Piping Work Structure Using One-Touch Check Valve}

The present invention relates to a conventional valve piping structure in which two valves are used together, which can be replaced using a single valve, and is conventionally piped with a gate valve and a check valve, or with a ball valve and a check valve. It relates to a pipe assembly structure using a one-touch check valve to replace the one with a valve to perform the function.

The present invention relates to a pipe assembly structure using a one-touch check valve to facilitate the pipe connection by forming a screw line on the outside of the valve body instead of the conventional welded pipe construction, or screwed pipe construction in which the screw wire is formed inside the valve body. will be.

The present invention is a method of insulating a pipe assembly structure. Instead of insulating the main body of a conventional valve, a pipe using a one-touch check valve using an insulated straight nipple employing an insulation material in an nipple that is essentially used in a pipe assembly structure. An assembly structure.

The conventional piping structure is a pipe valve or gate valve and additionally using a check valve to prevent backflow, which is a disadvantage in that the construction is complicated, space can not be used efficiently, and cost is uneconomical.

Conventional piping structure requires not only the welding skills of highly skilled technicians by welding pipes and valves, pipes and nipples, but also when the pipes are damaged or damaged, even parts other than the damaged parts must be disposed of together. Of course, pipe construction and maintenance is difficult.

Conventional piping structure, in addition to the above-mentioned welding type, the screw thread is formed by forming a thread inside the body, such as a valve or nipple, but this requires a skilled technique, it takes a lot of time to construct a large economic burden It is a disadvantage. The conventional method of insulating the piping structure is to insulate the necessary part of the piping structure because the insulation is performed on the valve itself, and the disadvantage is that the economic burden is large.

Accordingly, an object of the present invention is to provide a pipe assembly structure using a one-touch check valve that can be installed more economically and conveniently by replacing two valves with one one-touch check valve.

Furthermore, an object of the present invention is to provide a pipe assembly structure using a one-touch check valve that is easier to pipe construction and maintenance by forming a screw line on the outside of the body, such as a valve.

Furthermore, an object of the present invention is to provide a pipe assembly structure using a one-touch check valve that can insulate the necessary parts of the pipe structure by insulating the straight nipple which is essentially used in the pipe structure.

As shown in FIG. 5B, when the fluid proceeds in the direction of the arrow and the supply of the fluid is stopped, the disks 405 and 505 are closed by the self-weight and the backflow pressure of the disks 405 and 505. This can prevent backflow of fluid in the opposite direction.

As shown in FIG. 5A, when the supply of the fluid is to be stopped or when the maintenance on the pipe is necessary, when the handle 517 is rotated, the lower end portion formed by bending the flow rate adjusting spindle 509 in a horizontal direction to be bent to one side is the disk 505. ) To stop the flow of fluid, which can completely stop the supply of fluid.

Single shaft cover fixing nut 416, 516, ring 411, 511, presser ring 414, 514, soft packing 412, 413, 512, 513 And the single shaft covers 410 and 510 are internal connection components of the one-touch check valve, among which the single shaft covers 410 and 510 are flow regulating to open and close the disks 405 and 505. As a component for the uniaxial structure generated due to the rotation of the spindle (409, 509), it functions to support the smooth rotation of the flow control spindle (409, 509).

6 is a pipe connection diagram of the one-touch check valve of the present invention. The projection hexagon nut 601 secures the pipe 619 to the one-touch check valve body 604. A flange portion or a flare portion is formed at the end of the pipe 619, a pipe fixing ring 602 is inserted into the pipe 619, and the projection hex nut 601 is inserted into the male screw of the one-touch check valve body 604. When fastened to the flange portion or the flare portion of the pipe 619, the pipe fixing ring 602 is pressed, the pipe 619 is in close contact with the one-touch check valve body 604. A soft ring 603 is inserted and installed between the pipe 619 and the one-touch check valve body 604. The pipe fixing ring 602 is positioned between the pipe 619 and the projection hexagon nut 601. It serves to stably support the one-touch check valve body 604 and the pipe 619, the soft ring 603 is located between the one-touch check valve body 604 and the pipe 619 to leak the fluid. To prevent it.

The combination of the projection hexagon nut 601, the pipe fixing ring 602 and the soft ring 603 as described above can be very easy to install the pipe, and during maintenance, only the connection part is dismantled to be easily maintained. Can be. That is, the connection between the pipe 619 and the one-touch check valve body 604 is separated by dismantling only the projection hexagon nut 601, so that the pipe 619 or the one-touch check valve is easily replaced or repaired in case of damage or damage. It is possible to do
