Abstract
The utility model discloses a pedal piston sealing type valve which comprises a valve (7), a water inlet, a water outlet, a piston, a piston rod (6) and a pedal plate (1). The utility model is characterized in that a water inlet in a valve body is lower than a water outlet; the piston and the piston rod (6) are positioned in the valve body, the top end of the valve body is provided with the pedal plate with a self-locking rod (2), and the bottom end is supported by a reset spring (10). The utility model which has the advantages of simple structure, controllable flowing volume and reliable sealing is suitable for being used in water using places such as public places, hospitals, schools, etc.
Description
The utility model relates to foot-operated flashing valve.
The flashing valve that is used for public place and hospital, toilet in the prior art adopts the valve of manually operated type mostly, and this is easy to cause the propagation of bacterium; The foot-operated seal valve that exists in the prior art exists complex structure, the deficiency of wayward water-outlet quantity.
It is a kind of simple in structure that the purpose of this utility model is to provide, and controls flexible foot-operated piston sealed valve.
Above-mentioned purpose of the present utility model is to realize by such technological scheme, be that the utility model comprises valve body, entery and delivery port, piston and piston rod foot treadle, it is characterized in that: the interior water intake of valve body is lower than the water outlet piston and piston is positioned at valve body, the pedal of its top mounting strap self-lock rod, its bottom is supported by Returnning spring, the valve body top is fixed cover plate and dust ring by fixed cover, the ballhead of self-lock rod cooperates with the awl mouth spherical groove at valve rod top, have hook on the self-lock rod, have the hook groove on the fixed cover.
The embodiment of the indefiniteness that above-mentioned purpose of the present utility model can provide by accompanying drawing further specifies.
Accompanying drawing is a structure cut-away view of the present utility model.
Referring to accompanying drawing: piston rod 6 the time, in the valve pocket between the water outlet, the pedal 1 of its top mounting strap self-lock rod 2, its bottom is supported by Returnning spring 10, piston is three piston plates with its one of processing on valve rod 7, have circular groove, seal ring 9 is installed in it, and body cavity has lining 8, and the top of body cavity 7 is fixed cover plate 5 and dust ring 4 by fixed cover.The bottom of the self-lock rod 2 of cover plate is a ballhead, is contained in the awl mouth spherical groove at valve rod top, and makes it be unlikely to deviate from by screw is spacing.Hook on the self-lock rod can articulate with the hook groove on the fixed cover 3 piston stroke is fixed.
The utility model is owing to said structure has the following advantages:
1, simple in structure, be convenient to make and maintenance;
2, controllable flow rate, owing to have control lever, pedal is stepped on backward any Direction moves, and it is logical to unclamp the length that still can keep water behind the pedal.
3, sealing is reliable, can not produce leakage.
The utility model is specially adapted to water occasions such as public place and hospital, school.
