Description

Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to the assembly and fixing mechanism of magnet and round cover in gas self-closing valve. Background Technology

[0002] Gas is a widely used gaseous fuel. Due to its flammable, explosive, and toxic properties, leaks can easily cause major safety accidents. Therefore, it is necessary to ensure that the gas entering the appliance is maintained at a normal pressure so that it can burn completely and stably. Currently, a gas self-closing valve is installed before the appliance to automatically shut off the valve in case of overpressure or underpressure, preventing gas leaks.

[0003] For example, the gas self-closing valve disclosed in patent application number 202320507447.2 includes a valve body, a valve core assembly, a flow valve, and a ball valve. The valve body includes a lower housing and an upper cover. The lower housing has an inlet and an outlet. The inlet end is connected to the flow valve, and the outlet end is connected to the ball valve. A valve seat and a valve core assembly are disposed in the cavity formed by the upper cover and the lower housing. The valve seat has a valve port that connects the inlet and the outlet. The valve core assembly includes a knob, a lifting button, a connecting rod, a diaphragm, a magnet, a slider, and a sealing gasket. The lifting button is located on the top of the upper cover. The connecting rod is telescopically coordinated with the upper cover. A red knob is located inside the lifting knob and telescopically coordinated with it. The red knob is fixedly connected to the upper end of the connecting rod. The rod extends into the upper cover and is fixedly connected to the diaphragm. The upper cover and lower housing are fixed together by a rivet ring. The periphery of the diaphragm forms a clamping seal when the upper cover and lower housing are fixed together. The lower end of the connecting rod is attracted to a magnet. The slider is placed inside the valve seat and slides up and down. The magnet is fixedly connected to the upper end of the slider. The lower end of the slider is connected to a sealing gasket that closes the valve port when the slider slides down to its final position. In the initial state, under the elastic action of the diaphragm, the lower end of the connecting rod presses against the magnet and the slider. The sealing gasket at the lower end of the slider presses against the valve port of the valve seat to form a seal, thus closing the inlet and outlet of the lower housing. When the connecting rod moves upward, the attracted end of the connecting rod drives the magnet and the slider upward, releasing the seal between the sealing gasket of the slider and the valve port of the valve seat, opening the inlet and outlet of the lower housing.

[0004] The upper end of the slider is fitted with a magnetic sleeve (also known as a round cover), and the magnet is embedded in the magnetic sleeve. The magnet and the magnetic sleeve are fixed to the upper end of the slider with screws. The assembly of the gas self-closing valve is done manually. However, the gas self-closing valve is relatively small in size, and the components used are also relatively small. Therefore, the assembly is difficult and slow, resulting in low production efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by proposing an assembly and fixing mechanism for a magnet and a round cover in a gas self-closing valve, thereby solving the problem of low production efficiency.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] The assembly and fixing mechanism of the magnet and the round cover in the gas self-closing valve includes a linear vibrator, a guide plate located on the top of the linear vibrator with the front and rear ends being the discharge end and the feed end, respectively, a clamp located in front of the guide plate, and a bracket located on one side of the linear vibrator. The bracket is characterized by having a material-grabbing component connected to it. The lower end of the material-grabbing component has a material-grabbing head that can be attracted by a magnet and can move up and down. The guide plate has a shoulder on the inner side of the discharge end. An electric screwdriver located directly above the clamp and capable of moving up and down is also connected to the bracket. The material-grabbing component can reciprocate along the bracket, causing the material-grabbing head to reciprocate between the clamp and the electric screwdriver and above the discharge end of the guide plate. The material-grabbing head has a clearance hole in the vertical direction through which the lower end of the electric screwdriver can pass.

[0008] Initially, the pick-up head is positioned between the clamp and the electric screwdriver. The valve body of the gas self-closing valve, which contains a slider, is positioned on the clamp. A linear vibrator, in conjunction with a guide plate, conveys the round cover. The magnet can be pre-installed inside the round cover or placed separately after the round cover moves to the discharge end of the guide plate. When the round cover moves to the discharge end of the guide plate and is blocked by the shoulder, the pick-up assembly moves relative to the support, causing the pick-up head to move above the round cover at the discharge end of the guide plate. Then, the pick-up head moves downward and contacts the magnet inside the round cover, forming an attraction. Afterward, the pick-up head moves upward and lifts the magnet and the round cover (the fit between the magnet and the round cover is relatively tight). Next, the component consisting of the magnet and the round cover is transported to the top of the fixture by the reset movement of the pick-up assembly. Then, the pick-up head moves down again and presses the component consisting of the magnet and the round cover against the upper end of the slider. Finally, a screw is inserted into the inner hole of the magnet through the clearance hole. Then, the electric screwdriver moves down and, in conjunction with the rotation of the electric screwdriver bit, tightens the screw, thereby fixing the magnet and the round cover onto the slider.

[0009] The above setup enables the automatic assembly and fixation of the magnet and the round cover into the valve body of the gas self-closing valve, significantly improving production efficiency. Furthermore, by providing a clearance hole through which the electric screwdriver bit passes, the issue of how to separate the feed head from the magnet afterward is eliminated. This is because once the magnet and the round cover are fixed to the slider, a further upward movement of the feed head will not lift the magnet.

[0010] In the assembly and fixing mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, the material taking component also includes a material taking sliding seat that is slidably arranged on the bracket in the front-back direction, a material taking cylinder fixedly connected to the material taking sliding seat, and a connector fixedly connected to the lower end of the piston rod of the material taking cylinder. The material taking head is fixedly connected to the lower end of the connector and the material taking head protrudes out of the side wall of the connector.

[0011] The material-grabbing sliding seat is used to enable the reciprocating translation of the material-grabbing assembly along the bracket, allowing the material-grabbing head to switch between the position between the clamp and the electric screwdriver and the position above the discharge end of the guide plate. The material-grabbing cylinder is used to move the material-grabbing head up and down. By fixing the material-grabbing head to the lower end of the connector and having the material-grabbing head protrude beyond the side wall of the connector, the reciprocating translation of the material-grabbing assembly along the bracket will not interfere with the electric screwdriver located directly above the clamp.

[0012] In the assembly and fixing mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, the feeding head includes a feeding part and a strip-shaped connecting part arranged on the left and right sides. One end of the connecting part is fixed to the lower side of the connecting head, and the other end of the connecting part is fixed to the upper side of the feeding part. The clearance hole is located in the feeding part.

[0013] The connecting part is strip-shaped and arranged along the left and right sides. One end of the connecting part is fixed to the lower side of the connector, and the other end of the connecting part is fixed to the upper side of the material taking part. In this way, the lower side of the connecting part and the side of the material taking part can form a clearance space, so that the material taking part can move down into the valve body without being restricted by the valve body opening of the gas self-closing valve, so as to cooperate with the electric screwdriver to complete the automatic assembly and fixation of the magnet and the round cover in the valve body.

[0014] In the above-mentioned gas self-closing valve, the assembly and fixing mechanism of the magnet and the round cover also includes a magnet storage seat located on the other side of the linear vibrator. A suction component is also connected to the bracket. The lower end of the suction component has a suction head that can be attracted by the magnet. The suction component can reciprocate along the bracket to make the suction head reciprocate above the magnet storage seat and above the discharge end of the guide plate. The suction head can move up and down, and the suction component also has a discharge component that can move downward relative to the suction head and remove the magnet attracted to the lower end of the suction head downward.

[0015] In practical use, the magnet is placed in the magnet storage base, while the round cover is fed into the guide plate by a vibratory feeder. Initially, the suction head is directly above the magnet storage base, and the take-up head is directly above the fixture. The suction head moves downward and contacts the magnet placed in the magnet storage base to form an adsorption. Then, the suction assembly moves horizontally, causing the suction head to move to the top of the round cover at the discharge end of the guide plate. The unloading component moves downward to remove the magnet adsorbed at the lower end of the suction head and press it into the round cover, achieving automatic assembly. Next, the take-up component removes the round cover containing the magnet from the guide plate and feeds it into the valve body of the gas self-closing valve mounted on the fixture. Finally, an electric screwdriver is used to complete the assembly and fixation of the magnet and the round cover in the valve body of the gas self-closing valve. Through the above settings, the assembly and fixation mechanism of the magnet and the round cover in this gas self-closing valve also has the function of automatically assembling the magnet into the round cover, further improving production efficiency.

[0016] In the assembly and fixing mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, the suction head is columnar, and the lower end of the suction head has a mating part. The mating part has a mating section one and a mating section two from top to bottom. The outer diameter of the mating section one gradually decreases from top to bottom, and the outer diameter of the mating section two is the same as the minimum outer diameter of the mating section one.

[0017] The shape of the mating part is such that it can fit perfectly with the inner hole on the magnet, so that the suction head can stably pick up the magnet and ensure that the magnet does not tilt, thus improving the reliability of automatically inserting the magnet into the round cover.

[0018] In the assembly and fixing mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, the suction assembly also includes a suction sliding seat slidably disposed on the bracket and a suction cylinder and a discharge cylinder both fixedly connected to the suction sliding seat. The suction head is fixedly connected to the lower end of the piston rod of the suction cylinder, and the discharge part is plate-shaped and sleeved outside the suction head. The discharge part is fixedly connected to the lower end of the piston rod of the discharge cylinder.

[0019] The suction slide seat enables the entire suction assembly to move horizontally on the support, while the suction cylinder enables the suction head to move vertically. After the suction head embeds the attracted magnet into the round cover located at the discharge end of the guide plate, the piston rod of the ejector cylinder extends downward and drives the ejector component downward. After the ejector component comes into contact with the magnet, its continued downward movement naturally pushes the magnet downward and separates it from the suction head. This design ensures that the magnet is accurately inserted into the round cover.

[0020] In the assembly and fixing mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, the magnet storage seat is a vertically arranged round tube, and a pusher component that is rod-shaped and can move up and down is provided inside the magnet storage seat.

[0021] Magnets are placed one by one into the magnet storage holder, where they will attract each other to form a string. During each assembly, the pusher pushes this string upwards, exposing the top magnet outside the upper end of the magnet storage holder. After the suction head picks up the magnet, the suction assembly moves it horizontally, and the force of the movement automatically separates the magnet from the other magnet located below it and attracted to it.

[0022] This design allows workers to insert multiple magnets at once, eliminating the need for them to insert a magnet for each assembly, thus improving production efficiency. Furthermore, the force exerted by the translating suction assembly automatically separates the magnet held at the bottom of the suction head from the magnet located below it. This eliminates the need for a separate magnet separator, allowing the assembly and fixing mechanism of the magnet and the round cover in this gas self-closing valve to automatically assemble the magnet into the round cover while maintaining a simple structure.

[0023] In the assembly and fixing mechanism of the magnet and the round cover in the above-mentioned gas self-closing valve, the upper port of the magnet storage seat is slightly higher than the guide plate.

[0024] The upper end of the magnetic storage base is slightly higher than the guide plate, which means that after the suction head moves horizontally from the upper end of the guide tube to above the discharge end of the guide plate, the magnet attracted to the lower end of the suction head is very close to the round cover. This also ensures that the stripper can accurately press the magnet into the round cover.

[0025] Compared with existing technologies, the assembly and fixing mechanism of the magnet and the round cover in this gas self-closing valve has the following advantages:

[0026] 1. By setting up the material handling components, material handling head and electric screwdriver, the function of automatically assembling the magnet into the round cover is realized, which improves production efficiency;

[0027] 2. By setting up the suction component, suction head and magnet storage base, the function of automatically assembling the magnet into the round cover is realized, which further improves production efficiency. Attached Figure Description

Detailed Implementation

[0039] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0040] like Figures 1-5As shown, the assembly and fixing mechanism of the magnet and the round cover in the gas self-closing valve includes a frame 1, a worktable 2 set on the frame 1, a linear vibrator 3 fixed on the frame 1, and a clamp 4 located near the edge of the worktable 2. The linear vibrator 3 has a guide plate 5 with a discharge end and a feed end at its front and rear ends, respectively. The guide plate 5 has a feeding groove arranged along its length direction, and a shoulder 5a is provided on the inner side of the discharge end port of the guide plate 5. The clamp 4 is located in front of the guide plate 5 and has a positioning cavity penetrating its top surface, and the positioning cavity penetrates the clamp 4 in the front-rear direction. It also includes a bracket 6 fixed on the frame 1 and located on one side of the linear vibrator 3. A material picking component 7 is connected to the bracket 6. The lower end of the material picking component 7 has a material picking head 8 that can be attracted by the magnet 36 and can move up and down. An electric screwdriver 9, located directly above the clamp 4 and capable of vertical movement, is also connected to the bracket 6. The material-taking assembly 7 can reciprocate along the bracket 6, causing the material-taking head 8 to reciprocate between the clamp 4 and the electric screwdriver 9 and above the discharge end of the guide plate 5. The material-taking head 8 has a clearance hole 8a1 in the vertical direction, allowing the lower end of the electric screwdriver 9 to pass through. In this embodiment, the frame 1 is fixedly connected to a mounting base 10, and the bracket 6 and the linear vibrator 3 are both fixedly connected to the mounting base 10.

[0041] Among them, such as Figures 2-5As shown, the material handling assembly 7 also includes a material handling sliding seat 11 slidably disposed on the bracket 6 in the front-back direction, a material handling cylinder 12 fixedly connected to the material handling sliding seat 11, and a connector 13 fixedly connected to the lower end of the piston rod of the material handling cylinder 12. The material handling head 8 is fixedly connected to the lower end of the connector 13 and protrudes from the side wall of the connector 13. The material handling sliding seat 11 is used to realize the reciprocating translation of the material handling assembly 7 along the bracket 6 so as to realize the switching of the position of the material handling head 8 between the clamp 4 and the electric screwdriver 9 and the position above the discharge end of the guide plate 5. The material handling cylinder 12 is used to realize the up-down movement of the material handling head 8. By fixing the material handling head 8 to the lower end of the connector 13 and making the material handling head 8 protrude from the side wall of the connector 13, the reciprocating translation of the material handling assembly 7 along the bracket 6 will not interfere with the electric screwdriver 9 located directly above the clamp 4. The support 6 has a material-picking slide rail 14 arranged along the front and back. The material-picking sliding seat 11 is slidably connected to the material-picking slide rail 14. The support 6 is also provided with a material-picking translation cylinder 15 with a piston rod arranged along the front and back. The material-picking sliding seat 11 is fixedly connected to the end of the piston rod of the material-picking translation cylinder 15. The movement of the piston rod of the material-picking translation cylinder 15 can drive the material-picking sliding seat 11 to move along the material-picking slide rail 14, thereby driving the material-picking sliding seat 11 to move back and forth, which is the translation of the entire material-picking assembly 7 in the front and back direction. The material-picking head 8 includes a material-picking part 8a and a strip-shaped connecting part 8b arranged in the left and right direction. The material-picking part 8a is L-shaped. One end of the connecting part 8b is fixedly connected to the lower part of the connecting head 13, and the other end of the connecting part 8b is fixedly connected to the upper part of the material-picking part 8a. The clearance hole 8a1 is located on the horizontal part of the material-picking part 8a. The connecting part 8b is strip-shaped and arranged along the left and right sides. One end of the connecting part 8b is fixed to the lower side of the connecting head 13, and the other end of the connecting part 8b is fixed to the upper side of the material taking part 8a. In this way, the lower side of the connecting part 8b and the side of the material taking part 8a can form a clearance space, so that the material taking part 8a can move down into the valve body without being restricted by the valve body opening of the gas self-closing valve, so as to cooperate with the electric screwdriver 9 to complete the automatic assembly and fixation of the magnet 36 and the round cover 35 in the valve body. The material taking head 8 is an iron part, and the material taking head 8 is integrally fixed to the connecting head 13. The bracket 6 is also provided with a vertical sliding seat 16, and a movable plate 17 that can move up and down relative to the vertical sliding seat 16 is provided on the vertical sliding seat 16. The electric screwdriver 9 is fixedly connected to the movable plate 17. A screw feed head 18 is fixed directly below the electric screwdriver 9 on the vertical sliding seat 16. The lower end of the screw feed head 18 has a hole alignment nozzle 18a, and the outer diameter of the hole alignment nozzle 18a is smaller than the diameter of the clearance hole 8a1. Specifically, the screw feed head 18 is prior art, and can be directly referred to as the automatic screw driving device of patent application number 202221685683.8 or the screw tube holding device and automatic screw driving machine of patent application number 201010298057.6.In this embodiment, the bracket 6 includes a vertically arranged base plate 6a, a connecting plate 6b fixed to the upper end of the base plate 6a, a connecting plate 6c parallel to the connecting plate 6b, and a connecting plate 6d that connects the connecting plate 6b and the connecting plate 6c. The lower end of the base plate 6a is fixed to the mounting base 10. The material picking slide rail 14 is provided on the connecting plate 6b. A first driving cylinder 19 for driving the vertical sliding seat 16 to move up and down is fixed on the connecting plate 6c. A second driving cylinder 20 for driving the movable plate 17 to move up and down is fixed on the vertical sliding seat 16.

[0042] Furthermore, such as Figure 6 , Figure 7 and Figure 8As shown, the assembly and fixing mechanism of the magnet and the round cover in this gas self-closing valve also includes a magnet storage seat 21 fixed on the frame 1 and located on the other side of the linear vibrator 3. A suction assembly 22 is also connected to the support 6. The lower end of the suction assembly 22 has a suction head 23 that can be attracted by the magnet 36. The suction assembly 22 can reciprocate along the support 6 so that the suction head 23 reciprocates above the magnet storage seat 21 and above the discharge end of the guide plate 5. The suction head 23 can move up and down, and the suction assembly 22 also has a discharge part 24 that can move downward relative to the suction head 23 and remove the magnet 36 attracted to the lower end of the suction head 23 downward. The suction head 23 is made of iron and is cylindrical. The lower end of the suction head 23 has a mating part 23a. The mating part 23a has a first mating section 23a1 and a second mating section 23a2 from top to bottom. The outer diameter of the first mating section 23a1 gradually decreases from top to bottom, and the outer diameter of the second mating section 23a2 is the same as the minimum outer diameter of the first mating section 23a1. This shape of the mating part 23a can fit into the inner hole on the magnet 36, so that the suction head 23 can stably pick up the magnet 36 and ensure that the magnet 36 will not be tilted, thus improving the reliability of automatically inserting the magnet 36 into the round cover 35. The suction assembly 22 also includes a suction sliding seat 25 slidably mounted on the bracket 6, and a suction cylinder 26 and a discharge cylinder 27 both fixedly connected to the suction sliding seat 25. The suction head 23 is fixedly connected to the lower end of the piston rod of the suction cylinder 26. The discharge component 24 is plate-shaped and sleeved on the outside of the suction head 23. The discharge component 24 is fixedly connected to the lower end of the piston rod of the discharge cylinder 27. There are two discharge cylinders 27, which are located on both sides of the suction cylinder 26. Specifically, the sliding direction of the suction sliding seat 25 is left and right. The bracket 6 has a suction slide rail 28 arranged along the left and right sides. The suction sliding seat 25 is slidably connected to the suction slide rail 28. The bracket 6 is also provided with a suction translation cylinder 29 with a piston rod arranged along the left and right sides. The suction sliding seat 25 is fixedly connected to the end of the piston rod of the suction translation cylinder 29. The movement of the piston rod of the suction translation cylinder 29 can drive the suction sliding seat 25 to move along the suction slide rail 28, thereby driving the suction sliding seat 25 to move left and right, which is the translation of the entire suction assembly 22 in the left and right direction. In this embodiment, the bracket 6 also includes a connecting plate four 6e fixedly connected to the connecting plate one 6b. The connecting plate four 6e is parallel to the connecting plate three 6d and is located behind the connecting plate three 6d. The suction slide rail 28 is provided on the connecting plate four 6e.

[0043] like Figure 6 , Figure 7 and Figure 9As shown, the magnet storage base 21 is a vertically arranged cylindrical tube. The magnet storage base 21 is preferably made of a material that will not be attracted by the magnet 36, such as aluminum alloy. Inside the magnet storage base 21 is a rod-shaped pusher 30 that can move up and down. The upper end of the magnet storage base 21 is slightly higher than the guide plate 5. An electric push rod 31 is fixedly connected inside the frame 1, and the pusher 30 is the piston rod of the electric push rod 31. A mounting ring 32 is fixedly connected to the upper end of the magnet storage base 21. The mounting ring 32 is specifically an open ring. In practice, a screw can be installed at the opening of the mounting ring 32. After the mounting ring 32 is fitted onto the upper end of the magnet storage base 21, the screw is tightened to close the opening and fix the mounting ring 32 to the magnet storage base 21. The mounting ring 32 is equipped with a through-beam fiber optic sensor 33. The upper side of the mounting ring 32 has oppositely arranged protrusions 32a. The two probes of the through-beam fiber optic sensor 33 are respectively fixed on the two protrusions 32a. The two protrusions 32a are specifically distributed on the front and rear sides of the upper port of the magnet storage base 21.

[0044] In practice, such as Figure 1 As shown, the workbench 2 is a turntable. The feed end of the guide plate 5 is connected to the vibratory feeder 34, and the vibratory feeder 34 sequentially feeds the round covers 35 onto the guide plate 5. Magnets 36 are sequentially placed in the magnet storage seat 21, and the magnets 36 attract each other to form a string. The valve body of the gas self-closing valve with a slider inside is installed and positioned on the fixture 4. The state during use is as follows. Figure 10 As shown. In the initial state, the suction head 23 is located directly above the magnet storage base 21, and the picking head 8 is located above the clamp 4. The pusher 30 moves the entire string of magnets 36 upward so that the uppermost magnet 36 is exposed outside the upper port of the magnet storage base 21. After the presence of the magnet 36 is detected by the through-beam fiber optic sensor 33, the pusher 30 stops moving and the piston rod of the suction cylinder 26 extends downward, so that the mating part 23a of the suction head 23 is inserted into the inner hole of the magnet 36 and forms an adsorption. Next, the piston rod of the suction translation cylinder 29 extends and drives the suction sliding seat 25 to translate, so that the suction head 23 is translated directly above the discharge end of the guide plate 5. During this process, the force of translation separates the magnet 36 adsorbed at the lower end of the suction head 23 from the magnet 36 located below it. After the suction sliding seat 25 is moved into position so that the magnet 36 adsorbed at the lower end of the suction head 23 is directly above the round cover 35 at the discharge end of the guide plate 5, the piston rod of the unloading cylinder 27 extends downward and drives the unloading component 24 to move downward. The unloading component 24 removes the magnet 36 adsorbed at the lower end of the suction component and presses it into the round cover 35 to achieve automatic installation.

[0045] Next, the suction sliding seat 25 returns to its initial position, and then the material-picking sliding seat 11 is moved by the material-picking translation cylinder 15, so that the material-picking head 8 moves from above the clamp 4 to directly above the round cover 35 at the discharge end of the guide plate 5. After that, the piston rod of the material-picking cylinder 12 extends downward, so that the material-picking part 8a of the material-picking head 8 contacts the magnet 36 installed in the round cover 35 at the discharge end of the guide plate 5 and forms an adsorption. The magnet 36, along with the round cover 35, is removed from the guide plate 5 by the upward retraction of the piston rod of the material-picking cylinder 12 (the fit between the magnet 36 and the round cover 35 is relatively tight). Then, the material handling translation cylinder 15 drives the sliding seat to reset, causing the material handling head 8 to move back above the clamp 4. The piston rod of the material handling cylinder 12 then extends downwards, causing the material handling part 8a of the material handling head 8 to enter the valve body of the gas self-closing valve, so that the assembly of the magnet 36 and the round cover 35 abuts against the upper end of the slider. Finally, the first drive cylinder 19 drives the vertical sliding seat 16 to move downwards, causing the alignment nozzle 18a of the screw feed head 18 to pass through the clearance hole 8a1 of the material handling head 8 and abut against the upper end of the magnet 36. Then, the second drive cylinder 20 drives the movable plate 17 to move downwards, causing the electric screwdriver 9 to pass through the screw feed head 18 and, in conjunction with the rotation of the screwdriver bit, tighten the screw inside the screw feed head 18 onto the slider, thereby fixing the magnet 36, the round cover 35, and the slider together.

[0046] With the above settings, the assembly and fixing mechanism of the magnet and the round cover in this gas self-closing valve has the functions of automatically assembling the magnet 36 into the round cover 35, and automatically assembling the magnet 36 and the round cover 35 into the valve body of the gas self-closing valve and fixing them, which greatly improves production efficiency.

[0047] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
