It is related to the safe lock for fluid supply piping of industrial facilities that is easy to improve productivity.

In general, a valve is installed to selectively block the flow of fluid in a fluid supply pipe for supplying gas generated from a steelmaking facility to industrial facilities such as a steelmaking facility or a power generation facility.

These valves have a problem of suffocation when entering to repair and repair steel or power generation facilities because gas leaks finely due to assembly tolerances between the housing and the valve side.

In order to solve this problem, a safe lock is installed to selectively block the supply of gas to the fluid supply pipe.

Conventionally, the safe lock is difficult to use because the fluid supply pipe and the fluid supply pipe are manually opened and the operator installs and removes the safe lock, making it difficult to use, thereby causing a gas accident.

In order to solve the above problems, the name of the invention "Safelock for gas supply piping of industrial equipment" of Korean Patent Registration No. 10-1542086 is known. As a result, the first stream having one surface fixed on the coaxial of the first piping A housing, a second stream housing having one surface fixed on the coaxial of the second pipe, a driving means having a rotating shaft fixed to and rotated on the other surface of the second stream housing, and a second stream while being rotated by the driving means A main gear part having a main gear installed to rotate parallel to the axis center of the housing, an idle gear part having an idle gear rotatably installed on the other surface of the second stream housing so as to engage and rotate with the main gear, and the idle gear The jack is equipped with a gear part that meshes with the part, and a pivoting part is installed so that one end is rotatable in the second stream housing and screwed to the first stream housing to open or close the gap between the first and second stream housings. Jack bolt means having a bolt, and is installed between the first stream housing and the second stream housing, the rotational force by the driving means is transmitted to the gear portion of the main gear, idle gear and jack bolt means, the jack bolt rotates When the distance between the first and second stream housings is widened, the spreader plate is pushed or pulled in either direction to be guided by the jack bolts of the jack bolt means so as to be positioned in the flow path between the first and second pipes. After selectively passing through the spreader flange or the blocked spreader flange in a blocked state provided with a through hole provided in the spreader plate, the contact between the first and second stream housings by the operation of the driving means is selectively performed. It includes safe lock spreader installed to supply and shut off the fluid.

Therefore, the safer spreader installed between the first stream housing connected to the first pipe and the second stream housing connected to the second pipe is transmitted to the gear portion of the main gear, the idle gear and the jack bolt means by the driving means and jacks. When the bolt rotates, the gap between the first stream housing and the second stream housing is widened, so it is easy to use when the gas pipe is locked, so it is easy to use in the field, and there is no leakage of gas. Productivity is improved.

In addition, by preventing the rotation of the idle gear by an anti-rotation means installed on the second stream housing, it is possible to prevent gas from leaking.

In addition, a safe spreader is installed using a spreader plate having a thin material, so that a cut-off spreader flange and a pass-through spreader flange are installed, so that the manufacturing cost is low and it is easy to handle and operate the handle.

However, the Republic of Korea Patent No. 10-1542086 also has a safex spreader installed between the first stream housing connected to the first pipe and the second stream housing connected to the second pipe, and the rotational force of the main gear, idle gear and jack bolt by the driving means. When the jack bolt is rotated by being transmitted to the gear portion of the means, the gap between the first stream housing and the second stream housing is increased, or the driving means in a state where the positions of the first pipe and the second pipe are fixed inside the factory. The rotational force of the main gear, the idle gear, and the jack bolt means is transmitted to the gear part, so that the rotation of the jack bolt to open the gap between the first pipe and the second pipe is very difficult, and the driving means, idle gear, and jack bolt are driven by excessive rotation. There was a problem that the gear portion of the means was damaged.

In addition, there is a problem in that automation is difficult due to a structure in which the widths of the first pipe and the second pipe are varied.
