The worm has not fully welded ball valve, external leakage phenomenon, because the seat is made of carbide teflon seal ring and a spring with coffee, change of pressure and temperature adaptability, pressure and temperature range will not mark any relief slip. The processing of the ball has advanced computer detector, tracking detection, to the sphere of high machining accuracy. Because the material of the valve body is the same as the material of the pipeline, the stress is uneven, and the pipeline can not be aged because of the deformation of the earthquake and the vehicle passing through the ground. The sealing ring body is made of PTFE material of 20%C (carbon) content, so as to ensure no leakage at all.
1, urban gas: gas pipeline, trunk lines and feeder pipelines.
2, central heating: large heating equipment output pipelines, trunk lines, feeder lines.
3, heat exchanger: pipeline and each loop opening and closing.
4, Steel works: all kinds of fluid pipelines, exhaust gas outlets, gas and heat supply pipelines, fuel supply pipelines.
5, all kinds of industrial equipment: all kinds of heat treatment pipeline, all kinds of industrial gas and heat pipe.
The valve is an important executive mechanism of industrial automation control system, remote centralized control can meet the needs of computer program; now widely used in petroleum, chemical industry, gas equipment, nuclear power equipment, water treatment, air conditioning, iron and steel metallurgy, industrial furnace, tank equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, bio pharmaceutical, food machinery, textile, papermaking and other industries, the preferred product is construction of national defense construction, science and technology.
