Abstract
The utility model discloses a kind of butterfly valves for granule materials transmission, it includes valve casing and multiple valve bodies, which includes valve rod and flap.The butterfly valve actuating is laborsaving, and can open multiple flaps simultaneously, part flap can be also opened, with the flow of adjusting granule material as needed；Simultaneously granule materials in logistics corridor occur canopy it is stifled when, can also actuating hand handle or so overturning canopy block up the flap at position, carry out pass blocking is stirred by flap.
Description
Technical field
The utility model belongs to valve technology field, more particularly to a kind of butterfly valve for granule materials transmission.
Background technology
In grain and oil processing and other fields, the granule materials such as wheat, corn and soybean mostly use greatly the advection of Large Diameter Pipeline, wind spraying aid type
The vertical pipeline of pipeline or Large Diameter Pipeline, free fall type is transmitted, and the restraining of logistics is generally realized by butterfly valve.Traditional
Butterfly valve existing major defect in the process of running：First, material is easy to overstock under butterfly valve closed state, due to butterfly valve plate face
Product is general bigger, thus opens relatively elaborate, slow movement；It is blocked up second is that butterfly valve position is susceptible to canopy, generally requires pass blocking,
Influence production efficiency；Third, flow is difficult to adjusting control.
CN103759026B discloses a kind of butterfly valve comprising flap is mainly divided into 2 by valve body, valve seat, valve rod, flap
Part, and relief hole is set, leading pressure release before flap integral-rotation is made and is opened step by step when opening, to make the butterfly valve
Opening pressure is smaller, more laborsaving.This structure be suitable for fluid transmission, but in the transmission of the granule materials such as such as grain by
It is typically small in material pressure, and squeeze mutually, the purpose of pressure release is not achieved in smaller relief hole, and substep labor-saving opening also has very much
Limit, and be difficult to solve the problems, such as that material canopy is stifled.
Utility model content
Technical problem to be solved in the utility model is to overcome the drawbacks described above of the prior art, is provided a kind of for particle
The butterfly valve of material transferring, the butterfly valve can preferably solve the problems, such as that particulate matter material shed is stifled, and can to the flow of material into
Row adjusting control.
Realize that above-mentioned purpose is adopted the technical scheme that：It is a kind of for granule materials transmission butterfly valve, including valve casing and
Multiple valve bodies, the valve body include valve rod and flap.
The rectangular logistics corridor of setting in the valve casing.
The flap cross section is fusiformis structure.
Rotation positioning device is arranged in the valve rod.
The butterfly valve for granule materials transmission of the utility model mainly has the advantage that：
1）The butterfly valve is equipped with multiple flaps, and corresponds to distinguish actuating by multiple valve rods, hand handle respectively, thus actuating is compared
It is laborsaving；Furthermore, it is possible to which multiple flaps are opened simultaneously, part flap can be also opened, with the stream of adjusting granule material as needed
Amount；Simultaneously granule materials in logistics corridor occur canopy it is stifled when, can also actuating hand handle or so overturning canopy block up the flap at position, lead to
That crosses flap stirs carry out pass blocking.
2）Fusiformis structure is made in the cross section of flap, it is more laborsaving that actuating overturns flap.
3）By the setting of rotation positioning device, the position that flap turns off or on can be locked, the freedom of flap is prevented
Overturning, and flap can be made to be in semi-open state, it is conducive to relatively accurately control the flow of granule materials.
Description of the drawings
The utility model is described further below in conjunction with the accompanying drawings：
Fig. 1 is the structural schematic diagram of the utility model embodiment one；
Fig. 2 is the structural schematic diagram of flap cross section in embodiment two；
Fig. 3 is the structural schematic diagram of embodiment three.
Specific implementation mode
Embodiment one
As shown in Figure 1, the butterfly valve for granule materials transmission of the utility model, including valve casing 1 and multiple valve bodies, the valve
Body includes valve rod 3 and flap 2, is closely contacted with each other between each flap 2 upon closing.Hand handle 4 is arranged in 3 top of valve rod, for grasping
Make the keying of flap 2.Logistics corridor 1-1 in valve casing 1 can be arranged it is rectangular, in order to the overturning of flap 2.
The butterfly valve is equipped with multiple flaps 2, and corresponds to distinguish actuating, thus actuating ratio by multiple valve rods 3, hand handle 4 respectively
It is relatively labor-saving；Furthermore, it is possible to which multiple flaps 2 are opened simultaneously, part flap 2 can be also opened, with adjusting granule material as needed
Flow；Simultaneously granule materials in logistics corridor 1-1 occur canopy it is stifled when, can also actuating hand handle 4 or so overturn canopy and block up position
Flap 2, carry out pass blocking is stirred by flap 2.
Embodiment two
Referring to Fig. 2,2 cross section of the flap can be made into fusiformis structure, and such actuating overturning flap 2 is more laborsaving.
Embodiment three
Referring to Fig. 3, rotation positioning device can be arranged in the valve rod 3, for example, a positioning disk can be fixedly connected on valve rod 3
5, several arc grooves 5-1 can be arranged in the side of positioning disk 5, and position corresponding with arc groove 5-1 is arranged on the valve casing 1
Blind hole 1-2 for installing shop bolt 6.The position that flap 2 turns off or on can be locked in this way, prevent the freedom of flap 2
Overturning, can also make flap 2 be in semi-open state, relatively accurately to control the flow of granule materials.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, this field
Other modifications or equivalent replacement that those of ordinary skill makes the technical solution of the utility model, without departing from this practicality
The spirit and scope of new technique scheme, are intended to be within the scope of the claims of the invention.
