Abstract

The utility model relates to a valve using the magnetic principle to control. The valve mainly comprises a magnetic locking device for the control of the valve rod rotation and a magnetic key set. The magnetic locking device includes at least two groups of or a plurality of springs and magnetic lock columns opened on the valve seat. A lock piece is covered on the magnetic lock column. A locking hole and a locating hole are opened on the related position of the magnetic lock column and valve rod on the lock piece. In nature state, the magnetic lock column is inserted in the locking hole to make the lock piece not rotate. The related position of the key set wall and the magnetic lock column is embedded with the same polarity magnetic block. A key column is arranged on the round core, so that the key set is covered to the valve seat and then the key column can inserted to the valve rod and drive the valve rod to rotate. The utility model has advantages of simple structure, low cost and strong anti-destructivity and is particularly applied to the control and management of a plurality of users for the pipeline system in use.

Description

Magnetocontrolled lock 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 the supply valve at certain family 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 CN222277Y bulletin is exactly wherein two to be listed as, although the structure of these Valve with lock has nothing in common with each other, uses the mechanical type lock body mostly, opens with key.Though this method is more safe and reliable, to the installation quantity of Lock controlled valve many and when key be special messenger when coming keeping, carrying and operating of custodial staff just shows very trouble, 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 be confined on the magnetic control of ball valve, promptly open the angle of rotation between 0-90, be restricted during use, and complex structure, the cost height.

The model utility content

The purpose of the utility model is at the problems referred to above, provides one to urge Magnetocontrolled lock valve simple in structure, that anti-destructive is strong.

In order to realize above-mentioned purpose, the utility model adopts following technical proposal: it comprises valve body, be contained in the valve seat on the valve body, place the spool in the valve body, the inner valve rod that connects with spool and be contained in valve seat and valve rod between magnetic lock device and the key cover that is used to open this magnetic lock device and has magnetic.Wherein said magnetic lock device is included in the lockhole that has very less on the valve seat more than 2, spring, magnetic padlock post are housed in the lockhole, on valve seat, be stamped locking plate, locking plate is having locking aperture and positioning hole on lockhole, the stem position relatively, positioning hole matches with sectional shape, the size of valve rod, can also cover cap be arranged involution on the locking plate.The magnetic padlock post is stretched in locking aperture under nature, makes locking plate not rotate.Valve rod is positioned at the position of positioning hole upper section and is shaped as square or hexagon, or other geometrical shape except that circle, to guarantee that the valve rod energy of rotation drives locking plate and rotates together.Be embedded with the magnetic patch of same polarity on described key cover inwall and the magnetic padlock post relative position, key cover is equipped with key cylinder on the center of circle, valve stem tip has shape, size and the groove that matches of key cylinder in cross section, so that when key cover is linked on the valve seat, key cylinder can plug together on the valve rod and can drive valve rod and rotate.

Because the magnetic padlock post under nature, under the effect of elastic force, stretch on the locking aperture that is through locking plate, and the positioning hole of locking plate is linked on the valve rod, so locking plate and valve rod can not rotate, valve is in the lock state.If key cover is linked on the valve seat, and when making each magnetic patch on it relative with the magnetic padlock post, the magnetic padlock post is under the effect of magnetic repulsion, move down and locking aperture on the clutch locking plate, at this moment, valve rod, locking plate, key cylinder can rotate with key cover, thereby reach the purpose of unlatching or throttle down.

The utility model compared with prior art has simple in structurely, and advantage such as component are few, and cost is low, and anti-destructive is strong, and is easy to use is specially adapted to a large number of users is carried out using on the pipe-line system of control and management.

In the utility model, the magnetic padlock post is generally 2-4, and the best is 4, and evenly distributes.

At key cylinder described in the utility model, valve rod fit mutually, the shape of cross section is preferably square, and the positioning hole shape on the locking plate matches with it.

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

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

Fig. 1 is that the utility model key cover does not overlap fashionable structural representation.

Fig. 2 is that Fig. 1 removes A behind the cover cap to schematic representation.

Fig. 3 be Fig. 1 remove B behind the cover plate to schematic representation.

Fig. 4 is the structural representation behind the utility model key cover fit.

Embodiment

As shown in Figure 1, this Magnetocontrolled lock valve comprises the valve body of being made up of parts such as valve body 8, valve seat 7, spool and valve rods 9 and is contained in the magnetic lock device on the valve seat 7 and opens this magnetic lock device and separable magnetic key cover 2.

Magnetic lock device is included in and has four equally distributed lockholes 10 on the valve seat 7, place spring 11, magnetic padlock post 12 in the lockhole 10, cover the cover cap 6 on locking plate 5, valve seat 7 at locking plate on the valve seat 75 and inclusion, locking plate 5 relative lockholes 10 and valve rod 9 positions correspondingly have locking aperture 51 and positioning hole 52, positioning hole 52 can be linked on the valve rod 9 just, and can rotate with valve rod 9, rotating with valve rod 9 in order to guarantee locking plate 5, valve rod 9 is square in positioning hole 52 locational cross sections.Locking aperture 51 and lockhole 10 over against the time, magnetic padlock post 12 can stretch into locking aperture 51 naturally under the effect of elastic force, at this moment, locking plate 51 can not rotate relatively, thereby the rotation of locking valve rod 9, referring to Fig. 2.

Key cover 2 is the cover shape, can be linked on the valve seat 7, be embedded with magnetic patch 3 on relative magnetic padlock post 12 of its inner roof wall or lockhole 51 positions with magnetic padlock post 12 same polarities, involution has cover plate 4 on the magnetic patch 3, this magnetic patch 3 and magnetic padlock post 12 relative near the time, the repulsive force that produces makes magnetic padlock post 12 leave locking aperture 51 and in the retraction lockhole 10, referring to Fig. 3.Square key cylinder 1 is housed on the center of circle of key cover 2, and corresponding valve rod 9 tops have sectional shape, the big or small groove 91 that matches with key cylinder 1; When key cover 2 was linked on the valve seat 7, key cylinder 1 plugged together just on groove 91; If make magnetic patch 3 and magnetic padlock post 12 over against the time, key cover 2 can drive valve rod 9 rotations, therefore, this key cover 2 can have handle, referring to Fig. 4.

Magnetic padlock post 12 in the utility model can be 2 or 3, also can be 5 or 6, the cross section that plugs together mutually between valve rod 9 and the key cylinder 1 can be triangle, hexagon or other geometrical shape except that circle, as long as locking device can drive valve rod 9, locking plate 5 rotations when opening state.
