Description

Valve device and hydrogen supply device including the same {VALVE APPARATUS AND HYDROGEN SUPPLY APPARATUS HAVING THE SAME}

The present invention relates to a valve device that selectively allows fluid to flow through a valve and reduces shock generation when the valve is operated, and a hydrogen supply device including the same.

Electric mobility is mobility that obtains its driving energy from electrical energy rather than from the combustion of fossil fuels like existing mobility. Electric mobility has the advantage of having no exhaust gases and making very little noise, but it has not been put into practical use due to problems such as the heavy weight of the battery and the time it takes to charge. However, recently, problems such as the worsening of pollution problems and depletion of fossil fuels have been raised. That development is accelerating again.

In particular, fuel cells are applied to provide electric energy for eco-friendly electric mobility, and the area of use of fuel cells is gradually expanding as a highly efficient, clean energy source.

Among these fuel cells, the polymer electrolyte membrane fuel cell (PEMFC) operates at a relatively low temperature compared to other types of fuel cells, has a short start-up time, and has quick response characteristics to load changes.

Additionally, polymer electrolyte fuel cells have high efficiency and high current density and power density. Additionally, it is less sensitive to pressure changes in the reaction gas (hydrogen and oxygen in the air) and can produce a wide range of output. For this reason, it can be applied to various fields such as a power source for pollution-free mobility, self-generation, mobile, and military power.

A polymer electrolyte membrane fuel cell is a device that generates electricity by electrochemically reacting hydrogen and oxygen to produce water. The supplied hydrogen is separated into hydrogen ions and electrons in the anode catalyst, and the separated hydrogen ions pass through the electrolyte membrane. It passes to the cathode. At this time, oxygen in the air supplied to the cathode combines with electrons entering the cathode through an external conductor to generate water and generate electrical energy.

Meanwhile, in order to obtain the necessary potential in an actual vehicle or drone, unit cells must be stacked to the required potential, and the unit cells stacked in this way are called a stack (or fuel cell stack). The potential generated from one unit cell is approximately 1.2V, and the power required for the load is supplied by stacking multiple cells in series. Each unit cell includes a membrane electrode assembly (MEA: Membrane Electrode Assembly), an anode to which hydrogen is supplied on both sides across a polymer electrolyte membrane through which hydrogen ions are transferred from the membrane electrode assembly, and a cathode to which air (oxygen) is supplied. Electrodes are provided. In addition, a gas diffusion layer is disposed on the outside of the anode electrode and cathode electrode including the catalyst layer, and a fuel cell stack is a sequential stacking of such a membrane electrode assembly and a separator plate on which reaction gas and coolant channels are formed.

In the operation of these fuel cells, a stable supply of hydrogen gas is an important operating factor. In particular, a plurality of fuel cells may be deployed in an actual vehicle or drone, and a uniform supply of hydrogen gas at a constant pressure to each fuel cell is required.

Accordingly, a valve device that regulates the supply of hydrogen gas is provided, but in the case of the valve device, there is a problem in that shock noise is generated due to the operating force as it is operated in a state filled with hydrogen gas.

The impact generated when operating such a valve device not only generates noise but also causes damage to each part, including the valve.

The matters described as background technology above are only for the purpose of improving understanding of the background of the present invention, and should not be taken as acknowledgment that they correspond to prior art already known to those skilled in the art.

Let's look at a preferred embodiment of the valve device according to the present invention and the hydrogen supply device including the same with reference to FIGS. 1 to 7.

The valve device according to the present invention includes a valve body (100) in which a distribution space through which fluid flows is formed, a core part formed with an inflow and outflow path through which fluid flows into the distribution space, and a stator provided outside the core part; A valve member 200 that is movably provided in the distribution space of the valve body 100 and has a guide hole 210 communicating with the distribution space. And in the distribution space of the core part, it is moved by a stator and selectively contacts the valve member 200, thereby opening and closing the guide hole 210 of the valve member 200 to allow fluid to selectively distribute through the guide hole 210. , a mover provided with a stopper portion (114a) manufactured integrally by injection molding at one end (114-1) facing the core portion in the moving direction and the other end portion (114-2) facing the valve member 200. (114); Includes.

In this way, a distribution space (S1) is formed in the valve body (100), and as the valve member (200) moves in the distribution space (S1), fluid is selectively distributed according to the position of the valve member (200). That is, a guide hole 210 is formed in the valve member 200, and the guide hole 210 is opened or closed depending on the position of the mover, so that the distribution space (S1) is distributed according to the position of the valve member 200. The fluid is distributed to the outside through the guide hole 210 of the valve member 200. Here, the fluid can be hydrogen.

In particular, the distribution space (S1) is provided with a locking portion 113 that prevents the valve member 200 from leaving, and the valve member 200 is formed to surround the guide hole 210, but the locking portion 113 A support part 220 is formed that extends to a part matching the fluid sealing part and absorbs shock when in contact with the locking part 113.

That is, the valve body 100 is formed with a locking portion 113 extending into the distribution space (S1), thereby restricting the movement of the valve member 200 moving in the distribution space (S1) when it contacts the locking portion 113. do. Accordingly, the valve member 200 is moved in the distribution space (S1), but its movement is limited only to the position where the catching portion 113 is formed, thereby preventing it from leaving the distribution space (S1), and the movement position is regulated as the movement distance is regulated. The opening or closing operation of the guide hole 210 can be accurately performed.

In this way, the mover 114 is provided with stoppers at one end 114-1 and the other end 114-2, so that when the mover 114 moves to one side and contacts the core portion 110, one end 114 As the stopper part 114a provided in -1) contacts the core part 110, the contact shock is canceled out, and the mover 114 moves to the other side and when it contacts the valve member 200, the other side end 114-2 ) As the stopper portion 114a provided in contacts the valve member 200, the contact shock is canceled out. In addition, in the case of the stopper portion 114a provided at the other end 114-2 of the mover 114, as it matches with the guide hole 210 of the valve member 200, the mover 114 is connected to the valve member 200. When contacted, the guide hole 210 is closed by the stopper portion 114a, thereby restricting the flow of fluid.

Each of these stopper parts 114a may be made of a rubber material, and the stopper part 114a provided at one end 114-1 of the mover 114 is larger than the one end 114-1 of the mover 114. The stopper portion 114a, which may be formed to protrude and is provided on the other end 114-2 of the mover 114, is formed to be linearly or concavely recessed with respect to the valve member 200. Airtightness can be ensured by closing the guide hole 210 upon contact.

Accordingly, the valve member 200 is formed so that one end 200-1, which is the entrance side of the guide hole 210, protrudes in one direction, and the stopper portion provided on the other end 114-2 of the mover 114 As it comes into close contact with (114a), the airtight performance of the guide hole 210 by the stopper portion (114a) can be improved.

The stopper part 114a made of rubber can be manufactured by inserting the mover 114 into the injection mold of the stopper part 114a and injecting the stopper part 114a.

By manufacturing the stopper part 114a through such insert injection, the stopper part 114a and the mover 114 can be formed as one piece, and the process of combining the stopper part 114a with the mover 114 during the conventional manufacturing process By deleting , there is an effect of simplifying the manufacturing process and reducing costs.

This stopper part 114a has a connection part 114a' that penetrates the mover 114 and connects the stopper part 114a of one end 114-1 and the stopper part 114a of the other end 114-2. may be included.

As shown in FIG. 2, the stopper portion 114a includes a connection portion 114a that penetrates the mover 114 and connects the stopper portion of one end 114-1 and the stopper portion 114a of the other end 114-2. ') is formed, which has the effect of improving the fastening force between the stopper portion 114a and the moving yarn.

The connection portion 114a' is formed together during injection molding of the stopper portion 114a and connects the stopper portion 114a of one end 114-1 and the stopper portion 114a of the other end 114-2 to connect the mover 114. ) can be molded integrally with.

A passage through which the connection portion 114a' passes may be formed in the mover 114, and the connection portion 114a' may be injected at the same time as the stopper portion 114a is injection molded after the mover 114 is inserted into the injection mold. It is molded and connected to the stopper part 114a of one end 114-1 and the stopper part 114a of the other end 114-2 to form the stopper part 114a integrally, and the mover 114 and the stopper are formed. There is an effect of improving the fastening force of the portion 114a.

A convex portion 114a'' protruding outward may be formed on one end 114-1 or the other end 114-2 of the stopper portion 114a.

As shown in FIG. 4, a protrusion protruding outward may be formed on one end 114-1 or the other end 114-2 of the stopper portion 114a. The stopper part 114a can be made of a louver material by injection molding. During injection molding, the stopper part 114a is injected larger than the part where it is coupled to the moving part, and shrinkage occurs during cooling. This may cause protrusions to form.

The protrusion formed through this has the effect of alleviating impact when one end 114-1 and the other end 114-2 contact the outside when the mover 114 moves in the vertical direction.

Meanwhile, a separation space (S2) is formed between the core portion 110 and one end 114-1 of the mover 114, and a slit hole 114b is penetrated in the longitudinal direction of the mover 114 to form a separation space ( S2) and distribution space (S1) may be connected.

As can be seen in FIG. 1, a separation space S2 is formed between the core portion 110 and one end 114-1 of the mover 114. Here, even if the mover 114 is completely moved to one side, the core portion 110 and the mover 114 are spaced apart by the stopper portion 114a provided at one end 114-1 of the mover 114. A space (S2) is formed.

In addition, a slit hole (114b) penetrates the mover 114 in the longitudinal direction so that the separation space (S2) and the distribution space (S1) communicate with each other. As a result, the fluid flowing in from the inflow passage 111 of the core portion 110 passes through the slit hole 114b in the distribution space S1 and is distributed to the separation space S2, so that the fluid flows into the separation space S2. It can be filled.

In this way, the fluid also circulates in the separation space (S2) between the core portion 110 and one end 114-1 of the mover 114, so that the movement of the mover 114 is supported by fluid pressure and the mover 114 The magnetic force required when moving is reduced. That is, when the guide hole 210 is closed as the mover 114 moves to the other side and comes into contact with the valve member 200, fluid fills the space S2 through the slit hole 114b of the mover 114. The force that moves the mover 114 to the other side is supported. Conversely, when the mover 114 moves to one side and leaves the valve member 200, the guide hole 210 of the valve member 200 is opened and the fluid flows, so the fluid remaining in the separation space (S2) is also taken. By being discharged through the guide hole 210 of the valve member 200, the force by which the mover 114 moves to one side is reduced.

Meanwhile, if the valve member 200 is described in detail, a wing portion 230 extending to be caught by the locking portion 113 is formed on the outer peripheral surface of the valve member 200.

That is, when the valve member 200 moves to the other side, the wing portion 230 is caught by the locking portion 113 of the valve body 100, thereby preventing it from leaving the distribution space (S1) and the position where the locking portion 113 is formed. Movement is restricted until.

Here, the core portion 110 is formed to surround the valve member 200 so that the valve member 200 moves only to one side and the other side, but the portion corresponding to the wing portion 230 of the valve member 200 is an empty space. By forming the valve member 200 to one side and the other side, the movement is limited only to the position where it contacts the locking portion 113 or the core portion 110.

In one embodiment of the present invention, when the mover 114 is moved and comes into contact with the valve member 200, the valve member 200 is pressed by the mover 114 and moved to the other side, and the wing portion 230 is a locking portion. It is supported by contacting (113). Because of this, the mover 114 can maintain the guide hole 210 of the valve member 200 in a closed state.

Here, the valve member 200 of the present invention has a support part 220 formed on the other end 200-2, which is the outlet side of the guide hole 210, and the support part 220 is formed around the guide hole 210. By being formed to surround part or the entire wing portion 230, contact shock is reduced as the support portion 220 contacts the locking portion 113.

In this way, the support portion 220 is formed at the other end portion 200-2 of the valve member 200, and extends to surround part or the entire other side of the wing portion 230 around the guide hole 210, so as to cover the valve member 200. When the member 200 moves and contacts the wing portion 230 and the locking portion 113, the support portion 220 is interposed between the wing portion 230 and the locking portion 113 to absorb shock. As a result, when the valve member 200 moves toward the locking portion 113, the support portion 220 comes into contact with the locking portion 113, thereby canceling out the shock and making the area around the outlet side of the guide hole 210 airtight. Leakage of fluid is prevented.

Meanwhile, the other end portion 200-2 of the valve member 200 includes an edge portion 241 forming an outer surface, a step portion 242 surrounding the outlet of the guide hole 210 on the inside of the edge portion 241, and , It is recessed on one side from the step portion 242 and consists of a support portion 243 spaced apart from the edge portion 241.

As shown in FIG. 4, the other end portion 200-2 of the valve member 200 has a step portion 242 surrounding the outlet of the guide hole 210 on the inside of the edge portion 241 forming the outer surface. By forming a support portion 243 that is recessed on one side of the chin portion 242, the support portion 220 can be filled between the edge portion 241 and the step portion 242 and between the edge portion 241 and the support portion 243. . In this way, the support part 220 is filled on the side of the step part 242 and the support part 243 on the inside of the edge part 241, so that the lateral movement of the support part 220 is limited and the coupled state can be maintained. .

Here, the outer surface of the stepped portion 242 is formed to gradually become narrower in width toward the support portion 243.

In this way, the stepped portion 242 is formed to be inclined as the width of the outer surface becomes narrower toward the support portion 243, thereby preventing the support portion 220 filled between the edge portion 241 and the stepped portion 242 from being separated. do. That is, as the support portion 220 is formed to surround the side of the step portion 242, it is caught on an inclined portion of the step portion 242 and is prevented from leaving to the other side, and a solid fixed state can be maintained.

Meanwhile, an insert passage 244 extending between the edge portion 241 and the support portion 243 to the position of the wing portion 230 is formed in the other end portion 200-2 of the valve member 200, and the insert passage 244 An insert hole 245 penetrating toward the wing portion 230 is formed.

The insert flow path 244 and the insert hole 245 are for forming the support portion 220 on the other end 200-2 of the valve member 200, and are formed through the insert flow path 244 and the insert hole 245. The support portion 220 can be injection molded.

This insert flow path 244 passes in a straight line between the edge portion 241 and the step portion 242 and the edge portion 241 and the support portion 243 at the other end portion 200-2 of the valve member 200. It extends to the position of the wing portion 230. Accordingly, when filling the support portion 220 through the insert flow path 244, the support portion 220 may be formed to fill the sides of the stepped portion 242 and the support portion 243.

Additionally, the insert hole 245 penetrates the edge portion 241 at the position of the wing portion 230 and communicates with the insert flow path 244. For this reason, when molding the support portion 220 on the valve member 200, the support portion 220 may be formed to extend to the wing portion 230 through the insert hole 245.

Here, the insert hole 245 may extend to be recessed in the outer surface of the support portion 243 after passing through the edge portion 241 and the insert flow path 244. That is, the insert hole 245 extends to be recessed in the outer surface of the support part 243, so that the support part 220 filled through the insert hole 245 can be more firmly fixed to the outer surface of the support part 243. In addition, as the support portion 220 extends from the wing portion 230 through the insert hole 245 to the recessed portion on the outer surface of the support portion 243, shock absorption performance is improved.

Meanwhile, the support portion 220 is formed to be longer on the other side than the edge portion 241 and the step portion 242 and protrudes from the other end portion 200-2 of the valve member 200 to the other side. In this way, the support part 220 is formed to protrude from the other end 200-2 of the valve member 200 to the other side, so that when it comes into contact with peripheral parts of the valve member 200, it becomes airtight through the support part 220. Performance is secured. In addition, the support portion 220 is formed to be longer on the other side than the edge portion 241 and the step portion 242, so that it surrounds the periphery of the guide hole 210, and when in contact with surrounding components, the protruding portion of the support portion 220 The parts adhere closely together, improving airtightness.

In this way, when injection molding the support part 220 through the insert flow path 244 and the insert hole 245, the step part 242 and the support part 243 are formed to the inside of the edge part 241 through the insert flow path 244. In addition to filling the side of the support part 220, the support part 220 extends to the other side of the wing part 230 through the insert hole 245, so that the support part 220 is attached to the valve member 200. It is firmly coupled to each other, and a sealing function by wrapping around the guide hole 210 and a shock absorption function by covering the wing portion 230 can be implemented.

In the valve device according to the present invention described above, as shown in FIG. 2, when the mover 114 is moved to the other side, the stopper portion 114a provided on the mover 114 contacts the valve member 200 and the stopper portion As (114a) closes the guide hole 210, the flow of fluid is blocked. At this time, the valve member 200 is moved downward by the mover 114, and the impact is canceled out as the support part 220 surrounding the wing part 230 contacts the locking part 113 of the valve body 100. As a result, impact noise is also reduced.

Meanwhile, as shown in FIG. 3, when the mover 114 is moved to one side, the stopper portion 114a provided on the mover 114 is spaced apart from the valve member 200, thereby opening the guide hole 210. It may have an operation relationship that allows fluid to flow through the guide hole 210.

Meanwhile, as shown in FIG. 5, the hydrogen supply device including the valve device according to the present invention has an inlet 310 where a hydrogen tank A1 is connected and hydrogen is supplied, and hydrogen is discharged and a fuel stack A2. It includes a housing 300 provided with an outlet 320 to which is connected, and the valve device is connected in communication with the inlet 310 in the housing 300 to selectively allow the distribution of hydrogen.

As shown in FIG. 6, a mounting portion 330 is formed on the inlet portion 310 side of the housing 300, and the valve device is detachably installed on the mounting portion 330 to configure the valve device in the housing 300. can do. At this time, the valve device may be bolted for ease of assembly, and as the valve device is configured to be detachable from the housing 300, maintainability and assembly of the valve device are improved.
