Embodiment Construction
[0010] The present invention will be further described below in conjunction with the accompanying drawings.
[0011] Such as figure 1 , as shown in Figure 2, an automatic flush valve for a urinal includes a main body 1 and a valve body, the valve body 2 has a water inlet 21, a water outlet 22, a stool liquid inlet 23 and a stool liquid chamber 24 at the top, The main body 1 has a stool inlet 11 and a stool outlet 12, and the stool liquid inlet 23 is opposite to the stool inlet 11, and also includes a static pressure valve plate 3, a pressure spring 4, a valve stem 5 with a valve core, and a valve stem trigger mechanism 6. The chamber between the static pressure valve plate 3 and the valve core constitutes the static pressure chamber 7; the stool chamber 24 cooperates with the valve stem trigger mechanism 6;
[0012] The valve body 2 also has a mounting chamber 25 for the valve stem trigger mechanism, a valve stem channel 26, a valve core seat 27, a valve seat, and a sealing c...

The invention discloses a urinal automatic flushing valve, comprising a main body, a valve body, a static pressure valve plate, a pressure spring, a valve rod with a valve core and a valve rod trigger mechanism, wherein a static pressure chamber is formed between the static pressure valve plate and the valve core; a urinal liquid chamber is matched with the valve rod trigger mechanism; the valve body is provided with an installation chamber, a valve rod channel, a valve core seat, a valve plate seat and a seal chamber above the valve plate seat; the valve rod channel is communicated with a water outlet, and the static pressure chamber is communicated with a water inlet; a water outlet channel is communicated with the water outlet in the seal chamber, and a plugging mechanism of the water outlet channel is arranged above the seal chamber; the plugging mechanism is opposite to a urine liquid inlet. By adopting the structure, when the urine liquid in a liquid tank reaches a certain weight, the valve rod trigger mechanism is operated to lead the water in the water outlet into the water outlet through the static pressure chamber and the seal chamber to flush the urinal; when urine is completed, the liquid tank restores, the flushing action is finished, and the water source is closed.
Description
technical field [0001] The invention relates to a waterway control valve, in particular to an improvement of an automatic water valve, that is, an automatic flush valve for a urinal, and belongs to the technical field of water heating valves. Background technique [0002] Present prior art, the urinal flush valve of a kind of electric self-control on the market at present all must use electricity or press by hand. Disadvantages of using electricity: Some dry batteries need to be replaced frequently, which is cumbersome and not environmentally friendly; there are also power sources, for example, there is no way to flush water when the power is off; disadvantages of pressing by hand: it is generally considered dirty in public places, so they are unwilling to press. Contents of the invention [0003] The object of the present invention is to provide an automatic flush valve for a urinal, which can effectively overcome the deficiencies in the prior art. It has the characterist...
