Description

Lower adapter of valve control unit

The present invention relates to a lower adapter of a valve control device, surrounding a yoke sleeve, for manipulating the rotation of a stem or yoke sleeve projecting from a body of a valve.

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 (c), the sleeve fixture 30, the two

control keys

44 and 48, and the interlock body 50 and the handle connecting body 60 are connected to the valve interlock 70. make up However, if the size of the gate valve 10 is changed, the size of the yoke sleeve 6 is also changed.

Chained, the sleeve fixing body 30 must be provided in plurality according to the type of the gate valve 10 because it must correspond to the yoke sleeve 6 in individual sizes for each size of the gate valve 10 . The presence of a plurality of the sleeve fixture 30 puts a burden on the user when the sleeve fixture 30 is installed on the gate valve 10 . Accordingly, when the sleeve fixture 30 is not installed in a custom size to the gate valve 10 , the valve interlock 70 is the user's It 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.

The present invention has been devised to solve the problems of the prior art, and even if the size of the yoke sleeve is different depending on the size of the gate valve, it surrounds the yoke sleeve without providing a plurality according to the size of the yoke sleeve and the angular shape of the yoke sleeve It is an object of the present invention to provide a lower adapter of a valve control device so as to be securely fixed to the yoke sleeve using a , suitable for easily controlling the rotation of the stem and the yoke sleeve.

The lower adapter of the valve control device according to the present invention sequentially drives the stem on the yoke sleeve in the valve control device to operate the rotation of the yoke sleeve and the stem projecting from the valve body of the valve through the valve control device. and an upper adapter and an interlock body enclosing, and coupled to the interlock body and the upper adapter so as to surround the yoke sleeve while interlocking rotation of the upper adapter through the interlock body. a sleeve housing having a square hollow penetrating the yoke sleeve in a central region of the sleeve and having a guide portion facing the hollow portion of the fragment; first and second sleeve rotation restraint pieces positioned between one guide part and the other guide part in the sleeve housing and intermittently contacting the yoke sleeve; The first and second first and second sleeve rotation restraint pieces positioned between the first and second sleeve rotation restraint pieces to surround the yoke sleeve and pass through the first and second sleeve rotation restraint pieces to be rotationally fixed to the one guide part and the other guide part rotating member; First and second bumpers accommodated in the sleeve housing, positioned around the one guide part and the other guide part, and partially inserted into the one guide part and the other guide part to contact the first and second rotation members board; and an interlock connector coupled to the sleeve housing, contacting the first and second bumper plates, extending from the sleeve housing toward the interlock body, and inserted into the interlock body.
