Description
Technical field
The utility model relates to ball valve, in particular to one kind of multiple purposes are eccentrically rotated regulation ball valve.
Background technique
Ball valve is that opening and closing element is driven by valve rod, and the valve to rotate around ball valve axis.Also it can be used for the tune of fluid
Section and control, wherein having very strong shearing between sealing its V-type core of V-type ball valve and the metal seat valve of pile-up welding hard alloy firmly
Power, the medium especially suitable for fibre-bearing, small solid pellet etc..And multi-pass ball valve not only can flexibly control medium on pipeline
Interflow, shunt and flow direction switching, while any channel can also be closed and make other two channel be connected.This class valve exists
It should be generally horizontally mounted in pipeline.Ball valve is divided into according to driving method: pneumatic ball valve, electrical ball valve, manual ball valve.
Existing most domestic eccentric rotary valve uses angle stroke structure, and spool uses eccentric semi-spherical, and valve body also accordingly uses
Eccentric structure, such unlatching moment is small, sensitive, and valve body uses runner straight-through structure, and medium is straight-through, and it is heavy to be not easy to be formed
It forms sediment, anti-plugging performance is good, therefore self-cleaning property is good.But this kind of valve is not suitable for high temperature and pressure occasion, limits use scope.
And traditional ball valve positioning is to go out to install retainer ring additional in bottom flange, due to being in valve inner, it is possible to media contact, therefore hold
Vulnerable to medium influence, service life is short, easy to wear.
Utility model content
For above-mentioned deficiency in the prior art, what the utility model provided one kind of multiple purposes is eccentrically rotated adjusting ball
Valve, compact-sized, high temperature resistant, high pressure resistant, discharge coefficient is bigger, light-weight, high reliablity, regulation performance are more preferable.
In order to reach above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows:
One kind of multiple purposes are eccentrically rotated regulation ball valve, and including split type valve body and upper cover, the upper cover connection is solid
It is scheduled on one end of valve body, the valve body is equipped with bottom plate far from the end of upper cover, and the inside of the valve body is equipped with eccentric semi-spherical shape
The spool of shape and one end of spool are fixedly connected with valve rod, and the valve body corresponds to spool and forms eccentric structure, and the upper cover is separate
The end of valve body be equipped with day font fixed frame, the valve rod by spool end extension connect with the intermediate transverse girder of day font fixed frame and
Valve rod and crossbeam contact jaw are equipped with bearing, and guide sleeve, end of the spool far from valve rod are equipped between the valve rod and valve body
Lower airtight and watertight padding is equipped between valve body, the valve rod is equipped with upper gland packing between upper cover, and the upper outer side of lid, which is equipped with, to be dissipated
Backing is equipped with decompression orifice plate at the valve outlet.
Further, the lower airtight and watertight padding and upper gland packing are flexible graphite packing.
Further, the valve body and upper cover are fixed by screw or bolt.
Further, the decompression orifice plate is no less than between three layers and each layer that there are gaps.
Further, the spool positioning uses collar-type positioning method.
Further, the valve body uses runner straight-through structure.
Further, the upper cover is made of refractory metal material.
The utility model has the following beneficial effects:
The utility model structure is simple, easy to use, and spool uses eccentric semi-spherical, and valve body also accordingly uses eccentric structure,
Unlatching moment is small in this way, sensitive, and valve body uses runner straight-through structure, and medium is straight-through, is not easy to form precipitating, anti-plugging
Can be good, therefore self-cleaning property is good, using the better graphite packing of sealing effect, medium is not easy to outward leakage, and sealing performance is than straight trip
Journey valve improves several times, and due to using eccentric structure, required actuator torque is small, and matched actuator is with regard to small, such complete machine weight
Amount is just light many, day font bracket positioning system, positioned in outside, not with media contact, position more accurate, more can guarantee
Service life and precision, device have cooling fin, and good heat dissipation effect improves the service life, is hardly damaged.
