Abstract

The present invention relates to a technique for reinforcing the elastic force of a spring for closing a gas valve to operate a drive cylinder in cooperation with the unrolling movement of the spring. Air is stored separately in the process of supplying the air from an external air supply tank to the drive cylinder for operation of the drive cylinder to open the gas valve.

According to the present invention, each side of a grip member is straight for an insertion step of the grip member surrounding a handle of the gas valve to meet an outer diameter of the handle of the gas valve, thereby minimizing idle rotation during rotation of the grip member for rotating the handle of the gas valve.

Description

Dual type auto valve shutter with air pressure and elasticity

The present invention reinforces the spring force of the spring spring to close the gas valve, thereby enabling the drive cylinder to cooperate with the spring release operation.

More particularly, the present invention relates to a method of operating a drive cylinder for opening a gas valve, in which air is separately stored in the process of supplying air from an external air supply tank to a drive cylinder, The present invention relates to a technique for operating a driving cylinder by cooperating with the unwinding of a spring using an air that has been separately stored.

Generally, when the gas in the gas cylinder is supplied to the outside, the gas valve located at the upper portion of the gas cylinder is opened, and when the supply to the outside is blocked, the gas valve is closed.

In order to open / close the gas valve, a gas valve knob protruding upward from the gas valve is rotated clockwise / counterclockwise so that the gas valve is opened / closed in conjunction with the rotation of the gas valve knob .

Conventionally, when a gas valve is closed and the gas valve is closed when the gas valve is opened, a technique for closing the gas valve by the released elastic force of the spring is released.

The open state of the gas valve according to the clockwise rotation of the spring member 220

First, in order to maintain the open state of the gas valve according to the clockwise rotation of the hand-loaded rod member 220, the first suction member 251 of the multi-way valve 250 connected to the air supply tank 610 through a pipe Air supplied from the air supply tank 610 is injected into the multiway valve 250.

Air injected into the multiway valve 250 is supplied to the driving cylinder 240 sequentially through the first exhaust member 252 and the first inlet member 241, which are connected to each other by piping.

As a result, the drive cylinder 240 operates in response to the clockwise rotation of the spring loaded rod member 220 for the open operation of the gas valve.

Here, air supply from the air supply tank 610 to the drive cylinder 240 must be continuously performed while the gas valve is being opened.

Through the second exhaust member 253 and the three-way connector 260 connected to each other in the process of supplying air from the air supply tank 610 to the driving cylinder 240 while the gas valve is opened, Air moves and is reserved in the sub air capsule 230.

When the gas valve is closed, for example, when the air supply tank 610 is replaced or air movement from the air supply tank 610 to the multiway valve 250 is blocked, The gas valve should be closed quickly by turning clockwise.

As a result of the sensing of the air pressure sensor (not shown) that senses the air pressure through the first suction member 251, it is detected that air is not supplied from the air supply tank 610 to the first suction member 251 The control unit (not shown) switches and closes the first suction member 251, the first exhaust member 252 and the second exhaust member 253 and the second suction member 254, the third exhaust member 255 ).

As a result, the air stored in the sub air capsule 230 is drawn into the multiway valve 250 via the third pipeline 263 and the second suction member 254, And is supplied to the driving cylinder 240 via the third exhaust member 255 and the second inlet member 242 connected thereto.

Subsequently, in accordance with the supply of air through the second inlet member 242, the driving cylinder 240 operates to rotate the manual winding rod member 220 counterclockwise, thereby closing the gas valve.

Of course, the operation of the driving cylinder 240 for rotating the manual winding rod member 220 in the counterclockwise direction to close the gas valve may be manually performed by an operator located in the field.
