Description

Pipe connection device using cap saddle and adapter and piping connection method using the same}

The present invention relates to a pipe connection device using a cap saddle and an adapter, and a pipe connection method using the same.

In general, for living infrastructure such as houses and roads, pipes for water supply and sewage and wastewater treatment for drinking water supply are buried underground to supply necessary contents.

Such piping work is to form a buried pipe for water and sewage by digging the ground using heavy equipment such as an excavator or a fork lane, and then arrange a line or several lines of pipes of a specified standard into the buried pipe, and then connect the pipes by manpower (hereinafter It is referred to as "jointing" in the following.) It is finished by refilling the excavated ground after performing the work.

Here, the joint operation is a work for the purpose of preventing leakage as well as increasing the assemblability and durability of the pipe connection, and a representative method includes a permanent coupling method such as a welding joint and a solder joint. In addition, there are disassembly and coupling methods, such as a flange joint that flanges the pipes together, a screw joint using a screw connection method, and an expansion joint using an expansion pipe.

Among these disassembly and coupling methods, the flange joint is made of an upper flange 10 and a lower flange 20, as viewed with reference to FIGS. 1 and 2. The upper flange 10 includes a flange 11, a circulation groove 13, and a screw groove 15, and the lower flange 20 is a flange 21, a circulation groove 23, and a screw groove 25. , The shaft (27), it is configured to include a cap (29). Here, the configurations of the upper flange 10 and the lower flange 20 described above are only an example, and such configurations may be changed in design.

And in the space between the flanges (11, 21), paper, synthetic resin, hemp, rubber, asbestos, leather, copper, asbestos, leather, copper, and so on to maintain the pressure of the pipes (100a, 100b) while maintaining the airtightness of the contact surface between the flanges (11, 21). A gasket (not shown) made of at least one of leaded mild steel may be inserted.

In addition, the flanges 11 and 21 may be made of a blind flange. Here, the blind flange refers to a flange whose inner diameter is closed, and the circulation grooves 13 and 23 are formed so that the fluid flowing from the first pipe 100a to the second second pipe 100b is circulated. This blind flange has the advantage of preventing fluid leakage as the inner diameter is closed. On the other hand, the flange saddle may be coupled between the upper flange 10 and the lower flange 20, the blind flange (not shown) is configured separately, unlike shown in Figs.

Such a flange joint using a flange saddle is a method of joint work that is widely used in that it is possible to connect between relatively easy and relatively rigid flanges.

However, since the flange joint has to be coupled to the flanges 11 and 21 through fastening between the screw grooves 15 and 25 formed in plural and a plurality of bolts (not shown), a skilled worker for fastening must be introduced. There is a problem in that a large amount of labor costs are expended.

In addition, the flange joint has a problem in that there is always a risk of a leak that may cause leakage due to incomplete coupling or damage between the flanges 11 and 21.

In addition, in order to insert a gasket (not shown) between the flanges 11 and 21, the upper flange 10 and the lower flange 20 must be aligned and spaced a certain distance apart from each other, but the upper flange 10 and the lower When the flange 20 is provided in a large size, it is difficult to align the upper flange 10 and the lower flange 20 in a state spaced apart by a predetermined distance.

Accordingly, there is a need to develop a device capable of preventing fluid leakage by removing the risk of leakage while being simpler than a flange joint and reducing the cost of the joint process.

Piping connection method

First, the cap saddle 200 and the adapter 300 are injection-molded (S10).

Specifically, the fusion portion 213 of the saddle 210, which is a configuration included in the cap saddle 200, and the second pipe 100b are fused. Here, the second pipe 100b is a pipe for draining the fluid to the outside from the first pipe 100a to be described later.

After step S20, the cap 220 is separated from the saddle 210 (S30). This step S30 proceeds when the fluid circulating along the first pipe 100a needs to be drained through the second pipe 100b. That is, step S30 is performed when indirectly connecting the first pipe 100a and the second pipe 100b.

After step S30, the adapter 300 is inserted into the saddle 210 (S40). Specifically, after separating the cap 220 from the saddle 210, the coupling part 320, which is a component included in the adapter 300, is inserted into the saddle 210.
