CNG reducer , technical features double eccentric half ball , the double eccentric half ball valve eccentric , eccentric ball and seat , stem rotates when the common trajectory of self-centering , the closing process more and more tightly closed , fully meet good sealing purposes . Gui Long valve ball and seat completely out , eliminating seal wear, to overcome the traditional ball valve sealing surface of the sphere is always worn with the problem of non-metallic elastic material is embedded in a metal holder , seat metal surfaces are well protection. This product is especially suitable for steel, aluminum , fiber, tiny solid particles, pulp , coal ash, petroleum and other media.

Double eccentric half ball characteristics : First, the sealing ( valve, valve seat ) - bi- metal , metal sphere realized with hard seal ring , fire and explosion ; Second, tight seal , valve and valve seat seal is spherical line contact , by three eccentric achieve zero leakage ; Third, the sealing of the valve leave compensation , to use a longer time to find the valve sealing wear , simply loosen the handwheel side of the stopper bolt , turning a little time off and then , still achieve a reliable seal and prolong life. Fourth, you can twist off compression sleeve , adjust or replace the valve , the valve can continue to use , to avoid the failure of the whole number of the valve seal scrapped drawbacks. Due to welding different alloys ( or a combination of ball ) bi-metal seals can be used for matching vice wear, corrosion resistance , high temperature seals and demanding working conditions .

Double eccentric half ball uses: Universal valves, pipeline valves, slurry special valves, special valves gas , petrochemical special valves , special valves pulverized coal injection six series . In the petroleum, chemical, metallurgy , electricity, gas and other industries are gate valve, globe valve , Y- valve , ball valve replacements. Is now selling in the steel industry pulverized coal injection , aluminum industry, pulp , liquor and alumina powder conveying, hydraulic power industry ( or dry ) ash, petrochemical industry , gas industry and other occasions. Double eccentric half ball of Use: 1 , Universal Valve: rational design , compact structure, with circulation of small resistance , good sealing , light and flexible , especially suitable for water, sewage , steam, pulp and other media of low pressure pipe network, can be formulated electric, pneumatic devices , enabling remote automation. ( Water, steam , water , paper pulp, mud and other non-corrosive media ) . 2 , pulverized coal injection dedicated : the ideal equipment used to control the transport of dusty gas solids , particles of pulverized coal injection fluid , etc., are widely used in metallurgy , mineral processing, power and other blast furnace coal injection in the production process , the milling system and dust removal system in a variety of pipeline control . It uses straight-through structure, smooth flow , fouling and clogging does not occur , sealing using Co-Cr-W alloy , through a special heat treatment , valves, anti-erosion wear resistance, while the eccentric spherical valve with automatic compensation for performance, by adjusting the bolts on the worm , so that in the case of sealing certain degree of wear , and still achieve the effect of re- sealing . ( Dusty gas , particle-fluid ) 3 , petrochemical special : for the petrochemical industry using high pressure, high temperature, filled with flammable, explosive , corrosive generally weak acid weak base medium , with good sealing , corrosion resistance, Kai closed lightweight, can automatically cut the valve surface fouling , etc. , suitable for crude oil, heavy oil cracking and other media transport , food production and other processes . ( Oil, gas, gas, water , etc. ) . 4 , blast furnace gas , gas only: sealing using Cr-Mn-Si alloy , fire -proof anti-static, anti- sealing temperature 560 ℃, its anti- corrosion and anti-bite capabilities are stainless steel sealing over six times , particularly suitable for use on gas, coke oven gas, water gas , liquefied petroleum gas, natural gas pipeline and compression station door . ( Blast furnace gas , natural gas, dusty gas , etc. ) . Special fluid slurry mix : delivery easy precipitation fouling solution crystallization of pulp slurry ash and other processes in the two mixed fluids ideal process valves , can get rid of obstacles to achieve scale in a smooth closed when closed . Its structure is novel, unique design, with high efficiency, good wear resistance, reliable sealing , easy operation, open and close rapidly , long life and other advantages . ( Process slurry ash slurry containing particulate matter , such as transport ) dedicated pipelines : Straight- half ball belongs no necking , pipelines and pipeline valve channel connected to straight pipe interlinked, cross-sectional area equal to the resistance less than necking , all open , fully closed can be achieved simply by turning 90 degrees to facilitate long-distance pipeline transport control . ( Pulverized coal injection and gas transportation )
