Extension.
According to the flap valve described in the application preferred embodiment, the extension is located on the same line with the valve arm
And it is made into integration.
According to the flap valve described in the application preferred embodiment, the end of the valve arm sets a valve plate rotating shaft, the valve
The middle part of plate is rotatably arranged in the valve plate rotating shaft by an intermediate transit plate, and during reset, the valve plate is set in parallel in institute
State the upper end of valve arm, during discharging, the valve plate is rotated to being stopped operating when being contacted with the extension around the valve plate rotating shaft.
According to the flap valve described in the application preferred embodiment, the intermediate transit plate fixed company vertical with the valve plate
Connect.
According to the flap valve described in the application preferred embodiment, the upper end of the valve body is provided with hopper, the hopper
Positioned at the top of the valve plate, during reset, the valve plate seals the outlet of the hopper.
The utility model also provides a kind of flap valve, and this flap valve is double-layer flap valve, and the flap valve includes two such as
Any described valve body of claim 1-5, two valve bodies are superimposed use up and down.
Compared with prior art, there is following technique effect in the utility model：
The utility model provides a kind of flap valve, and in valve arm and the junction of valve plate, the rear end of valve arm continues rearward to prolong
Stretch an extension, this extension can allow baffle plate unsnatch material after can reset, reset when baffle plate also can adjusting position, from
The sealing of dynamic regulation valve body, and it is simple and practical.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model flap valve；
Fig. 2 is the structural representation of the utility model double-layer flap valve.
Embodiment
Below in conjunction with accompanying drawing, lift a specific embodiment and described in detail.
Fig. 1, a kind of flap valve, including an at least valve body 1 are refer to, a valve arm rotating shaft 6, a valve are set in valve body 1
The valve plate 4 of arm 7 and one, front end and the valve arm rotating shaft 6 of valve arm 7 are rotatablely connected, and valve plate 4 is rotatably arranged on the rear end of valve arm 7, valve arm 7
Rear end also rearward be extended one help valve plate 4 reset extension 8.
In the present embodiment, extension 8 is located on the same line and is made into integration with valve arm 7.
The end of valve arm 7 sets a valve plate rotating shaft 2, and the middle part of valve plate 4 is rotatably arranged on valve plate by an intermediate transit plate 5
In rotating shaft 2, during reset, valve plate 4 is set in parallel in the upper end of valve arm 7, during discharging, valve plate 4 around the rotation of valve plate rotating shaft 2 to extension
Section 8 stops operating when contacting.In the present embodiment, intermediate transit plate 5 is vertical with valve plate 4 is fixedly connected.
The upper end of valve body 1 is provided with hopper 3, and hopper 3 is located at the top of valve plate 4, and during reset, valve plate 4 seals hopper 3
Outlet.
The operation principle of flap valve is to drive valve plate 4 using the rotation of valve arm 7 come the conveying of control material, the drive of flap valve
Flowing mode can select electronic, and pneumatic or carry out control valve switching plate by material dead weight, the present embodiment is with pneumatic control valve plate 4
Exemplified by described in detail, but the utility model is not limited thereto.
Flap valve includes a valve body 1, a pneumatic means and control element, and pneumatic means includes a cylinder, and cylinder is fixed
In in air cylinder supporting structure, air cylinder supporting structure is connected by support with valve body 1, and the output end of cylinder is connected with valve arm 7.Control member
Part includes the tracheae being connected with air cylinder supporting structure, in addition to the magnetic valve being connected with air cylinder supporting structure, such as two-position five-way valve.When need
When conveying material, the stroke of control element drive cylinder changes, so that cylinder drives valve arm 7 around valve arm rotating shaft
6 rotate, and while valve plate 4 follows the rotation of valve arm 7, the weight of material whereabouts press against valve plate 4 and be rotated around valve plate rotating shaft 2, until
When the lower end of valve plate 4 is against extension 8, valve plate 4 stops rotating around valve plate rotating shaft 2, and the unlatching journey of control valve plate 4 is reached with this
The purpose of degree.In abnormal cases, when can not can not be worked such as cylinder, by the hand gear on valve body 1 come band
Dynamic valve arm 7 rotates, so as to open valve plate 4.After valve plate 4 unsnatches material, due to the effect of extension 8, valve plate 4 can reset in time,
Reset when valve plate 4 also can adjusting position, automatically adjust valve body 1 sealing (i.e. valve plate 4 sealing hopper 3 outlet).
It refer to Fig. 2, flap valve when in use, usually stacks up two above-mentioned valve bodies use, i.e., about 1
Double-layer flap valve, double-layer flap valve include two valve bodies 1, and two valve bodies are superimposed use about 1, that is, be divided into valve body and
Lower valve body, upper valve body are opened valve body at present and closed, and upper valve body is closed when lower valve body is opened, in Geldart-D particle material
Air pressure that can also be above and below cut-out cock or material transport environment is when pressure difference be present, while conveying material.
Disclosed above is only the specific embodiment of the application, but the application is not limited to this, any this area
Technical staff can think change, should all fall in the protection domain of the application.
