Abstract
The utility model belongs to an automatic floating valve which is used for controlling the water level of various water tanks, water pools, water towers, etc. The utility model is composed of a valve body (1), an I-shaped piston (5), a bottom cover (10), a sleeve barrel (12), and a thimble floating barrel (15), wherein, the piston (5) is arranged in the piston chamber of the inner part of the valve body (1), the top end of the piston is provided with a sealing gasket (6), the bottom end of the piston is provided with a pressurizing hole (8), and the piston uses the knob of a sealing ring gland (9) with small holes, which is communicated with the pressurizing hole (8) to fix an upper sealing ring (7); the bottom cover (10) is provided with a depressurizing hole (11); the sleeve barrel (12) is provided with a vent hole (13) and a drain hole (14). The utility model has the advantages of simple structure, low cost, stable operation, easy starting, and good effect of water level control.
Description
The utility model belongs to the Automatic floating valve that the water level control of a kind of water tank that is suitable for various automatic loading water system, pond, water tower etc. is used.
At present, the water tank of various water-feeding systems, pond, water tower etc., their employed altitude valves, majority are to adopt to belong to Metal Ball and connect a cross bar and compress the float valve that valve carries out water level control; Also there is minority to use float autocontrol valve or piston type combination self-acting valve.The former amplifies buoyancy by lever, kills the water intake of water inlet, has reached the purpose of control water level, because its volume is big, opens not nimble and easy damage, often takes place because of transmitting the ineffective phenomenon that is not closed completely that caused; Though both overcome the back to some extent in the problem that in varying degrees the former is existed, structure is comparatively complicated, and inconvenience is installed, and manufacture cost is also than higher.
The purpose of this utility model provides a kind of simple in structure, easy for installation, manufacture cost is lower, stable performance, unlatching are nimble, water level control is effective Automatic floating valve.
The utility model is made of valve body 1, piston 5, sealing gasket 6, seal ring 7, seal ring gland 9, end cap 10, sleeve 12, thimble floating drum 15.It is achieved in that valve body 1 is provided with water intake 2, water outlet 3; Be provided with the piston chamber 4 bigger than water outlet 3 internal diameters in the valve body, the top is fixed with sealing gasket 6, the bottom is provided with pressurized hole 8 and fixes the I-shaped piston 5 that is of going up seal ring 7 with seal ring gland 9 turn-knobs that are provided with the aperture that is connected with pressurized hole 8 and is placed in one; Valve body 1 top is a cecum, and the side of valve body 1 upper end has the outlet that links to each other with water outlet 3; The fixing end cap 10 that is provided with vent 11 in circle centre position of going up of valve body 1 bottom turn-knob; Its top-side and the bottom that are built-in with thimble floating drum 15 on the end cap 10 tight covers of valve body 1 bottom are fixing are respectively equipped with exhaust port 13 and the sleeve 12 that advances weep hole 14.
Below in conjunction with accompanying drawing description is made in enforcement of the present utility model.
Fig. 1 is a structural representation sectional view of the present utility model.
According to shown in Figure 1, valve body 1 is a three-way pipe, it is provided with water intake 2 and water outlet 3, be provided with the piston chamber 4 bigger than footpath within the water outlet 3 in the valve body 1, sealing gasket 6 is equipped with on the top, the bottom is provided with pressurized hole 8 and fixes the I-shaped piston 5 that is of going up seal ring 7 with seal ring gland 9 turn-knobs that are provided with the aperture that is connected with pressurized hole 8 and is placed in one; Valve body 1 upper end is a cecum, and its side has the outlet that is connected with water outlet 3; Valve body 1 bottom turn-knob is fixed with end cap 10, and the circle centre position of end cap 10 is provided with vent 11; The end cap 10 of valve body 1 bottom is fixed with the sleeve 12 that is built-in with thimble floating drum 15 with tightening cover, the top-side of sleeve 12 is provided with exhaust port 13, the bottom of sleeve 12 is provided with into weep hole 14, and the vent 11 on the end cap 10 is just in time aimed in the position of the thimble of thimble floating drum 15.Except that sealing gasket 6, seal ring 7, each parts all can disposable injection molded.
The utility model mainly is that some the basic physics laws according to liquid are that pressure law and the law of buoyancy design.Its working procedure is as follows: when tap water enters valve body 1 into three-way pipe from water intake 2, the water surface in pond is lower than sleeve 12, thimble floating drum 15 is under the effect of self gravitation, its thimble breaks away from vent 11, vent 11 is opened, the water that is expelled to the Seal cage that is formed by the piston chamber 4 below piston 5 bottoms through pressurized hole 8 flows away from vent 11 rapidly, it is promptly the same with the pressure of water outlet 3 to make that pressure in the sealing chamber equals barometric pressure, this moment is because the area under piston 5 bottoms is bigger than the area of water outlet 3, make piston 5 to lower slider under the pressure action of tap water, water outlet 3 is opened; When the water level in the pond rises to or crosses sleeve 12, along with water level rises, thimble floating drum 15 is under floating function, its thimble stops up vent 11 until blocking fully gradually, owing to continue to pass through pressurized hole 8 toward the Seal cage water filling that forms by the piston chamber 4 below piston 5 bottoms, the pressure in the sealing chamber is constantly increased, the inside and outside pressure of piston 5 upper ends constantly increases, last driven plunger 5 up moves, and stops up and close water outlet 3; When the drawdown in the pond need be intake, thimble floating drum 15 is under the effect of own wt, and its thimble breaks away from vent 11, and the pressure in the Seal cage that the piston chamber 4 that is descended by piston 5 bottoms forms reduces gradually, make piston 5 automatically toward lower slider, water outlet 3 is opened.The utility model has reached the purpose that the water level in pond or water tank or the water tower is controlled automatically to work so repeatedly.
