Description

A kind of induction type water tank drain valve

Technical field

The utility model relates to the toilet cistern draining valve, is specifically related to a kind of induction type water tank drain valve.

Background technology

Draining valve is widely used in the toilet cistern, adopts manually openedly mostly, and complex structure uses inconvenience, the existing induction type draining valve that uses, and its complex structure can only singly be used for big draining or little draining, and its displacement is non-adjustable, and can not be dual-purpose.

Summary of the invention

The purpose of this utility model provides a kind of induction type water tank drain valve, can regulate displacement, and is used to have in the high building of water under high pressure and dual-purpose.

A kind of induction type water tank drain valve comprises valve seat, is located at the overflow pipe on the valve seat, is located at the joint ring of valve seat outfall, be located at the guide rod on the joint ring, be located at the time-delay tube on the valve seat, be located at the cover of time-delay tube upper end, be located at the sealed valve core in the time-delay tube, be located at the sliding sleeve on the sealed valve core, guide rod is positioned at sliding sleeve, and sliding sleeve upper end and guide rod threaded engagement are with spring on the sliding sleeve, spring action is between cover and spool, and time-delay tube bottom is provided with water inlet pipe and spilled water hole.

Use for convenience, the time-delay tube is provided with relief hole, can use at the tap water with high hydraulic pressure.

Processor when water inlet pipe and running water outlet end are in series with electromagnetic valve and control electromagnetic valve keying, the infrared induction transmitting and receiving device is located on the toilet lid, be covered with centering block on induced emission and the receiving system, centering block is made as the plane near induced emission and receiving system place, be coated with one deck on the plane and can absorb ultrared skin of paint, when toilet lid was opened the centering block setting, skin of paint blocked on induced emission and receiving system, when covering, centering block leaves induced emission and receiving system.

This draining valve can be distinguished excrements bath, helps the conserve water resource and also helps sanitation of environment and can regulate displacement, can be used for having in the high building of water under high pressure and dual-purpose.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of induction type water tank drain valve, comprise valve seat 1, be located at the overflow pipe 2 on the valve seat 1, be located at the joint ring 12 of valve seat 1 outfall 11, be located at the guide rod 13 on the joint ring 12, be located at the time-delay tube 14 on the valve seat 1, be located at the cover 15 of time-delay tube upper end, be located at the sealed valve core 16 in the time-delay tube 14, be located at the sliding sleeve 17 on the sealed valve core 16, guide rod 13 is positioned at sliding sleeve 17, and sliding sleeve 17 upper ends and guide rod 13 threaded engagement are with spring 18 on the sliding sleeve 17, spring 18 acts between cover 15 and the sealed valve core 16, and time-delay tube 14 bottoms are provided with water inlet pipe 3 and spilled water hole 4.

Use for convenience, time-delay tube 14 is provided with relief hole 141, can use at the tap water with high hydraulic pressure.

Processor when water inlet pipe 14 is in series with electromagnetic valve and control electromagnetic valve keying with the running water outlet end, infrared induction transmitting and receiving device 6 is located on the toilet lid 7, be covered with centering block 5 on induced emission and the receiving system 6, centering block 5 is made as the plane near induced emission and receiving system 6 places, be coated with one deck on the plane and can absorb ultrared skin of paint 51, when toilet lid 7 is opened centering block 5 settings, skin of paint 51 blocks on induced emission and receiving system 6, infrared rays is absorbed, when covering, centering block leaves induced emission and receiving system 6, and electromagnetic valve is opened, and begins bath.

During use, after infrared induction transmitting and receiving device 6 receives the human-induced signal, through modulation, demodulation, amplify the back and insert single chip machine controlling circuit, judge differentiation excrements through the single-chip microcomputer logic, by 6 liters of stool baths; the opening and closing time of 4.5 liters of discharging quantity of water control electromagnetic valve of urine bath; pulse electromagnetic opening of valves; tap water is in water inlet pipe enters time-delay tube 14; move on the sealed valve core 16, water increase in the time-delay tube 14, if when moving on to relief hole 141 on the sealed valve core 16; water is discharged from relief hole 141; move on sealed valve core 16 stops, and sealed valve core 16 drives on the joint rings 12 by guide rod 13 and moves, and valve seat 1 outfall 11 is opened; beginning flushing filth-discharging; close after the pulse electromagnetic opening of valves regular hour, under the effect of spring 18, sealed valve core 16 resets; water is discharged from relief hole 141; enter in the water tank, joint ring 12 resets, and valve seat 1 outfall 11 is closed.
