The present embodiment mechanically stops the self-closing valve course of work are as follows: the valve is not in the case where cutting off the water, 4 He of reseting handle
Camshaft 3 is in original state, and water flow enters valve from water inlet 10, at this point, main spring retractable door 5 simultaneously by water flow pressure and
The effect of 6 elastic force of telescopic spring bar, since water flow pressure is greater than the elastic force of telescopic spring bar 6, telescopic spring bar 6 is compressed, main
Opening is formed between cam on telescopic spring door 5 and camshaft 3, i.e. main spring retractable door 5 is opened, and water flow passes through telescopic spring door
5 and camshaft 3 on cam between opening, flowed out by water outlet 11；(cut off the water moment) in the case where cutting off the water, reseting handle
4 and camshaft 3 be in original state, at this point, the only effect by 6 elastic force of telescopic spring bar of main spring retractable door 5, due to not depositing
In the pressure of water flow, telescopic spring bar 6 extends, and the main spring retractable door 5 of tightly fitting cam is gradually compressed, and works as telescopic spring
Bar 6 is elongated to the moment for making main spring retractable door 5 cross cam extreme higher position, and telescopic spring door 5 is rapid with the convex block of camshaft 3
Stuck, opening is blocked by telescopic spring door 5 completely, realizes water-stopping self-closing, when water, water flow cannot circulate.By clockwise
Spinning reduction handle 4 drives camshaft 3 to rotate, due to the scalability of auxiliary telescopic spring door 2,8, after rotating a circle, camshaft 3
Original state is returned to, realizes the reset of valve, water flow can normally circulate.Cooperation ordinary faucet is used together compared with electric-controlled tap
It is safer, efficient, application range is wider.
When fluid is the gases such as other liquid or coal gas, natural gas, this cutout self-closing valve also can achieve same machinery
The effect of the self-closing cutout of formula.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
