Abstract

The utility model relates to a delaying automatic closing flushing valve which is composed of a delaying automatic closing transmission body used as a valve core and an existing tee valve body, wherein the delaying automatic closing transmission body formed integrally is mainly composed of a transmission rod, a load relief sleeve, a damping hole body, a restoring spring, a sealing assembly, etc. The utility model is characterized in that fall load relief states and the automatic closing purpose are realized; a delaying range is from 5 to 8 seconds; the utility model saves water, provides convenience for flushing operation, effectively overcomes the common water leaking, emitting, dripping and seeping phenomena of water of general water valves and flush toilets and can be disassembled, assembled and maintained or replaced without changing an original pipe passage to really save water and materials.

Description

A kind of delay-self-closing flushing valve

The utility model relates to a kind of simple and easy, convenient delay-self-closing flushing valve of economizing on water.

The flushing valve of existing patent oil control delay-self-closing, the patent No. 94241247.8, function admirable is spoken approvingly of by the user deeply.But since its can not with existing general triple-valve body directly by adaptive, thereby its cost is higher, the technical requirement of installation, maintenance is also high, and is universal limited.

The purpose of this utility model is to overcome above-mentioned shortcoming, provide a kind of assembling, maintenance and use all easily, the long delay-self-closing flushing valve of low, life-span of cost.

The utility model is by the custom-designed delay-self-closing transmission body of using as spool and existing triple-valve body is suitable forms.This transmission body is to be base or supporting body by the transmission body shell that can be fixed on the valve body, the up-thin-low-thick column drive link that will have through-core hole runs through therebetween, be nested with off-load cover, sealing ring, unloading spring, rubber cup, back-moving spring, big gland, seal member and the damping hole body etc. of unloading hole from bottom to top on the drive link, logical damping control is closed automatically also and can be had a style of one's own in the formation, realizes that whole unloading conditions strengthen the flushing dynamics.

Provide embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1. delay-self-closing transmission body cut-away view;

Fig. 2. former triple-valve body cut-away view.

Wherein: 1. damping hole body, 2. big O type circle, 3. switch rubber cushion, 4. rubber washer, 5.O RunddichtringO, 6. delay-self-closing transmission body, 7. off-load cover, 8. adjusting ring, 9. adjustable ring, 10, the transmission body shell, 11. big glands, 12. sealing cap, 13. handle switches, 14. drive links, 15. the skeleton envelope, 16. sealing rings, 17. back-moving springs, 18. leather cup, 19. unloading springs, 20. triple-valve bodies.

Symbol description: A is a damping hole; B, C, D, E, F are unloading hole; H is former triple-valve body unloading hole; G is a seam.

As shown in the figure, the utility model is combined by delay-self-closing transmission body 6 and existing triple-valve body two parts.Drive link 14 in the above-mentioned delay-self-closing transmission body 6 is for running through the up-thin-low-thick column of transmission body shell 10, there is the radial direction through hole E at through-core hole F and middle part place to communicate in it, and drive link 14 is being nested with the off-load cover 7 that is the I shape cylindrical cavity from bottom to top, tightly be stuck in thick cylinder position week along two O RunddichtringOs 5 in the groove, unloading spring 19, rubber cup 18, certain flexible back-moving spring 17 is arranged, the discoid big gland 11 of band screw thread, and the skeleton that seals envelope 15 and sealing cap 12.Wherein, unloading spring 19, rubber washer 4 and two O RunddichtringOs 5 are enclosed in again in the off-load cover 7.It is suitable to be provided with the external screw thread of funnelform damping hole body 1 of being of damping hole A and internal thread that 7 lower ends are overlapped in off-load, and making it its damping hole A can communicate with unloading hole F, E and D; The switch rubber cushion 3 of being responsible for break-make tightly is stuck in the peripheral groove of damping hole body bottom, piston type rubber cup 18 is fixed on the upper end of off-load cover 7, the inwall of its radial dimension and transmission body shell 10 matches, pulling drive link 14 can drive its directed slip, to have suitable flexible back-moving spring 17 and above-mentioned all assemblies all to be packaged in the bottom has within the transmission body shell 10 of unloading hole C, and with sealing ring 16, with the suitable big gland 11 of transmission body shell 10, skeleton envelope 15 and sealing cap 12 seal transmission body shell 10 upper ends, to prevent that water from leaking from transmission body shell 10 upper ends, 13 on switch of handle is fixed on the top of the drive link 14 that is exposed at transmission body shell 10, more than form one and constitute main body of the present utility model---delay-self-closing transmission body 6, its delay time mainly is subject to size and the water injection rate of damping hole A, is controlled at usually to be advisable for 5～8 seconds.

Above-mentioned delay-self-closing transmission body 6 is the external screw threads via transmission body shell 10, adjustable ring 9, sealing adjusting ring 8 is enclosed on the G seam of valve body 20 admittedly, and the big O type circle 2 that the H hole that guarantees valve body 20 is embedded in the groove on transmission body shell 10 bottom faces seals, and the H hole is communicated with the B hole.

Drive link 14 of the present utility model, transmission body shell 10 etc. are for preventing the copper part of corrosion, and damping hole body 1, off-load cover 7 are made for engineering plastics.

Time-delay transmission of the present utility model and switch remain good state, realized full unloading condition and closing automatically, the delay-self-closing transmission body is had a style of one's own in addition, need not turn former pipeline dismounting and maintenance easily, makes the common disadvantage of flush toilet be improved solution.
