Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to an electric gas safety valve, and more particularly, to a gas safety valve for controlling the gas supply of a gas supply pipe conveniently and safely by driving the knob of the gas valve automatically by a wired or wireless control signal The present invention relates to an electric gas safety valve capable of preventing a danger of a gas leakage while preventing a gas leakage.

Generally, homes and businesses use gas appliances such as gas ranges, gas ovens, and gas boilers that are made of gas such as liquefied petroleum gas (LPG) or liquefied natural gas (LNG) for food cooking or heating.

Such a gas appliance is connected to a gas tank such as an outdoor gas storage tank or a city gas construction through a gas pipe to receive the gas, and an intermediate valve is provided between the gas appliance and the outdoor gas storage tank or the gas tank for controlling inflow of gas.

The user opens the intermediate valve to supply gas to the gas appliance, turns on the ignition device installed in the gas appliance, and ignites the gas to use the gas appliance do.

In addition, when the use of the gas appliance is completed, the user turns off the ignition device of the gas appliance and extinguishes it, and then closes the intermediate valve to shut off the gas supply.

In this way, every time a user uses a gas appliance, the intermediate valve is opened and used and then closed to achieve the original safety function. However, since the intermediate valve is generally installed at a position spaced apart from the gas appliance for safe use, State, and only the ignition device of the gas appliance is turned off in many cases.

That is, the present mechanical manual valve has a problem that the use rate of the intermediate valve is reduced due to inconvenience of the user, thereby improving the potential risk of gas accidents.

To solve the above-mentioned problem, an apparatus for automatically shutting off an intermediate valve has been developed. However, the conventional gas valve interrupter, which is currently being developed, is complicated in configuration and has a problem that it is difficult for a general user to install the gas valve interrupter after replacing the existing intermediate valve.

In addition, a conventional electric valve is installed in a state in which a valve is squeezed at the time of initial installation, and the gas pipe is opened and closed only by using rotation. In this way, when the valve is installed in a compressed state, there is a problem that opening and closing of the gas piping is not performed perfectly. Further, since the valve is kept in a compressed state, the risk of gas leakage remains.

Configuration of electric gas safety valve

FIG. 1 is a perspective view of the electric gas safety valve according to the present invention, FIG. 2 is an exploded perspective view of the electric gas safety valve according to the present invention, and FIG. 3 is a sectional view taken along line A-A of FIG. The electric gas safety valve 10 according to the present invention is an apparatus capable of opening and closing the knob 610 of the gas valve 600 by electric power even if the user does not directly control the electric gas safety valve 10 according to an electric signal connected by wire or wirelessly. As shown in FIGS. 1 to 3, the electric gas safety valve 10 includes a housing, a first bracket 110, a second bracket 120, and a power unit 300.

The housing (not shown) provides a space in which the first bracket 110, the second bracket 120, and the power unit 300 can be seated and supported. In order to achieve this object, And a through hole through which the knob 610 of the gas valve 600 can be connected may be formed in any shape. In the present invention, the housing is not shown in order to more clearly show the structure of the first bracket 110, the second bracket 120, and the power unit 300. Such a housing is commonly used in the art, and a detailed description thereof will be omitted.

The first bracket 110 is rotatably installed on one side of the housing, preferably one side of the other side of the gas valve 600 opposite to a side of the gas valve 600 on which the through-hole is formed so that the knob 610 can be connected. That is, the first bracket 110 does not linearly move on one side of the housing but is provided to be rotatable. The structure of the first bracket 110 will be described in more detail with reference to the drawings.

The first bracket 110 is formed in a cylindrical shape which is easy to rotate as a whole. At this time, in the center of one end face of the first bracket 110 which contacts the one face of the housing, a cylindrical projection 113 for coupling to the housing is formed to protrude so as to freely rotate on one side of the housing, (Not shown) or the like on the outer circumferential surface of the cylinder block.

The other longitudinal end portion of the first bracket 110 facing the one end surface of the first bracket 110 is formed to have a relatively small diameter as compared with one end portion of the first bracket 110 having the engagement protrusion 113, So that the step 111 is formed at the center of the direction. At this time, a latching protrusion 112 having a sloped surface formed in a U shape or a V shape is formed on one side of the step 111.

A first support bar insertion groove 114 into which the support rod 500 can be inserted is formed on the other side of the first bracket 110 opposite to the one end surface of the coupling bracket 113. The first support bar insertion groove 114 can be inserted into the center of the support bar 500 in the longitudinal direction so that the support bar 500 can be inserted and the rotation force of the first bracket 110 can be stably transmitted to the second bracket 120 Depth.

The second bracket 120 has a shape corresponding to that of the first bracket 110. A first end of the first bracket 110 having a reduced diameter may be inserted into a first surface of the first bracket 110 facing the first bracket 110 And a coupling groove 123 is formed on the other surface of the coupling groove 121 on which the coupling groove 121 is formed so that the knob 610 of the gas valve 600 can be inserted. That is, the second bracket 120 is coupled such that the end of the first bracket 110 having a reduced diameter is inserted into the coupling groove 121, and the other side is provided at a position corresponding to the through hole of the housing.

An engaging groove 122 is formed at one side of the rim of the second bracket 120, preferably at one side of the rim forming the engaging groove 121, corresponding to the engaging projection 112 of the first bracket 110 . Since the second bracket 120 is formed with the engagement groove 122 having the shape corresponding to the engagement protrusion 112 of the first bracket 110 when the first bracket 110 rotates, The second bracket 120 linearly moves along the inclined surfaces of the engagement protrusions 112 and the engagement grooves 122 of the second bracket 120 by the projection length of the engagement protrusion 112. [

A support rod 500 may be inserted into the bottom surface of the coupling groove 121 in the same manner as the first bracket 110 so as to restrict the linear movement of the second bracket 120 and to rotate with the first bracket 110 The second support bar insertion groove 124 is formed. However, the second support bar insertion groove 124 of the second bracket 120 is formed to be offset from the first support bar insertion groove 114 of the first bracket 110 by a predetermined angle. When the second support bar insertion groove 124 is formed at the same position as the first support bar insertion groove 114, the support rod 500 to be described later is inserted from the initial state into the first and second support bar insertion grooves 114, The second bracket 120 does not move linearly and rotates together with the first bracket 110 and can not press the knob 610 of the gas valve 600 because the second bracket 120 is inserted into the groove 124. Since the knob 610 of the gas valve 600 is configured to rotate after being compressed to a predetermined depth, the second bracket 120 is linearly moved by a predetermined length and the knob 610 of the gas valve 600 is compressed It is preferable that the second support bar insertion groove 124 of the second bracket 120 is formed to be offset from the first support bar insertion groove 114 of the first bracket 110 by a predetermined angle.

The angle at which the first support bar insertion groove 114 and the second support bar insertion groove 124 are offset from each other is preferably formed so that the second bracket 120 can linearly move to a length corresponding to the compression length of the knob 610 Do. That is, when the depth of the knob 610 of the gas valve 600 is short, the angles of deviation of the first and second support bar insertion grooves 114, 124 are narrow, When the depth of the knob 610 is deeper, the first support bar insertion groove 114 and the second support bar insertion groove 124 should have a wide angle of deviation. That is, it is preferable to form the offset angle of the first and second support bar insertion grooves 114 and 124 according to the compression length of the knob 610 of the gas valve 600.

The second support bar insertion groove 124 may have a hemispherical shape or a predetermined inclined surface in the rotation direction of the support bar 500 so that the support bar 500 can be easily inserted and removed. At this time, the depth of the second support bar insertion groove 124 is set to a depth at which one end of the support bar 500 can be slightly caught, so that the support bar 500 can be easily inserted and removed, while the rotation force of the first bracket 110 is transmitted to the second bracket 110. [ (120). The depth of the second support bar insertion groove 124 may be variously set in consideration of the rotation resistance of the knob 610 and the like.

The support bar 500 is inserted into the first and second support bar insertion grooves 114 and 124 to transmit the rotational force of the first bracket 110 to the second bracket 120, So that the second bracket 120 rotates together with the rotation of the second bracket 120. The support bar 500 may be formed to have any cross section, but preferably has a circular column shape. The support bar 500 may be formed to have a circular column shape and correspond to the second support bar insertion groove 124 at one end corresponding to the second support bar insertion groove 124 And it is preferably formed in a hemispherical shape so as to be easily inserted into and detached from the second support bar insertion groove 124.

An elastic member 510 for elastically supporting the support bar 500 in the direction of the coupling groove 121 of the second bracket 120 is provided between one end of the support bar 500 and the first support bar insertion groove 114. When the other end of the support rod 500 is moved to a position corresponding to the second support bar insertion groove 124 by the rotation of the first bracket 110, the elastic member 510 is inserted into the second support bar insertion groove 124 so that the rotational force of the first bracket 110 can be stably transmitted to the second bracket 120. In addition, the first bracket 110 is easily pressed according to the rotation of the first bracket 110 so that the support bar 500 can be easily detached from the second support bar insertion groove 124. Any elastic material may be used as long as the elastic member 510 can achieve the above-mentioned object, but it is preferable to use a coil spring.

The power unit 300 generates power to rotate the first bracket 110 and transmits the generated power to the first bracket 110 to rotate the first bracket 110. The power generating unit 300 may be any power generating apparatus capable of forward and reverse rotations, but it is preferable to use a motor capable of forward and reverse rotation.

The power unit 300 may transmit power to the first bracket 110 through various methods depending on the shape and size of the housing or the installation environment. For example, the power unit 300 and the first bracket 110 are disposed parallel to each other, the driving gear 410 made of a spur gear is connected to the rotation center shaft 310 of the motor, the first bracket 110, Preferably, the engaging projection 113 is connected to the driven gear 420, which is a spur gear, with the driving gear 410 so as to be engaged with each other. Since the driving gear 410 and the subsidiary gear are engaged with each other, the rotational force generated in the driving unit is transmitted to the first bracket 110.

The power unit 300 may be disposed at a predetermined angle to the first bracket 110 and the drive gear 410 and the driven gear 420 may be formed of corresponding bevel gears, The rotation center axis 310 of the first bracket 300 and the coupling protrusion 113 of the first bracket 110 may be directly connected.

As described above, the arrangement of the power unit 300 can be variously configured in consideration of the use environment and the shape and size of the housing.

The use of electric gas safety valve

The use of the electric gas safety valve 10 having the above-described configuration will be described in detail as follows.

In general, the knob 610 of the gas valve 600 is held elastically supported by a coil spring or the like. Thereafter, in order to open or close the gas valve 600, the knob 610 must be pressed to a predetermined depth to rotate the knob 610.

The electric gas safety valve 10 according to the present invention is coupled to the knob 610 of the gas valve 600 having the above-described configuration. The coupling of the electric gas safety valve 10 is inserted into the connection groove 123 of the second bracket 120 through the through hole of the housing.

When the first bracket 110 rotates, the second bracket 120 linearly moves in the direction of the knob 610 along the inclination of the latching protrusion 112 and the latching groove 122.

5, since the support bar 500 is separated from the second support bar insertion groove 124, even if the first bracket 110 rotates, the support bar 500 is inserted into the second support bar insertion groove 124, The second bracket 120 does not rotate and only linearly moves in the direction of the knob 610 along the inclined surfaces of the engaging projections 112 and the engaging grooves 122 until the second bracket 120 is inserted.

Fig. 7 is a side view of the electric gas safety valve showing a state in which the first bracket and the second bracket rotate together, and Fig. 8 is a schematic plan view showing a state in which the second bracket rotates together with the rotation of the first bracket. When the first bracket 110 rotates at a predetermined angle, that is, the first support bar insertion groove 114 and the second support bar insertion groove 124 are rotated at an angle larger than the mutual deviation angle, the support rod 500 Are inserted into the first support bar insertion groove 114 and the second support bar insertion groove 124 by the elasticity of the elastic member 510 as shown in Fig. When the support bar 500 is inserted into the first and second support bar insertion grooves 114 and 124, the second bracket 120 is rotated in a direction corresponding to the rotation of the first bracket 110, Rotate together.

The knob 610 inserted into the connecting groove 123 of the second bracket 120 is rotated together with the second bracket 120 rotating corresponding to the rotation of the first bracket 110 to open the gas valve 600 Or close it.

Thereafter, the driver may be reversed to close the opened valve or open the valve that has been closed.
