Description

Fastening member assembly and pressure vessel having the same {CLAMPING MEMBER ASSEMBLY AND PRESSURE VESSEL HAVING THE SAME}

The present invention relates to a fastening member assembly comprising a fitting member rupturable by gunpowder and a pressure vessel having the same.

Pressure vessels are fluid vessels that store liquids or gases at high pressure without changing the volume, such as steam boilers, air tanks, hydraulic presses, and internal combustion engines.

The pressure vessel must be shut off from the outside of the inlet in order to receive a fluid having a pressure above atmospheric pressure in the interior space, and without such a block, the pressure of the fluid in the interior space is drastically reduced.

As a shutoff device for blocking the internal space of the pressure vessel from the outside, there is a cap type plug type having a locking device.

The pressure vessel opens the inlet of the pressure vessel as necessary to reduce the internal pressure of the pressure vessel, and one of such opening methods is a sudden opening to open the inlet of the pressure vessel at one moment.

The plug type requires the release of the lock to open the plug. In general locking devices, such as latching and bolting, the release of the locking device is performed sequentially, so there is a restriction when it is necessary to open the pressure vessel suddenly.

One object of the present invention relates to a pressure vessel having a tightening member assembly and a form different from the prior art.

Another object of the present invention is to implement a sudden release of the tightening member assembly and a sudden opening of the pressure vessel having the same through the fitting member rupturable by the gunpowder.

Yet another object of the present invention is to ensure that both the fastening and removal reliability of the fastening member assembly is high through the fitting member that is strong against external loads but is brittle even with a small amount of powder.

In order to achieve the object of the present invention, the tightening member assembly according to an embodiment of the present invention is a fitting member that can be ruptured by the gunpowder between both ends of the tightening member forming a circular band shape or can be close to each other. Is formed by fitting, and the fitting member supports a load acting between both ends of the tightening member. The pressure vessel having the tightening member assembly is provided with a stopper for coupling the inlet to the outside at an inlet which communicates the internal space of the pressure vessel body in the pressure-resistant environment with the outside, and the tightening member assembly is disposed in succession to the stopper, and the tightening member assembly is pressurized. The inner circumferential surface of the body defining the container inlet is pressurized directly or with a stopper to form a stopper.

According to an aspect of the present invention, the fitting member is an explosion induction part which is ignited so that the explosive may be exploded by being connected with an explosive gun and an explosive gun embedded in the fitting member body and the fitting member body positioned between both ends of the tightening member. Is done.

According to another aspect of the invention, the fitting member body may have at least part of a circular cross section.

According to another aspect of the invention, the fitting member body is extended to the assembly wing that can wrap one side of the tightening member.

According to another aspect of the invention, the tightening member may have a cross section having at least one inclined portion.

The present invention enables the fitting member fitted between the both ends of the tightening member to be rupturable by the gunpowder to realize the sudden release of the tightening member assembly and the sudden opening of the pressure vessel provided therewith.

According to the present invention, at least a part of the fitting member body has a circular cross section so that the explosive powder is embedded in the fitting member body, thereby mitigating or preventing leakage of the explosion pressure during explosion of the explosive powder.

The present invention extends the assembly wing that can wrap one surface of the tightening member to the fitting member body so that the fitting member can be positioned at a constant position between both ends of the tightening member.

Hereinafter, a tightening member assembly and a pressure vessel having the same according to the present invention will be described in more detail with reference to the accompanying drawings. In the present specification, the same or similar reference numerals are assigned to the same or similar configurations in different embodiments, and the description thereof is replaced with the first description.

1 is a front perspective view of a pressure vessel 100 having a tightening member assembly 200 according to one embodiment of the invention, and FIG. 2 is a tightening member assembly taken along line II-II of FIG. It is sectional drawing of the pressure container 100 provided with 200.

The main body 101 of the pressure vessel forming the appearance of the pressure vessel 100 may be formed as one body or two or more bodies are combined.

The body 101 of the pressure vessel may be formed of a metal material such as carbon steel for pressure vessel, or a fiber-reinforced composite material.

The main body 101 of the pressure vessel may be formed as, for example, a cylindrical vessel or a spherical vessel, and a fluid having a pressure above atmospheric pressure may be formed in the internal space of the pressure vessel 100 defined by the main body 101 of the pressure vessel. Can be accommodated.

The main body 101 of the pressure vessel is formed with an inlet 103 which communicates the inner space with the outside so that fluid can flow into the inner space, and a stopper 102 that blocks the inlet 103 of the pressure vessel from the outside is coupled. .

The stopper 102 is fixed by the fastening member assembly 200, and the fastening member assembly 200 includes a fitting member 220 (see FIG. 5) that is fitted between the fastening member 210 and both ends 213 of the fastening member. Include.

The belt-shaped tightening member 210 has a cross section having an inclined portion 210a as shown in the drawing, and an inner surface 104 of the pressure vessel 100 is inclined to correspond to the inclined portion 210a. Is formed.

The fastening member 210 is disposed on one surface of the stopper 102 to fix the stopper 102. The fitting member 220 is fitted between both ends 213 of the tightening member so that the tightening member 210 maintains its original shape.

Due to the fluid pressure in the inner space of the pressure vessel 100, the force to generate the cap 102 to the outside of the pressure vessel 100 is generated. This force is in close contact with the inclined portion 210a to the inclined groove portion 104a, and both ends of the fitting member 220 are subjected to a compressive load by the reaction force against such closeness. The fitting member 220 supports the compressive load so that the tightening member 210 is maintained in its original shape. This allows the stopper 102 to be fixed at the inner surface 104 of the pressure vessel 100.

When the fitting member 220 sandwiched between both ends 213 of the tightening member is ruptured by gunpowder, both ends 213 of the tightening member cannot support the compressive load. The tightening member 210 is moved toward the outside of the pressure vessel 100 along the inclined groove 104a of the pressure vessel 100. At the same time, both ends 213 of the tightening member are deformed to be close to each other. Due to the deformation of the fastening member 210, the stopper 102, which receives the fluid pressure of the pressure vessel 100, is not fixed and is opened.

Since the opening of the pressure vessel 100 is made by the bursting of the fitting member 220 and the fluid pressure in an instant, the rapid opening of the pressure vessel 100 can be realized.

3 is a cross-sectional view of another embodiment of a pressure vessel 100 ′ having a tightening member assembly 200 (see FIG. 1 below) taken along line III-III of FIG. 1.

 The tightening member 210 'is opened toward the inner surface 104' of the body defining the inlet 103 'by the fitting member 220 which is fitted between both ends 213 of the tightening member.

The tightening member 210 opened by the fitting member 220 is in close contact with the inner surface 104 ′. By such close contact, the frictional resistance to the force that the stopper 102 'tries to escape to the outside of the pressure vessel 100' is generated by the fluid pressure in the internal space of the pressure vessel 100 '. The stopper 102 'is fixed to the inlet 103' of the pressure vessel so as to block the internal space of the main body from the outside by the frictional resistance.

When the fitting member 220 sandwiched between both ends 213 of the tightening member is ruptured by the gunpowder, the tightening member 210 'is rapidly deformed in the direction of restoring to its original shape. The deformation of the fastening member 210 'causes a gap between the fastening member 210' and the inner circumferential surface 104 'of the pressure vessel. This causes the stopper 102 'of the pressure vessel 100' to open to open the pressure vessel 100 '.

Hereinafter, the tightening member assembly 200 will be described in more detail with reference to the accompanying drawings. In the embodiments described below are described based on the tightening member assembly 200 and the pressure vessel 100 having the same for the sake of simplicity, the application to various forms, such as the pressure vessel (100 ') shown in FIG. It is possible.

The tightening member 210 included in the tightening member assembly 200 may have a circular band shape in which both ends 213 may be separated from each other.

The fastening member 210 may be formed using a non-metallic material such as synthetic resin, but is preferably formed to have a metal material that is elastically deformable, such as spring steel.

A fitting member 220 that can be broken by gunpowder is sandwiched between both ends 213 of the tightening member. The fitting member 220 may support a load acting between both ends 213 of the tightening member.

Both ends 223 of the fitting member 220 may be formed in a shape corresponding to both ends 213 of the tightening member so that a larger area is in contact with both ends 213 of the tightening member. By contacting a large area, the load of the fastening member 210 applied to the fitting member 220 may be dispersed.

The fitting member 220 is formed by a fitting member body 221 positioned between both ends 213 of the tightening member, and the explosion member 230 may rupture the fitting member 220 in the fitting member body 221. It is built.

The fitting member body 221 is formed of a material having high compressive strength and relatively low toughness, for example, nodular graphite cast iron or the like. This is to resist the compression applied by the tightening member 210, but to rupture finely by the gunpowder.

The fitting member body 221 is formed to have at least part of a circular cross section. This circular cross section has a sealed structure for the explosive powder 230 so that the explosion pressure does not escape to the outside and is used to deform or break most of the fitting member body 221. As a result, a fitting member having excellent bursting properties can be designed even with a small amount of powder.

The fitting member body 221 supports the compressive load acting between both ends 213 of the tightening member.

The circular cross section has a high strength against compressive load, thereby improving the structural stability of the tightening member assembly 200, thereby increasing the structural stability of the pressure vessel 100 (see FIG. 1).

The explosive powder 230 is formed using, for example, a Detonation Fuse to explode the explosive at about the same time. Preferably, the fitting member 220 is miniaturized by using a MDF (Mild Detonation Fuse) which is generally used as an elongated width line.

The explosive powder 230 is formed by embedding the gunpowder 231 in the outer tube 232. Tube 232 may be an aluminum or lead tube generally used as MDF tube and gunpowder 231 may be a RDX and the like commonly used as the main material of military bombers.

The explosive powder 230 is connected to at least one explosion-inducing unit 240 capable of igniting the explosive powder 230 to explode.

The explosive induction part 240 includes an explosive induction powder 242 and an explosion induction part case 243. Explosive induction powder 242 may be, for example, RDX.

The explosive induction powder 242 surrounds a part of the explosive powder 230 and is embedded in the explosion induction part case 243 to protect the explosive induction powder 242 from an external impact.

The explosion of the explosive powder 230 induced by the explosion in the explosive-induced explosives 242, even if a small amount of explosives 231 of the explosive explosives 230 has high explosion reliability.

A filler 241 may be filled between the explosive-induced explosive 242 and the explosive-explosive 230 to help with moisture, corrosion, and the like of the explosive explosive 230.

The filler 224 serves to fill an empty space that prevents the explosion of the explosive-induced explosive 242 from being delivered to the explosive explosive 230. For example, a material having weak toughness or strength such as epoxy is used.

The explosion guide 240 may ignite an ignition device, such as a separate squib or a general electric detonator, against the explosion guide 240 to ignite and explode.

The fitting member body 221 has an assembly wing 222 which can cover one surface of the tightening member 210 is extended.

The assembly wing 222 is positioned at a predetermined position with respect to the direction in which the fitting member 220 is fitted in contact with one surface of the tightening member 210 when the fitting member 220 is inserted between both ends 213 of the tightening member. To catch.

The assembly wing 222 is formed to surround one surface of the tightening member 210 and the rotation of the fitting member body 221 with respect to the X axis, which is the central axis of the fitting member body 221, and the Y-axis direction (in particular, (-) direction). The movement of the fitting member body 221 is constrained.

The tightening member 210 and the fitting member 220 may be coupled by bolting the hole 212 of the tightening member 210 and the hole 225 of the assembly wing 222.

By the bolt fastening, the movement of the fitting member body 221 is completely restrained.
