Description

ADAPTER SUPPORT DEVICE OF VALVE ASSEMBLY

The present invention relates to an adapter support device for a valve assembly.

As is well known, the valve is connected between pipes through which fluid is transferred. The user can operate the valve to block or open fluid flow between pipes connected to both sides of the valve.

Valves are available in a variety of forms, among which are flanged valves.

The flange valve is provided with flanges on both sides, and pipes are connected through each flange. In addition, a ball-shaped valve body is built in between the flanges, and the opening and closing functions of the valve are exerted by its operation.

However, in the case of a flange valve made of such a material, there may be a problem regarding durability during use, and in particular, there may be a risk of whitening and damage to the flange portion, and thus it is necessary to develop a technology to prevent this.

The whitening phenomenon is a phenomenon caused by physical changes. In plastic, polymer chains are entangled with each other, but when the force is deformed, the polymer chains change their position, resulting in changes in volume and appearance. In the process, a thing that has amorphousness is crystallized and whitening occurs. This is called a whitening phenomenon.

In other words, the cause of whitening is caused by excessive fastening of the flange valve, but when tightening the bolt with a stronger torque value, the flange portion may be damaged and a serious problem may occur.

As a specific example, when tightening the bolts, whitening may occur due to the imbalanced tightening of the diagonal side by tightening a lot of symmetrical bolts. In addition, the gap between the flange and the flange is insufficient, or due to the thickness of the flange adapter, uneven tightening may occur when bolting, which may cause whitening. In addition, due to elasticity of the product, that is, a localized load concentration phenomenon of the bolt fastening portion, the bolt fastening portion may be locally deformed to cause whitening.

As described above, in the case of a flange valve made of a material such as PP, there are many problems such as improvement in reliability as well as whitening, and thus technical efforts are required to solve this.

As a prior art related to the present invention, there is Korean Registered Utility Model Publication No. 20-0209164 (announced on January 15, 2001), and the flange adapter is disclosed in the prior art. However, the flange adapter disclosed in the prior art is a technique for preventing the pipe from being pushed by pressure by fixing the pipe in a position with a spike, and has not disclosed anything about solving the whitening phenomenon of a flange valve made of a material such as PP. not.

As shown, the valve assembly 100 including the adapter support device according to the embodiment of the present invention includes a flange valve 110, an adapter 130, a support 200.

The flange valve 110 includes a ball valve body 111 and a flange portion 115 provided at both ends of the ball valve body 111.

The ball valve body 111 is a configuration that controls the opening and closing of the flow of fluid by user manipulation of the separately provided lever portion 113, and may be formed in the same form as the conventionally known ball valve.

A pair of flange portions 115 may be provided at both ends of the ball valve body 111.

A pipe may be connected to each of the pair of flange portions 115.

The adapter 130 refers to a member that is connected to the flange portion 115.

Meanwhile, at least the flange portion 115 in the above-described flange valve, that is, the valve assembly 100 may be made of polypropylene (PP) material.

In the case of a valve made of polypropylene (PP) material, whitening may occur if excessive force is applied when tightening the bolt.

The whitening phenomenon is a phenomenon caused by physical changes, and plastic chains such as PP are entangled with each other, but when the force is deformed, the polymer chains change their position, resulting in changes in volume and appearance. In the process, it means a phenomenon in which an amorphous substance becomes crystallized and becomes white.

As a specific example, when tightening a lot of symmetrical bolts when tightening the bolts, whitening may occur due to unbalanced tightening of the diagonal sides. Alternatively, if the gap between the flanges is insufficient or the thickness of the flange adapter is not uniform, uneven tightening is caused when the bolt is tightened, and whitening may occur. In addition, the bolt tightening portion may be deformed due to local load concentration phenomenon of the bolt fastening portion, and whitening may occur.

In order to prevent such whitening, the support 200 is inserted between the flange portion 115 and the adapter 130.

As a specific example, the support 200 may be made of a material including at least one of polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), and polycarbonate (PC).

The flange portion 115 and the adapter 130 are fastened using bolts (not shown).

Specifically, the bolt passes through the bolt fastening portion 132 of the adapter 130, and then in turn passes through the circular hole 210 of the support 200 and the bolt fastening portion 310 of the gasket 300 in turn, It is fastened through the bolt fastening portion 116 of the flange portion 115. And the protruding end of the bolt can be fixed by a nut (not shown).

Therefore, as shown in FIG. 4, the bolt fastening part 132 of the adapter 130, the circular hole 210 of the support 200, the bolt fastening part 310 of the gasket 300, and the flange part 115 The bolt fastening portions 116 are formed at positions corresponding to each other. And these can be made in the form of a hole having a size and shape that the bolt can be fastened.
