Description

Manual valve {A MANUAL VALVE}

The present invention relates to a manual valve, and more particularly, to a manual valve of a new structure capable of opening and closing a flow path inside a valve body portion with a small force.

In general, a valve is provided in an intermediate portion of a pipe having a large diameter and is used to control the flow of a fluid supplied through the pipe.

1 is a side cross-sectional view showing a conventional valve.

Stem 3; And a driver bushing 10 that is configured in a tubular shape extending in the vertical direction, is screwed to the thread 3a of the upper end of the valve stem 3 and rotatably coupled to the yoke 5 at the lower end.

Further, in the conventional valve, a ring-shaped handle 4 is provided outside the driver bushing 10.

Therefore, when the operator rotates the handle 4 forward and backward, the driver bushing 10 is rotated, and the valve body 2 by the action of the screw thread 3a of the driver bushing 10 and the valve stem 3 By opening and closing the middle portion of the flow path 1a while rising and descending, the flow of the flow path 1a passing through the valve housing 1 can be controlled.

However, in such a conventional valve, the operator manually rotates the handle 4 to open and close the flow path 1a, and since the pressure of the fluid passing through the flow path acts on this valve, the handle 4 is rotated to open the flow path ( There was a problem that a lot of force was required to open and close 1a).

In addition, in this way, as a lot of force is required to rotate the handle 4, when the operator rotates the handle 4 to close the flow path 1a, the valve cannot be completely sealed, and thus leakage There was a problem that could occur.

In particular, since it takes a lot of power when rotating the handle 4, there are many cases in which the operator rotates the handle 4 by combining a separate ranch, etc., in this case, the problem that the handle 4 may be damaged. Has occurred.

This problem is the same for all types of valves provided in the middle of the pipe and used to control the flow of fluid through the pipe.

Therefore, there is a need for a new method for a manual valve opening/closing drive device capable of solving this problem.

An opening/closing drive unit located at one side of the valve body and for driving the valve body; And
One end is connected to the valve body, the other end includes a valve stem connected to the opening and closing drive unit,
The opening and closing drive unit may include a main body housing; A first driving source disposed on one side of the main body housing; And a driving arm connecting the first driving source and the valve stem and transmitting a driving force of the first driving source to the valve stem,
The first driving source may include a first rotation shaft penetrating the interior of the main body housing, being fastened to the main body housing to rotate, and including a first screw thread in a predetermined area; And a first handle fastened to one end of the first rotation shaft and positioned outside one side of the main body housing,
The driving arm unit may include a horizontal driving arm unit for horizontally moving in the longitudinal direction of the first rotation shaft of the first driving source; And a hinge driving arm part for hinge movement based on the horizontal driving arm part,
When the first rotation shaft penetrates the inside of the body housing and is fastened to the body housing, the first region of the first rotation shaft is disposed in a through hole located on a first side of the body housing, and the first The second region of the rotation shaft is disposed in a groove located on the second side of the main body housing,
Since the first region of the first rotation shaft and the second region of the first rotation shaft do not contain a thread, the first rotation shaft is based on the first region of the first rotation shaft and the second region of the first rotation shaft. To rotate in place,
The predetermined region of the first rotation shaft including the first screw thread corresponds to a region between the first region of the first rotation shaft and the second region of the first rotation shaft,
The horizontal driving arm portion, a horizontal driving arm body portion; It is located at one side in the longitudinal direction of the body of the horizontal drive arm, is fastened to the first screw thread of the first rotation shaft, and includes a first fastening hole having a second screw thread therein,
The second screw thread of the first fastening hole is fastened to the first screw thread of the first rotation shaft, and the first screw thread rotates according to the rotation of the first rotation shaft, so that the second screw thread follows the first screw thread. Characterized by moving,
The hinge driving arm portion, a hinge driving arm body portion; A first fixing hole positioned at one side of the hinge driving arm body in the longitudinal direction, and fastened and fixed to a predetermined area of the valve stem; And a hinge shaft moving hole positioned on the other side of the hinge driving arm body in the longitudinal direction, and through which the hinge shaft is inserted and moved,
The hinge shaft moving hole is configured in an elliptical shape, and the hinge shaft moves along the hinge shaft moving hole. The method of claim 1,
The opening and closing drive unit may include a cover housing covering the main body housing; And a second driving source disposed above the cover housing,
The second driving source is a manual valve including a second handle that is directly coupled to the other end of the valve stem. The method of claim 2,
The first driving source and the second driving source are manually operated by a user's force, and by the operation of the first driving source or the second driving source, or by simultaneous operation of the first driving source and the second driving source. , The valve stem rotates,
By rotation of the valve stem, the valve body connected to one end of the valve stem rotates, so that the valve body opens and closes a flow path inside the valve body. The method of claim 1,
The horizontal drive arm part is located on the other side of the body part in the longitudinal direction of the horizontal drive arm part, and includes a hinge shaft fastening hole through which the hinge shaft is inserted and fastened. delete
