The present invention relates to a valve driving device of a hot water distributor for heating, and in particular, in a valve driving device of a hot water distributor for heating, the clutch, which is coupled to the rotary shaft of the driving motor and is formed inside the tooth formed along the inner circumferential surface of the manual knob, engages with the tooth in one direction. The present invention relates to a valve driving device for heating hot water dispenser having a plurality of ratchets formed with locking protrusions, in which a manual knob rotates together.

Furthermore, the present invention simplifies the construction by eliminating the spring that is inserted between the rotating shaft of the drive motor and the clutch in the valve driving apparatus of the conventional hot water distribution machine for heating, thereby reducing the number of parts and reducing the failure rate and the manufacturing process and It is to reduce the manufacturing cost.

In general, the heating system widely used in Korea until now is a boiler, a hot water distributor connected to the boiler to distribute and supply hot water to a plurality of rooms, and to return to the boiler, connected to the distribution supply pipes of the hot water distributor It consists of a hot water control valve for controlling the amount of hot water distributed to each room, and one temperature controller installed in one of the plurality of rooms, according to the set temperature set by the user to one temperature controller of the boiler and hot water circulation pump Operation was to be controlled.

However, the temperature control valve of the conventional hot water distribution device for boiler is installed in a state in which the driving motor for operating the on-off valve is laid down, so that the case width of the device must be widened due to the structure of increasing the plane, so that the interval between the hot water discharge pipes The increase in the occupied space occupied by the device increases the space utilization and there is a problem that it is difficult to select the installation space.

In addition, the valve is opened and closed separately by the manual knob and the driving motor, and the valve is opened and closed, which increases the number of parts required and the overall structure is very complicated, resulting in an increase in the failure rate and an increase in the manufacturing process and manufacturing cost, thereby reducing the competitiveness. It was called.

Therefore, in order to solve the above problems, the applicant has registered Utility Model Registration No. 366914, "Driver of the valve for heating hot water distributor."

Looking at the drive device of the pre-registered heating hot water distributor valve, the independent rotation to the rotary shaft of the drive motor is fixedly installed in a standing state of the case of any shape having a fastener for fastening with the opening and closing valve at the bottom It is impossible to engage with the clutch having a one-way locking jaw in the front.

In addition, a spring is inserted into the rotation shaft between the clutch and the drive motor to give the clutch a contraction and elastic movement force to its original position.

In addition, it is installed so that a part is exposed to the outside through the case, it is arranged to enable independent rotation on the rotation axis of the drive motor, and selectively correspond to the front of the one-way locking jaw of the clutch and the driven locking jaw to the inner side in the same manner Combined with the manual knob to integrally protrude.

In addition, it is configured to be connected to the manual knob and includes a rotational force transmission means for transmitting the rotational force of the manual knob and the drive motor to the valve, respectively.

Therefore, when the user operates the operation switch installed in the room, etc. to adjust the amount of hot water, the driving shaft is coupled to the rotating shaft and the clutch coupled thereto, so that the one-way locking jaw of the clutch is caught by the driven locking jaw and rotates with the manual knob.

However, the design of the pre-registration is such that the clutch coupled to the rotational shaft of the drive motor is positioned to the side, so that the clutch can be retracted and elastically moved to its original position by a spring so that the clutch can be caught by the clutch and the clutch of the manual knob. Since the elastic force is deteriorated due to continuous spring elasticity, the clutch cannot be pressed tightly, so there is play between the clutch and the manual knob, and thus the clutch rotation is not caught. There is a problem in that the manual knob is not rotated integrally to adjust the amount of hot water accurately.

On the other hand, the drive device of the pre-registered heating hot water distributor valve is coupled to the manual knob by combining the rotational force of the drive motor with the torque transmission means for transmitting to the valve is a disk-shaped cam integrally on the outer surface of the manual knob And a cam having a support bracket having a mounting groove on an upper surface thereof, and a pressure roller elastically in close contact with an outer circumferential surface of the cam in a state of being fitted into a mounting groove of a roller support portion having an insert portion integrally on a bottom surface thereof, and inserting the roller support portion. It is installed to be lifted up and down to the case in the state fitted to the part and the valve actuating opening is configured to open and close the valve to enable the expansion and contraction of the separation interval through the spring.

However, if the elastic force of the spring inserted between the insertion portion and the valve operating port which is the rotational force transmission means is greater than an appropriate level, the user does not maintain the state of adjusting the amount of hot water, and if the insertion portion is elevated by the elastic force of the spring, the pressure roller When the cam presses the outer circumferential surface of the cam, the driven locking jaw of the manual knob passes over the locking jaw of the clutch, and the manual knob rotates, thereby causing a malfunction of the on / off valve.

That is, the reason why the driven locking jaw of the manual knob passes over the locking jaw of the clutch is that the spring is located between the insertion port and the valve operation port because it rotates up and down corresponding to the front of the clutch. A malfunction may occur due to the repulsive force.

Therefore, it is necessary to periodically replace the spring in order to prevent the play from occurring due to the decrease in the elastic force of the spring that continuously presses the clutch between the driving motor and the clutch in the driving device of the valve for the heating hot water distributor. There is a weighted problem.

In addition, as the number of parts required to add elastic force to the clutch so that the clutch located on the side in close contact with the rotary shaft of the drive motor increases, the overall structure is very complicated, resulting in an increase in the failure rate and an increase in the manufacturing process and manufacturing cost. There is a problem that brings down the competitiveness.

As an improved design for solving the above problems, the object of the present invention is to omit the spring continuously continuously acting on the clutch coupled to the rotating shaft of the drive motor, and when it is built up inside the manual knob, it is in close contact with the elastic force and integrally It is to provide a drive device for a valve for heating hot water distributor having a ratchet formed on the clutch to rotate.

Therefore, the present invention prevents the play between the clutch and the manual knob due to the decrease in the elastic force of the spring, and the manual knob is forcibly rotated by the repulsive force of the spring located between the insertion portion of the rotational force transmission means and the valve operating port. This simplifies configuration and simplifies the number of components, reducing the failure rate and reducing the manufacturing process and manufacturing costs.

In order to achieve the above object, the present invention is a drive device for a valve for heating hot water distributor, which can open and close the on / off valve located at the bottom by automatic or manual operation, the driving device for the valve for heating hot water distributor is a driving motor. A clutch each having a plurality of ratchets formed in a diagonal direction along an edge to be combined with a rotational shaft of the to give an elastic force in one direction;

When the ratchet of the clutch is constructed as a mounting hole, it engages with the teeth formed along the inner circumferential surface of the mounting hole, characterized in that it rotates integrally with the manual knob.

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

1 is an exploded perspective view showing a clutch and a manual knob in the driving device of the valve for heating the hot water distributor according to the present invention.

The present invention, when the clutch (1) coupled to the rotary shaft (9) of the drive motor (2) is built in so that there is no play between the manual knob 11, it is in close contact by the elastic force to close the valve for hot water distributor It is to enable automatic opening and closing or manual operation.

Therefore, the clutch 1 coupled to the rotary shaft 9 of the drive motor 2 and rotated is installed in the mounting hole 8 of the manual knob 11 so that the body can be kept in close contact with the inner circumferential surface by elastic force. At the edge of 20, the ratchet 3 which is divided into quarters in the diagonal direction is integrally formed in order to give elastic force in one direction.

The ratchet 3 has a plurality of elastic pieces 6 vertically bent along the edge of the body 20 so that one end thereof protrudes from the side to form a gap 4 with the body 20 to impart an elastic force. Is formed.

In addition, the other end of the elastic piece (6) is formed integrally with the engaging projection (5) so as to mate with the teeth (7) of the manual knob 11 in one direction.

Therefore, the ratchet 3 is to form an elastic force to the elastic piece 6 is formed by the body 20 and the gap (4).

In addition, the manual knob 11 has a mounting hole (8) is formed in the center in the front so that the clutch (1) can be built in, the teeth 7 to engage with the ratchet (3) along the inner peripheral surface of the mounting hole (8). ) Is formed.

In addition, the cam 13 is integrally formed on the other side so as to pressurize the pressure roller 14 when the manual knob 11 is rotated, as well as the concave-convex shape to facilitate manual operation at the edge of the manual knob 11. It has a structure.

Figure 2 is a plan view showing a coupling state of the clutch and the manual knob in the drive device of the valve for heating hot water dispenser of the present invention.

When the clutch 1 is inserted into the mounting hole 8 of the manual knob 11, the ratchet 3 is in close contact with the inner circumferential surface of the manual knob 11, and the elastic piece 6 of the ratchet 3 is When the elastic force is always provided in the outward direction, the locking projection 5 located at the end of the elastic piece 6 is always in close contact with the teeth 7 and rotates integrally.

Ratchet (3) consisting of the elastic piece (6) and the engaging projection (5) on the clutch (1) is a manual knob tightly because the elastic force is not degraded by continuous elastic operation, unlike the spring 16, which is a conventional ballistic member The state of engagement with the tooth 7 of (11) is to be closely interfered so that play does not occur between the manual knob 11 and the clutch 1.

Figure 3 is an exploded perspective view showing the separation of the drive device of the valve for the hot water distributor designed.

The driving device of the valve for heating hot water dispenser is coupled to the rotary shaft 9 of the drive motor 2 so as not to rotate independently and has a clutch 1 having a plurality of ratchets 3 formed around the edge thereof.

Therefore, when the clutch 1 is installed in the manual knob 11 in which the mounting hole 8 is formed so as to enable independent rotation in the rotation shaft 9 of the drive motor 2, one direction is formed around the edge of the clutch 1. The latching projections 5 of the ratchet 3 formed as such are engaged with the teeth 7 formed on the inner circumferential surface of the manual knob 11.

In addition, the manual knob 11 is configured to be connected, the rotational force transmission means 21 for transmitting the rotational force of the drive motor 2 to the valve (V) is provided.

The rotational force transmission means 21 has a circular cam 13 integrally formed on the outer surface of the manual knob 11 and a support bracket 17 having a mounting groove 15 on the upper surface thereof, and inserted into the bottom surface. A roller support portion 12 integrally provided with a portion 18, a pressure roller 14 elastically in close contact with the outer circumferential surface of the cam 13 in a state of being fitted into the mounting groove 15 of the roller support portion 12, and It is composed of a valve actuating opening 19 is installed so as to be elevated in the case (C) in the state fitted to the insertion portion 18 of the roller support 12 and coupled to expand and contract the separation interval through the spring (16). .

Figure 4 is a cross-sectional view showing a coupling state of the driving device of the valve for the hot water distribution valve according to the present invention, Figure 5 is a front view illustrating the assembled state of the drive device of the valve for hot water distribution valve according to the present invention.

The driving device of the valve for heating hot water distributor according to the present invention is installed at each of the on / off valves (V) installed in the discharge pipe of the hot water distributor using the fastener (J) at the bottom of the case (C), It is provided in a controller attached to a certain position such as indoors so that the switch of the corresponding open / close valve (V) can be turned on and off at a certain place.

First, FIG. 5 is a view showing the maximum opening state of the valve V. The valve opening guide protrusions 10 and 10 'are in contact with the valve opening limit switch 23 installed inside the case C. .

In this state, when the driving motor 2 is driven by operating an operation switch installed in a room or the like to adjust the amount of hot water, the rotary shaft 9 and the clutch 1 coupled thereto are rotated while the elastic piece (1) moves in one direction to the clutch (1). 6) and the plurality of ratchets (3) formed by the locking projection (5) is rotated together when the cogwheel 7 formed on the inner peripheral surface of the mounting hole (8) and the locking projection (5) the manual knob (11).

In addition, when the manual knob 11 is rotated, the cam 13 integrally formed with the manual knob 11 is rotated to press the pressure roller 14 downward, and thus the roller support 12 is a spring 16. ) By pressing the valve actuation port 19 while the valve actuation port 19 presses the actuation rod 24 in the valve V downward again to close the valve V. The closing degree is determined according to the rotation range of 11) and the descending degree of the valve operating port 19 proportional thereto.

In the above, the role of the spring 16 is that the pressure roller 14 and the valve actuating mechanism 19 are elastically in contact with the cam 13 and the operating rod 24 even when the pressing force of the cam 13 is released. The state can be maintained to prevent play.

On the other hand, even though the elastic force of the spring 16 is relatively too large, the ratchet 3 of the clutch 1 is forced even if the pressure roller 14 is raised and lowered by the repulsive force to force the pressing force of the cam 13 as conventionally. Since there is interference between the teeth 7 formed on the inner circumferential surface of the manual knob 11 by the elastic force so as not to rotate arbitrarily, there is no play between the clutches 1 built on the manual knob 11.

In addition, when the driving motor 2 of the driving device of the valve for heating hot water dispenser fails to operate due to a sudden power failure, the manual knob 11 partially exposed through the exposure hole C ′ of the case C may be used. When forced to rotate is to operate the same as the drive motor (2) to open and close the valve (V).

As described above, when the manual knob 11 also rotates when the driving motor 2 is driven, the degree of opening and closing can be visually checked from the outside through the exposure hole C ', thereby ensuring safety in maintenance. It becomes possible.

In addition, different colors are painted around the edge of the manual knob 11 to visually check the opening and closing state of the valve V. FIG.

For example, as shown in FIG. 5, the open state is displayed in red, and on the contrary, the cam part is lowered and the closed state is displayed in blue, so that the user can easily identify it.

As described above, in the drive device of the valve for heating hot water dispenser of the present invention, when the clutch integrally formed with a plurality of ratchets is provided inside the manual knob to impart an elastic force, the latch is engaged with the teeth by the elastic force so that the play occurs. Not only can close and close the on-off valve by closely contacting the ratchet, as well as the ratchet has the effect that can be used semi-permanently because there is no elastic force deterioration due to the spring action.

In addition, as described above, the driving device of the valve for heating hot water dispenser is that the clutch formed with the ratchet is built up inside the manual knob and interferes with the elastic force. The rotation is prevented from malfunctioning has the effect of providing an accurate amount of hot water.

Therefore, the present invention omits the spring which is inserted between the clutch coupled with the rotating shaft of the drive motor and the elastic member for imparting elastic movement force to the clutch, and imparts elastic force in the clutch itself. By forming the simplification of the components in accordance with the simplified configuration, there is an effect of reducing the failure rate and manufacturing process and manufacturing cost.
