Description
Technical field
The present invention relates to check-valves technical field, a kind of adjustable type water conservancy check-valves is particularly belonged to.
Background technology
Check-valves refers to be flowed in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and its Main Function is to prevent medium from falling
Flow, prevent pump and drive motor from inverting, and vessel media is released.
By after long-time use, flap is easy to break down existing check-valves, so as to cause flap to close,
So as to lose the function of non-return.
The content of the invention
It is an object of the invention to provide a kind of adjustable type water conservancy check-valves, the deficiencies in the prior art are overcome, in activity
Flap is leaned on the basis of gravity return, then the ability of movable flap return is improved by spring structure, while bottom is provided with facing
When fixing device, movable flap return is drawn by temporary fastening device, further strengthen the sealing after its return, tie
Structure is simple, and maintenance cost is low, and the scope of application is wide.
To solve the above problems, the technical solution used in the present invention is as follows：
A kind of adjustable type water conservancy check-valves, including body, described body one end are provided with the perpendicular connection ring one, other end
The connection ring two for inclining and installing is provided with, the described top of connection ring two is provided with movable flap by way of being hinged, described
Movable flap top be provided with extension board one, lower section and be provided with extension board two, the described top of connection ring two is provided with and extension board one
Corresponding baffle plate, is provided with spring structure between described extension board one and baffle plate, described body lower section is provided with and extension board two
Corresponding temporary fastening device.
Further, described fixing device is electromagnet or permanent magnet, and described extension board two is iron plate.
Further, the side coordinated with movable flap in described connection ring two is provided with step ring, outside described step ring
Portion's diameter is less than the outer dia of connection ring two.
Further, the one side for coordinating with connection ring two on described movable flap is provided with the circular trough coordinated with step ring
Mouthful, described circular notch is with diameter greater than step ring outer dia, less than the outer dia of connection ring two.
Further, described circular pocket bottom is provided with caulking gum.
Compared with prior art, implementation result of the invention is as follows for the present invention：
A kind of adjustable type water conservancy check-valves of the present invention, on the basis of movable flap leans on gravity return, then by spring knot
Structure improves the ability of movable flap return, while bottom is provided with temporary fastening device, work is drawn by temporary fastening device
Dynamic flap return, further strengthens the sealing after its return, and simple structure, maintenance cost is low, and the scope of application is wide.
