The present invention inserts an intermediate gear for selectively connecting power to the center of the gear group that connects the drive shaft of the motor and the valve shaft of the opening / closing handle, thereby providing manual control and electric control as well as electric control. It relates to a valve opening and closing control device, and in particular, a handle mounting hole provided with a clamping member on a valve driving shaft installed on the same axis as the valve shaft, and at the same time, the valve driving shaft performs a limited rotational movement within a 90 ° deployment range. It relates to a valve opening and closing control device provided with a clamper configured to prevent rotation.

In general, the valve opening and closing device for selectively opening and closing the supply passage is installed in the pipeline for transporting liquefied gas or other highly flammable combustible materials, depending on the application and installation methods, such as home and industrial use In general, they are classified into a manual type for manually operating the open / close handles exposed to the outside and an electric type for controlling it with the power of a motor.

However, since the electric switchgear cannot be operated in an emergency in which the power supply is interrupted, a manual combined electric switchgear that supplements this point has also been proposed in various forms.

Nevertheless, they are also composed of relatively complex mechanical elements, and the operation reliability and the reliability of the operation are greatly reduced.

For example, the valve opening and closing device proposed in Korean Utility Model Publication No. 85-1523 is configured to selectively operate by manual and vibration by arranging a motor with a motor on one side with a spring. Although the power side of the motor and the opening / closing handle are not exactly matched, it causes unnecessary malfunction of the motor idling and the opening and closing of the valve is not performed smoothly. In addition, the handle does not have a separate rotation angle control means. It has been frequently observed that malfunctions occur frequently, such as rotating at this arbitrary angle, causing flammable material to flow out without the valve opening or closing correctly.

The present invention devised in order to solve such a conventional problem, by forming a moving groove having a predetermined development range on the drive valve integrally, the groove is regulated by a stopper inserted in the form of pins Its main purpose is to provide a valve opening and closing control device for both manual and electric light with improved reliability that allows the opening and closing angle to be maintained at exactly 90 °.

Another object of the present invention is to provide a handle mounting hole at the lower end of the valve drive shaft and a clamping means at the mounting hole so that the valve valve shaft and the valve shaft assembly position where the handle of the valve is tightly bound to the handle mounting hole by the clamping means is first. The purpose is to maintain a consistent state coupled to the.

In addition, the present invention for achieving the above object is a valve control device for selectively opening and closing the valve by using the power of the motor, a plurality of reduction gear group and the reduction gear group is assembled between the motor drive shaft and the valve drive shaft It is spoken so that it can be lifted to the final gear, and it is selectively rotated by connecting with the intermediate gear and the intermediate gear assembled so that the motor power can be selectively transmitted to the valve drive shaft according to the lifting position. And a drive gear of the valve driving thrust having a moving groove portion to have a deployment range of the pin, and a stopper member of a pin shape is installed on the moving groove portion of the drive gear so that the deployment angle of the valve can be limited to 90 °. The lower end is provided with a clamping means so that the handle extended to the valve shaft can be vibrated or manually opened and closed within the rotation range of the drive gear. It characterized in that hayeoseo provided with a handle mounting sphere integrally.

Hereinafter, the present invention described above will be described in detail with reference to embodiments of the accompanying drawings.

1 is a partial cutaway perspective view illustrating the overall configuration of the subject innovation, Figure 2 is a front view illustrating the operation of the subject innovation, the valve opening and closing control apparatus of the subject innovation, the motor 10 is The reduction gears 12 and 13 and the intermediate gear 14 between the upper support plate 1 to be installed and the lower support plate 2 having the tube fixing fastener 3 at the bottom thereof, and a connecting gear at the lower end of the intermediate gear. Each of the drive gears 20 selectively connected with the 16 is provided.

That is, a plurality of reduction gears 12 and 13 are connected to the motor drive shaft 11 so that power transmission can be selectively performed by the intermediate gear 14, and among them, the gear reduction shaft 13 of the outermost gear is connected to the motor driving shaft 11. The gear 14 is connected to each other, and the driving gear 20 is installed on the other side of the intermediate gear 14 again along the valve driving shaft 23, and is cut at an angle of 90 ° to the inner circumference of the driving gear 20. By forming the movable groove 21 to be regulated by the pin 22, the valve drive shaft 23 is configured to smoothly open and close the valve 5 within the restricted law in accordance with the drive of the motor 10. do.

On the other hand, the intermediate gear 14 connecting the reduction gear 13 and the drive gear 20 drives the power of the motor 10 by vertically moving the push shaft 17 in accordance with the vertical movement. In order to selectively transmit to the gear 20, the gearless portion 15 and the connecting gear 16 portion beneath the intermediate gear 14 have a predetermined width. The intermediate gear 14 includes the upper support plate 1. The coil spring 19 is inserted between the push button 18 exposed above the above, so that the usual push shaft 17 is kept up, thus driving the gear on the valve drive shaft 23. 20 is to receive the power of the motor 10 in engagement with the connecting gear 16 on the push shaft (17).

In addition, the connecting pins 22 for connecting the support plates 1 and 2 of the upper and lower parts are installed so as to be fitted to the moving groove 21 of the drive gear 20, and the handle is delivered to the lower end of the valve shaft 6. (7) allows the opening and closing operation of the drive gear 20 to be electrically or manually opened and closed, and a pair of left and right clamping pieces 24 are further provided on the lower end of the valve drive shaft 23 on which the drive gear 20 is installed. Install the handle mounting holes 25, but the handle 7 of the valve (5) inserted therein is installed so that it can be firmly fixed to the handle mounting holes 25 by the clamping means of various structures attached thereto. . Because the valve driving shaft 23 and the valve shaft 6 must be positioned on the same axis, the handle mounting holes 25 are rotated about the shaft by the rotational force of the valve driving shaft 23 and the valve shaft 6 is moved in accordance with the movement. This is because the handle (7) on the can be switched to the open or closed state.If there is a deviation in the assembly position of the handle, the opening and closing operation is not performed together with the mechanical wear due to the assembly tolerance. Serious problems are on the rise.

However, the power propulsion motor 10 used here is a bidirectional motor capable of forward and reverse rotation, and is configured such that power is soon cut off by a control circuit (not shown) when the motor 10 being overloaded is overloaded. Done.

Therefore, when power is applied while the valve 5 is opened as shown in FIG. 3 (a), the valve drive shaft 23 is rotated by the power of the motor 10 and the drive gear 20 is rotated. As shown in (b) of FIG. 3, it is rotated by 90 °, and the drive gear 20 to be rotated as such is no longer provided by the pin 22, which is a stopper means fixedly installed in the moving groove 21. As the rotation of the motor is left in an instant, the motor 10 is momentarily overloaded, and the power of the motor can be cut off immediately.

When the user selects the open mode MODE using the control unit (not shown) in the state where the valve 5 is opened as described above (when setting the rotation direction of the motor), as shown in FIG. Since the moving groove 21 is restricted by the pin 22, the rotation of the drive gear 20 is suppressed, and thus, an instantaneous overload is also generated, so the power passage that was connected to the motor 10 is soon shut off. Going back to.

In the case of an emergency situation in which the operation of the motor 10 is stopped due to the occurrence of a mechanical problem such as a fire, a power failure, or any other operation during the electric operation made up of such a series of repetitive motions, it is necessary to feel the need to shut the valve 5 urgently. When the push button 18, which is raised by the force of the spring 19, is pushed downward, the intermediate gear 14 on the push shaft 17 is lowered, which is configured at the lower end of the intermediate gear 14. The driving gear 20 engaged with the connecting gear 16 is separated from the connecting gear 16 to the intermediate gear 15 so that the valve driving shaft 23 can be idle. In this state, it is possible to simply close the open valve 5 by manually operating the handle 7 firmly inserted into the handle mounting hole 25.

As stated in the assembly of the belt shaft 6 handle 7 to the handle fitting portion 25 on the valve driving side 23 so that they can maintain the same axis, a pair of left and right clamping pieces 24 are idle at the tip as stated. It is most preferable in the fastening method that the structure is gradually narrowed from the left and right by the adjustment screw 26 possibly connected, but as shown in FIG. 5, both sides of the handle mounting hole 25 are shown.
