CN2491503Y - Air bag type flushing pressure cistern for toilet - Google Patents

Abstract

Provided is a pneumatic style pneumatic storage tank for flushing a toilet basin. The utility model comprises a hollowly sealed body, a water inlet pipe, a one-way stop valve, a water discharging valve, a water discharging pipe, and an air bag which equilibrates with atmosphere pressure. The air bag is arranged in the sealed hollow body, the water inlet pipe is connected with the body via the one-way stop valve, and the water discharging pipe is connected with the body via the water discharging valve. Tap-water is injected in the tank via the water inlet pipe and the one-way stop valve. The air bag is constantly compressed to contract by the tap-water pressure, and floats in the upper portion of the body, the one-way valve cuts off water source until the air pressure in the air bag equals the tap-water pressure. When the water discharging valve is opened to start work, the air in the air bag expands rapidly to quickly discharge the water to flush the toilet basin. When the water discharging valve is closed, a next working cycle is initiated.

Description

Gasbag-type water closet pan flushing air pressure storage tank

The utility model relates to Flushing cistern for closet; Especially a kind of tap water compressing gasbag storage pressure that utilizes, the gasbag-type water closet pan that can economize on water flushing air pressure storage tank.

Existing Flushing cistern for closet mostly is to utilize the potential energy of its head fall that water closet pan is rinsed well, therefore needs to consume a large amount of water; In recent years there is novel Flushing cistern for closet to appear on the market, as the patent No. is 95217721, name is called " pollution-free vapour-pressure type Flushing cistern for closet ", though have certain pressure memory function, because of it stresses to prevent the pollution of waterhead problem, will not store up and press water saving to be used as a problem to handle, thereby when draining turbulent flow with casing in gas take away gradually, displacement constantly reduces, so that forms negative pressure in the case, arrange not water outlet, and cisco unity malfunction; Desire is got rid of ponding in the case and is replenished air again, and not only water wasting but also time-consuming brings inconvenience and worry to the user.

The purpose of this utility model mainly is the aforementioned disadvantages that exists in the existing water tank in order to overcome, and designs and provides a kind of and not only economized on water, but also can prevent to pollute gasbag-type water closet pan flushing air pressure storage tank easy to use.

Function of the present utility model is achieved in that gasbag-type water closet pan flushing air pressure storage tank, the casing, water inlet pipe, unidirectional stop valve, draining valve, the gutter that comprise hollow seal, it is characterized in that also comprising aerated capsule with the atmospheric pressure balance, aerated capsule is installed in the casing of hollow seal, water inlet pipe joins by unidirectional stop valve and casing, and gutter joins by draining valve and casing.

Air bag almost is full of whole water tank in original state or after finishing flushing, closes draining valve, and water inlet pipe connects unidirectional stop valve, and tap water is through water inlet pipe, unidirectional stop valve water filling in case; Air bag under the effect of tap water pressure constantly compression diminish and float over the top of casing, the air pressure in air bag is when hydraulic pressure equates from the beginning, one way valve cuts off the water source.So then water does not flow backwards the problem at pollution-free water source in the guard box.Open draining valve and enter duty, rapid Peng of gas is expanded in the air bag, and draining flushing water closet pan is closed draining valve and then entered next working cycles fast, and turbulent flow can not taken away the gas in the air bag when draining.

Accompanying drawing 1 is a structural representation of the present utility model.

Below in conjunction with description of drawings.

The 1st, the casing of hollow seal, the 2nd, with the aerated capsule, the 3rd of atmospheric pressure balance, time-delay flushing valve, the 4th, water inlet pipe, the 5th, unidirectional stop valve, the 6th, gutter.

Gasbag-type water closet pan flushing air pressure storage tank, the casing, water inlet pipe, unidirectional stop valve, draining valve, the gutter that comprise hollow seal, it is characterized in that also comprising aerated capsule with the atmospheric pressure balance, aerated capsule is installed in the casing of hollow seal, water inlet pipe joins by unidirectional stop valve and casing, and gutter joins by draining valve and casing.

Draining valve can be the time-delay flushing valve, also can be the draining ball valve.

Usually the Flushing cistern for closet of usefulness only has the 0.5-2.0m head, and the hydraulic pressure of city tap-water pipe network can reach the 28m head.Because the gas coefficient of viscosity is little, expand rapidly, its water velocity is more much higher than the water velocity of using other storage tank, so can economize on water about 20%.Because of air bag is airtight, its gas can't be escaped again, does not then have the problem of inflation again that drains the water away, and is easy to use.

Claims (1)

1. Gasbag-type water closet pan flushing air pressure storage tank, the casing, water inlet pipe, unidirectional stop valve, draining valve, the gutter that comprise hollow seal, it is characterized in that also comprising aerated capsule with the atmospheric pressure balance, aerated capsule is installed in the casing of hollow seal, water inlet pipe joins by unidirectional stop valve and casing, and gutter joins by draining valve and casing.
