Abstract

The utility model discloses a time-delay valve, which comprises a valve body with a water inlet and a water outlet, a partition board used for spacing influent and effluent water in the valve body, and a time-delay cavity used for controlling discharging time. The middle of the partition board is provided with a through hole, a floating body passing through the through hole is arranged in the time-delay cavity, a valve core is arranged above the floating body, the inner side wall of the time-delay is provided with a water guiding slot at the point matching with the valve body; water flows into the time-delay cavity through the water guiding slot which is arranged on the inner side wall of the time-delay cavity at the point matching with the valve body, the arrangement of the water guiding slot has the characteristics that the structure of the water guiding slot is simple; the water guiding slot can not be easily plugged by impurities. Therefore, the water can favourably flow into the time-delay cavity; the delay-time effect of the delay-time valve is stable and reliable.

Description

A kind of time-delay valve

Technical field

The utility model relates to a kind of valve, especially a kind of time-delay flushing valve.

Background technique

Time-delay valve in the past, it mostly is perforate on buoyancy aid, on the hole, cover filter screen then, water enters the time-delay chamber by filter screen from the hole on the buoyancy aid, this time-delay valve is the structure more complicated not only, and the time grown filter screen and stopped up by the impurity in the water easily, cause water can not enter the time-delay chamber or to enter the water level of water in time-delay chamber not enough, do not have the effect that reliable and stable time-delay control discharges water.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of delay effect time-delay valve reliable and stable and simple in structure.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of time-delay valve, comprise bring into, the valve body of water outlet, the time-delay chamber that the dividing plate and the control discharge time of water-in and water-out are at interval arranged in the valve body, the centre of dividing plate has through hole, in the time-delay chamber, buoyancy aid is installed by through hole, the top of buoyancy aid is equipped with spool, on the madial wall in time-delay chamber, have gutter with the cooperation place of buoyancy aid.

The beneficial effects of the utility model are: because the time-delay chamber is on the madial wall by the time-delay chamber, with the gutter water inlet of the cooperation place of buoyancy aid, the setting of this gutter is not only simple in structure but also be not easy to be stopped up by foreign material, so the water inlet of time-delay chamber smoothly, the delay effect of time-delay valve is reliable and stable.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

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

Embodiment

With reference to Fig. 1, a kind of time-delay valve, comprise bring into, the valve body 1 of water outlet, the time-delay chamber 3 that the dividing plate 2 and the control discharge time of water-in and water-out are at interval arranged in the valve body 1, the centre of dividing plate 2 has through hole 4, buoyancy aid 5 is installed in time-delay in the chamber by through hole 4, the top of buoyancy aid 5 is equipped with spool 6, on the madial wall in time-delay chamber 3, have gutter 10 with the cooperation place of buoyancy aid 5.

The working principle of this time-delay valve is: when needs are washed by water, press lower valve core 6, the buoyancy aid 5 that is movably arranged in the time-delay chamber 3 moves down, simultaneously, valve rod 11 in the buoyancy aid 5 slit occurs with the surface of contact of planar seal ring 12, water in the time-delay chamber 3 flows out from this slit like this, when buoyancy aid 5 is displaced downwardly to the through hole 4 of its upper end disengaging dividing plate 2, water inlet was communicated with water outlet moment, and water flows to water outlet from water inlet, because the outer intake pressure of dividing plate 2 is greater than the hydraulic pressure in the time-delay chamber, so this moment, buoyancy aid 5 continued to move down into maximum displacement place under the effect of hydraulic pressure, it is maximum that the moment water-outlet quantity of water outlet also reaches simultaneously, is enough to wash away dirt, satisfies and use needs; On the other hand, the water that water intake is come in injects time-delay chamber 3 from the gutter 10 on the madial wall in time-delay chamber 3, when the water level of time-delay in the chamber 3 reaches certain water level, water with buoyancy aid 5 upwards jack-up up to buoyancy aid 5 through hole on the dividing plate 24 is closed, entery and delivery port is spaced, thereby water outlet stops water outlet, realizes the effect that time-delay control discharges water.

In the middle of present embodiment, between the diapire in the lower end of buoyancy aid 5 and time-delay chamber 3 Returnning spring 8 is arranged, can guarantee the sealing of the through hole 4 on buoyancy aid 5 and dividing plate 2 under the situation of not bath like this, leak to prevent time-delay valve; Leading truck 7 is housed in the valve body 1, and spool 6 is installed in the leading truck 7, and leading truck 7 can play the effect to the motion guide of spool 6, thereby can improve the stability of time-delay valve work, in addition, trim 9 is equipped with at the handle place on valve body 1, makes that like this integral body of time-delay valve is more attractive in appearance.
