Description

Technology Field

[0001] The present invention relates to a hydrogen regulator, and more specifically, to a hydrogen regulator that regulates the pressure of hydrogen used as fuel for a vehicle. Background Technology

[0002] In general, the carbon-neutral green technology campaign aims to reduce greenhouse gases below an appropriate level by lowering dependence on fossil fuels, expanding the use and distribution of clean energy, and increasing the research and development of green technologies and carbon sinks.

[0003] The recent increase in international interest in carbon-neutral green technology is due to the fact that fossil fuels such as oil and coal are recognized as the main culprits of global warming, leading to a heightened awareness of the need to curb fossil fuel use, develop alternative energy, and conserve and improve energy efficiency from an environmental perspective, as well as the serious recognition of the energy crisis from an economic perspective due to the sense of crisis caused by the depletion of fossil fuels and the surge in oil prices.

[0004] As an example of the practical guidelines for the aforementioned carbon-neutral green technology campaign, hydrogen fuel cell vehicles utilize electrical energy generated through the chemical reaction between oxygen and hydrogen in a stack as a power source. Since these vehicles can continuously generate power regardless of cell capacity by supplying fuel and air from an external source, they offer the advantages of high efficiency and virtually no pollutant emissions; consequently, technological development of such hydrogen fuel cell vehicles has been actively underway recently.

[0005] The above-described hydrogen fuel cell vehicle is equipped with one or more hydrogen tanks filled with high-pressure hydrogen gas. The hydrogen fuel filled in the hydrogen tanks is supplied to the stack via a high-pressure regulator and a low-pressure regulator.

[0006] Korean Patent Publication No. 10-2286442 (August 5, 2021) (hereinafter referred to as the "prior art") discloses a "high-pressure regulator."

[0007] The above-described prior art has an inlet port and an outlet port coupled to the circumference of an upper body, and a valve is installed inside the upper body to open and close a flow path between the inlet port and the outlet port so as to be movable up and down, and a piston is installed on the upper side of the valve to press the valve downward by the elastic force of a spring.

[0008] In the above prior art, when the pressure of the gas introduced into the interior of the upper body through the inlet port becomes higher than the elastic force of the spring, the piston opens the flow path between the inlet port and the outlet port, and the gas is discharged through the outlet port.

[0009] However, the above-mentioned conventional technology had a problem in that the protrusions formed at the center of the lower surface of the piston and the center of the upper surface of the valve, respectively, were in contact with each other inside the seat, and thus the protrusions wore out during the process of the piston repeatedly moving up and down to open and close the flow path between the inlet port and the outlet port for a long time, resulting in poor operation.

[0010] In addition, the above-mentioned conventional technology had the problem that it was difficult to install inside the upper body and lower body because the valve and the components for operating the valve, such as the seat, the second spring, and the spring guide, were composed of separate parts.

[0011] In addition, the above-mentioned conventional technology had a problem in that it could not easily control the pressure of the gas introduced into the interior, because it opens and closes the flow path between the inlet port and the outlet port solely by the pressure of the gas introduced into the interior of the upper body through the inlet port. Prior art literature

[0012] Korean Patent Publication No. 10-2286442 (August 5, 2021) The problem to be solved

[0013] The problem that the present invention aims to solve is to provide a hydrogen regulator in which a valve stem for operating a pressure reducing valve is inserted and disposed within the pressure reducing valve, thereby ensuring smooth operation of the pressure reducing valve even after prolonged use.

[0014] Another problem that the present invention aims to solve is to provide a hydrogen regulator that is easy to install within a body by installing the components constituting the pressure reducing valve within the valve housing to form the pressure reducing valve into a single assembly.

[0015] Another problem that the present invention aims to solve is to provide a hydrogen regulator that can easily control the pressure of hydrogen introduced into the hydrogen flow path by installing a pressure reducing valve operated by the pressure of hydrogen and an electronically operated solenoid valve to open and close a hydrogen flow path extending from a hydrogen inlet to a hydrogen outlet.

[0016] The problems of the present invention are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below. means of solving the problem

[0017] To achieve the above objective, a hydrogen regulator according to the present invention comprises a body and a pressure reducing valve. A hydrogen flow path extending from a hydrogen inlet to a hydrogen outlet is formed inside the body. The pressure reducing valve is installed in the hydrogen flow path within the body and opens or closes based on the pressure of the hydrogen. A valve stem for operating the pressure reducing valve is arranged within the pressure reducing valve so as to be movable up and down.

[0018] The above pressure reducing valve may comprise a valve housing, a valve member, and an elastic member. The valve housing may be installed in the hydrogen flow path. An internal space extending vertically from the top to the bottom may be formed in the valve housing. The valve member is positioned to be movable vertically within the internal space of the valve housing to open and close the internal space of the valve housing. The elastic member is inserted into the lower part of the valve housing to elastically support the valve member upward. The valve stem is inserted into the upper part of the valve housing to pressurize the valve member downward.

[0019] A seat may be further configured in the pressure reducing valve. The seat may cover the lower opening of the valve housing. An inlet hole may be formed in the seat through which hydrogen introduced from the hydrogen inlet into the hydrogen flow path flows. The upper end of the elastic member may be inserted and positioned into the internal space of the valve member through the lower opening of the valve member. The lower end of the elastic member may be supported by the seat.

[0020] A first outlet hole may be formed on the outer surface of the valve member to discharge hydrogen from the internal space of the valve member into the internal space of the valve housing. A second outlet hole may be formed on the outer surface of the valve housing to discharge hydrogen from the internal space of the valve housing into the hydrogen flow path when the valve member opens the internal space of the valve housing.

[0021] The upper portion of the valve stem may be positioned to protrude upward from the valve housing.

[0022] A solenoid valve may be further configured in the hydrogen regulator according to the present invention. The solenoid valve can open and close the flow path between the hydrogen inlet and the pressure reducing valve in the hydrogen flow path.

The outlet path may extend horizontally from the other side of the body to the main path. An outlet port forming the hydrogen outlet may be installed in the outlet path. A piston may be installed at the top of the main path. The solenoid valve may be installed at the bottom of the main path. The pressure reducing valve may be installed below the piston in the main path. The pressure reducing valve may be opened or closed based on the difference between the pressure applied downward by the piston and the pressure of the hydrogen flowing into the path between the hydrogen outlet and the pressure reducing valve in the main path.

[0024] An outlet pressure relief channel may be further configured in the hydrogen flow path. The outlet pressure relief channel may extend vertically from the bottom of the body to the outlet channel. The outlet pressure relief channel may be arranged parallel to the main channel. An outlet pressure relief valve may be installed in the outlet pressure relief channel. The outlet pressure relief valve may discharge the hydrogen introduced into the outlet channel when the pressure of the hydrogen introduced into the outlet channel exceeds a predetermined pressure upon opening of the pressure reducing valve.

[0025] A first elastic member may be disposed on the upper side of the piston. The first elastic member may provide elastic force for the vertical movement of the piston. A second elastic member may be disposed within the solenoid valve. The second elastic member may provide elastic force for the opening and closing operation of the solenoid valve. A third elastic member may be disposed within the outlet pressure release valve. The third elastic member may provide elastic force for the opening and closing operation of the outlet pressure release valve. A fourth elastic member may be disposed within the pressure reducing valve. The fourth elastic member may provide elastic force for the opening and closing operation of the pressure reducing valve. The first elastic member, the second elastic member, the third elastic member, and the fourth elastic member may provide elastic force in the vertical direction.

[0026] An inlet pressure release path may be further configured in the hydrogen flow path. The inlet pressure release path may extend horizontally from the outer surface of the body to the main path between the hydrogen inlet and the pressure reducing valve. The inlet pressure release path may be arranged perpendicular to the main path and the inlet path. An inlet pressure release valve may be installed in the inlet pressure release path. When the solenoid valve is opened, the inlet pressure release valve may discharge the hydrogen flowing into the main path between the hydrogen inlet and the pressure reducing valve if the pressure of the hydrogen flowing into the main path between the hydrogen inlet and the pressure reducing valve is above a predetermined pressure.

[0027] A sensor path may be further configured in the hydrogen flow path. The sensor path may extend horizontally from the outer surface of the body to the main path between the hydrogen outlet and the pressure reducing valve. The sensor path may be arranged orthogonally to the main path and the outlet path. A pressure sensor may be installed in the sensor path. The pressure sensor may detect the pressure in the main path between the hydrogen outlet and the pressure reducing valve.

[0126] The operation of the hydrogen regulator (1) according to the embodiment of the present invention configured as above is described as follows.

[0127] When the solenoid valve (500) closes the path between the hydrogen inlet (301) and the pressure reducing valve (700) in the main path (110) of the hydrogen flow path of the body (100), hydrogen may not be supplied from the hydrogen inlet (301) to the pressure reducing valve (700).

[0128] When the solenoid valve (500) opens the path between the hydrogen inlet (301) and the pressure reducing valve (700) in the main path (110) of the hydrogen flow path of the body (100), hydrogen can be supplied from the hydrogen inlet (301) to the pressure reducing valve (700).

[0129] The operation of the hydrogen regulator (1) when the solenoid valve (500) opens the path between the hydrogen inlet (301) and the pressure reducing valve (700) in the main path (110) of the hydrogen flow path of the body (100) is as follows.

[0130] With the solenoid valve (500) opening the path between the hydrogen inlet (301) and the pressure reducing valve (700) in the main path (110) of the hydrogen flow path of the body (100), hydrogen flowing into the hydrogen inlet (301) passes through the path between the hydrogen inlet (301) and the pressure reducing valve (700) in the main path (110), flows into the interior of the valve housing (710) through the inlet hole (752) of the seat (750) of the pressure reducing valve (700), and then flows into the interior space of the valve member (720).

[0131] At this time, if the pressure of hydrogen at the hydrogen outlet (401) side is less than the elastic force of the first elastic member (230), the piston (220) moves downward by the elastic force of the first elastic member (230), and accordingly, the valve stem (740) moves downward, causing the valve member (720) to move downward and the internal space of the valve housing (710) to open.

[0132] Accordingly, hydrogen introduced into the internal space of the valve member (720) of the pressure reducing valve (700) can be discharged to the internal space of the valve housing (710) through the first outlet hole (722) of the valve member (720), then discharged to the main flow path (110) located outside the valve housing (710) through the second outlet hole (712) of the valve housing (710), and then discharged to the hydrogen outlet (401) by passing through the outlet flow path (130).

[0133] Subsequently, when the pressure of hydrogen on the hydrogen outlet (401) side becomes greater than the elastic force of the first elastic member (230), the piston (220) moves upward due to the pressure of hydrogen on the hydrogen outlet (401) side, and accordingly, the valve member (720) moves upward due to the pressure of hydrogen on the hydrogen inlet (301) side, thereby moving the valve stem (740) upward and closing the internal space of the valve housing (710).

[0134] As described above, in the hydrogen regulator (1) according to the embodiment of the present invention, since the valve stem (740) for operating the pressure reducing valve (700) is arranged to be movable up and down within the pressure reducing valve (700), the operation of the pressure reducing valve (700) can be smooth even when used for a long time.

[0135] In addition, in the hydrogen regulator (1) according to the embodiment of the present invention, since the parts constituting the pressure reducing valve (700) are installed within the valve housing (710) and the pressure reducing valve (700) is provided as a single assembly, it is easy to install the pressure reducing valve (700) within the body (100).

[0136] In addition, the hydrogen regulator (1) according to an embodiment of the present invention includes a pressure reducing valve (700) operated by the pressure of hydrogen and an electronically operated solenoid valve (500) to open and close the hydrogen flow path extending from the hydrogen inlet (301) to the hydrogen outlet (401), so that the pressure of the hydrogen introduced into the hydrogen flow path can be easily controlled.

[0137] A person skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
