However, because of its easy opening and closing, the ball valve is most likely to be opened by non-workers without effective management, resulting in loss of production or waste of common resources.

SUMMERY OF THE UTILITY MODEL

Therefore, to foretell problem, the utility model provides a simple structure, have an encryption ball valve of encryption function.

In order to achieve the above object, the technical solution of the present invention is to provide an encryption ball valve, which comprises a ball valve body, a valve cover disposed on the ball valve body, a water inlet channel and a water outlet channel disposed along the radial direction of the ball valve body, and a valve plate disposed between the water inlet channel and the water outlet channel for controlling the opening and closing of fluid, a valve rod is arranged above the valve plate and inside the ball valve body, a first channel is arranged above the ball valve body, the lower end part of the valve rod is fixedly connected with the valve plate, the upper end part of the valve rod penetrates through the first channel and is positioned in the valve cover, an opening and closing rod can be penetrated through the valve cover in a sliding mode up and down, a first gear ring is fixedly arranged at one end of the opening and closing rod and is positioned in the valve cover, the valve rod is fixedly provided with a second gear ring which can be meshed with the first gear ring, and the valve cover is provided with an encryption device for limiting the downward sliding of the opening and closing rod.

The further improvement is that: the encryption device comprises a limiting block, the limiting block is fixedly arranged on the opening and closing rod and located in the valve cover, a first annular groove and a second annular groove which are used for rotating the limiting block are formed in the valve cover, the first annular groove is located above the second annular groove, and a first channel which is communicated with the limiting block and used for sliding the limiting block is formed between the first annular groove and the second annular groove.

The further improvement is that: the distance between the first ring groove and the second ring groove is the same as the distance separating the first gear ring and the second gear ring.

The further improvement is that: and a rotating hand wheel is fixedly arranged at the other end of the opening and closing rod.

The utility model has the advantages and the beneficial effects that:

1. when the ball valve is opened, need go into first passageway through the stopper card in, then promote the first ring gear on the opening and closing rod and the second ring gear block on the valve rod, just can open the ball valve, and the stopper is located the valve gap, has fine disguise, if not professional staff, when rotating the hand wheel, opening and closing rod idle running, avoided the ball valve to be opened, prevent that other people from maliciously opening the ball valve, cause the waste of loss or public resources in the production, and make things convenient for staff's management thereof.

2. The management of community public resource is made things convenient for, avoids in the public place, and child opens the ball valve, causes the wasting of resources, perhaps other people maliciously steals water.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-2, an encryption ball valve comprises a ball valve body 1, a valve cover 6 disposed on the ball valve body 1, a water inlet channel 2 and a water outlet channel 3 radially disposed along the ball valve body 1, a valve plate 4 disposed between the water inlet channel 2 and the water outlet channel 3 for controlling the opening and closing of fluid, a valve rod 5 disposed above the valve plate 4 and inside the ball valve body 1, a first channel 13 disposed above the ball valve body 1, a lower end of the valve rod 5 fixedly connected to the valve plate 4, an upper end of the valve rod 5 passing through the first channel 13 and located in the valve cover 6, an opening and closing rod 9 slidably disposed on the valve cover 6 up and down, a first gear ring 8 fixed to one end of the opening and closing rod 9 and a first gear ring 8 disposed in the valve cover 6, a second gear ring 7 capable of meshing with the first gear ring 8 fixed to the valve rod 5, be equipped with on the valve gap 6 and be used for restricting the encryption device that opens and close 9 gliding of pole, encryption device includes stopper 10, stopper 10 is fixed to be located and opens and close on the pole 9 and stopper 10 is located valve gap 6, seted up in the valve gap 6 and supply stopper 10 pivoted first annular 11 and second annular 12, first annular 11 is located second annular 12 top, set up between first annular 11 and the second annular 12 and be linked together and supply stopper 10 gliding first passageway 13. When the valve is used, the line rotates the opening and closing rod 9, the limiting block 10 on the opening and closing rod 9 is located on the first channel 13, then the opening and closing rod 9 is pressed, the opening and closing rod 9 is pushed to slide downwards, the first gear ring 8 and the second gear ring 7 on the opening and closing rod 9 are meshed at the moment, then the opening and closing rod 9 is rotated, the opening and closing rod 9 drives the limiting block 10 to rotate in the second gear ring 12, the limiting of the limiting block 10 on the opening and closing rod 9 is avoided to rotate, meanwhile, the opening and closing rod 9 drives the first gear ring 8 to rotate, the second gear ring 7 is driven to rotate, then the valve rod 5 is driven to rotate, finally, the valve plate 4 is driven to rotate, and the ball valve is opened.

In order to prevent the sliding of the opening and closing rod 9 and to enable the quick opening of the ball valve, the distance between said first and second

annular grooves

11, 12 is the same as the distance of separation between the first and

second ring gears

8, 7. The distance between the first gear ring and the second gear ring is the same, so that the first gear ring 8 and the second gear ring 7 can be meshed when the limiting block 10 enters the second annular groove 12, the ball valve can be opened by rotating the limiting block at once, and the opening and closing rod 9 can be prevented from moving up and down.

In order to facilitate the rotation of the opening and closing rod 9, a rotating hand wheel 14 is fixedly arranged at the other end of the opening and closing rod 9.

Having shown and described the basic principles and essential features of the invention and its advantages, it will be understood by those skilled in the art that the present invention is not limited by the embodiments described above, which are merely illustrative of the principles of the invention, but is susceptible to various changes and modifications without departing from the spirit and scope of the invention, all of which are intended to be covered by the appended claims and their equivalents.
