Abstract

The invention provides an air / liquid hybrid type buffer which comprises a cylinder body, a piston rod and a piston. The interior of the cylinder body is divided by the piston into an upper sealing cavity and a lower sealing cavity, and the piston is connected with the piston rod. A first air inlet is formed in the upper sealing cavity, and a second air inlet is formed in the lower sealing cavity.A liquid medium is arranged at the bottom of the lower sealing cavity, and a liquid pipeline communicating the upper sealing cavity with the lower sealing cavity is arranged in the cylinder body. Theposition of the second air inlet is higher than the liquid level of the liquid medium. The first air inlet communicates with the second air inlet. Reset one-way valves are arranged on the piston. Whenthe air pressure in the lower sealing cavity is larger than the air pressure in the upper sealing cavity, the lower sealing cavity and the upper sealing cavity are isolated through the reset one-wayvalves. When the air pressure in the lower sealing cavity is smaller than or equal to the air pressure in the upper sealing cavity, the lower sealing cavity and the upper sealing cavity are connectedthrough the reset one-way valves. The air / liquid hybrid type buffer can achieve the speed reduction effect, the function of additional acceleration is achieved in the speed reduction process, and thebuffer function is achieved.

Description

technical field [0001] The invention relates to the field of buffers or the field of environmental protection, in particular to a gas-liquid hybrid buffer. Background technique [0002] The shock absorber is mainly used to suppress the shock and impact during rebound. It mainly plays a buffering role, and has less impact to protect other structures in the equipment. A large number of shock absorbers in the prior art are mostly spring-type shock absorbers and airbag-type shock absorbers. , it mainly adopts the principle that the spring and air can absorb the impact in the process of compression to play a buffering role. Air conditioner box. Shock absorption and vibration isolation of air compressors, air conditioning units, generators, cooling water towers and other equipment. [0003] In the field of modern environmental protection, in order to deal with emergencies, a quick-closing gate device is set up in a potentially dangerous channel, which requires a quick response t...
