Problems solved by technology

Since the free-side flap door is a new type of flap door developed recently, the current technology is not perfect enough, and there are the following shortcomings: the flat structure flap door is a casting, which is relatively heavy, and the door leaf is heavy, which affects the service life of the hinge assembly. It is not conducive to the production of large flaps; because the arc surface is facing outward, there are two eddy current losses in the depressions of the left and right flaps, the flow of water through the door is not good, and the hydraulic loss of the flap is relatively large
Poor seal for large flaps due to limited compression of the "O" ring
The above factors have affected the large-scale development of flap door

Embodiment Construction

[0018] Below in conjunction with accompanying drawing and specific embodiment, the free double-sided flip door of the present invention will be further described:

[0019] figure 1 , figure 2 As shown, a free double-sided flip door includes a door leaf 1, a door seat 2 and a hinge assembly 3, the door leaf 1 and the door seat 2 are connected through the hinge assembly 3, and a vertical beam 21 is arranged in the middle of the door seat 2 , the door leaf 1 is arranged on both sides, the door leaf 1 is arranged as an arc surface, the convex surface of the arc surface of the door leaf 1 faces inward, and the concave surface of the arc surface faces outward. When the flap is opened, the water pressure required to activate the flap is relatively small. When the water pressure pushes the flap open, the water flow is ejected from the flaps on both sides like a rush. See Figure 5 shown. With this structure, when the water passes through the valve, the water flow state is streamli...

Abstract

The invention discloses an injection type double side free flap valve, which comprises a door leaf (1), a door seat (2) and a hinging assembly (3); the door leaf (1) is connected with the door seat (2) through the hinging assembly (3); a vertical beam is disposed on the center of the door seat (2); the door leaf (1) has two sides and is formed into a circular arc with the convex surface towards inside and the concave surface towards outside. The flap valve needs lower hydraulic pressure to start; when the flap valve is opened by the hydraulic pressure, the water injects out on both sides of the valve, and the water passes the valve in a streamline state; consequently, the invention avoids water eddy current loss, reduces water outlet pressure loss, reduces motor power consumption, increases operating efficiency and reduces cost.

Description

Technical field: [0001] The invention relates to a drainage and irrigation pump station for intercepting water when the water pump is stopped, in particular to a free double-sided flip door. Background technique: [0002] The flap gate is used for the drainage and irrigation pump station to intercept the flow when the water pump stops, so as to prevent the backflow of the outer river water. At present, the commonly used flap doors include cast iron flap doors with hanging counterweights, floating box flap doors, and free side flap doors. There are two different structural methods for the free-side flip door. One is a flat structure, which is composed of a door leaf, a door seat and a hinge. The door leaf is a flat structure. The other is the arc surface structure, the door leaf is set as an arc surface, but the arc surface is facing outward, that is, facing the water surface of the outer river. This kind of inner cylindrical surface structure type free side flip door has g...
