[0001] VALVE ASSEMBLY WITH SECURITY APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valve assembly for opening and closing various piping, and more particularly, to a valve assembly for improving security and preventing any operation of a valve.

The valve is for opening and closing various piping, and operates by rotating the valve handle.

Conventional locking valves have a structure that prevents the valve handle from rotating arbitrarily by fastening the lock to the valve handle.

However, such a locking-type locking valve can arbitrarily break the lock and operate the valve, which has a problem of poor security.

Handle locking device of ball valve (Korean Utility Model No. 20-0273448)

The object of the present invention is to improve the security of the valve assembly so as to prevent opening and closing operations of the valve at will.

The present invention relates to a valve handle having a key integrally formed on a central shaft thereof; And a valve body including a valve body, a cylindrical lock piece rotatably assembled to the valve body, and a valve disk integrally rotating with the lock piece, The valve assembly is rotated only when the valve body is inserted.

The valve handle may include a guide rod protruding in the same direction as the key, and the lock bundle may include an insertion groove into which the guide rod is inserted,

It is more preferable that a plurality of the guide rods and the insertion grooves are provided radially.

The valve assembly according to the present invention has the effect of preventing the valve from being opened or closed by arbitrarily making the valve handle itself become a key.

The terms and words used in the present specification and utility model registration claims should not be construed to be limited to ordinary or preliminary meaning and the inventor should appropriately interpret the concept of the term appropriately in order to describe its own design in the best way It should be interpreted in terms of meaning and concept that conforms to the technical idea of the present invention based on the principle that it can be defined. It should be noted that the embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention, It should be understood that various equivalents and modifications are possible.

FIG. 1 is a view showing a valve handle and a valve body of a valve assembly according to a first embodiment of the present invention, FIG. 2 is a view showing a state in which a valve handle of the valve assembly according to the first embodiment is coupled to a valve body Fig.

The valve assembly 100 according to the embodiment of the present invention is characterized in that the valve handle 110 and the valve body 120 are detachably formed.

The present invention is intended to improve the security of the valve operation and to prevent an operator other than the authorized person from arbitrarily opening and closing the valve.

By providing a structure in which the valve handle 110 can be detachably attached to the valve body 120, only the authorized person can carry the valve handle 110 to operate the valve, and after the operation is completed, the valve handle 110 is detached , And the valve can not be opened or closed without the valve handle (110).

In the conventional case, the valve is managed to the extent that the valve handle is fastened to the valve body by using a lock or a chain. In this case, it is troublesome to separately manage the key, and the position of the valve is not completely fixed, And had problems. There was also a risk that the locking device could be damaged and the valve could be operated at will.

However, according to the present invention, the valve handle 110 can be separated so that the valve can not be operated at all without the valve handle 110, thereby improving the security of the valve operation.

The present invention further includes a key 112 in the valve handle 110 and a lock assembly 124 in the valve body 120 so that the key 112 of the valve handle 110 is engaged with the key 112 of the valve body 120 By allowing the valve to be operated in a state of being inserted into the lock bundle 124, the security is further improved.

In the valve handle 110 according to the embodiment of the present invention, the key 112 is integrally formed on the central axis.

The valve body 120 according to an embodiment of the present invention includes a valve body 122 connected to a pipe, a cylindrical lock piece 124 rotatably assembled to the valve body 122, And an opening / closing piece 126 integrally rotating with the bundle 124.

The lock bundle 124 can rotate relative to the valve body 122 only when the key 112 is inserted so that the valve can not be operated unless the valve handle 110 is inserted, So that the security of the valve is improved.

FIG. 3 is a view showing a state in which the valve handle and the valve body of the valve assembly according to the second embodiment of the present invention are separated, and FIG. 4 is a cross-sectional view of the valve body of the valve assembly according to the second embodiment, And Fig.

The present embodiment is characterized in that the valve handle 110 is further provided with a guide rod 114 together with a key 112. In this case, when the torque for turning the valve handle 110 is transmitted only to the key 112, there is a fear that the key 112 may be damaged.

The present embodiment has a guide rod 114 protruding in the same direction as the key 112 on the valve handle 110 in order to disperse the torque generated when the valve handle 110 is operated, An insertion groove 128 corresponding to the guide rod 114 is provided to disperse the torque when the valve handle 110 is operated in the key 112 and the guide rod 114 to improve the durability of the key 112 .

At this time, the guide rods 114 may be arranged radially around the key 112.

As described above, in the valve assembly according to the present invention, the valve handle is detachably attached to the valve body, and the valve can be operated only when the key provided in the valve handle is inserted into the lock assembly formed in the valve body , Thereby improving the security of the valve operation.

It is to be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, and the scope of the present invention will be indicated by the appended claims, rather than the foregoing detailed description. It is to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit and scope of the appended claims.
