Description

Electronic timer device for ball valve shutoff {The Digital Timer use of the valve}

The present invention relates to a timer device invented to close a ball valve after a set time, and in particular, to be effectively used for various ball valves such as gas, oil, chemicals, etc., and piping or time control.

The timer device invented for controlling the time on such ball valves is related to the improvement of the means and peripheral parts for eliminating some parts of the machine timer of 0310503 filed by the present inventor and registered in 2001. The user wants to control the ball valve precisely with simple operation and low current.

1 and 2 are internal structural views explaining the above patent, a main shaft 152 having a pitch of 90 degrees removed, a time stop lever 183, a spring spring 153, and a ball valve forcibly leaving the gear. Ball clutch upper plate 152b and ball clutch lower plate 154, which are invented to rotate only at an angle of 90 degrees, and one-turn induction gear tanks 155 and 156 to rotate to one side, and a few intermediate gears, and It consists of pellets 159, etc., which inhibit the rotational force of the drive shaft (main shaft; 152) and delay the time, thereby rapidly closing the ball valve 140 after a set time.

However, such a mechanical timer has a necessity to solve such a problem due to the complexity of the structure as well as the inaccurate time control of the timer and the noise problem.

In addition, in the source technology described in Korean Patent Application No. 10-2000-0010220, it is not only used for special ball valves which have pre-wound springs wound on the ball valves themselves, but also has the trouble of setting the time by a separate button after turning the ball valves.

Therefore, the present invention intends to compensate for some disadvantages while using the apparatus of a mechanical timer of its own pre-registered patent, and digitalizes the portion of the pellet 159 which is the main cause of noise and time error, while simultaneously opening the ball valve and time. It is intended to develop and provide an electronic timer dedicated to ball valves that can be set and used on any ball valve.

The present invention operates a timer setting time while opening the ball valve while turning the timer handle by using a part of the components of the conventional pre-patented patented mechanical timer, and does not require a separate electric motor after the setting time The ball valve is invented to close the ball valve by using a spring 53 wound around the main shaft 52 to provide the user with operational convenience, low production cost, and precisely control the ball valve with a small current. It relates to an electronic timer device for blocking.

When the timer timer handle 30 of the present invention is turned at an angle of 90 degrees clockwise, a drive shaft (main shaft) 52 fixed to the main shaft 51 acting in conjunction with this is compressed at the same time as the spring spring 53 is compressed. Correctly opening the ball valve while turning the transmission shaft 54 connected to the handle 41 of the valve 40 counterclockwise, and turning the timer handle 30 by 90 degrees or more, the driven shaft 54 and the drive shaft The main shaft 52 is disconnected and at the same time the main shaft 52 is connected to the one-turn pinion 56 which is disconnected by the pitch removing part 52d of the main shaft 52. The pulse conversion switch 82 located at calculates the number of teeth of the main shaft 52 to set the operation time of the timer.

After the set time has elapsed, the reset switch 83 operates by an electrical signal to release the ratchet 59 holding the reduction gear 57, thereby compressing and winding the winding spring 53 on the main shaft 52. Rotate the drive shaft (main shaft) 52 counterclockwise to loosen it, and then interlock the driven shaft 54 and the handle 41 of the ball valve clockwise to close the ball valve. do.

For reference, the structure of the present invention and the role of each part can be easily compared with the patents previously filed. The numbers of the associated components have been matched, for example the actuating lever 130 will be described by naming the timer handle 30.

One configuration and operation of the present invention will be described with reference to the accompanying drawings, Figure 5 <C> is a view showing the shape of the transmission shaft (intermission shaft 54) and the main shaft (52), the characteristics of each structure and The interaction between the mechanisms is as follows.

When the timer handle 30 is rotated 90 degrees clockwise to set the time, the main shaft 52 fixed to the main shaft 51 moving in conjunction with the timer handle rotates and compresses the spring spring 53. At the same time, as shown in FIG. 7, two intermittent beams 52a and 52b formed on the main shaft 52 are engaged with the two intermittent grooves 54a and 54b of the driven shaft 54 sequentially. Intermission shaft 54 is rotated exactly 90 degrees counterclockwise.

At this time, the handle 41 of the ball valve fitted into the lower groove 54d of the intermittent mechanism as shown in Fig. 6B rotates 90 degrees counterclockwise to open the ball valve like an intermission shaft 54. .

The characteristic of the intermittent mechanism having two intermittent beams 54a and 54b and two intermittent grooves 54a and 54b is that the size of the intermittent mechanism is reduced and the rotational moment required to lock the ball valve is greatly reduced. Even without a spring or restoring device, there is a feature that the ball valve 53 can be sufficiently locked with only the springs 53 which are normally used.

Referring to the operating state of the apparatus having such characteristics through the internal perspective view of FIG. 8, FIG. 8A shows the initial state inside the timer before the main shaft 52 is rotated. While the main shaft 52 rotates clockwise by 90 degrees, the power sensing switch 81 activates the electronic timer while the pulse conversion switch 82 detects the number of gear teeth of the driving shaft 52. An internal perspective view showing the state of starting to calculate the valve shutoff time. At this time, the time display window 14 of the timer displays 0000. At this time, if the timer handle is released, one-turn rotation by the pitch removing part 52d of the main shaft 52 is performed. Since it is not in contact with the pinion 56, the spring is immediately released and closes the ball valve.

8C is an internal perspective view in which the main shaft 52 is rotated clockwise by 90 degrees or more, and the pitch removing portion 52d of the main shaft 52 passes through the one-turn pinion 56. FIG. While the two gears are engaged with each other and the electronic timer chip 80 is operated, a timer calculated by the set number of gear teeth counts down.

8D shows a state in which the reset switch 83 is operated to remove the ratchet 59 holding the reduction gear 57 after the set time has elapsed. The moment the ratchet 39 is moved is the main shaft. The winding spring 53 wound around the shaft 52 is suddenly released and the main shaft 52 is reversed to close the ball valve connected to the interface shaft 54 and the power is switched to the power saving mode. The return force of the sudden spring spring generated at this time is decelerated substantially by frictional resistance generated by the centrifugal force of the governor 58 installed at the top of the reduction gear 57, thereby smoothly closing the ball valve 40.

In addition, when the ball valve is to be closed before the set time during the use of the timer or during power saving, the reset (13) button on the timer upper case (10) of FIG. 3 is pushed, regardless of the reset switch (83) of FIG. 59) is separated from the reduction gear 57 to close the ball valve to be very convenient for the user.

As described above, the electronic timer device for blocking the ball valve manufactured according to the present invention allows the ball valve 40 to be closed by using only the spring spring 53 of the existing mechanical timer to control the ball valve 40 using a small amount of power. It can be manufactured at low cost because there is no separate electric motor and accurate time control, which is an advantage of electronic timer, can be widely used in ball valve devices requiring time control at home and industrial sites.
