Abstract
The present invention discloses a non-leakage water tank capable of regulating and controlling the total quantity of discharged water, which comprises a water inflow device, a water discharge device and a water tank, wherein the water inflow device adopts an internal clogging type structure, and the clogging pressure and the operating speed are far higher than those of the existing external clogging type structure; the water discharge device adopts a compound lever to control the bending degree of an elastic pipe, so the purpose of siphonage water discharge without a water outlet valve can be achieved. The present invention also has the characteristics of no leakage and stepless regulation and control of the total quantity of discharged water.
Description
The present invention relates to a kind of cistern for toilet water-saving cistern, especially a kind of water-saving nonleakage water tank.
Present toilet flush of the prior art all exists the extremely difficult leakage problem of avoiding, and this is that floating ball lever is made circular motion because water intaking valve all adopts floating ball lever formula external seal, and valve sealing element is done the orthoscopic motion.Not matching of two kinds of motion modes, the imbalance that must cause sealing load makes and seals very easily seepage, and shutoff pressure belongs to the zero pressure shutoff basically a little more than opening pressure.
The object of the present invention is to provide a kind of water tank of leak free interior plugging type water feed apparatus.
The present invention has adopted following technical solution: a kind of water-saving nonleakage water tank, it comprises casing, water feed apparatus and jettison gear, water feed apparatus comprises water intaking valve, water inlet pipe, ball float assembly, water intaking valve is connected on the water side of water inlet pipe, wherein water intaking valve is made up of valve rod, valve pocket, valve gap, elastic sealing ring, valve body and activation members, and elastic sealing ring is positioned at the into water inlet end of water, plugging type structure in forming.
In above-mentioned technical solution, described valve pocket can be the spline structure, also can be the lateral flow type structure.
In above-mentioned technical solution, valve pocket in the described water intaking valve and valve body can be integrated.
In above-mentioned technical solution, the elastic sealing ring in the described water intaking valve can be one or more stack, and is separated with the power-assist circle between the elastic sealing ring of stack more than.
Description of drawings of the present invention is as follows:
Fig. 1. structural representation of the present invention;
Fig. 2 spline valve pocket of the present invention structural representation;
Fig. 3 lateral flow type valve pocket of the present invention structural representation;
Fig. 4 another kind of example structure schematic diagram of the present invention.
Below in conjunction with drawings and Examples the present invention is made further explanation and description:
As shown in Figure 1, the present invention is made up of casing 1, water feed apparatus and jettison gear 10, water feed apparatus comprises water intaking valve, water inlet pipe 9 and water inlet float assembly 2, water intaking valve comprises valve rod 5, is enclosed within valve pocket 7 and elastic sealing ring 8, valve gap 3, the valve body 6 on the valve rod 5 and starts spring 4, valve pocket 7 is the spline structure, as shown in Figure 2; Also can be the lateral flow type structure, as shown in Figure 3.Valve pocket 7 is a split-type structural with valve body 6, as shown in Figure 1; Also can be integrated, as shown in Figure 4.Elastic sealing ring 8 can be one, as shown in Figure 1; Also can be more than one stack, and be separated with the power-assist circle between the elastic sealing ring of stack more than, as shown in Figure 4, form, between joint ring 8 and joint ring 11, help moving-coil 12 by two elastic sealing rings.
The course of work of the present invention is as follows: when being in anhydrous state in the water tank 1, start spring 4 and stretch (or counterweight whereabouts) drive valve rod 5 and elastic sealing ring 8 whereabouts naturally, valve is opened automatically, begin water inlet, reach the bottom of ball float assembly 2 when water level, the buoyancy of ball float assembly 2 increases gradually, when buoyancy increases to threshold values, priming starts spring 4 compressions, and guiding valve rod 5 and elastic sealing ring 8 rise and press close to valve pocket 7, at this moment, hydraulic pressure in the water inlet pipe 9 impels valve to fasten, spring force and buoyant equilibrium, water pressure change the power of fastening of inlet valve into, have formed interior plugging structure.When discharging water, when cistern water level drops to a certain degree, when promptly reaching the water outlet threshold values, spring force is higher than buoyancy and fastens the summation of power, and promptly priming valve rod 5 and elastic sealing ring 8 move downward, and open inlet valve, at this moment, the power of fastening that water pressure forms disappears, and begins water inlet.
Compared with prior art there is following advantage in the present invention:
1, adopt interior close measure, the pressure of water inlet pipe if actual shutoff is advocated, namely water tank is filled with water The time, water seal pressure is far above opening pressure, and it is little to have eliminated the shutoff pressure that exists in the existing outer blocking technology The weakness that is higher than opening pressure, and when the water inlet pipe water pressure fluctuations, sealed condition is had no effect, When water surface pressure in the water tank fluctuates in the 10mm water column, response when also it's too late. In addition shutoff campaign, Shutoff power, opening movement, the opening force moving linearly that all is in a straight line has been eliminated several motions The hidden danger of not mating, leaking easily. Put during this interior plugging type water inlet and can effectively solve the water inlet system leakage Water.
2, water intaking valve of the prior art is made up of inlet channel, ball float and lever, its installing space with The whole top that space has occupied inlet water tank adds a side, and the space of leaving outlet valve for is very little, and this The water intaking valve of invention only occupies water tank one side, has reserved activity space for the transformation of outlet system.
