Description

Technical Field

[0001] The utility model relates to the technical field of pistons, in particular to a one-way piston. Background Art

[0002] A one-way piston typically refers to a mechanism in which a piston is subjected to force or moves in only one direction. In a one-way piston mechanism, pressure or force is applied to one side of the piston, pushing it in one direction. When the pressure or force is removed, the piston returns to its original position, perhaps using a spring or other return mechanism.

[0003] Due to the complex design of the one-way passage of a one-way piston, which consists of two semi-cylinders or rectangular blocks that snap together to form a complete one-way piston, a gap can easily form at the joint, compromising the piston's effectiveness. This gap can compromise the piston's seal, allowing fluid (such as gas or liquid) to leak between the two sides. This leakage reduces piston efficiency and can even degrade the performance of the entire system. The gap creates turbulence and eddies as the fluid passes through it, which in turn increases wear between the piston and cylinder wall. Over time, wear can cause the piston's size and shape to change, further compromising its sealing performance and motion stability. Furthermore, wear can generate impurities such as metal debris, which can enter other parts of the system and cause further damage. Utility Model Content

[0004] The purpose of the present utility model is to provide a one-way piston to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A piston body 1 and a piston body 2, wherein the piston body 1 and the piston body 2 are engaged with each other, and a one-way channel is opened in the middle of the piston body 1 and the piston body 2;

[0008] A clamping assembly, which is respectively provided on the first piston body and the second piston body, and is used to fix the first piston body and the second piston body;

[0009] A sealing component is provided on the piston body 1 and the piston body 2, and the sealing component seals the gap between the piston body 1 and the piston body 2 when the clamping component is fixed.

[0010] Preferably, the one-way channels provided on the piston body 1 and the piston body 2 are groove 1 and groove 2, and the groove 1 and groove 2 are respectively provided on the piston body 1 and the piston body 2, and the one-way channel is formed by the piston body 1 and the piston body 2 being buckled together.

[0011] Preferably, sleeves are provided on the outer surfaces of the piston body 1 and the piston body 2, and the inner walls of the sleeves are in contact with the piston body 1 and the piston body 2.

[0012] Preferably, the sleeve is provided with a gasification chamber below the piston body 1 and the piston body 2, and the sleeve is provided with a compression chamber below the piston body 1 and the piston body 2. The upper end and the lower end of the outer surface of the sleeve are connected to the gasification chamber and the compression chamber via pipeline 1 and pipeline 2 respectively.

[0013] Preferably, the clamping assembly includes a clamping groove, which is symmetrically arranged on the four corners of the piston body, and the bottom of the clamping groove is arranged to have a structure with a gradually increasing inner diameter.

[0014] Preferably, the clamping assembly further includes a clamping block, the clamping block is provided with a protrusion, and the clamping block is fixedly arranged on the second piston body.

[0015] Preferably, the clamping block is engaged and adapted with the bottom of the clamping slot via a protrusion.

[0016] Preferably, the sealing assembly includes an extrusion strip, and the extrusion strip is fixedly mounted on the second piston body.

[0017] Preferably, the sealing assembly further comprises an installation groove, and the installation groove is arranged along the four sides of the horizontal plane of the piston body.

[0018] Preferably, a sealing gasket is fixedly connected in the installation groove, one side of the sealing gasket is set as an inclined surface, and the size of the sealing gasket is adapted to the size of the extrusion strip.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By setting the one-way channel as a combination of multiple arc grooves, backflow is avoided. The arc reflux design can effectively prevent the fluid from flowing back in the one-way channel by guiding the fluid to flow along a specific path.

[0021] The block is inserted into the slot, where its protrusions engage and adapt to the bottom of the slot. The slots are symmetrically positioned at the four corners of the piston body. This design not only enhances the stability of the piston body but also provides precise positioning and support for the block's installation. The slot's bottom features a gradually increasing inner diameter, allowing the block to gradually adapt and closely conform to the slot's shape during insertion, thereby enhancing the stability and reliability of the engagement.

[0022] When the first and second piston bodies are fastened together, the clamping block engages the slot, prompting the extrusion strip to squeeze the sealing gasket. When the first and second piston bodies are fully fastened together, the extrusion strip compresses the sealing gasket until it completely fits against the inner walls of the first and second piston bodies. The extrusion strip forces the sealing gasket to tightly adhere to the inner walls of the first and second piston bodies, forming an effective sealing barrier. This tight fit helps prevent fluid from leaking through the gap in the piston, thereby improving the system's sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is described in further detail below with reference to the accompanying drawings.

[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0032] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0033] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example

[0034] See also Figure 1-Figure 5 A one-way piston includes a piston body 1 and a piston body 2. The piston body 1 and the piston body 2 are configured as semi-cylindrical bodies. The piston body 1 and the piston body 2 are interlocked. A one-way channel is opened in the middle of the piston body 1 and the piston body 2. The one-way channel is configured as a combination of multiple arc grooves to prevent backflow. The arc reflux design can effectively prevent backflow of the fluid in the one-way channel by guiding the fluid to flow along a specific path. This is particularly important for systems that require strict control of fluid flow direction.

[0035] A one-way piston also includes: a clamping assembly, which is respectively arranged on the piston body 1 and the piston body 2, 2, and is used to fix the piston body 1 and the piston body 2, and the clamping assembly can firmly connect the piston body 1 and the piston body 2 together to form an integral structure. This fixed connection can significantly improve the structural stability of the piston and prevent the piston from disintegrating or being damaged due to uneven force or vibration during use. In a high-pressure environment, the piston needs to withstand greater pressure. The transverse fixed connection of the clamping assembly can enhance the piston's pressure resistance, ensure that it can still maintain a stable working state under high pressure, and avoid the separation of the piston body 1 and the piston body 2 when the one-way piston moves longitudinally;

[0036] A one-way piston also includes a sealing assembly, which is mounted on piston body 1 and piston body 2. When the clamping assembly is secured, the sealing assembly seals the gap between piston body 1 and piston body 2. The sealing assembly tightly fills the gap between piston body 1 and piston body 2, effectively preventing fluid (gas or liquid) from leaking through the gap. Reduced leakage means more stable system operation, avoiding problems such as pressure fluctuations and flow rate variations caused by leakage. This helps maintain system stability and reliability.

[0037] The one-way passages within piston bodies 1 and 2 are grooves 1 and 2, respectively, located on piston bodies 1 and 2. These grooves 1 and 2 form a one-way passage when they interlock, ensuring a continuous, smooth one-way passage. This passage ensures orderly fluid flow within the piston, preventing problems such as backflow or leakage. By precisely controlling the direction of fluid flow, one-way pistons can play a key role in various systems.

[0038] It should be noted that the outer surfaces of piston bodies 1 and 2 are provided with sleeves 5. The inner walls of sleeves 5 are in contact with piston bodies 1 and 2, ensuring smooth flow of fluid within the piston. Sleeves 5 are located below piston bodies 1 and 2, and contain a vaporization chamber 6. This chamber is used to store and supply vaporized fluids (such as steam, gas, etc.). These fluids can enter sleeves 5 through pipes 1 and 8, further participating in the system's fluid control process. Sleeves 5 are located between piston bodies 1 and 2, and contain compression chambers 7. This chamber is used to compress and store fluids so that high-pressure fluids can be delivered to sleeves 5 or other parts of the system via pipes 2 and 9 when needed. The upper and lower ends of sleeves 5's outer surface are connected to vaporization chambers 6 and compression chambers 7, respectively, via pipes 1 and 8 and 2 and 9.

[0039] Furthermore, the clamping assembly includes a clamping slot 10, which is symmetrically arranged on the four corners of the piston body 1, and the bottom of the clamping slot 10 is configured as a structure with a gradually increasing inner diameter. The clamping assembly also includes a clamping block 11, which is provided with a protrusion, and the clamping block 11 is fixedly arranged on the piston body 2. The clamping block 11 is mutually clamped and adapted with the bottom of the clamping slot 10 through the protrusion. The clamping slot 10 is symmetrically arranged on the four corners of the piston body 1. This design not only enhances the stability of the piston body 1, but also provides precise positioning and support for the installation of the clamping block 11. The bottom of the clamping slot 10 is configured as a structure with a gradually increasing inner diameter. This design enables the clamping block 11 to gradually adapt to and fit tightly to the shape of the clamping slot 10 when inserted into the clamping slot 10, thereby enhancing the stability and reliability of the clamping.

[0040] Furthermore, the sealing assembly includes an extrusion strip 12, which is fixedly mounted on the piston body 2. The sealing assembly also includes a mounting groove 13, which is arranged along the four sides of the horizontal surface of the piston body 1. A sealing gasket 14 is fixedly connected to the mounting groove 13, and one side of the sealing gasket 14 is arranged as an inclined surface. The size of the sealing gasket 14 is adapted to the size of the extrusion strip 12. When the piston body 1 and the piston body 2 are fastened together, the clamping block 11 is clamped into the clamping groove 10, prompting the extrusion strip 12 to squeeze the sealing gasket 14. When the piston body 1 and the piston body 2 are fully fastened together, the extrusion strip 12 squeezes the sealing gasket 14 to completely fit the inner walls of the piston body 1 and the piston body 2. Under the action of the extrusion strip 12, the sealing gasket 14 tightly fits the inner walls of the piston body 1 and the piston body 2, forming an effective sealing barrier. This tight fit helps prevent the fluid from leaking out of the gap in the piston, thereby improving the sealing performance of the system.
