Description

Lock controlled ball valve

The utility model relates to a kind of valve, particularly relates to a kind of valve that limits random keying.

Advantages such as the valve that uses on the pipeline of carrying liquid, gas mostly is open greatly, promptly grasps with mechanism and exposes, and it has simple to operate, and is easy to use.But because the exercisable randomness of this valve, thereby,, want to limit other people and arbitrarily open and close then very difficult the assurance perhaps for the needs of safety and insurance for being in the occasion of opening or closing within a certain period of time.For example, current city heat supply, water supply, air feed department need because of charge, and it is just difficult through accomplishing to desire to make certain user's supply valve to be in closed condition under the situation of not removing equipment.For solving this class problem, people have invented valve with lock." the valve that can be locked " of Chinese patent CN2191946Y bulletin, " a kind of valve of device with lock " of CN2222277Y bulletin are exactly two examples wherein.Though they have all solved the problem that restriction arbitrarily opens and closes, and all exist disadvantages such as complex structure, cost height.

The purpose of the utility model is to provide a kind of effect that control arbitrarily opens and closes that both had, have again simple in structure, make install, closed lock controlled ball valve easily.

The technical solution of the utility model is achieved in that it is made up of the lock control mechanism that valve body, spool, Sealing and the valve rod that is connected with spool and control valve rod open and close, lock control mechanism comprises the lock that is shaped on the valve body, be contained in above the lock and be fixed in lock core on the valve rod, have the lockhole more than two or two on the lock core, the magnetic padlock pearl is housed on each lockhole; Corresponding having for the fall restraining groove of position locking of magnetic padlock pearl is when this restraining groove goes to spool complete opening or closed position at lock core, relative with the magnetic padlock pearl on the lock.The lock core end face is with the magnetic bead lid, and magnetic bead covers and is with the flexible handle of opening lock core and driving valve rod, and the position of relative each the magnetic padlock pearl in this handle bottom surface is embedded with inhales pearl on the magnetic.Taper knob is combined on the lock core, on inhale the magnetic padlock pearl of pearl in the lock core; Because two magnetic poles are opposite, produce suction mutually, so the magnetic padlock pearl is inhaled from the lock restraining groove, at this moment, handle can drive valve rod and rotate, and realizes closing or opening of ball valve.When ball valve is in when closing or opening fully, unload lower handle, the magnetic padlock pearl of lock core falls the position in restraining groove, thereby lock core can not rotate relative to lock, thereby has locked the rotation of valve rod.

The utility model can also be embedded with under the magnetic on restraining groove and the corresponding position of magnetic padlock pearl inhales pearl, and its magnetic attraction can accurately fall the position less than the magnetic attraction of last suction pearl to the magnetic padlock pearl on restraining groove to guarantee the magnetic padlock pearl.

Below in conjunction with embodiment shown in the drawings the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A sectional view of Fig. 1.

Lock controlled ball valve is contained in Sealing 2, the spool 1 in the valve body 14 and is stirred the valve rod 13 of spool 1 keying and the lock control mechanism composition that control valve rod 13 rotates by valve body 14.

Be threaded between water intake 3 in the valve body 14 or water outlet and the valve pocket and be integral; The top of valve body 14 has lock 14a, and high-temperature seal ring 12 and gland nut 4 are housed between lock 14a and the valve rod 13.

Lock control mechanism comprises lock 14a, be fixed on lock core 9 on the lock 14a with pin 16 activities, lock core 9 central sleeve are on the square column on valve rod 13 tops, have four on the lock core 9 and be symmetrically distributed in the lockhole 9a of same garden on week, magnetic padlock pearl 10 is housed on the lockhole 9a, lock 14a goes up corresponding having for fall " cross open form " restraining groove 15 of position locking of magnetic padlock pearl 10, when this restraining groove 15 goes to spool 1 complete opening or closes at lock core 9, just relative with magnetic padlock pearl 10 positions, and being embedded with suction pearl 11 under four magnetic on the relative restraining groove 9a, following suction pearl 11 is opposite with magnetic padlock pearl 10 polarity.Be with magnetic bead lid 5 at lock core 9 end faces, be provided with the handle 6 that the double as key is used above the magnetic bead lid 5, these handle 6 central sleeve are embedded with on the position of the relative magnetic padlock pearl 10 in handle 6 bottom surfaces and inhale pearl 7 on the magnetic on the square projection at lock core 9 centers, and fixing with cover plate 5.When handle 6 is enclosed within on lock core 9 and the valve rod 13, on inhale pearl and attract to move on the magnetic padlock pearl 10, and break away from restraining groove 9a, handle with sleeve 6 can drive valve rod 13 and open or close ball valve this moment; When handle 6 goes to the ball valve complete opening or closes, take down handle 6, magnetic padlock pearl 10 is inhaling under the attraction of pearl 11 down, falls the position on restraining groove 15, thus the rotation of locking valve rod 13.

Obviously, the utility model compared with the prior art, have reasonable in design, the structure letter Single, be easy to processing, advantage is installed, easy to use etc., can be installed on all kinds of special-purpose pipelines and make With.
