Pneumatic joint is a connection tool between pipes and pipes, and it is a detachable connection point between components and pipes. It plays an indispensable role in pipe fittings, and it is one of the two main components of hydraulic pipelines.
There are many types of pneumatic joints. Commonly used pneumatic joints can be generally divided into two types: hard pneumatic joints and soft pneumatic joints. According to the connection method of pneumatic joints and pipes, there are three types of hard pneumatic joints: flared type, ferrule type and welding type, and soft pneumatic joints are mainly crimped rubber pneumatic joints.
The advantages of pneumatic joint components have the following 6 points
1. The working medium of pneumatic joint components is inexhaustible air, the air itself does not cost money, the exhaust treatment is simple, does not pollute the environment, and the cost is low.
2. The pneumatic device has a simple structure, light weight, simple installation and maintenance, low pressure level and safe use.
3. High reliability and long service life. The effective number of actions of electrical components is about one million times, while the life of general solenoid valves of Jinan pneumatic components is more than 30 million times, and the life of small valves is more than 200 million times.
4. The adjustment of output force and working speed is very easy. The action speed of the cylinder is generally 50~500mm/s, which is faster than the action speed of hydraulic and electrical methods.
5. Due to the small loss of air flow, compressed air can be supplied centrally and transported over long distances.
6. Pneumatic components utilize the compressibility of air to store energy and realize centralized air supply. It can release energy in a short time to obtain high-speed response in intermittent motion, realize buffering, and have strong adaptability to impact load and overload. Under certain conditions, the pneumatic device can have self-maintaining ability.
Since the pneumatic joint is a detachable connecting element, it must not only meet the requirements of normal connection stability, strong sealing, reasonable size, small pressure loss, good process performance, etc., but also must meet the requirements of convenient disassembly and assembly. . Therefore, don't underestimate the small pneumatic joints, because only its existence can support the existence of the entire hydraulic system.
