Manual operation device for built-in gas cutoff apparatus

The present invention relates to a manual operation device of a buried gas circuit breaker, and more particularly, to reduce the manufacturing cost, prevent malfunction and increase durability by a simple configuration, manual operation device of a buried gas circuit breaker operation operation is smooth It is about.

In general, a gas circuit breaker is installed in a gas pipe while being connected to a gas detector that detects a gas leak. When the gas leaks, the electrical signal detected by the gas detector is transmitted to the gas blocker, and the gas blocker blocks the gas by the signal transmitted from the gas detector.

This gas circuit breaker is operated by a solenoid valve. The solenoid valve is opened and closed by the application of electricity, the gas should be cut off in case of fire. Therefore, the gas circuit breaker according to the related art allows the solenoid valve to be opened to move gas when electricity is applied, and the solenoid valve is closed to shut off the gas when electricity is cut off.

However, the gas circuit breaker according to the prior art is a gas is blocked when the power outage, there is a problem that the gas is blocked even in the case of a general power failure, not a fire. That is, there is a problem that cooking and heating are not possible when gas is cut off during normal power failure, not during a fire.

In addition, there is a problem that the above-described gas circuit breaker is exposed to the outside. That is, there is a problem that the gas circuit breaker protrudes from the wall in the same place as the apartment and is exposed to the outside, so it is not good in appearance.

In order to solve such a problem, there is a previously registered "filled gas circuit breaker (No. 10-0705547)" and "wall embedded gas shutoff valve structure (No. 10-0688082)".

The "embedded gas circuit breaker" according to the prior art is a box (BOX) shape of the case consisting of a front case and a rear case; A solenoid valve seated inside the rear case and regulating a gas flowing in the gas pipe by an electrical signal; It is connected to the end of the solenoid valve operation bar, it is composed of a connecting bar slid in the space inside the rear case and an operation switch for moving the connection bar by the operation, the operation switch is mounted on the end It is composed of a rotating bar that can be rotated by the rotary knob and the end of the rotating bar and an elliptical cross section is formed in an oval shape and a spring for rotating the rotating bar to its original position by an elastic force to move the connection bar by rotation. .

In addition, the "wall-filled gas shutoff valve structure" also includes a cover embedded in the wall of the building, a connection pipe bent in a 'b' shape connected to an external pipe inside the other side and connected to the internal pipe by a second screw part. The solenoid valve having a valve body for blocking the gas passage in an emergency in the horizontal portion of the connecting pipe is installed in a vertical direction, wherein the solenoid valve is formed so that the operating shaft connected to the valve body is exposed to the upper part of the solenoid valve. And, the long hole into which the operating shaft is fitted is coupled to the reset lever horizontally formed on one end of the operation axis, and the inclined surface is formed by the inclined surface of the reset lever forward and backward by forming an inclined surface on one side or the bottom surface of the reset lever Configured to reset.

That is, a device for blocking gas by embedding in a wall according to the prior art increases the manufacturing cost due to a complicated structure, and there is a problem in that failure occurs frequently and durability is reduced as various apparatuses are used.

Therefore, the present invention is devised to solve the problems as described above, the object of the present invention is to reduce the manufacturing cost by a simple configuration, prevent malfunction, increase the durability, the operation switch is a buried gas smooth operation It is to provide a manual operation of the circuit breaker.

The above object is achieved by the present invention, according to one aspect of the present invention, the manual operation device of the buried gas circuit breaker is formed in the inlet gas pipe groove through which the inlet gas pipe penetrates in the form of a box (BOX) is opened in the front side A rear case embedded in the wall; A front case mounted on the front open portion of the rear case and exposed to the outside, the front case having a draw gas pipe groove through which the draw gas pipe passes and a switch groove exposed to the operation switch; A solenoid valve mounted to the inlet gas pipe so that an operating shaft is positioned in the switch groove to regulate a gas flow in the inlet gas pipe; And an operation switch coupled to an end of the operating shaft of the solenoid valve and seated in the switch groove. A rectangular base is integrally formed on the outer circumferential surface of the inlet gas pipe, and a support is mounted on the base in parallel with the operating shaft. And a switch seat having a seating groove formed at the center thereof is mounted at an end of the support, and the operation switch is seated at the switch seat.
