Description
Technical field
When The present invention be directed to in-pipe flow directive symmetroid plate, the variation of water body section kinetic energy, flow velocity direction, reacting force etc. in the plate, and a kind of T type monomer vertical fluid momentum instrument of design.It belongs to the hydraulics technical field.
Background technology
Showing and measuring in-pipe flow directive symmetroid plate, during the suffered impulsive force size of curved slab, have dual mode, a kind of is the water intaking flat fire stream dynamometry mode of using always, this kind design, and the impulsive force of surveying size physical concept defines fuzzy; Another kind be at present with, get the vertical fluid mode, physical concept defines vertical fluid momentum instrument concatermer dynamometry structure clearly, but this kind dynamometry structure, adopt the design (concatermer structure) of two fulcrums, design is too complicated, it switches through in the biography of power and moves, and the error stack occurs and transmits, on dynamometry precision and usability, undesirable, thereby prior art exists not enough.
Summary of the invention
The object of the invention provides a kind of employing vertical fluid, the design of single fulcrum structure, and the monomer structure that its dynamometry main structure body adopts vertical rod vertically to connect horizon bar designs, and is simple in structure, the T type monomer vertical fluid momentum instrument of avoiding the error stack to transmit.
The present invention adopts following technical scheme for achieving the above object:
A kind of T type monomer vertical fluid momentum instrument, comprise reserve tank, the stabilized pressure pump that is connected with reserve tank, vertical fluid mechanism is arranged on the top of reserve tank, described vertical fluid mechanism comprises the vertical fluid pipe that is arranged in reserve tank inside, the water inlet of vertical fluid pipe is connected with stabilized pressure pump, the water delivering orifice symmetrical arrangement curved slab of vertical fluid pipe, the water delivering orifice of described vertical fluid pipe and symmetroid plate are arranged in the jet case, and the intersection of reserve tank and jet case arranges jet case freeing port; The conjuncted vertical rod of T type is arranged in the upper end of jet case, and T type simply connected body vernier scale is arranged in the upper end of the conjuncted vertical rod of T type, arranges mobile counterweight, fulcrum, adjusting rider respectively on the T type simply connected body vernier scale.
The present invention adopts technique scheme, compared with prior art has following advantage: its structure of apparatus of the present invention is made up of three parts: water supply part, vertical fluid mechanism and T type simply connected body examination force mechanisms.At water supply part, reserve tank, stabilized pressure pump, jet pipe and flowmeter are set, working mechanism: stabilized pressure pump makes the water of reserve tank export the level pressure jet with certain head at jet pipe, and the flowmeter on the jet pipe measures flow in the pipe.In vertical fluid mechanism part, jet pipe outlet, symmetroid plate and freeing port are set, working mechanism: by vertical fluid, make that stressed to make progress in level that projection makes a concerted effort be zero to curved slab.At T type simply connected body examination force mechanisms T type simply connected body vernier scale, mobile counterweight, fulcrum, leveling rider, T type simply connected body vertical rod, symmetroid plate are set partly, working mechanism: by the leveling rider, leveling T type simply connected body examination force mechanisms initial equilibrium conditions, the moment that relies on mobile counterweight that fulcrum is produced, the moment that the balance vertical fluid produces fulcrum the impulsive force of curved slab.Advantage of the present invention: simple in structure, clear physics conception, having changed horizonally projected jet dynamometry in the past defines fuzzy, on the dynamometry structural design, adopt the design of single fulcrum to replace two fulcrums (concatermer structure) designs, switch through in the biography of power and move, on dynamometry precision and the usability, all be superior to present vertical fluid momentum instrument concatermer dynamometry structure, this momentum instrument cost is lower, is suitable for middle school Popular Science Education and the waterpower experimental teaching of water conservancy class research institutions.
