Figure 2 is a cross-sectional view of the connector used in the present invention,

Figure 3 is an exploded perspective view of a conventional intermediate valve.

The present invention relates to a connecting device for connecting a mechanical timer for opening and closing the intermediate valve of the gas supply pipe to the intermediate valve, and in particular, by connecting the timer to the intermediate valve spindle from which the handle of the intermediate valve of the existing gas pipe is removed through the connector. When this elapses, the present invention relates to a timer valve opening and closing device for the intermediate valve of the gas supply pipe to automatically open and close the gas pipe by the operation of the mechanical timer.

The gas pipe has an opening / closing valve, so-called gas cock, which shuts off the gas flow in the gas pipe when not in use. This on-off valve is to rotate by pressing the knob when rotating the knob for stability. Recently, a valve has been developed in which a timer device for opening and closing the valve when the above-mentioned valve is attached to the valve is installed or attached to the valve, or when the valve itself is opened for a certain time.

As a timer device attached to the gas valve opening and closing device for opening and closing the gas supply after a certain time has elapsed, there are an electronic and a mechanical timer device.

Utility Model Registration No. 0248753 discloses a gas safety device in which a gas valve is automatically locked at a set time by setting a time by a volume switch and fixing a time set by a reset switch. Korean Patent Laid-Open Publication No. 10-2004-0106899 sets a usage time and when the set time has elapsed, power is supplied to the motor to rotate a gear connected to the motor shaft to rotate a gear formed on the knob of the valve to rotate the knob. The gas timer automatic lock of the gas range has been disclosed to block the flow. All of these electronic timer devices had to be connected to a power source, so they could not be used for gas valves in locations where power could not be connected. In particular, the above-described gas timer opening and closing device may use a electronic device, which may cause a high production cost.

Utility Model Registration No. 0280414 is provided with a timer configured to set the opening time of the gas flow path by installing a handle on the upper side of the timer by directly connecting the timer shaft to a rotating shaft for rotating the knob of the intermediate valve used for gas piping. Gas intermediate valves have been disclosed. This gas intermediate valve is to be installed in the upper portion of the support of the timer, the intermediate valve is installed, it is fixed to the cylindrical gas pipe, there is a problem that the timer device is installed unstable.

Utility Model Registration No. 0165975 discloses a valve device in which a timer is provided by connecting a ball valve that blocks a flow path to a rotating shaft of a timer. These valves are connected to the ball valve for blocking the gas flow path to the axis of the timer has a problem of increasing the production cost of the valve appears and there is a problem that can not be used in the existing valve.

Korean Patent Laid-Open Publication No. 2001-0110516 attaches a rubber packing to an operation member which is erected vertically inside a gas pipe line and installs a ball bearing at the end of the operation member to be connected to a timer through the ball bearing. A gas intermediate valve has been disclosed which is equipped with a timer configured to open and close the gas flow in the piping as the operation moves up and down. This gas valve not only can not be installed in a stable installation of the valve, but also the configuration of the valve is different from the conventional gas valve, it can not be applied to the gas valve already in use.

Korean Utility Model Publication No. 20-0176719 discloses a gas pipe valve provided with a timer that is configured such that a timer is integrally installed between operations of a gas valve and a gas pipe is automatically closed when a predetermined time elapses. This valve also has a problem in that the timer is directly connected between valve operations and thus cannot be used in existing gas valves.

Utility Model Publication No. 2003-0031383 is installed in the valve cock of an existing gas valve that presses and rotates to cut off the gas pipe. When the knob is turned to the open position, the gas valve cock is rotated while the gas pipe is opened and a predetermined time is Over time, the mechanical timer device has been disclosed, which is configured to close the gas line by rotating the gas valve cock to the shut off position when the handle returns to its original position. The timer device is formed so that the clamp insertion groove protrudes to the bottom of the lower case cover, the insertion jaw of the clamp fixed to the gas pipe is inserted to be fixed to the gas pipe. The problem with the above-described mechanical timer is that the timer is not stably fixed to the gas pipe when installed on the cylindrical outer periphery of the gas pipe, and stably fixed according to the size of the nut when installed on the nut of the gas valve cock. In particular, the gas valve cock may not operate stably because the height of the valve cock is not constant and there are differences in the height of the valve cock or when the size of the octagonal nut of the valve cock is different.

In order to improve the problem of coupling the above-described mechanical timer to the intermediate valve of the gas supply pipe, the mechanical connector is configured to replace the connector in the field according to the height of the valve handle by interposing a connecting connector on the bottom of the timer according to the valve handle height. A timer has been developed. However, this type of mechanical gas timer is designed on the premise that the knob of the intermediate valve must be inserted into the coupling groove of the timer because the problem of the combination of the timer and the intermediate valve in the conventional mechanical timer is eliminated. If it is not inserted, the problem may occur.

Therefore, in this type of mechanical timer, there is a problem in that a timer of a single specification cannot be used for all gas valve cocks, and a timer device must be selected and used according to the size and height of the gas valve cock.

Therefore, in the timer device used for the gas valve cock of the above-described type, unlike the conventional timer connection device configured to rotate the gas valve cock, the timer device is made by connecting the main shaft without the handle of the intermediate valve to the mechanical timer device. There is a need for a device that can be connected so that the intermediate valve of the gas supply pipe can be opened and closed stably.

The intermediate valve of the gas supply pipe is opened and closed by the rotation of the main shaft of the intermediate valve. Conventionally, the method of connecting the timer with the handle attached to the intermediate valve has been studied. However, since the intermediate valve is opened and closed by the rotation of the main shaft, the gas supply pipe is opened and closed by rotating the main valve of the intermediate valve without the knob, that is, the knob. The idea was to complete the present invention. An example in which a timer is directly coupled to a main shaft from which a knob of a known intermediate valve is removed is not known yet. In general, there may be a method of connecting a timer to a known intermediate valve spindle, but when connecting the main shaft of the known intermediate valve to the timer, if the timer is not in close contact with the spindle, even if the timer rotates, Not only can it appear unrotated, but noise can also be generated when the spindle is rotated. It is therefore important to ensure that the timer is in close contact with the main shaft of the intermediate valve.

In particular, when the timer is directly connected to the main shaft, when the depth of the coupling groove formed to insert the main shaft into the timer does not coincide with the height of the main shaft, the coupling with the intermediate valve becomes incomplete even though the timer rotates.

In the present invention, in order to improve the above problems, the main shaft of the timer and the intermediate valve are connected to each other so that the main shaft of the timer and the intermediate valve can be safely coupled. The connector has a four-sided hole in which the main shaft of the intermediate valve is inserted at one end, and the other end has a connection part which is inserted into the coupling groove formed in the timer and is coupled. A spring is inserted between the timer and the connector so that the timer is It was to be tightly coupled with. In addition, the connector has a spring inserted into the connector at the center part, so that the spring always pushes the connector toward the main shaft so that the connector always comes into close contact with the intermediate valve of the gas supply pipe.

The object of the present invention is to connect the intermediate valve spindle and timer to which the knob of the valve cock of the existing gas valve intermediate valve is removed so that the timer can be operated safely, and the gas is configured to not generate noise when the spindle rotates by the timer. It is to provide a mechanical timer connection for opening and closing the intermediate valve of the supply pipe.

The object of the above-mentioned design is to form a four-sided coupling groove in the gas timer and remove the knob of the gas supply pipe intermediate valve. Timer for opening and closing the intermediate valve of the gas supply pipe of the present invention is coupled to the intermediate valve through a connector having a connection key keyed to the coupling groove of the mechanical timer described above through a spring between the intermediate valve spindle and the coupling port By the device.

The present invention forms a quadrilateral coupling groove on one side of the timer, and has a four-sided axial hole coupled to the main shaft of the intermediate valve at one end, and a four-sided hole formed at the timer for the intermediate valve at the other end. Prepare the connector with the connection part inserted into the joint, insert the main shaft of the intermediate valve with the handle removed into the axial hole of the connector, and insert the connection section of the quadrilateral section of the connector into the coupling groove formed in the timer. Intermediate valve opening and closing timer connection device of the gas supply pipe is configured to couple through a spring interposed therebetween.

In the present invention, the axial hole of the quadrilateral cross section formed in the connector should be formed slightly deeper than the length of the gas supply pipe intermediate valve main shaft so that the outer end of the main shaft does not close to the bottom of the hole when the connector is coupled to the timer. The most preferred axial hole of the connector is to form the connector in the longitudinal direction.

In the present invention, the timer installed inside the case uses a conventional mechanical timer device, but the hole into which the intermediate valve of the gas supply pipe is inserted is formed so that the coupling portion of the connector is key-coupled. Such a timer device is, for example, a timer device disclosed in Utility Model Publication No. 2003-0031383. The timer device is a knob of the intermediate valve is inserted into the groove formed in the timer, and when the knob rotates according to the rotation of the timer, the knob of the gas valve is rotated to open and close the intermediate valve, but the timer used in the present invention is The knob of the valve, that is, the part where the knob is inserted, has a quadruple hole that can be keyed with the connector of the connector.
