Abstract
The utility model relates to an energy-saving type free side tumbling type slap door, which belongs to slap doors which are used in pumping stations. The energy-saving type free side tumbling type slap door mainly solves the technical problems that when an existing slap door works, the opening angle is small or the rotation is not flexible, bigger impact force can be generated when the slap door is closed, and the like. The key points of the technical scheme are that an upper hinge and a lower hinge are arranged on a door seat, reaming bases which are matched and connected with the hinges on the door seat are arranged on the door body, a long pin shaft is threaded through the reaming bases and the hinges and are sleeved on the reaming bases and the hinges, and a central line of the long pin shaft is upward and crossed with a central vertical plumb line of the door body. The door seat can adopt a forging flange to weld with a steel pipe, and the door body adopts the forging flange to weld with a door plate which is shaped through forging. The energy-saving type free side tumbling type slap door guarantees the axiality of an upper hinge hole and a lower hinge hole through adopting the long pin shaft, thereby the door body can be rotated more flexibly, the door seat and the door body adopt an integral welding structure, the production and manufacture are more convenient, and the product quality can be effectively guaranteed. The energy-saving type free side tumbling type slap door does not need mechanical and manual control and also can be widely applied in reconstructing slap doors of irrigation and drainage pumping stations.
Description
Technical field
The utility model relates to a kind of irrigation and drainage pumping station cut-off device, particularly a kind of free side turn over flap valve that is used for pumping plant.
Background technique
At present, extensively adopt free floated flap valve in irrigation and drainage pumping station, opening angle is little when work, resistance to water-flow is big, energy consumption is many, can produce bigger defectives such as impact force when flap valve is closed for this flap valve.In recent years, my company had developed the energy-saving free side turn over flap valve of the first generation, and used in a plurality of irrigation and drainage pumping stations, had overcome the defective of free floated flap valve to a great extent, and the user is reflected well.The energy-saving free side turn over flap valve of the first generation some problems also occurred in making course of working, because its main material is a cast steel, when casting casting defect is arranged unavoidably, and as pore, sand hole, slag inclusion, crackle etc., these defectives can influence quality of product; In addition, lower bearing pin is independently two of difference on the energy-saving free side turn over flap valve of the first generation, is difficult for guaranteeing the coaxality of lower bearing pin in the process of making assembling, and this can make the rotation of flap valve door body dumb, influences opening and closing.At the problems referred to above, my company has carried out significant improvement to the energy-saving free side turn over flap valve of the first generation.
Summary of the invention
The purpose of this utility model provides that a kind of body rotates more flexibly, the convenient energy-saving free side turn over flap valve of production and processing.
The technological scheme that its technical problem that solves the utility model adopts is: gate seat 1 is provided with 2 hinges 7 up and down, door body 2 is provided with the free bearing 6 that matches and connect with hinge 7 on the gate seat 1, the axle 8 of having strong market potential passes free bearing 6 and hinge 7 is sleeved on free bearing 6 and the hinge 7, promptly door body 2 is installed on the gate seat 1 by the hinge up and down 7 on have strong market potential axle 8 and the gate seat 1, and the center line of the axle 8 of having strong market potential makes progress and the vertical vertical line in the center of door body 2 intersects.This axle 8 of having strong market potential preferably slopes inwardly 3-8 ° with respect to the vertical vertical line in door body 2 centers.Described axle 8 upper and lower end of having strong market potential can adopt nut 3 fixing.Also can on the nut mounting point of the nut 3 and the axle 8 of having strong market potential, correspondence be provided with the cotter pin mounting hole, be provided with cotter pin (4) in the cotter pin mounting hole.
The utility model also can be equipped with seal ring 9 on the end face of gate seat 1.Or the seal ring mounting groove is set on the end face of gate seat 1, in this seal ring mounting groove, seal ring 9 is installed.
Gate seat 1 of the present utility model can adopt the forging flange to weld mutually with steel pipe, and door body 2 adopts the forging flanges to weld mutually with the door-plate of forging forming.
The beneficial effects of the utility model are: it guarantees up and down pan coaxality by the employing axle of having strong market potential, thereby it is more flexible that a body is rotated; Gate seat and door body adopt the integral solder structure, and production and processing is convenient, and can guarantee quality of product effectively.It need not machinery and manual control, and it also can be widely used in the flap valve transformation of irrigation and drainage pumping station.
