Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a high-pressure valve with an inlet baffle. Background Technology

[0002] A solenoid valve is an electrically controlled valve product. When its internal coil is energized, it can push its valve core to move within the valve body, thereby controlling the valve's on / off state and regulating the flow rate. Furthermore, it can meet the needs of remote control and is widely used in control circuits.

[0003] High-pressure valves in solenoid valves, such as the pressure regulating valve disclosed in patent CN101641514A, typically have a housing. Inside the housing, there is an armature plate and an armature bolt connected to the armature plate. An accessory is also provided inside the housing to limit the stroke of the armature plate. The armature bolt passes through an armature bolt hole in the housing. A compression spring is provided between the armature plate and the accessory. An electromagnetic coil is located inside the housing. A seat ring is provided at the end of the housing, through which an inflow channel passes. A discharge pipe connecting the inflow channel is also provided on the seat ring. The valve element is located within the seat ring at the intersection of the inflow channel and the discharge pipe. The end of the armature bolt away from the armature plate acts on the valve element, i.e., the electromagnetic coil and the compression spring act together on the armature plate. The armature plate drives the armature bolt to move, thereby controlling the movement of the valve element and meeting the requirements for flow control and flow regulation. While the aforementioned structure meets the operational requirements, as a high-pressure valve typically used in high-pressure pipeline environments, its inflow channel is usually a small orifice, and the valve assembly directly acts on this orifice. Meanwhile, the discharge pipelines are usually numerous and have larger orifices, necessitating that the inflow channel be kept undisturbed before installation and use. This means maintaining the inflow channel's cleanliness after manufacturing to prevent impurities from entering and causing blockages before installation. However, the inflow port of existing high-pressure valves is directly exposed, allowing dust and other foreign matter to enter the small orifice during storage and transportation, causing blockages and affecting post-installation performance. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, the present invention aims to provide a high-pressure valve with an inlet baffle. A baffle is installed within the valve seat, and a through hole is formed on the baffle. The baffle is arranged perpendicular to the axial direction of the inflow channel. When the valve is not installed, the baffle seals the port of the inflow channel, effectively preventing impurities and foreign objects from entering the inflow channel during storage and transportation, thus affecting the performance after installation. Furthermore, after installation, the position of the baffle can be changed so that the through hole faces the inflow channel, satisfying the requirement for unobstructed flow after installation.

[0005] The specific technical solution is as follows:

[0006] A high-pressure valve with an inlet baffle includes a housing, a moving iron core assembly, a compression spring, a valve seat, and a valve plug. The housing has a telescopic hole at its center. A coil assembly is coaxially sleeved around the telescopic hole and located inside the housing at one end. The moving iron core assembly includes a moving iron core and a sliding rod. The moving iron core is located at one end of the coil assembly, and a compression spring is located on the side of the moving iron core facing away from the coil assembly. One end of the sliding rod is fixed to the moving iron core, and the other end of the sliding rod passes through the telescopic hole. The valve seat is located at the end of the housing facing away from the coil assembly, and a [missing information - likely a fin] is formed on the valve seat along the axial direction of the sliding rod. The inflow channel has a valve seat on one side wall of the housing with several discharge channels communicating with the inflow channel. One end of the slide rod extends through the telescopic hole to the connection between the inflow channel and the discharge channel. The valve plug is located at the connection between the inflow channel and the discharge channel and selectively contacts the slide rod. It also includes a baffle plate with a through hole. The valve seat has an insertion hole along the radial direction of the inflow channel. The baffle plate is slidably disposed in the insertion hole. When the baffle plate slides in the insertion hole, the through hole is directly opposite to or offset from the inflow channel.

[0007] The aforementioned high-pressure valve with an inlet baffle has a blind port, and a spring is provided between the baffle and the bottom of the port.

[0008] The aforementioned high-pressure valve with an inlet baffle has a spring plate arranged obliquely along the length of the baffle, and the spring plate and the baffle are an integral structure.

[0009] The aforementioned high-pressure valve with an inlet baffle has a protrusion on one side of the baffle. The protrusion is formed by stamping the baffle, and when the baffle is slidably disposed in the insertion hole, the protrusion abuts against the hole wall of the insertion hole.

[0010] The aforementioned high-pressure valve with an inlet baffle has a compression slope at the end of the baffle away from the end where the spring is located, and when the through hole and the inflow channel are offset from each other, the compression slope protrudes to the outside of the insertion hole.

[0011] In the aforementioned high-pressure valve with an inlet baffle, the end of the housing with the valve seat has an embedded hole coaxial with the telescopic hole, the valve seat is embedded in the embedded hole, and a boss is provided at the center of the end face of the valve seat facing the outside of the housing, the inflow channel passes through the boss, and the insertion hole is provided in the boss.

[0012] In the aforementioned high-pressure valve with an inlet baffle, a clearance hole is provided on the boss at the opening of the insertion hole, and the extrusion ramp selectively enters into the clearance hole.

[0013] The aforementioned high-pressure valve with an inlet baffle also includes a sealing groove. Sealing grooves are provided in the inflow channel and on both sides of the insertion hole. Each sealing groove is provided with a sealing ring, and the two sealing rings are respectively attached to the two sides of the baffle.

[0014] The aforementioned high-pressure valve with an inlet baffle has a cover at the end of the housing away from the valve seat, and a movable cavity at the end of the housing with a moving iron core. Both the moving iron core and the compression spring are located in the movable cavity. The cover covers the opening of the movable cavity, and the end of the compression spring away from the moving iron core abuts against the cover.

[0015] In the aforementioned high-pressure valve with an inlet baffle, the valve plug is a steel ball, and a recessed ball cup is provided on the end face of the slide rod near the valve plug.

[0016] The positive effects of the above technical solution are:

[0017] The aforementioned high-pressure valve with an inlet baffle has a socket hole radially formed on the valve seat, which has an inflow channel and a discharge channel. A baffle is slidably installed in the socket hole, and a through hole is formed on the baffle. When the baffle moves in the socket hole, the through hole is aligned with or offset from the inflow channel. This allows the valve to block the inflow channel during storage or transportation, preventing dust and other impurities from entering and clogging the small-diameter inflow channel. This ensures the valve's performance after installation. During valve installation and use, the through hole and the inflow channel are aligned, avoiding the baffle's influence on normal valve operation and meeting the requirement for unobstructed flow after installation.

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 4 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0024] Figure 1 This is a structural diagram of an embodiment of a high-pressure valve with an inlet baffle according to the present invention; Figure 2 This is a cross-sectional view of an embodiment of a high-pressure valve with an inlet baffle according to this utility model. Figure 1 and Figure 2 As shown, the high-pressure valve with inlet baffle provided in this embodiment includes: a housing 1, a moving iron core assembly 2, a compression spring 3, a valve seat 4, a valve plug 5, and a baffle 6.

[0025] Specifically, a telescopic hole 11 is provided at the center of the housing 1, extending through both ends. Simultaneously, a coil assembly 12 is coaxially sleeved outside the telescopic hole 11 and located inside the housing 1 at one end. Furthermore, the moving iron core assembly 2 includes a moving iron core 21 and a sliding rod 22. During installation, the moving iron core 21 is positioned at one end of the coil assembly 12, allowing it to move when the coil assembly 12 generates a magnetic field. A compression spring 3 is provided on the side of the moving iron core 21 facing away from the coil assembly 12, allowing the compression spring 3 and the coil assembly 12 to act on both sides of the moving iron core 21 respectively. This allows the moving iron core 21 to return to its original position after being pushed by the coil assembly 12 by the force of the compression spring 3. In addition, one end of the slide rod 22 is fixed to the moving iron core 21, so that the slide rod 22 can move with the moving iron core 21. The other end of the slide rod 22 passes through the telescopic hole 11, that is, the telescopic hole 11 guides the movement of the slide rod 22. Preferably, a sliding sleeve is coaxially arranged in the telescopic hole 11. When the slide rod 22 passes through the telescopic hole 11, it also passes through the sliding sleeve. While being guided by the sliding sleeve, it can also reduce wear and extend service life. In addition, the valve seat 4 is set at the end of the housing 1 away from the coil assembly 12. At the same time, an inflow channel 41 is opened on the valve seat 4 along the axial direction of the slide rod 22. Several discharge channels 13 communicating with the inflow channel 41 are opened on the side wall of the valve seat 4 at the end of the housing 1. That is, the medium such as oil enters the valve body through the inflow channel 41 and then exits through the discharge channels 13. In addition, one end of the slide rod 22 extends through the telescopic hole 11 to the connection between the inflow channel 41 and the discharge channel 13, and sets the valve plug 5 at the connection between the inflow channel 41 and the discharge channel 13 and selectively contacts the slide rod 22. That is, after the medium such as oil enters from the inflow channel 41, it will push the valve plug 5. At this time, the slide rod 22 moves away from the valve plug 5 under the action of the coil assembly 12, allowing the valve plug 5 to move, thereby realizing the connection between the inflow channel 41 and the discharge channel 13. The flow rate is controlled by the distance of the slide rod 22 away from the valve plug 5. When the compression spring 3 pushes the slide rod 22 in the opposite direction to move towards the valve plug 5 and squeezes the valve plug 5 to the connection between the inflow channel 41 and the discharge channel 13, the inflow channel 41 and the discharge channel 13 are cut off, thereby closing the valve and meeting the valve use requirements.

[0026] Figure 3 This is a structural diagram of a baffle according to a preferred embodiment of the present invention. Figure 3As shown, the baffle 6 is disposed inside the valve seat 4. At this time, a through hole 61 is provided on the baffle 6. Meanwhile, an insertion hole 42 is provided on the valve seat 4 along the radial direction of the inflow channel 41. The insertion hole 42 is connected to the inflow channel 41, providing a condition for the baffle 6 to block the inflow channel 41. In addition, the baffle 6 is slidably installed in the socket 42. When the baffle 6 slides in the socket 42, it is either directly opposite to or offset from the inflow channel 41 through the hole 61. That is, during the production, transportation, sales and pre-installation stages, the baffle 6 can block the port of the inflow channel 41. At this time, the hole 61 is offset from the inflow channel 41, which prevents dust and other impurities from entering the inflow channel 41 and clogging the small-diameter inflow channel 41, thus ensuring the performance of the valve after installation. In the post-installation stage, the baffle 6 can be opened to open the port of the inflow channel 41. At this time, the hole 61 is directly opposite to the inflow channel 41, which avoids the baffle 6 affecting the normal use of the valve and meets the requirement of the inflow channel 41 being open after installation.

[0027] Figure 4 This is a cross-sectional view of the valve seat according to a preferred embodiment of the present invention. Figure 2 and Figure 4 As shown, the insertion hole 42 is a blind hole. When the baffle 6 is installed in the insertion hole 42, a spring piece 62 is also provided between the baffle 6 and the bottom of the insertion hole 42. The spring piece 62 holds the baffle 6 in place, limiting the position of the baffle 6 in the insertion hole 42. This prevents the baffle 6 from being excessively inserted into the insertion hole 42 when the valve is not installed, which would cause the through hole 61 and the inflow channel 41 to be aligned. This avoids the unexpected failure of the baffle 6 blocking the inflow channel 41. Under the action of external force, the spring piece 62 can be compressed, allowing the baffle 6 to continue to be inserted into the insertion hole 42, so that the through hole 61 on the baffle 6 is aligned with the inflow channel 41, meeting the usage requirements and making the structural design more reasonable.

[0028] More specifically, the spring piece 62 between the bottom of the baffle 6 and the insertion hole 42 is arranged at an angle along the length of the baffle 6. Preferably, the spring piece 62 and the baffle 6 are an integral structure. That is, when processing the spring piece 62, a groove can be cut on one side of one end of the baffle 6, and the cut part can be bent at an angle to one side, which makes processing more convenient.

[0029] More specifically, a protrusion is provided on one side of the baffle 6. This protrusion forms a limiting structure on the surface of the baffle 6. When the baffle 6 is slidably positioned within the insertion hole 42, the protrusion abuts against the wall of the insertion hole 42. Through the contact between the protrusion and the wall of the insertion hole 42, the baffle 6 can be temporarily confined within the insertion hole 42 without external force, preventing the baffle 6 from accidentally detaching from the insertion hole 42 when the valve is not installed. This ensures that the baffle 6 of an uninstalled valve always blocks the port of the inflow channel 41. It is worth noting that the protrusion is formed by stamping the baffle 6, which also facilitates processing and improves the overall structural integrity.

[0030] More specifically, a pressing slope 63 is provided at the end of the baffle 6 opposite to the end where the spring piece 62 is located. The pressing slope 63 is arranged at an angle to the direction of the insertion hole 42. When the through hole 61 and the inflow channel 41 are offset from each other, the pressing slope 63 is exposed outside the insertion hole 42. During subsequent installation, when the end of the valve with the valve seat 4 is connected to other supporting structural components, the protrusions on the other supporting structural components will contact and push against the pressing slope 63. The pressing slope 63 applies a component force towards the bottom of the insertion hole 42 to the baffle 6, so that the baffle 6 can compress the spring piece 62, thereby making the through hole 61 on the baffle 6 and the inflow channel 41 aligned. That is, the baffle 6 can be pushed during the valve installation process to open the inflow channel 41 without additional operation, making the installation more convenient.

[0031] More specifically, a recessed hole 14, coaxial with the telescopic hole 11, is also provided at one end of the housing 1 where the valve seat 4 is located. During installation, the valve seat 4 is embedded in the recessed hole 14, achieving a concealed installation of the valve seat 4 and avoiding space occupation. At the same time, a boss 43 is provided at the center of the end face of the valve seat 4 facing the outside of the housing 1. The boss 43 is part of the valve seat 4. At this time, the inflow channel 41 passes through the boss 43, and the insertion hole 42 is set in the boss 43. The boss 43 forms a stepped structure on the side of the valve seat 4 facing the outside of the housing 1, providing space for the external exposure of the extrusion slope 63 on the baffle 6, and also providing conditions for the protrusions on other supporting structural components to push against the extrusion slope 63.

[0032] More specifically, a clearance hole 44 is provided on the boss 43 at the opening of the insertion hole 42, and the clearance hole 44 is connected to the insertion hole 42. That is, the opening of the insertion hole 42 is expanded by the clearance hole 44, so that when the subsequent baffle 6 moves in the insertion hole 42, the extrusion ramp 63 can selectively enter into the clearance hole 44. That is, the extrusion ramp 63 can be pushed into the clearance hole 44, so that the baffle 6 can compress the spring 62 so that the through hole 61 is aligned with the inflow channel 41, avoiding the problem of the extrusion ramp 63 protruding outward and blocking the installation. The structural design is more reasonable.

[0033] More specifically, a sealing groove 45 is also provided inside the valve seat 4. At this time, a sealing groove 45 is provided in the inflow channel 41 and on both sides of the insertion hole 42. A sealing ring 46 is provided in each sealing groove 45. When the baffle 6 is inserted into the insertion hole 42, the two sealing rings 46 are respectively attached to the two sides of the baffle 6. That is, the two sealing rings 46 can maintain the use requirement of the baffle 6 moving in the insertion hole 42, and also maintain the sealing between the valve seat 4 and the baffle 6, avoiding the problem of leakage of oil and other media from the insertion hole 42, and better adapting to the high pressure environment.

[0034] More specifically, a cover 7 is provided at the end of the housing 1 away from the valve seat 4. At this time, a movable cavity 15 is also provided at the end of the housing 1 where the moving iron core 21 is located. The moving iron core 21 and the compression spring 3 are installed in the movable cavity 15 of the housing 1. When the cover 7 is installed on the housing 1, the cover 7 can cover the opening of the movable cavity 15, realizing external protection for the moving iron core 21, the compression spring 3 and other structures. At the same time, the end of the compression spring 3 away from the moving iron core 21 is pressed against the cover 7, so that the cover 7 can also serve as the base for the compression spring 3 to maintain the preload of the compression spring 3. The structural design is more reasonable.

[0035] More specifically, the valve plug 5 used to open, close, and regulate the connection between the inflow channel 41 and the discharge channel 13 is a steel ball. At the same time, a recessed ball cup is provided on the end face of the slide rod 22 near the valve plug 5. The ball cup and the spherical surface of the steel ball cooperate to make the end of the slide rod 22 act more stably on the valve plug 5, maintain the movement direction of the valve plug 5, and avoid the valve plug 5 from moving randomly and getting stuck unexpectedly.

[0036] The high-pressure valve with an inlet baffle provided in this embodiment includes a housing 1, a moving iron core assembly 2, a compression spring 3, a valve seat 4, a valve plug 5, and a baffle 6. A valve seat 4 with an inflow channel 41 is provided at one end of the housing 1. Simultaneously, a discharge channel 13 communicating with the inflow channel 41 is provided on the housing 1. The moving iron core assembly 2 is slidably disposed within the housing 1 and cooperates with the coil assembly 12 within it. The compression spring 3 presses against the moving iron core assembly 2. The slide rod 22 of the moving iron core assembly 2 extends to the connection point between the inflow channel 41 and the discharge channel 13 and selectively contacts the valve plug 5 at that point. Furthermore, the valve seat 4 extends along the inflow channel 4... The valve 1 has a radially provided insertion hole 42. At the same time, the baffle 6 has a through hole 61. When the baffle 6 moves within the insertion hole 42, the through hole 61 is directly opposite to or offset from the inflow channel 41. The offset arrangement of the through hole 61 and the inflow channel 41 can cover the inflow channel 41 with the baffle 6, preventing dust and other impurities from entering the smaller inflow channel 41 during storage, transportation, etc., and causing blockage. This ensures the performance after installation and also allows the inflow channel 41 to be normally open through the directly opposite through hole 61 and the inflow channel 41, maintaining the normal operation of the valve.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
