Abstract
An air charging floating pontoon-type slap door, belongs to technical field of hydraulic engineering equipment. Rubber bladder pontoon slap door and electric control system with air compressor are linked on the support of exit flow path(pipe). The pontoon-type structure comprises steel board enclosure, main beam and secondary beam are arranged inside the body vertically and horizontally separately, the main beam divides the body into four longitudinal lattices and two of them in the middle is provided with rubber bladder which is provided with metal soft tube connecting the air press machine and the other two longitudinal lattices are empty box which can fill foam material inside; the cover board for enclosure of corresponding rubber bladder steel board is provided with hole, which is easy for water flow to pass through the hole, exhaust or enter the empty box quickly when the volume of the rubber bladder changes. The utility model can adjust the opening angle of the slap door to decrease the loss for outlet water when running and make that the hit force is small when dropping; the utility model runs stably and reliably and is convenient to manage and auto control. Air charging floating pontoon-type slap door has advantages of simple and reasonable structure, easy manufacturing, low cost, low maintenance expense and very good value for popularizing and applying.
Description
Technical field
The utility model relates to the blocking device that dams of pump station engineering outlet passage (pipeline), is a kind of structure of novel air-filled floating flap valve, belongs to the hydraulic engineering equipment technical field.
Background technique
Flap valve is pumping plant outlet passage (pipeline) one of closedown mode that dams commonly used, flap valve closedown mode and siphon vacuum destructive valve, the stop gate closedown mode that dams that dams is compared, can shorten outlet pipe (runner) length, be beneficial to the starting and the management of pumping system, construction is transformed for pump station engineering, reducing investment outlay and moving use all has outstanding advantage.Yet also there are two big defectives in existing flap valve locking: the one, and exit head loss is bigger than normal during operation; The 2nd, under water pressure and flap valve deadweight effect, can produce bigger impact force during termination of pumping, the harm engineering safety.In order to reduce exit head loss, improve efficiency of pumping station, people have done many researchs and exploration, and adopting usually increases the flap valve opening angle and reduces exit loss, but opening angle can bring the increase of an impact force when closing after increasing.Adopt hydraulic pressure installation for this reason or change the heavy and door body structure of door and slow down impact force, these measures all exist cost height, difficult in maintenance, problem such as locking is unreliable, effect is not ideal enough.So, exit head loss when reducing to move, alleviate flap valve whereabouts impact force, be the important topic in the pumping plant design all the time.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at existing flap valve, provides a kind of can reduce exit head loss when operation, can alleviate the air-filled floating flap valve of flap valve impact force again when falling.
The purpose of this utility model is achieved in that air-filled floating flap valve, comprise flap valve, rubber pneumatic bag in the flap valve that is hinged on outlet flow (pipeline) bearing and the electric control system that air compressor is arranged, it is characterized in that: flap valve is the case structure that is provided with rubber pneumatic bag.
Described case structure is gone along with sb. to guard him by steel plate, vertically, laterally be respectively equipped with girder and secondary beam in the casing, girder is divided into four vertical lattice with casing, in the middle two vertical lattice rubber pneumatic bag is set, rubber pneumatic bag is provided with the metallic hose that links to each other with air compressor, the cover plate that the steel plate of corresponding rubber pneumatic bag is gone along with sb. to guard him is provided with hole, and avris two vertical lattice are empty van.Be filled with foamed material in the described empty van.Described girder and secondary beam are I-steel.
Behind the starting of pump station, flap valve is dashed by current, treat the normal operation of unit after, by directly rubber pneumatic bag inflation in flap valve of air compressor,, make flap valve be opened into needed angle to increase flap valve buoyancy; After the termination of pumping, manual or electric-linked, open electromagnetic exhaust valve, rely on water pressure to get rid of air in the rubber pneumatic bag automatically, make flap valve around the bearing free fall, to reach impact force when reducing flap valve and falling.
The utility model can be regulated the flap valve opening angle, makes the exit head loss of when operation little, and the flap valve impact force is little during the whereabouts, and it is stable, reliable work, is convenient to management and automation and controls.Air-filled floating flap valve is rational in infrastructure simple, manufactures easily, and cost is low, and maintenance cost is few, and the excellent popularization using value is arranged.Filled and process material in the avris empty van, the steel plate of corresponding rubber pneumatic bag is gone along with sb. to guard him cover plate and is provided with hole, and when being convenient to the rubber pneumatic bag stereomutation, current are very fast by hole, discharge or enter empty van.
