Technical Field

[0001] The invention relates to the technical field of gas buffering, in particular to a gas buffering device. Background Art

[0002] A pipeline gas buffer is a device used in gas delivery systems to balance and control pressure fluctuations in gas flow, reduce shock and vibration, and improve the safety and stability of the system.

[0003] The patent with patent announcement number CN220980684U involves a gas buffer structure, which belongs to the field of gas buffer technology, including an electronic gas storage tank, which is connected to an electronic gas intake pipe, and a buffer tank structure is installed on the electronic gas intake pipe. The buffer tank structure consists of a buffer tank body and a connecting pipe. There are two connecting pipes and they are symmetrically installed on the outer wall of the buffer tank body. Two gas buffer devices are symmetrically installed in the upper and lower parts of the buffer tank body. The gas buffer device consists of a mounting substrate, a sealing rubber ring, a buffer spring and a buffer air bag. The sealing rubber ring is arranged on the mounting substrate. By arranging the buffer tank structure on the electronic gas intake pipe and arranging the gas buffer device in the buffer tank structure, it can buffer the high-concentration and large-flow electronic gas that instantly flows in, thereby avoiding the overload phenomenon of the electronic gas storage tank during use, and thereby reducing the probability of failure of the electronic gas storage tank.

[0004] In the above patent, it is possible to buffer the instantaneous influx of high-concentration, high-flow electronic gas, thereby avoiding overload of the electronic gas storage tank during use, and thereby reducing the probability of failure of the electronic gas storage tank. However, in actual use, when the gas flow rate inside the pipeline is normal, the gas storage tank may reduce the working efficiency of the equipment. At the same time, some gas may remain in the gas storage tank, which will increase subsequent maintenance costs. For this reason, a gas buffer device with better buffering effect is designed.

[0015] (1) In the gas buffer device, the flow of gas in the pipeline drives the detection plate to rotate around the bottom of the fixed rod. The rotation of the detection plate drives the baffle to move through the connecting rod and the connecting block, so that the gas inside the pipeline enters the interior of the equipment frame through the air inlet. The gas enters the interior of the equipment frame and pushes the buffer plate to move upward. The upward movement of the buffer plate increases the gas storage volume, thereby achieving buffering of the gas inside the pipeline, avoiding a large change in the internal air pressure of the pipeline in a short period of time, which increases the impact on the pipeline and its accessories. Through mechanical transmission, the failure rate of the equipment can be effectively reduced, and the subsequent maintenance cost can be reduced.

[0016] (2) The gas buffer device, the buffer plate moves upward and resets under the action of the No. 2 spring, and reintroduces the gas inside the equipment frame into the interior of the pipeline through the pressure relief frame and the return air port, maintaining the air pressure balance between the equipment frame and the pipeline, avoiding excessive air pressure inside the equipment frame and affecting the subsequent buffering effect. At the same time, when the air pressure in the pipeline exceeds a certain threshold, the buffer plate moves upward and drives the lifting frame to move upward through the push rod, opening the exhaust port on the surface of the buffer frame, so that the gas is discharged to the outside through the exhaust port and the exhaust pipe, avoiding excessive air pressure inside the pipeline exceeding the design tolerance range, thereby reducing the risk of pipeline rupture, explosion or equipment damage.

[0017] (3) The gas buffer device, the lifting frame moves upward to drive the limit rod to move upward and release the limit on the L-shaped rod. After the limit is released, the closing plate moves under the action of air pressure and releases the seal of the exhaust frame to allow the gas to be discharged to the outside, and then resets under the action of the No. 5 spring, which can effectively prevent foreign matter from entering the interior of the equipment frame through the exhaust frame, thereby increasing subsequent maintenance costs. At the same time, the L-shaped rod moves downward to squeeze the telescopic elastic rod to contract. After the telescopic elastic rod contracts, it resets so that the L-shaped rod is limited by the limit rod again, maintaining the stability of the closing plate, preventing it from shaking and affecting the normal use of the exhaust frame, thereby reducing unnecessary maintenance costs.
