Abstract

The utility model relates to an in-line valve type toilet, which takes the pressure media arranged on a waste drain pipe as the action cylinder to drive the drain valve, to finish the opening and closing of the waste drain channel of the toilet. The opening is fluid, and the airproof is reliable, the stored water is suitable, when compared with the common toilet with water storage tank, the utility model saves 2 L of water for one flushing, and the suitable stored water in the toilet is ensured as the pure clear water.

Description

Inline valve formula water closet

The utility model relates to a kind of straightly discharging closet, especially inline valve formula water closet.

At present, known water closet is made up of closet body and serpentine water seal discharge pipe.During the flushing closet, excreta in the closet and water seal water at first are rinsed water and stir and accumulate water level, when the water level in the closet surpasses serpentine water seal peak, containing excremental sewage could discharge, final under the punching press of follow-up water, sewage is poured sewer, when the water level in the closet is lower than serpentine water seal discharge pipe peak, will be dammed by it, make and possess the suitable quantity of water water shutoff in the closet.Because the process of accumulation water level is arranged, so the total amount of flushing water must be greater than water seal water more than one times, could be thoroughly that toilet stool washing is clean, otherwise the water in the closet is exactly the sewage mixed liquor.

The purpose of this utility model provides a kind of improved inline valve formula water closet.It can not only really wash down closet with≤4.5 liters water, and can also prevent the pipe network backing up of sewage.

The purpose of this utility model is achieved in that the exit at the closet body, be shaped on directly downward-sloping blowdown bend pipe, the top at blow-off pipe turning is equipped with a pressure medium pressurized strut, and piston, piston rod, pressure-bearing capsule, spring and axle envelope are installed in the tube; Piston rod stretches in the blow-off pipe, points to the center of blow-off pipe terminal, and the piston rod tail end is equipped with flap, can match with the valve seat of blow-off pipe terminal.If the pressure-bearing capsule expands and makes descent of piston because of entering pressure medium, then flap is pressed on the valve seat, seals sewage draining passage, can water, can prevent the pipe network backing up of sewage again; If pressure-bearing capsule discharge pressure medium and shrinking, then piston is up under the promotion of spring, makes flap break away from valve seat, opens sewage draining passage and can blowdown.

Owing to adopted such scheme, when blowoff valve cuts out, can possess the water of an amount of complete cleaning in the closet, foul smell in the sewage network and sewage all can not on return; When blowoff valve was opened, the sewage in the closet flowed directly into sewer, need not accumulate the necessary water level of crossing water seal, thereby once can save 2 literss of water than the every flushing of conventional closet.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is vertical part sectioned view of inline valve formula water closet.

Among Fig. 1,1. sewage draining passage; 2. connection screwed pipe; 3. piston rod; 4. pressure-bearing capsule; 5. pressure medium interface; 6. piston; 7. spring; 8. cylindrical shell; 9. cleaner; 10. axle seals; 11. flap; 12. valve seat.

In Fig. 1, if having pressure medium to pass through interface [5] enters pressure-bearing capsule [4], then piston [6] is descending because of the pressure effect, drives piston rod [3], and flap [11] is pressed on the valve seat [12], closes sewage draining passage (shown in double dot dash line); If pressure medium is discharged, then piston is up because of the effect of spring [7], drives flap [11] and breaks away from valve seat [12], opens sewage draining passage blowdown (shown in solid line among the figure), and enters next working cycles.Cleaner [9] communicates with atmosphere, replenishes piston [6] and moves up and down necessary air.
