Description

Magnetic control valve

Technical field

The utility model belongs to a kind of valve, particularly a kind of magnetic control valve door.

Background technique

On heat supply, water supply or supply air line, general valve can freely openable.For heating installation company, water utility or Gas Company, the user needs to charge in use.But in actual use, some user exists phenomenon of defaulting, brings influence for the management of supplying unit.Therefore, need a kind of valve with lock, control switching, the user who does not on schedule pay dues is carried out stop supplies by administrative staff.

The Lock controlled valve of present domestic appearance is more, many Chinese patents of also having applied for.As the Ball Valve With Lock that Chinese patent 99254574.9 provides, it is made up of mechanical cylinder lock and ball valve two-part, and valve body connects with lock body, and valve rod connects with lock core.During operation, key is inserted in the lock core, key drives valve core rotation by the valve rod that connects with lock core, controls the switching of ball valve.

Adopt mechanical cylinder lock to wait the deficiency of control valve to be lockhole, make administrative staff can not implement throttle down the defaulting subscriber easily by artificial obstruction.

Because valve normally is in the environment of comparison humidity, its lock core gets rusty easily, and has also influenced the normal use of Valve with lock.

Adopt the shortcoming of common lockset control valve also to be each valve key of need wearing, key is a lot, carries and use equal inconvenience.

To this, although many people have proposed a lot of improvement projects, as the magnetic card lock valve that Chinese patent 99242803.3 provides, it is that valve and magnetic card lock are combined, and controls moving of dead bolt by magnetic card lock.Very feasible on this theoretical method, but during practical application, its product structure complexity, cost is also higher, is difficult to be widely used.

Summary of the invention

The purpose of this utility model is at present existing the problems referred to above, adopts magnetic principles, and a kind of simple and reasonable, easy to operate, practical magnetic control valve is provided.

The purpose of this utility model is to be achieved by following manner: this magnetic control valve comprises valve body, spool in the valve body, valve rod and lock body, lock body is cylindrical, be connected as a single entity with valve body, the inner of valve rod connects with spool, the outer end is positioned at lock body, a columniform lock nut is set in the above-mentioned lock body, the external diameter of lock nut is slightly less than the internal diameter of lock body, be embedded with magnet in the lock nut, the side of lock nut has an annular groove, fixing a retaining head on the inwall of lock body, the height of retaining head is less than the width of annular groove, and annular groove has the breach that a retaining head can pass through to the lock nut bottom in the lock nut, and this magnetic control valve also is furnished with one and opens handle, open in the handle magnet is housed, and the unlatching handle is provided with the shape that is complementary with the valve rod outer end.

In this magnetic control valve, lock nut can separate with lock body.In lock nut embeds lock body, and when making retaining head on the lock body inwall enter in the annular groove by breach, rotate lock nut, lock nut just can not break away from lock body.Because the outer end of valve rod is positioned at lock body, so this moment, valve rod can't rotate, the open and-shut mode of valve also just can not change.

Open this magnetic control valve and need special-purpose unlatching handle.On this unlatching handle magnet is housed, makes by magnet and open handle and hold lock nut, rotate simultaneously and open handle and drive lock nut and rotate together, when the breach in lock nut is in the position of retaining head, just can pull out lock nut.After removing lock nut, will open handle and insert in the lock body, and make and open handle and match, and rotate and open handle and makes valve rod, with valve opening or close along with rotation together with the valve rod outer end.

Above-mentioned lock nut end face is the plane, and after retaining head enters annular groove in the lock nut, and the end face of lock nut is equal with the lock body upper edge or a little less than the lock body upper edge.

The outer end of above-mentioned valve rod is embedded with iron core or magnet.Include in the lock body process at lock nut, lock nut is held and is not easy to drop out, and helps practical operation.

The outer end shape of above-mentioned valve rod is preferably triangle, cross or in-line, and opening on the handle also has the shape that is complementary therewith.

Compared with prior art, advantage of the present utility model is:

1, when valve is in the lock state, lock nut is positioned at lock body, and the surface of lock nut is the plane, and no lockhole can prevent artificial destruction.

2, owing to can adopt a special opening handle to control each magnetic control valve, the historical facts or anecdotes border is easy to operate, is convenient to administrative staff and carries, and increases work efficiency.

3, this magnetic control valve is rational in infrastructure, and opening ways is simply ingenious, has higher utility.

Embodiment

As shown in Figure 1, the magnetic control valve that provides of the utility model comprises valve body 1, spool 2, valve rod 3, lock body 5 and lock nut 6.In the present embodiment, spool 2 is spherical, and valve is a ball valve.Valve rod 3 the inners in the valve body 1 connect with spool 2.Lock body 5 is a cylindrical shape, is connected as a single entity with valve body 1.Valve rod 3 outer ends are positioned at lock body 5.

Also seal between valve rod 3 and the valve body 1 by O shape rubber seal 4.

The shape of lock nut 6 as shown in Figure 4 and Figure 5, lock nut 6 is cylindrical, its sidepiece has annular groove 61 and a breach 62.The end face of lock nut 6 is the plane.The external diameter of lock nut 6 is slightly less than the internal diameter of lock body 5.A retaining that is connected as a single entity with lock body 5 50 is arranged in the lock body 5, and retaining 50 can pass through breach 62 and annular groove 61.After lock nut 6 was included in the lock body 5, retaining 50 embedded in the annular grooves 61 by breach 62, can be limited to lock nut 6 in the lock body 5.At this moment, the end face of lock nut 6 is a little less than the upper edge of lock body 5.

As shown in Figure 1, a permanent magnet 60 is embedded in the lock nut 6.

In the present embodiment, it is that material is made that valve body 1, lock body 5 and lock nut 6 all adopt copper.

The shape of the unlatching handle 7 of this magnetic control valve is opened in the handle 7 and also is embedded with a permanent magnet 70 as shown in Figures 2 and 3.Utilize to open magnet 60 adhesive mutually in magnet 70 and the lock nut 6 in the handle 7, lock nut 6 is rotated along with the rotation of unlatching handle 7 in lock body 5.In the time of need taking out lock nut 6, adopt to open handle 7, when making lock nut 6 go to the position of its breach 62 retaining 50 in lock body 5, pull out lock nut 6 and get final product.

As shown in Figure 1, in the present embodiment, the end of valve rod 3 is embedded with iron core 30.When lock nut 6 has just been included in the lock body 5, utilize the magnet 60 in the lock nut 6 to hold iron core 30, make lock nut 6 be not easy to break away from lock body 5, reverse lock nut 6 then and be fixed in the lock body 5.

In the present embodiment, the outer end of valve rod 3 is shaped as triangle.As Fig. 2 and Fig. 3, it is leg-of-mutton cavity 71 that there is a cross section that is complementary therewith the end of unlatching handle 7.After removing lock nut 6, the outer end of valve rod 3 is entered in the cavity 71 of opening handle 7, rotate and open handle 7, can open or throttle down.

As shown in Figure 1 and Figure 4, the bottom of lock nut 6 has a cavity 63.This cavity 63 enters for the outer end of valve rod 3.Like this, can make lock nut 6 and lock body 5 sizes do lessly, compact structure helps reducing the manufactured materials and the product cost of this magnetic control valve.
