Abstract

The utility model relates to a time-delaying self-closing flushing device with the inverse flow preventing and energy accumulating function, composed of a one-way valve, an energy accumulating device, and the time-delaying self-closing flushing device. The utility model depends on the one-way valve to prevent the generation of the inverse flow phenomenon when dirty objects are flushed. Through the energy accumulating device, the fixed water quantity and the pressure energy are stored. The flushing force is increased, and the pressure impact in water pipes are conducted to buffer. The self-closing of the flushing process is achieved by the time-delaying self-closing flushing device. The utility model has the advantages of simple structure, small volume, and convenient operation. The utility model is used as flushing devices.

Description

Time-delaying self-closing flusing device with inverse flow preventing and energy accumulating function

The utility model relates to a kind of syringe, particularly a kind of anti-accumulation of energy delay-self-closing syringe of turning one's coat.Present known flushing device has two kinds: a kind of is high and low water tank type syringe, and a kind of is the delay-self-closing flushing valve.High, the box syringe of setting-out has following shortcoming: 1. volume is big, and wasting space is installed; 2. can not the storage pressure energy; 3. leak easily and cause the flood phenomenon; 4. complex structure, easy break-down.The delay-self-closing flushing valve has following shortcoming: 1. owing to rely on water pressure and flow to wash foul, it is very big that the flushing reliability is influenced by hydraulic pressure, discharge; 2. the water inlet caliber that will be provided with is bigger, and waste tubing is installed; 3. during time-delay closing, pipeline has the hydraulic shock phenomenon, fragile pipeline and sealing; 4 when pressure is lower than atmospheric pressure in the pipeline, the phenomenon of easily turning one's coat, polluted source.

The purpose of this utility model is to provide a kind of syringe, makes it to possess simultaneously all advantages of water tank type syringe and delay-self-closing flushing valve, and can overcome its shortcoming.

The purpose of this utility model is achieved in that the anti-accumulation of energy delay-self-closing syringe of turning one's coat of the present utility model is made up of one way valve, accumulator and delay-self-closing flushing valve.Principle of the present utility model is: in use, the syringe water inlet connects water system, and delivery port inserts foul ponds such as urinal by outlet pipeline.The tap water that has certain pressure in the water system enters accumulator through one way valve, and the accumulator leather bag is swollen, and has stored certain water yield and pressure energy.As press delay-self-closing flushing valve knob, and the delay-self-closing flushing valve can be opened, current then flow out the flushing foul from delivery port, accumulator drain charge this moment.To certain hour, flushing valve is closed automatically, the instantaneous rising of hydraulic pressure in the pipeline, and the accumulator leather bag swells, and begins to store the water yield and pressure energy, and compression shock in the buffering pipeline.Above process is gone round and begun again.One way valve has guaranteed that current are unidirectional and has flowed to the foul pond from the water source, and the current in foul pond can't turn back in the water system, have prevented the phenomenon of turning one's coat.Because the energy that flushing ability is stored by accumulator guarantees that the water inlet caliber can design smallerly, whole syringe all seals except that delivery port.

The utility model compared with prior art, remarkable advantage is: 1. can buffer system pressure, the storage pressure energy makes the flushing foul reliable; 2. prevented the indeterminable problem of turning one's coat of common flushing valve; 3. prevented the seepy question of water tank type syringe; 4. guaranteeing to have under the situation of certain flushing ability, volume is little, the water inlet caliber is little, simple in structure; 5. use reliably, not easy break-down.

Concrete structure of the present utility model is provided by the following drawings and embodiment.

Fig. 1 is a kind of structure chart of the anti-accumulation of energy delay-self-closing syringe of turning one's coat of the utility model.

In conjunction with Fig. 1 embodiment of the present utility model is described.

The anti-accumulation of energy delay-self-closing syringe of turning one's coat of the present utility model is made up of one way valve 1, accumulator 2 and delay-self-closing flushing valve 3.One way valve is sat 1e by pedestal 1b. bead 1c, spring 1d and the end and is formed.Spring 1d pushes bead 1c to upper end by base 1e, block water inlet 1a, current can flow into from water inlet 1a, bead is depressed, compression spring 1d, and sit 1e the end of by and go up the aperture 1f that is provided with and enter in the accumulator, and can't enter the water system by bead 1c from the water that delivery port 3e flows backwards back.Accumulator 2 links to each other with one way valve 1, is made up of leather bag 2a, leather bag sheath 2b.Leather bag 2a makes with elastomeric material, and leather bag 2a and leather bag sheath 2b upper and lower end are bonded on the pedestal 1b.Pedestal 1b interlude is shaped on aperture 2c, and current can be entered in the leather bag.The maximum volume of leather bag sheath 2b restriction leather bag 2a expansion bursts leather bag too greatly to prevent that water from pressing.Delay-self-closing flushing valve 3 links to each other with accumulator 2, and the current in the accumulator 2 can enter in the delay-self-closing flushing valve 3.Delay-self-closing flushing valve 3 is made up of valve body 3a, gland 3b, handle 3c, spring 3d, valve core 3f, pressure ring 3g.Rely on hydromechanical bernoulli principle, spool 3f will move right after water flows through delivery port 3e certain hour, close delivery port 3e.Can push spool 3f to the left side by fixed handle 3c, open delivery port 3e.Spring 3d one end bearing plays making handle 3c reset response on pressure ring 3g.Gland 3b is supporting handle 3c.Pressure ring 3g joins and is pressed among the valve body 3a.

Claims

1, a kind of anti-accumulation of energy delay-self-closing syringe of turning one's coat is characterized in that it is made up of one way valve, accumulator and delay-self-closing flushing valve.
