Description

Magnet controlled locking-valve

Technical field

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

Background technique

Current city heat supply, water supply, air feed department need because of charge, under the situation of not removing equipment, desire to make certain user's supply valve to be in closed condition and just are difficult to accomplish.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 is exactly wherein two to be listed as.Although the structure of these Valve with lock has nothing in common with each other, use the mechanical type lock body mostly, open with key.Though this method is more safe and reliable, but the installation quantity of Lock controlled valve is many and when key be special messenger when coming keeping, the custodial staff carries and operates the very trouble that just seems, obscures easily, inconvenience is managed.On May 5th, 2000 State Intellectual Property Office to have announced the patent No. be 01246349.3 magnetic Lock controlled valve, it addresses the above problem preferably, but only is confined on the magnetic control of ball valve, promptly opens the angle of rotating between 0 °-90 °, is restricted during use.

Summary of the invention

The purpose of the utility model is at the problems referred to above, provides a kind of and unifies with one or several magnetic key cover magnet controlled locking-valve that open, that anti-destructive is strong.

To achieve these goals, the utility model has adopted following technical proposal: it comprises valve body, be contained in the valve seat on the valve body, place the spool in the valve body, inner valve rod that connects with spool and upper shield are on valve seat and valve rod and magnetic lock device separable with it and be used to the key cover opening magnetic lock device, have magnetic.Wherein said magnetic lock device comprises the lock that is enclosed within on the valve seat, is contained in the interior and lock core separable with valve seat, that be Cap structure for box-like container of lock; The lock core periphery has equally distributed lockhole and magnetic padlock hole more than three or three, be embedded with movable steel ball on each lockhole, have the locked groove that matches with it with the corresponding valve base surface of steel ball, when steel ball is pushed on the locked groove by lock, lock, lock core just are fixed on the valve seat, and involution is lived valve rod.In each above-mentioned magnetic padlock hole telescopic magnetic padlock pearl is housed, has locating slot, releasing slots on the position that relative magnetic padlock pearl of lock inwall and lockhole horizontally rotate.For flexibly connecting, and between them, be provided with the limited post and the camber line shape restraining groove of protrusion between lock core end face and the lock roof, when this restraining groove rotates to the one end at lock, steel ball on the lock core and the releasing slots on the lock over against; When lock rotates to the other end of restraining groove, the locating slot on magnetic padlock pearl and the lock over against.Above-mentioned key cover is the cover shape, can be linked on the lock, is provided with the magnetic patch of same polarity on relative magnetic padlock pearl position; As long as key cover is linked on the lock relative with the magnetic padlock pearl, the magnetic padlock pearl is under the effect of the same polarity repulsive force of magnetic patch, in the retraction magnetic padlock hole, at this moment, rotate lock and make the locked groove of steel ball disengaging valve seat enter the releasing slots of lock, magnetic lock device is desirable from valve seat, valve rod.Above-mentioned key cover center is provided with the axis hole that matches with valve stem tip, and in valve stem tip, key cover can drive valve rod rotation rising or decline by the double as handle, reaches the purpose of valve opening and closing with shaft hole sleeve.

In the utility model, magnetic lock device covers valve rod, has controlled the keying of valve.In the time of will operating valve, at first directly be linked on the lock, can eliminate the locked state of magnetic lock device with key cover; Secondly, take off magnetic lock device, utilize the shaft hole sleeve of key cover to be combined on the valve rod, can drive the unlatching of gate valve or close.

Valve body of the present utility model can be a brake valve body, also can be other valves such as ball valve, stop valve.

Advantages such as the utility model compared with prior art has use, convenient management, and anti-destructive is strong, and is safe and reliable are particularly suitable for a large number of users is carried out using on the pipe-line system of control and management.

Embodiment

As shown in Figure 1, this magnet controlled locking-valve comprises the valve body of being made up of component such as valve body 11, valve seat 9, spool and valve rods 10 and is enclosed in the magnetic lock device on the valve rod 10 and opens magnetic lock device and separable magnetic key cover 2.

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, magnetic lock device comprises lock 3, place the lock core 4 in the lock 3 and be contained in steel ball 7, magnetic padlock pearl 6 on the lock core 4.Lock core 4 is the cover shape, the roof center has the axis hole that matches with valve seat 8 coupling shafts, have four equally distributed magnetic padlock hole 4c and lockhole 4b on the sidewall of lock core 4, magnetic padlock pearl 6, steel ball 7 place respectively in magnetic padlock hole 4c, the lockhole 4b, wherein in each magnetic padlock hole 4c spring 5 is housed also, one end of spring 5 withstands on the magnetic padlock pearl 6, and the other end is against on the hole wall of magnetic padlock hole 4c.Also be provided with the limited post 4a of protrusion on lock core 4 end faces, on lock 3 roofs, have camber line shape restraining groove 3a accordingly, like this, can limit the scope of rotation between lock core 4 and the lock 3.Lock 3 inwalls horizontally rotate with respect to magnetic padlock hole 4c, lockhole 4b and have four equally distributed locating slot 3b and releasing slots 3a on the position.Valve seat 9 is provided with the locked groove 9a that cooperates with steel ball 7, when lock 3 when restraining groove 3a rotates to the one end, steel ball 7 and releasing slots 3a over against, at this moment, steel ball 7 is gone up retraction releasing slots 3a from locked groove 9a, lock core 4, lock 3 can be removed from valve seat 9.When lock 3 rotates to the restraining groove 3a the other end, magnetic padlock pearl 6 and locating slot 3b over against, magnetic padlock pearl 6 stretches into locating slot 3b under the effect of elastic force, at this moment, lock core 4 can not rotate each other with lock 3, lock 3 inwalls make steel ball 7 stretch into locked groove 9a, and lock 3, lock core 4 pin valve rod 10, referring to Fig. 4, Fig. 5, Fig. 7.

Be connected by the coupling shaft rotary moveable on screw 8, the lock 3 between lock core 4 in the utility model and the lock 3.Spring 5, magnetic padlock pearl 6 in the 4c of magnetic padlock hole also can replace with two same polarity magnetic padlock pearls 6, referring to Fig. 6.Magnetic padlock of the present utility model hole 4c, lockhole 4b are generally 3-8.

Key cover 2 also is the cover shape, can be linked on the lock 3, be embedded with magnetic patch 1 on the relative magnetic padlock pearl 4a position, both sides with magnetic padlock pearl 6 same polarities, this magnetic patch 1 makes magnetic padlock pearl 4a retraction magnetic padlock hole 4a leave locating slot 3b with the repulsive force that magnetic padlock pearl 4a produces, thereby lock 3 can be rotated relative to lock core 4, when going to releasing slots 3a and steel ball 7 when relative, steel ball 7 leaves locking slot 9a, referring to Fig. 8, Fig. 9, magnetic lock device can be opened, have the axis hole 2a that cooperates with valve rod 8 tops at the center of key cover 2, by this axis hole 2a, key cover 2, can drive valve rod 8 rotates, therefore, this key cover 2 can be with handle 2b, referring to Figure 10.
