Description
Technical field
It the utility model is related to valve technology field, and in particular to a kind of ball valve.
Background technology
Ball valve is a kind of using sphere as opening and closing element, and is driven by valve rod, and the valve to rotate around ball valve axis,
Also it can be used for the adjusting and control of fluid.In China, ball valve is widely used in petroleum refining, long-distance transport pipes, chemical industry, papermaking, system
The industries such as medicine, water conservancy, electric power, municipal administration, steel, occupy very important status in national economy.It has what is be rotated by 90 °
Action, faucet body is sphere, has circular through hole or passage to pass through its axis.
Ball valve is mainly used to make the flow direction for cutting off, distributing and changing medium in pipeline, ball valve optimum switchs,
Stop valve uses, it only needs the rotating torque for the operation and very little being rotated by 90 ° just to close tightly, and because hard seal ball
Together with the sealing ring bottom of valve uses spring sealing ring is tightly embraced with spool, so exceeding the pretension of spring in extraneous strength
Switch is very light during power.General ball valve is more wear-resisting, and since the spool of hard seal ball valve is steel alloy surfacing, sealing ring is alloy
Steel built-up welding, so hard seal ball valve will not produce too big abrasion in switch；And good seal performance, due to hard seal ball valve
Sealing is to use underhand polish, until spool and sealing ring fit like a glove and could use, so his sealing performance is reliable.
Therefore its service life is very long, main field to be applied have oil, chemical industry, power generation, papermaking, atomic energy, aviation, rocket etc. with
And in daily life.

Also it is used in the cooling water system of thermo-power station.Electrical ball valve construction is only made of a few parts, and data, which consumes, to be saved；Volume
It is small, light-weight, installation dimension is small, driving moment is small, easy to operate, quick, and only need to be rotated by 90 ° can fast opening and closing；And also
There is good flow-rate adjustment and close encapsulation characteristic at the same time, in medium-large caliber, the application category of mesolow power, electric ball
Valve is leading valve.When electrical ball valve is in complete unlatching status, butterfly plate thickness is that medium flows through unique resistance during valve body,
Therefore the pressure drop very little occurred by the valve, therefore hold feature with preferable flow.Electrical ball valve have bullet sealing and
Two kinds of seals style of sealing of metal.Elastic packing valve, sealing ring can be embedded on valve body or be attached to butterfly plate periphery.Take
The valve of metal sealing is generally longer than the life of valve of elastic packing, but is difficult to accomplish complete seal.Metal sealing adapt to compared with
High operating temperature, elastic packing then have the shortcomings that by temperature limiting.If ask electrical ball valve to hold as flow to use,
It is important that accurately the size and type of selection valve, the aufbauprinciple of electrical ball valve are particularly suitable manufacture large bore valves.
, can natural subsidence or suction due to contained substantial amounts of particulate matter in fluid in valve body after electrical ball valve long-time service
It is attached to accumulate on valve inner, if these deposits do not do periodic cleaning, the normal use of valve can be influenced.
