Description

Technical Field

[0001] This utility model belongs to the field of one-way valve technology and relates to a one-way valve throttling structure. Background Technology

[0002] The main drawbacks of existing check valves in terms of flow stabilization, sealing, and throttling lie in their design and operating principle. Check valves typically rely on spring force to keep the valve disc closed, preventing backflow of the medium. However, this design can lead to incomplete sealing under stable flow conditions because the spring force may not be sufficient to completely overcome hydrodynamic and pressure fluctuations, especially in high-pressure or high-flow-rate systems. The root cause of these drawbacks lies in the fact that the mechanical structure and operating principle of check valves limit their precise control over fluid dynamics. Conventional methods to address these shortcomings include increasing the spring force, using a more sophisticated valve disc design, or employing auxiliary devices to stabilize the flow. However, these methods also have drawbacks. Increasing the spring force may require greater pressure to open the valve disc, thus increasing system energy consumption and wear. While a more sophisticated valve disc design can improve sealing performance, it increases manufacturing costs and complexity. Therefore, there is an urgent need for a check valve throttling structure to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a one-way valve throttling structure to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a one-way valve throttling structure, including: a side liquid guide end and a valve cavity, wherein a set of valve bodies for allowing liquid to flow through is provided on the right side of the side liquid guide end, a set of valve cavities for allowing liquid to flow in one direction is provided inside the valve bodies, and a set of core seats for unidirectional diversion of liquid introduced into the inlet end is provided inside the valve cavity.

[0005] The bottom of the core seat is connected and fixed to the lower end of the valve body by a set of fixing bolts. The lower end of the core seat is a fixed structure. The core seat includes a pressure bearing head and a spring. The pressure bearing head is located inside the lower end of the liquid inlet chamber. The lower end of the pressure bearing head is provided with a set of sealing ring seats for sealing and fitting between the valve chamber and the liquid inlet chamber. The sealing ring seats are located at the middle position of the top of the valve chamber.

[0006] In a preferred embodiment, the pressure head has a set of guide grooves on its left and right sides for uniformly distributing external liquid. The lower end of the sealing ring seat has a set of internal damping cores for compression with the upper end of the fixed seat. In actual use, when liquid enters the inlet chamber from the inlet end, the pressure acts on the pressure head, causing it to move upward against the spring force. The guide grooves uniformly distribute the liquid to the valve chamber. At this time, the sealing ring seat separates from the inner wall of the valve chamber to form a passage. The liquid flows out from the side guide end of the valve chamber. When flowing in the opposite direction, the liquid pressure pushes the sealing ring seat to fit tightly against the top of the valve chamber to achieve a seal. The internal damping core buffers the pressure impact through the compression stroke. The throttling function achieves flow regulation through the cross-sectional change of the guide groove. The fixing bolt ensures the rigid connection between the core seat and the valve body. Under high pressure conditions, the cooperation between the internal damping core and the fixed seat can stabilize the valve core movement and prevent sealing failure caused by vibration. The entire structure achieves unidirectional shut-off through the dynamic cooperation between the sealing ring seat and the valve chamber, and at the same time, it uses the guide grooves and internal damping cores to achieve flow control and pressure buffering.

[0007] In a preferred embodiment, the inner damping core and the sealing ring seat are an integral structure. The inner damping core is sealed and limited at the upper end of the fixed seat. The front cross-section of the fixed seat is a convex structure. The bottom of the fixed seat is provided with a set of support plates. A set of springs for reverse support of the sealing ring seat is provided between the support plates and the sealing ring seat.

[0008] In a preferred embodiment, the support plate has a set of internal threaded holes in the middle position for connection by a fixing bolt, and the internal threaded holes have the same structure as the fixing bolt through position inside the valve body.

[0009] In a preferred embodiment, the upper end of the valve body is provided with a set of inlet ends for introducing external liquid into the valve body, and the inlet ends are provided with a set of inlet chambers for introducing external liquid.

[0010] In a preferred embodiment, the valve body has a set of two side guide liquid terminals on the right side for guiding liquid into the flow. The two side guide liquid terminals are of the same specification and are respectively sealed to a set of external liquid distribution pipes. The interiors of both the first and second side guide liquid terminals are interconnected with the interior of the valve body. After the liquid enters the inlet chamber from the inlet terminal, pressure acts on the pressure head, causing it to move the integrated internal damping core and the sealing ring assembly upwards. The guide groove evenly distributes the liquid into the valve cavity. At this time, the sealing ring detaches from the top of the valve cavity, forming a passage, allowing the liquid to flow through the valve cavity from the side guide liquid terminal. Liquid flows out from either end one or side guide end two. When flowing in the opposite direction, the liquid pressure pushes the sealing ring seat to reset and achieve a seal. The convex structure of the fixed seat forms a limiting fit with the inner damping core. The support plate ensures structural stability through fixing bolts. The dual liquid guide end design allows for bidirectional liquid diversion. It can be connected to external pipelines through standard interfaces. The throttling function achieves flow regulation through changes in the cross-section of the guide groove. The inner damping core generates a buffering effect during movement. The entire working process achieves unidirectional cutoff through the dynamic opening and closing of the sealing ring seat, while the guide groove is used to achieve diversion control. The fixed seat assembly provides stable support and limiting functions.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the liquid enters the inlet chamber from the inlet end, the pressure acts on the pressure bearing head to make it move upward against the spring force. The guide groove distributes the liquid evenly to the valve chamber. At this time, the sealing ring seat separates from the inner wall of the valve chamber to form a passage. The liquid flows out from the side guide end through the valve chamber. When flowing in the reverse direction, the liquid pressure pushes the sealing ring seat to fit tightly with the top of the valve chamber to achieve a seal. The inner damping core buffers the pressure impact through the compression stroke. The throttling function achieves flow regulation through the cross-sectional change of the guide groove. The fixing bolt ensures the rigid connection between the core seat and the valve body. Under high pressure conditions, the cooperation between the inner damping core and the fixing seat can stabilize the valve core movement and prevent the sealing failure caused by vibration. The entire structure achieves unidirectional shut-off through the dynamic cooperation between the sealing ring seat and the valve chamber. At the same time, the guide groove and the inner damping core are used to achieve flow control and pressure buffering.

[0012] After the liquid enters the inlet chamber from the inlet end, the pressure acts on the pressure head, causing it to move the integrated internal damping core and the sealing ring assembly upwards. The guide channel evenly distributes the liquid to the valve chamber. At this time, the sealing ring detaches from the top of the valve chamber to form a passage. The liquid can flow out of the valve chamber from either the first or second side guide end. When flowing in the opposite direction, the liquid pressure pushes the sealing ring to reset and achieve a seal. The convex structure of the fixed seat forms a limiting fit with the internal damping core. The support plate ensures structural stability through the fixing bolts. The dual guide end design allows for bidirectional liquid diversion. It can be connected to external pipelines through standard interfaces. The throttling function achieves flow regulation through the change of the cross-section of the guide channel. The internal damping core generates a buffering effect during movement. The entire working process achieves unidirectional cutoff through the dynamic opening and closing of the sealing ring, while the guide channel achieves diversion control. The fixed seat assembly provides stable support and limiting functions. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 As the first embodiment of this utility model:

The right side of the side liquid guide end 100 is provided with a set of valve bodies 120 for passing liquid through. The valve body 120 is provided with a set of valve cavities 170 for one-way flow of liquid. The valve cavity 170 is provided with a set of core seats 160 for one-way diversion of liquid introduced into the inlet end 140.

[0022] The bottom of the core seat 160 is connected and fixed to the lower end of the valve body 120 by a set of fixing bolts 130. The lower end of the core seat 160 is a fixed structure. The core seat 160 includes a pressure bearing head 16a, a sealing ring seat 16c and a spring 16f. The pressure bearing head 16a is located inside the lower end of the liquid inlet chamber 150. The lower end of the pressure bearing head 16a is provided with a set of sealing ring seats 16c for sealing and fitting between the valve chamber 170 and the liquid inlet chamber 150. The sealing ring seat 16c is located at the middle position of the top of the valve chamber 170.

[0023] The pressure head 16a has a set of guide grooves 16b on both sides for evenly distributing the external liquid. The lower end of the sealing ring seat 16c has an internal damping core 16d for compression against the upper end of the fixed seat 16e. In actual use, when liquid enters the inlet chamber 150 from the inlet end 140, pressure acts on the pressure head 16a, causing it to overcome the force of the spring 16f and move upwards. The guide grooves 16b evenly distribute the liquid to the valve chamber 170. At this time, the sealing ring seat 16c separates from the inner wall of the valve chamber 170, forming a passage. The liquid flows out from the side guide end 100 through the valve chamber 170. When flowing in the reverse direction, the liquid pressure... The sealing ring seat 16c is pushed to fit tightly against the top of the valve cavity 170 to achieve a seal. The inner damping core 16d buffers pressure impact through compression stroke. The throttling function achieves flow regulation through the cross-sectional change of the guide groove 16b. The fixing bolt 130 ensures the rigid connection between the core seat 160 and the valve body 120. Under high pressure conditions, the cooperation between the inner damping core 16d and the fixing seat 16e can stabilize the valve core movement and prevent sealing failure caused by vibration. The entire structure achieves unidirectional shut-off through the dynamic cooperation between the sealing ring seat 16c and the valve cavity 170, while using the guide groove 16b and the inner damping core 16d to achieve flow control and pressure buffering.

[0024] Please see Figures 1-3 As a second embodiment of this utility model: based on the description in the above embodiments, further,

[0025] The inner damping core 16d and the sealing ring seat 16c are an integral structure. The inner damping core 16d is sealed and limited at the upper end of the fixed seat 16e. The front cross-section of the fixed seat 16e is a convex structure. The bottom of the fixed seat 16e is provided with a set of support plates. Between the support plates and the sealing ring seat 16c, there is a set of springs 16f for reverse support of the sealing ring seat 16c.

[0026] The support plate has a set of internal threaded holes in the middle position for connection by the fixing bolt 130. The internal threaded holes have the same structure as the fixing bolt 130 through the valve body 120.

[0027] The upper end of the valve body 120 is provided with a set of inlet end 140 for introducing external liquid into the valve body 120, and the inlet end 140 is provided with a set of inlet chamber 150 for introducing external liquid.

[0028] The valve body 120 has a set of side guide ends 110 on the right side for guiding the liquid on the right side. Side guide ends 100 and 110 are of the same specifications. Their outer sides are respectively sealed to a set of external liquid diversion pipes. The interiors of side guide ends 100 and 110 are interconnected with the interior of the valve body 120. The working process of this one-way valve and throttling structure is as follows: After the liquid enters the inlet chamber 150 from the inlet end 140, the pressure acts on the pressure head 16a, causing it to move the integrated internal damping core 16d and the sealing ring seat 16c assembly upward. The guide groove 16b evenly distributes the liquid to the valve chamber 170. At this time, the sealing ring seat 16c disengages from the top of the valve chamber 170 to form a passage, and the liquid can pass through... The valve chamber 170 flows out from either the first side liquid guide end 100 or the second side liquid guide end 110. When flowing in the opposite direction, the liquid pressure pushes the sealing ring seat 16c to reset and achieve sealing. The convex structure of the fixed seat 16e forms a limiting fit with the inner damping core 16d. The support plate ensures structural stability through the fixing bolt 130. The dual liquid guide end design allows for bidirectional liquid diversion. It can be connected to external pipelines through a standard interface. The throttling function achieves flow regulation through the cross-sectional change of the guide groove 16b. The inner damping core 16d generates a buffering effect during movement. The entire working process achieves unidirectional cutoff through the dynamic opening and closing of the sealing ring seat 16c. At the same time, the guide groove 16b is used to achieve diversion control. The fixed seat 16e assembly provides stable support and limiting functions.
