In this design, be provided with drainage channel 17 on the valve body 1, drainage channel 17 and delivery port 5 intercommunication, one side that button fixing base 8 is close to second direction logical groove 23 is provided with supplementary exhalant canal 18, the both ends of supplementary exhalant canal 18 correspond intercommunication second direction logical groove 23 and drainage channel 17, after pressing double-button device 6, little button connecting piece 10 leaves the notch that the second led logical groove 23, make second direction logical groove 23 tail end open, rivers enter into the tail end that the second led logical groove 23, get into drainage channel 17 by supplementary exhalant canal again, finally flow to delivery port 5, increase the rivers flow of delivery port 5 play. In this embodiment, the internal diameter of the tail end that leads to groove 22 and the second direction and lead to groove 23 is all greater than other positions internal diameters for first direction, and the cross-section that leads to the tail end that groove 22 and the second direction lead to groove 23 is the echelonment setting, is provided with sealing washer 19 on the ladder that corresponds for it is sealed to stretch into the one end of valve pocket 2 to button fixing base 8, prevents when not pressing to two button device 6, rivers get into the second direction and lead to groove 23, thereby the phenomenon of leaking takes place.

Further, set up spacing driving end 20 on the pore wall of little button lid hole 14, one of little button lid 13 is served and is set up ladder face 21, spacing driving end 20 compresses tightly on ladder face 21. Specifically, through establish on the pore wall in little button lid hole 14 and drive little button lid 13 and carry out the spacing driving end 20 that pushes down in step when pressing big button lid 12, make after pressing big button lid 12, little button lid 13 is also impressed and is pressed groove 11, thereby the drainage 24 of big button connecting piece 9 and little button connecting piece 10 tail end carries out the drainage simultaneously, can be with the discharge that the water yield in the first cavity 27 is more, make the time that the water pressure replied in the first cavity 27 increase, thereby the extension time delay subassembly falls back to the time of delivery port 5, increase the water yield.

Further, the button fixing seat 8 is provided with a first guiding through groove 22 and a second guiding through groove 23, one end of the big button connecting piece 9 far away from the big button cover 12 runs through the first guiding through groove 22, and the small button connecting piece 10 runs through the second guiding through groove 23. In the design, disc-shaped drainage structures 24 are arranged at one ends of the large button connecting piece 9 and the small button connecting piece 10 penetrating through the corresponding first guiding through groove 22 and the second guiding through groove 23, the diameter of each disc-shaped drainage structure 24 is the same as the inner diameter of the tail end of the corresponding first guiding through groove 22 and the tail end of the corresponding second guiding through groove 23, the disc-shaped drainage structures 24 and the corresponding large button connecting piece 9 and the corresponding small button connecting piece 10 are of an integrally formed structure, the disc-shaped drainage structures 24 can increase the contact area with water flow in the first cavity 27, so that water can be discharged from the drainage channel 17 more easily, the first guiding through groove 22 and the second guiding through groove 23 on the button fixing seat 8 can guide the pressing of the large button connecting piece 9 and the small button connecting piece 10, the deviation in the pressing process is prevented, and more water flow cannot be discharged out of the first cavity 27, thereby shortening the water outlet time when large water outlet quantity is needed.

Further, time delay unit 26 is including leading to the needle subassembly and leading to needle fixing base 25, lead to needle fixing base 25 to separate valve pocket 2 for the first cavity 27 that is close to two button device 6 and the second cavity 28 that is close to delivery port 5, lead to needle fixing base 25 and offer logical needle mounting groove 29 near one side of two button device 6, lead to the needle subassembly setting in leading to needle mounting groove 29, lead to the needle subassembly including leading to needle body 30, leading to needle spring 31 and spring fixing base 32, lead to the outside that needle body 30 was established to needle spring 31 cover, just lead to the one end of needle spring 31 and lead to needle body 30 welded fastening, set up spring groove 33 on the spring fixing base 32, the other end that leads to needle spring 31 stretches into spring groove 33 and is connected with spring fixing base 32. Furthermore, a water inlet 35 is formed in the needle fixing seat 25, the water inlet 4 is communicated with the needle mounting groove 29 through the water inlet 35, the spring fixing seat 32 is arranged in the needle mounting groove 29, a through hole 34 is formed in a groove wall of the spring fixing groove, the through hole 34 is communicated with the needle mounting groove 29, and one end of the needle body 30 penetrates through the through hole 34. Through needle body 30 runs through hole 34 and sets up, make through hole 34 in long-term use, impurity in the rivers can cause rivers can't pass through hole 34 from inlet opening 35 to flow to first cavity 27 after plugging up through hole 34, cause the water pressure to reply too slowly or stop replying in first cavity 27, make time delay unit 26 can float and can't return in second cavity 28 and plug up continuous outflow of rivers that delivery port 5 or return caused too slowly, thereby the waste of water resource takes place, produce unnecessary loss.

Specifically, a V-shaped sealing ring 40 is arranged between the delay device 26 and the inner wall of the valve cavity 2, and an opening of the V-shaped sealing ring 40 is arranged towards the water outlet 5, so that water flow is prevented from entering the first cavity 27 from the space between the delay device 26 and the inner wall of the valve cavity 2 when water enters, and the water outlet time is shortened.

Further, delay unit 26 still includes rivers guide 36, rivers guide 36 sets up the one end that is close to delivery port 5 at leading to needle fixing base 25, rivers guide 36 sets up a plurality of guide portions 37 near the one end of delivery port 5, equidistant setting between the guide portion 37. Specifically, by arranging the water flow guide 36, when the water flow flows out from the water outlet 5, the water flow can flow out along the guide part 37 on the water flow guide 36, so that the water flow is prevented from splashing after flowing out in large quantity.

When the delay valve of this design has just been installed on water pipe (not shown), rivers enter into valve chamber 2 through water inlet 4 by the water pipe, valve chamber 2 begins to fill water this moment, make the water pressure of valve chamber 2 be greater than the water pressure of first chamber 27, thereby make delay device 26 move towards first chamber 27 direction, rivers enter into second chamber 28, water pressure when in first chamber 27 increases gradually to the back the same with second chamber 28, delay device 26 returns to initial position, delay device 26 can plug up the delivery port under this state promptly, thereby shut off rivers.
