Description

Connector for preventing illegal use of city gas}

The present invention relates to a city gas unauthorized use connector, and more particularly, to a city gas unauthorized use connector installed between the meter and the city gas valve to selectively open and close only by a separate key.

In general, a meter is installed on the supply pipe for supplying the city gas to the user, and the city gas staff reads the city gas usage of each household and charges for the usage by the meter.

However, there are users who do not pay bills for months after receiving the bill, in which case the city gas supply will be stopped.

In the conventional method of stopping the supply of city gas, the city gas supply is interrupted by turning the lever installed on the city gas supply pipe to lock the valve.

However, in the related art, the valve is selectively opened and closed by simply turning the lever. Therefore, some users who do not pay the city gas fee are unconscientious to continuously use the city gas by arbitrarily opening the valve after the city gas employee returns. .

However, there is no way to legally punish these people, and thus, the gas company cannot afford all the losses, and thus, there is a need for a method of effectively blocking city gas.

In addition, the city gas company will supply city gas only after the completion of various administrative measures and safety checks before supplying the city gas. By keeping the handle of the valve separate, the user has prevented unauthorized use, prevented various safety accidents caused by unauthorized use, and prevented theft of gas.However, users have frequently breached and used it. There has been a safety accident between years, but the gas company, the supplier, had no way to fundamentally block it.

Accordingly, the Utility Model Registration No. 247559 discloses a city gas unauthorized use connector applied for and registered by the present applicant.

Looking at the contents, the city gas unauthorized use connector is installed between the meter and the city gas valve is configured to open and close the city gas passage only through a separate key. That is, when the separate key is inserted into the key groove formed in the valve to rotate the opening and closing member installed in the valve, the city gas passage is opened and closed in the direction in which the rotating member is rotated.

Therefore, the city gas bill delinquents and unauthorized users before the gas supply completely blocks the unauthorized use of the city gas.

By the way, when opening and closing the city gas passage by rotating the opening and closing member by inserting a separate key into the key groove, the key company is configured to rotate 360 °, the gas company staff can not visually check whether the perfect opening and closing has been a disadvantage there was.

In other words, if the knob of the key is located in parallel along the longitudinal direction of the connector, the city gas passage is completely open, and if it is rotated by 90 ° orthogonally, the passage is completely sealed. Since there was no means for guiding to be 90 °, the staff had to adjust the rotational position of the key only with the naked eye, and thus could not confirm whether the city gas passage was completely opened and closed.

In particular, if the city gas passage is not completely sealed, the city gas is not blocked to be made surely, as well as the leakage of gas, there is a problem that caused the accident.

The present invention is devised to solve the various problems as described above, the purpose is to control the rotation range of the key precisely when opening and closing the city gas passage through the key to achieve a perfect opening and closing To provide a safe city gas unauthorized use connector.

In order to achieve the above object, the city gas unauthorized use connector according to the present invention is installed between the city gas valve and the meter, and inserts a separate key into the key groove of the opening and closing member through the formed key insertion hole of the tubular body to rotate the opening and closing member. In the city gas unauthorized use connector that selectively opens and closes the city gas passage according to the rotation direction, an arc-shaped rotation control groove is formed in the tubular body so as to be close to the key insertion hole, and a part of the key is inserted into the rotation control groove to guide it. The stopper protrusion is formed, and when the stopper protrusion is caught at one end of the rotation control groove when the key is rotated, the city gas passage is opened, and when the other end is caught, the passage is closed.
