Description
The present invention is meant a kind of float ball valve of the valve block that has quick water inlet and effectively seal especially relevant for a kind of float valve.
General float valve is installed in water tank or the water tower, in order to replenishing of the water yield in control water tank or the water tower, and the structure of existing float valve, as shown in Figure 1, mainly comprise hollow sleeve 10, one end of sleeve pipe 10 is connected intake pipe 20, be provided with plug pipe 11 in the other end, sleeve pipe 10 lower ends also offer water outlet 12, and the interior edge face of plug pipe 11 is provided with sealing gasket 13, and plug pipe 11 perisporium appropriate locations have breach 14, to having hinged-support 15, hinged-support 15 is provided with swing arm 16 to sleeve pipe 10 correspondences at breach 14 places, and an end of swing arm 16 forms pressing part 17 and stretches in the breach 14, the other end connects pole 21, and an end of pole 21 also is provided with ball float 22; The manner of execution of float valve was when the water yield in water tank or the water tower reduces (being that water level reduces) in the past, ball float 22 positions also descend thereupon, and force the pressing part 17 of swing arm 16 upper ends to push plug pipe 11 interior edge faces to the right by pole 21, pass to the right gradually and will fill in pipe 11, the port that the sealing gasket 13 that makes plug manage 11 left ends breaks away from intake pipe 20 inside gradually, form the opening state of intake pipe 20, so, water just can be flowed through intake pipe 20 and water outlet 12 from sleeve pipe 10 lower ends flows in water tanks or the water tower; When the quantity of water in water tank increase, when water level raises gradually, ball float 22 also slowly rises with water level, utilize pole 21 to drive swing arm 16 upper end pressing parts 17, and breach 14 left borders of swing pushing plug pipe 11 left force plug pipe 11 related sealing gaskets 13 gradually to be moved to the left and seal intake pipe 20 to stop into water; But above-mentioned existing float valve sealing gasket still has following shortcoming on control water inlet and sealing water inlet effect:
1. be when the sealing gasket of existing float valve seals intake pipe slowly along with the mobile sealing of filling in pipe, and before sealing gasket does not seal intake pipe as yet, intake pipe still is in into water state, ball float can fluctuate because the ripples in the water tank are moving, cause the wearing and tearing of swing arm and articulating point easily, and when sealing gasket is closed intake pipe, form sealing gasket move left and right and the friction of intake pipe port, cause the wearing and tearing of sealing gasket because of ball float fluctuates.
2. sealing gasket is behind the sealing intake pipe, because sealing gasket is opposite with the direction of water inlet by direction, ball float is to overcome the pressure that current advance, and produces the wearing and tearing of member easily in the junction of ball float and pole and pole and swing arm.
3. because of often carrying more or less impurity (as sandstone etc.) in the water inlet secretly, when sealing gasket is slowly closed into water, sealing gasket is blocked by impurity in the intake pipe port easily and is worn, cause float valve to lose function, may form simultaneously the intake pipe port can't complete closed, and cause the overflow of water tank or water tower at last, waste water resource.
4. because previous reasons causes wear-out failure as sealing gasket, pole, swing arm and articulating point thereof etc., and cause the enclosed point of sealing gasket sealing intake pipe indefinite, can't effectively reach the function of sealing water inlet.
5. existing sealing gasket is slowly to open the intake pipe port, so water intake velocity is slower, inflow is also less.
Main purpose of the present invention provides a kind of float ball valve, has the member of avoiding wearing and tearing, can be effectively and the effect of sealing water inlet apace.
But another object of the present invention provides a kind of moment complete opening water inlet, to reach the float ball valve that water intake velocity is fast and inflow is big.
The objective of the invention is to reach as follows: a kind of float ball valve, comprise: outer sleeve, main ball float, one end of outer sleeve is open shape, to connect intake pipe, the other end is provided with cover plate and is closed shape, and tube wall is provided with water outlet, and water outlet communicates with the end that this outer sleeve is open shape.Main ball float is connected on the outer sleeve by main ball lever, is installed with a push pedal at an end of main ball lever, and push pedal is hinged on the outer sleeve.In the main ball float water is housed, be provided with dividing plate in the described outer sleeve, dividing plate central authorities have water intake, water intake communicates with the water outlet of outer sleeve, also be provided with retaining system mechanism in the described outer sleeve, this retaining system mechanism comprises center-pole, fork, pedestal, stopping plate and elastic element, and center-pole is located in the water intake of dividing plate, and an end stretches through outside described cover plate.Center-pole is provided with latch and bulge loop, and bulge loop is provided with valve block with respect to the end face of water intake, and fork is hinged in the described cover plate, and the groove that the one end passes on the outer sleeve sidewall stretches out outside the outer sleeve, by the secondary ball lever secondary ball float that is connected.Stopping plate is located in the pedestal of cover plate interior edge face, and the one end can fasten with the latch of center-pole, and the other end connects fork, and elastic element is located in the described pedestal, and the one end is against on the described stopping plate, and the other end is against on the pedestal interior edge face.
The correlation of described main ball float and secondary ball float mounting point satisfies: when in the water tank during drawdown, secondary ball float drops to fixed point earlier, make the latch on the stopping plate engaging center-pole, the gravity when descending by main ball float then hits retraction by push pedal with center-pole, forms the unlatching of valve block and intakes.When water level raises, main ball float earlier come-up to fixed point, secondary ball float make along with rising stopping plate break away from center-pole on the engaging of latch, close valve block by the impact of dynamic pressure of intaking this moment, the formation cut-off state.Close the back at valve block and can guarantee that by the static pressure of water cut-off state continues.
