Description
Technical field
This utility model relates to valve technology field, particularly relates to a kind of new-type blocking-up type ball valve.
Background technology
Ball valve, is i.e. that opening and closing element (spheroid) is driven by valve rod, and the valve rotated around ball valve axis.Also can be used for
The regulation of fluid and control, the most firmly seal and have very between V-type ball valve its V-type core and metal seat valve of pile-up welding hard alloy
Strong shearing force, is particularly well-suited to the medium of fibre-bearing, small solid material etc..And multi-pass ball valve not only can be flexible on pipeline
Control the interflow of medium, shunting and the switching flowed to, also can close arbitrary passage simultaneously and make two other passage be connected.This
Class valve the most typically should be horizontally mounted.Ball valve is divided into according to type of drive: pneumatic ball valve, electrical ball valve, manual ball
Valve.In China, ball valve be widely used petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration,
The industries such as iron and steel, occupy very important status in national economy.It has the action of 90-degree rotation, and faucet body is spheroid,
There are manhole or passage by its axis.Ball valve is mainly used to make the flowing side cutting off, distribute and change medium in pipeline
To, it has only to the operation with 90-degree rotation and the least rotating torque just can be closed tight.Ball valve optimum switchs, cuts off
Valve uses.Therefore the airtight performance of ball valve and the flexible performance of regulation and control are had the biggest requirement.
Based on above reason, a kind of new-type blocking-up type ball valve is needed to be devised, by arranging groove and spring, it is achieved
Under the effect of elastic force, reach the requirement of sealing property, and need the flow direction changing medium by compression spring
Realize；By arranging the waterproof layer in sealing block, ensure that the air-tightness in interface channel, a kind of new-type blocking-up further
Type ball valve.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of new-type blocking-up type ball valve.
This utility model is to be achieved through the following technical solutions: a kind of new-type blocking-up type ball valve, including ball valve body, described
Being provided with groove below ball valve body, be connected to spherical pieces by Spring Card in described groove, spiral shell is passed through in the upper end of described spherical pieces
Stricture of vagina linkage section is fixedly installed connecting rod, and described connecting rod is provided with sealing block, described sealing block with the upper wall junction of ball valve body
Inside being provided with waterproof layer, the upper end of described connecting rod is provided with handle；The right-hand member of described ball valve body connects flange-interface.
Further, described handle surfaces is provided with skid resistant course, facilitates staff, prevents from skidding.
Further, described spherical pieces is made up of stainless steel material, corrosion-resistant, prevents from getting rusty.
Further, described groove is arranged in the overhanging protuberance of ball valve body lower end, and described protuberance is cylinder type.
Further, described flange-interface is fixed on the right-hand member of ball valve body by welding manner, by welding, can reach
Reduce weight, save material, the function of resource optimization, and Welding Structure rigidity big, good integrity, be easily guaranteed that again airtight simultaneously
Property and watertightness.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design,
By arranging groove and spring, it is achieved under the effect of elastic force, reach the requirement of sealing property, and need to change the stream of medium
Dynamic direction can be realized by compression spring；By arranging the waterproof layer in sealing block, in ensure that interface channel further
Air-tightness.
