Abstract
The utility model discloses a flap valve which can restrain the overflow amount of the liquid of overflow section or reduce the impact wave of a pressure pipe. The flap valve comprises a flap valve seat (2). A movable flap valve (3) is equipped to the flap valve seat (2) through a bracket (1). The utility model is characterized in that: the movable flap valve (3) is provided with a through hole (6) and is provided with an auxiliary bracket (4); and the auxiliary bracket (4) is provided with an auxiliary movable flap valve (5) which can close the through hole (6). The flap valve has a simple structure. The movable flap valve can be provided with a plurality of auxiliary movable valve with different standards and different shapes at random positions. The overflow amount of the liquid of overflow section can be controlled or the impact wave of the pressure pipe can be reduced conveniently.
Description
Technical field
The utility model relates to a kind of mechanical device of controlling liquid flow section, specifically a kind of flap valve.
Background technique
Flap valve---mainly be installed on open channel or the pressure conduit, as a kind of one-way valve of control flow cross-section.When current flow along the flap valve direction, wash movable flap valve open by head difference; When the contrary flap valve direction of current flowed, movable flap valve was closed automatically, can be by manually taking away movable flap valve control inflow-rate of water turbine.Material is divided into multiple materials such as stainless steel, cast iron, shaped steel.
Summary of the invention
The purpose of this utility model provides a kind of inflow-rate of water turbine of may command flow section liquid or reduces a kind of flap valve of the shock wave of pressure conduit.
The utility model is to adopt following technological scheme to realize its goal of the invention, a kind of flap valve, and it comprises the flap valve seat, movable flap valve is installed on the flap valve seat by bearing, offer through hole on the movable flap valve, and be provided with secondary bearing, the secondary movable flap valve that can seal through hole is installed on the secondary bearing.
The utility model is to open for making things convenient for flap valve in reverse setting, and movable flap valve, secondary movable flap valve are provided with hook.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, the secondary arbitrarily movable flap valve in a plurality of different sizes, difformity, position can be set on movable flap valve, can control the inflow-rate of water turbine of flow section liquid easily or reduce the shock wave of pressure conduit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As seen from Figure 1, Figure 2, a kind of flap valve, it comprises flap valve seat 2, movable flap valve 3 is installed on the flap valve seat 2 by bearing 1, offers through hole 6 on the movable flap valve 3, and is provided with secondary bearing 4, and the secondary movable flap valve 5 that can seal through hole 6 is installed on the secondary bearing 4.
The utility model is to open for making things convenient for flap valve in reverse setting, and movable flap valve 3, secondary movable flap valve 5 are provided with hook 7.
The utility model can be provided with the secondary arbitrarily movable flap valve 5 in a plurality of different sizes, difformity, position according to actual conditions on movable flap valve 3, also can on the movable flap valve 5 of pair flap valve be set again.Therefore, when normal the use, can control the inflow-rate of water turbine of flow section liquid easily or reduce the shock wave of pressure conduit; Flap valve also can be by linking up with 7 convenience, easily opening flap valve when reverse the setting.
