Description

Automatic opening and closing device for valves {Automatic valve switch}

The present invention relates to an opening and closing device for automatically opening and closing an intermediate valve installed in a pipe to which gas or liquid is transported to block or open the inflow thereof, and more specifically, presses the knob of the intermediate valve by forward and reverse driving of a motor. The present invention relates to an automatic opening and closing device for a valve to rotate and at the same time to safely block and open the inflow of gas or liquid material.

In general, the gas or liquid substance flowing through the pipe is controlled in order to control the flow rate or to close the pipe in consideration of safety problems, such as a valve between the stove and the pipe, the boiler and the hose. These intermediate valves are mainly used for home or industrial use and are provided in various kinds according to their purpose.

The intermediate valve is largely divided into a ball valve and a valve cock, which is called a lever valve, which is manually operated. The ball valve includes a ball having a hollow formed inside the body in an open state of an upper / lower portion, and the ball The rotating shaft is formed to protrude from the body in the center of one side of the hollow ball is rotated by rotating the lever fixed to the rotating shaft to adjust the amount of gas or liquid material flowing into the device from the pipe or to open and close the pipe for safety.

On the other hand, the valve cock is open upper and lower, the ball is formed in the hollow formed inside the body formed with a locking jaw on one side, the rotating shaft is formed to protrude from the body in the center of one side of the ball at one end of the rotating shaft The locking groove into which the locking jaw is inserted is fixed to the knob formed on one side by screwing, and a spring having a predetermined elasticity is inserted between the knob and the body.

Such a valve cock is coupled to both ends of the pipe as is known to serve to inlet or block the gas supplied from the pipe, etc. In order to introduce the gas, first push the knob toward the body side to catch the jaw Rotating to one side in the state to be inserted into the engaging groove and the rotating shaft coupled to the knob and the ball embedded in the body rotates at the same time so that the hollow formed in the center of the ball coincides with the inside of the pipe smoothly inflow of gas After the use of the gas is completed, the knob is rotated to the other side by holding the knob and rotating the shaft and the ball at the same time, the knob is pushed forward by the elasticity of the spring and the locking groove formed on one side of the locking jaw formed on one side of the body. To prevent the knob from rotating and the pipe to be securely closed. will be.

By manually operating such intermediate valves to control the inflow of gas or liquid materials or closing the pipes for safety reasons, the user may always have to check and check the opening and closing of the intermediate valves. There was a risk of safety accidents.

In order to solve the above problems, the valve cock connection opening and closing device of the gas circuit breaker described in Utility Model Registration No. 295876 has been recently used, and its configuration is provided at the rear as shown in FIGS. 1A and 1B to provide a valve cock. Connection of the rotary body 300 receiving the knob 210 or the valve rotating shaft 220 to open and close the 200 and the outside of the gas detection sensor (S) and the gas detection sensor (S) for detecting the leakage of gas In the gas circuit breaker including a driving motor (M) for rotating the connection rotating body 300 by receiving a signal, a groove 302 is formed in the rear of the connecting rotating body 300, the spring 310 inside the It is possible to move forward and backward through the) and is configured to be equipped with a movement receiving plate 320 to receive the knob 210 or the valve rotation shaft 220 is inserted.

The valve cock connection opening and closing device having such a configuration is the rear of the main body 230 in a state in which the knob 210 of the valve cock 200 is inserted between the insertion protrusion jaws 322 formed at the front of the movable receiving plate 320. When the fixing portion 232 is formed in the valve cock 200 is firmly fastened to the state that the moving receiving plate 320 is always pressing the knob by the elasticity of the spring 310, that is, the locking of the knob 210 Since the locking jaw 202 formed in the valve cock 200 body is inserted into the groove 212, the connecting rotor 300 interlocked with the driving motor M mounted inside the main body 230 is 90 °. As the knob 210 is easily rotated, the opening and closing of the valve cock 200 can be automatically controlled.

However, since the valve cock connection opening and closing device is in a state where the movable receiving plate 300 always pushes the knob 210, the locking jaw 202 is secured to the locking groove 212 that is a safety device of the valve cock 200 itself. In this inserted state, that is, the knob 210 is always rotatable, so the valve cock 200 may not function as a safety device of the valve cock 200 itself, and thus the valve cock 200 may be opened due to inadvertent or breaker malfunction. It has occurred frequently and raised the reliability and safety issues of the product.

When the spring 330 supporting the movable receiving plate 320 with a predetermined elasticity decreases in elasticity due to prolonged use, the movable receiving plate 320 gradually moves to the groove 302 of the connecting rotating body 300. Since the adhesive force is deeply inserted and the adhesion to the knob 210 is lowered, this causes the knob 210 to be pushed forward by the elasticity of the spring 240 supporting the knob 210 of the valve cock 200. When the groove 212 is caught by the locking jaw 202, the knob 210 cannot be rotated. In this situation, when the connection rotor 300 is rotated to open the valve cock 200, the driving motor ( Excessive load is generated in M) and its life is shortened or broken, resulting in the disposal of expensive circuit breakers themselves.

In addition, the conventional valve opening and closing device or gas circuit breaker has been used in a limited range of use because it simply performs a function of automatically closing the pipe by automatically rotating the knob of the valve cock when gas leaks.

Therefore, in order to solve the above problems, the present invention provides a shaft and a rotating cam rotated by a drive motor so that the operation of the safety device installed in a conventional manual valve can be applied as it is, while simultaneously releasing the safety device and the knob continuously. The purpose of the present invention is to provide an automatic opening and closing device for a valve so that the inflow or blocking of gas and liquid materials can be made safely and easily by rotating the same.

In addition, the present invention has another object devised to provide convenience in use by installing a control unit for supplying or cutting off power by the timer operation according to the voice or button input to the drive motor.

In order to achieve the above object, the present invention is applied to a valve installed in a pipe into which gas or a liquid material is introduced, and automatically opens by rotating the valve forward / backward inside the main body installed as a fixing means in the pipe.
