Description

Technical Field

[0001] This invention belongs to the field of valve processing technology, and relates to a thin-walled pure aluminum gas valve that is not easily deformed and its processing method. Background Technology

[0002] Natural gas, as a new energy source for engines, can effectively reduce vehicle emissions, decrease pollution, and save costs. The gas fuel injection valve controls the engine's intake air volume, precisely matching the air and natural gas drawn into the engine; therefore, it is a key component of the engine's fuel supply system. Existing gas fuel injection valves often have uneven shapes and thicknesses, and their inner grooves are too small, adding significant technical challenges. This necessitates additional processing steps and molds to compensate for these deficiencies, resulting in considerable raw material waste, higher costs, and increased susceptibility to deformation during installation, affecting installation accuracy.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, Chinese patent discloses a valve processing method [application number: 201910721346.3], including: a) valve body manufacturing: inspecting the purchased castings, performing ultrasonic flaw detection, surfacing welding and post-weld heat treatment on qualified castings, and grinding the sealing surface of the castings; b) valve internals manufacturing process: inspecting the purchased raw materials, making the raw materials into blanks, and then performing ultrasonic flaw detection on the blanks. The qualified blanks undergo welding and post-weld heat treatment, and the sealing surfaces of the blanks are ground; c) End cap processing: The blanks in step b include end cap blanks. The end caps are placed on a drilling device, and threaded holes are punched on the end caps to complete the processing; d) Fastener manufacturing; e) Final assembly: After cleaning the manufactured parts, rough assembly is performed. Then, the assembled valve undergoes a water pressure test. After passing the test, it is disassembled, cleaned, and then the parts are reassembled and tested with the actuator. After testing, the valve surface is painted, and then the valve is packaged and transported. However, the valve body processed by this method still has the defects of uneven wall thickness and easy deformation. Summary of the Invention

The top of the valve body is provided with several reinforcing plates symmetrically arranged along the center line of the valve body. The reinforcing plates are arc-shaped. An anti-torque connecting rod is provided between the reinforcing plate and the fixing block. One end of the anti-torque connecting rod is connected to the valve body, and the other end of the anti-torque connecting rod is connected to the reinforcing plate.

[0010] In the aforementioned thin-walled pure aluminum gas valve that is not easily deformed, the anti-torque connecting rod is parallel to the valve body, and a reinforcing rib is provided between the anti-torque connecting rod and the valve body.

The inlet end is provided with a first external thread, and the outlet end is provided with a second external thread. The first external thread and the second external thread have the same thread diameter.

[0011] A method for processing a thin-walled pure aluminum gas valve that is not easily deformed includes the following steps:

[0012] Step 1: Manufacturing the main body of the valve, inspecting the pure aluminum blank for flaws, and selecting qualified blank raw materials;

[0013] Step 2: Die-cast the valve body blank to form a valve body with uniform wall thickness;

[0014] Step 3: Drill holes in the valve body, machine clearance grooves, and tap the port threads;

[0015] Step 4: Machining the valve body and valve port on a high-precision lathe;

[0016] Step 5: Clean the grease;

[0017] Step Six: Assemble the parts.

[0018] In the above-mentioned processing method for a thin-walled pure aluminum gas valve that is not easily deformed, the specific operation in step one is as follows: use an ultrasonic flaw detection device to detect flaws in the pure aluminum blank, remove unqualified blank raw materials, and send qualified blank raw materials to the next process.

[0019] In the above-mentioned processing method for a thin-walled pure aluminum gas valve that is not easily deformed, the specific operation in step two is as follows: the operator puts the pure aluminum blank into the furnace and heats it to 661℃~800℃ in the furnace to become liquid aluminum. The liquid aluminum is then die-cast into a mold through a die-casting machine. The forming cavity wall of the mold is of uniform thickness. After the liquid aluminum is die-cast into the mold in step two, the mold is removed and cooled to obtain a preliminarily formed valve body. The valve body is then deburred.

[0020] In the above-mentioned processing method for a thin-walled pure aluminum gas valve that is not easily deformed, the specific operation in step three is as follows: the valve body is placed on a drilling machine and fixed. Then, a drill bit is used to drill holes in the valve body to form a deformation-resistant clearance groove. After forming the deformation-resistant clearance groove, a drill bit is used to drill holes in the top of the valve body to form a top clearance groove. After forming the top clearance groove, a drill bit is used to drill holes in the bottom of the valve body to form an elastic member clearance groove. After the drilling in step three is completed, the valve body is placed in an automatic thread lathe, and the inlet and outlet ends of the valve body are machined with external threads in sequence. After the external threads are machined, a spray gun is used to remove the debris on the inlet and outlet ends.

[0021] In the above-mentioned processing method for a thin-walled pure aluminum gas valve that is not easily deformed, the specific operation in step four is as follows: the valve body is placed in a CNC lathe, the valve body is clamped and fixed using a fixture, the CNC lathe is started, the speed is controlled at 1500 rpm to 2500 rpm, and the valve port is machined using an internal round cutter. After the valve port is machined in step four, the CNC lathe speed is controlled at 1300 rpm to 1500 rpm, and the valve port is chamfered using a chamfering cutter. After the machining is completed, the valve body is removed, and the debris on the valve body is removed using a spray gun.

[0022] In the above-mentioned processing method for a thin-walled pure aluminum gas valve that is not easily deformed, the specific operation in step five is as follows: the worker uses a neutral cleaning agent to thoroughly clean and remove dirt from the valve body. The specific operation in step six is ​​as follows: after assembling the ball valve, rotating rod and rotating wrench, they are passed through the fixing block and assembled to the valve body. The reinforcing plate and reinforcing rib are connected to the top of the valve body by welding. The welding temperature is controlled at 100℃~150℃. The spring is placed in the elastic part clearance groove and fixedly connected to the valve body. The buffer anti-deformation base plate is fixedly connected to the spring to complete the assembly.

[0023] Compared with existing technologies, the advantages of this invention are:

[0024] 1. The valve body of the present invention is made of pure aluminum. Pure aluminum has a high density and will not produce air holes or sand holes, ensuring airtightness requirements and reducing the machining allowance of the valve port surface. Since the air inlet and outlet are prone to deformation, anti-deformation relief grooves are set so that even if deformation occurs, it will not affect the appearance or the accuracy during processing and installation. The valve body has a uniform wall thickness, is easy to process, and saves raw materials, making it economical and practical.

[0025] 2. By setting a buffer anti-deformation base plate and elastic elements, the present invention can reduce the impact on the bottom of the valve body during installation. Even if a collision occurs, the buffer anti-deformation base plate can still play a buffering and protective role, increasing the service life of the valve body.

[0026] 3. By setting up a reinforcing plate and an anti-torque connecting rod, the present invention can improve the strength of the valve body when the valve body is bent by external force, prevent the valve body from easily twisting, and further improve the service life of the valve body. The reinforcing rib further strengthens the strength of the valve body and improves its stability.

[0027] 4. This invention transforms blind holes into through holes by avoiding them, which solves the problem of coolant carrying away distributed residues during processing, reduces the amount of aluminum chips sticking to the tool, and ensures dimensional accuracy.

[0028] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3As shown, a thin-walled pure aluminum gas valve that is not easily deformed includes a valve body 1. The valve body 1 has an inlet end 2 and an outlet end 3. The valve body 1 is made of pure aluminum and has a uniform wall thickness. The valve body 1 has several anti-deformation relief grooves 4 symmetrically arranged along the center line of the valve body 1. The inlet end 2 and the outlet end 3 correspond to the positions of the anti-deformation relief grooves 4. The bottom of the valve body 1 has a buffer anti-deformation base plate 5, which is connected to the valve body 1 by an elastic element. The bottom of the valve body 1 has several elastic relief grooves 6 symmetrically arranged along the center line of the valve body 1. The elastic element includes... A spring 7 is located in the elastic member clearance groove 6. One end of the spring 7 is connected to the valve body 1, and the other end of the spring 7 is connected to the buffer anti-deformation base plate 5. The buffer anti-deformation base plate 5 is provided with several anti-side sliders 8 symmetrically arranged along the center line of the buffer anti-deformation base plate 5. The valve body 1 is provided with several anti-side abutting blocks 9 symmetrically arranged along the center line of the valve body 1. The anti-side abutting blocks 9 abut and cooperate with the anti-side sliders 8. The anti-side slider 8 is provided with an anti-detachment limiting groove 10 at the end near the anti-side abutting block 9. The anti-detachment limiting block 11 extending into the anti-detachment limiting groove 10 is provided at the end of the anti-side abutting block 9 away from the valve body 1. The anti-side abutting block 9 is made of elastic rubber material.

[0036] In this embodiment, the valve body 1 is made of pure aluminum. Pure aluminum has a high density and will not produce air holes or sand holes, ensuring airtightness requirements and reducing the machining allowance of the valve port surface. Since the inlet end 2 and outlet end 3 are prone to deformation, the anti-deformation relief groove 4 is provided so that even if deformation occurs, it will not affect the appearance or the accuracy during processing and installation. The valve body 1 has a uniform wall thickness, is easy to process, and saves raw materials, making it economical and practical. At the same time, by providing a buffer anti-deformation base plate 5 and an elastic element, collisions to the bottom of the valve body 1 can be reduced during installation. Even if a collision occurs, the buffer anti-deformation base plate 5 can still provide buffer protection, increasing the service life of the valve body 1. The elastic relief groove 6 is used to house the spring 7. When an external impact force hits the buffer anti-deformation base plate 5, the elastic force of the spring 7 can absorb part of the impact force, providing a buffering effect on the valve body 1 and preventing the valve body 1 from being directly subjected to impact force, thus increasing the service life of the valve body 1. When the buffer anti-deformation base plate 5 is subjected to a side impact, the side-impact blocking block 9 and the side-impact sliding block 8 abut against each other, preventing the side impact force from directly impacting the valve body 1 and protecting the side of the valve body 1. When the buffer anti-deformation base plate 5 moves up and down, the sliding engagement between the anti-detachment limiting block 11 and the anti-detachment limiting groove 10 prevents the side-impact sliding block 8 from disengaging from the side-impact blocking block 9. Those skilled in the art should understand that the side-impact blocking block 9 can be made of natural rubber, butadiene rubber, or isoprene rubber, which has a good effect on absorbing side impact force.

[0037] Combination Figure 1 As shown, the top of the valve body 1 is provided with a top clearance groove 12. A stop ball valve 13 is rotatably provided inside the valve body 1. A ventilation channel 14 is provided inside the stop ball valve 13. A rotating rod 15 is provided at the top of the stop ball valve 13, which passes through the top clearance groove 12. A fixing block 16 is provided at the top of the valve body 1. The fixing block 16 is located above the top clearance groove 12 and the cross-sectional area of ​​the fixing block 16 is larger than the cross-sectional area of ​​the top clearance groove 12. The rotating rod 15 is rotatably engaged with the fixing block 16. A rotating wrench 17 is provided at the top of the rotating rod 15. The rotating wrench 17 is perpendicular to the rotating rod 15.

[0038] In this embodiment, by setting a top clearance groove 12, the blind hole is transformed into a through hole through clearance, which solves the problem of coolant carrying away distributed residue during processing, reduces the amount of aluminum chips sticking to the tool, and ensures dimensional accuracy. By rotating the rotating rod 15, the check / stop ball valve 13 can be rotated, thereby realizing the passage or stop of gas in the valve body. The venting channel 14 is used to pass gas. The fixing block 16 is located above the top clearance groove 12 and the cross-sectional area of ​​the fixing block 16 is larger than the cross-sectional area of ​​the top clearance groove 12 to avoid air leakage. When it is necessary to rotate the check / stop ball valve 13, the operator rotates the rotating wrench 17 to drive the rotating rod 15 and the check / stop ball valve 13 to rotate synchronously.

[0039] Combination Figure 1 , Figure 2 As shown, the fixing block 16 is provided with a first wrench abutment plate 18 and a second wrench abutment plate 19. The first wrench abutment plate 18 and the second wrench abutment plate 19 are respectively abutted and engaged with the rotating wrench 17. The first wrench abutment plate 18 and the second wrench abutment plate 19 are perpendicular to each other. The top of the air valve body 1 is provided with several reinforcing plates 20 symmetrically arranged along the center line of the air valve body 1. The reinforcing plates 20 are arc-shaped. An anti-torque connecting rod 21 is provided between the reinforcing plate 20 and the fixing block 16. One end of the anti-torque connecting rod 21 is connected to the air valve body 1, and the other end of the anti-torque connecting rod 21 is connected to the reinforcing plate 20.

[0040] In this embodiment, when ventilation is required, the rotary wrench 17 is rotated to abut against the second wrench abutment plate 19, connecting the ventilation channel 14 to the inlet end 2 and the outlet end 3. When the valve needs to be closed, the rotary wrench 17 is rotated to abut against the first wrench abutment plate 18, isolating the ventilation channel 14 from the inlet end 2 and the outlet end 3, thus achieving closure. By setting the reinforcing plate 20 and the anti-torque connecting rod 21, the strength of the valve body 1 can be improved when the valve body 1 is bent by external force, preventing the valve body 1 from easily twisting, and further improving the service life of the valve body 1.

[0041] The anti-torque connecting rod 21 is parallel to the valve body 1. A reinforcing rib 22 is provided between the anti-torque connecting rod 21 and the valve body 1. One end of the reinforcing rib 22 is connected to the anti-torque connecting rod 21, and the other end of the reinforcing rib 22 is connected to the valve body 1. The reinforcing rib 22 further strengthens the valve body 1 and improves its stability.

[0042] The reinforcing plate 20 and the reinforcing rib 22 are parallel to each other. A supporting reinforcing rod 23 is provided between the reinforcing plate 20 and the reinforcing rib 22. One end of the supporting reinforcing rod 23 is connected to the reinforcing plate 20, and the other end of the supporting reinforcing rod 23 is connected to the reinforcing rib 22. The air inlet 2 is provided with a first external thread 24, and the air outlet 3 is provided with a second external thread 25. The first external thread 24 and the second external thread 25 have the same thread diameter.

[0043] In this embodiment, the support and reinforcement rod 23 connects the reinforcement plate 20 and the reinforcing rib 22, further improving the stability of the structure. The first external thread 24 and the second external thread 25 are used for screw connection. The first external thread 24 and the second external thread 25 have the same thread diameter. The air inlet end and the air outlet end can be interchanged without affecting the use, and no judgment is required.

[0044] The working principle of this invention is:

[0045] The valve body 1 is made of pure aluminum. Pure aluminum has a high density and will not produce air holes or sand holes, ensuring airtightness requirements and reducing the machining allowance of the valve port surface. Since the air inlet end 2 and the air outlet end 3 are prone to deformation, the anti-deformation relief groove 4 is set to ensure that even if deformation occurs, it will not affect the appearance or the accuracy during processing and installation. The wall thickness of the valve body 1 is uniform, easy to process and saves raw materials, making it economical and practical. At the same time, by setting the buffer anti-deformation base plate 5 and elastic element, the collision with the bottom of the valve body 1 can be reduced during installation. Even if a collision occurs, the buffer anti-deformation base plate 5 can also play a buffer protection role, increasing the service life of the valve body 1. When the buffer anti-deformation base plate 5 moves up and down, the sliding cooperation between the anti-disengagement limit block 11 and the anti-disengagement limit groove 10 prevents the anti-side slider 8 from disengaging from the anti-side abutment block 9.

[0046] When the buffer anti-deformation base plate 5 is subjected to a side impact, the side impact force is prevented from directly impacting the valve body 1 through the abutting action between the side abutting block 9 and the side abutting slider 8, and the side of the valve body 1 is also protected. The side abutting block 9 can be made of natural rubber, butadiene rubber or isoprene rubber, and has a good effect on absorbing side impact force.

[0047] When ventilation is required, turn the lever 17 to abut against the second lever abutment plate 19, so that the ventilation channel 14 is connected to the air inlet 2 and the air outlet 3. When the valve needs to be closed, turn the lever 17 to abut against the first lever abutment plate 18, so that the ventilation channel 14 is isolated from the air inlet 2 and the air outlet 3, thereby achieving closure.

[0048] By setting the reinforcing plate 20 and the anti-torque connecting rod 21, the strength of the valve body 1 can be improved when the external force bends it, preventing the valve body 1 from easily twisting and further improving the service life of the valve body 1. The reinforcing rib 22 further strengthens the strength of the valve body 1 and improves its stability. The supporting reinforcing rod 23 connects the reinforcing plate 20 and the reinforcing rib 22, further improving the stability of the structure. The first external thread 24 and the second external thread 25 are used for screw connection. The first external thread 24 and the second external thread 25 have the same thread diameter. The air inlet end and the air outlet end can be interchanged without affecting the use and no judgment is required.
