[0001] Containers of valve connection [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a valve to a composite container, in particular, to a composite container made by winding glass fiber around a synthetic resin (PE) container, Thereby preventing leakage of the gas due to the expansion coefficient generated by the thermal deformation in the structure in which the valve is connected and preventing the generation of water during gas discharge and charging to prevent corrosion, The present invention relates to a valve connection structure of a composite container which is provided with a release preventing cap and which can be used more stably.

Generally, liquefied petroleum gas (LPG) is obtained by refining crude oil, which is mainly composed of propane and butane, where propylene and butylene are added and then liquefied by pressurization. Such LPG is heavier than air, and therefore, when gas leakage occurs, it does not diffuse to the air, but it accumulates in the lower part of the place where leakage occurs, so that an explosion may occur due to static electricity or flame.

According to the conventional LPG container structure, the container to which the gas is charged is made of a metal material, and a container inlet is provided at an upper portion of the container, and the valve is directly connected to the container inlet.

In order to connect the valve to the inlet of the metallic material as described above, an anti-leak tape for preventing the leakage of gas is wound around the lower connection portion of the valve and screwed to the container inlet.

Such metal containers are heavy in weight and difficult to be transported. In particular, when the gas is filled or discharged into the container, moisture is generated at the inlet of the container coupled with the valve due to internal / external temperature and pressure. And corrosion of the portion where the valve is coupled due to moisture causes gas leakage frequently.

In order to solve the above-mentioned problem, recently, a container in which gas is stored is composed of a double container of an inner container and an outer container, wherein the inner container is made of a synthetic resin material (PE) It is used with a composite container.

A valve connector of a metallic material is assembled to the container inlet of the composite container, and then the valve connector is screwed directly to the connector by sealing the anti-tamper tape at the lower end of the valve, which is a conventional method, without sealing the valve connector.

As described above, there is a risk of corrosion due to the coefficient of thermal expansion when the protective tape is wound around without sealing, and a gap is generated between the composite container and the connector, thereby reducing the airtightness.

In order to solve the above-mentioned problem, it is urgent to provide an improved structure capable of combining the valve with the airtightness of the composite container.

Further, such a valve connector is held by the bolt, and a safety accident may occur due to vibration during the movement or loosening of the bolt. Thus, there is a need for an apparatus that can prevent the assembly unit from being loosened.

As shown in FIG. 1, the present invention includes a composite container 10 in which various gases are stored, a main connector 200 coupled to an upper end of the composite container, And a valve connector (100) for connecting the valve body.

The composite container is made of a container which is made of a synthetic resin (PE) container and a glass fiber wound around the outer periphery of the container, so that the container is durable and light in weight.

A container inlet is formed at an upper end of the composite container to facilitate discharge and filling of gas, and a valve body is connected to the container inlet.

On the other hand, an O-ring groove 11a is formed on the upper surface of the container inlet 11, and an O-ring 12 for holding the air-tightness is inserted into the O-ring groove.

The main connector 200 has a body 201 as an upper end and an elastic part 201 screwed to the container inlet 11 as a lower end of the body.

A bolt fastening hole 202 is formed on the upper surface of the body 201 in a cross shape so that the valve connector 100 is seated and fastened by the bolt B.

The elastic portion 201 formed at the lower end portion is configured to have a curved surface so that the lower end surface is seated on the seating surface 13 of the container inlet, and the seating portion is formed to be expanded and thinner toward the end so as to have an elastic force.

The inner side of the main connector 200 is formed with a coupling part 206 having a screw thread so that the lower end part of the valve connector 100 is assembled inward and the inner chamber 203 and the outer periphery of the container inlet 11 are screwed, do.

Since the main connector 200 is screwed to the outer periphery of the container inlet 11 and firmly holds the container inlet by the elastic force of the elastic portion 201 formed to be thinner toward the end when fully engaged, It is possible to suppress the deformation and the clearance caused by the above.

Meanwhile, the valve connector 100 is integrally formed with a body 101 at an upper portion and a coupling portion 104 at a lower end of the body to be assembled into a built-in chamber of the main connector.

A plurality of bolt fastening protrusions 102 are formed on the upper end of the body 101 so as to be assembled by the bolts B when assembled with the main connector.

At least one or more O-ring grooves 104a are formed on the outer periphery of the coupling portion 206, and O-rings 103 are assembled in the O-ring grooves.

The valve connector 100 constructed as described above is assembled by being fitted into the built-in chamber 203 of the main connector and assembled to the upper end of the main connector 200 by bolts. At this time, the lower end of the coupling part 104 assembled with the interior chamber is assembled by compressing the O-ring 12 provided at the upper end of the container inlet 11, so that the gap of the coupling part coupled to the upper end of the container inlet is eliminated, .

The O-ring 103 provided at the outer periphery of the coupling part is assembled to be in tight contact with the wall surface of the built-in chamber 203, and thus the airtightness is doubly maintained.

Thus, the airtightness of the upper end of the container inlet and the lower end of the coupling portion is maintained, and the side end of the coupling portion and the wall surface of the built-in chamber are hermetically sealed by the O-ring.

A valve body 30 is connected to the valve connector hole 106 of the valve connector 100. The valve connector body 31 is assembled with the valve connector hole 106 in a state in which a waterproof tape is wound on the valve body connector 31 .

As described above, in the composite container for reducing the weight and minimizing the water vapor generated when the gas is filled and discharged, the connection portion is deformed due to the thermal expansion coefficient when the valve body is connected, causing a gas leakage accident. However, When the valve body is connected, the deformation due to thermal expansion can be minimized and the airtightness can be maintained excellent.

The main connector 200 and the valve connector 100 are prevented from being loosened by fastening the bolts b to the bolt fastening protrusions 102 of the main connector 200 and the valve connector 100.

At this time, a loosening prevention cap 300 for preventing the loosening of the bolts is fastened to the bolt fastener 102 to which the bolt (b) is fastened.

By providing the release preventing cap 300, it is possible to prevent vibration due to transportation or loosening of an optional bolt.

The release preventing cap 300 is provided so as to be installed at each of the bolted portions (see FIG. 3).

As shown in FIG. 4, the release preventing cap 300 is also integrally formed to protect the valve connector while straddling the bolt more stably.

In order to protect the bolt (b) inserted in the shape of a cross, the anti-release cap (300-1) is formed in the shape of a cross. The central portion through which the connector (31) It is possible to prevent the bolt from loosening and to prevent deformation while protecting the valve connector.

As described above, according to the present invention, since the valve is assembled by using the main connector and the valve connector, deformation between the composite container and the connector due to thermal expansion can be prevented, and the airtightness due to the engagement can be maximized, And it is possible to prevent the bolts from being loosened by the bolt loosening cap, thereby providing a more stable gas container.
