Description

Multifunctional knob type delayed self-close valve

The utility model relates to the valve class, the multi-functional delay self-closing valve of specifically a kind of push button.

Before the utility model proposes, Patent Office of the People's Republic of China had once authorized a kind of name of being applied for by me to be called the utility model patent of " delay self-closing valve " on May 6th, 1992, the patent No. is 91217457.9, and the characteristics of this valve are that delay time can be regulated in 0-120S under different hydraulic pressure.Though the performance of this valve is more superior, because its structure more complicated, so its volume is excessive, cost is higher.Even more serious is, and its conical valve seat center through hole is stopped up by the impurity in the water easily, often causes this valve cisco unity malfunction, influences using effect.

The purpose of this utility model is exactly in order to solve the problem that above-mentioned prior art exists, and provides that a kind of volume is little, cost is low, multi-functional, the multi-functional delay self-closing valve of not susceptible to plugging push button.

The utility model is to improve on the basis of " delay self-closing valve ", it is mainly by capping 1, valve body 14, starter gate valve 5, piston body 7 and button 12 are formed, wherein, valve body 14 has an epicoele 16 and a cavity of resorption 17, the cross section of epicoele 16 is greater than the cross section of cavity of resorption 17, its water outlet is positioned at the axial bottom of cavity of resorption 17, water intake is positioned on the sidewall of epicoele 16, piston body 7 is positioned at epicoele 16, gapped between them, sealing gasket 10 and a leading truck 11 are housed in the lower end surface of piston body 7, leading truck 11 is arranged in cavity of resorption 17, be used to guide the direction of piston body 7 axial motion in epicoele 16, sealing gasket 10 can contact and seal up with the interior edge face between epicoele 16 in the valve body 14 and the cavity of resorption 17, epicoele 16 and cavity of resorption 17 are separated, stop the press water of water intake from then on to flow in the cavity of resorption 17, leather cup 8 is arranged on epicoele 16 inwalls on valve body 14 water intake tops, be contained on the sidewall of piston body 7, and cooperate with epicoele 16 inwalls, epicoele 16 inwall places on water intake have from water intake on the straight line type water chute 15 of top of chamber, water chute 15 is used for the press water of water inlet is incorporated in the epicoele 16 at piston body 7 tops, capping 1 is positioned at the top of epicoele 16, there is an axial hole in central authorities at piston body 7, starter gate valve 5 is pressed on the upper-end surface of this axial hole by the spring 3 that is bearing in the capping 1, between spring 3 and the capping 1 spacer 2 is housed, the thickness that changes spacer 2 can be adjusted delay time.Button 12 is contained on the sidewall of cavity of resorption 16, and tab 13 is installed in the unlatching of its may command starter gate valve 5 additional on button 12.

In sum, the delay time that the utility model aforementioned except having " delay self-closing valve " is had is long, also can proper functioning when delay time can be regulated and hydraulic pressure is very low in pipeline etc. outside the advantage, and the utility model also has following other advantage:

1, structure of the present utility model is greatly simple, and the more above-mentioned prior art of its external dimension has reduced more than 2/3rds, has realized miniaturization, has reduced cost significantly.

2, because water chute 15 of the present utility model is unenclosed constructions, can not stop up conduit pipe, improve the functional reliability of valve because of foreign material in the water.

3, operating button 12 of the present utility model has delay-self-closing and manual control is closed two kinds of functions, and therefore, the utility model can replace at present commercially available all kinds of use in toilet time-delay flushing valves.The utility model is easy and simple to handle, and is durable in use, applied widely.

Followingly specify the utility model with reference to accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the right elevation of Fig. 1.

In Fig. 1 and Fig. 2, valve body 14 is cylindrical shapes, and its inside is divided into 17 two cylindrical cavities of epicoele 16 cavity of resorptions, the diameter of epicoele 16 greater than cavity of resorption 17 diameter.Capping 1 links with the form of screw thread and the top of epicoele 16, is sealed by rubber cushion 4 between them.Piston body 7 is one and has the cylindrical of step, and leather cup 8 leans against on the step surface, and it is by rubber cushion 9 and to be connected in the leading truck 11 of piston body 7 bottoms with thread forms fastening, and sealing gasket 10 is contained on the step surface of leading truck 11.One sealing gasket 6 is housed below the starter gate valve 5, is used for the upper-end surface of packed-piston body 7 center through hole.Outside at the water outlet place of valve body 14 has screw thread, and multiduty annex can spin.A tab 13 is housed on button 12, is used for the state of locking button.

Fig. 1 represents closed condition of the present utility model.During use, push button 12, promoting starter gate valve 5 makes it, at this moment, be stored in press water in epicoele 16 Seal cages on leather cup 8 tops in the valve body 14, make that hydraulic pressure reduces in the sealing chamber through the water outlet of the slanted gap flow valves of starter gate valve 5, under the effect of the bottom of leather cup 8 (linking) high pressure water with water inlet pipe mouth, piston body 7 pressure springs 3 move upward, and make sealing gasket 10 leave interior edge face between epicoele 16 and the cavity of resorption 17, drive valve and discharge water.Meanwhile, minimum partial pressure water reenters in the above-mentioned Seal cage through water chute 15, behind the dispensing button 12, starter gate valve 5 resets, and the low pressure of above-mentioned Seal cage and waterexit end separates, hydraulic pressure increases in the chamber, under differential pressure action, piston body 7 slowly moves down, to sealing gasket 10 when interior edge face between epicoele 16 and the cavity of resorption 17 contacts, valve is promptly self-closing, drain stop.

Button 12 has delay-self-closing and manual control is closed two kinds of functions.During use, push button 12 is to dispensing, then opens the valve back delay-self-closing that discharges water; If lift tab 13 on push button the time, make it push down button 12, then valve is often opened, and up to manually pressing down after tab 13 discharges button 12, valve just can be self-closing.The former is used for water in short-term, as need not remove closing valve again after washing one's hands, and clean hand can not pollute again; The latter is used for long-time water.

The utility model can be adjusted delay time, increases the thickness of spacer 2, can increase the elastic force of spring 3, and then piston body 7 moves down quickening, and the delay time of valve shortens; Otherwise prolongation delay time.
