Description

UPPER ADAPTER OF VALVE-CONTROLLING EQUIPMENT

The present invention relates to an upper adapter of a valve control device, surrounding the stem on the yoke sleeve, for manipulating rotation of the yoke sleeve and the stem projecting from the body of the valve. will be.

In general, a valve (valve) is installed in a pipe (pipe) for inducing the flow of the fluid to control the flow rate and flow rate of the fluid on the flow path of the fluid. Here, the valve is connected to a plurality of valves in an industrial field and used together with a lock tool. The locking tool is a lock and a chain applied to the valve, and requires a user's direct manipulation of the valve before handling the valve's handle, and thus does not prevent a user's manipulation error.

As an alternative to this, the lock and chain are being replaced by valve interlocks in the valve. The valve interlock is a protective device installed on the valve to prevent a user's manipulation error after the valve handle is manipulated by applying a mechanical mechanism to the valve without direct manipulation by the user before manipulation of the handle of the valve. That is, the valve interlock accommodates one or two control keys before the valve handle is operated to sequentially control the opening and closing of the valve after the valve handle is operated.

The coupling relationship between the valve and the valve interlock according to the prior art is described in FIG. 1 . Here, to simplify the description of the invention, the valve is limited to the gate valve 10, and the valve interlock 70 is limited to a handwheel (or handle) valve interlock. The gate valve 10 has a stem 3 and a yoke sleeve 6 protruding from the valve body 9, as shown in FIG. 1(a).

The yoke sleeve 6 rotates with the stem 3 relative to the valve body 9 while passing through the stem 3 . In order to install the valve interlock 70 to the gate valve 10, the stem 3 and the yoke sleeve 6 are connected to the sleeve rotating part 24 of the sleeve fixture 30 as shown in FIG. 1(b). It is surrounded by a retaining nut (28). Specifically, the sleeve rotating part 24 surrounds the yoke sleeve 6 and is fixed to the yoke sleeve 6 because of the angular shape of the yoke sleeve 6 , and the fixing nut 28 is a stem on the sleeve rotating part 24 . (3) surround.

After installing the sleeve fixing body 30 on the valve body 9, as shown in FIG. ) and screwed to the interlock body 50 . The interlock body 50 may accommodate one control key 44 or 48 or two control keys 44 and 48 . The interlock body 50 receives the handle connector 60 through the upper portion of the interlock body 50 and is screwed with the handle connector 60 .

The handle connecting body 60 transmits the rotation torque of the valve handle (not shown) to the sleeve fixing body 30 through the interlock body 50 . Here, the valve handle surrounds the handle connector 60 and is fixed to the handle connector 60 because of the angular shape of the handle connector 60 . Accordingly, when one control key 44 or 48 is accommodated in the interlock body 50 , the sleeve fixing body 30 and the handle connecting body 60 do not rotate through the interlock body 50 , so the stem (3) and the yoke sleeve (6) do not rotate.

Unlike this, when the two control keys 44 and 48 are accommodated in the interlock body 50 , the sleeve fixing body 30 and the handle connecting body 60 are rotated through the interlock body 50 and the stem Rotate (3) and the yoke sleeve (6). Here, as shown in FIG. 1( d ), the sleeve fixing body 30 , the two control keys 44 , 48 , and the interlock body 50 and the handle connecting body 60 connect the valve interlock 70 . make up However, when the size of the gate valve 10 is changed, the size of the valve handle is also changed.

In a cascade, since the handle connecting body 60 must correspond to the valve handle in a size individually tailored to the size of the gate valve 10 , a plurality of the handle connector 60 must be provided according to the type of the gate valve 10 . The presence of a plurality of the handle connecting body 60 puts a burden on the user when the handle connecting body 60 is installed on the interlock body 50 . Therefore, when the handle connector 60 is not fitted in a custom size to the valve handle, the valve interlock 70 is not installed on the interlock body 50 by the user in the engagement relationship of the handle connector 60 and the valve handle. does not prevent installation mistakes.

On the other hand, the valve interlock is similarly disclosed as a prior art in Korean Patent Publication No. 10-2135788.
