Abstract

The utility model discloses a high-level outlet flushing valve that consists of a valve body, a valve body, a drainage pipe module and an overflow pipe. The valve body takes the shape of tapering type three-way bucket whose upper part is larger than the lower part. The lower side of the tapering mouth is provided with a chute that is provided with an upper opening and is connected with the overflow pipe, the tapering mouth place is provided with a sealing ring that match the valve ball, the valve body is arranged inside the valve cavity of the valve body above the sealing ring, the lower section of the valve body is connected with the drainage pipe module. The utility model has the advantages of simple structure, high level flushing and excellent sealability of the valve ball.

Description

The high water level outlet valve

The utility model relates to syringe, the flusher that particularly a kind of tank for excrement pan is used.

Along with the continuous aggravation of China's water resources consumption, water-saving urgency put people in face of.And the performance of water device and quality directly affect total consumption of water.When using flush toilet, general health people every day is large and small just to be amounted to 3-4 time, will consume the 10-12 premium on currency at least for each person every day.For existing cistern fittings, wash away energy shortage, and, all can occur leaking with after a period of time, wasted great amount of water resources virtually again.

The purpose of this utility model is to provide a kind of high water level outlet valve, and it manages to improve the potential energy of water from flood, changes bigger kinetic energy during the row of dashing into, increases the scouring effect of water, and improves sealing performance, prevents and leaks, the conserve water resource.

For achieving the above object, the high water level outlet valve that the utility model provides, mainly form by valve body, valve ball, sewer pipe connected components and bleed off pipe, it is characterized in that the big up and small down closed-entry threeway of said valve body is cylinder-shaped, reducing position sidewall down is provided with the horizontal also duct of upward opening that goes out in its valve pocket, duct interface and the bleed off pipe formation overfall that joins, reducing place is provided with the sealing ring of using with the valve ball fitted seal in the valve pocket, said valve ball is positioned at the valve body valve pocket of sealing ring top, and valve body hypomere and sewer pipe connected components are matched.

Described sealing ring is the sealing ring of similar " y " type cross section structure.

Compare with existing ball valve, the utlity model has following good effect:

One, comparatively speaking, because discharge level raises, form high water level during draining and dash row, potential energy increases, and impulse force strengthens, and developing result is good naturally, so can reduce water consumption.

Two, valve ball guidance quality in valve pocket is good, is convenient to realize and effectively the closely cooperating of sealing ring that its sealing performance is better than existing sanitaryware accessory.

Three, kept convenience operation.

Four, simple and reasonable, cost is low.

Below in conjunction with accompanying drawing embodiment of the present utility model is illustrated.

Fig. 1 is the utility model structural representation.

Fig. 2 is that the utility model is installed and used view.

Embodiment as shown in Figure 1, the valve body 4 of high water level outlet valve and sewer pipe connected components 8 are connected with thread seal, and valve body is the three way type tubular, its valve pocket up/down perforation, and it is be provided with the reducing 7 of step in the centre, be provided with sealing ring 6, and fixing with trim ring 5 at this position.The valve ball 3 of the band buoyancy of a hollow is arranged in valve pocket, with sealing ring 6 movable articulating sealings.In the valve pocket when anhydrous valve ball float, and be provided with the gap between barrel.The 1st, back-up ring is made the spacing usefulness of valve ball.Be provided with the horizontal duct 9 upwards that goes out among the figure on the valve cavity wall of reducing below 7 left, the duct interface is tightly locked with bleed off pipe 10, above the top be overfall 11.The sealing position of sealing ring 6 generally is provided with little chamfering, also can be designed to the cross section structure of similar " y " type as shown.

Fig. 2 is for using sketch, and the high water level outlet valve 14 shown in the figure is located among the water tank 13 of water closet 12 back, the high-order waterline of 15 expressions.Other annexes such as the water intaking valve in the water tank do not draw.

Its course of work of brief description:

Suppose that water tank installs, it is standby also to be filled with water to the overfall place in the water tank.During use, press the button or depress the water tank handle, valve ball 3 has been carried, because the density of drainage line increases and the buoyancy of the valve ball 3 that hollow sealing is used, extruding valve ball and float and be limited in back-up ring 1 place.High-order water in the water tank is taken the road through valve body valve pocket 2 by force from valve ball 3 sides and is descended, downwards the draining flushing toilet bowl.When the high-order water water yield of setting is put to treating when most, valve ball chamber, deadweight effect lower edge wall guiding drop to realize on the sealing ring 6 self-styled.All communicate by overfall and following ceramic toilet because the valve body reducing is following, so along with water tank water intake, after water inflow valve pocket was crossed valve ball, the static pressure of water increased, and will make sealing effectiveness all the more good with atmosphere.Particularly adopt the sealing ring of special structure, the suitability when more helping improving the sealing contact of valve ball whereabouts.Treat that at last water holds to the overfall place, stop into water, prepare water operation next time.The water yield of using in this device and discharge water at the bottom of traditional water tank mode and under identical water yield situation relatively, to be in high water level potential energy bigger because of it, scouring effect is better.

Claims

1, a kind of high water level outlet valve, mainly by comprising valve body (4), valve ball (3), sewer pipe connected components (8) and bleed off pipe (10) are formed, it is characterized in that the big up and small down closed-entry threeway of said valve body (4) is cylinder-shaped, sidewall under the interior reducing of its valve pocket (2) (7) position is provided with and horizontally goes out and the duct (9) of upward opening, duct interface and bleed off pipe (10) join and form overfall (11), reducing place is provided with the sealing ring of using with the valve ball fitted seal (6) in the valve pocket, said valve ball (3) is positioned at the valve body valve pocket of sealing ring (6) top, and valve body (4) hypomere and sewer pipe connected components (8) are matched.

2, high water level outlet valve according to claim 1 is characterized in that said sealing ring is the sealing ring of similar " y " type cross section structure.
