Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, and in particular to a vertical one-way valve with power generation function. Background Technology

[0002] Energy and environmental issues are becoming increasingly serious as a matter of great concern today. With economic development, non-renewable energy sources such as coal, oil, and natural gas are dwindling, and their pollution problems are worsening, necessitating the discovery of multiple ways to obtain clean electricity. Currently, electricity is typically obtained through generators and similar equipment, but the application scenarios for generators are severely limited, thus hindering energy conservation and emission reduction efforts.

[0003] Furthermore, in the field of process equipment, equipment is becoming increasingly sophisticated and intelligent, necessitating the installation of numerous sensors and instruments. For instance, in oil refining plants, an increasing number of devices require monitoring and instrumentation to improve control performance and accomplish complex production tasks. However, each additional monitoring point necessitates addressing the power supply issue. Due to safety requirements, oil refining plants cannot lay extensive electrical wiring, leaving many locations without sufficient power to install monitoring and instrumentation. Therefore, new power generation methods are needed to convert some of the kinetic energy of the normally flowing liquid in pipelines into electrical energy, thereby powering the monitoring and instrumentation equipment.

[0004] Chinese patent CN201310341448.5, "Electromagnetic Hydraulic Engine for Internal Combustion Engine," works by converting the thermal energy of an internal combustion engine into electromagnetic and hydraulic energy. Specifically, it integrates the piston of the internal combustion engine with the permanent magnet mover of a reciprocating linear magneto and the plunger shaft of a reciprocating plunger oil pump, thereby generating electricity through the reciprocating motion of the piston.

[0005] Chinese patent CNCN201410175416.7, "Internal Combustion Electromagnetic Air Engine," coaxially connects the internal combustion piston, the compressor piston, and the linear motor's mover. These components are fitted together with the internal combustion cylinder, the compressor cylinder, and the linear stator, and can slide up and down. The internal combustion piston operates in two strokes: the expansion of the internal combustion piston drives the coaxially connected compressor piston and linear mover to move downwards synchronously to perform work. After the downward movement is completed, the linear motor causes the internal combustion piston and compressor piston to move upwards synchronously. Through the alternating up and down reciprocating motion of the linear mover and the internal combustion piston, the four processes of intake, compression, combustion, and exhaust of the internal combustion engine are completed, enabling the compressed air output by the compressor to serve as a power source for external pneumatic machinery or vehicles.

[0006] The above patents relate to electromagnetic power generation, but they do not address the current problem that electricity is generally obtained through generators and other equipment, which greatly limits the application scenarios of generators and hinders energy conservation and emission reduction efforts. They also do not solve the problem that oil refining enterprises, due to safety requirements, cannot lay a large number of electrical wires, resulting in many locations being unable to install monitoring and instrumentation equipment due to a lack of power supply. Therefore, it is necessary to find new power generation methods to convert part of the kinetic energy of normally flowing liquids in pipelines into electrical energy, thereby providing power to monitoring and instrumentation equipment. Furthermore, in fluid control, check valves are commonly used components in fluid pipelines, but current technologies primarily use them for directional control of liquids; no method has been found to use check valves as a power generation tool. Summary of the Invention

[0007] To address the shortcomings of the existing technologies, this invention provides a vertical check valve with power generation function. This valve solves the technical problem that the current method of obtaining electricity generally relies on generators and other equipment, which greatly limits the application scenarios of generators and hinders energy conservation and emission reduction efforts. It also solves the technical problem that oil refining enterprises, due to safety requirements, cannot install a large number of electrical wires, resulting in many locations lacking power supply and thus preventing the installation of monitoring and instrumentation equipment. Therefore, a new power generation method is needed to convert some of the kinetic energy of the normally flowing liquid in the pipeline into electrical energy, thereby providing power to monitoring and instrumentation equipment.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A vertical check valve with power generation function includes:

[0010] A valve body, wherein a cavity is formed inside the valve body;

[0011] A permanent magnet, capable of high-frequency up-and-down movement, is disposed inside the cavity;

[0012] A coil is arranged on the outer wall of the valve body;

[0013] A shock-absorbing and sealing mechanism is installed at the bottom of the valve body.

[0014] In some embodiments, the permanent magnet is further provided with through holes through which fluid can pass.

[0015] In some embodiments, the permanent magnet is encased in a protective shell, which is spherical.

[0016] In some embodiments, the number of turns of the coil is set to n, where n > 1.

[0017] In some embodiments, the valve body has a first flange at the top and a second flange at the bottom.

[0018] In some embodiments, the first flange is further provided with a retaining ring to prevent the permanent magnet from being ejected from the cavity.

[0019] In some embodiments, the shock-absorbing sealing mechanism further includes:

[0020] A valve core is disposed within the cavity, and the valve core is positioned opposite to the permanent magnet.

[0021] A bracket, the edge of which is fixed to the inlet of the valve body, and a through hole is formed in the center of the bracket;

[0022] A valve stem passes through the through hole of the bracket, and the upper end of the valve stem is connected to the center of the circular surface of the valve core.

[0023] In some embodiments, the lower end of the valve stem is further connected to a stop block, the diameter of which is larger than the diameter of the through hole on the bracket.

[0024] In some embodiments, a spring that can freely extend and compress in the vertical direction is installed between the valve core and the bracket, and the spring is sleeved on the valve stem.

[0025] In some embodiments, the valve core further includes a seal.

[0026] In some embodiments, the valve core further includes a raised ridge that attaches a seal to the conical surface of the valve core.

[0027] In some embodiments, the top of the valve core is concave.

[0028] In some embodiments, the vertical check valve with power generation function further includes an electromagnet assembly or a permanent magnet ring.

[0029] In some embodiments, the electromagnet assembly is controlled by an electromagnet controller, and the electromagnet assembly and the electromagnet controller are connected by an electromagnet control circuit.

[0030] In some embodiments, the electromagnet assembly includes a plurality of electromagnets disposed on the valve body; the number of the electromagnets matches the number of the electromagnet control circuits.

[0031] In some embodiments, the permanent magnet ring is disposed on the valve body, and its position on the valve body can be adjusted up and down by means of threads or guide rods.

[0032] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0033] 1. The vertical check valve with power generation function provided by this invention can be installed in any pipeline, converting part of the kinetic energy of the fluid in the pipeline into electrical energy. The retaining ring on the valve body converts the fluid kinetic energy that cannot be used under normal circumstances into electrical energy, which plays a role in energy saving and emission reduction. The valve body structure provides power to parts of the field device where it is impossible to run wires, making it possible to install testing and instrumentation equipment. The vertical check valve technology with power generation function provided by this invention can also be applied to cutting-edge technology fields such as spacecraft, making it easy to convert fluid momentum into electrical energy in a limited space, and its application space is huge.

[0034] 2. The vertical one-way valve with power generation function provided by the present invention has a large manufacturing size. It has a shock-absorbing sealing mechanism at the bottom of the valve body, which can realize the opening and closing of the valve without making the permanent magnet in the cavity of the valve body very large. In addition, the spring in the shock-absorbing sealing mechanism significantly reduces the impact force generated when the permanent magnet falls. At the same time, the protective shell of the permanent magnet is spherical, so the kinetic energy loss is small when the fluid passes through the protective shell. Attached Figure Description

[0041] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of the present invention, but it is not intended to limit the scope of protection of the appended claims.

[0042] Certain terms are used in this specification and the following claims to refer to specific components or parts. Those skilled in the art will understand that users or manufacturers may use different names or terms to refer to the same component or part. This specification and the following claims do not distinguish components or parts by differences in name, but rather by differences in function. The terms "comprising" and "including" used throughout this specification and the following claims are open-ended and should be interpreted as "including but not limited to". Furthermore, the term "connection" here includes any direct and indirect electrical connection means. Indirect electrical connection means include connections made through other means.

[0043] It should be noted that in the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and "about", or "approximately", "substantially", "left and right", etc., indicating the orientation or positional relationship or parameters, are all based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, a specific size, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0044] like Figure 1 This is a schematic diagram of a solenoid valve that does not have a one-way valve function but can generate electricity, provided in an embodiment of the present invention. If the sealing requirements are not very high, this solenoid valve can be used. This solenoid valve contains fewer components, including: a valve body 1, the valve body 1 having a cavity 101 formed inside; a permanent magnet 4, which is disposed inside the cavity 101 and can move up and down at high frequency; and a coil 3, which is arranged on the outer wall of the valve body 1; thus realizing the power generation function.

[0045] However, to ensure even better performance, another embodiment of the present invention provides, as follows: Figure 2 The vertical check valve with power generation function shown includes:

[0046] A valve body 1, wherein a cavity 101 is formed inside the valve body 1; the valve body 1 is made of a non-ferrous metal material, preferably a polymer material or an aluminum alloy material.

[0047] A permanent magnet 4, capable of high-frequency up-and-down movement, is disposed inside the cavity 101;

[0048] A coil 3 is arranged on the outer wall of the valve body 1;

[0049] A shock-absorbing and sealing mechanism is installed at the bottom of the valve body 1.

[0050] The permanent magnet 4 is further provided with a through hole 401 through which fluid can pass. The permanent magnet 4 is encased in a protective shell 402, which is spherical. Because of its spherical shape, the fluid experiences less kinetic energy loss when flowing through the protective shell 402. The permanent magnet 4 is made of a strong magnet, and the protective shell 402 is made of a soft, permeable polymer material.

[0051] Specifically, the number of turns of the coil 3 is set to n turns, where n > 1, which helps to obtain more electrical energy.

[0052] The valve body 1 has a first flange 102 at its top and a second flange 103 at its bottom. The first flange 102 and the second flange 103 are used to facilitate the vertical installation of the new type of one-way valve with power generation function on the pipeline; of course, the first flange 102 and the second flange 103 can also be omitted in the design and connected to the pipeline by welding.

[0053] Specifically, a retaining ring 2 is further provided at the first flange 102 to prevent the permanent magnet 4 from being pushed out of the cavity 101. In this embodiment, the retaining ring 2 is installed at the first flange 102 and its function is to form a cavity 101 with the valve body 1 to prevent the permanent magnet 4 from being pushed out of the cavity 101 by the fluid and lost.

[0054] The vertical one-way valve with power generation function provided in this embodiment of the invention utilizes fluid impact on permanent magnet 4 to make permanent magnet 4 move up and down at high frequency. The high-frequency up and down movement of permanent magnet 4 will cause the magnetic field to move, which is equivalent to coil 3 cutting magnetic field lines at high frequency, thereby generating current in coil 3. This current is collected and processed, and the generated electrical energy can be stored in a battery through components such as power amplifier and controller to power other related equipment.

[0055] The reason why the permanent magnet 4 can move up and down at high frequency is as follows: When the fluid flows out from the bottom of the pipe, when the contact part between the fluid and the permanent magnet 4 is the non-through hole 401 part, the lifting force generated by the fluid will make the permanent magnet 4 move upward. As the position of the permanent magnet 4 continues to rise, the lifting force of the liquid will gradually decrease. When the lifting force of the liquid is equal to the weight of the permanent magnet 4, the permanent magnet 4 stops moving upward and reaches the highest point. At this time, the permanent magnet 4 is still rotating. When the fluid comes into contact with the through hole 401 part, some of the fluid quickly passes through the through hole 401. At this time, the lifting force generated by the fluid will decrease rapidly, and the permanent magnet 4 will fall rapidly from the highest point. During the falling process, as long as the fluid comes into contact with the non-through hole 401 part again, the lifting force generated by the fluid will increase instantly, making the permanent magnet 4 move upward again. When the fluid impacts the permanent magnet 4, the irregularly changing lifting force generated causes the permanent magnet 4 to move up and down at high frequency.

[0056] In practical applications, some pipelines are very thick, or it is necessary for a solenoid valve with power generation function to function as a check valve. Therefore, the vertical check valve with power generation function provided in this embodiment has a shock-absorbing and sealing mechanism added to the bottom of the valve body 1. This design in this embodiment can achieve valve opening and closing without making the permanent magnet 4 very large. For example, Figure 3 As shown, the shock-absorbing sealing mechanism further includes:

[0057] A valve core 5 is disposed in the cavity 101, and the valve core 5 is disposed opposite to the permanent magnet 4. The valve core 5 is shaped as a frustum.

[0058] A bracket 6, the edge of which is fixed to the inlet of the valve body 1, preferably by welding, and a through hole is formed in the center of the bracket 6;

[0059] A valve stem 7 passes through the through hole of the bracket 6, and the upper end of the valve stem 7 is connected to the center of the circular surface of the valve core 5.

[0060] Specifically, a stop block 701 is further connected to the lower end of the valve stem 7, and the diameter of the stop block 701 is larger than the diameter of the through hole on the bracket 6.

[0061] Specifically, a spring 8, which can freely extend and compress in the vertical direction, is installed between the valve core 5 and the bracket 6. The spring 8 is sleeved on the valve stem 7. The spring provided in this embodiment cannot move left or right, but can freely extend and compress in the vertical direction. The spring 8 is a compression spring. When the permanent magnet 4 leaves the valve core 5, the spring 8 usually lifts the valve core 5, so that the one-way valve is always in the normally open state, and the fluid can flow freely; the fluid here can be gas or liquid.

[0062] The vertical check valve with power generation function provided in this embodiment has a shock-absorbing sealing mechanism installed at the bottom of the valve body 1, which not only allows the size of the check valve to be increased, but also the spring in the shock-absorbing sealing mechanism can significantly reduce the impact force generated when the permanent magnet 4 falls.

[0063] The valve core 5 further includes a sealing element 501, which is preferably made of a polymer material such as rubber. Specifically, the valve core 5 further includes a protruding ridge 502 for attaching the sealing element 501 to the conical surface of the valve core 5. In this embodiment, the protruding ridge 502 is not a necessary structure; its function is to better mount the sealing element 501 onto the conical surface of the valve core 5, and the protruding ridge 502 can be omitted during manufacturing.

[0064] Specifically, the top of the valve core 5 is concave. If the size of the new electromagnetic check valve is made very large, the top of the valve core 5 needs to be made concave so that when the permanent magnet 4 falls on the valve core 5, the permanent magnet 4 can automatically roll to the center position of the valve core 5, thereby preventing the permanent magnet 4 from falling at the edge of the valve core 5 due to its small size, thus preventing the valve core 5 from being biased and the new electromagnetic check valve from closing properly.

[0065] The vertical one-way valve with power generation function further includes an electromagnet assembly 9 or a permanent magnet ring 12.

[0066] Specifically, the electromagnet assembly 9 is controlled by an electromagnet controller 10, and the electromagnet assembly 9 and the electromagnet controller 10 are connected by an electromagnet control circuit 11.

[0067] The electromagnet assembly 9 includes multiple electromagnets mounted on the valve body 1; the number of electromagnets matches the number of electromagnet control circuits. In the design, the permanent magnet 4 can move up and down at high frequency, and sometimes it is necessary to adjust the magnitude of each force. Therefore, the electromagnet assembly 9 is installed on the upper part of the outer wall of the cavity 101 of the valve body 1. The electromagnet assembly 9 has multiple sets of electromagnets, which are connected to the controller 10 via control circuits 11. The controller 10 controls the energization or de-energization of each set of electromagnets in the electromagnet assembly 9, thereby controlling the magnitude of the electromagnet's attractive force; it can also change the direction of the current, changing the polarity of the electromagnet (for example, changing the original attractive force into a repulsive force), thereby controlling the height that the permanent magnet 4 can reach.

[0068] Specifically, the permanent magnet ring 13 is disposed on the valve body 1, and its position on the valve body 1 can be adjusted up and down via threads or guide rods. For example... Figure 4As shown, considering that the electromagnet assembly 9 cannot be used on site, in another embodiment of the present invention, the electromagnet assembly 9 is replaced with a permanent magnet ring 13. By adjusting the position of the permanent magnet ring 13 on the valve body 1 (which can be adjusted up and down by means of threads, guide rods, etc.), the stroke of the permanent magnet 4 in the cavity 101 can be adjusted, thereby adjusting the magnitude and efficiency of the current generated in the coil 3.

[0069] The vertical check valve with power generation function provided in this invention embodiment can be installed in any pipeline, converting part of the kinetic energy of the fluid in the pipeline into electrical energy. The retaining ring converts the fluid kinetic energy, which is normally unusable, into electrical energy, thus achieving energy conservation and emission reduction. The valve body provides power to parts of the device where it is impossible to run electrical wires, making it possible to install testing and instrumentation equipment. This technology can also be applied to cutting-edge technology fields such as spacecraft, because the application space for easily converting fluid momentum into electrical energy in limited space is enormous. The vertical check valve with power generation function provided in this invention embodiment must be installed vertically; it cannot be installed upside down or horizontally, but a small angle of tilt is acceptable.

[0070] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
