Description
Technical field
The present invention relates to butterfly valve technical field more particularly to a kind of pneumatic multi-pass eccentric-butterfly-valves of heavy caliber.
Background technique
Butterfly valve is called flap valve, is a kind of regulating valve, can be used for the switch control of low pressure pipeline medium.Butterfly valve is according to driving
Mode point: electric butterfly valve, Pneumatic butterfly valve, hydraulic butterfly valve, Hand-operated butterfly valve, according to structure type point: central seal butterfly valve, single bias
Sealed butterfly valve, double eccentric sealed butterfly valves, three eccentricity sealed butterfly valve etc..
Pneumatic butterfly valve is mainly that the piston rod movement band ovable valve stem passed through in starting actuator rotates, and realizes the unlatching of flap
Or it closes.Single eccentric-butterfly-valve is the extruding to solve the problems, such as the butterfly plate and valve seat of butterfly valve, in valve rod and axis deviation butterfly plate
The heart disperses so that butterfly plate upper and lower side be made no longer to become revolution axle center, mitigates the excessive compression of butterfly plate upper and lower side and valve seat.It is double inclined
The heart is to belong to elastic hard sealing, is further improved on the basis of single eccentric, and feature is both to have deviateed butterfly plate center in valve rod axle center,
Body central is also offset from, after being turned on valve, butterfly plate can be detached from rapidly valve seat, and significantly eliminate butterfly plate and valve seat need not
Excessive compression is wanted, phenomenon is scraped, alleviates unlatching resistance away from reduction abrasion improves the service life.Three-eccentric-butterfly-valve is compared in eccentric-butterfly-valve
Other butterfly valves can preferably provide sealing effect and extend the service life of sealing element.Three-eccentric-butterfly-valve refers specifically to stem shaft
The heart deviates disk center and valve body center simultaneously, and valve seat axis of rotation and valve channel axis have certain angle.
For multi-pass pipeline, the butterfly valve of the prior art mainly uses following several mounting means: first, such as patent application
A kind of Three-way butterfly valve disclosed in 201720685835 .4, by installing an independent butterfly valve knot respectively on each water outlet
Structure, when practical operation, by being controlled respectively opposite butterfly valve, to realize the flow direction and flow of water flow.The technical side
There are following technological deficiencies for case: substantially seeing from work there is no linkage effect is generated between two butterfly valves, belongs to two independences
The simple superposition of valve mechanism in the operation of equipment, does not bring improvement effect outstanding on device structure degree of optimization.
For another example Three-way butterfly valve disclosed in patent application 201711158209.0, it is hinged by connecting rod and the valve rod of two butterfly valves, pass through
Connecting rod rotation, is driven two flaps and correspondingly rotates, to realize the closing of two water outlets and the control of flow.It should
There are following technological deficiencies for technical solution: hinged mode, be able to achieve that one of flap is opened, another flap is closed or
Two flaps open the technical effect of certain angle simultaneously, but can not achieve and carry out one of flap individually for property
The flexibility of the linkage of regulation, the i.e. technical approach deduction need to be improved；In addition, due to the leakproofness in order to meet valve,
Junction between valve rod and valve body is provided with many places sealing structure, thus causes valve rod rotary resistance larger, and hinged
The kind of drive acts on valve technology field, through the twisting force of connecting rod on valve rod, is easy to produce the skill of opposite skidding
Art problem influences the normal operation of valve.For another example middle line soft seal Three-way butterfly valve disclosed in patent application 201320190380.0,
The art solutions realize threeway by the way that a flap is diagonally arranged on tube body.Since the valve rod in the technical solution must
The setting of palpus center leads to not the eccentric setting for realizing butterfly valve, and then is difficult to meet the requirement of sealing and flap movement.

Movement.
When needing to flowing into the second isocon its flow and individually being adjusted, Principles of Regulation, mode are referring to above-mentioned
To the mode for flowing into the first isocon its flow and individually being adjusted.
The present invention has the advantages that
(1) first butterfly valve sheet can be realized by adjusting the position of active connection of the invention in formula transmission device that is slidably connected
Body, second butterfly valve ontology be mutually indepedent or connection, cooperates fixed conveyor component of the invention to carry out first butterfly valve ontology, the
Two butterfly valve ontology independently workings or linkage operation, have reached each butterfly valve ontology operating flexibility of raising, independence, linkage
Technical effect.
(2) since the present invention is by the way of through-hole and elastic component cooperation, realize that active connection and fixed guide rotate
Being fastenedly connected or separating between cylinder has easy to operate, efficiently technical effect, due in its end of active connection
Two sides are provided with elastic component, and the first elastic component of multiple groups, the second elastic component cooperate with corresponding through-hole simultaneously, can offer activity company
More binding sites, raising are firmly combined between fitting and fixed guide rotary cylinder.
(3) present invention is by setting pressing type positioning device, passes through matching for convex block in pressing type positioning device and through-hole
It closes, the position of each elastic component of real-time control, guarantees that each elastic component in the state of mobile with active connection, can limit
In the cavity of fixed guide rotary cylinder, it will not be stuck in corresponding through hole because of the rebound effect of each elastic component, and influenced each
The normal movement of a elastic component.
Further, when projection limit is in the cavity of fixed guide rotary cylinder, spring is in compressive state, its end of projection
When portion protrudes into corresponding through-hole, spring is in the raw.The present invention, come the position of limit spring, is guaranteed by positioning loop bar
, can be as much as possible along its radial motion when spring contraction or reset, and spring stress is effectively prevent to tilt, influence projection
Positioning action.Since the outer end of projection is in segment structure, when projection limits the projection in the cavity of fixed guide rotary cylinder
When mobile with active connection, it is smaller with the contact area of guided rotation cylinder inner wall and be able to achieve circle for the projection of segment structure
Sliding touching, can reduce resistance to sliding.Since the end milling of active connection is flat, convenient for positioning the installation of loop bar.
Further, when flap is completed to close, the half of flap one side edge is pressed on one piece of Hough sealing element,
The other half of another side edge is pressed on another piece of Hough sealing element, in this way, to realize under the premise of guaranteeing flap rotation
The tight seal of the internal cavity of flap and valve body.
Further, the present invention is by setting limit socket pipe, so that its end of the first elastic component in the present invention, the second bullet
Property its end of part after being fully removed corresponding fixed guide rotary cylinder, still limit in corresponding limit socket pipe, guarantee the
Its end of one elastic component, its end of the second elastic component are in compressive state always, convenient for continuous operation of the invention.
Further, when active connection rotates, each elastic component is rotated around corresponding annular groove, due to annular groove
Positioning action improves each elastic component in axial positional stability, while also the stationarity for active connection rotation mentions
Support point is supplied.Since the medial surface of annular groove is slope surface, section is V-shaped, when convenient for active connection translation, elastic component
From moving in and out for annular groove.
