Description

Technical Field

[0001] This utility model relates to the field of valve device technology, specifically a gas valve device. Background Technology

[0002] A gas valve is a type of valve controlled by pneumatic principles. It is mainly used to control the flow of fluids. The pneumatic valve uses compressed air to drive multiple sets of combined pneumatic pistons in the actuator, which transmit force to the crossbeam and the inner curved track, driving the hollow main shaft to rotate. By changing the inlet and outlet positions, the rotation direction of the main shaft can be changed, thereby controlling the opening and closing of the valve. Traditional gas valves are mostly single-inlet valves. When it is necessary to change to other gas supply, the pipeline needs to be disconnected and connected to other gas pipelines, which is relatively cumbersome. In order to improve this situation, a gas valve device is proposed.

[0003] As disclosed in the patent announcement number CN221857539U, a gas valve device includes a valve nozzle, a transmission frame, a rotating core, a housing, and a drive motor. The valve nozzle is connected to the housing. The transmission frame and the rotating core are disposed inside the housing. The housing has an exhaust port. The output end of the drive motor passes through the exhaust port and is connected to one end of the rotating core. The transmission frame has a track protrusion and a plug. The rotating core has a running track groove with a wavy groove. The track protrusion slides within the running track groove. The valve nozzle has an air inlet and an air filling port. The plug and the air inlet are disposed on the same axis. There is a gap between the transmission frame and the outer wall. A compression spring connected to the transmission frame is disposed inside the housing.

[0004] Although it achieves low noise during operation, integrates inflation and deflation functions, reduces the number of valves by half compared to electromagnetic coil pressure-holding valves, and eliminates the noise and heat generation problems of electromagnetic valves, it is less affected by temperature and has higher reliability compared to shape memory alloy wire control valves.

[0005] However, this does not solve the problem that existing valve devices are not conducive to convenient and flexible adjustment of different input gases during use, nor to elastic check valves for discharged gases, thus affecting the flexibility of use. Utility Model Content

[0006] The purpose of this utility model is to provide a gas valve device to solve the problems mentioned in the background art, such as the inconvenience of valve devices in flexibly adjusting the input of different gases, the lack of elastic check valves for the discharged gas, and the impact on the flexibility of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gas valve device, comprising a valve body A and a support frame. The support frame is installed on the side wall of the valve body A, and an electric push rod is provided on the side wall of the support frame, and the electric push rod is movably connected to the support frame. A push arm is installed at the output end of the electric push rod. An outlet pipe, an inlet pipe A, and an inlet pipe B are respectively installed on the outer wall of the valve body A, and the outlet pipe, inlet pipe A, and inlet pipe B are all connected to the valve body A. A valve body B is installed at the end of the outlet pipe away from the valve body A. An L-shaped arm is provided at the end of the push arm away from the electric push rod. A pin is provided at the end of the L-shaped arm near the push arm, and the L-shaped arm is movably connected to the push arm through the pin. A flow divider is provided inside the valve body A, and the flow divider is slidably connected to the inner wall of the valve body A.

[0008] Preferably, the end of the L-shaped arm away from the push arm is provided with a linkage shaft, and the linkage shaft is movably connected to the A valve body.

[0009] Preferably, the linkage shaft extends through the interior of valve body A, and the linkage shaft is fixedly connected to the flow divider block.

[0010] Preferably, the inside of the diversion block is provided with channel A, and the inside of the diversion block on one side of channel A is provided with channel B.

[0011] Preferably, a bearing shaft is installed inside the B valve body, and a check valve plate is symmetrically and movably installed on the surface of the bearing shaft.

[0012] Preferably, a torsion spring is provided on the bearing shaft surface on one side of the check valve plate, and the two ends of the torsion spring are respectively connected to two sets of check valve plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the valve device not only realizes convenient and flexible adjustment of different input gases and facilitates elastic check of the discharged gas, but also improves the flexibility of use;

[0014] (1) By connecting two different gas pipelines to inlet pipe A and inlet pipe B respectively, valve body B is installed on outlet pipe and connected to external pipeline. Gas is output from outlet pipe through inlet pipe B and channel B. Gas output from outlet pipe enters the interior of valve body B and drives check valve plate to rotate around the bearing shaft and squeeze torsion spring. When no gas passes through, check valve plate is no longer under pressure. Under the elastic cooperation of torsion spring, torsion spring drives two sets of check valve plates to reset and contact valve body A to close, thereby preventing gas from external pipeline from entering the interior of outlet pipe and playing a check function for gas. When it is necessary to change the input When using a different gas, activate the electric actuator, which moves the push arm. The push arm, via a pin, rotates the L-shaped arm, which in turn rotates the diverter block via a linkage shaft. The diverter block then rotates channel A to the space between inlet and outlet pipes, connecting them. Simultaneously, channel B rotates to another position, and the diverter block blocks both the outlet and inlet pipes B. The other gas can then be input through inlet pipe A and discharged through outlet pipe. This allows for convenient and flexible adjustment of different input gases, facilitates elastic check valves on the discharged gas, and improves operational flexibility. Attached Figure Description

A valve body B 5 is installed at the end of the outlet pipe 4 away from the valve body A 1. An L-shaped arm 10 is provided at the end of the push arm 8 away from the electric push rod 3. A pin 9 is provided at the end of the L-shaped arm 10 close to the push arm 8, and the L-shaped arm 10 is movably connected to the push arm 8 through the pin 9. A flow divider block 12 is provided inside the valve body A 1, and the flow divider block 12 is slidably connected to the inner wall of the valve body A 1.

[0023] The L-shaped arm 10 is provided with a linkage shaft 11 at the end away from the push arm 8, and the linkage shaft 11 is movably connected to the valve body 1 of valve A.

[0024] The linkage shaft 11 extends into the interior of valve body 1, and the linkage shaft 11 is fixedly connected to the flow divider block 12;

[0025] The flow divider block 12 has an A channel 13 inside, and a B channel 14 is provided inside the flow divider block 12 on one side of the A channel 13. A bearing shaft 17 is installed inside the B valve body 5, and a check valve plate 15 is symmetrically and movably installed on the surface of the bearing shaft 17.

[0026] A torsion spring 16 is provided on the surface of the bearing shaft 17 on one side of the check valve plate 15, and the two ends of the torsion spring 16 are respectively connected to two sets of check valve plates 15.

[0027] Two different gas pipelines are connected to inlet pipe A (6) and inlet pipe B (7) respectively. Valve body B (5) is installed on outlet pipe 4 and connected to an external pipeline. Gas is output from outlet pipe 4 through inlet pipe B (7) and channel B (14). The gas output from outlet pipe 4 enters the interior of valve body B (5) and drives check valve plate 15 to rotate around bearing shaft 17, compressing torsion spring 16. When no gas passes through, check valve plate 15 is no longer under pressure. Under the elastic cooperation of torsion spring 16, torsion spring 16 drives both sets of check valve plates 15 to reset and contact valve body A (1) to close, preventing gas from the external pipeline from entering the interior of outlet pipe 4, thus acting as a gas check valve. When it is necessary to change to another type of gas... When the electric push rod 3 is turned on, the electric push rod 3 drives the push arm 8 to move.

The diverter block 12 drives the A channel 13 to rotate between the A inlet pipe 6 and the outlet pipe 4, so that the A inlet pipe 6 and the outlet pipe 4 are connected through the A channel 13. At the same time, the B channel 14 rotates to other positions, and the diverter block 12 blocks the outlet pipe 4 and the B inlet pipe 7. Then, another gas is input from the A inlet pipe 6 and discharged from the outlet pipe 4. This realizes convenient and flexible adjustment of different input gases, facilitates elastic check of the discharged gas, and improves the flexibility of use.

[0028] Working principle: Two different gas pipes are connected to inlet pipe A (6) and inlet pipe B (7) respectively. Valve body B (5) is installed on outlet pipe 4 and connected to an external pipe. Gas is output from outlet pipe 4 through inlet pipe B (7) and channel B (14). The gas output from outlet pipe 4 enters the interior of valve body B (5) and drives check valve plate 15 to rotate around bearing shaft 17, compressing torsion spring 16. When no gas passes through, check valve plate 15 is no longer under pressure. Under the elastic cooperation of torsion spring 16, torsion spring 16 drives both sets of check valve plates 15 to reset and contact valve body A (1) to close, thus preventing gas from the external pipe from entering the interior of outlet pipe 4, thereby preventing gas from flowing back. The function of this device is as follows: When it is necessary to change the input of another gas, the electric push rod 3 is opened, which drives the push arm 8 to move. The push arm 8 drives the L-shaped arm 10 to rotate through the pin shaft 9. The L-shaped arm 10 drives the diverter block 12 to rotate through the linkage shaft 11. The diverter block 12 drives the A channel 13 to rotate between the A inlet pipe 6 and the outlet pipe 4, so that the A inlet pipe 6 and the outlet pipe 4 are connected through the A channel 13. At the same time, the B channel 14 is rotated to another position, and the diverter block 12 blocks the outlet pipe 4 and the B inlet pipe 7. Then, the other gas can be input from the A inlet pipe 6 and discharged from the outlet pipe 4. The above is the complete usage of the gas valve device.
