Abstract
The invention refers to a kind of continuous water hammer water elevator demonstration device. The structure includes a water inlet pipe, supporting pole, a valve, a water outlet pipe, a pressure adjusting room, a piston top end, a piston, a piston cylinder, the water inlet pipe is connected with the piston cylinder, the piston cylinder has a piston, the piston top part has a piston top end, the water outlet pipe is connected with one end of the pressure adjusting room, another end of the pressure room is connected with the water inlet pipe, the pressure adjusting room has a valve, the water inlet pipe is supported by a supporting pole. The merits of the invention are: the piston is easy to be started, the efficiency is upgrades. The upper surface of the piston is cone; it can use the reverse pressure of water between the piston surface and the cylinder top, when two surfaces contact tightly, the delaying force of water in the seam acts principal effect, the reverse pressure vanishes. The sealing between the inlet pipe and the cylinder is good.
Description
Technical field
What the present invention relates to is a kind of continuous type waterram demonstration instrument.Belong to the hydraulics technical field.
Background technique
Piston of the prior art adopts cylinder, and the motion of piston is the power that at random (motion or not sometimes sometimes) moves up and down continuously and will lean on to add.
Summary of the invention
The objective of the invention is to defective, propose piston and adopt the conical surface and cylinder combination, make the randomness of piston motion in the past, become present continuity at above-mentioned existence.Thereby effectively solved piston and started the difficulty that rises, descends in moment.Technical solution of the present invention: its structure comprises intake pipe, strut, valve, outlet pipe, surge-chamber, piston tip, piston, piston/cylinder composition, wherein intake pipe and piston/cylinder join, its connecting part forms an elliptical aperture, piston is arranged in the piston/cylinder, piston head has piston tip, and an end of outlet pipe and surge-chamber joins, and the other end and the intake pipe of surge-chamber join, valve is arranged in the surge-chamber, and intake pipe is by they sup-port.Advantage of the present invention: piston easily starts, and this is because edge shape is more smooth and easy to reduce resistance, improves the reliability of sudden rise and fall, and resistance reduces relatively, and the upper and lower cycle of motion shortens, raises the efficiency.Piston upper surface becomes the conical surface, can utilize the backpressure of water body between piston upper surface and the cylinder body top; And when the plane during with plane contact owing to combine closely, the water body viscous force in the slit plays a leading role, the backpressure disappearance of water, piston do not fall down (this is the shortcoming of original piston structure just).The cylinder partial of piston in combination face of the present invention is to make the aperture of intake pipe and cylinder body junction seal better simultaneously.Move up and down continuously and need not additionaling power.
Accompanying drawing is a structural representation of the present invention
Among the figure 1 is intake pipe, the 2nd, strut, the 3rd, valve, the 4th, the contacting point of intake pipe and piston/cylinder, the 5th, outlet pipe, the 6th, surge-chamber, the 7th, piston tip, the 8th, piston, the 9th, piston/cylinder.
Embodiment
The contrast accompanying drawing, intake pipe 1 joins with piston/cylinder 9, and piston 8 is arranged in the piston/cylinder 9, piston tip 7 is arranged at piston 8 tops, and outlet pipe 5 joins with an end of surge-chamber 6, and the other end of surge-chamber 6 and intake pipe 1 join, valve 3 is arranged in the surge-chamber 6, and intake pipe 1 supports by strut 2.Working procedure:
The current of A, intake pipe 1 rush at piston 8, and rush at piston tip 7 from piston 8 and 9 slits of piston/cylinder, and the piston pulling rod head forms upwards tensile force f
1Piston 8 is subjected to tensile force f
1, buoyancy and the current that flow move upward to reaction force, the acting in conjunction of piston 8.If this moment intake pipe 1 with the contacting point water velocity u of piston/cylinder 9
1＞o; B, when 9 top moments of piston 8 tops and piston cylinder contact, tensile force f
1Become o, the rate of climb of piston 8 becomes o, will be converted into an opposition F
2, the backpressure F that forms of the water body between piston 8 upper surfaces and the cylinder body top
3, piston 8 deadweight G acting in conjunction startup piston 8, make it to move downward.When piston 8 moves to 4 places, contacting point of intake pipe and piston/cylinder, its water velocity u
2=o; The water body speed of the contacting point 4 of C, intake pipe and piston/cylinder is by u
1＞o → water velocity u
2The kinetic energy u that=o had
2/ 2g can not go out certainly, upwards transmits along intake pipe 1, passes to surge-chamber 6 jack-up valves 3 water and flows in the surge-chamber 6, and make surge-chamber 6 superchargings, and when increasing Δ P → o, valve 3 is closed, and because of the pressure in the surge-chamber 6 increases water is flowed out to outlet pipe 5 tops; D, circulation A → B → C form the continuous motion of lower water by the piston outlet pipe 5 that hoists continually and flow out.
