Description

Technical Field

[0001] This invention relates to the field of gas stove technology, and in particular to a gas pipeline assembly that operates stably. Background Technology

[0002] The design of gas pipeline components involves the safe and efficient transportation of gas, ensuring the safety and convenience of users in daily gas use; and low-pressure pipelines are usually used, with pressure ratings generally between 2000Pa and 2800Pa, to ensure that natural gas does not leak during transportation and maintains appropriate pressure.

[0003] Currently, existing gas stove pipelines consist of a single gas pipe connecting one gas inlet device and multiple ignition devices. The pipeline is interconnected in the middle. When one of the ignition devices is activated, the large internal cavity of the pipeline can easily lead to unstable gas pressure, resulting in flameout or flame spikes. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings in the prior art, the problem to be solved by the present invention is to provide a novel gas stove pipe assembly that can separate each ignition device and its corresponding gas supply chamber for ignition.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows: Specifically, a stable gas pipeline assembly is provided, including a T-shaped tee pipe. The tee pipe includes a horizontal pipe and a vertical pipe extending through its middle and lower part. Two inclined pipes with openings opposite each other, forming a barrel-shaped structure, are fixed to the left and right ends of the tee pipe. The tee pipe and the two inclined pipes constitute a gas supply chamber. The upper structures of the two inclined pipes are identical and symmetrical. An outlet and an inlet are respectively opened on the top of the outer wall of each inclined pipe. The inlet is used to connect to a natural gas pipeline or a liquefied gas tank, and the outlet is used to connect to a combustion module. A middle baffle extending vertically to the bottom of the vertical pipe is fixed to the middle of the top inner wall of the horizontal pipe of the tee pipe. A retaining spring is fixed to both sides of the middle baffle. A sealing abutment is fixed to the far end of each of the two retaining springs, and the sealing abutments are slidably connected to the left and right ends of the tee pipe near the inclined pipes. A limiting block is fixed to the top inner wall of the inclined pipe near the tee pipe to block the sealing abutment.

[0006] A further feature of this invention is that connecting pipe column one and connecting pipe column two are welded to the air outlet and air inlet, respectively. A combustion module is provided at the top of connecting pipe column one, and the combustion module includes an air outlet pipe two fixed to the top of connecting pipe column one. The air outlet pipe two has an arc-shaped structure, and an ignition valve is fixedly connected to the end of the air outlet pipe two away from the oblique pipe. An ignition device is provided on the side of the ignition valve. An air inlet pipe one and a pressure reducing valve are fixed to the top of each of the connecting pipe columns two. This arrangement makes the overall structure compact, prevents the cross-flow of pipes from causing mutual interference, and improves the overall safety performance.

[0007] A further feature of the present invention is that the end of the oblique tube near the tee tube is lower than the other end, and the bottom of the horizontal tube of the tee tube is provided with chip removal holes near the junction of the two ends. External threaded tubes are sealed and welded into the chip removal holes, and material receiving boxes are screwed to the bottom ends of the two external threaded tubes. Notches are provided on the side of the two sealing abutments that are far apart from each other near the top of the external threaded tubes.

[0008] A further feature of this invention is that a notch is pre-reserved in the middle of the bottom end of the intermediate baffle, and fixed pulleys are provided on both the left and right sides of the intermediate baffle near the notch. Anti-slip grooves are pre-reserved on the outer circumference of the fixed pulleys. One-third of the wheel surface of the fixed pulley is inserted into the notch, and the two fixed pulleys are symmetrical about the intermediate baffle. A fixed frame with a downward-opening rectangular barrel structure is fitted and fixed to the bottom end of the vertical pipe of the tee pipe. Electric push rods are fixed to the inner walls of both the left and right sides of the fixed frame, and the extension rods of the electric push rods are located at the end away from the tee pipe. Pull ropes are fixed to the ends of the extension rods of both electric push rods, and the pull ropes pass around the fixed pulleys on the same side and through the clamping springs on the same side, fixing them to the ends of the corresponding sealing posts. A ring is provided at the end of the sealing post near the oblique pipe. The three-way pipe has a shaped groove, and multiple sealing rings are fitted inside the groove. Near the two ends of the horizontal pipe of the three-way pipe, two air supply pipes, one and two, are respectively inserted and are centrally symmetrically distributed. One-way valves in opposite directions are respectively installed in the middle of air supply pipes one and two. A docking hole is provided on one end of the three-way pipe near the oblique pipe and on the other oblique pipe. Both ends of air supply pipe one are inserted into docking hole one. The docking hole one at the end of air supply pipe one near the three-way pipe is located between the multiple sealing rings and the intermediate baffle, ensuring that gas does not cross the multiple sealing rings and enter air supply pipe one. A docking hole two is also provided on one end of the three-way pipe near the oblique pipe and on the other oblique pipe. The docking hole two is centrally symmetrically distributed with docking hole one. Both ends of air supply pipe two are inserted into docking hole two. With the installation of air supply pipe one and air supply pipe two, in conjunction with the installation of electric push rod two, when the combustion module needs to start high-fire combustion, the electric push rod two on the opposite side can be opened. At this time, the sealing column and its outer wall multi-layer sealing ring will move towards the middle, thereby exposing the air inlet of air supply pipe one or air supply pipe two to supplement the air supply chamber of the combustion module, thereby stabilizing and increasing the firepower.

[0009] A further feature of this invention is that the top of the ignition valve has a valve torsion rod connected to the valve core, and the top of the ignition valve has an annular platform. A C-shaped slide is fixed to the outer circumference of the annular platform. A return spring is fixed to the top of the annular platform, and a knob is fixed to the top of the return spring. A spring contact piece is fixed to the lower surface of the knob. When the knob is pressed down, the spring contact piece will contact the C-shaped slide, thus activating the control switch of the ignition device. At this time, the ignition device begins to generate a pulsed electric spark. Simultaneously, the knob is rotated to drive the valve torsion rod and the valve core to rotate. At this time, the burner in the combustion module begins to release gas. The spring contact piece continues to contact the C-shaped slide until the injected gas is ignited, at which point the pressure on the knob can be released.

[0010] A further feature of this invention is that a fixed support is fixed to the front of the fixed frame, and a delay switch is provided on both the left and right sides of the fixed support. The delay switch includes a starting circuit and a control circuit. The control circuit is used to control the movement of the corresponding electric push rod two. That is, when one of the combustion modules outputs a signal that needs to increase the intake air volume, the "starting circuit is turned on" and the signal is transmitted to the delay switch. After the delay switch is powered on, it will start within a set time, such as 5 seconds. That is, after 5 seconds, the extension rod of the corresponding electric push rod two is controlled to extend to replenish the gas.

[0011] A further feature of this invention is that a groove is formed in the middle of the upper surface of the C-shaped slider, and a magnetic metal contact is engaged in the groove. The magnetic metal contact and the spring contact piece are connected in series in the starting circuit. By setting the magnetic metal contact in the middle (when the ignition valve is fully open), when the spring contact piece moves to the magnetic metal contact during use, it will be attracted, thus keeping the starting circuit connected for a long time. Immediately afterwards, the corresponding delay switch is also activated, and gas is replenished after a set number of seconds. The delay switch can prevent accidental activation that could lead to a rapid gas supply and cause the fire to spread rapidly, catching people off guard. This design provides reaction time and improves the safety of the equipment.

[0012] A further feature of this invention is that the time-delay switch includes an L-shaped oil tank with an overall L-shaped internal cavity. The vertical side of the L-shaped oil tank is fixed to the side of the fixed support, and a piston barrel with its opening away from the fixed support is fixed above the horizontal plate of the L-shaped oil tank. A damping tube for connecting the inner cavities of the piston barrel and the vertical side wall of the L-shaped oil tank is fixed between the bottom of the piston barrel and the vertical side wall of the L-shaped oil tank. A reset spring is fixed to the bottom of the piston barrel, and a piston rod is fixed to the end of the reset spring away from the bottom. A sealing ring is fitted around the outer circumference of the piston rod, and a push rod is fixed to the end of the piston rod away from the reset spring. A second terminal is welded to the outer wall of the push rod. A first terminal is provided on the upper surface of the horizontal plate of the L-shaped oil tank near the opening of the piston barrel. Through the damping tube between the L-shaped oil tank and the piston barrel, when the time-delay switch responds as a whole, due to the presence of the damping tube, the piston rod needs a certain period of time to bring the end of the push rod to the surface of the first terminal, thereby connecting the control circuit.

[0013] A further feature of this invention is that an electric push rod is fixed to the top of the vertical plate of the L-shaped oil tank, and a magnetic ring is fixed to the end of the extension rod of the electric push rod. The magnetic ring is slidably fitted onto the outer wall of the piston barrel. Three centrally symmetrical roller frames are provided on both the front and rear sides of the magnetic ring. Rollers that are attached to the outer wall of the piston barrel are provided on each roller frame. Permanent magnets are fixed near the circumferential edge on the side of the piston rod away from the return spring. The end of the permanent magnet near the barrel wall of the piston barrel is attracted to the magnetic ring. The control switch of the electric push rod is connected in series in the starting circuit. That is, after the starting circuit is turned on, the electric push rod controls its extension rod to extend, which then drives the magnetic ring to slowly move towards the opening of the piston barrel. Under the action of magnetic attraction and the action of the damping tube, it will eventually drive the push rod and the terminal block to contact, and then connect the control circuit to replenish the gas.

[0014] A further feature of this invention is that the piston barrel is made of an insulating and wear-resistant material, ensuring that magnetism can penetrate the piston barrel and pull the piston rod to move.

[0015] The beneficial effects of this invention are as follows: 1. By using a tee pipe between two oblique pipes, along with a sealing abutment, the air supply chamber can be separated. Since the volume of the separated air supply chamber is smaller, the intake air pressure is more stable, thus ensuring the quality of ignition.

[0016] 2. By setting two inclined pipes and using a receiving box for receiving materials, impurities generated in the air supply chamber can be collected, thereby reducing the phenomenon of impurities clogging the narrow air passage in the traditional air intake process, ensuring smooth air supply, and making regular chip removal more convenient.

[0017] 3. With the installation of air supply pipe one and air supply pipe two, and the setting of electric push rod two, when the combustion module needs to start high-fire combustion, the electric push rod two on the opposite side can be opened. At this time, the sealing column and its outer wall multi-layer sealing ring will move to the middle, thereby exposing the air inlet of air supply pipe one or air supply pipe two to supplement the air supply chamber of the combustion module, thereby stabilizing and increasing the firepower.

[0018] 4. By setting a time-delay switch, it is possible to prevent accidental activation that could lead to a rapid gas supply and cause the fire to spread quickly, catching people off guard. This setting provides reaction time and improves the safety of the equipment. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In this embodiment, refer to Figures 1-11 This solution provides a stable gas pipeline assembly, which includes a T-shaped tee pipe 1. The tee pipe 1 includes a horizontal pipe and a vertical pipe passing through its middle and lower part. Two inclined pipes 8 with openings opposite each other and having a barrel-like structure are fixed to the left and right ends of the tee pipe 1. The tee pipe 1 and the two inclined pipes 8 constitute a gas supply chamber. The structures above the two inclined pipes 8 are identical and symmetrical. An outlet 801 and an inlet 802 are respectively opened on the top of the outer wall of the inclined pipe 8. The inlet 802 is used to connect to a natural gas pipeline or a liquefied gas tank, and the outlet 801 is used to connect to a combustion module. A [missing information - likely a component or part] is fixed in the middle of the inner wall of the top of the horizontal pipe of the tee pipe 1. A middle baffle 19 extends vertically to the bottom end of the vertical pipe, and a retaining spring 21 is fixed on both sides of the middle baffle 19. A sealing abutment 22 is fixed at the far end of the two retaining springs 21. The sealing abutment 22 is slidably connected to the left and right ends of the three-way pipe 1 near the oblique pipe 8. A limiting block 23 is fixed on the inner wall of the oblique pipe 8 near the three-way pipe 1 to block the sealing abutment 22. By setting the three-way pipe 1 between the two oblique pipes 8, and with the setting of the sealing abutment 22, the air supply chamber can be separated. Since the volume of the air supply chamber after separation is smaller, the intake air pressure is more stable, thereby ensuring the quality of ignition.

[0023] In this invention, connecting pipe column one 14 and connecting pipe column two 15 are welded to the air outlet 801 and air inlet 802, respectively. A combustion module is provided at the top of the connecting pipe column one 14, and the combustion module includes an air outlet pipe two 6 fixed to the top of the connecting pipe column one 14. The air outlet pipe two 6 has an arc-shaped structure, and an ignition valve 5 is fixedly connected to the end of the air outlet pipe two 6 away from the oblique pipe 8. An ignition device 3 is provided on the side of the ignition valve 5. An air inlet pipe one 7 and a pressure reducing valve are fixed to the top of the connecting pipe column two 15. With this arrangement, the overall structure is compact, preventing the cross-flow of pipes from causing mutual interference and improving the overall safety performance.

[0024] Reference Figure 2 and Figure 4 The inclined pipe 8 is lower at one end than the other end of the tee pipe 1, and the bottom of the horizontal pipe of the tee pipe 1 is provided with chip removal holes near the junction of the two ends. The chip removal holes are sealed with external threaded pipes 27, and the bottom ends of the two external threaded pipes 27 are screwed with receiving boxes 13. The two sealing posts 22 are far apart on the side near the top of the external threaded pipes 27, and notches 2201 are provided. By setting two inclined pipes 8, and in conjunction with the receiving boxes 13 for receiving materials, impurities generated in the air supply chamber can be collected, thereby reducing the phenomenon of impurities blocking the narrow air passage in the traditional air intake process, ensuring smooth air supply, and making regular chip removal more convenient.

[0025] Reference Figure 2 , Figure 4 , Figure 7The middle baffle 19 has a notch at the bottom center, and fixed pulleys 20 are provided on both the left and right sides of the middle baffle 19 near the notch. The outer circumference of the fixed pulleys 20 has anti-slip grooves. One-third of the wheel surface of the fixed pulley 20 is inserted into the notch, and the two fixed pulleys 20 are symmetrical about the middle baffle 19. The bottom of the vertical pipe of the tee pipe 1 is fitted with a fixed frame 12 with a downward-opening rectangular barrel structure. Electric push rods 18 are fixed on the inner walls of both the left and right sides of the fixed frame 12, and the extension rods of the electric push rods 18 are located at the far end. At one end of the three-way pipe 1, the ends of the extension rods of the two electric push rods 18 are each fixed with a pull rope 24. The pull rope 24 passes over the fixed pulley 20 on the same side and through the clamping spring 21 on the same side, and is fixed to the end of the corresponding sealing post 22. The sealing post 22 has an annular groove at the end near the oblique pipe 8, and a multi-layer sealing ring 2202 is sleeved in the annular groove. At the top of the horizontal pipe of the three-way pipe 1, near both ends, air supply pipe 1 2 and air supply pipe 2 17 are respectively inserted, which are centrally symmetrically distributed. The middle of air supply pipe 1 2 and air supply pipe 2 17 are respectively provided with A one-way valve 16 with opposite directions is provided. A docking hole 25 is provided at one end of the three-way pipe 1 near the oblique passage pipe 8 and on the other oblique passage pipe 8. Both ends of the air supply pipe 2 are inserted into the docking hole 25. The docking hole 25 at the end of the air supply pipe 2 near the three-way pipe 1 is located between the multi-layer sealing ring 2202 and the intermediate baffle 19, ensuring that gas does not cross the multi-layer sealing ring 2202 and enter the air supply pipe 2. A second docking hole 26 is also provided at one end of the three-way pipe 1 near the oblique passage pipe 8 and on the other oblique passage pipe 8. The second docking hole 26 is connected to the... The connection holes 25 are centrally symmetrically distributed. The two ends of the air supply pipe 17 are respectively inserted into the connection hole 26. With the air supply pipe 2 and air supply pipe 17, and the electric push rod 18, when the combustion module needs to start high-fire combustion, the electric push rod 18 on the opposite side can be opened. At this time, the sealing post 22 and its outer wall multi-layer sealing ring 2202 will move towards the middle, thus exposing the air inlet of the air supply pipe 2 or the air supply pipe 17 to supplement the air supply chamber of the combustion module, thereby stabilizing and increasing the firepower.

[0026] Reference Figure 4 , Figure 5 and Figure 11The top of the ignition valve 5 has a valve torsion rod 501 that is connected to the valve core, and the top of the ignition valve 5 has an annular platform. A C-shaped slide plate 29 is fixed on the outer circumference of the annular platform. A return spring 31 is fixed on the top of the annular platform. A knob 4 is fixed on the top of the return spring 31. A spring contact piece 28 is fixed on the lower surface of the knob 4. When the knob 4 is pressed down, the spring contact piece 28 will contact the C-shaped slide plate 29, which will turn on the control switch of the ignition device 3. At this time, the ignition device 3 will start to generate a pulse electric spark. At the same time, the knob 4 will be rotated to drive the valve torsion rod 501 and the valve core to rotate. At this time, the burner in the combustion module will start to release gas. The spring contact piece 28 will continue to contact the C-shaped slide plate 29 until the gas is ignited. Then the pressure on the knob 4 can be removed.

[0027] Reference Figure 4 and Figure 5 The fixed bracket 10 is fixed on the front of the fixed frame 12, and a delay switch 9 is provided on both the left and right sides of the fixed bracket 10. The delay switch 9 includes a starting circuit and a control circuit. The control circuit is used to control the movement of the corresponding electric push rod 18. That is, when one of the combustion modules outputs a signal that needs to increase the intake air volume, the "starting circuit is turned on" and the signal is transmitted to the delay switch 9. After the delay switch 9 is powered on, it will start within a set time, such as 5 seconds. That is, after 5 seconds, it controls the extension rod of the corresponding electric push rod 18 to extend and replenish the gas.

[0028] Reference Figure 11 A groove is provided in the middle of the upper surface of the C-shaped slider 29, and a magnetic metal contact 30 is engaged in the groove. The magnetic metal contact 30 and the spring contact piece 28 are connected in series in the starting circuit. By setting the magnetic metal contact 30 in the middle (i.e., when the ignition valve 5 is fully open), when the spring contact piece 28 moves to the magnetic metal contact 30, it will be attracted, and the starting circuit will be connected for a long time. Then, the corresponding delay switch 9 is also activated, and gas is replenished after a set number of seconds. The delay switch 9 can prevent the rapid supply of gas due to accidental activation, which could cause the fire to spread rapidly and catch people off guard. This setting can give people reaction time and improve the safety of the equipment.

[0029] Reference Figures 8-10The delay switch 9 also includes an L-shaped oil tank 901 with an overall L-shaped structure and an internal cavity. The vertical side of the L-shaped oil tank 901 is fixed to the side of the fixed support 10, and a piston barrel 903 with its opening away from the fixed support 10 is fixed above the horizontal plate of the L-shaped oil tank 901. A damping tube 904 for connecting the inner cavities of the piston barrel 903 and the vertical side wall of the L-shaped oil tank 901 is fixed between the bottom of the piston barrel 903 and the vertical side wall of the L-shaped oil tank 901. A reset spring 910 is fixed to the bottom of the piston barrel 903, and a piston column 909 is fixed to the end of the reset spring 910 away from the bottom of the barrel. The outer circumference of the piston column 909 is sleeved with... A sealing ring is attached, and a push rod 906 is fixed to the end of the piston rod 909 away from the reset spring 910. A second terminal is welded to the outer wall of the push rod 906. A first terminal 907 is provided on the horizontal plate surface of the L-shaped oil tank 901 near the opening of the piston barrel 903. Through the damping tube 904 provided between the L-shaped oil tank 901 and the piston barrel 903, when the delay switch 9 responds as a whole, due to the presence of the damping tube 904, the piston rod 909 needs a certain period of time to bring the end of the push rod 906 to the surface of the first terminal 907, thereby connecting the control circuit.

[0030] Reference Figures 8-10 An electric push rod 11 is fixed to the top of the vertical plate of the L-shaped oil tank 901, and a magnetic ring 902 is fixed to the end of the extension rod of the electric push rod 11. The magnetic ring 902 is slidably sleeved on the outer wall of the piston barrel 903. Three centrally symmetrical roller frames 905 are provided on both the front and rear sides of the magnetic ring 902. Rollers that are attached to the outer wall of the piston barrel 903 are provided on each roller frame 905. Permanent magnets are fixed on the side of the piston rod 909 away from the return spring 910 near the circumferential edge. Both the permanent magnet 908 and the end of the permanent magnet 908 near the wall of the piston barrel 903 are attracted to the magnetic ring 902. The control switch of the electric push rod 11 is connected in series in the starting circuit. After the starting circuit is turned on, the electric push rod 11 controls its extension rod to extend, which in turn drives the magnetic ring 902 to slowly move towards the opening of the piston barrel 903. Under the action of magnetic attraction and the action of the damping tube 904, it will eventually drive the push rod 906 to contact the terminal 907, and then connect the control circuit to replenish air.

[0031] In this invention, the piston barrel 903 is made of an insulating and wear-resistant material to ensure that magnetism can penetrate the piston barrel 903 and move the piston rod 909. Working principle: When using this device, if one of the combustion modules needs to be started, first press down the knob 4 to make the spring contact piece 28 contact with the C-shaped slide piece 29, which turns on the control switch of the ignition device 3. At this time, the ignition device 3 starts to generate pulse electric spark. At the same time, rotate the knob 4 to make the valve torsion rod 501 and the valve core rotate. At this time, the burner in the combustion module starts to release gas. The spring contact piece 28 continues to contact the C-shaped slide piece 29 until the gas is ignited. Then the pressure on the knob 4 can be released. When the combustion module needs to start high-fire combustion, turn knob 4 to the maximum position, that is, the spring contact piece 28 moves above the magnetic metal contact 30 and is attracted, which will then connect the start-up circuit for a long time. Then, the corresponding delay switch 9 is also activated, which opens the electric push rod 18 on the opposite side. At this time, the sealing post 22 and its outer wall multi-layer sealing ring 2202 will move towards the middle, thus exposing the air inlet of the air supply pipe 1 2 or the air supply pipe 2 17 to replenish the air supply chamber of the combustion module.
