Accompanying drawing 2 is embodiments of the invention front views, broken section, and valve port shows opening.
The predetermined stepping tank for excrement pan draining valve of booster type of the present invention is shown in accompanying drawing 1. accompanying drawings 2, by pressing dress sealing ring (3), installation nut (2) is provided with valve port (5) above can being installed on the interior draining valve main body (4) of tank for excrement pan, diaphragm seal (6), contraction chamber (35), power-assisted chamber (9), power-assisted plate (32), control chamber (10), control diaphragm seal (12), float (13), motion bar (36), lever (14) airhood (30), tank compositions such as (31), when injecting water with regard to water tank below, the duty of each parts is made description: when cistern water level is set in the height of armlet (20), hydraulic action is in diaphragm seal (6), above the control diaphragm seal (12), each parts remains static, as shown in Figure 1.When pressing little shelves buttons (22) flushing, pass through flexible axle (24) by the power of pressing knob, thimble (26), lever (14), compression press spring (17), lever (14) is turned clockwise by fulcrum (16), bump projection (15) moves upward, projection (15) interlock motion bar (36), control diaphragm seal (12) leaves about control mouthful 3～5mm, the adjustable bobber of promptly being located at above the motion bar (36) (13) is promoted to the complete opening state, water in the water tank flows into through control mouthful (a 11) limbers (8) fast and helps and chamber (9) like this, act on piece power-assisted plate (32) following (power that the power-assisted plate is subjected to is about a times that diaphragm seal is subjected to depth of water pressure power) up and down, make power-assisted plate (32), transition conduit (33) rises, contraction chamber (35) obtains shrinking interlock diaphragm seal (6) and leaves valve port (5) constantly replenishing along with control mouthful (11) water source, open fully up to valve port (5), shown in the accompanying drawing 2, and keep opening.What will say here is, the depth of water pressure power that the buoyancy of float (13) is subjected to less than control diaphragm seal (12), when making control diaphragm seal (12), the power from knob leaves very small distance of control mouthful (11), promptly lean on the automatic complete opening of buoyancy of float (13), like this, as long as set the height of float (13) on motion bar (36), required displacement in the time of can determining to wash, because when float (13) is set in the height of float (37), cistern water level descends four/for the moment, float (37) is a loss of buoyance, interlock motion bar (36), control diaphragm seal (12) together descends, blocking-up enters the water source of control mouthful (11), like this, the interior power-assisted plate (32) in power-assisted chamber (9) can not get replenishing of pressure water source, and diaphragm seal (6) is conducted oneself with dignity and the suction effect of penetrating of valve port (5) circulating water drives transition conduit (33), power-assisted plate (32) descends, and the surplus water in the former power-assisted chamber passes through active face periphery slit through plug hole (34), transition conduit (33) flows into outfall (1).Above-described startup little shelves knobs (22) preestablish the process that discharging quantity of water is washed.Because of the stroke of little shelves knobs (22) is 5 millimeters, protruding tooth (27) above the lever (14) does not mesh with the groove above the airhood (28), lever (14) is subjected to the elastic force of stage clip (17) and resets, and guarantees that projection (15), motion bar (36), control diaphragm seal (12) descend smoothly.The process that discharges water of big once retaining knob (21) is described below again, when pressing big shelves knobs (21), the opening process of valve port (1) is the same with little shelves knobs (22), different is, big shelves knobs (21) make the stroke of thimble (26) reach 8 millimeters by flexible axle (24), increased the anglec of rotation of lever (14), make the protruding tooth (27) above the lever (14) fall within the groove (28) that airhood (30) is provided with above, the buoyancy that is produced in water because of airhood (30) has a power that is rotated counterclockwise by moving fulcrum (29), in the time of under protruding tooth (27) falls within groove (28), promptly produce and nibble, so promptly be float (13 loss of buoyance, also by the lever lifting, little retaining function is ineffective, when drawdown when being lower than airhood (30), airhood (30) loss of buoyance, be subjected to the weight of the deadweight and interior the water of tank (31) that links to each other and reset, mesh the position and come off, lever (14) is subjected to stage clip (17) elastic force and resets, then control mouthful (11), valve port (5) is closed respectively, reaches the discharging of whole box water.Malfunctioning or the damage when water intaking valve, unnecessary water just flows into closet along bleed off pipe (19), power-assisted chamber (9), transition conduit (33), outfall (1).
The present invention compares with existing product, and following advantage is arranged:
1. adopt dull and stereotyped water shutoff, diaphragm seal is not yielding, and the depth of water that diaphragm seal is subjected to is pressed Nearly 2 kilograms of strong cohesiveness is stopped drainage.
