Abstract

The utility model discloses a foot pedal type sanitary water-saving valve for flushing the toilet, comprising a water inlet pipe, a water outlet pipe, a foot pedal and a foot pedal fixed seat. Under the function of the spring of the closing-aid spring, the closing clamp plate and the sealing cushion are attached to an upper baffle plate and a lower baffle plate. As a closing valve which has the same direction with the water flow is adopted, the valve is clamped by the pressure of the self weight of the water. The higher the water pressure is, the better the sealing performance is. The utility model uses the foot to pedal and has no use of hands, which prevents the bacteria cross infection and the propagation of the disease. The utility model has the advantages of good sealing performance, simple structure, easy maintenance, sanitation and water saving.

Description

Dash and just use foot-operated sanitary water-saving valve

The utility model relates to a kind of valve, especially relates to a kind of dashing and just uses foot-operated sanitary water-saving valve.

The water tank that dashes just usefulness that uses at present is too high because of installation position, though stronger impact force can be arranged, easily splash bigger spray when current land, and it is also more serious to leak, and rope is also unhygienic with pulling, and repairs cumbersome.The flushing valve of general usefulness also has its shortcoming, as notification number CN2033412U " foot-operated, hand press the dual purpose water-saving flushing valve " though patent simple in structure, be easy to demolition, but adopt the mode that oppositely seals with current to seal water, this sealing means is not very good, easily leak, cause water flow impact pressure to weaken.

The purpose of this utility model is to provide a kind of good seal performance, and simple in structure, dashing of easy-maintaining just used foot-operated sanitary water-saving valve.

The purpose of this utility model is achieved in that the utility model comprises water inlet pipe, outlet pipe, foot rest and foot rest holder, foot rest is the T font, one end of its transverse arm is hinged on the foot rest holder, foot rest can rotate around hinged end, feature is to be processed with the left side wall circular hole in the middle of the left side wall of water inlet pipe and outlet pipe, foreign side stops up with the left side wall circular hole and joins with screw thread, help an end that closes spring to withstand on the centre that foreign side stops up, the other end withstands on the protruding end of closing pressing plate, be processed with perpendicular locating shaft in the centre of closing pressing plate, sealing mat and unlatching push pedal all are enclosed within on the locating shaft, sealing mat is pasting closes pressing plate, open push pedal and be attached on the sealing mat, open the diameter of the diameter of push pedal less than sealing mat; Open push rod and be processed into several fonts, the other end of locating shaft inserts in the hollow of an end of opening push rod, and the other end of opening push rod passes copper sheathing, the right side wall circular hole withstands on the perpendicular arm of foot rest, and sealing ring is enclosed within to be opened on the push rod, be pressed in right side wall circular hole port, fastening with screw; The inwall of water inlet pipe is processed with overhead gage, and the inwall of outlet pipe is processed with lower baffle plate, and overhead gage is parallel with lower baffle plate, closes pressing plate and sealing mat and be close to overhead gage and lower baffle plate under the elastic force effect that helps the pass spring.

The utility model employing helps the pass spring to be close to and closes pressing plate, helping under the elastic force effect of closing spring, close pressing plate and sealing mat and tightly be close to overhead gage and lower baffle plate, close in the same way owing to adopting again with current, pressing plate will be closed and sealing mat compresses by the pressure of water self, hydraulic pressure is high more, close tightly more, sealing performance is also just good more, and the utility model is with foot-operated, need not be manual, can prevent bacterial cross-infection and transmission of disease, therefore the utlity model has good seal performance, simple in structure, easy-maintaining, health, water saving, advantage easy to use.

Fig. 1 is a sectional structure chart of the present utility model.

Fig. 2 is an improvement schematic diagram of the present utility model.

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

Embodiment 1:

In the middle of the left side wall of water inlet pipe 1, outlet pipe 2, be processed with the left side wall circular hole 3 of level, foreign side stops up 4 and joins with screw thread with left side wall circular hole 3, help and close the centre that spring 5 one ends withstand on foreign side's obstruction 4, the other end withstands on the protruding end of closing pressing plate 6, be processed with perpendicular locating shaft 15 in the centre of closing pressing plate 6, sealing mat 7 and unlatching push pedal 16 all are enclosed within on the locating shaft 15, sealing mat 7 is pasting closes pressing plate 6, open push pedal 16 and be attached on the sealing mat 7, open the diameter of the diameter of push pedal 16 less than sealing mat 7.Open push rod 11 and be processed into several fonts, the other end of locating shaft 15 inserts in the hollow 17 of an end of opening push rod 11, the other end of opening push rod 11 passes copper sheathing 14, right side wall circular hole 13 withstands on the perpendicular arm of foot rest 10, sealing ring 18 is enclosed within to be opened on the push rod 11, be pressed in right side wall circular hole 13 ports, fastening with screw 19.Foot rest holder 9 is welded on the sidewall of water inlet pipe 1, and foot rest 10 is the T font, and an end of its transverse arm is hinged on the foot rest holder 9, and foot rest 10 can rotate around hinged end.

Be processed with the overhead gage 8 of level at the inwall of water inlet pipe 1, the inwall of outlet pipe 2 is processed with the lower baffle plate 12 of level, overhead gage 8 is parallel to each other with lower baffle plate 12, close pressing plate 6 and sealing mat 7 and under the elastic force effect that helps pass spring 5, be close to overhead gage 8 and lower baffle plate 12, sealing mat 7 overlaps fully with the contact surface of overhead gage 8, lower baffle plate 12, without any the slit, can separate the water in upper plenum 20 and the following cavity 21 fully.

Embodiment 2:

Present embodiment is the improvement to embodiment 1.

Left side wall circular hole 3, right side wall circular hole 13, overhead gage 8 and lower baffle plate 12 all are processed into oblique having a down dip, angled with level, foreign side stops up 4, helps and close spring 5, closes pressing plate 6, sealing mat 7, unlatching push pedal 16, locating shaft 15, unlatching push rod 11, copper sheathing 14, sealing ring 18, foot rest 10 and foot rest holder 9 and all assembles by embodiment 1.

Embodiment 2 can make full use of the pressure of water self more, compresses more to close pressing plate 6 and sealing mat 7, and sealing performance is also just better.During unlatching, the speed that the water in the upper plenum 20 enters down in the cavity 21 is faster, and impact force also further strengthens.

When need wash, moving foot rest 10 tramps with one's feet, the perpendicular arm of foot rest 10 promotes to open push rod 11 and travels forward, and opens push rod 11 and promotes to open push pedal 16, sealing mats 7 and close pressing plate 6 and throw off contact surface with overhead gage 8, lower baffle plate 12, and current flow to cavity 21 down from upper plenum 20.

Unclamp foot rest 10, close pressing plate 6, sealing mat 7 and open push pedal 16 and press down to overhead gage 8, lower baffle plate 12 in the elastic force effect that is helping pass spring 5, sealing mat 7 is close to contact surface, separate upper plenum 20 and following cavity 21, locating shaft 15 promotes to open push rod 11 and foot rest 10 moves backward, gets back to the position when unclamping.
