shaped that left and right two ends open wide, being provided with above in the middle part of valve body is protruding upward, the valve rod base of up big and down small cylinder stepped shape tubulose, the center of valve rod base is provided with and communicates with described internal channel, the pore of up big and down small cylinder stepped shape is called valve rod hole, symmetrically on the front and back inwall of the large step in described valve rod hole top be respectively equipped with the blind hole that the circular port that blocked up by plug riveting forms and be called pin-and-hole, the axis of described pin-and-hole is fore-and-aft direction,
Described valve rod is the copper component of up big and down small cylinder stepped shape, and the rectangular recess that the top of valve rod is provided with left and right directions is called spin slot, and the limit, left and right two of the large step post jamb in valve rod top is arranged with circular blind hole and is called bullet groove; In described bullet groove, ecto-entad slides and is provided with magnetic bullet and spring; Described magnetic bullet is columniform magnet, and described spring is cylindroid helicalcoil compression spring; Two described magnetic bullets are identical towards the magnetic polarity of respective described bullet groove bead; The bottom of stem lower portion small stair cylinder is provided with the tenon of the rectangle protruded for connecting ball valve core downwards;
Described magnetic key by being provided with magnetic core, revolve the rotation set of tongue and handle is formed, described rotation set is the steel components of up-small and down-big cylinder stepped shape, the through hole that rotation set top small stair cylinder is provided with left and right directions is called handle hole, and described handle hole slides and is installed with the shaft-like handle of steel cylinder; Be provided with upwards recessed circular groove below the large stepped cylinder in described rotation set bottom and be called grooving, symmetrically respectively on the cell wall on the limit, left and right two of described grooving be embedded with the magnetic core flushed with cell wall, the magnet of described magnetic core to be long limit the be rectangular block shape of above-below direction; The magnetic axis of described magnetic core is left and right directions, described magnetic core towards the magnetic polarity of described grooving cell wall with to be located at described valve rod identical towards the magnetic polarity of the magnetic bullet of described bullet groove bead, i.e. the same sex; The center of described grooving bottom land is provided with downward protrusion, long limit is the rectangle of left and right directions revolves tongue, described in revolve tongue and valve rod described spin slot be slidably matched;
Ball valve core is arranged in the described internal channel of valve body and is in opening state, and valve rod is pushed down through pressure ring and is rotatably positioned at described valve rod hole, and the described tenon of valve rod is connected with ball valve core, and described bullet groove is corresponding with described pin-and-hole is positioned at same imaginary elevation plane; Antireverse valve spool is positioned at the right side of valve body ball valve core, and union is connected to the right output port place of valve body;
By being located at the pin-and-hole of described valve rod base and being located at the bullet groove of described valve rod, magnetic bullet and spring and constituting magnetic lock, when ball valve core goes to closed position through valve rod, magnetic bullet is by spring action, in addition the repulsion of two mutual like poles of magnetic bullet, stretch out valve rod post jamb to insert in pin-and-hole, now valve rod and valve rod base lock mutually;
The face, direction of structure representation is divided into up, down, left, right, front, rear side, wherein, before be face in the face of main body, after be and described before relative face.
Working principle and beneficial effect
During application, when ball valve core is in closed position, the rotation set of magnetic key is enclosed within valve rod base, revolves tongue and insert in spin slot, because of the magnetic pole two like magnetic poles repel each other of described magnetic core and described magnetic bullet, and repulsion is greater than the mutual repulsion of two magnetic bullets, magnetic bullet pushes in the bullet groove of valve rod by magnetic core from described pin-and-hole, and valve rod and valve rod base unlock mutually, now, pull rotatable handle rotation set, revolve tongue and make ball valve core half-twist to enable possition through spin slot band ovable valve stem;
When ball valve core is in enable possition, due to the pin-and-hole that nothing on the inwall of valve rod base is herein corresponding, therefore valve rod and valve rod base are in lock-free state mutually, even if without magnetic key, user also can drive ball valve core to close ball valve by rotary valve rod by a word turn screw.
