Time-delay flushing valve

Abstract

The invention provides a time-delay flushing valve. The valve comprises a valve body, wherein the valve body is provided with an upward opening; a rigidity adjusting rod is arranged in the valve body in a sliding way; a returning spring is arranged between the lower end of the rigidity adjusting rod and the inner bottom surface of the valve body; the top of the returning spring is fixedly connected with a button which extends out of the opening of the valve body; a pore which is communicated with the water inlet of the valve body is formed on the rigidity adjusting rod; after being bent, the pore extends downwards to the bottom of the rigidity adjusting rod; the lower part of the pore is provided with a round platform; an elastic water-introducing casing with a water introducing pore is arranged in the round platform; a round platform which is matched with the round platform with the pore is arranged on the elastic water-introducing casing; a hollow rigidity gland is pressed against the lower part of the elastic water-introducing casing; and the gland is in threaded connection with the inner wall of the pore. The pore diameter of the water-introducing pore of the elastic water-introducing casing which is clamped between the gland and the adjusting rod can be changed by tightly or loosely screwing the gland, so that the delay time of the time-delay flushing valve can be adjusted according to the actual service condition.

Description

technical field [0001] The invention relates to a flushing valve, in particular to a delay flushing valve. Background technique [0002] Now, delay flushing valves are widely used in public places such as public toilets, stations, hotels, etc. On the one hand, they can effectively save water. It is very convenient to operate without having to touch the faucet with your hands. A delay valve is disclosed in CN2733129Y, which includes a valve body with an inlet and an outlet. The valve body has a baffle for separating the water inlet and outlet and a delay chamber for controlling the water discharge time. A through hole is provided in the middle of the baffle. A floating body is installed in the time-delay chamber through the through hole, a valve core is installed above the floating body, and a water diversion groove is opened on the inner side wall of the time-delay chamber and at the matching place with the floating body. However, in the existing above-mentioned time-delay...

AI Technical Summary

Problems solved by technology

However, in the existing above-mentioned time-delay valves, the time-delay performance of the time-delay valve (mainly determined by the aperture of the water diversion tank) has been set at the factory, and cannot be adjusted according to actual usage conditions. Therefore, the same When the delay valve is used for faucets with different water supply pressures and different water supply temperatures, it can cause delay time differences (generally fluctuating within 3 to 15 seconds). At this time, if the delay time is longer, water saving cannot be achieved. requirements, and if the delay time is short, the user needs to press the button again to meet the water volume requirements, which is inconvenient to use
