Description

VALVE DRIVING DEVICE

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a valve driving apparatus, and more particularly, to a valve driving apparatus capable of precisely and stably adjusting opening amount of a valve.

Valves are installed in fluid lines to control the flow rate of various fluids. The valve is manually controlled by the user, but is automatically controlled in a system in which the supply of fluid is remotely controlled.

For example, the operation of the hot water control valve for controlling the supply amount of the hot water in the automatic control heating system is automatically controlled. To this end, the hot water control valve is combined with a valve actuating actuator which operates according to the temperature of the room where the heating is performed or the temperature of the hot water recovered after heating the room, thereby automatically controlling the opening amount of the hot water control valve.

An example of such a valve actuating actuator is disclosed in Korean Utility Model Registration No. 368370 (registered on November 10, 2004). The valve actuating actuator disclosed in the above publication includes a lower body having a predetermined space, a ring body vertically movably coupled to an upper portion of the lower body, a case body formed of a cap coupled to an upper portion of the ring body, A plurality of reduction gears connected to the motor to reduce the rotation of the motor, a rotation shaft installed to be reduced in rotation by the reduction gears, a screw disposed in a predetermined space of the lower body and rotated in place, An actuating member vertically movable in a predetermined space in a predetermined space of the lower body by rotation of the screw to control an opening and closing operation of the valve and a speed reducer provided with magnets and magnets arranged at regular intervals in any one of the reduction gears The time, the number of revolutions, and the direction of rotation between the magnets are checked by a hall sensor and converted into an electronic signal, It calculates a control value and the drive value by its call includes a microcomputer for controlling the motor.

In the conventional valve actuating actuator as described above, since the actuating member for controlling the opening and closing operation of the valve vertically moves by the action of the screw, the packing which vertically moves the valve opening and closing the valve is vertically moved. Excessive pressurization of the packing, or less pressing of the packing. If the operating body excessively pressurizes the packing, the valve may be damaged. If the operating body presses the packing less, the flow path of the valve may not be completely closed. Even if such problems do not occur at the initial stage of the actuator installation, repeated use of the actuator may make it difficult to adjust the opening amount of the valve due to wear of various parts.

Further, the conventional valve actuating actuator has a complicated mechanism for operating the actuating body. That is, in order to convert the rotational force of the motor into the linear movement force of the actuating body, a plurality of reduction gears, a rotary shaft and a screw are required, and the screw and the actuating body must be coupled to each other. Therefore, in the conventional valve actuating actuator, the number of parts is large, the coupling relation between the parts is complicated, and manufacturing tolerances and assembly tolerances of the respective components are precisely controlled, so that the manufacturing process is complicated and the manufacturing cost is high.

The first cover gear 181 can engage with the connecting gear 202 of the connecting member 200. Accordingly, as the drive cover member 180 rotates, the valve driving member 170 can be operated up and down.

Referring to Fig. 3, the inner shape of the drive cover member 180 will be described. Inside the drive cover member 180, a space opened to the upper side is provided, and a protrusion guide 185 is formed in the inner lower side. The protruding guide 185 is a portion where the roller 172 of the valve driving member 170 contacts and the roller 172 moves relative to the protruding guide 185 when the driving cover member 180 rotates. The protrusion guide 185 is formed to surround the through hole 187 formed in the inner bottom surface of the drive cover member 180 and has a different height in the direction of wrapping the through hole 187 in the inner lower surface, .

That is, the protruding guide 185 starts on the same plane as the inner lower surface, and has a shape protruding upward from the inner lower surface along the perimeter of the through hole 187 to a distance of more than half the distance in the upward direction. The section in which the height of the protruding guide 185 is increased is defined as the rising section 185a. And a predetermined groove may be formed at a position where the height of the protrusion guide 185 is the highest. The roller 172 moving along the protrusion guide 185 may be inserted into the groove for a while. A section in which the predetermined groove is formed is defined as a vertex section 185b. In the vertex section 185b, the protruding height of the protruding guide 185 is suddenly lowered in the advancing direction of the roller 172. In this way, the section in which the height of the protruding guide 185 is sharply lowered is defined as the falling section 185c.

The lifting section 185c may include at least about 25% of the entire section, and the remaining section may be a section parallel to the inner bottom surface of the driving cover member 180. [

As the protrusion guide 185 is formed, the roller 172 can be rotated and moved along each section of the upper surface of the protrusion guide 185. That is, the roller 172, which is in contact with the upper surface of the protrusion guide 185, moves up and down along the rising section 185a, peak section 185b and falling section 185c of the protrusion guide 185 as the drive cover member 180 rotates. And can be raised or lowered while moving relative to each other. In this way, the valve 172 can be moved up or down along the protrusion guide 185 to move the valve driving member 170 up or down to operate the valve.

The valve driving member 170 is urged downward by the urging spring 179. The pressure spring 179 is configured such that one end of the pressure spring 179 is in contact with the adjustment handle 130 and the other end is in contact with the roller mounting portion 174 of the valve driving member 170, As shown in Fig. When the drive cover member 180 rotates due to the action of the pressure spring 179, the roller 172 can smoothly move upward and downward relative to the protrusion guide 185 while being in close contact with the protrusion guide 185.

The clutch 190 has a structure having a through hole to enclose the valve driving member 170. The clutch 190 includes a clutch body 191 movably disposed inside the housing 105 so as to press the drive gear 162 and a clutch body 191 protruding from one side of the clutch body 191, As shown in FIG.

The other side of the clutch body 191 may be disposed in proximity to or in contact with the driving gear 162 of the driving unit 160. The clutch 190 can be operated to move the clutch knob 192 in the protruding direction. When the user presses the clutch knob 192 inward of the housing 105, the clutch body 191 pushes the driving gear 162. At this time, the driving gear 162 of the driving portion 160 and the driving cover member 180 May be spaced apart from each other.

The connecting member 200 is disposed on one side of the valve driving member 170. As described above, the connecting member 200 has a shape of a bar having a length in one direction, and can rotate about the longitudinal direction as a central axis. The connection member 200 can be supported by the upper housing 110 and the lower housing 120 so that the upper and lower parts can be rotated by the coupling of the upper housing 110 and the lower housing 120, respectively.

The upper part of the connecting gear 202 is engaged with the handle gear 132 of the adjustment handle 130 and the lower part is arranged to engage with the first cover gear 181 of the drive cover member 180. The connecting member 200 serves to connect the adjusting handle 130 and the driving cover member 180 so that the adjusting handle 130 and the driving cover member 180 can rotate at the same time.

The first to third sensors 212, 214 and 216 are disposed on one side of the driving unit 160 and are provided to sense the rotation of the driving cover member 180. That is, the first to third sensors 212, 214, and 216 sense the movement of the drive cover member 180, respectively, and sense whether the valve driving apparatus 100 is operating normally. The first to third sensors 212, 214 and 216 detect the rotation of the drive cover member 180 at predetermined time intervals. The result detected by the first to third sensors 212, 214 and 216 is If not, the valve driving apparatus 100 can be regarded as not normally operating, and in this case, the valve driving apparatus 100 can be controlled so that the valve is immediately blocked.

The valve regulating member 220 is disposed to be inserted at least partly into the regulating hole 176 formed in the valve driving member 170, and a valve can be coupled to the lower portion. The valve control member 220 and the valve coupled to the lower portion of the valve control member 220 can simultaneously move up and down as the valve driving member 170 is moved up and down.

2, the valve regulating member 220 has a predetermined length in one direction and may have a cylindrical shape. A coupling thread 224 is formed on the outer circumferential surface of this valve regulating member 220 and the engaging thread 224 can be engaged with the adjusting thread 178 of the valve driving member 170.

A wrench groove 222 may be formed at an upper portion of the valve regulating member 220, and a valve coupling hole 226 may be formed at a lower portion thereof. At this time, the wrench groove 222 and the valve coupling hole 226 are not connected to each other inside the valve adjusting member 220, but may be formed at the upper and lower portions of the valve adjusting member 220, respectively.

That is, the wrench groove 222 is formed to have a predetermined depth on the upper surface of the valve regulating member 220, and may have a shape corresponding to the shape of the wrench 230 so that the wrench 230 is inserted. The wrench 230 may have a hexagonal shape so as to correspond to the shape of the hexagonal wrench 230. In this embodiment, The valve regulating member 220 is screwed in the adjusting hole 176 as the wrench 230 is inserted and rotated in the wrench groove 222 so that the valve regulating member 220 is moved in the valve driving member 170, In the vertical direction.

4 is a view for explaining the operation of the valve driving apparatus according to the first embodiment of the present invention.

Hereinafter, the operation of the valve driving apparatus 100 according to the present embodiment will be described with reference to FIG.

The driving unit 160 is operated to rotate the driving gear 162 to open the valve by an externally applied power source. The drive cover member 180 is rotated by the second cover gear 183 engaged with the drive gear 162 as the drive gear 162 rotates. When the drive cover member 180 rotates in this manner, the roller 172 of the valve drive member 170 located inside the drive cover member 180 relatively moves along the protrusion guide 185, 170 are raised or lowered.

As the drive cover member 180 rotates, the first cover gear 181 of the drive cover member 180 is engaged with the connection gear 202 to rotate the connection member 200, (132) is engaged with the adjustment knob (130). That is, according to the rotation of the adjustment handle 130, the user can confirm that the valve is opened or blocked.

The valve driving member 170 moves in the ascending direction while the roller 172 of the valve driving member 170 moves along the rising section 185a of the protrusion guide 185. [ When the roller 172 is positioned at the vertex section 185b of the protrusion guide 185, the valve driving member 170 is in the maximally raised state, and the valve is in the open state. And the valve driving member 170 moves in the descending direction while the roller 172 moves along the falling section 185c of the protrusion guide 185. [ Here, since the descending section 185c has a section that is shorter than the ascending section 185a, the moving speed of the valve driving member 170 may be faster than the moving speed of the valve driving member 170 when descending.

The valve driving member 170 and the valve connected to the valve driving member 170 may be opened or closed by moving the valve driving member 170 upward or downward by driving the driving unit 160. In this case, Each of which may be manufactured according to a predetermined standard. That is, in a state where the valve and the valve driving member 170 are engaged, the valve engagement member 140 is coupled to the pipe provided with the valve, and the valve driving member 170 is driven to check whether the valve normally blocks the pipe. , The valve may not normally operate.

This is because the coupling between the valve and the valve driving member 170 may be separated by a predetermined distance from the position at which the valve is to be blocked. Therefore, the user may adjust the blocking position of the valve by inserting the wrench 230 through the handle hole 136 of the valve driving device to rotate the valve adjusting member 220.

Further, in the present embodiment, the valve driving apparatus 100 can be operated manually. The user can hold the handle bar 134 and rotate the adjustment handle 130 to open and close the valve. At this time, the adjustment handle 130 may be rotated in both directions, and may be rotated only in one direction by a motor included in the driving unit 160. [ In this embodiment, as the adjusting knob 130 rotates in the clockwise direction as shown in Fig. 4, the opening and closing operation of the valve can be performed.

When the adjusting knob 130 rotates clockwise, the connecting gear 202 engaged with the knob gear 132 formed on the adjusting knob 130 rotates and the first cover gear 181 engaged with the connecting gear 202 The drive cover member 180 is rotated by the rotation. At this time, the drive cover member 180 is rotated clockwise.

As the drive cover member 180 rotates in the clockwise direction, the roller 172 moves along the upper portion of the protrusion guide 185 and the valve driving member 170 is moved up and down by the shape of the protrusion guide 185 .

That is, when the arrow shape formed on the handle bar 134 of the adjustment knob 130 is positioned at the "Close" position, the roller 172 is positioned between the falling section 185c of the projection guide 185 and the rising section 185a And the valve driving member 170 is located in a state where the valve driving member 170 is moved downward. As a result, the valve is shut off.

When the adjustment handle 130 rotates and the arrow shape formed on the handle bar 134 is positioned at the "Open" position, the roller 172 is located at the apex section 185b of the protrusion guide 185, The member 170 is moved to the uppermost position, and the valve is opened.

When the adjusting knob 130 rotates so that the shape formed on the handle bar 134 is located at a position where a number between "Close" and "Open" is formed, the roller 172 is moved upward 185a. As a result, the valve is partially open. At this time, the greater the number, the greater the degree of opening of the valve.

When the adjustment handle 130 rotates and the shape of the arrow formed on the handle bar 134 is located at a position where there is no indication between "Open" and "Close", the adjustment handle 130 rotates rapidly and the handle bar 134 Quot; Close "to close the valve. This is because when the roller 172 is located on the descent section 185c beyond the correction section 185b of the protrusion guide 185 and the slope of the descent section 185c is relatively steep compared to the ascending section 185a Since the roller 172 is moved downward along the descending section 185c rapidly.

5 is a view for explaining the clutch operation of the valve driving apparatus according to the first embodiment of the present invention. And FIG. 6 is a view illustrating the inside of a driving unit of the valve driving apparatus according to the first embodiment of the present invention.

Referring to FIG. 5, the clutch 190 is partially exposed to the outside between the upper housing 110 and the lower housing 120. The clutch 190 can move inward of the valve driving apparatus 100, which is the direction in which the driving unit 160 is disposed.
