Hereinafter, a flow control valve driving apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 to 4, the flow rate control valve drive apparatus according to the embodiment of the present invention includes a unidirectional rotary motor 11, a main shaft and a longitudinal gear 20 (20a) in the form of a bevel gear, and a predetermined valve drive plunger 30 may be provided in a compact body case 10 and a body cover 10a.

The rotation motor 11 is driven in a unidirectional direction when a predetermined power is applied. The rotation motor 11 is not only economical because it consumes less electric power than a bi-directional motor, and is light and small in size. It is very useful in achieving the technical effect.

The main shaft gear 20 and the vertical shaft gear 20a can be said to be capable of converting the drive state of the rotary motor 11 alternately between forward rotation and reverse rotation, respectively. The main shaft gear 20 and the longitudinal shaft gear 20a may be various types of bevel gears.

The main spindle gear 20 according to the embodiment of the present invention is mounted on the shaft of the rotation motor 11 and is rotated so as to follow the driving state of the rotation motor 11 rotating unidirectionally.

The vertical axis gear 20a is suspended from the inner ceiling of the body cover 10a. For example, a hole is formed at a predetermined position on the upper end of the main body cover 10a, and a predetermined vertical axis 20b is provided in the hole. Then, the armature gear 20a is mounted on the vertical axis 20b Can be carried out by the following methods.

At this time, the vertical axis 20b is installed in the vertical direction with respect to the shaft of the main shaft gear 20 or the rotation motor 11, and the vertical axis gear 20b is engaged with the main shaft gear 20 in the vertical direction So as to maintain the state.

In addition, the vertical axis gear 20a is configured so that the unidirectional rotation of the main shaft gear 20 by the rotation motor 11 can be converted into normal rotation and reverse rotation, respectively.

For example, the main shaft gear 20 is provided with first and second teeth 21 and 22, which are staggered to each other along opposite ends of the body, 20a may be reversed in forward rotation and reverse rotation every time the first teeth 21 and the second teeth 22 of the main shaft gear 20 are rotated by the driving force of the rotary motor 11 Or a combination of a plurality of gears having at least two gears.

Here, the longitudinal axis gear 20a meshes with the second tooth row 22 of the main shaft gear 20 and rotates when the direction of rotation of the main shaft gear 20 in engagement with the first tooth row 21 is referred to as normal rotation The direction can be called reverse rotation.

That is, the vertical axis gear 20a is rotated clockwise or counterclockwise every time it is engaged with the first and second teeth 21 and 22 formed around the body of the main shaft gear 20 , And the unidirectional rotation by the rotation motor (11) can be switched between forward rotation and reverse rotation.

The valve driving plunger 30 is interlocked with the normal and reverse rotation of the vertical axis gear 20a and is capable of lifting and lowering movement in the body case 10 up and down. That is, the valve driving plunger 30 operates the predetermined opening / closing plunger 51 of the valve body 50, which is engaged and used by a coupling nut 13 provided on the bottom outer surface of the lower end portion of the main body case 10 And corresponds to a series of linear reciprocating motion modules provided in the main body case 10.

More specifically, the valve driving plunger 30 is configured such that one side of the valve driving plunger 30 is engaged with the longitudinal gear 20a and the other side of the valve driving plunger 30 is screwed into a predetermined screw bar 12 provided in the main body case 10, As shown in FIG.

The through hole of the screw bar 12 is inserted into the body case 10 from the outside so as to be connected to the opening and closing plunger 51 of the valve body 50 which is coupled by the coupling nut 13 .

The main structure of the valve driving plunger 30 will be described in detail by dividing it into the flying gear 31, the lifting member 32 and the grounding end 33 in detail.

The flying gear 31 is installed so as to engage with the vertical axis gear 20a for switching unidirectional rotation of the rotary motor 11 to normal rotation and reverse rotation.

Particularly, the flying gear 31 is suspended from the inner ceiling of the main cover 10a like the longitudinal gear 31, and is interlocked with forward rotation or reverse rotation of the longitudinal gear 31, Thereby transmitting the rotational force.

The elevating member 32 is provided so as to be movable up or down according to the rotational direction of the flying gear 31. One end of the elevating member 32 is inserted and fixed to the flying gear 31, Can be embodied in the screw bar (12), and can be variously combined.

At this time, the flying gear 31 has a link hole 31a penetrating through the center thereof so that one end of the lifting member 32 can be engaged. In particular, it is preferable that the inner circumferential surface of the link hole 31a is provided with an indentation having a predetermined height in the longitudinal direction so that a predetermined rotational force can be applied to the elevating member 32. [

On the other hand, on the outer surface of the elevating member 32 inserted into the screw bar 12, there is formed a screw thread 32a which is partially engaged with a predetermined screw groove formed on the inner circumferential surface of the through hole of the screw bar 12 .

The screw thread 32a of the elevating member 32 is screwed into the thread groove in the screw bar 12 when a predetermined rotational force is applied to the elevating member 32 from the flying gear 13 32a are moved, ultimately, the elevating member 32 is caused to move up or down to cause the elevating operation.

The grounding end 33 may be pressed or lifted at a predetermined interval in contact with the opening / closing plunger 51 in the valve body 50 in accordance with the operating direction of the lifting member 32 moving up or down. It is a role to play.

The grounding end 33 may be formed integrally with the end of the elevating member 32 or may be formed in a form different from the elevating member 32.

The ground terminal 33 provided separately from the elevating member 32 may be provided with a predetermined overload spring 34 between the elevating member 32 and the ground terminal 33 .

In the case of the overload spring 34, the up-and-down clearance of the lifting member 32 can be improved by effectively compensating for the up-and-down motion of the lifting member 32, which may be excessive or somewhat lacking, And a technical effect such as allowing a somewhat generous gain is obtained.

Above all, the overload spring 34 together with the elevating member 32 applying the screw method remarkably improves the operational noise for driving the opening / closing plunger 51 for controlling the flow rate in the valve body 50 In addition, it also obtains the technical effect of improving the durability by eliminating vibration and impact, increasing the service life due to failure.

The flying gear 31 may be connected to a dial adjuster 35 for controlling the flow rate of the valve body 50.

3 to 5, the dial adjuster 35 may be provided outside the upper end of the main cover 10a and may be connected to the flying gear 31, for example.

The dial adjuster 35 may be the same as a kind of setting means for finely adjusting the flow rate of the valve body 50.

The flow rate control valve driving apparatus according to the embodiment of the present invention may basically have a limited flow rate control range of the valve body 50 according to the setting state of the dial regulator 35, It is possible to finely control the flow rate of the valve body 50 by controlling the opening and closing plunger 51 of the valve body 50 with precision only by unidirectional rotation of the rotary motor 11.

For example, a micro switch (40) for automatically controlling the power applied to the rotary motor (11) is further provided.

At this time, the micro switch 40 programs the power supply of the rotary motor 11 according to a predetermined pattern according to the rotation angle of the vertical axis gear 20a and the degree of lift of the valve driving plunger 30, And the like.

In addition, the micro switch 40 may further include a predetermined operation lamp 41 that can visually identify the operating state of the user.

It is preferable that the operation lamp 41 is applied in the form of an LED or the like so that the user can intuitively grasp the operation state of the flow rate control valve driving apparatus according to the embodiment of the present invention.
