Description

Technical Field

[0001] This invention relates to the field of plug valve processing technology, specifically an automated turning equipment for valve production. Background Technology

[0002] In the modern intelligent manufacturing system of plug valves, high-precision, fully automated CNC turning centers have become the core equipment for valve body processing. These machines typically integrate industrial robots, automatic feeding mechanisms, multi-axis linkage CNC systems, and online testing units, aiming to achieve continuous, efficient, and unmanned processing of valve bodies from blanks to finished products, thereby significantly improving production efficiency and product consistency.

[0003] For example, a turning tooling for a cast plug valve body, as described in application number CN202420746529.7, includes a machining table, a drilling assembly, a dust extraction assembly, and a clamping assembly; the clamping assembly fixes the valve body so that the valve body will not move when drilling.

[0004] During use, as the cutting tool continues to turn the valve body, the valve body becomes thinner and thinner, the reaction force of the clamping components increases continuously, and the heat cannot be dissipated, making the valve body prone to breakage and thermal deformation.

[0005] In the turning process of plug valve core, two long-standing and interrelated technical bottlenecks—processing thermal deformation and structural fracture risk—remain key factors restricting the improvement of product quality and production yield. Therefore, it is necessary to invent an automated turning equipment for valve production to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an automated turning equipment for valve production, which aims to solve the problem of thermal deformation and structural fracture of the valve body during the turning process of the plug valve in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an automated turning equipment for valve production, comprising:

[0008] The base has a valve core fixedly connected to its top.

[0009] The clamping assembly is fixedly mounted on the upper side of the base and is used to clamp the valve core during valve core turning.

[0010] A support assembly, located on the upper side of the base, is used to adjust the reverse support force during valve core machining.

[0011] A distance detector, located inside the support assembly, is used to detect the distance the support assembly moves.

[0012] The spray assembly is movably connected inside the support assembly and is used to adjust the amount of coolant sprayed during the valve core turning process. As the valve core turning depth increases, the support assembly moves closer to the valve core end and increases the reverse support force on the valve core. The movement of the support assembly increases the amount of coolant sprayed by the spray assembly.

[0013] This invention clamps and fixes the valve core using a support assembly. During the valve core turning process, the reverse support force of the support assembly and the cooling efficiency of the coolant discharged by the spray assembly are adjusted according to the turning position. This effectively improves the stability and efficiency of valve core machining. The operation is simple, safe, and stable, facilitating large-scale mass production of valve cores. At the same time, it has high turning efficiency, good turning effect, meets actual processing needs, and has strong controllability and high adaptability.

[0014] Preferably, the base is fixedly installed on a flat ground, and its upper surface is a planar structure. A first slide rail and a second slide rail are arranged in the longitudinal direction in the upper central area of ​​the base. The first slide rail and the second slide rail are parallel to each other and run through the entire length of the base. The position of the first slide rail on the base is relatively close to the central axis. The two maintain a fixed distance and are used to movably install the cutting tool.

[0015] Preferably, a support rod is installed parallel to the length of the device above the first slide rail. The clamping assembly and the support rod are perpendicular to each other in the horizontal direction. The support rod and the first slide rail are coaxial and parallel. The tool is slidably connected between the first slide rail and the support rod through a sliding mechanism. The lower end of the tool forms a sliding fit with the first slide rail, and the upper end forms a limiting and guiding relationship with the support rod, so that the tool can move in the length direction of the base.

[0016] Preferably, the clamping assembly has a square shell structure. The lower end of the clamping assembly is fixedly connected to the upper left end face of the base. Its position is on the left extension line of the first slide rail and the second slide rail, which is used to provide a positioning reference for clamping the workpiece. After the valve core is clamped at the center position of the clamping assembly, its axis remains parallel to the support rod and the first slide rail.

[0017] Preferably, the support component includes;

[0018] The outer casing is slidably connected to the upper side of the second slide rail to provide support for the entire support assembly. The bottom of the outer casing has a sliding groove that is slidably connected to the second slide rail.

[0019] An arc-shaped ring, which has a ring structure and is fixedly connected to the upper side of the outer shell;

[0020] Support blocks are symmetrically arranged on the inner side of the arc-shaped ring;

[0021] The arc-shaped clamping component, which has a ring structure and is symmetrically fixed on the top of the support block, is used to provide support force for the valve core.

[0022] Preferably, the support component further includes;

[0023] The slider is tightly fitted to and slidably connected to the inner side of the arc-shaped clamp; the distance detector is fixedly connected to the inner wall of the slider to detect the distance value between the slider and the arc-shaped clamp.

[0024] The adjustment part has one end fixedly mounted on the side wall of the slider and the other end fixedly connected to the side wall of the arc-shaped clamping part.

[0025] The elastic part has its two ends connected to the top of the slider and the inside of the arc-shaped clamping part, respectively.

[0026] The pressing block is fixedly mounted on the top of the slider. The pressing block is elastic and is used to elastically clamp the valve core.

[0027] Preferably, the spray assembly includes;

[0028] The water storage cavity is located in the hollow area of ​​the outer shell and has a closed cavity structure;

[0029] The first arc-shaped cavity is connected to the water storage cavity. The first arc-shaped cavity extends circumferentially along the inner side of the arc-shaped ring. The first arc-shaped cavity is distributed around the outer ring of the valve core and maintains a concentric position with the valve core.

[0030] The channel runs through the interior of the support block and is centrally located.

[0031] The second arc-shaped cavity is located in the internal space of the arc-shaped clamping member and is symmetrically distributed along the outer periphery of the valve core. The second arc-shaped cavity is connected to the first arc-shaped cavity through a channel.

[0032] The water outlet is located inside the slider and is evenly distributed, surrounding the circumference of the valve core, so that it can form a close correspondence with the outer surface of the valve core in terms of position.

[0033] Preferably, the slider is tightly fitted to the inner side of the arc-shaped clamping member and located on the radial outer side of the valve core. A pressing block is fixedly installed on the top of the slider. The pressing block is located at the position closest to the valve core and is in relative contact with the outer surface of the valve core. The two are coaxially distributed. The elastic part is set between the inner top of the slider and the arc-shaped clamping member and extends in the radial direction. Its axis is perpendicular to the central axis of the valve core and plays a limiting role.

[0034] The beneficial effects of this invention are:

[0035] 1. When in use, the valve core receives uniform and stable lateral and radial support during the turning process through the synergistic action of the clamping and supporting components, effectively preventing deformation or breakage caused by cutting forces and ensuring machining accuracy and workpiece quality.

[0036] 2. When in use, the spray assembly continuously sprays and washes the valve core during the turning process through the built-in coolant circulation system, avoiding thermal deformation caused by local high temperature and further improving the processing quality.

[0037] 3. When in use, the present invention detects the movement distance of the slider by a distance detector, thereby accurately obtaining the valve core size and the smoothness of the outer surface, further improving the subsequent valve core turning efficiency and turning effect; at the same time, during the valve core turning process, the tool feed is adjusted by the distance value detected by the distance detector to ensure continuous and stable turning of the valve core.

[0038] 4. When the valve core breaks during the turning process, the distance value detected by the distance detector decreases, the spray assembly stops working and the support assembly returns to its original position, thereby stopping further turning of the valve core.

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0051] This invention provides, for example Figures 1 to 10 An automated turning machine for valve production is shown, comprising: a base 1, with a valve core 3 fixedly connected above the base 1; the valve core 3 is a structure to be turned, mainly having a hole machined at its axis to facilitate subsequent rotation and flow regulation within a plug valve; a clamping assembly 9, fixedly installed on the upper side of the base 1, used to clamp the valve core 3 during the turning process, i.e., the valve core 3 is installed inside the clamping assembly 9 and clamped, thereby improving the stability and clamping performance of the valve core 3 during subsequent processing; a support assembly 4, located on the upper side of the base 1, used to adjust the reverse support force during the turning of the valve core 3 to prevent breakage or deformation; during the processing of the valve core 3, the support assembly 4 continuously adjusts the support force, thereby effectively ensuring the efficiency and safety of the valve core 3 processing; and a distance detector. 11, which is set inside the support assembly 4, is used to detect the moving distance of the support assembly 4; the setting of the distance detector 11 can accurately obtain the diameter of the valve core 3 and the turning feed. The spray assembly 5, which is set inside the support assembly 4, is used to provide a cooling liquid spray volume during the turning process of the valve core 3 to prevent thermal deformation. During the machining of the valve core 3, the spray assembly 5 continuously sprays coolant onto the valve core 3, thereby achieving cooling and temperature reduction of the valve core 3. The amount of coolant sprayed is adjusted according to the temperature value change of the valve core 3, thereby further achieving an adaptive cooling and adjustment effect. When the turning depth of the valve core 3 increases, the amount of movement of the support assembly 4 towards the end of the valve core 3 increases and the reverse support force on the valve core 3 increases. The movement of the support assembly 4 increases the amount of coolant sprayed by the spray assembly 5.

[0052] The base 1 is fixedly installed on a flat ground. Its upper surface is a planar structure. In the upper central area of ​​the base 1, a first slide rail 6 and a second slide rail 7 are arranged parallel to each other in the longitudinal direction. The arrangement of the first slide rail 6 and the second slide rail 7 facilitates the movement and adjustment of the upper tool 10, thereby improving the turning accuracy and turning effect of the valve core 3. The first slide rail 6 and the second slide rail 7 are parallel to each other and run through the entire length of the base 1. They maintain a fixed distance from each other and the tool 10 is movably installed. The tool 10 works continuously and turns the valve core 3. Specifically, during the turning of the valve core 3, the tool 10 rotates while the valve core 3 does not rotate. At the same time, the tool 10 can adjust its own height and the distance it moves along the first slide rail 6 according to the actual processing needs. This arrangement facilitates the machining of the required hole inside the valve core 3.

[0053] A support rod 2 is installed parallel to the length of the equipment above the first slide rail 6. The support rod 2 is coaxial and parallel to the first slide rail 6. The cutter 10 is installed between the first slide rail 6 and the support rod 2 through a sliding mechanism. The support rod 2 provides limiting support for the movement of the cutter 10, further improving the stability and efficiency of the movement of the cutter 10. The lower end of the cutter 10 forms a sliding fit with the first slide rail 6, and the upper end forms a limiting guide relationship with the support rod 2, so that the cutter 10 can move stably in the length direction of the base 1. The position of the first slide rail 6 on the base 1 is relatively close to the central axis.

[0054] The clamping assembly 9 has a square shell structure. The clamping assembly 9 and the support rod 2 are perpendicular to each other in the horizontal direction. The clamping assembly 9 stably clamps the valve core 3 and can drive the valve core 3 to rotate. The lower end of the clamping assembly 9 is fixedly connected to the upper left end face of the base 1. Its position is on the left extension line of the first slide rail 6 and the second slide rail 7, which is used to provide a positioning reference for the workpiece clamping. After the valve core 3 is clamped at the center position of the clamping assembly 9, its axis is parallel to the support rod 2 and the first slide rail 6. Therefore, the tool 10 moves above the first slide rail 6 and realizes stable and accurate turning of the valve core 3.

[0055] The support assembly 4 includes: a housing 403, which is slidably connected to the upper side of the second slide rail 7 to provide support for the entire support assembly 4; the movement of the housing 403 synchronously drives the entire support assembly 4 to move; a groove 8 is provided at the bottom of the housing 403, which is slidably connected to the second slide rail 7; the groove 8 facilitates the stable sliding of the housing 403 above the second slide rail 7; an arc-shaped ring 404, which is an annular structure and fixedly connected to the upper side of the housing 403; the arc-shaped ring 404 correspondingly wraps around the valve core 3, further improving the accuracy and comprehensiveness of the support and cooling of the valve core 3; a support block 402, which is symmetrically arranged inside the arc-shaped ring 404; and an arc-shaped clamping member 401, which is an annular structure and symmetrically fixedly arranged on the top of the support block 402 to provide support for the valve core 3; the support block 402 not only supports and fixes the arc-shaped clamping member 401, but also allows the internally flowing coolant to further enter the arc-shaped clamping member 401 and achieve cooling of the valve core 3.

[0056] The support assembly 4 also includes: a slider 407, which is tightly fitted to and slidably connected to the inner side of the arc-shaped clamping member 401; the slider 407 moves inside the arc-shaped clamping member 401 and adjusts the clamping force on the valve core 3 accordingly, thereby ensuring the force balance of the valve core 3 during the turning process; an adjustment part 406, one end of which is fixedly and symmetrically arranged on the side wall of the slider 407, and the other end is fixedly connected to the side wall of the arc-shaped clamping member 401, which is made of heat-sensitive material and expands radially when heated; as the turning width of the valve core 3 increases, the temperature value at the adjustment part 406 increases continuously, and the adjustment part 406 expands continuously; and an elastic part 408, which... The two ends are respectively connected to the top of the slider 407 and the inside of the arc-shaped clamping member 401; the elastic part 408 is elastic and provides elastic support to the slider 407; the pressing block 405 is fixedly set at the top of the slider 407, and the pressing block 405 is elastic and is used to elastically clamp the valve core 3, thereby further improving the clamping effect on the valve core 3; the distance detector 11 is fixedly connected to the inner wall of the slider 407 and is used to detect the distance value between the slider 407 and the arc-shaped clamping member 401. By detecting the change in the distance value through the distance detector 11, the corresponding sliding distance value of the slider 407 is obtained, and the feed amount for turning is further obtained to ensure the turning accuracy.

[0057] The spray assembly 5 includes: a water storage chamber 502, located in the hollow area of ​​the outer shell 403, forming a closed cavity structure; coolant flows inside the water storage chamber 502, and the inlet end of the water storage chamber 502 is connected to the coolant tank through a pump body; a first arc-shaped cavity 501, directly connected to the water storage chamber 502, extending circumferentially along the inner side of the arc-shaped ring 404, distributed around the outer ring of the valve core 3, and maintaining a concentric position with the valve core 3; the coolant inside the water storage chamber 502 continues to flow and reaches the inside of the first arc-shaped cavity 501; a channel 505, penetrating the interior of the support block 402, is centrally located; the coolant inside the first arc-shaped cavity 501 enters the channel 505. Inside the 05, the second arc-shaped cavity 503 is located in the internal space of the arc-shaped clamping member 401 and is symmetrically distributed along the outer periphery of the valve core 3. The second arc-shaped cavity 503 is connected to the first arc-shaped cavity 501 through the channel 505. The coolant inside the channel 505 enters the interior of multiple second arc-shaped cavities 503. The outlet 504 is located inside the slider 407 and is evenly distributed, surrounding the circumference of the valve core 3. The outlet 504 is inclined and faces the valve core 3, so that it can form a close correspondence with the outer surface of the valve core 3 in position. The coolant inside the second arc-shaped cavity 503 is discharged at high speed through multiple outlets 504 to cool down the valve core 3 and remove impurities.

[0058] When the adjusting part 406 expands due to heat, it synchronously drives the slider 407 to move. The slider 407 fits tightly against the inner side of the arc-shaped clamp 401 and is located on the radial outer side of the valve core 3. The coolant inside the second arc-shaped cavity 503 will not be discharged through the gap between the slider 407 and the arc-shaped clamp 401. It can only continuously enter the interior of the slider 407 and finally be discharged at high speed through the outlet 504. The pressing block 405 is located closest to the valve core 3 and is in relative contact with the outer surface of the valve core 3. The two are coaxially distributed. The setting of the pressing block 405 further improves the elastic pressing effect on the valve core 3. The elastic part 408 is set between the inner top of the slider 407 and the arc-shaped clamp 401, extending in the radial direction. Its axis is perpendicular to the central axis of the valve core 3 and plays a limiting role. When the volume of the adjusting part 406 decreases, the slider 407 is driven to move in the opposite direction under the elastic force of the elastic part 408.

[0059] In use, the equipment is fixedly installed on a flat ground via the base 1. The support rod 2 and the first slide rail 6 on the upper part of the base 1 cooperate to provide guidance and support for the movement of the tool 10. The valve core 3 to be processed is placed in the clamping assembly 9, which provides the main clamping force and circumferential positioning. The support assembly 4 is slidably connected to the second slide rail 7 on the base 1 via the slide groove 8 at the bottom of its outer shell 403, allowing it to move axially along the valve core 3. The support assembly 4 slides accurately to the cantilever section below the valve core 3 that requires reinforced support. Then, the pump is started, and the coolant inside the water storage chamber 502 continuously enters the second arc chamber 503 along the first arc-shaped cavity 501 and the channel 505. The cooling pressure inside the second arc chamber 503 continuously increases and drives the slider 407 to move closer to the valve core 3. The movable pressing block 405 elastically presses against the outer surface of the valve core 3, and works in conjunction with the adjusting part 406 and the elastic part 408 to elastically connect the slider 407, forming a uniform and elastic basic support ring. This prevents the valve core from flexing and deforming in the initial state, further improving the shock absorption and buffering effect of the subsequent cutting tool 10 on the valve core 3 during turning. It also avoids the valve core 3 from colliding and being squeezed by the slider 407 for a long time during continuous turning, thus preventing damage to its own structure. As the slider 407 moves, it synchronously drives the distance detector 11 to move. The distance value detected by the distance detector 11 continuously increases and reaches the preset distance value, indicating that the slider 407 drives the pressing block 405 to the appropriate position and elastically presses and fixes it to the valve core 3, further improving the accuracy and efficiency of clamping the valve core 3.

[0060] Simultaneously, the clamping assembly 9 drives the valve core 3 to rotate. The valve core 3 rotates continuously inside the support assembly 4, and the outer surface of the valve core 3 continuously rotates and presses against multiple pressing blocks 405. If the outer surface of the valve core 3 is smooth and has the same diameter, the distance values ​​detected by multiple distance detectors 11 will not change. However, if there is a protrusion at a certain position on the outer surface of the valve core 3, the clamping assembly 9 drives the valve core 3 to rotate continuously and elastically press against the pressing block 405. The pressing block 405 synchronously drives the slider 407 to move in the opposite direction. The distance value detected by the distance detector 11 decreases and is less than the preset distance value. Therefore, the valve core 3 needs to be removed and reprocessed for subsequent turning. This process can be used to pre-inspect the valve core 3, effectively improving the accuracy of subsequent turning.

[0061] At the same time, during the movement of the slider 407, multiple outlets 504 are moved and slide out of the arc-shaped clamping member 401. The coolant inside the second arc-shaped cavity 503 is continuously discharged along the outlet 504 located outside the arc-shaped clamping member 401, thereby achieving precise cooling and impurity removal at the turning position of the valve core 3, and avoiding excessive temperature during the turning process of the valve core 3 and affecting its own strength.

[0062] When the lathe tool 10 begins machining and moves laterally to the area of ​​the valve core 3 directly above a set of support components 4, the cutting force in this area is at its maximum, and the temperature rises sharply. The valve core 3 exhibits a tendency to bend and deform. This deformation tendency is directly converted into additional pressure on the pressing block 405 directly below. This process triggers a coordinated response between the support component 4 and the spray component 5. The cutting heat is conducted to the adjustment part 406 in this area, causing it to expand due to heat. The expansion of the adjustment part 406 pushes the slider 407 to produce an additional outward displacement. This pressure is transmitted to the slider 407 of this set, forcing the slider 407 to overcome the increased tension of the elastic part 408. This displacement causes the supporting force of the pressing block 405 on the valve core 3 to increase sharply, forming a strong local support point. This effectively counteracts the deformation caused by the cutting force, ensuring the machining accuracy of this point, while preventing the valve body 3 from deforming and breaking.

[0063] As the turning feed gradually increases, the cutting force in the area gradually increases, and the temperature gradually rises, causing the regulating part 406 to continuously expand due to heat. The expansion of the regulating part 406 pushes the slider 407 to continuously move outward. The movement of the slider 407 causes more of its internal water outlets 504 to move outward along the arc-shaped clamping member 401 and be exposed. The coolant from the second arc-shaped cavity 503 then sprays through these exposed water outlets 504 with a larger flow rate and a wider coverage area onto the high-temperature valve core 3 surface and the tool 10 area, further improving the cooling effect on the outer surface of the valve core 3, avoiding the valve core 3 from overheating and causing its own thermal deformation and other dangers. In addition, the increased coolant further improves the flow and impurity removal effect at the tool 10 position, preventing the accumulation of chips and other debris generated during the turning of the valve core 3 at the tool 10 and affecting subsequent turning, effectively achieving precise cooling and chip flushing.

[0064] Since the valve core 3 is mostly cylindrical, during the turning process of the valve core 3 by the tool 10, the thickness value at both sides of the valve core 3 is less than that at the center. Therefore, the thermal expansion of the adjustment part 406 on both sides increases and is greater than that at the center. The adjustment part 406 drives the slider 407 to move closer to the valve core 3, and the distance value detected by the distance detector 11 increases. Each distance value is the preset distance value set at that position. This preset distance value can be obtained through multiple experiments. The slider 407 drives the pressing block 405 to increase the supporting force on both sides of the valve core 3. At the same time, the movement of the slider 407 drives the outlet 504 to move outward by an increased amount, and the amount of coolant discharged from the outlets 504 on both sides increases. Therefore, the valve core 3 effectively achieves fixed-point support and precise cooling, meets the special turning requirements of the valve core 3, and has stronger adaptability and higher precision.

[0065] Meanwhile, as the cutting tool 10 completes turning at this position and moves to the next position, the temperature at the adjusting part 406 decreases, causing the adjusting part 406 to cool and shrink. Subsequently, under the pulling force of the elastic part 408, the slider 407 is pulled back to the initial position. The slider 407 drives the pressing block 405 to move in the opposite direction, reducing the pressing force of the pressing block 405 on the valve core 3. This effectively avoids problems such as the pressing block 405 pressing the valve core 3 elastically for a long time, causing structural damage and deformation. At the same time, when the slider 407 moves, it simultaneously drives multiple outlets 504 to move in the opposite direction. The second arc cavity 503 increases the amount of blockage on the outlets 504, reducing the amount of coolant discharged from the outlets 504, thus avoiding problems such as continuous discharge of coolant and waste.

[0066] If the feed rate of the tool 10 increases, the heat generated during the turning process of the tool 10 and the valve core 3 will increase. The adjustment unit 406 will drive the slider 407 to move closer to the valve core 3 by an increased amount and greater than the set movement difference. The distance value detected by the distance detector 11 is greater than the preset distance value set at this position. Therefore, the valve core 3 is prone to structural damage under this feed rate. Thus, it is necessary to control the tool 10 to reduce the feed rate to ensure that the tool 10 continuously and stably feeds and turns the valve core 3.

[0067] The group support component 4 is reset and ready to respond to the next machining cycle. The above process is repeated continuously to perform multi-stage reciprocating turning of the valve core 3, thereby improving the turning accuracy of the valve core 3. During the movement of the tool 10, the adjustment part 406 drives the slider 407 to move back and forth. The elastic pressing force of the slider 407 on the valve core 3 through the pressing block 405 at the end changes continuously, thereby improving the machining strength of the valve core 3. This avoids problems such as bending deformation or even breakage of the side wall of the valve core 3 due to different turning forces during the machining process. In addition, during the movement of the slider 407, multiple water outlets 504 are moved simultaneously. The amount of coolant discharged from the second arc cavity 503 along the water outlet 504 changes continuously, further realizing the pulse flushing effect on the outer surface of the valve core 3. While ensuring that the temperature value at the turning point of the valve core 3 meets the requirements, the pulse flushing effect on the debris generated during the turning of the valve core 3 is further improved, preventing the debris from hindering the subsequent machining of the valve core 3.

[0068] Due to material issues with the valve core 3, the cutting tool 10 suddenly breaks at the machining position during the turning process. As a result, the pressure between the cutting tool 10 and the valve core 3 decreases and the heat generated decreases. The volume of the adjusting part 406 decreases and drives the slider 407 to move away from the valve core 3. The distance value detected by the distance detector 11 decreases and is much smaller than the preset distance value set at this feed rate. Therefore, it is not necessary to continue machining the valve core 3. The cutting tool 10 and the pump body both stop working. Coolant is no longer introduced into the second arc-shaped cavity 503. Under the elastic force of the elastic part 408, the slider 407 moves in the opposite direction to return to its original position. The slider 407 drives the pressing block 405 to move in the opposite direction and no longer elastically presses the valve core 3. The valve core 3 is removed along the clamping assembly 9, a new valve core 3 is replaced, and the above process is repeated for turning.

[0069] Once the valve core 3 has been completely machined, stop the cutting tool 10 and stop the coolant from flowing into the spray assembly 5. Remove the support assembly 4 and the valve core 3 can be removed from the clamping assembly 9.

[0070] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0071] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
