Description

Drain valve control device
Technical Field
The present invention relates to a drain valve control device, and more particularly, to a drain valve control device that controls an output clutch mechanism by a brake mechanism, wherein a driving force of a driving source is transmitted to a valve element via the output clutch mechanism.
Background
Conventionally, as shown in fig. 9, there is a drain valve control device including a drive source 2X, an output clutch mechanism 3X, a valve element 8X, a linkage mechanism 41X, and a brake mechanism 42X, wherein the output clutch mechanism 3X includes a clutch mechanism and a planetary gear mechanism 32X, and the brake mechanism 42X includes a brake member 421X rotatable about a first axis, a transition member 422X rotatable about a second axis parallel to the first axis, and a return elastic member 423X. The driving force of the driving source 2X is transmitted to the valve body 8X via the clutch mechanism and the planetary gear mechanism 32X, and the driving force of the driving source 2X actuates the linkage mechanism 41X to apply force to the braking member 421X so that the engagement portion 42131X of the braking member 421X engages with the engaged portion 42211X of the transition member 422X driven by the planetary gear mechanism 32X (specifically, the ring gear of the planetary gear mechanism 32X), and the return elastic member 423X applies force to the braking member 421X in a direction to release the engagement between the engagement portion 42131X of the braking member 421X and the engaged portion 42211X of the transition member 422X.
In the above-described drain valve control device, in order to operate the valve body 8X, it is necessary to lock the ring gear of the planetary gear mechanism 32X with the transition member 422X, that is, to overcome the force transmitted from the ring gear of the planetary gear mechanism 32X to the transition member 422X to rotate the brake member 421X and release the engagement state between the engagement portion 42131X of the brake member 421X and the engaged portion 42211X of the transition member 422X.
Conventionally, in the above-described drain valve control device, in order to reliably maintain the engagement state between the engagement portion 42131X of the brake member 421X and the engaged portion 42211X of the transition member 422X so as not to disengage the two, the force applied to the brake member 421X by the link mechanism 41X is often set to be large, however, this is disadvantageous in terms of cost control, and abrasion is easily generated when the engagement portion 42131X of the brake member 421X and the engaged portion 42211X of the transition member 422X are engaged with each other, resulting in a reduction in the service life of the drain valve control device.

The pulling member 7 is a wire, one end of the pulling member 7 is engaged with the rotary output member 6, for example, and the other end of the pulling member 7 is connected to the valve body 8.
< operation of drain valve control device >
When the valve body 8 is in the initial position, the switching portion 511 of the switching stopper rod 51 engages the transition wheel 312 with the clutch wheel 311 against the biasing force of the biasing member 52.
In the above state, when the motor 2 is supplied with power, the driving force of the motor 2 is transmitted to the first portion of the linkage 41 via the transition gear, for example, to rotate the first portion at a high speed, whereby the second portion rotates by magnetic induction, and the brake member 421 is rotated, so that the engagement portion 42131 of the brake member 421 contacts the engaged portion 42211 of the transition member 422 (at this time, the first portion is in an idling state), and the transition member 422 is prevented from rotating, and the ring gear 324 of the output clutch 3 is prevented from rotating.
Meanwhile, the driving force of the motor 2 is transmitted to the transition wheel portion 312 via the clutch wheel 311 and then to the planetary gear 322 engaged with the sun gear portion 321, and at this time, the rotation of the ring gear 324 of the output clutch mechanism 3 is stopped, and therefore the planetary carrier 323 rotates, thereby rotating the transition gear TG engaged with the pinion gear portion 32311 of the planetary carrier 323, and further rotating the rotary output member 6 engaged with the transition gear TG, and the pulling means 7 is wound around the pulley portion 62 of the rotary output member 6, so that the valve element 8 is driven and displaced to the operating position, and the valve is opened.
When the valve body 8 is driven and displaced to the operating position, the switching portion 511 of the switching stopper rod 51 displaces the transition wheel portion 312 from the position where it engages with the clutch wheel 311 to the position where it is separated from the clutch wheel 32, whereby the driving force of the motor 2 is no longer transmitted to the valve body 8.
On the other hand, when the spool 8 is driven and displaced to the operating position, the stopper 512 abuts against the locking piece 31222 of the transition wheel 312 to restrict the transition wheel 312 from reversing, the driving force of the motor 2 is continuously transmitted to the first portion of the linkage 41, the second portion is magnetically and forcefully applied to the engagement portion 42131 of the brake member 421 to continuously contact the engaged portion 42211, the transition member 422 is prevented from rotating, and the ring gear 324 of the output clutch 3 is prevented from rotating, whereby the carrier 323 can be locked, and the spool 8, the pulling member 7, and the rotary output member 6 can be held in the state when the spool 8 is in the operating position.
When the power supply to the motor 2 is stopped, the valve element 8 starts to return to the initial position by the return force provided by itself, and at this time, the first portion of the linkage mechanism 41 stops rotating, and the magnetic induction force between the first portion and the second portion disappears, so that the brake member 421 releases the restraint on the transition member 422 by the return elastic member 423 of the brake mechanism 42, and the ring gear 324 of the output clutch mechanism 3 is in a freely rotatable state, whereby the valve element 8 returns to the initial position by the return force, and the valve is in a closed state.
According to the drain valve control device of the present embodiment, since the force applied by the engaged portion 42211 to the engaged portion 42131 passes through the first axis of the brake member 421 in a state in which the engaged portion 42131 of the brake member 421 is engaged with the engaged portion 42211 of the transition member 422, the brake member 421 is not rotated regardless of the amount of the force, that is, the force applied to the brake member 421 by the interlocking mechanism 41 does not need to be set to be large in order to resist the force, and even if a small force is applied to the brake member 421, the engaged state between the brake member 421 and the transition member 422 can be maintained.
Further, according to the drain valve control apparatus of the present embodiment, since the force applied to the brake member 421 by the link mechanism 41 does not need to be set to be large, the magnetic induction force between the first portion and the second portion of the link mechanism 41 can be set to be small, whereby the amount of the magnetic material used in the first portion can be reduced, further the load and the size of the return elastic member can be reduced, the cost can be reduced, and the size of the return elastic member does not need to be changed due to the increase of the load of the motor 2, and the versatility of the product can be improved.
Further, according to the drain valve control device of the present embodiment, the sector gear portion 4212 and the reverse extension portion 4213 are provided on both radial sides of the shaft portion 4211, and therefore, the rotation balance of the brake member 421 is ensured, and the stability of the engagement of the brake member 421 and the transition member 422 is improved.
Further, according to the drain valve control device of the present embodiment, since the transition member 422 includes the weight 4223, when the power of the motor 2 is cut off and the engagement between the brake member 421 and the transition member 422 is released, the transition member 422 can be smoothly rotated, and therefore, the valve body 8 having a interlocked relation with the transition member 422 can be smoothly operated.
Further, according to the drain valve control device of the present embodiment, in a state in which the engagement portion 42131 is engaged with the engaged portion 42211, the engaged portion 42211 biases the engagement portion 42131 toward the first axis, and therefore, the radial dimension of the brake member 421 is facilitated to be reduced, and the device as a whole is miniaturized.
Further, according to the drain valve control device of the present embodiment, when the valve element 8 is driven and displaced from the initial position to the operation position, the operation of the transition wheel 312 is controlled by only one member, i.e., the switching stopper rod 51 integrally provided with the switching portion 511 and the stopper portion 512, so that the driving force of the motor 2 is not transmitted to the valve element 8 any more and the valve element 8 and the rotary output member 6 are maintained in the state when the valve element 8 is in the operation position.
Further, according to the drain valve control device of the present embodiment, the engagement claws 31221 are provided on the outer peripheral edge of the disk-shaped portion 3122 of the transition wheel portion 312, which contributes to reducing the impact force received by the engagement claws 31221 when engaging with the clutch wheel 311, and to delaying the wear of the engagement claws 31221, thereby prolonging the service life of the transition wheel portion 312.
Further, according to the drain valve control device of the present embodiment, the locking piece 31222 is provided on the outer peripheral edge of the disk portion 3122 of the transition wheel portion 312, so that the impact force received by the locking piece 31222 when locking with the stopper portion 512 of the switching stopper rod 51 is reduced, and the wear of the locking piece 31222 is delayed, thereby prolonging the service life of the transition wheel portion 312.
Further, according to the drain valve control device of the present embodiment, by forming the locking piece 31222 to protrude toward the opposite side to the clutch wheel 311, the stopper portion 512 of the switching stopper rod 51 is easily locked with the locking piece 31222 when the valve body 8 is displaced to the operation position.
Further, according to the drain valve control device of the present embodiment, since the urging member 52 is a compression coil spring provided between the clutch wheel 311 and the transition wheel portion 312, the urging member has a simple structure, contributing to a reduction in manufacturing cost.
The invention has been described above by way of example with reference to the accompanying drawings, it being apparent that the invention is not limited to the embodiments described above.
For example, in the above embodiment, the force applied to the engaging portion 42131 by the engaged portion 42211 passes through the first axis in the state where the engaging portion 42131 is engaged with the engaged portion 42211, but the force applied to the engaging portion 42131 by the engaged portion 42211 passes through the shaft portion 4211 of the brake member 421 in the state where the engaging portion 42131 is engaged with the engaged portion 42211.
In the above embodiment, the driving source is a motor, but the present invention is not limited thereto, and a linear actuator or the like may be used as the driving source according to circumstances.
