Problems solved by technology

At present, there is no company in China that can meet the needs of customers. For the products of large foreign companies (Air Liquide, BOC, etc.), domestic users have to pay high costs to buy them. With the continuous improvement of users' investment concepts, The cost is also becoming more and more important, and it is also hoped that domestic products with high reliability and relatively low cost can be developed to replace imported products.

Abstract

The invention provides a special gas supply and distribution device and relates to the transportation field of gas with high purity. The special gas supply and distribution device comprises a gas source supplying device (1), valves (21-24), pressure sensors (31, 32), a front segment filter (41), a back segment filter (42), an excess-flow detector (5), a testing port (6), a pneumatic corner valve (7), a vacuum generator (8), a gas cylinder (9) and an untight valve (10). With the specific gas transportation structure adopted, high purity and high cleanliness during the gas transportation are ensured, therefore, the device is safe and reliable. Digital signals are transported to PLC by adopting an RJ45 network wire to substitute analog signals which are used by a traditional control system in the past. The special gas supply and distribution device has the advantages of fast transportation speed, large volume, convenient integration and low cost.

Description

technical field [0001] The invention relates to the field of high-purity gas delivery, in particular to special gas supply and distribution equipment. Background technique [0002] The supply and distribution system of special gas is widely used in high-tech fields such as semiconductors. It provides a solid foundation for the orderly progress of the entire process, and its matching automatic monitoring system has many advantages such as safety and reliability, and is widely affirmed and respected by senior experts. In terms of operation, the tedious and repetitive human labor is replaced by computer calculation, which has achieved remarkable economic benefits. [0003] At present, with the large-scale development of high-tech industries such as semiconductors in China, the demand for special gas supply and distribution systems on the factory side is also increasing, and the requirements for system reliability are also getting higher and higher. At present, there is no com...
