PQ40F Eccentric semi-ball valve
Half of an eccentric valve lever has the following advantages:
1. The side mounted light valve quality and compact structure, suitable for the valve installation space with the requirements of the occasion.
2. The fluid resistance is small, its resistance coefficient with section of equal length.
3. Simple structure, small volume, light weight.
4. Cutting function, in the closed to the media clutter (branches, textile bags, etc.) cut off
5. Closely reliable ball valve sealing surface material widely used plastic, sealing good, also has been widely used in the vacuum system.
6. Easy to operate, open and close quickly, from open to close just rotate 90 ¡ã, is advantageous for the remote control.
7. Easy maintenance, ball valve has simple structure, sealing ring, which generally remove replacement is more convenient.
8. In full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, can not cause the valve sealing surface erosion.
9. The applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.Ball rotated 90 degrees in the inlet and outlet should be completely present spherical, thereby blocking flow.
I half of an eccentric valve products are divided into: according to the use of general valve, the pipeline valve, slurry valve, gas valve, oil, chemical valve, pulverized coal injection special valve six big series.Transmission means has manual, pneumatic, electric three, eight classes (PN0.25 ~ 10.0 Mpa) hundreds of specifications (40 ~ 1000) and a half ball valve products.In petroleum, chemical industry, metallurgy, electricity, gas, etc is gate valve, globe valve, Y type valve, ball valve of updated products.Is now popular in the steel industry of pulverized coal injection, pulp, mother liquor and alumina powder conveying alumina industry, electric power industries hydraulic ash (or dry), petrochemical industry, gas industry, etc.
Leveraged half of an eccentric valve industry
General valve: reasonable design, compact structure, small flow resistance, good seal, flexible operation of the light, especially for medium such as water, sewage, steam, pulp of low pressure pipe network, to make electric and pneumatic device, which can realize remote automation.(water, steam, water, pulp, mud and other non corrosive medium)
Special: pulverized coal injection is used to control dust and gas fluid conveying of pulverized coal injection and other solid particles of ideal equipment, widely used in metallurgy, mineral processing, such as electricity production process of pulverized coal, the coal pulverizing system and the cleaning of all kinds of line control.It USES a straight-through type structure, flow unimpeded, won't appear heavy congestion phenomenon, seal the Co - Cr - W alloy material, with special heat treatment, anti-scouring wear-resisting valve, eccentric spherical valve with automatic compensation performance at the same time, through adjusting bolt on the worm gear, make the seal under the condition of a certain degree of wear and tear, still can reach to the effect of the seal.(dust, particle fluid gas)
Petrochemical special: in view of the petroleum and chemical industry to use high pressure, high temperature, full of inflammable, explosive, generally weak acid weak base is easy to corrosion medium, has good sealing, corrosion resistance, opening and closing of portable, automatically remove valve surface fouling characteristics, applicable to the media such as crude oil, heavy oil and oil cracking, food production and other processes.(oil, natural gas, coal gas, water, etc.)
Special: blast furnace gas, gas seal USES Cr, Mn, Si hard alloy, refractory explosive-proof anti-static, seal resistance to high temperature 560 ¡æ, its ability to resist corrosion and anti-seizure are 6 times more than stainless steel seal, is suitable in the gas, coke oven gas, water gas, liquefied petroleum gas, natural gas pipelines and pressure gate website use.(blast furnace gas, natural gas, dust, gas, etc.)
Slurry mixed fluid is special: transport easily precipitated scaling, crystallization precipitation solution of pulp, slurry ash and other process in the two phase mixed fluid is the most ideal process valves, can break when closing scale obstacles to successfully closed.Its novel structure, unique design, with high efficiency and energy saving, good abrasion resistance, reliable sealing, convenient operation, opening and closing fast, long service life, etc.(such as process slurry, slurry ash containing particulate matter transport)
Pipeline is special: belong to straight through half a ball valve, without reducing the body channel and pipeline connection pipe into a straight pipe are interlinked, equal sectional area and less than reducing resistance, full open and full closed as long as the rotation can reach 90 degrees, convenient for long distance pipeline control.(pulverized coal injection and gas supply)
