Description

Delay flushing valve

Technical field: delay flushing valve of the present utility model relates to a kind of flushing valve technical field, especially belongs to the flush the toilet delay flushing valve technical field of usefulness of a kind of washroom.

Background technology: at present flush the toilet its structure of delay flushing valve of usefulness of used washroom mainly comprises valve body and spool and the handgrip that connects with spool, also has the capping of valve body bottom, spool comprises valve rod and the piston body that connects with handgrip, they are respectively by valve rod spring between valve rod and handgrip and the piston spring support in piston body, wherein the valve rod switch screw that passes valve body is connected with handgrip, an O-ring seal and a plastic seal nut of fixing it are arranged between valve rod and valve body, because the sealing between valve rod and valve body has only a seal point, after the wearing and tearing of sealing circle, just be easy to produce the gas leakage of leaking, and because have only a spring to apply sealing load and reset, easily cause difficult pull switch or poor sealing, thereby cause delay effect undesirable, not enough or the insufficient pressure of draining influences the life-span.

Summary of the invention: the purpose of this utility model provides a kind of good seal performance, delay effect ideal, long delay flushing valve of life-span.For realizing this purpose, delay flushing valve of the present utility model comprises that valve body and spool reach the handgrip that connects with spool, also has the capping of valve body bottom, spool comprises valve rod and the piston body that connects with handgrip, they are respectively by in valve rod spring between valve rod and handgrip and the piston spring support between at the bottom of capping and the piston body, wherein valve rod is made up of axle sleeve and push rod and hold-down nut, piston body is made up of cock body and connecting rod, axle sleeve is fixed in the switch screw of valve body by hold-down nut, also has a sealing ring between axle sleeve and valve body, the big end of push rod places in the axle sleeve, small end passes axle sleeve and fixedlys connected with handgrip, and being equipped with sealing ring at the big end of push rod and shaft room and push rod small end and shaft room, the center, end of the big end of push rod has an axis hole and the connecting rod socket of piston body to reach valve rod to live with the axle sleeve between piston body and be connected.

The cock body of described piston body upper end have one with valve body in the O-ring seal of priming hole sealing, and the stage casing is embedded with a v-seal cushion rubber with the closure orifice seal bottom the valve body.

Described sealing ring at big end of push rod and shaft room is a v-seal cushion rubber, the sealing ring of push rod small end and shaft room comprises the O-ring seal that is enclosed within on the body of rod, be embedded in the sleeve end groove and with the tight v-seal cushion rubber that contacts of the section of stretching out of push rod small end.

Delay flushing valve of the present utility model is owing to adopted valve rod to be connected with the axle sleeve between piston body is alive, there is different springs to reset respectively and applies sealing load, each self-forming of valve rod and piston body independently seals system, therefore the elastic force of its spring does not need just can reach too greatly the purpose that seals and reset, thereby switch just easily promotes, and because the three-layer sealed four road seal points altogether of sealing, push rod and axle sleeve between its axle sleeve and valve body have been adopted in the sealing between valve rod and valve body, so good seal performance, delay effect are just desirable, reach long purpose of life-span.

Description of drawings: delay flushing valve of the present utility model is described in more detail below in conjunction with accompanying drawing.

Fig. 1 is the structure sectional view of the utility model delay flushing valve.

The specific embodiment: by shown in Figure 1, delay flushing valve of the present utility model comprises that valve body 1 and spool 2 reach the handgrip 3 that connects with spool, also has the capping 8 of valve body 1 bottom, spool 2 comprises valve rod 4 and the piston body 5 that connects with handgrip 3, they respectively by the valve rod spring 6 of 3 of valve rod 4 and handgrips and in capping 8 and piston body the piston spring 7 between 5 ends support, wherein valve rod 4 is made up of axle sleeve 10 and push rod 11 and hold-down nut 12, piston body 5 is made up of cock body 13 and connecting rod 14, axle sleeve 10 is fixed in the switch screw of valve body 1 by hold-down nut 12,1 of axle sleeve 10 and valve body also have a sealing ring 9, push rod 11 big ends place in the axle sleeve 10, small end passes axle sleeve 10 and fixedlys connected with handgrip 3, and being equipped with sealing ring at the big end of push rod and 10 on axle sleeve and push rod small end and 10 on axle sleeve, the center, end of the big end of push rod has an axis hole and connecting rod 14 sockets of piston body 5 to reach valve rod 4 to live with the axle sleeve of 5 of piston bodies and be connected.

Cock body 13 upper ends of piston body 5 have one with valve body 1 in the O-ring seal 15 that seals mutually of priming hole, and the stage casing is embedded with the closure orifice seal of a v-seal cushion rubber 16 with valve body 1 bottom.

Sealing ring on 10 on the big end of push rod and axle sleeve is a v-seal cushion rubber 17, the sealing ring that push rod small end and axle sleeve are 10 comprises the O-ring seal 18 that is enclosed within on the body of rod, be embedded in the sleeve end groove and with the tight v-seal cushion rubber 19 that contacts of the section of stretching out of push rod small end.
