An energy-saving lateral fully-automatic non-return device is applicable to irrigation and drainage pumping stations along rivers and lakes. The non-return device comprises a valve base and a closure member arranged at the front port of the valve base. One side of the closure member is connected with the corresponding side of the valve base through a hinge; an included angle formed by the rotating axial line of the hinge and the axial plumb surface of the valve base is 2 to 25 degrees; and an included angle formed by the closed surface of the closure element and the radial section of the valve base is 2 to 25 degrees. The non-return device can be of a single-gate structure, a dual-gate structure, a circular structure and a quadrangular structure. The automatic opening and the closing of the non-return device are realized by utilizing the self-gravity of the closure member through the structural design of the specific non-return device. Furthermore, the utility model can reduce the investment cost of infrastructure construction and devices, and save energy resources.

The utility model content

The purpose of this utility model is, under existing background technology condition, at the deficiencies in the prior art, design the full-automatic check device of a kind of energy-saving side direction type, the closure member that utilizes specific structure design to form realizes cutting out automatically of closure member from gravity, can lower infrastructure and equipment input cost, significantly save the energy.

The technical solution of the utility model is, the full-automatic check device of described energy-saving side direction type comprises valve seat and is positioned at the closure member of this valve seat front port, closure member one side is connected through the respective side of hinge with valve seat, its design feature is that the axial plummet face of the rotation of described hinge and valve seat angle δ is 2 °-25 °; The closed of closure member and valve seat radial section angle α are 2 °-25 °.

Below the utility model made further specify.

Referring to Fig. 1 and Fig. 2, the full-automatic check device of described energy-saving side direction type comprises valve seat 4 and is positioned at the closure member 3 of this valve seat front port, closure member 3 one sides are connected through the respective side of hinge 5 with valve seat 4, its design feature is that the axial plummet face of the rotation of described hinge 5 and valve seat angle δ is 2 °-25 °; The closed of closure member 3 and valve seat radial section angle α are 2 °-25 °.

The axial plummet face of described valve seat was meant the valve seat axis and perpendicular to the plane of horizontal plane, or referred to and this parallel plane plane.

The energy-saving side direction type check device of the utility model can be Fig. 1, shown in Figure 7, and its closure member 3 is the simple gate structure, and promptly described closure member is a whole simple gate, and design feature is that the side closure spare at check device is connected through being connected hinge with the valve seat respective side.When described closure member 3 is the simple gate structure, can be that its left side or right side is connected with the corresponding side of valve seat through connecting hinge, Fig. 1, structure shown in Figure 7 are hinge structure when connecting on the right side.

The energy-saving side direction type check device of the utility model can be Fig. 4, shown in Figure 10, and its closure member 3 is a two-door structure, and promptly closure member is made up of left side closure member and right side closure member.When described closure member was two-door structure, its left side closure member connected with valve seat left side is corresponding through the left side hinge, and the hinge rotation is tilted to the right, with the axial plummet of valve seat cross section angle δ be 2 °-25 °; The right side closure member is connected with valve seat right side correspondence through the right side hinge, and the hinge rotation is tilted to the left, with the axial plummet of valve seat cross section angle δ be 2 °-25 °.

The energy-saving side direction type check device of the utility model can be Fig. 1, circular configuration shown in Figure 7, also can be Fig. 4, square structure shown in Figure 10.When described check device was circular configuration shown in Figure 1, the valve seat radial section was circular, and closure member also be a circle; When described check device was the square simple gate structure of Fig. 7, the valve seat radial section was square, and closure member also is square; When described check device was circular configuration shown in Figure 4, its valve seat radial section was square, and left closure member and right closure member are semicircle; When described check device was square two-door structure shown in Figure 10, its valve seat radial section was square, and left closure member and right closure member are square or rectangular.

Know-why of the present utility model is, adopt the two angle structures of α, δ, utilize closure member from focusing on component on this angle as the power (gravity of utilization only account for energy-saving side direction type check device total weight about 10%) that closes door, it is little that it efficiently solves traditional flap valve opening angle, resistance is big, and flap valve needs problems such as headstock gear; The starting point of its design concept is safe, energy-conservation, efficient, is mainly reflected in: 1. automatically open and close, without any need for headstock gear and other human and material resources, can reduce infrastructure and equipment input cost greatly, significantly save the energy; 2. opening angle is big when work, resistance of medium is little, flow is big for check device, makes to have improved load when having reduced pumping plant work the irrigation and drainage ability, thereby reduced energy dissipation greatly, has improved pumping plant irrigation and drainage in flood season safety factor; 3. open and close freely, stablize during work, impact is little when closing, and has improved the safety of irrigation and drainage pumping station greatly.

It and traditional suspension type flap valve relatively, opening angle is big by 2/3, flow is big by 1/2, flow velocity is high by 1/3, unit efficiency is high by 1/3, energy conservation 22.5%.

As known from the above, the energy-saving side direction type check device of the utility model, it utilizes specific structure design to form and utilizes closure member to realize automatic open and close from gravity, can lower infrastructure and equipment input cost, significantly saves the energy.
